Sanji/Relationships

Crew
Sanji first met the crew after Luffy accidentally attacked the Baratie. His first impression was that they were a "noisy bunch" but catching a glimpse of Nami caused Sanji to swoop over. It took a while for Sanji to fully understand and like the crew, since he thought Luffy and Zoro were crazy for risking their lives for their dreams, when they respectively fought Krieg and Mihawk; however, seeing their determination and recalling his own dream of finding the fabled All Blue, Sanji is inspired to pursue his own dream. After joining the crew, Sanji would often butt heads with Zoro and argue with Usopp, as well as seeking out Nami's company, but after fighting together at Arlong Park, he warms up to the whole crew (including Zoro, to an extent), making huge feasts for them and taking pleasure at their happiness. Just before the entered the Grand Line, it was Sanji who proposed a launching party, during which all of the members who joined in East Blue declared their commitment to achieve their dreams.

Sanji often states that he only cares about the women of the crew, but this is far from true. Sanji cares for all his friends, and between his heroic rescue at Rain Dinners and by closing the Gates of Justice at Enies Lobby, it can be said Sanji has saved the entire crew on numerous occasions. When Sanji was unable to protect his crew from Kuma, Sanji became distraught and charged at the Warlord, despite Usopp trying to hold him back. When given a difficult challenge by Ivankov, Sanji said he would go through (his idea of) "hell" for his crew and accepted the challenge. He has also risked his life for the crew on multiple occasions, whether it be by taking lightning blasts from Enel, or stopping Doflamingo from reaching the crew. Even after meeting his beautiful, arranged fiancée, Charlotte Pudding, he turns her down and chooses to return to his friends. After Pudding tells the crew that Sanji turned her down for them, they are shocked to the core that Sanji would turn down a woman, let alone such a beautiful and (seemingly) kindhearted one; Luffy is so moved by Sanji's loyalty that he even cries. While fighting his father, the latter questioned if Sanji would really sacrifice his own family to which Sanji stated he did not care what harm came upon them as he only came to protect his crew. It can be said that Sanji sees his crew as the real family he never had growing up. Sanji's care for his crew even enters his subconscious thought, as when he was preparing a bento box for Pudding, he realized he put all their favorite foods in the meal.

However, with explosive shackles placed on his hands, Zeff's life being held hostage by the Germa Kingdom, and his crewmates threatened by the Big Mom Pirates. Sanji reluctantly decided to sever his ties with the Straw Hat Pirates, speaking cruelly and insultingly to Luffy and Nami in the hopes to chase them away, to the point of pretending he arrogantly forgot Luffy's name. To further his goal of stopping the crew from pursuing him, Sanji continued on with his words and violently attacked Luffy but was driven to tears afterwards. Sanji also made sure the crew would survive Whole Cake Island agreeing to Big Mom to marry Pudding so long as the crew were safe, until he realized the entire marriage is a sham to kill him and his family, and that Big Mom never intended to spare the Straw Hats.

After Sanji realized his misgivings, he rushed off with the bento box to find his captain. After arguing with Luffy, Sanji finally wept and admitted that he wanted to return to the Thousand Sunny. He also said to Luffy that he could not abandon his family, so Luffy told Sanji that they would destroy the wedding together. Sanji was very reluctant to face the crew again but were overjoyed to hear them through Brûlée's mirror shard. His crewmates, particularly Brook, Luffy, and Chopper, dearly enjoy his delicious cooking, and began to better appreciate him after Luffy's disastrous wastage of their food supply by cooking the disgusting Random Curry. They were extremely overjoyed at being able to taste his cooking again to the point they joyfully hugged Sanji. After safely reuniting with the crew, Sanji has shown to be more caring and protective towards the male members of the crew as he angrily swore to go all out to protect Usopp if he were to be captured by the Beasts Pirates.

Monkey D. Luffy
Agh, jeez... Looks like I've chosen a dumbass for my captain... But it's still a hundred times better than being in a pirate crew that would harm a lady.



The two first met when Luffy was forced to work as a choreboy in Baratie to pay for the damages he caused. Luffy thought highly of Sanji not only for his skills as a master chef but also for his kindness by generously feeding a starving Gin, which made Luffy determined to recruit Sanji into his crew as their chef. Sanji developed an initial bond with Luffy in that they both had dreams that were deemed foolish: Luffy was often not taken seriously for wanting to be the Pirate King, and Sanji was often told that All Blue did not exist. However, they both had mentors who made great sacrifices for them (Shanks gave up his left arm to save Luffy, and Zeff gave up his right leg for Sanji), and ultimately gave them the motivation to believe that they could achieve their dream.

Sanji respects Luffy as a captain, but often gets angry at him for eating too much, showing disrespect for the aesthetics of cooking, or stealing food rations in which he often put a giant mouse trap near the refrigerator or locks it. Along with Nami, Sanji is the crew member who beats up Luffy the most often. He also dislikes Luffy's imitations of him, although this may also be because of their inappropriate timing, rather than the imitations themselves. Sanji often says he chose an "idiot" for a captain, but conversely states that Luffy is far better than most pirates. Luffy quite often asks him to cook an animal that he's defeated, and Sanji rarely objects. In spite of Luffy's gluttony, he does care for Luffy, and, as the best swimmer on the crew, he is shown dragging his captain out of the water more often than any of the other crew members. When the crew met Luffy's grandfather Monkey D. Garp, Sanji was surprised by Luffy's connection to a legendary marine but stated he understood Luffy's personality and strength after hearing about his training. However, he was stunned to hear Luffy was the son of the world's most dangerous criminal and that Luffy never heard of him.

Sanji rarely shows shock or surprise at some of Luffy's outrageous actions and decisions. In fact, he is often one of the people to assure the rest of the crew or other people that Luffy knows what he is doing. In Thriller Bark, Sanji volunteered to give his life in exchange for Luffy's but was stopped by Zoro.

After the timeskip, Sanji and Luffy still got along. However, Sanji becomes envious of Luffy after finding out that Luffy landed on Amazon Lily and befriended Boa Hancock while he was in 'hell'. Despite that, he was in awe at Luffy using Haoshoku Haki and impressed that his captain was capable of such a feat.

When Bege stated that the crew would fall under Big Mom's wing via Sanji's marriage to Pudding, Sanji ferociously rejected the idea, saying that Luffy would never bow to anyone else and even boldly stating that Luffy will become the Pirate King.

Sanji and Luffy have a great trust in each other as seen most recently when Luffy trusted Sanji to fight off Big Mom's crew near Dressrosa and travel all the way to Zou while protecting Caesar, Momonosuke, and the rest of the crew from danger. Sanji succeeded and Luffy was confident that Sanji could look after himself even when the cook was missing from Zou, but Luffy became concerned when he learned that Sanji had gotten entangled in Big Mom's political plans and decided to go retrieve him from his "wedding" to Pudding. When Luffy heard from Pudding that Sanji had turned her down so he could return to his crew, Luffy was so grateful that he cried and became more determined to save him. When Charlotte Cracker told Luffy that Sanji would most likely be happy with the Charlotte Family and turn away from the Straw Hats, Luffy angrily attacked him, telling him not to put words in Sanji's mouth.

When Sanji actually said what Cracker said to Luffy directly after violently kicking Luffy off the Cat Carriage, and then telling him to be gone, Luffy immediately expressed his doubt over Sanji's words as being sincere. Luffy then opted to not defend himself or run away when Sanji proceeded to beat him without mercy, and after being defeated, Luffy brings Sanji to tears when he expresses that he will still not turn his back on him. Furthermore, Luffy feels strongly enough about Sanji's defection that he refuses to move or eat until Sanji returns and cooks for him, preferring to die rather than continue without him. Luffy refused to leave his waiting spot and true to his own words refused to eat or drink, contrary to his extremely gluttonous nature and fought a majority of Big Mom's crew in a hungry and exhausted state as he waited for Sanji. Even while seriously wounded, Luffy stubbornly refused to move and had to be knocked out and taken captive. Sanji later requested that Big Mom spare Luffy's life by agreeing to marry Pudding, and he was relieved when Big Mom said she agreed to Sanji's terms until he learned of Pudding and Linlin's true intentions.

Sanji could not forgot his care for his captain, as when Bobbin tried to eat the meat (meant for Luffy) from Sanji's bento box, Sanji became enraged and kicked down the pirate, inadvertently risking Zeff's life in process. This is worth noting as Sanji almost never denies anybody food, but he obviously cared more for his starving captain than about keeping his deal with the Big Mom Pirates. Sanji traveled through Sweet City and soon found his captain at the spot that he promised to meet with him, which brought a smile to his face. Sanji then gave Luffy the bento box he made (despite it being ruined in his journey), thus relieving Luffy of his hunger. Afterwards, Sanji gave his reasons as to why he could not return to the crew and was punched in the face by Luffy, who told him to admit the truth and Sanji told him that while he is conflicted over wanting to save his family despite their cruel treatment, he nonetheless wanted to return to the crew and Luffy complimented that Sanji is truly kindhearted and he will help him ruin the wedding ceremony.



Sanji's belief in Luffy was really shown as when Pudding informed him of Luffy's battle with Charlotte Katakuri, Sanji expressed his confidence that Luffy would somehow prevail, and that Katakuri's then-untouched victory record would be broken. When Luffy emerged from the Mirro World, Sanji fought through an army of the Big Mom Pirates and carried his captain away. Sanji even suffered injuries to his own person but refused to let the vengeful enemy crew touch his captain. When Judge badmouthed Sanji about the things he despises about Sanji, Luffy considered all of the traits to be virtues.

After Sanji returned to the Straw Hats and they escaped Totto Land, Luffy was very happy to have him back and was gluttonously elated to hear him say he was going to cook. He even begged Sanji to keep the Raid Suit he received from Niji even though Sanji made it clear he wanted nothing from his family.

Roronoa Zoro


Though they can behave casually and calmly towards each other, Sanji very frequently gets into physical and verbal fights with Zoro (who he refers to as "marimo" or "mosshead" because of his green hair); in turn, he is nicknamed "shitty cook", "ero-cook", "Mr. Nosebleed" and "Prince of Dumbass Kingdom" (among other things) by Zoro. During the Little Garden Arc, Sanji and Zoro unknowingly took on the same challenge of dinosaur meat hunting that the two legendary giants, Dorry and Brogy, started 100 years ago. Despite their rivalry, however, the two respect each other's abilities; after Wanda accidentally implied that the minks had killed the Curly Hat Pirates, it is Zoro who calms the others down by reminding them that Sanji was with them, and that he would not have let half of the crew get killed.

Although he spends a lot of time arguing or competing with Zoro, Sanji is not beneath siding with Zoro on those rare occasions where Zoro has seen the bigger picture more than everyone else (e.g., on their preference for death rather than dishonor during the Davy Back Fight, and on Usopp rejoining the crew). He also tried to stop Zoro from sacrificing himself to Kuma to save everyone else by offering his life instead, although the swordsman knocked him out first before he could do so. After waking up to find Zoro missing, he showed great concern at what may have happened to him and was the first to find Zoro in the aftermath of Kuma's attack. Furthermore, although their rivalry sometimes impedes their effectiveness during battle, once the two agree to work together, they become a near-unstoppable force.



Sanji seems to understand Zoro on a personal level as well, even before he joined the crew. When he witnessed Zoro's defeat against Dracule Mihawk, he recalled Zoro telling him earlier that day that his ambition to be the greatest swordsman meant that he threw away all attachment to his own life, and he was perplexed that Zoro would not abandon his ambition in the face of almost certain death. When the Risky Brothers were going to tell the crew of Zoro's sacrifice, he told them not to do so on the basis that he knew Zoro would not sell his life for gratitude. Sanji also demonstrated this to the G-5 Marines on Punk Hazard, as they seemed to be under the impression that Zoro is ruthless and would cut down anything. He assured them that Zoro does indeed have a soft side, and that Tashigi should be just fine with him there, stating that he is the kind of person who gets the job done. When Sanji was allegedly losing his human compassion due to his genetic modifications awakening, he entrusted Zoro to be the one to kill him if he (Sanji) ever goes astray, something Zoro agreed to without questioning in details.



Sanji has consistently been frustrated at his bounty in comparison to Zoro's. After the Arabasta Arc, he was annoyed that Zoro received a bounty while he did not. After their battle at Enies Lobby, although he finally received a bounty, Zoro's increased enough that it remained higher than his. Although he was not there to express his annoyance, Zoro's bounty remained higher after the battle at Dressrosa. It was not until escaping Whole Cake Island that Sanji's bounty became greater than Zoro's, which made him wildly shout in joy. Sanji holds a jealousy towards Zoro for saving Kozuki Hiyori. After Kaidou's defeat, Sanji shown more jealousy towards Zoro when he gotten attentions of Hiyori. He was also dismayed that Zoro's bounty was once again higher than his after they left Wano. Zoro insulting Sanji by referring him as "number 4" and himself as "Crew's 2nd" causing Sanji to fight against Zoro.

Nami


The moment Sanji saw Nami in the Baratie, he was enamored with her and tried to flirt with her as he does with the other women he encounters. Nami, on her part, was pleased she was getting special attention, leading her to manipulate the cook numerous times. Sanji appears to be well aware of this manipulation but is happy to continue being constantly subservient; in fact, Sanji has claimed that 98.72 percent of the reason he was joining the crew was because of Nami, despite not actually being true. He is kind to her, as he is to all women he comes into contact with. Sanji does occasionally get on Nami's nerves, such as when he makes a declaration of love during serious moments. Sanji will sometimes anger Nami, and she does not hesitate to beat him up (though he does not seem to mind). This was most notably shown when Trafalgar Law used his Devil Fruit powers to switch Sanji into Nami's body; Sanji's perverted delight at being in her body caused Nami to freak out and become furious with him. When they switched back, she punched Sanji for changing her coat (a misunderstanding caused by her assuming that he had stripped to see her body), despite him taking great care of her body while she let his get damaged. Sanji hates treating Nami roughly in any manner and is always gentle with her; this is another reason why Sanji fights with Zoro as the swordsman is prone to shoving Nami roughly out of peril. However, if she is immediate danger, Sanji will throw Nami out of harm's way as well, as was seen when she and the others were trapped inside Capone Bege. When Zeus joins Nami as her newest servant, Sanji stakes his claim of being her servant first and foremost.

Sanji will not tolerate Nami being insulted or harmed in any way, like when Kuroobi bad-mouthed her causing Sanji to send the fish-man flying. Her safety is a frequent cause of his own injuries, such as on Drum Island when Nami was gravely ill, and Sanji joined Luffy in taking her to the doctor's and got his spine cracked as a result of the avalanche caused by the Lapahns, in Skypiea when Sanji went aboard the Ark Maxim with Usopp to save her from Enel only to be blasted by the God for his heroics, and on Thiller Bark when Nami was kidnapped by Absalom to become his bride, Sanji (furious at the prospect of Nami marrying another man) went alone to rescue her and got knifed in the shoulder while protecting her. Sanji was also angry at Jinbe when he admitted he was the one who let Arlong loose on East Blue, which resulted in Nami's experiences under Arlong's reign, and it was only due to Jinbe's friendship with Luffy that he gave Jinbe a chance to explain himself; however, even after listening to Jinbe's story, he still could not forgive him for what Nami went through he suggested that if Jinbe wished to atone, he should cut open his own belly (he only relented after Nami defended Jinbe). Sanji trusts Nami very much and not just by her navigator skills; Nami was the one who Sanji entrusted the letter to Luffy to and directly apologized for keeping secrets from her and the crew.

Despite her occasional annoyance at his antics, Nami does care for and respect Sanji. She considers him very dependable and will often hide behind him when there are enemies nearby. When she heard that he was going up against CP9 on the sea train, she expressed concern for his safety, and even fought Kalifa for him when he refused to fight the assassin. On Zou, Nami was distraught after Sanji was taken by the Big Mom Pirates, and she accompanied Luffy to see Pekoms so she could learn as much as possible about Sanji's family (which led her to discover, much to her disbelief, that Sanji was closely connected with Germa 66). She also demanded that Luffy allow her to accompany him to retrieve Sanji, saying that she felt partially responsible for what had happened to him. While facing problems in the Seducing Woods, when it appeared they had found Sanji who was running away from them, Nami stated it could not be him as he would never put his friends be in danger.

Nami is one of the four Straw Hats (along with Luffy, Chopper and Brook) to have met members of Sanji's family. She was very surprised to learn that Sanji had a younger brother but stated that, save for his attraction to her, the latter had nothing in common with Sanji due to his selfish nature. Nami was even more surprised to meet Sanji's elder sister and learn the history of his family. When meeting Sanji's arranged fiancé, they were all shocked that Sanji turned down the kind and attractive woman to return to the crew.



When Nami saw Sanji again, she was happy to see him again, but their excitement was short-lived as Sanji (reluctantly) tried to get them to leave Whole Cake Island by kicking Luffy away and acted as if he embraced his royal heritage. Nami was speechless and heartbroken at Sanji's supposed change in personality as he went on to insult them because of their peasant status. Nami was shocked to see Sanji attack a non-retaliating Luffy while insulting the crew and their dreams and was even scared when he gave her a vicious glare to silence her (something he never did before). After the confrontation, a tearful Nami approached Sanji and slapped him across the face while not using her usual "-kun" honorific for him, signifying a loss of respect. She angrily and sarcastically bid him farewell on his journey while Sanji is unable to look her in the eye and instead simply walks away after the strike to his cheek. As Sanji rode away in the carriage, Nami cried in earnest and even attempted to get Luffy to abandon trying to rescue Sanji. When his crewmates were captured by Big Mom's forces, Sanji believed he saved their life by agreeing to marry Pudding.

After coming to understand the situation, Nami was deeply saddened by Sanji's troubles and once again becomes determined to rescue him and bring him back to the crew at all costs. While she does tell him that she'll never forgive him for the despair he put her through, she's willing to put that aside for the sake of rescuing him. While taking the never forgiving part as a pierce to the heart, Sanji then mistook her claim of putting it aside as a marriage proposal and returned to his love-struck personality with her.

Despite her promise of never forgiving him, she was happy when he saved her from hitting the ground after his sister freed her from Smoothie's grasp and referred to him as “Sanji-Kun” again. When he returned to the crew officially, Nami (along with Brook and Chopper) gave Sanji a tight hug with tears in her eyes, causing Sanji to get overexcited and flip out, which caused Nami to evade him when he tried to hug her back several times. When Nami revealed she had Zeus serving her, Sanji angrily told the homie that he was Nami’s servant long before it showed up.

When Nami caught Sanji using his new Raid Suit's invisibility power to peep at women (herself included) in a public bathhouse, she brutally beat him up for it even though he saved her, Robin, and Shinobu from X Drake and Basil Hawkins.

Usopp
I'll do what you can't do. And you do what I can't do!

While he argued with Usopp on their first meeting, Sanji soon became good friends with Usopp and is often seen hanging out and/or partying with him. Despite this, he occasionally beats him and Luffy up when they do something immature, like eat too much food or goof off in serious situations. Usopp also declares that Sanji is his "bodyguard" and clings onto the cook in dangerous situations Sanji always shrugs him off, saying he is only Nami's bodyguard.

Though he acts like he does not care about Usopp, Sanji tried desperately to stop Usopp from leaving the crew and did not hesitate to attack Luffy to prevent him from telling Usopp to leave the crew, proving his commitment to his friends and the crew. Usopp finds Sanji's girl crazy attitude annoying at times especially when they are in direct danger, berating Sanji on his "one track mind". During the Skypiea Arc, he does not hesitate to tell Usopp that he's OK with him dying if it meant that they could save Nami; however, just as Usopp was about to take a potentially fatal attack from Enel, Sanji kicks him out the way so that he can escape with Nami and takes the attack himself. Furthermore, during the Enies Lobby Arc, it is Sanji's advice that helps Usopp realize his value to the crew, after Usopp had left the crew under the false belief that he was weaker and more useless compared to everyone else on the crew. Sanji also understood Usopp's frustration wanting to help Robin but not able to face the crew and accepted the crazy "Sogeking" disguise despite Franky being confused.

When Sanji cried in happiness at Mermaid Cove, Usopp was shocked and asked Sanji what happened to him over the past two years. After Sanji left the crew in the Zou Arc, Usopp was worried Sanji would go "lovey dovey" and agree to marry Pudding. Usopp was deeply relieved when Sanji was rescued from Big Mom's clutches and was happy to be able to taste his cooking again. Contrary to his previous harsh attitude, Sanji is notably more caring and protective of Usopp since they reunited as he swore to protect Usopp at all costs from being captured by the Beasts Pirates. During the raid on Onigashima, Sanji became jealous of Usopp riding inside the Brachio Tank V with Nami and Carrot and implored Usopp to let him in. In response, Usopp said the cook was “unfit” to drive such a vehicle. One of the biggest examples of Sanji's respect for Usopp is when Sanji easily entrusted the sniper to look after Nami when they were being pursued by Page One and Ulti, despite the previous times where Sanji got furious at Usopp for failing to prevent Nami from getting hurt or captured like at Thriller Bark.

Tony Tony Chopper
Sanji originally wanted to cook Chopper and continues to refer to him as their "emergency food supply" to tease him. However, he does consider Chopper a good friend, and will give him or Usopp advice when they need it. Sanji, along with Luffy and Nami, was the first in the crew to treat Chopper with any kindness, like when he heard about Chopper's past being rejected as monster. When the reindeer asked him what Luffy was, Sanji replied that he was a "Monster" smiling. An ongoing theme of Chopper's personality has been that his age and sometimes childish nature allow for him to be more susceptible to advice from the crew. A lot of this advice has come in the form of what it takes to be a real man, and to this end, Sanji has taught Chopper quite a few lessons. Before the real reason as to Robin's betrayal is revealed, he tells Chopper that when a woman lies, a real man forgives her. Upon Usopp's defeat in his fight with Luffy, he taught Chopper not to stomp on a man's pride and resolution by showing him pity in the face of defeat.

At the same time however, Sanji is very understanding of Chopper's childish nature and will appease it when he feels necessary. For example, he agreed to help him warn Usopp about Aqua Laguna despite Usopp leaving the crew, as he saw how much Chopper was worried about Usopp. Furthermore, he played along with Usopp's Sogeking persona, knowing that Chopper fully believed in Sogeking, whereas he had worry greatly about Usopp.

Chopper also finds Sanji's strength and fighting power "awesome", especially Sanji's burning rage aura (which Chopper beheld in awe) and Chopper was even happy to be in Sanji's body in Punk Hazard. Sanji treats Chopper the best out of all the males of the crew, rarely hurting him in any way and even shows concern whenever Chopper hurts himself while being clumsy. Chopper is the same towards the cook, hiding behind Sanji's leg when he was scared of Nami’s anger at Skypiea, causing Sanji to reach down and pet Chopper’s head in a comforting manner. Sanji (much like Zoro and Franky) will even give Chopper shoulder rides.

During the Zou Arc, Chopper (along with Nami and Brook) was absolutely distraught over Sanji's departure with the Big Mom Pirates, and so decided to accompany Luffy in retrieving Sanji from Whole Cake Island. Chopper was so hopeful about seeing Sanji again that he initially mistook Sanji's malicious younger brother for him. Chopper was also the Straw Hat most amazed at noticing that Sanji's curly eyebrows were common amongst all the Vinsmoke children. Along with the others, Chopper was very surprised that Sanji turned down Pudding to stay with the crew. During Big Mom's Tea Party, Chopper assisted Sanji in rescuing his family from Big Mom's clutches. Chopper dearly adored Sanji's cooking and happily cheered and hugged the latter when he was going to cook a meal for them again.

Nico Robin


Sanji's first meeting with Robin was surprisingly hostile, as he pointed a gun at her head (due to Robin being a threat to the crew at the time), but when he got a better look at her Sanji became love struck. Sanji was one of two people, the other being Luffy, who welcomed Robin into the crew.

Sanji treats Robin in much the same way he treats Nami, though while Nami treats his advances with anger and manipulation, Robin is polite and calm towards the cook. Sanji knows that Robin can actually take care of herself and as such does not worry as much about her safety while fighting foes as he does with Nami. His subservience for her extends to begging to lay his head on her bosom after the battle against the New Fish-man Pirates.

Sanji also will ask Robin for her advice and wisdom when dealing with a problem, Sanji even called Robin his "friend" to Wanze contrary to further claims that he was "born into this world to love women not be friends with them" to Ivankov. Sanji will also not stand Robin being insulted, brutally defeating Wanze and Jabra when they did so.

During the battle against Oars in the anime, while the crew attempted the "docking" technique where they all combine, similar to a "Mecha Robot", Sanji realized if Robin performed the "docking", he could possibly see up her skirt. While thinking this, Robin shot him a sharp deadly look. Sanji (like he does with Nami) gets blinded by his affection for Robin as such forgets the dangers around him like when he spotted Robin on Fish-Man Island and jump towards her only to be accidentally punched by both Luffy and Jinbe. When Sanji heard about Robin's past and how CP9 "used" her, Sanji called them "sick" and Sanji's advice to Usopp motivated him to save her from entering the Gates of Justice by using his sniper skills, thus ultimately saving Robin. Robin has also heard of the Vinsmokes but never thought Sanji would be connected to them. Sanji is also confident in Robin's abilities, telling Black Maria not to underestimate her.

Franky


When they first met on the Sea Train bound for Enies Lobby, Sanji kicked Franky in the face for what he did to Usopp, before learning how much the situation had changed since then. After Franky joins the crew, Sanji shows respect to Franky for his shipwright and engineering skills as Franky made him a great kitchen and dining room, though he gets irritated by Franky's habit of crying excessively after hearing sad stories. Sanji was actually quite hypocritical towards Franky calling him pervert for not wearing pants, but Franky took it as a compliment. Like Zoro, Franky will call Sanji "curly brow cook" but he is saying it as a nickname rather than as an insult.

Franky acknowledges that Sanji's strength is greater than his own, claiming that Sanji was one of the strongest fighters on the crew. Franky has shown some dislike towards Sanji's womanizing behavior, namely at Thriller Bark when Sanji showed more concern for Nami's safety rather than Usopp and Chopper after the three initially disappeared and later at Wano Country because of Sanji preparing his soba noodles to attract women rather than gathering samurai as he was originally supposed to do.

Brook
Sanji was one of the first members of the crew to meet Brook. He was shocked to see a walking and talking skeleton, and questioned Brook on how he came to be. Sanji could not understand why Brook seemed so constantly upbeat, telling the skeleton that his life was depressing, but the skeleton laughed him off. After Sanji learns about Brook's connection with Laboon, Sanji joined the rest of the crew in supporting Luffy's decision to recruit him into the crew. Sanji still gets irritated at Brook's immature character traits, including his burping and farting during dinner, and by his lame 'skull jokes'. He also once threatened to attack Brook when the latter laughed at the resemblance between Duval and Sanji's first, hand-drawn wanted poster.

However, Sanji has a lot of similarities to the un-dead musician. Both of them wear suits and act like gentlemen and fawn over Nami and Robin, making them the "pervert duo" of the Straw Hats. While they do fight over Nami and Robin's affection, the cook and the skeleton are good friends and were both (along with Kin'emon) very jealous of Momonosuke's "special attention" from the ladies. Brook looks up to Sanji and was in awe when the cook battled Doflamingo and was even prepared to aid him when Sanji was in trouble, but Sanji instead trusted Brook to look after Momonosuke, Nami, and Chopper. Brook was very depressed over the outcome of events in Zou and insisted on joining Luffy in the Sanji Retrieval Team as he felt responsible for Sanji's capture. Like Robin, Brook was aware of the Vinsmokes and never thought Sanji would be connected to such an infamous family. Along with the others, Brook showed great surprise that Sanji turned down Pudding.

Sanji appears to have a lot of trust in Brook's strength as he once entrusted Nami's safety to the skeleton while he went on to explore Claw City. Brook was also the only crewmate Sanji asked to accompany him when he had to deal with Pekoms and Capone Bege. Brook on his part has both high respect and a deep understanding of Sanji as a person as is seen by his saying to Big Mom that Sanji would give up his happiness to make sure the crew would survive, and he would respect Sanji's choice while making sure that he would not feel guilty if Luffy failed to return the cook to the crew. Brook was incredibly happy to hear Sanji again through the mirror shard, but also yelled insults at him like Chopper and Carrot. Brook deeply appreciates Sanji's cooking and was ecstatic to finally taste it again.

On a more humorous note, Brook was very jealous of Sanji after meeting Charlotte Pudding, Sanji's arranged bride and was smitten by Sanji's older sister.

Jinbe


While traveling to Arlong Park with Luffy and Yosaku in pursuit of Nami, Sanji was informed about Jinbe and the supposed agreement he made to obtain his position as one of the Seven Warlords of the Sea. The agreement stated that Jinbe had to let the Arlong Pirates rampage through the East Blue without opposing them. This apparently caused Sanji to develop a grudge against the fish-man captain due to the suffering and misery Jinbe's former crewmate Arlong caused to Nami and Cocoyasi Village. Sanji apparently had no reaction to Luffy's statement that Jinbe protected him during the Summit War of Marineford and its aftermath but later admitted that he believed that Jinbe was no different from Arlong.

The information that Jinbe had protected and cooperated with Luffy surprised him, but he still insisted that Jinbe's explanation for allowing Arlong to go to the East Blue would determine if he should be forgiven or hated. Despite Jinbe's story, Sanji was still angry with him but relented when Nami stated she forgave Jinbe. When Jinbe informed the Straw Hat Pirates that they cannot battle against the New Fish-Man Pirates because it would worsen relations between the two races, Sanji refuted this by insisting they had to rescue their comrades and therefore it was a reason to fight. Jinbe and Sanji later cooperated to defeat Wadatsumi in Gyoncorde Plaza. Sanji was also fine with Jinbe joining the crew, but the latter turned it down for the time being.

Jinbe later betrayed Big Mom to aid the crew and Sanji was surprised that Jinbe appeared to save Nami and Luffy. Jinbe later helped Sanji rescue his family from the Big Mom Pirates' assassination plot. Later on, Jinbe officially joined the crew but chose to stay behind to help his former crew. When Jinbe arrived at Wano to join the crew, Sanji was alongside them to celebrate his arrival.

Zeff
Owner Zeff!! Till my dying day, I shall never forget...everything you've done for this shitty lil' eggplant!!!



Sanji initially despised Zeff for attacking the cruise ship that Sanji was working on as a child. Sanji swore he would not die because he had to find the All Blue; Zeff, overhearing this comment, was greatly impacted by it, and when Sanji was swept overboard, Zeff jumped in after him. Sanji and Zeff were subsequently marooned on a rock for over 80 days, during which time both of them nearly starved to death. Sanji initially complained about Zeff's bag being bigger than the one he received, and secretly planned to leave Zeff to die if he managed to get a ship's attention. After weeks of eating nothing, Sanji decided he would take Zeff's rations, even if that meant killing him; however, he ultimately discovered that Zeff's portion of rations was actually a bag of treasure, and that Zeff and had eaten his own leg in order for Sanji to have all of the food. Overwhelmed, Sanji demanded to know the reason for the pirate's kindness, and Zeff simply replied that it was because he and Sanji shared the same dream. Zeff then confided to Sanji his idea of building a sea-going restaurant, if he ever got rescued. Sanji promised he would help Zeff run it, to which Zeff said he was too weak, but Sanji replied, "Then I'll become strong".

After their rescue, Zeff raised Sanji as his adopted son, teaching him about cooking as well as how to fight like a cook (meaning, without using his hands) and also the chivalry beliefs of never attacking a woman. Zeff admits to Sanji that he considers himself to be Sanji's parent and that it is his duty to make sure Sanji does not grow up to be a person he'll "come to despise", something that deeply moved Sanji. Sanji's sense of debt towards Zeff was Luffy's main obstacle in trying to recruit Sanji, and Zeff visibly had tears in his eyes when Sanji did finally leave the Baratie to join the Straw Hat Pirates. Despite their constant bickering and fighting and throwing insults while running the Baratie (with Sanji calling Zeff "shitty geezer" and Zeff calling Sanji "little eggplant"), Sanji has adopted a few of Zeff's personality traits notably the tendency to be hard on men that he knew and constantly insulting people. Sanji even considers Zeff as his true father, telling his biological father that "I have a father, but it is not you!"

When Sanji remained defiant against his family, Judge decided to show Sanji a picture of Zeff, stating Germa 66 knows where he is and are prepared to have him killed should Sanji continue to go against their demands. The revelation of the man who raised him being in danger caused Sanji to react in great shock as he recalled his memories with Zeff. Sanji's undying loyalty to Zeff is such that he would even sever ties with the Straw Hat Pirates with cruel and insulting words and indirectly broke his chivalry code by emotionally hurting Nami in order to protect the head chef as well as brutalizing his captain and best friend, Luffy.

Sanji's respect for Zeff is so great that he refused to allow his biological family to die at Big Mom's hands as he did not was to disappoint his "father". Sanji stated to his biological father who questioned his reason for saving them that he will not live a life where he is unable to look his "father" in the eye if he would stoop low enough to hold onto a petty grudge. Sanji verbally disowned Judge as his father and told him never to come near him or his crew as Judge solemnly promised to never interfere with Sanji's life or threaten the East Blue.

Baratie
Sanji had a habit of getting on everyone's nerves while at the Baratie. In particular, they resented the fact that he was the sous chef (and therefore their superior), despite being the youngest chef in the restaurant. They also found his habit of flirting with female customers annoying, while Patty, in particular, was disturbed by Sanji's frequent attacks against ungrateful customers. Despite this, Sanji's cooking was revered by all of the Baratie's cooks, and the entire cooking staff was upset by his departure. They have kept an eye on his progress through the Grand Line ever since and have used his former association with the Baratie to promote the restaurant every time his bounty is updated.

The Vinsmokes also threatened the inhabitants of Baratie, as when Sanji fought against his brothers, Niji sneered that their blood would be on his hands, causing Sanji to willingly allow Niji to strike him down.

Gin
Despite being enemies, Gin also considered Sanji as a friend because he showed him the only act of kindness he ever experienced. Gin was unable to bring himself to finish Sanji off and left on the vow that the pair would try and meet again on the Grand Line if it was ever possible. Sanji is the first person to ever show kindness to Gin, by giving him free food when the pirate was starved and penniless. As such, Gin ultimately cannot kill Sanji, despite his own reputation as a "Man-Demon", and Krieg's orders.

Nefertari Vivi
Like the first six of the Straw Hats, Sanji became good friends with Vivi. As with Nami and Robin, Sanji liked to pander to Vivi's every whim, but while Nami reacts with a combination of manipulation and annoyance to his advances, and Robin reacts with politeness, Vivi usually responded with confusion as to what he was doing or simply mistakes his infatuation for kindness. The only time Vivi acknowledged Sanj's pervertedness was when Sanji bought her dancer outfit. Vivi was embarrassed, explaining it was unpractical, but Sanji was too overexcited to care which led to Vivi claiming with exasperation that there was no getting through to him. Like the others, Sanji was saddened when she decided to remain in Arabasta threatening to kill Zoro when he told the crew to get over her absence.

Duval
Duval initially hated Sanji because he resembled Sanji's first, hand-drawn wanted poster, which resulted in his being incessantly hunted down by both bounty hunters and Marines. He was wounded in the back by someone who mistook him for Sanji. However, after a defeat during a fight with him, Duval became friends with Sanji because Sanji reshaped his face to make him look handsome. The downside is that Duval's love for his new handsome face, and his reference to Sanji as "young master", gets on Sanji's nerves. Despite preferring not to see him or his men again after their original parting, Sanji decided to call in the Flying Fish Riders when Camie was kidnapped and sent to a Human Auction House, aware that their experience in the Human Auction Business was necessary to locate Camie in time to save her.

Kamabakka Kingdom


Sanji also developed a friendly (of sorts) relationship with the entire populace of Kamabakka Kingdom, not unlike Luffy's own with the Kuja of Amazon Lily, after being sent there against his will by Bartholomew Kuma. Ironically, this bond initially started out as "hell" for Sanji, but later improved overtime as he assimilated (to his chagrin) with their lifestyle. This relationship further bettered upon meeting their then-newly freed leader, Emporio Ivankov, who aided Luffy during the Summit War two years ago. Upon receiving Luffy's disguised message for his crew to lay low and strengthen for the next two years, Sanji spent the period fighting the 99 Okama Kenpo masters to retrieve their recipes for Attack Cuisine. Having succeeded in his task, Sanji was granted a lift back to the Sabaody Archipelago. In response to their pleas for him to visit them again, he gave them the finger and proclaimed he would never return, though he also asked them to thank Ivankov on his behalf. Due to his time on the island, as well as the trauma he experienced from his encounter with Splash and Splatter, he has developed a huge aversion to Okama.

Shirahoshi


When exploring Fish-Man Island, Sanji eventually met Princess Shirahoshi. Despite Chopper's pleas against this due to him losing blood at the sight of other mermaids he was instantly turned to stone upon gazing at her. Afterwards Sanji showed to adjust well to her presence, reacting the same way to her as he usually does around Nami and Robin. Shirahoshi seemed unsure and afraid towards his affections, but, because she was good friends with Luffy, she trusted him well.

During the battle with the New Fish-Man Pirates, Sanji was quick to save her as she thanked him for his actions. As the Straw Hats were preparing to leave Fish-Man Island, he was one of the members who promised to take her to the surface when they see her again.

Viola
When exploring the island of Dressrosa, upon in pursuit of a fairy who took Zoro's Shusui, Sanji met a flamenco dancer named Viola who had a grudge on a certain sniper. Naturally, Sanji offers his assistance without hesitation. Not long after that, it was revealed that Violet was one of Doflamingo's underlings, but in spite of being beaten up, Sanji believed that she was serving against her will, and still wanted to help her. She does not believe him at first but realizes that he is being sincere after she uses her Devil Fruit abilities to look into his mind. Consequently, she betrays her underlings and urges Sanji to leave Dressrosa, using her powers to show him that he fell into a trap and giving him a Den Den Mushi to warn Law, and also gives him a map to get to the hidden SAD factory.

Mink Tribe
Due to his group's efforts in saving the Mink Tribe after they were devastated by an attack from Jack, Sanji and his crew are considered as saviors to the minks. Therefore, they formed a harmonic relationship. Inuarashi, Nekomamushi, Pedro, and Pekoms feel strongly indebted to Sanji, and Wanda even tried to chase after Capone Bege when the gangster took Sanji away from his crew. While staying with the Mink Tribe, Sanji was greatly taken with the female minks.

Carrot
Carrot also expressed her fondness for Sanji during a conversation with Charlotte Pudding after the latter claimed to be in love with the cook. When Sanji felt guilty after he discovered Pedro had sacrificed himself to ensure their escape, but Carrot (patting Sanji’s head) refused to let him feel that way, saying it was Pedro's decision to come to Whole Cake Island. While saying this, Carrot broke down in tears, prompting Sanji to give her a hug. Carrot also loved Sanji's cooking to the point she gluttonously cheered after having the chance to taste his cooking again.

Toko
Toko was one of Sanji's customers at his soba stand in the Flower Capital. When Kuni knocked her soba noodles out of Toko's hands, Sanji kicked his head into the ground for wasting food and happily gave the last bowl to Toko. When Toko complimented his cooking, Sanji found her mannerism amusing. Later, when Toko trespassed into her father's execution, Sanji recognized her and expressed his concern. When Orochi shot at Toko, Sanji came to rescue her along with Zoro. After Zoro handed Toko over to Sanji, he further protected her while being attacked by X Drake before he gave Toko to Usopp so he could look after her.

Family
Spoiled brats who don't appreciate a warm meal... Men who dare raise their hands against a woman... Royals who treat the lives of their subordinates as nothing more than expendable pawns... Everything you do... Everything you stand for... runs counter to my ideals!!

Sanji has an immensely strained relationship with his family, the Vinsmoke Family, and has been estranged from them since he was 8. Their royal pride and singular focus on strength and warfare conflict with his own dream and his chosen profession as a chef. His brothers used to brutally bully him because of "weakness" and his childhood tendency to cook for others, and they followed their father's example in calling Sanji a disgrace to the family name. At the age of 8, after being imprisoned by his father for 6 months, he chose to flee the Germa Kingdom despite being told that he would never survive alone on the high seas, indicating that he preferred to risk death rather than remaining with his family. After learning of his arranged wedding, Sanji resolved to return to the Germa Kingdom, in part, because he held out hope that his family may have changed or improved since he last saw them; however, these hopes were in vain as Sanji remarked that they have only gotten worse over the years.

Despite his issues with his father and brothers, Sanji loved his deceased mother, so much so that he tried to carry on her legacy of caring for the weak. He also cares greatly for his elder sister Reiju, who was the only other person to show him kindness and the one who helped him to escape as a child. Even after a decade of estrangement, when Sanji returned with a vast improvement in physical strength, Reiju remains the only living member of their family to acknowledge him in a positive way.

Due to both conflicting ideals and being disinherited, Sanji shows complete disinterest in the Vinsmoke Family's political affairs. Even as a child, he chose exile on the high seas over remaining a prince in the kingdom. As an adult, he considers the family's actions (and their pride in those actions) to be "insane". Later, as the rest of the family conversed about their political and military standpoints, Sanji simply ate quietly. While he was deeply affected in his childhood by being considered the family failure, his time away from them has helped him to see them more objectively. During the same meal, when his brother Niji told him that he brought shame to their family name, Sanji declared that being affiliated with it brought shame to him. He also confided to Pudding that, despite it giving him royal status, he had never once felt any joy in being born a Vinsmoke.

Sanji has only once identified as a member of the family. However, it was merely an act put on in response to the pressures imposed on him by his family, including their holding his father figure hostage, and to prevent harm coming to Luffy and Nami. The whole incident caused Sanji great distress, and while it satisfied his father, his brothers resumed tormenting him immediately after seeing his anguish at speaking down to his crew.

After learning of Big Mom's assassination plot against his family, Sanji confided to his sister that, while he hates the rest of their family for all the pain and suffering, they put him through, he does not want her to die, leaving her touched. In a later talk with Luffy, Sanji stated that, while he feels no obligation to save his family from their fate, he did not have it in him to leave them to die at Big Mom's hand and wanted to find a way to save them. During the Tea Party, the Big Mom Pirates showed their treachery and were prepared to execute his family while Sanji went out of his way to rescue them which he was able to do. The family was very shocked by the lengths Sanji would go through to save them especially Reiju and Judge.

After learning of Sanji's reasons for saving them, which was to overcome his childhood grudge for Zeff's sake, the Vinsmoke Family decided to clear their debt to Sanji by fighting off the Big Mom Pirates to give his friends and allies an opening to escape.

Afterwards, Sanji wanted to distance himself from his family again as he told his crew not to mention them. Though the family gave Sanji his own Raid Suit, Sanji does not want anything from his family and considered it an insult. Ironically, Sanji later learned that his Raid Suit had helped fulfill his lost dream, which was to have the power to make himself invisible. He was further dismayed to see that despite his wishes, he is still considered a Vinsmoke as his new bounty poster included his family name. When Drake mentioned of the Vinsmoke to Sanji, Sanji angrily replied to him to never call him by his family name.

Vinsmoke Judge
My father would have been saddened. He would be appalled at the kind of man that would hold on to a petty grudge and ridicule the death of their own blood relatives. I won't live a life where I am not able to face that person. 13 years ago, the Vinsmoke Sanji that ran away from Germa died on the seas, just like you wanted. Therefore recognize this! You are not my father, Vinsmoke Judge!"

Sanji has a strong hatred toward his biological father due to his neglect for him. Since he did not possess the enhancements, Judge tried to give him, he was treated with disdain due to his lack of progress and weakness. Judge allowed Sanji's brothers to beat him up and he eventually locked Sanji in a cell. However, Judge allowed Sanji to be fed and even allowed him to escape when given the opportunity, on the condition that Sanji not identify himself as his son. Sanji was brought to tears by the disdain his father treated him with, and after he met Zeff, who treated Sanji like a son, he had no problem with disowning Judge and viewing Zeff as his real father.



After Sanji left the Vinsmokes, Judge later viewed him to be of use as a sacrifice to marry off to the Big Mom Pirates in order to form an alliance with them, and when the two reunited 13 years later, Judge's expectations for Sanji to follow his orders were met with disdain. He hypocritically berated Sanji for not being obedient, despite still not considering Sanji as a son, and resorted to physical threats to get him to comply with the arranged marriage. The two battled with Judge being surprised by Sanji's new strength before using underhanded moves to defeat him. After this, Sanji remarked that he returned to see if Judge had changed but was dismayed to see that he has gotten worse since the last time the two met each other. In response, Judge retorted he never saw Sanji as his son and only sought him out to further his goal of retaking the North Blue. He even had Reiju handcuff Sanji with what appeared to be exploding wristlets.

When Sanji showed no intention of ever caring for Judge's wishes and resisted heavily, he was forced into complying due to the threats.

However, when he discovered that Judge and the rest of his family were to be killed at the wedding ceremony, Sanji admitted that he did not have it in him to abandon them. At the wedding, when the Big Mom pirates prepared to execute his captive family, Sanji surprised his father by freeing him and his siblings from their clutches.



After he had rescued them, Judge questioned Sanji on why he would save them due to the pain they put him through, even voicing how easy it would be to allow them to die. In response, Sanji told him that it was to honor his "true father" before he verbally disowned Judge as his father again. Having appeared to see the pain he caused Sanji and somewhat humbled from Big Mom's betrayal, a solemn Judge accepted this decision, and the Vinsmoke patriarch then swore to never interfere with Sanji's life ever again and promised not to go near the East Blue. Judge then offered to hold off the Big Mom Pirates due to not wanting to be indebted to a "failure", something Sanji understood and declared as his resolve.

Judge once again came to Sanji's aid at Cacao Island. While asking Luffy why he risked his life for Sanji, Judge still referred to Sanji as Germa's failure.

Vinsmoke Sora
You are definitely not a failure, the child whom Mother risked her life to protect from Father's corruption, the boy who was born bearing emotion. That is you, Sanji which is why...you are more kind than anyone else!!!

While she was pregnant with Sanji and his brothers, Sanji's mother took a drug to counteract the effects of the genetic modification surgery Judge eventually forced her to undergo. While the drug made her weaker, she had no regrets, as the drug ensured that Sanji, at least, grew to be a human with emotion. As a result, Sora was extremely overjoyed every time Sanji showed kindness, and she doted on him for his compassion. Unknown to Sanji, Sora often shared her happiness at Sanji's emotional growth with his elder sister, Reiju. After Sanji told her to get well soon, she burst into tears, stating that Sanji is the best kid in the world.

Sanji, in return, deeply cared for his mother. He once brought food for her and, even though it was ruined, she still ate it and declared it to be delicious. After her death, and against Judge's orders, Sanji carried out his late mother's will by becoming a chef to honor her memory. When he learns of the reason for her premature death, Sanji is initially horrified and begins to blame himself, but Reiju reassures him that their mother was happy from the bottom of her heart.

Vinsmoke Reiju


Out of all his siblings, Sanji has a better relationship with his elder sister, as while she did partake in laughing at him as a child, she only did so to avoid being bullied herself and tended to his wounds in secret. She felt enough empathy for him to free him from his imprisonment and even tearfully told him that he would meet people who would treat him better.

However, Sanji still showed disdain for Reiju when they reunited as adults due to her role in dragging him back to the family, and her attempts to show him the benefits of a royal life despite knowing what he went through as a child. While watching him duel their father, she would be amazed with the strength and durability Sanji has gained since their childhood. Following his defeat, she would tend to Sanji's wounds while voicing her surprise that he was the previous weak child that she once knew.



Though Sanji did not think much of her, Reiju treated his wounds after his brothers beat him once again and even questioned his choice to return. After Reiju was wounded by Charlotte Pudding, Sanji felt obliged to tell his sister the truth about the Big Mom's plan to assassinate the Vinsmokes. When Reiju told him to leave her and the family, Sanji was vocally against the idea as that meant she would die, showing that in spite of everything, he truly does care for his sister. In response, a touched Reiju expressed that she was proud of his empathy, telling him the truth of their mother's death and alleviating his thoughts of guilt for her passing.

Despite his sister's pleas, Sanji refused to leave her to die and worked with his crew to save her. When it briefly seemed that Sanji would not succeed in rescuing his family at the tea party, he called out to his sister and Reiju again expressed her pride in him for his empathy. Due to Luffy's actions, Sanji was able to reach her and free her and the rest of his family. She later expressed a smile after Sanji verbally disowned Judge again after he questioned the latter's reason of liberating them from Big Mom's clutches. As the Vinsmokes fought off the Big Mom Pirates, Sanji and Luffy quickly came to Reiju's aid when Big Mom focused her attacks on her.

At Cacao Island, Reiju aided Sanji in escaping with his captain.

Brothers


Sanji holds a great hatred toward his fellow quadruplet brothers, Ichiji, Niji, and Yonji, who were born with genetic enhancements while he was not, thus taking away their empathy. Since he fell behind them, he was repeatedly tormented and bullied due to his weakness, with his brothers taking joy in exerting their strength on him. When Sanji was given a fake funeral, they were fine and even happy with his supposed death. After learning he was still alive, they routinely beat him up in the dungeon while calling him a failure, which was a factor in why he ran away from the family.



When they reunited as adults, Yonji had expected Sanji to still be as weak as he used to be and tried bossing him around, only to be met with a rude awakening as Sanji showcased his improved strength by effortlessly breaking his face. Sanji treated all three of his brothers with bitterness, berating their poor manners and now having the proper strength to fight back, he is not afraid to physically attack them. The brothers were surprised at his improvement but were more than willing to beat him up once again in response, as they happily held Zeff under threat in order to render Sanji weak. Ichiji berated his younger brother for not acting like a proper royal, and Niji got revenge on Sanji standing up to him by viciously beating a cook Sanji had defended, causing Sanji to become extremely enraged at Niji and attack him on first sight. When Sanji cried after being forced to distance himself from Luffy, his brothers all laughed at his pain.



Despite his utter disdain for them, Sanji decided to save his brothers along with his father and sister when he discovered they were under threat of assassination by the Big Mom Pirates in order to grow out of his childhood grudge. His brothers were surprised at him rescuing them and saved his allies as repayment. They seemed to have no reaction to his actions and remained silent when Sanji officially disowned their father again. Even though they did not thank Sanji for saving them, they showed their gratitude by willingly assisting Sanji and his friends in escaping the wedding venue without any complaints. At Cacao Island, Sanji's brothers came to his aid once again though claimed that they were seeking payback against the Big Mom Pirates for their deception. They went out of their way to ensure Sanji escaped safely by bringing down specific enemies who tried to thwart his escape.

Afterwards, Sanji was angry to discover that Niji gave him a Raid Suit, which he took as both an insult to his strength and an unwelcome reminder of his Vinsmoke heritage. When he started to develop the same modified abilities as his brothers, he became annoyed and enraged as he did not want to become anything like them, even though his new augmented body is the very reason he survived Queen's attacks.

Marines
Like all the Straw Hats, he is wanted by the Marines. The Marines as they do with all pirates utterly hate Sanji, calling him by his moniker "Black Leg" though before his bounty, Zoro joked they see him as just "Pirate A". Sanji could not care less about the Marines, beating aside trained marines without hesitation.

Sanji earned a bounty as a result of his piracy. His first bounty poster featured a rather crude image of his face, due to the Marines being unable to get a proper snapshot, much to Sanji's chagrin. The second bounty poster was updated to reflect his true image, although it now features his unique bounty condition ("Only Alive"). After Sanji is revealed to be a member of the Vinsmoke Family, it was revealed that the bounty condition was set by the Marines at the instigation of his father.

After he returned to his crew, the bounty condition changed back to "Dead or Alive", since the Germa Kingdom has lost its connection with the World Government. The poster also included his full name "Vinsmoke Sanji", meaning that the Marines are now aware of his heritage. Sanji was once again dismayed by his poster, as he despised the name "Vinsmoke".

Fullbody


Fullbody especially has a personal vendetta against him for what happened at the Baratie. However, this has never been taken seriously; Sanji ruins his date with a woman named Moodie when he corrects Fullbody on the type of wine he and his date were consuming. Fullbody decides to put a fly (Batchee) in his own soup to ruin the restaurant's reputation and to get back at Sanji. However, Sanji's continuously smug attitude leads Fullbody to smash the table he is sitting at, prompting a fight with Sanji. He is later shown to have lost horribly, being held dangling from his neck and lectured about wasting food. Fullbody, with his ego in tatters, is later shown fleeing the Baratie. Fullbody swore revenge on that "crazy cook" but his later encounters with the cook have always ended with him fleeing in terror.

Smoker
Sanji dislikes Smoker, unflattering dubbing him the "Smoke freak" in Arabasta. After nearly getting captured in Loguetown, Sanji is not anxious to fight Smoker in combat and was glad when Luffy distracted him so he could beat Smoker's troops without trouble. When Smoker ungratefully yelled at the crew when they pulled him out of the water at Rain Dinners, Sanji stated "See, this is what you get for helping a Marine" but was legitimately surprised when Smoker let them go free.

Tashigi
The only exception to Sanji's Marine dislike is the beautiful Tashigi, who he saved from Vergo despite their warring factions and Sanji showed some comradery with the G-5 Marines, who felt indebted to him. Sanji even ordered them around. Sanji only showed jealously when he saw Zoro carrying Tashigi around after they fought Monet but was willingly to let Zoro look after her and told the G-5 Marines that she was in good hands.

G-5 Marines
Sanji became acquainted with the G-5 marines. They seem to respect Sanji quite a lot, especially because he saved Tashigi from the "fake" Vergo. Also, much to Zoro’s surprise, they obey his orders to the point that they let him be in command during the fight against Caesar Clown and his subordinates. They refer to him as bro.

Enemies
Due to Sanji's principles, anyone who treats women and food in a disrespectful manner will earn Sanji's wrath. As revealed during his initial encounter with Duval, Sanji supposedly has many people who bear grudges against him from his time at the Baratie.

Jabra
Jabra became Sanji's enemy during the crew's siege on Enies Lobby to save Robin. The then-CP9 agent earned Sanji's wrath after he wounded his friend Usopp and they engaged in battle. Jabra proved to be a formidable opponent for Sanji with his superhuman strength, claws, and his ability to use the Tekkai technique while still being able to move around. It was only after Sanji managed to develop a new technique that could scorch and critically injure his opponent simultaneously that he was finally able to defeat Jabra.

Absalom
Sanji considered Absalom his arch-nemesis and is the only villain to make Sanji angrier than he's ever been in the series (until he met his family again). First, the Invisible man crept on board the Sunny and molested Robin and knocked Sanji about, then accosted Nami while she was bathing and stalked her relentlessly through Thriller Bark only to blocked by Sanji's own shadow getting Absalom angry. And when Absalom finally stole Nami from Usopp and Chopper, Sanji heard the news and burst into flames of angry swearing he will kill the invisible man and rushed off the save Nami. Interrupting the marriage and brutally beating Absalom into a pulp, Sanji also revealed he hated Absalom because he ate the Suke Suke no Mi since Sanji dreamed of using it to peep on girls too. Absalom also hates Sanji for keeping Nami from him and "touching his bride", after seeing the cheap tactics of the invisible man, Sanji stated he no longer desired the fruit (since he could just peep on his own). Sanji then imprinted Absalom on a stone wall, thereby weakening him so much that Nami would later finish him off with one attack.

Big Mom Pirates
As a member of the Straw Hats, Sanji is an enemy of the Big Mom Pirates. At Dressrosa, Sanji personally asked for permission to return fire on their ship. After Sanji was taken from Zou, Tamago tried to convince Sanji to go through with the wedding and join the crew, but Sanji refused. Tamago even provided explosive wristlets for Judge to use to keep Sanji in line. When Charlotte Pudding held his sister captive, she revealed her true nature as well as her family's plans to kill his own family. Sanji was dismayed at these revelations and nearly resigned himself to being killed. However, after Bobbin tried to steal food he made for his friends, Sanji attacked him and fled to regroup with his crew.

During the Tea Party, the Big Mom Pirates were prepared to slaughter Sanji and his family, but when Pudding faltered after Sanji complimented her, their plans went awry. Pudding's brother Charlotte Katakuri tried to kill Sanji himself when he knew he would dodge a shot from the priest, but that attempt failed as Sanji dodged the shot as well and glared at his surprised would-be assassin. He later fought with Charlotte Daifuku, who decided to take it upon himself to kill Sanji after Pudding's failure. After the Big Mom Pirates held his family at gunpoint, Sanji tried to save them, but Daifuku held him at bay. However, after Luffy caused Big Mom to scream, Sanji managed to free his family from their clutches. Sanji later attacked Charlotte Oven to protect Charlotte Chiffon since she was helpful to his crew. Sanji fought through dozens of their forces to protect a weakened Luffy from their vengeful nature after Katakuri was defeated.

Sanji was nearly overwhelmed, but his siblings came to his aid, and he escaped the enemy crew.

Charlotte Linlin
When first hearing about how Big Mom was prepared to destroy Fish-Man Island over lack of a candy tribute, Sanji was vocal about his disagreement about the Emperor's ruthlessness, alongside Luffy and Zoro. At first agreeing with Zoro that Big Mom is not being manly for being impatient, Sanji changed his opinion slightly when hearing that Big Mom is a woman, fantasizing her as an attractive redhead.

As a result of his central role in sealing the political alliance agreed between herself and Sanji's father, Big Mom treats Sanji as a figure of immense value. She is prone to thinking of Sanji with reference to his Vinsmoke heritage, referring to him primarily as "the Germa boy" and ordering her children and subordinates to ensure that no harm comes to him. She and her children also hold his royal heritage in great respect, especially because it is that of the powerful Germa Kingdom; indeed, Charlotte Cracker references this status to try to convince Luffy that Sanji would have no interest in returning to a "lowly pirate crew".

Beyond his political value, however, Big Mom respects Sanji's cooking skills and experience, and his pirating exploits with the Straw Hat crew. She had Baron Tamago extend Sanji a position in her crew if he cooperated with the wedding, but Sanji immediately refused the offer. Sanji later talked to Big Mom in person and was surprised and grateful to hear that Big Mom would allow his friends to be spared as long as he agreed to marry Pudding. However, he later heard about Big Mom's plan to kill him and his family, with Big Mom gleefully plotting for Pudding to shoot him between the eyes. Having learned this, Sanji nearly resigned himself to being killed, but immediately regained his senses and rushed to regroup with his captain to ruin the Tea Party and save his family from her.

While discussing with Bege about the assassination plot on Big Mom, Sanji recognized her as a powerful threat and even pointed out how slim the chance of taking her down.

At the wedding, Sanji foiled Big Mom's plans by surviving the assassination attempt on his life. With the help of his crew, he was able to save and free his family from her clutches. When Big Mom attempted to kill his sister Reiju, Sanji and Luffy intercepted her.

After Sanji and his allies were routed by the Big Mom Pirates, Linlin prepared to execute them before the Tamatebako dropped to the base of the Whole Cake Chateau and exploded, causing the castle to collapse.

Despite her attempts to kill him, Sanji strongly opposed to Bege's intention to sabotage Big Mom's substitute wedding cake with poison or explosives. Sanji was also confident that his cake would greatly please the Emperor with its delicious flavor.

Kurozumi Orochi
As an ally of the Kozuki Family, Sanji is an enemy of Orochi. Sanji was deeply shocked when Kin'emon explained about Orochi's atrocities in killing Oden. Later, he personally developed an intense hatred for the shogun when he learned from Shinobu about how Orochi fed his impoverished citizens the faulty SMILE fruits to rob them of their emotions, forcing them to only smile, which stood against Sanji's ideals of food. Alongside Zoro, he openly stood up against Orochi by defending Toko.

X Drake
Because of Sanji's transgression against the Kyoshiro Family, Drake was one of two people sent to punish him. After Page One failed to kill Sanji, Drake continued with his mission to hunt down Sanji and was relentless in attacking him at Rasetsu Town. When having their one-on-one conflict, Drake was surprised to learn he was a Vinsmoke and that made him angry for being referred as one.

Queen


Sanji met Queen during his crew's attack on Onigashima and soon found out that he was once a research partner of his hated father in a group called MADS. Sanji quickly took a disliking to the All-Star due to his attack on his crewmate Chopper and for reminding him of his heritage. During their fight, Queen assumed that Sanji’s flaming kick was some sort of genetic enhancement done by Judge because he heard that Judge did body modifications on his children. Sanji denied this, but Queen scoffed at him, claiming that normal humans do not control fire like Lunarians. Queen became determined to prove his superiority in battle using his strength and scientific brilliance. As their fight continued, Sanji became increasingly annoyed by Queen's desire to see him use his Raid Suit again and by the fact that he seems to be awakening the enhancements of his brothers by fighting the All-Star.

Sanji's hatred for Queen continued to grow as he realized he could replicate the abilities of his brothers, who he deeply hated, and when Queen told him that he wanted him to wear his Raid Suit so that he could beat him and therefore prove to Judge that he was the superior scientist. It reached its pinnacle when he realized that he attacked an innocent geisha when he was invisible, which caused Sanji to doubt himself and his compassion, leading him to bash him repeatedly with his new Ifrit Jambe techniques finally defeating the deranged scientist and sent his unconscious body flying away from Onigashima.

Germa Kingdom
Like with the members of the Vinsmoke Family, the Germa soldiers cared for Sanji and supported him in training. They would go to help him when he nearly drowned and stopped Niji from beating him any further. One of the soldiers even tried to help him when he was going out in a storm to visit his mother.

However, they were obliged to do what Judge commands them to do, as some were ordered to place an iron mask on him without hesitation or any defiance. As Judge announced Sanji's "death", the onlookers were deeply sadden.

Upon Sanji returning, the soldiers were excited for his return. They cheered for him and Judge when they were about to battle. They even acknowledged Sanji's strength in spite of not wearing a Raid Suit. However, like before when he was child, they were once again obliged with Judge's orders to be used as human shields when Sanji was about to attack.

Sanji was deeply disgusted about Judge's philosophy about the soldiers of Germa 66 being as tools for war but upon hearing about the Vinsmoke's cloning technology and that the soldiers are nothing more than clones, Sanji was deeply mortified.

In spite of him not caring for the soldiers and humble about his royal status, he does not show any disdain towards the servants. Sanji saved Cosette from getting hit by a plate of food after he and Niji got into an argument about their different qualms about food. He even ate a piece of it after it had fallen to the floor in spite of Cosette insisting that she would clean it up and let him not eat it off the floor, but she blushed once Sanji commented on how tasty the food was. After Sanji found Cosette unconsciously beaten, he yelled for a doctor and went after Niji in anger.

Bentham


Bentham was the Baroque Works agent Mr. 2 at the time Sanji and the rest of the crew met him, making him an enemy. Like the rest of the Straw Hats Sanji saw his shapeshifting powers as a serious threat. During Operation Utopia Sanji and Bentham fought a fierce battle; Sanji found Bentham to be a difficult opponent to fight between Bentham distracting his lustful side by taking on Nami's form and Bentham's unorthodox fighting techniques, however Sanji found a weak point to exploit and narrowly defeated Mr. 2. When Bentham showed the Straw Hats he was no longer their enemy by sacrificing himself so they could escape Hina's marine fleet Sanji actually cried, showing a deep sense in gratitude.

Bartholomew Kuma
Sanji greatly resents Bartholomew Kuma who sent him to an Okama island for 2 years while sending Luffy to Amazon Lily. Out of the crew, he is the only one who is still bitter about the separation, in spite of learning the truth about Kuma, in spite of Kuma's reasons for it, and even in spite of the dramatic increase in ability it provided.

Charlotte Pudding


Sanji was arranged to be married to Charlotte Pudding, Big Mom's 35th daughter. Already smitten after receiving her photograph, he became attracted to her during their first meeting because of her beauty and their mutual love of cooking. Despite expressing a desire to marry her, however, Sanji maintained his refusal and turned her down because he did not want to be forced to leave his crew. When Pudding first encountered the Sanji retrieval team on Cacao Island, she recounted her first meeting with Sanji to the team in a flustered and embarrassed way, leading Nami to ask whether Pudding had already fallen in love with him. After seeing the crew's resolve to get Sanji back, Pudding promised to help reunite the crew with Sanji, drawing them a map that would lead them to the treacherous Seducing Woods.

The two met again at Whole Cake Chateau, where they conversed in secret. Pudding informed Sanji that she had encountered Luffy and others and offers to take the blame if Sanji wanted to run from the invitation. In response, Sanji revealed to her both the exploding wristlets and the injuries he sustained from his brothers, before explaining his tragic history with his family (which ended when he met his father figure and his crew). When Pudding broke down in tears, bemoaning that her own mother was responsible for his grief, he comforted her by stating she was the only hope he had in this dark time. He told Pudding if she accepted, they should go through with the marriage. Sanji followed this up by making an agreement with Big Mom, whereby he promised to marry Pudding in exchange for the release of his friends, before deciding to give in to his love crazy-nature and claim he was in love with his "fiancée".



The day before the wedding ceremony, Pudding went to speak to Luffy and Nami in the Prison Library. She informed them that Sanji had proposed to her, shocking both of them, before assuring them that she would not be marrying him. Instead, to their even greater horror, she revealed her plan to assassinate Sanji at the ceremony. Unbeknownst to Pudding, Sanji soon learned of Pudding's true (sadistic) nature while she was holding Reiju prisoner, including how she had tricked him into believing she was a kind woman who genuinely cared about him. The betrayal leaves Sanji silently heartbroken. Despite his strong-willed nature, Sanji was soon brought to tears and was left silently crying in the rain. Pudding began to cruelly mock him for his belief in her as she explained her plans to kill him at their wedding. Pudding also called his swollen face "ugly" and cruelly referred to him as a "failure" like his brothers did as well as mocking his proposal and even considered him unworthy to be a proper prince.

While conversing with Reiju and explaining what really happened to her, Sanji expressed anger that he fell for Pudding's trickery, calling his attempts to save his crew a joke. On the day of the wedding, he was uncomfortable around her (given that he is now aware of her true nature) and had very conflicting thoughts as to her act being real as he struggled with trying to keep himself focused. However, despite knowing Pudding's murderous intentions and how she sadistically mocked him before, Sanji is still irresistibly infatuated by her charms and beauty to the point he had another extreme nosebleed that caused him to fly and crash into a wall much to Pudding's secret disgust. When he and Pudding approached the main venue, Sanji was shown with a face of joy.

During the exchange of vows at the wedding altar, Sanji internally continued to keep his wits to stay alive while Pudding was ready to go through with her mother's plan. However, after Sanji called her third eye beautiful as he noticed goodness when he first looked at it up close, she broke down in tears due to him being the first person to say anything nice about her third eye.

Despite previous ill-will from Pudding, Sanji nevertheless rescued her from the falling wedding cake.

Though he saved her, Pudding furiously attempted to shoot Sanji while admitting that she had deceived him like she did to countless other people. He then caused her to waver by asking if she lied to herself as well. Even after her attempt on his life, he saved her once more when her brother Charlotte Daifuku attacked and showed concern for her after he ruthlessly slapped her away.



Sometime after the Straw Hats escaped from the Whole Cake Chateau, Pudding developed an intense, romantic fixation on Sanji after being touched by his kindness. In stark contrast to her behavior towards him previously, she can no longer interact with him without blushing wildly and panicking. Motivated by her newfound feelings, she even turned on her mother for his sake and began to actively assist the Sanji Retrieval Team in escaping Whole Cake Island. However, due to also suddenly developing an erratic personality disorder, her moods switched rapidly from outwardly expressing both love and disdain for Sanji, sometimes at the same time. Despite this, however, she continued to assist Sanji and the Straw Hats even as she lapsed into her "evil Pudding" persona. Sanji himself appeared curious about Pudding's erratic behavior, but otherwise remained friendly and loving towards her. As she continued to act belligerently towards him, he simply ignored her protests and thanked her while also complimenting her beauty yet again, causing her to become flustered.



Later, they are shown to cooperate well with each other while baking a new cake for Big Mom, with Pudding diligently taking instructions from Sanji. Pudding showed admiration for Sanji and becomes ecstatic whenever he does something amazing such as creating a special ingredient that made a chef faint with bliss, saving Chiffon from Oven, and lifting the carriage holding the wedding cake to Bege's ship with a kick. In these moments, her reactions are no different from Sanji's reactions to her beauty as she now gets nosebleeds and is left amazed by his abilities. Even though Pudding occasionally goes into her "evil" persona and speaks ill towards him, Sanji continues paying no mind to it. After leaving the cake in Bege's hands, Pudding took Sanji back to the Sunny so he could reunite with his crew and later back to Cacao Island so he could help his captain. Sanji graciously thanked Pudding for her help, but Pudding became extremely flustered, wanting to avoid being mistaken as a married couple. While waiting for Luffy on Cacao Island, Sanji decided to part ways with Pudding once Luffy returned and once again thanked Pudding for her help. Pudding wanted to apologize to Sanji for her deception but could not bring herself to do it. Sanji also told her that he was glad that she was his fiancée, causing her to become emotional again. Pudding made one last request to Sanji and kissed him, which delighted him. However, she used her Devil Fruit ability to remove the moment from his memory before leaving him without saying another word.

Vito
Sanji's first encounter with Vito was hostile, as the latter held Nami and Chopper hostage while telling Sanji the repercussions of refusing to attend Big Mom's Tea Party. He also conveyed to Sanji Big Mom's personal threat to take retribution against someone Sanji loved if he dishonored her invitation.

Vito later becomes markedly more friendly to Sanji, revealing that he is an enormous fan of the fictional comic strip, Sora, Warrior of the Sea, and that he idolized its villain group, Germa 66. Because of this reverence, he was excited and pleased to meet Sanji, a member of the family that commands the Germa, and constantly tries to engage Sanji in a conversation about them. Sanji, by contrast, finds Vito's enthusiasm about his family irritating and attempts to shake Vito off whenever the latter follows him around.

Despite Sanji's irritation at him, Sanji's heritage as a Germa prince led Vito to help Sanji by ambushing and shoot down Bobbin when the latter chased after the Straw Hat cook. Vito explained later to his captain that he did so because Germa 66 are his idols. He expressed great excitement in meeting Sanji again when the latter arrived at the Fire Tank Pirates' hideout calling him his hero. He was also impressed with Sanji's strength when he used a kick to lift a large carriage holding a group of chefs and a massive wedding cake onto the deck of Bege's ship.

Carmen
Carmen admire Sanji's undying passion to seek out his dream since she saw him Sanji talking to the chefs about his dream to find the All Blue when she walked by the Orbit's kitchen whet they were young. In Loguetown, she challenges him to a cooking contest, where Carmen ends up in second place behind Sanji. Also, as he does with all the girls, Sanji constantly flirts with Carmen.

Banban
When he arrived at Banban's small floating restaurant, Sanji noticed that Banban was fast asleep, so he decided to prepare something himself. When Banban woke up, immediately recognized Sanji's way of handling the carving knife, for he knew Sanji's mentor, "Red-Leg" Zeff. Before they left, he insisted that Sanji taste some of his cooking. Sanji was amazed by the flavor, but could not figure out how the old man made it. Moments later, Sanji came back and told him that he had realized he used a the salt created by Aqua Laguna. Hearing Sanji say this, Banban laughed at told him that he was correct, and told him to bring him to a rooftop, where he explained that when the Aqua Laguna covers the buildings with seawater and that, in the following sunny days, particularly tasty residual salt would be left on the rooftops.
