The alliance include three crews from the Worst Generation, the Kozuki Family, the Mink Tribe from Mokomo Dukedom, numerous allies from Wano Country, a marine rear admiral undercover as a pirate, and a Super Rookie. The Pirates have a combined bounty of at least 4,763,000,600, the Kozuki Family is a noble family in Wano Country, leading a legendary group of powerful Samurai, and the minks are all born warriors with the ability to produce electric shocks known as Electro.
Additionally, during the raid, the alliance gained three former members the crews of two emperors: Marco and Izo from the Whitebeard Pirates and Yamato from the Beasts Pirates. Also, while not strictly apart of the alliance the Kid Pirates fought alongside them, against the Beasts Pirates.
After the death of Kozuki Oden, his son, Kozuki Momonosuke, and some of his retainers were sent 20 years to the future, to the current time, and began recruiting allies for their counter attack. After several incidents, Kin'emon befriend the Straw Hat Pirates, who had formed an alliance with the Heart Pirates to take down Kaido. After traveling with the Pirates for some time, Kin'emon learn to appreciate their strength. After the Straw Hat-Heart alliance defeated Caesar Clown and Donquixote Doflamingo, who used their Underworld dealings for Kaido's cause of world domination, the group headed to Zou to reunite with the rest of their parties.
Four Emperors Saga
After the Straw Hat Pirates and their traveling companions reached Zou, it was revealed to them that the minks were allied with the Kozuki Family and that they risked their lives to protect Raizo.
The Straw Hats and Law were taken to see Raizo, and the samurai told the Straw Hats about Oden's death and Kaido's occupation of Wano Country. After being encouraged by Luffy, Momonosuke begged the pirates to help them in the fight against Kaido, which Luffy agreed to, officially forming the Ninja-Pirate-Mink-Samurai Alliance. Law felt somewhat neglected at first as Luffy did not even ask for his opinion on the addition of two new branches into the alliance.
The alliance made plans as to their next course of action: Luffy planned to go to Whole Cake Island with Nami, Chopper, and Brook to rescue Sanji, guided by Pekoms, with Pedro later joining them, while Zoro, Usopp, Robin, Franky, the Heart Pirates, and the samurai would head to Wano Country. Meanwhile, Inuarashi and Nekomamushi planned to search for Marco in order to increase their alliance's strength.
The elephant carrying Zou, Zunesha, came under attack by Jack and his men, but on Momonosuke's command, it wiped out his entire fleet. With everything settled, the alliance split up and began their missions, with Momonosuke and Inuarashi staying on Zou to communicate with Zunesha and defend against any future Beasts Pirates attacks.
Wano Country Arc
Nekomamushi and the Guardians have traveled to an island, and while the Guardians stayed behind, Nekomamushi entered a secret village behind a waterfall, where he met Marco. Marco was shown caring for the villagers as he believed that the village is Whitebeard's keepsake and he wished to protect it. After they talked, Nekomamushi concluded that Marco would not come with him, and Marco asked Nekomamushi to deliver a message to Luffy.
Meanwhile in Wano Country, as instructed by Kin'emon, the Straw Hats (Zoro, Usopp, Robin, and Franky) disguised themselves in order to hide their infiltration from the Shogun, Kurozumi Orochi, guards, and subsequentially the Beasts Pirates. However, Zoro was caught and falsely accused of a series of murders, forcing him to go on the run after attacking the magistrate.
Kin'emon's group worked on gathering allies and after Luffy's group arrived at Wano Country, Kin'emon met up with them at the ruins of Oden Castle and revealed a plan to attack Onigashima, the island where Kaido resided, in two weeks. However, a drunk Kaido arrived to take down Luffy and Law after finding out they had caused trouble on the island. He attacked the ruins of Oden Castle and then fought Luffy, whom he swiftly defeated and had imprisoned.
During Orochi's private prelude party before the Fire Festival, Robin infiltrated the party under the guise of one of the dancing geisha and discovered the shogun's scheduled for the day as well as his company number and weapons. After the chaos at the palace, the Beasts Pirates discovered Kin'emon's secret message and started arresting every person with the mark of the Kozuki Family, a crescent moon, on their ankle. During their search, Hawkins and Drake encountered Nami, Robin, and Shinobu, though they managed to escape with Sanji's help. Meanwhile, several members of the Heart Pirates were captured. When Kin'emon was informed about the leak, he began to worry about his allies and their plan. Meanwhile, Zoro encountered Kozuki Hiyori and swap information with her regarding the members of the Nine Red Scabbards and her brother. Luffy met Hyogoro in the Udon Prisoner Mines and started training his Busoshoku Haki under his tutelage, preparing for his next battle against Kaido.
After learning about the alliance's plan, Shimotsuki Yasuie volunteered to join the fight. When the alliance's plan began falling apart due to Orochi and the Beasts Pirates discovering Kin'emon's secret message, Yasuie sacrificed himself by taking responsibility. After Yasuie's death, the Straw Hats started a fight at the execution area and blew their cover to the authorities. Meanwhile, Law faced against Hawkins in an attempt to free his crew. Desperate to recruit Ashura Doji, Kin'emon framed him for theft, which resulted in Holdem setting fire to the Mt. Atama Thieves' hideout. Ashura was angry when he found out about this, but after seeing Yasu's actions, the two calmly talked their issues out and Ashura agreed to fight alongside them. At the same time, Chopper led a plan to free Luffy from prison by using an amnesiac Charlotte Linlin, which resulting in Luffy taking over the prison and gaining the support of the inmates, including Kawamatsu, a member of the Nine Red Scabbards, and the yakuza bosses loyal to Hyogoro.
After escaping the Flower Capital, Sanji and Shinobu tried to devise a plan to free their captured allies, while the freed Heart Pirates informed Nami about Yasuie's alteration to the alliance's secret message to their allies, before the Straw Hats returned to Kuri to meet up with Kin'emon. With their new allies, the alliance increased their numbers drastically, and after Kawamatsu returned to Ringo and reunited with Hiyori, they acquired a vast amount of weapons for the upcoming battle. Several key members of the alliance gathered in Amigasa Village to begin a strategy meeting.
Two days before the Fire Festival, Kin'emon rallied the alliance teams for the final push before the battle. However, a day later during the night, Orochi sent his men to destroy several bridges across Wano, preventing the major forces from arriving to the meeting port. Desperate, the Scabbards head out on a small boat, preparing to continue the fight by themselves. On the boat, they faced the unavoidable conclusion that there was a spy among them, who is revealed to be Kanjuro. Kin'emon angrily beheaded him, only to learn that it was a copy and the real Kanjuro remained on the coast and that he had captured Momonosuke. As this was happening, the Scabbards' boat was confronted by three Beasts Pirates ships. The Scabbards were saved by the arrival of the Straw Hats, Heart Pirates, and Kid Pirates.
Kyoshiro arrived soon after and he revealed his identity as Denjiro and rejoined the Scabbards. He also revealed that he freed the prisoners in the Flower Capital and the rebels were gathered at Port Habu. Thanks to Kin'emon misinterpreting the new secret message and passing it on to Kanjuro, the spy misinformed his master of the meeting place. Meanwhile, the rest of the allies (sans the Red Scabbards and the pirates) decoded it correctly and met up at the wharf in Hakumai, before departing ahead of Orochi's convoy, leaving the alliance completely undeterred by the enemies sabotage. All the allies then arrived at Port Tokage on a massive fleet. With a total of 5,400 men, the raid on Onigashima finally began. Shocked by their arrival, Kanjuro took Momonosuke and prepared to head to Onigashima to report to Orochi, and faced off against Kawamatsu who tried to free his lord. Kanjuro then conjured a crane with his Devil Fruit ability, and attacked the alliance with a cloud that rained arrows. Momonosuke ordered the alliance to proceed to Onigashima as Kanjuro fled to Onigashima with him. Meanwhile, the Beasts Pirates' ship distanced themselves and attacked the alliance with long range cannons, destroying several of the alliances' ships. The alliance was saved with the sinking of the ship by the hand of the newly arrived Jinbe, who introduced himself as a member of the Straw Hat Pirates. Jinbe then boarded the Sunny, and as the crew prepared to celebrate his return, the Scabbards were joined by Shishilian and Hyogoro as leaders of the alliance's forces to form a plan of attack.
Law then suggested that they would split into four groups: One that would attack Onigashima from the front, two from each of its sides, and one aboard the Polar Tang to submerge and attack Kaido's castle at the back of the island head on. Law stated that the Straw Hats and Kid Pirates would not listen to the plan and strike from the front, making up the first group. Kin'emon and Denjiro volunteered to be leading the groups that would attack from each side, with the rest of the Scabbards on board the submarine. The alliance then noticed that the Straw Hats were already fighting the guards at the port in front of Onigashima, defeating them easily and looting them for the celebration of Jinbe's arrival, but Luffy stopped the party, wanting to celebrate with the entire alliance once Kaido was defeated. The Kid Pirates then sailed past them aiming for Kaido's head, and Luffy ordered Jinbe to catch up to them.
Law's team submerged in the Polar Tang and the rest of the alliance reached the entrance to Onigashima. Usopp knocked out the guards and Kin'emon disguised everyone as members of the Beasts Pirates, allowing them to slip in undetected. With Kin'emon and Denjiro leading their squads, the Straw Hats took out their vehicles, and learned that Luffy and Zoro headed out first chasing the Kid Pirates, making them worry about the two causing problems for the plan. Meanwhile, Luffy came across several members of the Beasts Pirates wasting food, and remembering Tama's starvation, became enraged. Luffy attacked the pirates, and Zoro soon joined him after hearing his reason, making the two's presence known to Apoo, who informed Queen. Queen then offered his men a chance to become one of the Tobiroppo for capturing the intruders. Luffy and Zoro were then attacked by Apoo, who was later attacked by Kid for betraying their alliance.
With the riot growing, Hatcha of the Numbers joined the fight, and Killer informed his allies how to evade Apoo's attacks. Meanwhile, Kin'emon's group reached a brothel and decided to split to corner the Beasts Pirates, and Nami took Carrot and Shinobu to search of Momonosuke. As Kin'emon led half his men towards the back of Onigashima, they were about to be spotted, and Kin'emon ordered them to hide, but Chopper in the Brachio Tank V was not fast enough and was seen by Big Mom. At the same time, Nekomamushi's ship climbed the waterfall and witnessed the Queen Mama Chanter falling after being attacked by Marco.
After Kanjuro deliver Momonosuke to Orochi and Kaido, he informs them about the alliance attack, as Fukurokuju enter the room to inform them about what's currently happening on the Live Stage. Meanwhile, the Submarine team is contacted by Nekomamushi, and Denjiro encounter Sasaki. With Chopper and Usopp luring Big Mom away, Kin'emion's group emarges from the lake and continue their mission, as Nami's group is found by Prometheus who stayed behind. Back at the Live Stage floor, Luffy encounter Ulti and Page One and engage in battle which is quickly interrupted with the arrival of a mask Yamato, who hits Ulti away, and runs off with Luffy, introducing himself as Kaido's son. Elsewhere, Zoro, Kid, and Killer are cornered by several Gifters. Meanwhile, Big Mom has turned around per Prometheus' call to catch Nami, leaving the Brachio Tank free to rejoin Kin'emon.
With Luffy having hard time trusting Yamato, he attacks him, causing the Beasts Pirates to lose track of the two. Meanwhile, disguised members of the alliance including Hyogoro, Robin, and Jinbe, are waiting among the Beasts Pirate, waiting for Kin'emon's signal, and watch as Orochi brings out Momonosuke tied to a cross, and preparing to publicly execute him. At the back of the Island, the Polar Tang surface and Law transport the Scabbards and some of his crew onto the island, where they are met with Nekomamushi, Marco and Izo. At a secluded area, Yamato convince Luffy to explain himself, and remove his mask to reveal that Yamato is in fact a girl, who present herself as a man to became more like her idol; Kozuki Oden.
As the Scabbards head for the entrance to the Skull Dome, they are confronted by Kanjuro and a group consisting of Pirates and Kanjuro's animated drawings. Meanwhile, Yamato continue to tell her story to Luffy, and her inability to leave Wano, as Kaido starts to broadcast to his men about his future plans and their alliance with the Big Mom Pirates, as Big Mom enter the stage after capturing Nami and Carrot and retrieving Zeus. Shocked by Kaido's declaration and him beheading Orochi, Luffy and Yamato fall from the attic and rush to save Momonosuke.
Kaido then offer Orochi's subordinates to join him, which they agree, enraging Hyogoro. During the party, Luffy and Yamato manage to advance with little difficulty, and Luffy removed Yamato's cuffs, which explode and cause a distraction. After the Scabbards defeat Kanjuro's men they enter the castle, and reach Kaido on the main platform, and knock him over it as they all fall to the floor beneath them. As the Beasts Pirates are shocked by the Scabbards' appearance, the rest of the alliance reveal themselves and stand in the way of the Beasts Pirates from interring in the Scabbards' fight. Luffy and Yamato are then confronted by Big Mom and Ulti, allowing Nami and Carrot an opening for escape. Big Mom asks Luffy if he really came to defeat Kaido, and Luffy denies that, momentarily shocking the alliance, before claiming to have come to defeat all of Kaido's allies as well, officially declaring the start of the war. Queen mocks his claims, but soon after learns of the thousands of intruders in Onigasima as the alliance move forward all across the island. Kaido then fly to the roof of the dome with the Scabbards in toe, finding the Mink Tribe waiting for them under the full moon.
Jack then arrive with his men to fight off the minks, as they turn into their Sulong forms. Back inside the dome, Shinobu uses the confusion to get to the platform and tries to free Momonosuke, but is spotted by King and is thrown away. Momonosuke chains then came off and he is suspended in mid air. King tries to go after him but is blocked by Sanji in his Raid Suit, who disable his invisibility and tosses Momonosuke to Shinobu and tells her to ran away before being tossed aside by King. Luffy tells Yamato to go after them and protect them, as Big Mom tries to attack him, learning that Nami has stolen Zeus back. As Big mom turns her attention toward Nami, Franky arrive and run over Big Mom with the Kurosai FR-U IV as Brook bisects Zeus.
With Big Mom knocked over, Luffy gets away and tells Shinobu they can trust Yamato, however as Yamato reveal her pseudonym, Shinobu and Momonosuke are freaked out and flee. Hyogoro tells his allies his plan to fight the Tobiroppo, as Big Mom gets up and Franky prepare to fire a laser at her, however, the arrival of the monsters Numbers, one of whom holding the Brachio Tank, causes the alliance to shift focus. With Franky firing at Jaki instead, causing him to release the tank, Big Mom goes in to attack him from behind, but is stopped by Jinbe tossing her aside and Robin rolling her away. On the platform, Queen notice Luffy and Zoro trying to get to the roof to join the fight against Kaido, and throws them down to the floor below. Despite the massive army against them, Hyogoro smile stating he still believes in their eventual victory, as Franky form General Franky, Sanji gets back up nearly unharmed, and the Straw Hat Pirate reassemble for battle.
On the roof, as the minks end the fight against Jack's group, with Jack the only one left standing and the minks exhausted, Nekomamushi and Inuarashi steps forward to finish off the All-Star. At the Live Stage, the Samurai are fighting the Beasts Pirates, the Oniwabanshu, and the Mimawarigumi, but are having trouble with the two remaining Numbers, so Zoro and Luffy charge in, with Luffy attacking Goki. At the same time, after being uncovered as a traitor, Drake jumps down from the platform to take down Juki and asks Luffy to join their side.
While Several Straw Hats object to Drake's request, Luffy agreed, and in the confusion, Page One and Ulti attack, however before they reach Luffy, Page One is hit with Midori Boshi: Dokuro Bakuhatsu So. Shocked and enraged, Ulti looks for the attacker and sees Nami, whom Usopp dubs to take the blame, causing the two siblings to go after both of them. Meanwhile Sanji and Luffy head towards the castle, but are attacked by Apoo who calls for Hatcha. The Number however, spots General Franky and Franky lures him away. Zoro clashes with Drake, mistrusting him, however the two soon join forces to take down Apoo, however before they reach him, Queen uses his gatling gun from the platform to indiscriminately fire at the people below. Back on the roof, Jack falls defeated by the minks, and the battle between Kaido and the Scabbards begin. Despite the Scabbards relentlessly sends a flurry of strike that manage to hurt Kaido and drew blood, they are unable to cause a serious injury.
At the Live Stage, the bullets Queen fired are revealed to be infecting the targets with Ice Oni, another plague by the All-Star design, that spread throughout the area to allies and foes alike. Meanwhile, Luffy and Sanji had entered the castle and are fighting their way up as they are joined by Jinbe. Elsewhere, Yamato saves Shinobu and Momonosuke from Sasaki's men. On the roof, Kaido rises from the Scabbards latest attack and strikes back, severing Kikunojo's arm with an air cutting roar. Kin'emon cauterized the wound as Kaido turned back into his human form, before the battle resumed. Inside the dome, Chopper tries to figure out a way to cure everyone, as Queen informs those present that the virus would kill them in one hour from infection, and gave Apoo a vial containing the antibodies, declaring a game to see if they can capture him before they die from the virus effects, while threatening to kill Apoo if he "loses". Meanwhile, Yamato fights Sasaki's men while protecting an injured Shinobu, introducing herself to Momonosuke.
Outside, while Marco confronts Big Mom and Perospero, Carrot and Wanda appear, saving him from Perospero's arrow, and preparing to face the Candyman in order to avenge Pedro. At the Live Stage, the chase after Apoo continue, as Chopper tries to understand the way the Ice Oni works. Elsewhere, Ulti and Page One have caught up and severely beaten Usopp and Nami, with Ulti forcing the latter to admit Luffy's dream to be unachievable. True to her heart, Nami reaffirms her beliefs in Luffy, and as Ulti prepare to kill her, Tama and Komachiyo show up to save the Straw Hats. Tama then flees with Nami and Usopp upon Komachiyo, while having Hihimaru stall the two dinosaur Zoans. Meanwhile, Sasaki's men are unable to pass Yamato, so the Tobiroppo himself prepare to fight, however the arrival of Franky and Hatcha create an opening for Yamato to escape. With Shinobu and Momonosuke in tow, Yamato asked Franky to hold off Sasaki as she take down Hatcha with a single blow. At the same time, Law finds a Poneglyph at the castle basement, and Kid gather weapons from across the castle as he and Killer head out to fight Kaido.
Zoro followed Big Mom's trail as she suddenly appears and flew directly to Kaido, where he noticed Kikunojo's arm fall from the roof, enraging him to the point where he defeated Apoo with a single strike. The swordsman retrieved the vial of antibodies, which he entrusted to Chopper, who informed his surrounding how to counter the plague while also promising he would make more of the antibodies for allies and foes alike, per his doctor oath. Marco then appeared, offering to help Zoro reach the roof. Elsewhere, Sanji fell for Black Maria's trap and is captured, while Luffy and Jinbe headed for the fourth floor, with the alliance members creating an alternate route to circumvent the blockades around the stairs. However the island starts to rumble, as Kaido, having defeated Izo and the Red Scabbards, used his power to lift the entire land mass from the ocean, making it float towards the Flower Capital.
At the Live Stage, Marco uses his flames to reset the timer for the Ice Oni death count, as Chopper is assisted by Miyagi and Tristan in making more antibodies. The yakuza and Drake volunteered to guard Chopper while Zoro headed for the roof with Marco. Inside the castle, Jinbe and Luffy continue to fight their way up, though upon encountering Who's-Who and his subordinates, Jinbe offered to stay behind in order to allow Luffy to proceed. Meanwhile, Momonosuke's group hide at a secluded storage room.
While the Beasts Pirates attempt to stop Marco, he still took flight with Zoro, causing King and Queen to personally attempt to stop him in their full beast forms, though Marco instead restrained them, as he threw Zoro to the roof. As Luffy reached the top floor, he finds that the Mink Tribe, who had retreated after defeating Kaido's back up, had cleared the route to the top of the dome, which Luffy gratefully takes. Atop the Skull Dome, he finds that Zoro, Law, Kid and Killer were already there staring down Kaido and Big Mom. When he noticed the defeated samurai, he walked up to them, where Kin'emon tearfully passed on the torch to him. When Kaido moved in to attack the Straw Hat captain, Luffy had Law use his ability to move the fallen samurais to the lower floors. Luffy then evaded the Strongest Creature's attack, before starting their battle with a hit strong enough to hurt Kaido. 
- Luffy was the one who came up with the alliance's name, causing Usopp to state it was too long and Nami to question if the "Ninja" part was needed as the ninja, Raizo, was affiliated with the samurai. However, the consensus was that it was needed, mainly due to Luffy's enthusiasm for ninjas.
- In Chapter 973, a waning crescent moon was shown, implying that Oden's death, and subsequently the Fire Festival, occurred at the end of the month. This matches Hawkins' prediction in Chapter 913 regarding Luffy's future.
- In Chapter 987, however, a full moon is shown during the event.
