Sasaki[5] is one of the Tobiroppo, the strongest six Shinuchi of the Beasts Pirates,[6] and leads the crew's Armored Division.[7] Before joining the Beasts Pirates, he captained his own crew.[3]

Due to his actions and role, he is a supporting antagonist in the Wano Country Arc.


Sasaki's color scheme in the manga.

Sasaki is a very tall man at just shy of 3.2 meters,[4] with a portly build and light skin. He possesses sharp and slanted, blue eyes underlined by notable creases, a mildly hooked nose, and a fang-filled mouth with notably oversized bottom canines (jutting out even with his mouth closed), as well as a flat chin. His shaggy hair is colored yellowish-green and reaches down to his middle back, with a golden hoop earring visible on both his ears. A black tattoo is located around his shoulder areas, including the upper arms, chest, and back, with many curved, vane-like shapes bringing on a resemblance to wings.[6][8][9]

As for clothes, Sasaki's seem a distinct blend of traditional Japanese and a soldier's or dictator's attire. On his head is a military-style cap with a black, low-set visor. Its white crown is extra-wide and puffy, dented breadthwise with the front raised, and split by a lengthwise seam. Above the black bottom edge (spaced from it) runs a black band lined with a row of gold studs, holding in the front a golden badge depicting a double-cross shape (eight-armed, the diagonals less prominent, with a small middle stud). Set below, front and center, is a pair of slender, golden horns that curve upward, lending Sasaki (together with his fangs) a rather demonic look. Otherwise, the man wears a cloak akin to a seaman's, slung on his shoulders with the sleeves hanging back, that has a folded standup collar bearing on each side a simpler version of the hat's badge. The coat has a solid-white coloration over its upper half, which ends around waist level with a downward-facing flame motif, contrasting against the orange-colored rest of the coat. Below, Sasaki's torso is bare, partly showing off the aforesaid tattoo. For lower wear, Sasaki dons a hakama-like article resembling the bottom half of a double-breasted trench coat, which is flame-patterned the same as the cloak (though with the upper half beige-colored instead of white), closed by eight buttons, and held up by a plain dark, buckled belt. Finally, Sasaki sports a pair of brown gloves and double-toothed geta sandals.[6][8][9]


Outside of battle, Sasaki is shown to be a relatively calm, easygoing man, yet is also prone to derision, not above scoffing at even those of equal rank.[6] Still, he acts cordial toward those he considers friends, such as formerly "Kyoshiro", but will not tolerate any breach of fidelity; if betrayed, he will aim to ensure the traitor pays a steep price.[9][10]

Rather ambitious, Sasaki seeks to become one of the Beasts Pirates' All-Stars by claiming a spot from the current ones, causing him to disregard their senior authority. This resolve, according to King, arises from Sasaki's past as captain of his own crew, and bears out on his part a high degree of confidence in his own strength, enough for him to look forward to gaining chance to directly challenge an All-Star.[8] In combat, Sasaki is similarly self-assured, especially due to his ability to become a dinosaur, believing dinosaurs to be the strongest animals that ever existed.[11]

It is implied by Kyoshiro that Sasaki is fond of partying, since the former thought that Sasaki's presence outside the Golden Kagura was uncharacteristic of him, and he conducted his search for Yamato with a sake bottle in hand, apparently fond of drinking.[9] However, Sasaki sees himself as above drinking with rank and file, expressing his wish to drink with none other than Kaido.[8]



Like the other Tobiroppo, Sasaki seems to heavily respect Kaido. When Ulti insulted their boss in his absence, Sasaki nonetheless grew shocked.[6] He also seems to be on casual enough terms with Kaido to express his wish to drink with him during the Golden Kagura, stating to have no interest in fraternizing with mere underlings.[8]

On the other hand, Sasaki (like Who's-Who) looks at the current All-Stars foremostly as obstacles in his pursuit to take one of their spots, thus acting insubordinate toward them and ignoring any summons order without Kaido's name attached to it.[8] Further, while friendly enough with his fellow Tobiroppo to sit and banter with them, Sasaki views them as competition, given that some of them too aspire to climb up a rank. He mockingly discouraged X Drake and Page One from pursuing such advancement, effectively calling the latter dead weight.[6]

Sasaki holds his Armored Division in high regard, noting how he could not afford to lose them.[12] When going out to battle with his men, he has a large rhinoceros SMILE user carry him on a throne.[7]



Sasaki saw a friend in Denjiro during the latter's time posing as Kyoshiro, though with Denjiro's backstabbing him during the latest Fire Festival, Sasaki swore he would avenge himself on the samurai.[9][10]


Sasaki does not seem to think too highly of Yamato despite them being Kaido's child, calling Yamato a brat behind their back.[5] However, he still addresses Yamato as "Young Master" (ぼっちゃん Botchan?), though he seemed not too upset by Yamato's apparent betrayal of the Beasts Pirates and had no qualms about personally fighting Yamato, even deeming their suggestion that they could take him on while simultaneously protecting Shinobu and Momonosuke as an insult.[13][14][15]

Abilities and Powers

As one of the Tobiroppo, Sasaki holds great authority in the Beasts Pirates, only Kaido himself and the All-Stars ranked above him;[6] in particular, Sasaki leads the crew's Armored Division.[7] Further, as an ex-pirate captain, Sasaki used to have full command over his own crew at some point.[3]

Combat-wise, Sasaki can be assumed to be formidable as one of the strongest six Shinuchi, potentially worth challenging the All-Stars for their post (something Sasaki seems confident in his ability to do).[8]

Devil Fruit

Sasaki transformed into a triceratops.

Sasaki ate the Ryu Ryu no Mi, Model: Triceratops, an Ancient Zoan-type Devil Fruit that allows him to transform into a full triceratops and a human-triceratops hybrid at will.[11]

As an Ancient Zoan, this power grants Sasaki an immense increase in physical strength, allowing him to charge into opponents with great force, enough to knock back a powerful, 13m-tall robot. Furthermore, with his thick, hard triceratops skin, Sasaki enjoys a notable increase in durability, enough to be unfazed by heavy, explosive artillery fire.[11][16]

As a triceratops, Sasaki bears three long, pointy horns on his head. His primary method of combat is to charge at his opponents head-first and pierce them with his horns.[17]


Sasaki carries on his left hip a katana-style, albeit very broad-bladed, sword with light, greenish-gray tsuka-ito forming rhombus gaps on the hilt (being gold-colored below) and an orange pair of tufted cords tied to it, a gold kashira, a rectangular tsuba that is also gold, and a saya colored the same as the tsuka-ito.[9] The sword's blade is distinct: segmented vertically at an angle, each section has its own temper line resembling a gunome style.[12] Sasaki's skill in wielding the sword remains to be seen.



Sasaki captained his own pirate crew before he joined the Beasts Pirates. After joining them, he developed the goal of becoming one of the All-Stars by replacing a current one.[3]

Wano Country Arc

The Tobiroppo, including Sasaki, arrived on Onigashima following the beginning of the latest Fire Festival.[1] Kaido had supposedly summoned them to his castle, and while waiting they started chatting about who of them would become the next All-Star if Queen died. As X Drake denied any interest in promotion, Sasaki welcomed his noncompetitive attitude, drawing Ulti's ire by suggesting Page One do the same. Sasaki then intimated what he thought Kaido's reason was for calling them, and consequently grew shocked with the other four when Ulti insulted their Governor-General.[6] Kaido thereafter greeted the six in his castle, and they learned how King was the one who had summoned them, the latter mentioning to Sasaki and Who's-Who their goal of becoming All-Stars and telling them to know their place. Kaido then gave the Tobiroppo the mission of finding his "son" Yamato, stating he would let them battle one of the All-Stars for their post if they succeeded.[8]

Sasaki chained up by Denjiro.

Later on, letting his men search for Yamato near the gate located on the southwest of the island, Sasaki ran into Denjiro, whom he still thought to be his ally "Kyoshiro". Thus, with Sasaki's guard down, Denjiro managed to have him chained up, with Sasaki bewildered at the apparent betrayal.[9] Once the Ninja-Pirate-Mink-Samurai Alliance's raid on Onigashima was fully raging, a massive attack from Big Mom reached Sasaki all the way from the Skull Dome and knocked over the sacred tree he was tied to, freeing him from his chains. Afterwards, he was found by his lackeys and, while being informed of the situation, swore revenge on Denjiro, whom he had considered his friend. He later received a call from King informing the Tobiroppo that the challenge for the right to fight an All-Star was cancelled, and that they were to stop the enemy alliance from getting to the Skull Dome's roof where Kaido was fighting the Nine Red Scabbards.[18]

Sasaki and his subordinates confront Yamato.

Thereafter, King ordered the Tobiroppo to bring him the head of Kozuki Oden's son, Momonosuke, in order to break the enemy samurais' will to fight. Sasaki encountered the boy and Shinobu while they were fleeing the castle, in the Right-Brain Tower. He had his men, the Armored Division, fire bazooka and arrow shots at them, telling the kunoichi not to interfere. Just as Shinobu was about to be finished off by a Gifter, Yamato came in to block the attack, prompting Sasaki to question Yamato's motives.[19] Reiterating how killing Momonosuke would see their mission completed, Sasaki looked on in surprise and consequent annoyance as Yamato used their body to shield Momonosuke and Shinobu from more explosive rounds, and then knocked out another Gifter.[20]

As Yamato continued engaging his division, Sasaki commented on Yamato's declaration that they would not leave Shinobu behind, taking it as insult due to the implication that they could defeat him while protecting dead weight. As Sasaki began drawing his sword, Franky within the General Franky appeared being chased by the Number Hatcha, with the giant then blowing a hole into the floor trying to hit said robot. When Yamato took the chance to escape with Shinobu and Momonosuke through the hole into the lower floor (but not before knocking out Hatcha as they did so), Sasaki irately commanded his men to follow them.[21] When Franky then overwhelmed his men with his General Launcher from inside his robot, Sasaki told them to move aside before activating his triceratops transformation and charging into the robot, knocking him back a fair distance.[11]

Sasaki pierced by Franky's Franken sword.

Soon after, Sasaki and Franky were locked in fierce combat.[22] As Franky shot at Sasaki with his General Left, the latter (still in his full Beast Form) remained unfazed as he again charged into the General Franky. Franky managed to stop the charge by having his robot grab hold of Sasaki's nasal horn, then shoulder-threw the dinosaur into the wall behind them, though Sasaki quickly regained his balance. As he prepared yet another charge at Franky, Sasaki had his Armored Division restrain the General Franky. However, as Sasaki began rushing toward them, he was surprised by the suddenly-appearing Nami and Usopp, who had managed to brainwash numerous Gifters into becoming their allies thanks to Tama's dangos. Said Gifters helped Franky narrowly avoid Sasaki's charge, with the also-arriving Ulti and Page One clarifying the Gifters' betrayal. Usopp then fed dangos to Sasaki's subordinates, making them betray Sasaki. While the latter was distracted, Franky took the chance to surprise-attack him with his "Franken" sword, slashing Sasaki in his belly using Shori no V-Flash.[23]

As Sasaki continued clashing with Franky, the two combatants heard Sanji's cry for help broadcasted throughout Onigashima, with Sasaki laughing at Sanji's predicament.[24]

Anime and Manga Differences

In the anime amid Kawamatsu's flashback showing his past with Onimaru (well before the Tobiroppo's introduction on Onigashima), Sasaki is seen in a brief shot alongside Kaido, the All-Stars, and Who's-Who, in Kawamatsu's imagination; despite this taking place 13 years before the present day, Sasaki (like the others) is depicted looking the same as his present-day self.[2]


  • Sasaki is likely named after the card game "44A", also known as Sasaki (ササキ?), which is a popular card game in North Korea, following the card game-themed names of the Shinuchi.
  • Sasaki's favorite food is asparagus,[4] hinting at his ability to transform into a herbivorous dinosaur.
  • Sasaki has been seen holding a sake bottle labelled with 鬼守 ("Demon Protecting").[9] This could be a reference to the well-known Japanese Onikoroshi (鬼ころし? "Demon Killer") brand of sake, with the meaning reversed to evoke Sasaki's allegiance to his Onigashima-based crew.
