Ashura Doji is a retainer of the Kozuki Family as one of the Nine Red Scabbards once led by Kozuki Oden. After Oden's death he returned to being a criminal under the name Shutenmaru, assuming leadership of the Mt. Atama Thieves. He initially severed his ties with the Kozuki Family in the present but rejoined after witnessing Yasuie's death. Ashura Doji is a very large man with light pink puffy hair that is gathered into a topknot. He wears an open kimono with flowers on it that leaves his chest exposed. He has floral tattoos on his arms and upper chest. Ashura was once a dangerous outlaw who was extremely violent in the past. He claimed that he hated people with wealthy status. After being defeated by Kozuki Oden who chose to spare his life and offered him a chance to live a peaceful life by rebuilding Kuri, Ashura became one of his most loyal followers out of immense gratitude. He and the other Nine Red Scabbards attempted to steal money from Shimotsuki Yasuie in order to support Oden. Ashura is even willing to study hard to improve himself on Oden's behalf.
Ashura is an extremely loyal person as he still refers to Oden as "Oden-sama" even after his death. His loyalty is also seen when he patiently tried to assemble an army of samurai to support the Kozuki Family. He is also very brave and almost fearless. When he encountered Jack in Okobore Town who is the ruler of Kuri and one of the Beasts Pirates All-Stars, the former was not afraid to attack the latter immediately and even did not fear Jack's reputation. However, he is also cautious of Kaido's strength, but he will fight Kaido if he needed to. He was also a very caring person. When the samurai he had gathered tried to attack Kaido at Onigashima, he cried and tried to stop them, but his words were in vain because they did not listen. After losing these comrades, Ashura finally lost hope and returned to being a criminal under the alias Shutenmaru and formed a group of thieves because he was disillusioned and nihilistic towards the country. After returning to being a criminal, he became an aggressive and prideful person. He had stolen both from Wano's Shogun, Kurozumi Orochi, and from the poorest citizens for the exact same self-sufficiency motives. He also did not care what would happen to this country due to the lack of strong and noble people like Oden. As such, Ashura was disgusted with Luffy's heroism to feed the citizens of Okobore Town. He also refused to rejoin the Kozuki Family after they returned for their campaign to overthrow Kaido and Orochi. Despite his callous and nihilism towards the citizens of Wano, Ashura still has some compassion as he secretly felt sympathy towards the citizens of Ebisu Town who had lost the ability to express sadness and anger from eating the SMILEs that Orochi manipulated them into eating. He was also distraught when Yasuie was executed, showing that he still cared greatly for those that were his comrades. After deciding to rejoin the Nine Red Scabbards, Ashura became friendly with his comrades again. Ashura is one of a few samurai known to still use the Sunacchi, which was once part of the old dialect of Kuri in Wano Country. Ashura and his men use it frequently amongst themselves and in battle. Ashura seems to enjoy drinking alcohol. In the past, he also drank blood from a decapitated snake. As leader of the Mt. Atama Thieves in the present, Ashura has complete authority over the group. Proving their combined skills at thievery, Ashura and his followers successfully raided Orochi's personal farm whilst not able to be stopped by anyone serving the shogun (be it samurai or the Beasts Pirates). Furthermore, he proved his ability to be able to have hidden from them all along. 25 years ago, while Oden was away with the Whitebeard Pirates, Ashura assumed control of the Yakuza in Kuri as the new Yakuza boss. It was said that under his control, Ashura was able to keep both the yakuza and bandits in the region from going out of control in Oden's absence.
Combat-wise, Ashura Doji is extremely powerful, as he was once feared as the "Strongest Monster of Kuri" the most dangerous villain frequenting said Wano province in its era of chaos—until he was defeated by Oden four decades ago (the latter taking a whole night to take down both Ashura and his then-cohorts). Even more, in the last 20 years, Ashura claims to have become stronger. Indeed, Kin'emon hails Ashura as one of the strongest of the Scabbards (alongside Kawamatsu and Denjiro) and worth the strength of 100 men. Kaido himself, an Emperor, sought to recruit him and Holdem, a Beasts Pirates headliner, surmised that Monkey D. Luffy may be Ashura's subordinate going by his power. Perhaps most impressively yet, Ashura was able to fight evenly against Jack, one of Kaido's three strongest men worth a Beli.png1,000,000,000 bounty, even dealing him a serious wound, and additionally matched up to Inuarashi, one of the two strongest warriors of the Mink Tribe, in a sparring match. Though strong as he may be, Ashura is well aware that he has no chance against Kaido by himself, preferring to retreat when faced with him a second time. Being hailed as the strongest outlaw of Kuri during his youth, Ashura can apply tremendous physical strength to his swordsmanship, able to clash with Jack, one of the three Disasters of the Beast Pirates, and even gave the latter a massive wound across his chest. Alongside his fellow Scabbards, Ashura managed to push Kaido off his feet when ambushing him. Despite his large build, Ashura is extremely fast, being capable of charging towards Jack in an instant. Ashura also possesses a great amount of endurance, as he was seemingly unaffected when Jack cut him on the shoulder. Ashura is an extremely skilled and powerful swordsman. With one slash, he was able to give Jack a large cut across his chest and break one of his shotel blades. He then proceeded to fight evenly with Kaido's right-hand man in what spectators considered to be a high-level duel. He is capable of emulating Oden's signature Oden Nitoryu style, allowing him to wield two swords at the same time and perform one of his techniques.
