Ashura Doji is a retainer of the Kozuki Family and is one of the Nine Red Scabbards. After Oden's death, he returned to being a criminal under the name Shutenmaru and became the leader of the Mt. Atama Thieves. He initially severed his ties with the Kozuki Family, but rejoined after witnessing Yasuie's death.
Ashura Doji is a very large man with light 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 criminal in the past. After being defeated by Kozuki Oden, he became his follower. It seems that he values strength. At some point, he and the other Nine Red Scabbards attempted to steal money from Shimotsuki Yasuie in order to support Oden.
Ashura is an extremely loyal person as he still refers 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 have 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 seems to enjoy drinking alcohol.
Kozuki Family and Nine Red Scabbards
In the past in lawless Region of Kuri before the Kozuki Family's dethronement, Ashura Doji was confronted by Kozuki Oden, the son of Shogun Kozuki Sukiyaki. He was later defeated by Oden and became his follower. He and the other retainers attempted to steal money from daimyo Shimotsuki Yasuie to support Oden. Even after his death, Ashura still refers to him as "Oden-sama", showing an undying respect and loyalty to the daimyo of Kuri. Ashura and the other retainers seems to have get along well, except Kikunojo. However, after Oden's death and Wano Country was taken over by Kaido and the new Shogun Orochi, Ashura tried to support the Kozuki Family by gathering allies and waiting for the missing Nine Red Scabbards and Momonosuke to return, even though it ended up in vain because all of his allies had died at the hands of Kaido. This led him to severe his ties with the Kozuki Family.
Later, after the missing Nine Red Scabbards returned, their relationship became strained. Ashura became angered and frustrated at Kin'emon and the others for having vanished for so long. Ashura said that he only respects and is loyal to someone named Oden, not to his family. In truth, he was angered because some of his comrades died in vain ten years ago. His feeling of resentment for the family was so much that he even refers Momonosuke, who is Oden's son without any honorifics, and resulting Kikunojo expressing his disappointment. The closest to any camaraderie Ashura expressed was that he spared them from his banditry. However, Kin'emon made it clear that he would make Ashura their ally and had no qualms framing him for theft. This only made Ashura angrier after he found out about it, but he was still lenient enough to listen to Kin'emon's apology and pleas. Ashura then showed Kin'emon and Inuarashi the graves of fallen comrades and explained what happened to their allies after they had lost the patience in waiting for their return. Ashura finally rejoined his team again and invited his bandit group to take part in the fight against Kaido and the Beasts Pirates.
Ten years ago, Ashura tried gathering forces to support the Kozuki Family in the fight against Kaido. However, after his comrades threw their lives away, Ashura lost hope and seemingly gave up. Kaido recognizes his strength and wanted him to join his crew, but Ashura had no intention of joining and pledging loyalty to the Beasts Pirates. However, he is well aware of Kaido's strength and would try to avoid him as possible.
Despite his intimidation of Kaido, he is not afraid to pick fights with the Yonko's subordinates. When Ashura encountered Jack in Okobore Town, the former did not hesitate to attack the latter and did not even fear his reputation.
With Ashura rejoining the Scabbards, he intends to help defeat Kaido.
Kaido seems to be unaware of Ashura's connection with the Kozuki Family as he only knew him as a thief called Shutenmaru.
Mt. Atama Thieves
All the members of the Mt. Atama Thieves are extremely loyal and supportive of Shutenmaru, aiding him in stealing and robbing. When Shutenmaru decided to join the Kozuki Family's revolution, all his underlings happily agreed to join him.
Abilities and Powers
As the leader of the Mt. Atama Thieves, he has complete authority over his men. According to Kin'emon, during his time as one of the Nine Red Scabbards, he was one of the most powerful members alongside Kawamatsu and Denjiro.
Proving his skills at thievery, Ashura and his followers successfully raided Orochi's personal farm whilst not being 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.
In combat terms, Ashura Doji is extremely powerful, as he was once feared as the most dangerous out of all villains that frequented Kuri in its era of chaos until he was defeated by Oden. In the present, Ashura claims that he has gotten stronger in the last 20 years. Even Kaido, one of the Yonko, sought to recruit him, and Kin'emon hails him as being worth the strength of 100 men. Holdem, a Beasts Pirates headliner, surmised that Monkey D. Luffy may be Ashura's subordinate going by his power. Most impressively yet, Ashura was able to fight on par with Jack, Kaido's right hand worth a 1,000,000,000 bounty, even dealing him a serious wound, and additionally matched up to Inuarashi, one of the two strongest members of the Mink Tribe. Though as strong he may be, Ashura is well aware that he cannot defeat Kaido, preferring to retreat when faced with him a second time.
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. Despite his large build, Ashura is extremely fast, being capable of charging towards Jack in an instant. He also possesses a great amount of endurance, as he was seemingly unaffected when Jack cut him on the shoulder.
Ashura Doji is a master swordsman and one of the most powerful samurai in Wano. 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.
Over 20 years ago, Ashura Doji was the most dangerous criminal in the lawless region of Kuri. However, he was confronted by Kozuki Oden and defeated, causing him to become a follower of Oden and aiding him in his efforts to bring peace to Kuri.
Sometime after the Nine Red Scabbards were assembled, Daimyo Yasuie caught them stealing money from him. Instead of punishing them, Yasuie allowed them to take the money and encouraged them to use it to become better people for the sake of Oden and Wano.
Ten years after Oden was executed by Kaido and the new shogun Kurozumi Orochi, Ashura had many friends who became too eager to fight Kaido and Orochi and did not fully believe Toki's prophecy about the return of the missing Red Scabbards. Thus, they impatiently went straight to Onigashima to fight Kaido. Ashura tried to stop them from throwing their lives away, but these words were in vain, and his comrades ultimately perished at the hands of Kaido.
Distraught at his comrades' pointless demise, Ashura eventually lost hope, went back to being a criminal, and adopted the alias Shutenmaru. He also formed the Mt. Atama Thieves. At some point, he encountered Kaido, in which Kaido wanted him to be part of his crew. Ashura also managed to acquire the blueprints of Kaido's fortress.
Wano Country Arc
Ashura and his thieves came to Okobore Town, where they stole the fresh food that Luffy had given to the residents there. He was confronted by an old woman who believed that the samurai would return to protect them, and in response, Ashura prepared to attack her. However, before he could, he was confronted by Jack of the Beasts Pirates. Jack asked about the Straw Hat Pirates and mentioned that Ashura had only been left alive because Kaido wanted him as his subordinate. He reiterated that he would never join them and then attacked Jack with a massive cut, causing the two to begin fighting. Jack managed to wound Ashura, but he was unwavering. However, their duel was interrupted when Kaido came flying in to tell Jack to bring the Straw Hats to him.
Ashura and his gang then began retreating to the forest. Kaido spotted him and asked him to become his subordinate. Ashura prepared for a fight, but Hawkins drew Kaido's attention to Oden Castle. The thief was then angry at Kaido for destroying the castle ruins, and after Luffy attacked Kaido, Ashura told his men to retreat to the mountain before watching Luffy's futile attempt to defeat Kaido. After Kaido defeated Luffy, Ashura saw the unconscious Luffy knocking out some of the Yonko's subordinates with Haoshoku Haki and realized he had the same power as Oden. He then departed from Okobore Town.
At Mt. Atama, Ashura clashed with Inuarashi, but the fight was interrupted by Kin'emon. Ashura stated that while he admired Oden, he never swore loyalty to the whole entire family. However, Kin'emon ignored this claim and emphasized that he was determined to make Ashura their ally once again.
Sometime later, Mt. Atama was set on fire by one of Holdem's subordinates. Enraged, Ashura decided to go to Bakura Town to retaliate. He and his gang later entered Bakura Town and witnessed Yasuie's execution on the broadcast. After the execution, he was the only one of the Nine Red Scabbards to hold his tears after Yasuie’s death, and thereafter asked Kin'emon and Inuarashi if they knew about the SMILE fruits.
Outside Bakura Town, Ashura learned that Kin'emon framed him for theft. He got angry and knocked Kin'emon to the ground. Kin'emon and Inuarashi apologized and once again asked Ashura to join them. Ashura then told Kin'emon and Inuarashi to follow him, wanting to show them something. When they arrived, Ashura showed them the graves of their dead comrades and explained what had happened to their allies ten years ago. He recounted how they had all lost patience and had tried to fight Kaido, but were all killed in battle. Ashura then determined that it was time for him to rejoin his comrades to avenge those who had fallen and to also overthrow Kaido and Orochi to restore the position of the Kozuki Family. Inuarashi and him then rejoiced and bragged to Kin'emon about how they had twenty years more fighting experience than him now. Upon being called a duo of geezers by Kin'emon, the three began arguing, much to the worry of Ashura's henchmen.
Ashura later took Kin'emon and Inuarashi to an abandoned port and showed them ships that could carry their troops to Onigashima. Ashura then gave Kin'emon the blueprints of Kaido's residence. While Kin'emon was speaking to Raizo via Smart Tanishi, Ashura was surprised to hear the number of allies Raizo's group gained at Udon.
- Like O-Tama, he speaks in a dialect that is unique to a specific region of Japan. This area is known as Kagoshima, one of the prefectures created during the Meiji Era as the country transitioned from the isolationism enforced by the Shogunate.
- The names Shutenmaru and Ashura Doji are likely a reference to Shuten-dōji, a mythical oni leader from Japanese legends.
- The middle kanji of his alias, "天" (ten?), is the Japanese kanji for "Heaven". This same kanji is seen on the sake bottle he carries.
