Duke Inuarashi is a canine mink and one of the two rulers of the Mokomo Dukedom, dubbed the "Ruler of Day" as he rules over the Mokomo Dukedom from 6:00 AM to 6:00 PM. He and Nekomamushi serve as retainers for the Kozuki Family of Wano Country, as members of the Nine Red Scabbards. Alongside Nekomamushi, he was once a member of the Whitebeard Pirates and Roger Pirates, serving under Kozuki Oden. Pedro has claimed he and Nekomamushi must not be allowed to die because "the world is waiting for them". Inuarashi is an incredibly large and grizzled canine mink. He wears a small pair of blue sunglasses and has shoulder-length black ears, a white beard, and a large and bushy tail. During the battle against Jack, he wore a dark-colored striped suit with a frilled collar, a belt, a light-colored cape, and a helmet. After waking from his coma, he wore a king-like robe, and his head and torso were covered in bandages. Like all the retainers of the Kozuki Family, Inuarashi bears the family crest somewhere on his body. While being tortured by Jack, Inuarashi lost his left leg. Inuarashi is a kind, noble, and humble mink who is deeply loved and respected by his people due to his great benevolence. He was eager to meet the Straw Hat Pirates after they saved the Mink Tribe, indicating a grateful personality, and he downplayed his strength when he was complimented by Luffy.
Inuarashi has a very refined and sophisticated personality as he is very polite and soft-spoken in speech. He refers to himself with "watashi" and always speaks to people including enemies in a very courteous manner. Due to his gentleman sophistication, Inuarashi strongly dislike barbarism, as he was greatly shocked by Jack's completely unreasonable and violent nature. He also hold strong contempt for Nekomamushi, who he insultingly called a Monster Cat due to the latter's aggressive and wild personality. Despite being the strongest warrior on Zou, Inuarashi prefers diplomacy over aggression when dealing with hostile parties. He cares immensely for his people and their rich cultural history, to the extent that he was willing to lay down his sword to reason with Jack and the Beasts Pirates and would have allowed them to search for Raizo if they ceased their attack. During the brutal interrogation by the Beast Pirates for Raizo's whereabouts, Inuarashi pleaded with Jack and his men to spare his citizens from their brutality despite being subjected to horrendous torture himself. However, he is also firmly loyal and possesses an incredibly strong will, having absolutely refused to reveal Raizo's presence on Zou despite the brutal torture at the hands of Jack even when he lost his leg, and was fully willing to risk the kingdom's destruction in order to protect his friend. As one of the two rulers of the Mokomo Dukedom, Inuarashi holds a large amount of influence over the Mink Tribe. Inuarashi has full authority over the entirety of the Inuarashi Musketeer Squad, to the point of having control of the combat force delegated to Shishilian and the other two members of the three Musketeers, who take their orders directly from him. According to Wanda, he is the country's strongest warrior and fought evenly against Jack, the right hand man of the Yonko Kaido with a Beli1,000,000,000 bounty, before the latter poisoned him with Caesar Clown's Koro gas.
Alongside Nekomamushi, Inuarashi is one of the two strongest minks of the Mokomo Dukedom. He possesses immense physical strength, durability, and endurance, having stopped Jack's enormous trunk, which had destroyed several buildings in a single swing moments before, with one hand while only becoming slightly winded from doing so. Like all minks, he can use Electro. In the anime, Inuarashi applies immense force in his swordsmanship, allowing him to defend himself multiple times from Jack's assault in his giant mammoth form with only his rapier. Inuarashi is also extremely agile despite his large physique. In the anime, he could attack Jack at extremely high speed and swiftly evade and counter his assaults. He can even run on walls as shown when he sprinted on the surrounding buildings of Kurau City to gain an advantage in speed. Inuarashi is also proficient in kicks as he could kick with great force to topple Jack, a massive man, from behind and send him crashing into a building, demolishing it in the process. It is unknown how much the loss of his leg affects his overall combat abilities, but he managed to clash evenly with a one-armed Nekomamushi. The force of their clash is sufficient enough to create a powerful shockwave that blow the surrounding minks away. Inuarashi could also clash with Shutenmaru equally in swordplay. As the leader of the Musketeers squad, Inuarashi has an extremely high level of skill in swordsmanship. He could easily hold his own against Jack in his Ancient Zoan form and could perform strong defensive blocks to defend against Jack's attacks with his sword. In the anime, he was shown combining Electro with his sword skills to use electricity enhanced slashes for powerful offense. Inuarashi's swordsmanship is enough to clash with Nekomamushi's spearmanship. Inuarashi wields a rapier, which he can channel Electro through. While dueling Ashura Doji, he wielded a katana.Inuarashi possesses the ability to use Busoshoku and Kenbunshoku Haki. In the distant past, Inuarashi and Nekomamushi were friends. When they were children, they were told of the pact the Mink Tribe made with the Kozuki Family. Curious, they left Zou and journeyed to Wano Country, but got shipwrecked. They were discovered at Kuri Beach by Kawamatsu. Afterwards, the three were caught and persecuted by some humans until Kozuki Oden came and rescued them. They then followed Oden back to Kuri and became his retainers When they were running low on funds, the retainers attempted to steal money from Shimotsuki Yasuie, but they were caught. 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. Following Yasuie's advice, they educated themselves and trained to become dignified warriors. 30 years ago, they visited the Flower Capital with Oden.
