Hashibira Inosuke

Inosuke was raised by boars - all his life before the Final Selection, he lived in the forest on the mountain, until one day he decided to go on a journey to become stronger. He always believed that he never had parents, but later he finds out that he was born into a dysfunctional family, whose father often drank and beat his wife, so she, taking the newborn Inosuke, ran away from the family to the temple of the Cult of Eternal Paradise, founded by the demon Douma. He took them to live in his temple. It is worth mentioning that Douma considered Kotoha beautiful, but very stupid. His mother loved to sing a lullaby for Inosuke, in which she only occasionally changed the words. One day, accidentally seeing what kind of things Douma really does, she ran in fear with her child into the forest. Pursued by the demon, she ran to a cliff, where she had to release Inosuke into the river, where he was later found by boars.

Inosuke is incredibly hot-tempered and reckless, often jumping into fights with stronger opponents without thinking about the consequences. He is competitive and often tries to provoke his comrades, Tanjiro and Zenitsu, into duels. Growing up alone in the mountains, Inosuke has difficulty communicating with others and is unable to read or write. Through becoming a Demon Slayer and gaining friends and allies, Inosuke has learned to spend more time thinking about strategies, analyzing his opponent, and assessing risks, as well as accepting help. Inosuke is quite vengeful, especially when people he cares about suffer. He was convinced that the machinist who stabbed Tanjiro did not deserve to live. He immediately attacked Douma after learning that he killed and devoured Shinobu, and he became truly angry when he learned that Douma was also the one who orphaned him. Most notably, he did not hesitate to challenge Muzan, demanding atonement for the numerous deaths of demon slayers.

Because he was raised by boars, Inosuke has a poor understanding of how to behave in society. He initially considers anyone who approaches him an enemy. He also does not understand the kindness with which other people treat him. Inosuke cannot read or write, and he has difficulty with human names: instead of Tanjiro, he says Monchiro, instead of Zenitsu, he says Monitsu. Sometimes, Inosuke can be too rude, but not intentionally.

Inosuke is usually seen wearing a mask and bare-chested. Without the mask, one can see that he has a beautiful, feminine face, thin eyebrows, large green eyes with long eyelashes, and shoulder-length black hair that turns blue. As noted by other characters, his soft features contrast with his muscular frame. Of the standard Demon Slayer uniform, Inosuke wears only dark blue pants, secured with a wide wool belt and finished with blue wool socks with bare toes and heels. The most important element of his attire is a light gray boar mask.
