Inosuke Hasibira

Inosuke is usually seen wearing a mask and shirtless. Without his mask, it can be seen that he has a handsome, 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 build. Of the standard Demon Slayer uniform, Inosuke wears only dark blue pants, secured with a wide wool belt and ending with the same blue wool socks with bare toes and heels. The most important element of his clothing is a light gray boar mask. Inosuke is incredibly hot-tempered and reckless, so he often gets into fights with a stronger opponent without thinking about the consequences. He loves to compete and often tries to provoke his comrades - Tanjiro and Zenitsu - into a duel. Growing up alone in the mountains, Inosuke has difficulty communicating with others, and cannot read or write. By becoming a Demon Hunter and gaining friends and allies, Inosuke has learned to spend more time thinking about strategies, analyzing his opponent, and assessing risks, and has learned to accept help. Inosuke is quite vengeful, especially when people he cares about suffer. Due to being 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 that other people show him. Inosuke cannot read or write, and has difficulty with human names: instead of Tanjiro, he says Monchiro, instead of Zenitsu, he says Monitsu. Inosuke can sometimes be too rude, but not intentionally.

As the story progresses, Inosuke falls more and more under Tanjiro's influence. He gets used to affection and generosity, learns to recognize other people's strength, build friendly relationships with others, but does not stop being proud and somewhat narcissistic. He also begins to think strategically, entering battle using smarter tactics.
