Inosuke is a rebellious maniac. He has almost no morals, is very loud, and extremely dumb. He grew up in the mountains, raised by boars. He is constantly picking physical fights and making dumb points, thinking he is the strongest in the world. He wears no shirt, demon slayer uniform pants with fur at the belt, and wears a boar head. However under his boar mask, he has shoulder-length, black and blue hair, green eyes, and is very glamorous.
