Inosuke is short-tempered, confrontational, abrasive and proud. He always likes to think he is the strongest fighter in a situation, constantly challenging most people he comes across and wanting others to respect and praise him for his skill. Due to him having been raised by boars, Inosuke has also been shown to possess little understanding of normal human interaction, at least at the time of his debut, he is a demon slayer and uses beast breathing. He wears a boarshead over his head.
