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. This often leads him into unnecessary danger, since he tends to overestimate his abilities in comparison to who he's fighting and refuses to accept when he's been defeated, which can be seen when Giyu Tomioka has to tie him up after his fight.
