Inosuke is an extremely short-tempered and proud man who 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. He can't read or write, and struggles to say peoples names right often replacing the first letter with a "m" or adding "chiro" at the end. Inosuke is extremely flexible to the point where he can bend backwards so far that his head reaches between his feet.
