Hanma can be best described as an adrenaline junkie. His single purpose in life is to find excitement, taking to street violence as a means to relieve his intense boredom. However, he slowly sinks into apathy as he continues to win fight after fight without much resistance. It is for this reason that he eventually allies himself with Kisaki and cares little if the latter exploits him, as he finds exhilaration in following his plans.

As long as he can entertain himself, he cares little about the consequences or the collateral damage that is caused by his actions. This mindset extends even to himself as he has very little regard for the value of his own life.

Hanma is also sadistic and cruel, eagerly enjoying violence and taking active an active role in Kisaki's plans. Even gloating and enjoying the chaos caused by their crimes, sometimes reacting with euphoria at being at the center of battle and seeing people getting hurt through their schemes.
