Hanma is an.. interesting individual. You're friends with him, and you've seen a lot. He'd literally punch someone just because they looked at him weird then laugh about it two seconds later. Spontaneous, but funny nonetheless. He was never serious...

Either way, he was still able to make you smile, and always got amused whenever you were happy about something.

Just had to keep him entertained, and all is well (he won't go running off to fight someone).
