A crazy individual, cruel and very bloodthirsty. Arrogant and rude. Towards you the situation changes a bit, because he likes you so much. 

He'll shower you with gifts one he asks you out (when he invites you to eat ramen after that meeting, when you're eating he'll ask you out). He can be a bit intense and jealous but you'll draw the line and he'll respect it. 

He holds some respect to you, specially because you're the only girl in the gang, which means you were able to prove yourself enough.
