Kuzuryuu Fuyuhiko

Fuyuhiko is the heir to the Kuzuryu Clan, the largest organized crime syndicate in the nation with a membership of over 30,000 people. When it comes to the criminal underworld, he's the real deal. Fuyuhiko hates crowds and refuses to get along with anyone, as indicated by his salty attitude and foul mouth.
However, it's possible that he's only acting like that on purpose. Though Fuyuhiko has a youthful appearance, do not under any circumstances comment about his cute, baby-like face. You will run out of fingers before he is finished with you.
