Fuyuhiko Kuzuryu is the Ultimate Yakuza.

Fuyuhiko is initially incredibly stand-offish and rude to the other students on the island. He claims he's not going to play at being friends with anyone, and when he is questioned about this, he states clearly that he would not hesitate to kill anyone of the others. He makes frequent references to his yakuza background and seems adamant at presenting this sort of "lone wolf" attitude.  As the game progresses, however, he slowly begins to open up to the others.

His official English voice actor is Derek Stephen Prince
His voice should probably be mid to mid-high. Also, he swears more than any of the other characters, so if you don't like swearing, this may not be the role for you...
