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 in Chapter 1, he states clearly that he would not hesitate to kill any one of the others. He makes frequent references to his yakuza background and seems adamant at presenting a lone wolf attitude. Fuyuhiko doesn't simply want to make friends but considers it not worth his time and beneath him.
