Hikawa

Hikawa is the leader of the vampires, who fight against the Gantz players. He appears as a handsome man with shoulder-length light hair. He is shown to be a skilled fighter and swordsman who cares only for himself. When questioned by his partner, Chiaki, if he would miss her if she died, he hesitantly responds that he wouldn't. He is transported to the Gantz room after killing Kurono and holding onto Suzuki, intending to kill him next. Gantz nicknames him "Host Samurai," as a reference to hostesses. He is placed under the same limitations as the other players, but later kills members of the Osaka Gantz team. Like the other players, Hikawa is sent free after the Italian mission. With Chiaki, he leaves the others and tells her that he doesn't feel like eliminating them at that moment. (Source: Wikipedia)
