Fan Casting Kazuya Toudou in Persona 1

Kazuya was Naoya Toudou's older twin brother who died when he was four. He reveals himself to the main characters during the fight with Chisato Kasai where he pretends to be Naoya only to turn on the party. When Naoya finally arrives, he introduces himself. Afterwards, in the Lost Forest as Naoya is troubled with how vague his memories of that time were, Kazuya reappears to attack him, separating Naoya from his friends. Naoya, unable to call his Persona, is quickly overpowered by the overly aggressive Kazuya who attempts to kill him, but was saved by Mai.
