サンタ

Little more than a punk with silver hair and a bad attitude at first glance, this clever guy keeps pushing forward and doesn't like dealing with indecisiveness. His bracelet number is 3 so his name comes from "san", the Japanese word for "three" and that he references Santa Claus several times.

In reality, Aoi is the co-mastermind of the game, working alongside his sister, Akane Kurashiki. His bracelet number appears to be 3, although his true value is 0.
