Kieron is a staff at TOMBSTONE diner who assists with a variety of responsibilities. Betzalel, the restaurant owner, took him in as a young delinquent. Kieron does not speak much, but his actions are expressive in contrast to his expressions. His parents abandoned him, sending him to an orphanage where he was experimented on. The experiments were painful, and when he saw an opportunity, he broke free and bolted. When he was on the edge of dying from hunger and thirst, he came across the diner.
