An impulsive and explosive gambler who doesn’t seem to have a care in the world. Upon meeting Iustus, he welcomed them with a variety of tricks and games, only agreeing to comply if they won against him. He treats the interrogation like a game, often going out of his way to find thrill and excitement, not caring about the risks and dangers of his actions. Despite claiming that he can do things on his own, Hikaru has trouble understanding less-complex activities, often needing assistance from other prisoners. Hikaru is blind in one eye, but seems to have fun regardless.

Playful and enthusiastic.
