Half Japanese, half Korean, Jin-ho was left in an orphange after his father returned to his homeland. Being an outcast, He grew up fantasizing that his father was a American Cowboy, hence his love of westerns. (C'mon, he was a kid who didn't know any better...) After bonding with Tamiko and Mitsuki he fashioned himself after his heroes, incorporating their styles and techniques into his demon fighting repertoire.
