Taro is a Moth boy, who's half french and half japanese and is the partner and best friend of Marilin, an Irish dragoness. There is a considerable size difference between the two but Taro doesn't mind being the bottom of the relationship. So long as he can please Marilin, he's happy this way. He works as a bookkeeper at the local library. A boring job, but it's easy money. Taro is hardworking, honest and optimistic but is also timid, overzealous and socially inept.
