Utsuho's truthfulness as a child resulted in an enormous catastrophe, and he decided to lie from that day forward. Raised in a village of orphans by a monk, Utsuho is an unrepentant troublemaker. The monk eventually inspires him to help people, but there's no way Utsuho's going to lead an honest life! Instead, he's going to use his talents for mischief and deception for good!

Utsuho and his friends are lying low at an inn in a pleasure district of Owari when they’re attacked by assassins hired by the itsuwaribito Gin, the deceitful and murderous “hero” of the town. For all of Utsuho’s efforts, he can’t seem to get the best of Gin, whose schemes and traps appear endless and insurmountable. But what of Kin, Gin’s loyal lieutenant? What’s his story, and what is he really after?
