One day after school, the half-youmu boy, Akihito Kanbara, meets a girl who looks as though she is about to jump off the roof at any second. Her name is Mirai Kuriyama. She is the last surviving member of a clan that has a blood curse that is unique even amongst the Under World Warriors. Yet, the moment that girl survivor met the half-youmu boy, his world changed completely.
