The ties that bind are drenched in blood. Mirai Kuriyama, is the last surviving member of her cursed family. Akihito Kanbaru is the feared immortal half-youmu. Alone they are the outcasts in their society; together they're the oddball duo that can't get along.

But trouble is brewing in the Spirit World and Akihito and Mirai are getting caught up in the storm.
