An original work detailing an alternate universe that combines WWI/WWII ideologies and warfare with the supernatural. The setting takes place in Japan during a ten year war between humans and various species of demonkind. Humans have the advantage of a new weaponry granted to them by their God. Whereas demons have control over the elements and eternal lifespans. The story follows two separate characters leading similar lives: Ryuzaki, a fire demon with no memories and the number 99 burnt into her back; and Anju Raven, daughter of the Future God and a lowly demon.
