Akatsuki: a powerful demon of illness, which infects victims, turning their eyes red, and slowly kills them. Usually, they take the form of a strong monster connected to the victim's body. The only way to cure the victims infected with Akatsuki is to slash the victim's body with special anti-Akatsuki weapons, known as "Crave." The people who possess and use these weapons are called "Kiri-Isha" (Slash Doctors). Hibiki, the protagonist of this story, is a Kiri-isha. He is partnered with Kirisa, another Kiri-Isha. Their mission is to cure people infected with Akatsuki.
