Synopsis: Akatsuki

Akatsuki, a formidable demon of sickness, infects its victims causing their eyes to turn red and ultimately leading to their slow demise. Often, it takes on the shape of a monstrous entity that is linked to the victim's body. The only hope of saving individuals afflicted with Akatsuki is through the use of "Crave," unique weapons specifically designed to combat this malevolent force. Those who wield the weapons are known as "Kiri-Isha" or "Slash Doctors." In this tale, Hibiki is the hero, and he is one of the Kiri-isha while Kirisa is his partner. Together, they are tasked to cure those afflicted with Akatsuki, but what perils await them on their journey?
