Akatsuki

A condition known as Akatsuki causes illness in victims, turning their eyes red and leading to a slow death. It often manifests as a powerful creature linked to the infected individual's body. The only treatment involves using specialized weapons called "Crave" to slash the afflicted. Those who wield these tools are known as "Kiri-Isha." Hibiki, the main character, is one such practitioner, working alongside another Kiri-Isha named Kirisa. Their objective is to treat those affected by Akatsuki, though challenges remain ahead.
