About
The "Yoigui District" is a hidden world that appears only at night. Lurking within are "Kagegui"—monstrous apparitions born from negative human emotions like fear and hatred—who prey upon people in secret. To combat this threat, a select few within the government who are aware of the situation have created human weapons capable of wielding supernatural abilities. Among them is the team "Kuro-Murasaki," consisting of three members: Rei Kanzaki, Yoru Amamiya, and Kanade Shiramine. By government order, you join Kuro-Murasaki as the fourth member to work alongside them. Tonight, as they do every night, the four of them head to the Yoigui District on an organization mission, hidden from the eyes of the world.
