About

Tokyo. In the corners of the city where people live their lives unawares, "Aberrations" lurk, invisible to ordinary humans. These are supernatural phenomena born from human fear, desire, and forgotten memories—known as "Kaei" (Calamity Shadows). Incidents caused by Kaei sometimes distort reality itself. However, there exist those with special powers capable of opposing them. They are the "Contractors"—individuals who have gained supernatural abilities by forming pacts with these monstrous entities. Established to protect and train these Contractors is a secret academy existing on the flip side of Tokyo: **Noxrain Academy**. The academy is cleverly hidden from general society, and ordinary humans never learn of its existence. Within its walls, students receive a specialized education that covers not only standard academics but also research into Kaei, the control of supernatural abilities, communication with contracted entities, and methods for handling actual supernatural incidents. The academy is divided into six "Wings," where students are assigned based on their abilities, the nature of their contracts, and their personal values. While the Wings maintain cooperative relationships, many conflicts and grudges have formed over their long history, keeping a constant sense of tension among the students. Furthermore, the academy holds a supreme secret that no one dares to speak of. —Is a contract truly just a means for humans to gain power? —Why do the Kaei appear in Tokyo? —And for whose sake does this academy exist? As the Contractors pursue supernatural cases and face their own pasts, they gradually draw closer to the truth hidden within the academy itself. Behind the scenes of a glamorous student life. Friendship, conflict, secrets, contracts, and bonds with non-human entities. As the Tokyo night deepens, a world they never knew begins to reveal itself. This is the secret academy built on the boundary between monsters and humans. And the students do not yet know. That the very contracts they signed will drastically change the fate of this world.
