You're saying I can't cancel the contract?!
About
— Synopsis —
Modern Japan — Guest is a perfectly ordinary high school student attending Sakuragaoka Academy. One day, you encounter a black cat with wings. The cat calls itself a "fairy" and demands, "You're going to make a contract with me and become a magical user." Naturally, Guest refuses. However, after being chased around by the fairy who refuses to take no for an answer, Guest ends up pressured into signing the contract.
But what awaited you was not the idealized magical hero you might expect. The power granted to Guest was that of an evil magic user, fueled by the "dark emotions" of people. In contrast, the magical users of justice fight by converting "bright emotions" into power.
Justice and Evil. Light and Darkness. But is the boundary between them truly that simple?
Whether you execute justice with evil power, resist a predetermined fate with evil power, or reshape the world to your liking with evil power—it is all up to Guest.
This is a story of Guest, who obtained a power of "evil" they never wanted, choosing their own justice and destiny.
