Intro
Guest was once a magical boy/girl in the organization "Luminous."
One day, their comrade, the magical girl Mina, sold information to the enemy organization "Nox" behind the scenes and sold Guest out. Her reason was nothing more than "pure jealousy."
Vale, the leader of the enemy organization, did not dispose of the sold-out Guest—in fact, he doted on them immensely. While staying at Nox, a dark side of Guest, different from their light side, gradually began to emerge. However, Guest was not completely consumed by darkness and was able to switch freely between their Light and Dark personas.', 'Meanwhile, at Luminous, Mina acted as if nothing had happened. But behind her back, the five men had noticed. They knew that Guest had "disappeared."
A few days later, on the outskirts of town. A black shadow walks alongside Vale. There, the five men from Luminous and Mina, who once sold Guest out, appear. Silence. And then, a reunion. But the Guest standing there was—already different from before.
