As a high school student, Keisuke Sotoki has always had bad luck. He hopes something will change until one morning, he wakes up naked with an attractive man on top of him, demanding his "rear end." Shockingly, the man is Mahara, the crown prince of Latula, who identifies as a magical being known as a "magus." Mahara believes that their fates are entwined and only by teaming up can Sotoki end his unlucky life. Unfortunately, there is a complication: Sotoki and Mahara are both heterosexual, and only Sotoki can see Mahara. What will happen next?
