Magical Girls? Wait, Why Is This a Training Academy for Female Demons?!

Seven days! Conquer 27 female classmates! Raise their affection to at least 60 (willing to be friends)! Otherwise, you'll be forced to... With one hand on his crotch and the other holding a "picture of Sister Yu," pale-faced and blissful... die in bed? "That's the mission you gave me!?" At that moment, Nangong, the only male student in the entire Magical Girl Academy, couldn't help but question his [World's Strongest Martial God Training System]... No, wait, it had already become female, so it should be called the [World's Strongest Conquest System] now... [World's Strongest Conquest System]: That's right, Host! Let's work hard toward our grand goal: if you can't be the world's "strongest man," then become the "world's strongest man"! Screw you!!!!!
