Kitahara Shin is a student at Griladorse Magic School and is running late for class. He's helped by an unknown beauty who's flying on a broom. After reaching the school on time somehow, he's told that this student could be the new transfer student and he gets even more hyped up when he hears that this student might be one of those “magical girls.” But the transfer student is nothing but a cute, innocent-looking girl by the name of Nyui, who seems to have a thing for Shin. Is this girl really not the broom-flying beauty Shin was expecting? And what will she do with the school idol Shisune who Shin idolizes? Will Nyui’s Succubus-like devil friend, Yasuda, make the situation any better? [Midori-Mori]
