In a world not unlike our own, mages are commonplace and schools are separated between normal students and magic users. Yuma Kohinata is a student at one such school, Mizuhosaka Academy. On the way home from buying chocolates with his androgynous friend Jun, Yuma is given chocolates from school idol Haruhi Kamisaka; things become even more complex once the magic wing of the school has a gas explosion, displacing all of the magic students into the normal section – including Haruhi! Now, Yuma finds himself thrust into the world of magic, and must deal with the various women who vie for his affections; can he juggle his priorities and continue to pass his classes?

Kasuga Rito had a hidden wish for a very long time: to use his ability for good and to help people. But before he could do that, he needed to gain the power of magic first. Rito is a sophomore in Rezon Institute, a school for people with special magic abilities to find, train, and develop their skills. Each student has to reach 100 points to be able to start using their ability. Otherwise they won’t move up from the “Common” and into the “Starlight” class. But Rito, known as “the Eternal 99”, has been stuck with an unchanging 99 points for a long time.
