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?
