Based in the present day Tokyo, there exist people known as Mahou Tsukai (people who use magic or "Mages"). But, even though there`s magic around, there`s not much difference from the world we live in.

Yume Kikuchi is a 17 year old 2nd year senior high school student. So that she can officially become a Mage, Yume makes use of her summer break and leaves for the capital from Tooya in the Iwate prefecture. It`s the first time she`s been to Tokyo. First time she`s been to a boarding house. And she was thinking that it`ll be an all girl`s place too but in fact, the manager`s a charming male. Caught in a mix of anxiety and great anticipation, Yume`s training in magic begins.
