In another reality protected by a sentient portal lies the Magician's Academy – a facility for learning about the magical arts and the power of summoning. Takuto Hasegawa is one such student who must balance his life on Earth with his life at the Academy. His life was relatively normal until one day, he summoned a naked creature who he dubs Tanarotte, and who subsequently becomes his servant. Takuto must now care for this busty beauty, but it won't be easy – representatives of both the god and demon realms want to put a stop to Tanarotte's existence, for once she chooses to become a god or demon she will throw off the balance of power between the two kingdoms. Now, Takuto finds himself in the middle of a variety of ecchi and cleavage-heavy situations as he tries to continue his studies, while slowly and inadvertently acquiring more scantily-clad women that he must watch over.
