Misaki Hiro is normal student without any special trait or talent. One day, he is suddenly sent to a different world filled with magic by a mysterious goddess. His first meeting in the new world is with Eros Strobel who is student of all-girls magic school. Since his appearance overlaps with her summoning magic, she treats him as her familiar and has him stay at the school. There he meets up with her friends: the lazy senior human-beast Hibiki Flamel and stoic but kind Melusine Dragonette from the Dragon tribe. Later, at the same time when he knows about the trio is actually useless students who can't use magic, the girls also realize his special ability that they can use magic when holding hand with him. They welcome him to their "Soundless Club" as savior with expectation that things will change from now on.

When Hiro Misaki steps into a convenience store to grab a late-night snack, he finds himself transported to another world. “You have been chosen. As the hero who will save this world—” Summoned as the familiar of Eros Strobel, Hiro enrolls at Animate Girls’ Academy, a school specializing in magic. Eros Strobel: A noble-born witch who can’t use magic. Melly: A laid-back, easygoing dragon mage with no sense of urgency. Hibiki Flamel: A kemonomimi alchemist who’s always holed up in her lab. With nothing but girls around him, Hiro’s new life in the magical world of Partition is filled with all sorts of… unavoidable situations.
