Plot
Louise and her gang accepted a request from Queen Henrietta, to exorcise the spirits hidden within a prestigious library. Due to the delicate nature of the books and the prospects of an adventure the gang agreed to intervene.

The gang knew that they are going to encounter spirits, but they never thought they would encounter the large amount of unfinished magical books.

Intending to give themselves an ending, these volumes seek the dormant power within Loiuse. Upon her entry, the proud but shy girl has her heart taken, split into small pieces and seeped into the books. To rescue his friend and summoner, Saito has to enlist the help of his classmates and enter the world of these texts.
