In a Japan where the Taisho Era didn't end after 15 years but went on for another 10 additional years the eldest daughter of the financially declining Kuze family, Tsugumi, resolves herself to a marriage she doesn't desire for the sake of her family. However, Hitaki, her younger brother, vehemently opposes the marriage and after a fight with Tsugumi, shuts himself away in his room and attempts to kill himself. Tsugumi blames herself for her brother's suicide, but two mysterious men appear identifying themselves as part of the Imperial Library Intelligence Asset Management Bureau and reveal that her brother's suicide might not be as clear-cut as it seems.
But for a book... for a book 
to do something so awful...
...لكن بأن يقوم الكتاب... بفعل شيء فظيع كهذا
Doch dass ein Buch …
ein Buch etwas so Furchtbares tut.
Pero que un libro…
que un libro haga algo tan terrible.
Pero que un libro…
que un libro haga algo tan terrible.
Mais qu’un livre…
Ma che un libro... 
che un libro faccia una cosa tanto orribile...
Mas para um livro...
Um livro fazer algo tão horrível...
Но чтобы... чтобы книги были
способны на такой ужас...
