The Girls Who Come and Go in My Library in a Crossover World

This is a library where all the books in the world eventually end up, and also the final resting place of every book.

Girls from other worlds often make their way here through the libraries in their own worlds.

Mai Sakurajima, who suffers from Adolescence Syndrome.

Nanase Kotobuki, the Literary Girl.

Dantalian, known as the Black Book Princess.

Index, the Magical Index.

And all sorts of other girls.

More or less, it's an everyday-life crossover story with a harem, but no womanizing.
