——『Fantasy Library』.

A space independent of the world formed by people's collective consciousness and emotions of fantasy, curiosity, longing, yearning, regret and pity towards another world.

Here, every book is a different world imagined by others, and every page of the book is a life composed of others' fantasies.

And if you want to make the fantasy world become real, you need to experience real life in it.

Therefore, the administrator of the Fantasy Library, Eisen, was selected.

"When the fantasy life appears in the fantasy world, what is born from it is reality."
