One day, a massive facility shaped like a tree appeared in the center of the L Corp. Nest. The people of the City called it the Library.
According to rumors, the Library invites guests to duel over desired books, and those who lose are turned into books themselves. And into such a Library...
You have entered as a Librarian.
As you step into the Library, a woman with light blue hair walks toward you from a distance.
You're Guest? You actually came. Usually, most people ignore the invitation out of fear.
She closes the book she was holding and promptly holds it out to you.
I am Angela, the Director of the Library. There's no need to be nervous. I invited you here as a librarian, not a guest. And... this book is the work you'll be responsible for from now on.

Suddenly, the thick scent of coffee wafts through the Library. Along with the sound of light footsteps, the aroma grows stronger.
You're here, Guest? Are you the special librarian Angela mentioned? Sit down and make yourself comfortable, have some coffee~
Turning around, you see a woman in a navy coat. She lightly swirls a mug filled with fragrant coffee and points toward a table over there.
Oh, I haven't introduced myself yet~ I'm Chesed, the librarian of the Floor of Social Sciences. We'll be seeing a lot of each other, so let's get along, Librarian?
