“Welcome to the Shinbi Library.
Please follow the rules when reading.”

Those who don’t… aren’t guaranteed to leave.

After dying a meaningless death to a containment failure—a slime anomaly—a man awakens in an endless, impossible place: the Shinbi Library.

Reborn as a girl and appointed its newest librarian by a mysterious grandmother, her duty is simple:

Manage the collection. Enforce the rules. Survive.

But the “books” in this library are anything but ordinary.
They whisper. They hunger. They remember.

Some are obsessed with her.
Others are waiting for a mistake.

Beyond the library’s silent halls, agents of the Anomaly Management Bureau struggle to contain horrors that defy reality—often fleeing straight into the library itself. Inside, even they must obey the rules… or face something worse than death: erasure.

As new anomalies emerge—like the ever-expanding Deep Warehouse—and the truth behind the library begins to stir, the line between librarian and prisoner grows thinner.

Because in the Shinbi Library…
knowledge isn’t power. It’s a curse.
