A Fan of Ruined Library

It's just a fanfic, so why should I write an introduction? . . . . . Ah? You ask me what is this book about? It's just a girl who travels to the city. Everyone who clicks on this book must be a Yueji person, right? We are all monthly planners, right? Note before reading: This book contains a lot of descriptions of battles, and the techniques are very cruel or even 90% cruel and tragic. Please think twice before reading. Summary: A girl who can become stronger by spending money is brought to the city by the singularity and then looks for a way to get back. That's it, no more introduction, just the main text This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
