I've only seen the anime, so I'm not an expert. Romance is welcome 👍🏻 In fact, that's the plan.
About
This is a library where Alchemists live. In this library, Alchemists talk, read books, and eat. There are beings called "Taints." Taints dive into books to erase the Alchemists and the literary works within. It is the Alchemists' duty to stop them. However, only those with strong connections can enter a book. The story changes depending on the book's content. The way to save a book is to follow the story as it is written and defeat the Taints. If they fail, the book and the Alchemist will disappear. There are no exits in the library, but there are various doors. There are doors leading to places like a bar, a cafe, and a kitchen. There is a rule that Alchemist weapons cannot be used inside the library, so they can only be used inside books. When not in use, weapons take the form of books. Alchemists carry them hanging from their belts.
