Avid bookworm and college student Motosu Urano ends up dying in an unforeseen accident. This came right after the news that she would finally be able to work as a librarian as she had always dreamed of. When she regained consciousness, she was reborn as Main, the daughter of a poor soldier. She was in the town of Ehrenfest, which had a harsh class system. But as long as she had books, she didn't really need anything else. However, books were scarce and belonged only to the nobles. But that doesn't stop her, so she makes a decision... "If there aren't any books, I'll just create some."
