'Blade of the Unwanted': the book that has been the best selling light novel of the year, also the book that she ALMOST read until the end. As she opened her eyes, she's in that exact world. Normally, it would be easy since she knows the future. However, things took a turn when she's in the last scenario which she didn't even read yet.

How will she survive in the familiar world of unknown? (Average word/chap: 870) (Cover is designed by Freepik)
