A college student named Chie Souma is struggling with depression because she's unable to find employment. She had always dreamed of entering one of her favorite fantasy novels, but instead found herself lost in reality. Suddenly, the ground shook and she passed out. When she woke up, she realized that she was in a different world. In this new world, being a woman looked dangerous, so Chie decided to crossdress as a man named Souma. To her surprise, she discovered that she could read the language of this new world and began working as a librarian in a village.
