Märchen Mädchen (メルヘン・メドヘン, Meruhen Medohen; German for "Fairy Tale Girls") is a Japanese light novel series written by Tomohiro Matsu and StoryWorks, with illustrations by Kantoku. The series was being worked on by Matsu before his death in May 2016, and he is still credited as the writer.[2] Shueisha published four volumes between February 24, 2017 and April 25, 2018, under their Dash X Bunko imprint. A manga adaptation by Takatoshi Nakamura and Kiyotsugu Yamagata was serialized in Shueisha's Jump SQ magazine between October 4, 2017, and May 2, 2018. An anime television series adaptation by Hoods Entertainment aired from January 11, 2018, to April 25, 2019.

The series revolves around Hazuki Kagimura, a socially awkward high school girl who loves stories since childhood. Whenever her life with her new family doesn't play the right cards for her, she instead indulges into the stories she borrows from the local library. One day while returning, she finds a book which she doesn't recall borrowing. She later bumps into a strange, hooded woman who she recognises as the mage from her stories.

While following the woman back to the library to return her belongings, she finds her opening a portal into another world, in which Hazuki gets mysteriously sucked into. Waking up, she finds herself in a mysterious school which is unfamiliar to her. The hooded woman reveals herself to be Shizuka Tsuchimikado, who tells Hazuki that she is in a magic school where girls known as 'madchen' are chosen by magical texts from which the world's stories are born. She also tells Hazuki that she herself has been chosen by the book of Cinderella, and has now become a madchen. In order to master her new abilities and become a full-fledged mage, Hazuki must endure grueling tests and get used to the campus. Thus, her new school life, filled with fantasy and magic, begins.
