Mizuki Nomura is a Japanese author born in Fukushima Prefecture. She graduated from the literature department at Toyo University. Her professional writing career began in 2001 when she won the third Entame Grand Prize in the novel category for her debut work. This award served as her entry into the world of light novels, where she has since become a well-regarded figure.

Nomura is the original creator behind the Bungaku Shōjo franchise. This series of light novels, whose title translates to Literature Girl, forms the foundation for the various anime adaptations she is credited for, including the film Bungaku Shōjo and the OVA series Bungaku Shōjo Memoir. The story centers on Tohko Amano, a self-proclaimed Book Girl who is a member of her high school's literature club and has the unique ability to consume and digest stories by eating the paper they are printed on. The series follows Tohko and her fellow club member Konoha Inoue as they become entangled in mysteries related to the literature they love.

The Bungaku Shōjo light novel series, illustrated by Miho Takeoka, was published by Enterbrain under their Famitsu Bunko imprint. The main series consists of eight volumes released between April 2006 and August 2008. This was followed by four short story collections, four side story novels, and a separate concluding volume, bringing the total to sixteen books. The series has been licensed for English release in North America under the title Book Girl. Beyond the core novels, the franchise expanded into a manga adaptation, which was illustrated by Rito Kōsaka.

The Bungaku Shōjo series is the defining work of Nomura's career and represents a significant departure from her earlier writing style. Her earlier works from 2002 to 2005, such as the Table Tennis Court series, Bad! Daddy, and Usakoi, were more straightforward youth-oriented comedies. In 2006, she shifted her focus to create a story capable of conveying serious, heartfelt, and melancholic tones. The resulting Bungaku Shōjo series, which uses classic literature as a central plot device, earned her significant critical acclaim and commercial success, with over 2.5 million copies in circulation as of 2020.

A recurring hallmark of Nomura's artistic identity is her use of pre-existing literature as a structural and thematic backbone for her original stories. In the Bungaku Shōjo series, each volume directly incorporates a famous literary work, including No Longer Human by Osamu Dazai, Wuthering Heights by Emily Brontë, and The Phantom of the Opera by Gaston Leroux. The plot and character development often mirror or directly engage with the themes of the referenced book, blending an original mystery with a literary homage. This technique demonstrates her deep appreciation for classic literature, which she has cited as a major influence, alongside the works of Louisa May Alcott, L.M. Montgomery, and Japanese writers like Ice Muromachi and Motoko Arai.

Nomura is known for her prolific writing pace and for completing her manuscripts well before deadlines. After a hiatus from publishing around 2016 due to health issues, she returned to writing in 2020. Her significance in the industry lies in the success and influence of the Bungaku Shōjo series, which remains her most celebrated and best-known work.
