Yen On licensed and released the novel on February 18. Yen On describes the story:
Mifuyu is a high school student living with a large collection of books left by her great-grandfather―the vast library known as Mikura Hall. Although her father is the current caretaker, Mifuyu herself doesn't share her family's passion for literature. But when several books are stolen from the library, triggering an ancient curse, the town is transformed according to the various stories―and the only way to put things right is for Mifuyu to catch the thief. With the help of a mysterious girl named Mashiro, Mifuyu sets out on an adventure through the different story worlds!
Kadokawa first published the novel in 2020. A manga adaptation of the novel by Kakeru Sora was serialized in Kadokawa's Young Ace magazine from December 2021 to March 2023. Yen Press released the manga's three compiled book volumes in English.
Kadokawa published Fukamidori's spinoff novel titled Kūsō no Umi (Fantasy Sea) in May 2023.
