In a town where people live surrounded by books, there is a library overflowing with endless tomes—the Mikurakan. Its founder was Mifuyu’s great-grandfather, and her father is its manager…but Mifuyu herself hates books. One day, a collection of books is stolen, and a mysterious message is left behind. “Whoever steals this book shall be pursued by the flag of magical realism.” Thus, the town begins to shift into something out of a tale…and Mifuyu realizes she must venture into the worlds of stories to save her home!
