No.5 The 4PM Bookstacks

Current Representative of the Mystery

「１６時の書庫」
The 4PM Bookstacks is the fifth of the Seven Mysteries. It is the third school mystery to be introduced in the series, making its debut in Volume 3.

The bookstacks have records of every student in Kamome Gakuen, from the past and even in the future. It is said that white books are for living people, and the black ones are for the deceased.

Upon entering the bookstacks, none of the rumored 'red books' can be found. But in the books, the future is marked with a red page. Nene was led by a butterfly to find her own book and read a bit of her future. After reading her future, the book turned red. A large figure that resembled her appears and stuck up to attack her.

The Fifth School Mystery oversees the "Records" aspect of Kamome Academy.

Boundary
Hidden in the Kamome Academy's library and only accessible at 4 o'clock in the afternoon is the 4PM Bookstacks' boundary. The door to the bookstacks is revealed by touching the book the butterfly landed on.

The boundary is a long, narrow library decorated with floor-to-ceiling bookshelves and tall rock columns. The bookstacks is noticeably dark, with a few floating oil lamps illuminating the area. In the manga, there were glowing crystals as well. There are spiderwebs hanging from the ceiling.

The deepest part of the boundary is hidden behind a bookcase. After a long walk through a cavernous area, the innermost reaches can be accessed. It is a room filled with beautiful jewels placed upon books, in museum-esque displays. The yorishiro however, is hidden inside a school table, referencing its connection to the individual who inspired the object.

The Yorishiro of Mystery No.5 is a lunar rock.
