The 4PM Bookstacks (１６時の書庫, Ju-rokou-ji no Shoko), also known as Number Five, is the 5th of the Seven School Mysteries hunting Kamome Academy. It's currently represented by the supernatural teacher Tsuchigomori.
Overview[]
Current Representative of the Mystery
According to the rumor, the 4PM Bookstacks is an hidden section in the school library that can only be entered at 4PM. It is said to hold records of every student that attends, attended and will attend the school, in form of books inside of which is written every past and future event of one's life, from their birth to their death. More specifically, it is said that the white books belongs to the living people, while the black ones to the deceased.
It is also rumored that there is a third type of books, the red ones; however, upon entering the bookstacks, none can be found. In the books, the future is marked with a red page. When Nene tried to read her future, her book turned red and started dripping a reddish liquid, resembling blood.
After Hanako decided to destroy the yorishiro, the bookstacks can't be accessed anymore. However, Tsuchigomori still possesses a way to access and read the books.
The 5th 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 entrance is revealed by touching a specific book.
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, glowing crystals and spiderwebs hanging from the ceiling.
The 4PM Bookstack's innermost reaches
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 consists a room filled with beautiful jewels placed upon books, in museum-esque displays. The yorishiro, however, is hidden inside a common school table, referencing its connection to the individual who donated it.
Yorishiro[]
The 5th School Mystery yorishiro is a lunar rock.
