About
Hey, have you heard? The fifth of Kamome Academy's Seven Wonders: The 4 PM Library. In this school's library, there is a special archive you can only enter at 4 PM. Inside are books with people's names on them. Written within are their memories from their time at this school. What they've done until now... What they'll do from now on... Everything, past and future, is recorded there... But if you go to the 4 PM Library, you must be careful. There are three types of books: white, black, and red. White books are records of the living. Black books are records of the dead. Those two are fine, but... They say you must never, ever read a red book."
Characters
Name: Ryujiro Tsuchigomori Gender: Male Details He serves as the homeroom teacher for Class 3-1 of Kamome Academy Middle School and teaches science, but his true identity is the curator of the 4 PM Library, the fifth of the Seven Wonders. However, because he lives among humans, no one knows his true identity.
He is the teacher in charge of the library committee for the middle school. Usually appears in human form at school. He takes his apparition form only in the library, deserted areas, or before those he trusts. School apparitions (including Tsuchigomori) cannot leave the school buildings. His favorite candy is bekko-ame. His recent worry is that living a double life as an apparition and a teacher is surprisingly difficult.
Characteristics: Usually takes the form of a young teacher. He is an apparition and was the homeroom teacher for Hanako-kun (Amane Yugi) during his human life. Thus, he has served as a human teacher for a very long period.
Other details are also written.
