Current Representative of the Mystery
Shijima-san of the Art Room is the fourth of the School Mystery. It is the sixth school mystery to be introduced in the series, making its debut in Volume 9.
Shijima Mei is capable of creating picture worlds that reflect wishes deep within people's hearts. Once you've been pulled into her world, you'll have to follow her words or you'll remain trapped. The longer you stay in the fictional world, you'll slowly forget about your original life.
It is later revealed that there is an emergency escape within the world, usually placed in an area the main character will never be able to reach. The escape changes frequently, but at the time of the escape, it was placed within the moon, reflecting the desires of Hanako.
The aspect the Fourth School Mystery oversees in Kamome Academy is currently unknown.
The boundary is located in the Atelier tower, the same one that was drawn by Shijima Mei in her final painting. The painting itself is placed in the Kamome Academy's art room.
The Atelier tower is a tall structure with mismatched floors and winding stairways. On the lower levels, there appears to be a museum used to showcase Shijima's artworks. On the penthouse is studio the School Mystery uses to create paintings, filled with art equipment. There is a balcony overlooking the world inside the painting.
The Yorishiro of Mystery No.4 is a sketchbook.
