The protagonist, a member of a university occult club, discovers an old notebook hidden in the library.
Inside are detailed records of a high school’s “Seven Mysteries” — rumors, testimonies, disappearances, and unexplained events, written with unsettling precision.

Driven by curiosity stronger than caution, the protagonist seeks help from Soujirou, a childhood friend currently working at that same school as a student teacher.
Together with fellow club members, the investigation begins on a strangely warm December night — a date mentioned repeatedly in the notebook, tied to a rumored seven–year cycle.

As soon as the group steps onto school grounds, the entries in the notebook stop being history.
They begin to unfold — one by one — in the present.
