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. Your decisions determine where the story leads.
