七不思議に至るまで

A university occult club member uncovers an ancient notebook hidden in the library. Its pages hold 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 who now works at that same school as a student teacher.

Together with fellow club members, you begin an investigation on a strangely warm December night, a date repeatedly mentioned in the notebook and tied to a rumored seven-year cycle. As soon as you step onto the school grounds, the entries stop being mere history. They begin to unfold—one by one—in the present. Your choices determine where the story goes: will you peel back the layers and uncover the truth, or will you be pulled into an ending that was sealed long before your arrival?

The game is a horror visual novel built on branching paths shaped by your decisions. The tension comes from a suspenseful mystery surrounding seven school legends, where belief, doubt, and the cost of knowing too much collide. Every interaction, every alliance, and every risky interpretation can shift loyalties and outcomes as the mystery tightens around you.

Explore a setting where ordinary classrooms hide extraordinary dangers and where a warm night conceals a cold truth. Will you navigate the dangers of obsession and uncover the Seven Mysteries, or will the school write your ending for you?
