About This Game

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.

Your decisions determine where the story leads.
Will you reach the truth, or fall into an ending sealed long before you arrived?

Features

• Horror visual novel with branching paths based on player choices

This is a story about curiosity, belief, and the cost of knowing too much.

Can you uncover the Seven Mysteries—
or will the school write your ending for you?
