Eerie school halls. A missing sister. A haunting mystery.

Play as Yui, searching for her sister Reiko in an ordinary school that hides an unsettling alterworld. Use a unique tuning device to unlock doors, solve puzzles, and shift between worlds. But be careful—the deeper you go, the eerier it becomes.
