Discover them before they learn your name.

Misakihama appears to be a quiet coastal town caught between nostalgia and the sea. At night, its streets reveal a reality controlled by corrupt police, criminal gangs and laboratories that pushed human experimentation too far. Behind every disappearance, impossible memory and altered file, the same name appears: Aster.

A call from your past brings you to the island. Create your own investigator, choose their class, history and personality, then confront eight supernatural cases whose order changes with every playthrough.

Every manifestation hides an origin, a true name and two weaknesses. Follow omens, question witnesses, inspect scenes and perform rituals at the shrine. What you learn may become your decisive advantage—because brute force is rarely enough.

Resolve all eight cases. Discover what Aster did. Decide how much of yourself you are willing to lose.
