Rei Kirishima, once a rising detective known for his sharp mind and unrelenting pursuit of justice, vanished on the 7th birthday of his daughter, Aiko. His wife, Yukari, searched endlessly — until news broke that both she and their daughter were found murdered. Footage showed Rei, bloodied and deranged, supposedly committing the crime.

But Rei was never free. He was locked in a sealed room, force-fed the lie that he had killed them, driven to near madness. For seven long years, his only companions were a television screen, an endless mirror, and a diary.

Now freed, Rei must find the man who destroyed his life. He doesn't know if he's chasing justice — or vengeance.
