Spoilers abound. The final boss from Fatal Frame 2: Crimson Butterfly (Project Zero II). Played on a blind (first) run through the game. It all ends here, the climax before the end and our rescue of Mayu. Can Mio do it? In the deep underground passages below the big house, we find the *** (Hellish Abyss) and Seijiro Makabe, who has been made into a Kusabi (our final boss).
