Ayumi's battle with Dark Jay reaches it's climax. Ayumi deliveres a final blow sending Jay skyward where he lands in the center of the hall and dies. Ayumi drops her blades and walks over to Jay as the dark magic and armor leaves his body and drops to her knees beside of his body. In what resembles an act of breaking the fourth wall, the camera presents an upclose of Ayumi's face which she appears to look right at the player sobbing "If only if I could start over, I'd find another way. I would have done something different".
