With the last of the Death Stones recovered, Ayame and her allies face off against the Eclipse Order in their stronghold, a dark fortress built atop an ancient, forgotten realm. Zarah, having gathered immense power, begins the ritual to summon The Devourer. The sky darkens, and the air is filled with swirling chaos as the world itself begins to break apart under the weight of the ritual.

In a desperate battle, Ayame uses the full extent of her powers to combat Zarah, but the dark magic of The Devourer is overwhelming. Zarah reveals that Ayame's very existence is the final key to the summoning—her breaking of the cycle was what began the process, and only her death will fully unlock The Devourer's prison.
