The door once again told Yuma to open it, which he did using the Emperor's Key. When it was opened, Astral was released, but some shock caused Astral's memories to break into 100 [[blank card]]s. Astral was then fused with Yuma. While Yuma was being combined with Astral, he saw the one-hundred blank "Numbers" around him in a [[Sphere Field|sphere]].
