This triumph is short-lived, as Miyu is abducted and carried away into the parallel universe by the Ainsworth family. Illya and her friends travel to the parallel world, where they join forces with Tanaka, an amnesiac girl whose goal is to defeat the Ainsworths; Gilgamesh, who wants to reclaim his Class Card from the Ainsworths after being defeated by Illya; and a parallel Shirou Emiya, Miyu's older brother who is imprisoned by the Ainsworths. The Ainsworths disclose their plan to use Miyu as the Holy Grail to save their dying planet, but Illya vows to save the parallel world without sacrificing Miyu. The Ainsworths flee following a conflict, and Gilgamesh departs the gang after retrieving his Class Card.
