This victory is short-lived, as Miyu is kidnapped by the Ainsworth family and whisked away into the parallel world. Illya and her friends enter the parallel world and teams up with Tanaka, an amnesiac girl whose goal is to defeat the Ainsworths; Gilgamesh, who wishes to take back his Class Card from the Ainsworths following his defeat by Illya; and a parallel Shirou Emiya, Miyu's older brother who is imprisoned by the Ainsworths. The Ainsworths reveal that they intend to use Miyu as the Holy Grail to save their dying world, but Illya swears that she will find a way to save the parallel world without sacrificing Miyu. Following a confrontation, the Ainsworths escape and Gilgamesh leaves the group after reclaiming his Class Card, while Angelica Ainsworth reluctantly joins the group after being left to die by her family and Miyu and Shirou are liberated.
