Fate/kaleid liner Prisma Illya 3rei!!

Illyasviel “Illya” von Einzbern wakes to an unfamiliar, parallel Fuyuki City—alone, disoriented, and met with a hometown reduced to ruins. A vast crater scars the center of the city, and snow drifts down despite it being summer, leaving the young schoolgirl with no sign of her friends or her wand, Ruby.

At the remains of her home, Illya is suddenly knocked over by a mysterious girl in a gym uniform who can’t remember who she is or how she arrived. Calling herself Tanaka, the stranger may still hold a crucial lead on Rin Toosaka, Miyu Edelfelt, and the others who have vanished. With the Ainsworth family’s agents closing in—the rulers of this warped world—Illya and Tanaka are forced on the run, searching for answers and a way to reclaim the reality Illya once knew.
