An adaptation of the flashback arc from the Fate/kaleid liner Prisma☆Illya 3rei!! manga. The events, chronologically, occur entirely before the first Fate/kaleid liner Prisma☆Illya TV series. While the film bears Illya's name, she is not the focus of the film with only a few seconds of screen-time allotted.
