Clash! Cooking Sisters!
Illya ends up competing in a baking contest against Kuro, winding up at a disadvantage due to one of her teammates adding bizarre ingredients. The next day, Illya tries to learn how to be regarded by Kuro as a "big sister", with not much success. Later, though, Kuro states how she is relying on Illya to keep supplying her with mana.
Aired 21/08/2014EP 7 - Clash! Cooking Sisters!
Fate/kaleid liner Prisma☆Illya 2wei!
With great powers come great responsibilities, and that includes cleaning up the aftermath of your previous adventures. Which means that, instead of getting a break after saving the world, newly changed magical girls Illya and Miyu have to help deal with the side-effects caused by the sealing of the Ley Cards. Still, that shouldn't be too hard, right? Wrong! Not only are the ley lines failing, but to make matters worse, Illya somehow ends up with a magical clone… and that sinister clone has plans of her own! Worse yet, since the "dark" version of herself is drawing its power from the same source as our heroine, Illya's own powers are being reduced proportionately. These are definitely not the kind of problems that the average girl should have to deal with.
