Normal Life Breaker
After failing to get any information from Kuro, Rin places a seal on her that would cause her pain if anything happens to Illya. When Kuro escapes, Illya has to take drastic measures to keep her from making moves on Shirou. The next day, Kuro causes more problems for Illya when she starts randomly kissing other girls at school to replenish mana. When the two are spotted together by her classmates, Kuro decides to pose as Illya's cousin.

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.
