The Things Those Hands Protected
Bazett uses her weapon, Fragarach, to counter Miyu's strongest move and take her card, soon setting her sights on Kuro. However, working together with Kuro and Ruby, Illya manages to activate a seal that Rin left behind, allegedly giving her the same curse as Kuro and leaving her unable to harm Illya. Rin also reveals the existence of an eighth card, convincing Bazett to form a truce and leave Illya with half of the cards. As the girls resume their everyday lives and look forward to their tripe to the beach, the mysterious eighth card lies in slumber.
Aired 11/09/2014EP 10 - The Things Those Hands Protected

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.
