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.
Despite his adoptive father's warnings that the girl found in the remnants of a destroyed city is too dangerous to be considered anything other than a tool or weapon, Shirou Emiya comes to treat Miyu as a younger sister. But when Shirou relaxes his guard and Miyu starts normal school, the Ainsworth family and their agents swoop in, kidnapping the girl with the goal of sacrificing her! Faced with the realization that Miyu's ability to do good will always be equaled by her capacity for destruction, Shirou must attempt to both rescue his adopted sister, and decide how to confront the threat that her powers will always pose.
