Fate/kaleid liner Prisma Illya - S02

A month has passed since Illya and Miyu became magical girls and secured all the Class Cards. Rin and Luvia are stuck in Japan, dealing with the lingering mess-including the unstable magic in the local ley lines. While helping with the cleanup, Illya’s hidden innate magic suddenly spirals out of control, disrupting her transformation. Before she can grasp what’s happening, a strange girl who looks almost identical to Illya appears, driven by a violent urge to destroy the original-the one whose heart she seems to have emerged from. To make things worse, she wields the power of the Archer Class Card, which holds a deep connection to Illya herself.
