By the time she has realized what happened, a mysterious girl who looks eerily like Illya appears, apparently bent on bringing destruction down on the original whose heart she seems to have spawned from, and making matters worse she holds the power of the Archer Class Card, with which Illya holds a special bond, within her body.
