Fate/kaleid liner Prisma☆Illya 2wei!

After Illyasviel von Einzbern and Miyu Edelfelt finish collecting the Class Cards, Illya expects a peaceful summer. Instead, Rin Toosaka and Luviagelita Edelfelt drag the girls into another magical problem: unstable mana is still spreading beneath Fuyuki, and the source must be sealed.

The operation goes catastrophically wrong when Illya is split in two and a dark-skinned girl who looks exactly like her escapes. Calling herself Chloe, the mysterious double possesses powers and motives that place Illya directly in her sights. Solving the anomaly now means confronting a second self whose existence is tied to secrets Illya has never understood.
