Fate/kaleid liner Prisma Illya (2013) : 2x4

Kuro transfers into Illya's class, much to Illya's dismay, and is immediately thrust into a dodgeball match against the classmates she kissed the other day. Feeling her school life is at risk, Illya steps in to challenge Kuro one-on-one, with both sides bringing out their full magical power. Kuro lands a critical hit on Illya's face, but due to their shared pain they both pass out, ending the match in a draw. Whilst recovering, Kuro suspects the school nurse knows more about her existence than she lets on. As Shirou comes to pick up Illya, Miyu is a little perturbed by Kuro's words that she shouldn't stay too close to Illya, lest she find out things she has been keeping secret.
