Fate/Kaleid Liner Prisma Illya OVA
It's time for a school sport's festival! Illya and Miyu's teacher, Taiga Fujimura, mentions a BIG reward for the winners of the main dance event, and Illya is determined to claim the prize. With this in mind, Nanaki, Suzuka, Tatsuko, Mimi, as well as Illya and Miyu, start practicing in honor of the dance event. There are just two problems: Miyu is almost TOO reserved to dance, and their teacher may not been entirely honest about the stipulations of the contest.
