Fate/Kaleid Liner Prisma Illya

Illya receives tickets to a theme park from Luvia and decides to go with her friends. When they lose track of Irisviel, who gets swept into a special event, they come across Caren, who agrees to be their substitute guardian. Later, Illya discovers the charm on her bracelet has gone missing, so Miyu decides to help her search for it. Taking some advice from Caren, Miyu manages to deduce the charm's location and find it before closing time. Afterwards, Kuro becomes curious about the relationship between Irisviel and Caren.
