A Hat, Ice, and a Princess

Aoi and Itsuki are chosen to play the prince and princess in a class play for the upcoming cultural festival. After encountering Minato again, Subaru hears from Itsuki about how, when she was younger, she got herself in an accident for which her brother got blamed, which led her to be conscious about causing people trouble with her own desires. Just then, as another fragment appears, the girls wind up on Saturn's rings, where they are once again confronted by the cloaked boy.
