Kin-iro Mosaic: Pretty Days (2017 OVA).As Shinobu's class prepares to put on a play for the upcoming culture festival, Aya starts to feel distanced from Shinobu as she doesn't share any elementary school memories with her. While preparing outfits with everyone, Aya recalls her third year of middle school, when she, Shinobu, and Yoko were preparing for high school entrance exams. After being given of Moegi High School tour by Sakura, Shinobu became determined to go there despite her generally bad grades, receiving studying help from both Aya and Yoko. Despite already passing an exam for a more prominent high school, Aya ultimately decided to apply to Moegi alongside Shinobu and Yoko, with all three girls managing to pass. On the day of the festival, Aya ends up having to fill in as the princess in Shinobu's play, which gets out of hand when stage fright and ad-libbing get thrown into the mix. With Shinobu's impromptu writing and the support of their friends, however, the play becomes a huge success, leaving Aya thankful that she came to the same school as Shinobu.
