Während die vier älteren Mädels auf Klassenfahrt in Kyoto sind, merken Azusa und Ui, wie einsam sie ohne Freundinnen und Schwester sind. Gemeinsam mit Jun versuchen sie, das Beste aus der Situation zu machen.
Azusa and Ui, along with their classmate Jun, spend time together while the third years are on their trip to Kyoto. Noticing that Ui would be lonely without her sister around, Jun and Azusa decide to sleepover at her house, in exchange for Azusa helping out with her underclassmen in the jazz club. After spending the night, they wake up to a rainy day. They go to an arcade where Ui hits a home run in a batting game, before Azusa is reminded that she needs to feed Ton. While in the music room, the three decide to have a jam session together. The other girls return the next day and give Azusa a keychain, one of a set that spells out 'light music club'.
