As PowaPowa Puririn prepare for the Great Starlight School Festival, Shion learns that the recording schedule for the movie she is starring conflicts with their concert, but becomes determined to attend both. Hearing how hard Shion is working, Hinaki decides to show her support and goes to the mountains, where Shion is training for her role as a ninja. On the day of the festival's first round, Otome and Sakura place their faith in Shion and wait for her to arrive, allowing them to perform as a trio as planned. During their performance, they are joined by Seira and the other Dream Academy idols, who give a video performance.
