Just before the arrival of a certain transfer student, three students at an academy in Paldea are tasked with making a video showcasing their school. The reserved Ohara is a skilled flutist, but she’s feeling under pressure due to an upcoming concert. In addition, she’s doing her best to help with the video, but it just isn’t going right. Fed up with it all, she runs away to Glaseado Mountain, under the pretext of doing the academy’s Treasure Hunt activity.

After consulting his older brother, Aliquis is advised to stop using a Pokémon after it loses a match. What will he do? Can Aliquis and Meowscarada find the strength within themselves to take on Nemona?
