It's summer vacation, and at Mio's suggestion, the girls go to the beach for extreme training. After hearing the previous light music club's performance tape, she too wants to play at the school festival. Tsumugi invites them to her villa by the sea, saying that it is her dream to have them stay at her house. As soon as they get there, Yui and Ritsu begin to play on the beach, and soon both Mio and Tsumugi and playing along with them. Only when the sun sets does Mio realize that they need to practice and drags everyone inside. However, neither Yui nor Ritsu are in the mood for practice, and start fantasizing about having a maid cafe at the school festival. Later, Yui, standing in front of the fireworks, rocks out on her guitar. Mio, impressed, pulls out the tape of the previous club's live performance, to show what she is reaching for. Shockingly, Yui perfectly imitates the guitar part in the song, and Mio teaches her how to use vibrato. In the end, just before club practice begins, Mio writes on the board "Goal: Budokan! by the light music club"
