The Skick Gosei Angels work vigorously with Eri planting seeds and singing a song to them to help them grow. By then, the Teckric Alien Mazuāta of Music arrives to play his ideal music to the people: pain-inducing rock music.

The others decide to fight without the Skick Gosei Angels are when the arcade machine comes to life, introducing himself as Datas from the Gosei World who Master Head has sent to help in Warstar detection. With the Skick Angels left behind, the Goseigers head to the concert were Mazuāta is as Buredoran personally fights them while Mazuāta continues to play rock music amplified across the planet to subject the people of Earth to his song.
However, Eri's singing voice is heard as Alata brings her to concert, negating Mazuāta's music as the broadcasting machine is destroyed. After Buredoran is driven off by the other Goseigers' Landsea Buster, the Skick Gosei Angels join them in using the Gosei Super Sonic attack before using the Gosei Buster to defeat Mazuāta.
