As Criticrista prepare for the battle of the bands, Dagger converses with his songwriter. Meanwhile, Chuchu suggests that the girls learn how to improve their performance to enhance their appeal to the fans. When Rom passes this off as superficial, Retoree shows Chuchu a photo of their training camp, showing her the most important thing is to have fun. On the day of the battle, Cyan grows concerned by the attention she gets from Criticrista's lead, Rosia, which also stirs up some dark feelings in Chuchu, but Plasmagica manage to bring out their smiles in their performance and win the battle. However, Dagger punishes Criticrista for their loss by darkening their Melodisian Stones.
