Tập 20: Sống hay Chết?! Chiến trường của D

20

In a post-apocalyptic wasteland, Happy Around! is bragging about controlling the world's music when they are attacked by Peaky P-key and their robots. The two units' fight is interrupted by Rondo, who wishes to seize the music for themselves, but are in turn ambushed by Merm4id shooting water at them. Merm4id's own attack is halted when Photon Maiden appears with psychic powers and repeatedly slams the other units into the ground. Lyrical Lily, with powers of motherhood, stops the battle by turning everyone into babies. (Source: Wikipedia)
