Five mermaid girls arguing over snack cakes in a quiet village, then suddenly on stages under spotlights, this show knows the gap between who you are and who you're performing to be the entire point. The early animation stumbles, but once it stabilizes around episode four, the character designs carry real warmth without trying to be anything other than simple and pleasant. It's CGDCT that remembers the girls come first, the idol framing second.

Five young mermaid girls live in the quiet underwater village of Parrel, long before any thought of idol stardom on a big city stage. For now, they are content with simpler pleasures, like squabbling over the snack cakes they share and exploring their town and the waters around it. Being a mermaid comes with charm and mysterious powers, but daily life still brings ordinary troubles, and the girls lean on one another to get through each one. The show is a lighthearted comedy with fantasy and slice of life elements, built around cheerful everyday moments and the support of friends. It spins off from the Bermuda Triangle clan of Bushiroad's Cardfight!! Vanguard trading card game.
