本物のルミ vs 偽のルミ! マーメイドエクストリームメイクオーバー KPOPデーモンハンターのルミに変身

Obsessed with K-pop dancing, a Mermaid goes ashore and puts Rumi to sleep, disguising herself as Rumi to sneak into the Huntrix academy alongside Zoey and Mira. When the real Rumi wakes up and rushes to class, the Mermaid's cover is blown, and she is sadly kicked out. Just as she is leaving, the Demon King suddenly appears to steal the Huntrix group's music. Ignoring her recent rejection, the Mermaid bravely uses her magical powers to team up with the girls and defeat the villain. Grateful for her heroism, the Huntrix members gladly welcome the Mermaid to study K-pop with them.
