Karen's Castle and her servants

The Antarctic Ocean Castle is the home of the Mermaid Princess, Karen, and her servants. The castle only appeared once, in episode 27 during a flashback.


Karen's Kingdom is at the South Pole. After defeating Gaito, Karen returns to her kingdom to rebuild it along with the mermaids.
