Nikora
Nikora is originally a mermaid from Lucia's kingdom, though she resides on land. She is the manager of the Pink Piarre Hotel. Lucia comes to stay at her hotel when she first comes up on the human land.Lucia is like a younger sister to Nikora (and Nikora even asks Lucia to address her "big sister"). Like Hippo, Nikaro will occasionally scold Lucia and remind her of her duties as a mermaid princess. In some cases, she will have Lucia help her with various chores around the hotel. Regardless, she loves Lucia, and the two share a sisterly bond with each other.
