An aluring sly mermaid with a double personality
She has two different personalities, which is what makes her so unpredictable.
April: Her first personality. She's the type of mermaid that isn't afraid to sing until the sailor jump to their waterygrave or until she hypnotizes them. She likes to play tricks on people and has a rather cruel personality.
May: Her second personality. She's as sweet as candy, the nicest mermaid you'll ever met. She is hestiant to hurt or trick anyone and tends to be quite helpful, even to those that don't deserve it.
April May tends to be the most mentally unstable mermaid. No one really knows why she devloped a second personality or why she has such a sweet side to her.
