Set in a modern-day kingdom, Alexa is a shy, book-reading princess who avoids doing the duties expected of her due to her rank.

Alexa meets Nori, a fairy missing her wings, and Romy, a mermaid with legs instead of her tail.

Alexa, Nori, and Romy travel to the Queen Unicorn, hoping to protect her, only to unintentionally lead Malucia and her minions right to her.

Malucia captures the Queen Unicorn, while Nori and Romy provide a distraction so that Alexa can escape.

After promising to visit again soon, Alexa returns to her kingdom more confident, and more willing to participate in her princess duties.
