Kasumi the Magical Mermaid

An anime movie based on the Hans Christian Andersen fairy tale of the same name. And we all know how it goes so no need to explain the story.

Plot
The main character Kasumi looks a lot like Kasumi (Misty) from Pokemon in her mermaid outfit she wore in the episode "The Misty Mermaid" (Hanada Gym! Underwater Battle!). The only difference is that she doesn't have the star on her tail as well as the her necklaces, earrings and others. And it doesn't feature sea Pokemon and instead real sea creatures.
