Mermaid melody is my childhood anime that's why I have it 7/10 as my final score. I don't know why I wrote a review this 2020 and this is my first review in MAL(oh my), I guess I have nothing to do but anyway I'll start my review now. Story is 5/10, its story has a lot of shoujo cliché moments, and everytime it has a battle, well you can predict what's next. So if you dislike those kinds of tropes then skip this one but watching this for enjoyment like a kid then it would be fun since I think this anime counts as achildhood anime.

Art is 6/10, it has the aesthetics of old anime art so just fair.

Sound and character is 7/10, well this is what made me stayed to watch, the character's singing. As I've said it became part of my life so the music and even bgm is good. Characters are also good even the bad ones, they have character development.

Overall and enjoyment 7/10, as long as I enjoy then it's Good
