Summary:
Lucia Nanami, the mermaid princess of the North Pacific Ocean, sets out on land to find the boy that she had saved from a tsunami wave seven years before the beginning of the story, to whom she fell in love and had entrusted her pink pearl. She eventually finds the boy: a teenage surfer named Kaito Dōmoto. However, Kaito does not recognize Lucia in her human form. She cannot directly tell Kaito who she really is; otherwise, according to mermaid legend, she would turn into bubbles. At the same time, Lucia has been told that a group of water demons have invaded the sea world and she must gather six other Mermaid Princesses and their pearls to bring back the legendary goddess Aqua Regina to stop them. Would Lucia be able to save the seven seas? Or would her true form be revealed before her love?

Reaction:
I remember a few years ago, my friends told me about this anime but I never really got the time to watch it. Up until last year tho I finally watched it and I really liked it! I like the plot and the whole mermaid theme, and the characters are pretty cool. I got my other friend to watch this and she really liked it too! (She doesn't like anime that much either)

Favourite Character:
I think my favourite character is Seira. I won't talk too much about her (since it's sorta a spoiler) but she is a mermaid and she's cute. And I like her! Also her song, "Beautiful Wish" is one of my most favourite songs in the anime, probably my favourite

I also like one of the water demons, Yuuri. I dunno why, I just found her cute

Rating:
10/10! I really enjoyed it!
