Kaito Doumoto is one of the main characters of the Mermaid Melody: Pichi Pichi Pitch anime and manga.
Kaito, Lucia's love interest, is a smug local celebrity due to his incredible surfing ability and a gaggle of fangirls that follows him everywhere. He pays little attention to them, but nobody knows that it's because his heart really belongs to a certain mermaid that saved his life as a child when his parents were killed in a storm. When he sees her again years later, he returns her pearl and begins to search for her, but all the while, he learns that this ditzy girl in his class named Lucia is different from his regular fan club. As Kaito becomes more and more confused, he develops powers that no human should display, making him an easy and interesting target for Lucia's enemies.
In the AWA fics, Kaito is a student at the AWA Academy.
His hair is orange-brown a little red and spiky and he has brown eyes. As pointed out, he resembles his brother Gaito. He wears a variety of different clothes on land such as a white jacket and black turtle neck or a red jacket and a white shirt. While surfing he wears a red, black, and slightly yellow wet suit. In water he wears a blue, red, and yellow outfit with a whiteish cape. His school uniform looks like any other male uniform of his school with a white button down shirt and blue pants.
Kaito is very interested in surfing since he was still a child, and is a very easygoing person. He is shown to be popular with girls and can be quite flirtatious, even perverted to an extent, as he comments on Lucia's outfit that her clothes are cute, but he prefers "more racey outfits."
He is completely oblivious to the fact that Lucia is the mermaid that saved him as a child. Despite this, he had several times where he questioned if Lucia could be that mermaid and compared her human and mermaid forms throughout the series.
- Kaito is a talented surfer.
