Later in the storyline, it was revealed that Kaito is a prince of the Panthalassa race and is the younger twin brother of Gaito.
HistoryEditKaito was adopted by a pair of famous musician parents when he was found on the beach as a baby. He was considered the core of happiness in his parents life and was treated well. According to episode 38, he used to follow his Aunt Yuuri around a lot. Seven years ago, when he was on a cruise ship, he met a young mermaid when he heard her singing "Legend of the Mermaid". At that moment, a colossal tidal wave hit the ship, throwing him overboard and killing his parents on the ship.
Kaito was believed to be dead once the mermaid had saved him, so the mermaid gave him her pearl to save him. After regaining his consciousness, the two developed a relationship before the little mermaid departed. Seven years later, he is living on his own and surfs a lot. He kept a small pendant that holds the pearl around his neck.
Kaito is very easy going and flirtatious within the first few mintues of meeting, as shown in episode 1.

He is completely oblivious of the mermaid and Lucia being the same person, though he had visions and thoughts throughout the series.
