Gaito (楽斗/ガクト Gakuto) is the leader of the sea monsters (Dark Lovers) who is bent on taking over the marine world, but is secretly ruled by Sara. He is also the older twin brother of Kaito. He is also member of Panthalassa Tribe, granting him various powers.
His two main goals were to find his twin brother, Kaito, and to capture all seven of the Mermaid Princessess. He needed Kaito because he thought that once the two were together, their powers combined were strong enough to take over the world, not knowing that it was strong enough to destroy the world instead. He needed all seven Mermaid Princesses to revive Aqua Regina, who he thought he could use to assist him in taking over the world. In the manga, he is referred to as "Gackto".
Like Kaito, Gaito is part of the Panthalassa race and was one of the descendents who was given a cursed fate, Gaito possessing the power of darkness. Because Aqua Regina lacked the power to break the curse, she had to separate them, causing Gaito to become very lonely. He lived at the very bottom of the sea and was only accompanied by his sea creatures, whom later became the Dark Lovers with his dark powers. He later came across Sara, whom he believe was going through the same sort of loneliness that he was going through, causing him to fall in love with her.
On the first season, Gaito was the main antagonist. He is always seen in his castle. He is in love with Sara, and as he said in the last episode of Mermaid Melody Pichi Pichi Pitch, Sara shared the same loneliness with him. His destruction of the human world was Sara's request. He was delighted when Sara decided to go with him in the end. And he died at the end of the first season. When he lost his power he stayed with his castle and Sara came back with him.
In the second season of Episode 14 as a spirit appears before Kaito, reminding him who is his most important person.
His main goal in the entire first season is to collect all of the seven countries princesses to call forth Aqua Regina. He then will use her power to control all the oceans. From the very first episode his minions already captured the South Pacific Ocean Princess Coco and the Arctic Ocean Princess, Noel. And also having the not princess any more, Sara.
Gaito can be rather impatient when his servants constanly fail him,but he always has a soft side whenever he is with Sara. and can become jealous when it seems like Sara is thinking of someone else other than him and will do whatever it takes to win her heart back.However,when he is betrayed,he can become even more cruel and sadistic.
Gaito has spikey grey hair and pink eyes. He wears lightning earrings with a loose attached black robe. And also, black pants and pointy shoes. He has a dark red necklace and is usually seen holding a rose, wine, or his staff.
