Rametoto (ラメトト, Rametoto) is the National Chief of the Imuchakk Tribe, one of the countries that forms the Seven Seas Alliance. Rametoto is the owner of the Djinn Forneus. He is a Dungeon Capturer, capturing one Dungeon, and is a King Vessel. He abdicated on the throne and later joined to the the newly formed International Alliance, as Board of Directors.
Rametoto has a gigantic physique, like everyone of his race, with long hair and a long beard, tied in a braid. He has a scar that crosses his entire face, and his left eye has a different shape from the right. He carries around a Rampaging Unicorn horn as a weapon.
Rametoto seems to have the belief that if you can become stronger you have to.
In Sinbad no Bouken, Rametoto is quite threatening. He threatend Hinahoho after he replied with having nothing to offer to her daughter, who he claims has been given money, power, and social standing.
Despite being the leader of a confederation, he didn't believe in a unified world, and assumed it was impossible due to their vast differences.
Negative traits aside, Rametoto is a receptive man, being able to listen to reason before resorting to violence. He's able to respect those who are courageous, honest, and confident, mainly Sinbad and Hinahoho. While he initially didn't believe that a unified world is possible, he believes that Sinbad can accomplish his dream.
At some point in his life, Rametoto became a hero known throughout the world. He later conquered the 30th Dungeon and obtained his Djinn, Forneus.
He and the other kings perform their Full Djinn Equip, and he agrees with Darius Leoxses when he says that almost all of Sindria's Households are still in a "non-assimilation" state because Sinbad is an indulgent man. Rametoto repeats that Sinbad is indulgent and adds that warriors die if they don't fight and those who leave their harpoons rusting in front of their prey are just cowards. After the attack against the Medium begins, he performs his Extreme Magic along with all the Dungeon Capturers gathered in the battlefield.
Forneus is the Djinn that Rametoto obtained when he conquered the 30th Dungeon. Rametoto's Metal Vessel is a Rampaging Unicorn horn which he uses as a weapon, very similar to that of Hinahoho's. Only one member of his Household has been shown, a female monster with feral face.
