A secret Guild where all the members are demigods or children of Dragons, thus they are semi-immortal. Their stated goal is to replace their parents and become the new gods of the World of Twelve, believing that the gods don't care about them and that the world has become horribly corrupt under their rule. They threw down the gauntlet against the Brotherhood of Tofu in Season 3 because their leader, Oropo, desires both the Percedal family children and Ruel to join their new pantheon. Furthermore, he has an unspecified need for Yugo's help as well in his plan. To that end, he is using the weaknesses and doubts in the characters to try to bring them to his side. However, later episodes reveal that not everyone in The Siblings fully trusts their leader and some begin to move on their own. Netflix acquired the right to the show and started showing it on its streaming, according to "Variety" Ted Sarandos, Netflix's CCO, said "Animation has a very strong history in France and French animators are among the best and most innovative in the world." Sarandos added that Netflix expected "to further strengthen our relationship with Ankama and other French animation studios." The series started airing on Netflix in September 2014. The dub for Season 3 uses an entirely new voice cast based in Los Angeles. On January 20, 2014, Ankama launched a Kickstarter campaign to produce an English-language dub of the series for release on region-free Blu-ray Disc in English speaking territories. The campaign had a target of $80,000 Canadian Dollars to dub the first season, with stretch goals to produce dubs of the second season and various original video animation episodes. The campaign's goal to dub Season 1 was met on January 21, 2014, and the campaign's goal to dub Season 2 was met on January 30, 2014. On June 8, 2020, Ankama launched yet another Kickstarter campaign for the production of the fourth and final season of the series, with an initial target of €100,000; the target was reached within an hour after the campaign was started.
