His sister Shetra and his best friend Raina died trying to help Adlet escape the village when the rest of the villagers were brainwashed. When Adlet was ten, a cunning Kyouma named Tgurneu appeared in his village, Hasuna. Because of what happened in his village, he harbors a strong hatred for Tgurneu. He usually tries to talk things out rather than fight himself as well, and among the heroes, is the character who trusts the others the most easily. With Mora, he's one of the two heroes who usually try to calm down others when they start fighting. Because of those methods, he's looked down by others who call his ways of fighting dirty and despicable. He's also well aware that for an ordinary person, becoming the strongest man on earth can only be done with this kind of methods.
He takes pride in his method of fighting, saying that the strongest man on earth is someone who uses everything to bring down his opponent and win. He defines himself as an "ordinary person", opposed to the other heroes who are either genius fighters or Saints. He has an abnormally strong will, never giving up even in the dire situations, as well as a strong sense of camaraderie and friendship. Self-proclaimed "strongest man on earth", he has the verbal tic of using those words in almost every sentence, a verbal tic that people often poke fun at, calling him an idiot. 3.3.3 Reuniting with Nashetania and Goldof.
