How Gilthunder joined the Tourney
Back in the old days, Gilthunder was friends with Howzer, Veronica Liones, and Elizabeth Liones and used to play together. At some point of time, Meliodas taught Gilthunder the fundamentals of swordsmanship and "The Way of the Knight". Gilthunder used to look up to the Seven Deadly Sins and wanted to be just like them. During one point, Gilthunder became Margaret Liones personal knight and grew a crush on her during their childhood. During one of his training with Meliodas, Gilthunder grew upset as he believe he will never become as strong as the Deadly Sins or his father, but Meliodas told him to ditch his negative attitude and Margaret came, and told him the The Way of the Knight creed. Margaret told Gilthunder that he should be himself, and not like the Deadly Sins or his father, and she believes that Gilthunder will be the kindest and strongest Holy Knight some day which cheers up Gilthunder. However, the next day Gilthunder came running toward Meliodas and told him to run away with the others. Meliodas was lost at Gilthunder and told him to explain everything, but Gilthunder told him something terrible is coming and if he told somebody, bad things will happen, and Gilthunder has no idea what to do.
Meliodas told Gilthunder to calm down by hitting his head and told him what he want to do, which Gilthunder said that he need to protect Margaret, but has no idea how to do it. Meliodas teach him a charm which could cheer him up whenever he feels sad or terrible which was to say out loud that he was stronger than any of the Seven Deadly Sins. Gilthunder said it, which Meliodas points out that he should feel better soon. Meliodas embrace Gilthunder, told him he shouldn't cry, and if he is in trouble, he will come to his aid. Ten years later, Gilthunder was now force to join with the Holy Knights for Margaret's safety and somehow knew of his father true murderer.
Searching for his father's true killer, Gilthunder searches Lylat for possible suspects. On the Great Fox, he suspects, Slippy Toad.
