Thief Gaston (シーフガストン, Meijūjin Shīfu Gasuton, 25) stole Kai's courage and the ticket Hikaru uses to summon Travelion. He was then ordered to use some of the other items he had stolen to make the "Important Item Dynamite" which was supposed to blow up the surface world by causing the cherished items of the humans to explode once it was detonated. Kai soon rejoined his siblings as he regained his courage to form MagiKing, while Hikaru regained control of Travelion from Nai & Mea, killing Gaston with it.
