20,000 years prior, the castle was sealed away by Saint Beast Lakia, who remained on Earth and use his own power in conjunction with the seals of the fairies to keep the Boma at bay. However due to the weakening of the seals by human pollution and lack of belief in fairies, all Boma seals became weakened to the point that their members began to remove them and revive. When several of the Boma elite returned, Lakia tried to prevent them from removing his own seal, but his own weakened state and the strength of the returning Boma were enough to stop him and remove the final seal of the castle, allowing for it and the Boma Leader, Great Boma Emperor Lagorn, to become released into modern times.Ep. 2: Did You Guys See a Fairy!?Ep. 3: Boma Castle!
