Crustaco, an adventurer and explorer, ventured into a dark underwater wave and discovered crystals imbued with the power of the sea. Due to the the mysterious power that resided in them, he knew their unique value and named them "Treasure Under Sea" (TUS). Promising to change the world for the better, he led a force that conquered the Seven Seas and united all Crabada factions under his rule to become the King of the Crabs. Shortly after, the first Crabada Kingdom was born. This Kingdom stretched across the seven seas, and her legion of Hermit-Crab warriors so mighty that the ground would tremble when they move.
