The leader of the Maruhage Empire. His name is an onomatopoeia for something slippery. Growing up, he was apparently wealthy, and at some point, he became the fourth leader of the Maruhage Empire.
SpoilerDuring his childhood, he was extremely cruel to his younger brother Hydrate, to the point where one day, Tsurulina IV had him thrown into the dark realm (an action that he would regret years from now).
