The Deep Sea King (深海王, Shinkaiō) ruled over the Seafolk as their king, and claimed the deep sea as his own. The Deep Sea King is a rather sadistic individual, who enjoys causing pain to others and starting fights. He is determined to take the surface world for himself to rule. He regards people as little more than food and has no qualms about treating them as such. He is also very arrogant and prideful, considering himself to be better than everyone and stating that he stands at the very top of the pyramid of all living organisms on the planet.
