Sea of Death

Characters from the Sea of Death, created and ruled by Princess Mikotsu. They are the main opposing force of the Sea Kingdom and Wadanohara. Mikotsu attacks them in spite, as she is jealous that her sister, Princess Uomi, became princess of the Sea Kingdom and not herself. It can be assumed all characters that are a part of it are dead/undead.

VGPerson, in their English translation notes for the game, says that Sea of Death is a literal translation of the Japanese term for dead zones- shi no umi.
