Umi Osho

A monster with a large turtle shell on its back that inhabits the seas of Zipangu. Having meek and timid personalities; not only do they not attack humans, it is said that sometimes they are so astonished when they come across a human that they hide in their shells, refusing to come out. Like "Sea Bishops", they are the priestesses who serve the sea god, and they can perform the ritual to remake the bodies of human men who are joined with monsters in the sea, enabling them to live in the sea. Due to this ability and their honest and simple nature, they are loved by monsters of the sea.
