Sea Monks (海坊主 Umibōzu) are Demons that can manipulate coral and reef organisms. They are associated with Egyn.


A relative of the Greenman, Sea Monks can control the growth of sea organisms in much the same way.[1] They seem to be able to live for a considerable period, becoming one of the oldest creatures in a particular stretch of sea.[2]
