Umisachihiko (“Luck of the Sea”), called Umi for short, is an oceanic world. The world’s dotted islands are flooded for half the day during High Tide, so colonies must be built on stilts or float.
From the surface of Umi, the ever-present Orochi Nebula resembles a green, black and red striped serpent with eight heads and eight tails. Over the course of a single day, the entire nebula can be seen as prominently as the Milky Way.
The Hitohirowani, also called the Wani for short, is a crocodile-fish native to Umi which ranges from 6 ft. to 35 ft. in length.
The Namazu is a native animal which resembles a giant catfish.
The Shojo are native sea-monkey-like creatures.
