When the ocean dominates the earth, there are eight administrators in charge of the sea, The Sea Gods. My idea is to combine sea creatures with figures in feudal Japanese style. There are three groups of my characters: The Ministry of Abyss, the Ministry of Tide, and the Ministry of Storm.
Here is the Ministry of Abyss is in charge of the seabed. They are trickster, giant, and prophet who well know of mystery skills and magic.
