The Sea God is the creator of the sea who gave his children ena to help them live in the sea.
The Sea God has the exact same features as Uroko. Tiny, sharp red eyebrows, long scruffy silver hair, and has scales on his body.
The Sea God fell in love with the sacrifice given to him by the humans that lived on the land. Unfortunately, Ojoshi-sama still loved a man that was still living on the surface not knowing that the man had drowned in the sea looking for her. To prevent her from being sad, the Sea God removed Ojoshi-sama's emotions of love so she won't suffer the death of her loved one. Ironically, the Sea God also removed the love directed towards him by Ojoshi-sama.
