In ancient times, all of mankind lived underwater. As time passes, those who longed for the land moved ashore by casting away special layer that was once gifted to them from the Sea God. Both the people under the sea and the people on the surface have differences, but they are both same humans, so there are still interactions between the two.
Hikari Sakishima, Manaka Mukaido, Chisaki Hiradaira, and Kaname Isaki are children who live in the underwater village, and Tsumugu Kihara is a boy who lives on the surface.
Of the sea and land, these children are all the same age but grew up in two different environments. When they who have never met before, meet, their emotions fluctuate like the water in the ocean.
A storytelling fantasy of boys and girls that takes place in a fantastical world.
