Plot
For a long time, human civilization had lived on the ocean floor, developing a scale-like layer on their skins called Ena which allows them to live underwater. However, there were many humans who wanted to live above the surface and they moved to land creating a fundamental separation between the two. After Nami Junior High School closes down, four 14-year-old students from the sea village Shioshishio have to attend Mihama Junior High School on the surface. What follows is their struggles adjusting to a new environment and the relationships between the land and sea humans, while dealing with their own newfound feelings that have just started appearing with the end of their childhood.Characters
