About
Long ago, all humans lived beneath the sea. However, some people preferred the surface and abandoned living underwater permanently. As a consequence, they were stripped of their god-given protection called "Ena" which allowed them to breathe underwater. Over time, the rift between the denizens of the sea and of the surface widened, although contact between the two peoples still existed. This show follows the story of Hikari Sakishima and Manaka Mukaido, along with their childhood friends Chisaki Hiradaira and Kaname Isaki, who are forced to leave the sea and attend a school on the surface. There, the group also meets Tsumugu Kihara, a fellow student and fisherman who loves the sea. Hikari and his friends' lives are bound to change as they have to deal with the deep-seated hatred and discrimination between the people of sea and of the surface, the storms in their personal lives, as well as an impending tempest which may spell doom for all who dwell on the surface.

Season 1
In Between the Sea and the Land
Because of their Hamaji Junior High School closing, Umimura residents Sakishima Hikari, Mukaido Manaka, Hiradaira Chisaki, and Isaki Kaname are transfered to Mihama Junior High on the surface.
The Chilly Desert
Because of Uroko-sama's curse, Manaka ends up with a fish face on her knee. It goes away the next day, but she has some regrets because Tsumugu had said it was pretty. Meanwhile, Hikari gets annoyed that Manaka and Tsumugu are talking and tells him to not concern himself with the people of Umimura.
The Legend of the Sea
Akari was rounded up by the older men of the village and Hikari and the others try to stop them. It's there that they first hear the rule that if you are seeing someone from the surface, you will be banished from the village. Hikari, unable to contain his rage, holds a guys-only meeting with Kaname. The girls are thrown out and go to another room, where Manaka finds a red-bellied sea slug. The sea slug is said to tell you the future if you tell it feelings you can't tell anyone else. It's then that Chisaki asks Manaka if she likes Tsumugu-kun...
Because We're Friends
Hikari finds out that Akari's boyfriend is in fact the father of the girl who had been picking fights with him, Miuna. Miuna asks him to help break the two apart. The next day, they are cooking in class and the Umimura kids are being isolated. Manaka works up the courage and tries to get the surface kids to try the food they made, but is greeted with an unfriendly response. Seeing that, Hikari jumps in...
Hey, Sea Slug
Akari is able to tell Uroko-sama and her father how she feels about Itaru, and is starting to smile a little again. Hikari sees that and feels a little better and heads to school. While on their way to school, Chisaki is late and walking on her own.
Beyond Tomoebi
The students get together in their swimsuits for swimming class. The sea kids are still getting used to school on land, but are starting to get along with the other kids. The teacher mentions that he's going to be timing them today and as the kids groan in response, Hikari and Tsumugu's rivalry fires up.
The Ofunehiki Shakes
After school, the classmates get together in the woodshop room for the final stretch of getting the Ojoshi-sama done. After the students finish the Ojoshi-sama, even the teacher gets excited about the feat, and they wonder if it's possible to somehow do an actual Ofunehiki like they used to do with the surface and the sea working together.
Beyond the Wavering Feelings
Akari decides once and for all that she is going to live on the surface, and Hikari also leaves the house because he feels that Akari isn't being treated fairly.
