Nagi-Asu: A Lull in the Sea

Umimura residents Sakishima Hikari, Mukaido Manaka, Hiradaira Chisaki, and Isaki Kaname are transfered to Mihama Junior High on the surface.

Hikari gets annoyed that Manaka and Tsumugu are talking and tells him to not concern himself with the people of Umimura.

Akari and Hikari learn about the rule that if you are seeing someone from the surface, you will be banished from the village.

Hikari finds out that Akari's boyfriend is the father of the girl who had been fighting him, Miuna. Miuna asks him to help break them up.

Akari is able to tell Uroko-sama and her father how she feels about Itaru, and is starting to smile a little again.

The students get together for swimming class. The sea kids are getting used to school on land and are getting along with the other kids.

After school, the classmates gather for the final stretch finishing the Ojoshi-sama.

Akari decides 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.

Miuna makes a snow sea slug out of the saltflake snow that has fallen. Meanwhile, Hikari thinks about how his father is doing alone in the sea.

Uroko-sama tells that the Sea God's powers have become much smaller, and that the saltflake snow continues to fall both in the sea and on the surface.

Kaname suddenly confesses his feelings to Chisaki in front of her parents. Hikari and Manaka do their best to go on with the Ofunehiki.

Akari makes the decision to take Ojoshi-sama's place in the Ofunehiki and head into to marriage with Itaru like she was headed toward the Sea God.

After a brief talk with Tsumugu, Manaka returns home and meets Hikari. In the occasion, Hikari reaffirms his feelings for her.

Five years later, the sea over Shioshishio is frozen and the surface enters into a continued winter.

Chisaki learns of Hikari's return but refrains from meeting him. Hikari is still recovering from his hibernation when he meets his old friends.

Akari tells Hikari and Miuna that she was informed of Kaname waking from hibernation. They hurry over and find that Kaname hasn't aged at all.

By following Miuna's directions, the three finally arrive at Shioshishio. Hikari decides to return home and pay a visit to his father first.

After some examination, it is confirmed that although still asleep, Manaka is in good health and should wake up soon.

With no signs of Manaka awakening, Hikari keeps searching for Uroko with Kaname and Chisaki's help.
