The alien ship wants Yuuma's help to get back to space!

Kousuke and Natsume have been friends since childhood, but as time goes on, the relationship between the two sixth graders seems strained as they keep avoiding each other. One day during the summer vacation, they visit a housing complex that is scheduled to be demolished. Having grown up there, the place holds a lot of memories, but while playing, they suddenly get caught up in a mysterious phenomenon. When they regain consciousness, they see an entire ocean before them as the housing complex has drifted into a mysterious sea with Kousuke, Natsume, and others in it. Will they be able to return to their previous world? A summer farewell journey begins...

Despite Kyouko Honda's tragic death, her vivid memory lives on, providing guidance through times of hardship to her close ones. However, Kyouko was not always the wise and radiant person that she is fondly remembered as in the present day. Feeling deserted by her own family and rejected by society, a young Kyouko abandons stability for a life of delinquency, jeopardizing her education and future. Fortunately, her descent into despair is interrupted by a fateful encounter with her husband-to-be Katsuya, who has recently started his teaching internship at her school. With a composure surprisingly unaffected by Kyouko's tantrums, Katsuya quickly wins her over through his gentleness and attention toward her—sincere gestures that she has never received before. As the two grow closer together, Kyouko opens her tormented heart to him and, along with it, a door to new horizons.
