Nagi no Asukara

Human civilization has long existed beneath the ocean, but a division formed when some people chose to live on land. Four 14-year-old students from the underwater village of Shioshishio must transfer to Mihama Middle School on the surface after their school shuts down. They face challenges adapting to life above water and navigating the complex dynamics between those from the sea and those from the land. At the same time, they begin to experience personal emotions as they transition out of childhood.
