The story

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.

What it’s like

Sun-dappled and watercolor-soft, with bright summer blues, sea glinting off shallow water, and the pale green of coastal hills, all rendered in gentle hand-drawn animation. Long, unhurried shots linger on tide pools, ferry decks, and classroom windows, and the score is airy piano and strings that drift in and out, with the sound of waves and wind doing much of the work. The vibe is warm nostalgia with a thread of unease running underneath, a sunny summer that could turn. Its pacing is leisurely and episodic, built around everyday moments: swimming, shared meals, bike rides along the coast, quiet talks at the water's edge. Emotionally it moves through friendship, first crushes, and the slow strain of old loyalties meeting new prejudice, following a group of teenagers who each carry their own private storms. The intensity is low to moderate: there is bullying and social hostility, some tense confrontations, and a looming disaster in the later episodes, but violence is rare, brief, and never graphic. It suits a rainy-afternoon watch, a gentle comfort rewatch, or a long evening when you want something tender with a little ache. It is for viewers who love coming-of-age stories, sea-set worlds, and slow, emotionally honest drama with a soft, luminous look.
