A Lull in the Sea Review — the 2013 heartbreaker that still holds up
Revisited in 2026, this 26-episode undersea coming-of-age story remains one of the decade's most quietly devastating ensemble romances.
By Theo Grange · AnimeSphere staff · July 17, 2026
A patient, painterly ensemble drama whose emotional gut-punches have aged beautifully — the slow start is the toll.

Here is my thesis after a fresh binge: A Lull in the Sea is one of the few mid-2010s dramas that plays better today than it did in 2013. Back then, a 26-episode original fantasy about children from an undersea village attending school on the surface felt like an indulgence in an era already pivoting to tight one-cour seasons. Watched now, that length is the whole point. The show has room to let grudges rot, crushes curdle into jealousy, and an entire tangled web of adolescent longing tighten one knot at a time.
The premise — sea-dwellers and land-dwellers sharing classrooms while their communities quietly resent each other — sounds like allegory homework, but the fantasy scaffolding mostly stays out of the way of what the show actually cares about: five kids discovering that loving someone and being ready for them are different things. Compared to its contemporaries, which tended to sprint to a confession by episode ten, this one understands that unrequited feeling is a long-term condition.
Does it hold up on a modern binge? Largely, yes — with one honest caveat: the first stretch leans hard on repetitive misunderstanding plots, and a 2026 viewer trained on faster shows will feel those early episodes drag. Push through. The community's 77 average undersells how hard the back half hits, and all 26 episodes are free on AnimeSphere right now. Bring something to wring out.
