Ruka is a young girl whose parents are separated and whose father works in an aquarium. When two boys, Umi and Sora, who were raised in the sea by dugongs, are brought to the aquarium, Ruka feels drawn to them and begins to realize that she has the same sort of supernatural connection to the ocean that they do. Umi and Sora's special power seems to be connected to strange events that have been occurring more and more frequently, such as the appearance of sea creatures far from their home territory and the disappearance of aquarium animals around the world.

User Reviews

beautiful but messy exercise in philosophy and animation
25 July 2020 | by ostialySee all my reviews

It starts surprisingly mundane. then mystery is added to drama, then romance. and it all goes ok, but then everything is abandoned for a mix of an early religion, cosmology etc. and that goes for a very long time and gets extremely boring.
