Adaptation of the manga by Daisuke Igarashi, the film is directed by Ayumu Watanabe, with the character design and animation direction by Kenichi Konishi and the soundtrack composed by Joe Hisaishi.

The story talks about the two faces of the sea. What appears on the surface and the secret one, hidden in the depths. Evocative, surreal, disturbing and extraordinary will be the adventure of a girl discovering a great mystery enclosed in the oceanic depths.

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.

However, the exact nature of the boys’ power and of the abnormal events is unknown, and Ruka gets drawn into investigating the mystery that surrounds her new friends.

Children of the Sea will release in Hong Kong on 25 July 2019.
