Children of the Sea (film)

After a falling out with both her mother and the other members of her school club, female lead and junior high school student Ruka finds herself with nowhere to spend her days during summer vacation, and so she ends up hanging out at the aquarium where her father works. While there, she meets a mysterious pair of brothers, named Umi ("sea") and Sora ("sky"), who her father tells her were "raised by dugongs," and are being observed for their aquatic abilities.{{Cite news|last=Phillips|first=Maya|date=2020-09-02|title='Children of the Sea' Review: Finding Beauty in the Watery Depths|language=en-US|work=The New York Times|url=https://www.nytimes.com/2020/09/02/movies/children-of-the-sea-review.html|access-date=2020-09-03|issn=0362-4331|archive-date=2020-09-03|archive-url=https://web.archive.org/web/20200903004155/https://www.nytimes.com/2020/09/02/movies/children-of-the-sea-review.html|url-status=live}} The three teens share some sort of connection to a series of supernatural phenomena that have been affecting the world's marine life, such as a comet falling into the sea and aquatic life from around the world gathering in Japan.{{Cite web |first=Casey |last=Baseel |url=https://soranews24.com/2019/05/28/anime-film-children-of-the-seas-trailer-is-heartbreakingly-beautiful-looks-like-nothing-else |title=Anime film "Children of the Sea"'s trailer is heartbreakingly beautiful, looks like nothing else |date=May 28, 2019 |website=SoraNews24 |access-date=May 28, 2019 |publisher=Socio Corporation |archive-date=May 28, 2019 |archive-url=https://web.archive.org/web/20190528170249/https://soranews24.com/2019/05/28/anime-film-children-of-the-seas-trailer-is-heartbreakingly-beautiful-looks-like-nothing-else/ |url-status=live }}

The original musical score of the film is composed by Joe Hisaishi, a long-time collaborator of Studio Ghibli. When talking about the film, Hisaishi says "What's interesting about this movie is that it has things you wouldn't expect as story… I stuck to a minimalist music style for the entire picture, so it has been quite a challenge as a film score. The film inspires the viewer's imagination of the universe's memories and the effervescence of life."

This film, together with Ni no Kuni, released two months later, mark Hisaishi's first two scores for animated feature films since 2013's The Tale of the Princess Kaguya, directed by Isao Takahata,{{Cite web|url=https://www.otakuusamagazine.com/children-sea-anime-film-looks-sounds-incredible-new-trailer/|title=Children of the Sea Anime Film Looks and Sounds Incredible in New Trailer|date=2019-04-09|website=Otaku USA Magazine|language=en-US|access-date=2019-05-29|archive-date=2019-05-29|archive-url=https://web.archive.org/web/20190529152404/https://www.otakuusamagazine.com/children-sea-anime-film-looks-sounds-incredible-new-trailer/|url-status=dead}} and the first non-interactive animated productions not produced by Studio Ghibli with music by Hisaishi since the release of Venus Wars in 1989.{{cite web |title=Hisaishi Jō no purofīru – allcinema |script-title=ja:久石譲(Joe Hisaishi) のプロフィール – allcinema |trans-title=Profile of Joe Hisaishi – allcinema |url=http://www.allcinema.net/prog/show_p.php?num_p=118212 |publisher=Stingray |access-date=May 29, 2019 |language=ja |date=2019 |archive-date=September 23, 2018 |archive-url=https://web.archive.org/web/20180923125325/http://www.allcinema.net/prog/show_p.php?num_p=118212 |url-status=live }}
