The Children of the Sea manga from Daisuke Igarashi was revealed last summer to be making the leap to anime with a theatrical film with a planned June 7th, 2019 debut in Japanese. With some cast additions and changes the last time around, the latest update on the project that’s just under a month away are a pair of new promos with a 30-second version and a 60-second version. Ayumu Watanabe is directing and character designs are by Kenichi Konishi. Studio 4°C is on board to handle the production for it.
GKIDS revealed earlier this year that they’ll be handling North American distribution for it with plans for a theatrical release later this year with both Japanese and English showings planned for it.
The Japanese cast includes Hiiro Ishibashi as Umi, Mana Ashida as Ruka, Seishu Uragami as Sora, Sumiko Fuji as Dede, Goro Inagaki as Masaaki Azumi, Yuu Aoi as Kanako Azumi, Toru Watanabe, Min Tanaka as Jim, and Win Morisaki as Anglade
Plot Concept: When Ruka was younger, she saw a ghost in the water at the aquarium where her dad works. Now she feels drawn toward the aquarium and the two mysterious boys she meets there, Umi and Sora. They were raised by dugongs and hear the same strange calls from the sea as she does. Ruka’s dad and the other adults who work at the aquarium are only distantly aware of what the children are experiencing as they get caught up in the mystery of the worldwide disappearance of the oceans’ fish.
