The upcoming Kin no Kuni Mizu no Kuni anime movie has released a teaser trailer, which introduces and previews the lead cast members for the film. The leads are Kento Kaku as Naranbayar and Minami Hamabe as Sarah.
The movie is set to premiere in Japan in Spring 2023. Kotono Watanabe (BTOOM!) is directing the movie with Fumi Tsubota (Waccha PriMagi! and Hugtto! Pretty Cure series composer) as scriptwriter. Mitsuki Masuhara (Ace of Diamond and Shirokuma Cafe director) is credited as animation supervisor, while Madhouse is the animation production company.
Kin no Kuni Mizu no Kuni is based on the Shogakukan-published manga by Nao Iwamoto, which ran from 2014 to 2016 in Monthly Flowers and has one tankoubon volume published under the Flower Comics label. The premise involves two constantly bickering neighboring countries that eventually go to war, causing God to intervene. Country A is told to offer its most beautiful girl as a bride, while Country B is told to send its wisest young man as a groom. In the midst of this, the princess of Country A has a chance meeting with a youth from Country B.
