The Seven Knights of the Marronnier Kingdom anime is airing on NHK Educational after premiering October 3, with new cast additions announced through mid-October, including Shoya Ishige as Johann in the third episode. Amazon Prime Video streams the series, and Viz Media is publishing the manga in English.
The Seven Knights of the Marronnier Kingdom arrived in English in two coordinated pieces. Viz Media announced the manga license and posted the first two chapters digitally the same day. The same week, the anime premiered on NHK Educational on October 3 at 6:25 p.m. JST. Amazon Prime Video began streaming the next day.
The production had been outlined in stages. A first promotional video in early August confirmed Kiyoko Sayama directing at J.C. Staff and the seven voice actors for the knight brothers, alongside the October 3 premiere date. A second trailer in September added five cast members and the opening song, "Sayonara wa Iwanai," performed by yama. The most recent cast news named Shoya Ishige as Johann, a western-territory noble and vice captain of the Marronnier knights, ahead of his appearance in the third episode.
The premiere itself set the premise in motion: seven brother knights serve as goodwill ambassadors to neighboring kingdoms, each bound for a land matching his name. Lady General Baribara commands them, and Princess Brunhild disguises herself as the margrave Lord Bruno. Across the stories, one structural fact recurs: seven brothers, eight kingdoms, and a quest built to send each knight toward a fated partner.
