Synthesized from 9 Yomimono stories · updated 3h ago

The anime of Nao Iwamoto's The Seven Knights of the Marronnier Kingdom has been on NHK Educational since October 3, with Amazon Prime Video streaming the series and an English dub. The production was set well before launch: Kiyoko Sayama directs at J.C. Staff, and the seven brothers are voiced by Kengo Takanashi, Makoto Tanikawa, Haruki Ishiya, Satoshi Inomata, Kiyoto Mizuno, Taishi Murata, and Reiji Kawashima. A second trailer in September confirmed five more cast members and the opening song "Sayonara wa Iwanai" by yama.

Since the premiere, the announcements have been cast additions tied to individual episodes. Shoya Ishige was cast as Johann, a noble house's son from Marronnier's western territory and vice captain of the Marronnier knights, ahead of the third episode. Four royal family roles for the Country of Long Nights arc, which starts in episode 4, went to Naomi Shindo, Atsushi Ono, Ai Kayano, and Yurie Funato. Ryota Takeuchi was added as Saturno for the sixth episode, and Yusuke Kobayashi as a mysterious boy with a plan for the seven brothers in the seventh.

The premise is seven brother knights sent as goodwill ambassadors to neighboring kingdoms, each bound for a land matching his name. The premiere introduced Lady General Baribara, who commands the knights, and Princess Brunhild, who disguises herself as the margrave Lord Bruno. Viz Media licensed the manga on October 1 and put the first two chapters out digitally the same day. The manga launched in Shogakukan's Flowers magazine in 2016, and Shogakukan shipped the 11th compiled volume on June 10.
