The Seven Knights of the Marronnier Kingdom topping Kono Manga ga Sugoi! 2018 shows real critical pedigree because winning the best manga for female readers spot signals strong storytelling that should translate well to screen. Kiyoko Sayama directing also brings emotional depth experience since her work as chief director on To Your Eternity showed she can handle character-driven journeys with real heart, which fits this fantasy romance perfectly. J.C.STAFF on a josei fantasy is an interesting fit too because the studio has wide range across genres, and a romantic adventure following seven brothers gives them plenty of distinct characters to develop. And Yoshiaki Fujisawa on music is a fantastic pickup because his sweeping score for Mushoku Tensei proved he can craft grand fantasy soundscapes, which should elevate the medieval-style adventure setting.

Japanese broadcaster NHK revealed today that an anime adaptation of Nao Iwamoto's Marronnier Okoku no Shichinin no Kishi (The Seven Knights of the Marronnier Kingdom) manga is in production for a planned October 2026 release. A teaser visual and animation staff details were also shared.
