The main cast, confirmed by multiple outlets, stars Yōko Hikasa as Empress Navier, Ryōhei Kimura as Heinrey, Tomoaki Maeno as Emperor Sovieshu, and Reina Ueda as Rashta. The staff, as detailed by Anime Trending and Anime News Network, includes Tetsuya Yanagisawa (*Berserk of Gluttony*, *High School DxD*) directing, Akiko Inoue (*An Observation Log of My Fiancée Who Calls Herself a Villainess*) supervising and writing the series scripts, Jun Nakai (*GATE*, *NieR:Automata Ver1.1a*) on character design, and Yūki Fukazawa composing the music. The story follows Navier, the perfect Empress of the Eastern Empire, who chooses divorce when her husband plans to replace her with his mistress — and resolves to become an Empress in another land.

Anime Trending traces the franchise's origins to a web novel Alphatart serialized from November 2018 to March 2020, followed by the Sumpul-drawn webtoon that launched on Naver Webtoon in October 2019 — a run that ended this January after seven years, though ANN reports it will return this fall with side stories. Eleven physical volumes exist as of August 2026, per Anime Trending.

The announcement is only the flagship of something larger. Inven Global reports that LINE Digital Frontier, the Japanese affiliate of NAVER WEBTOON, has entered a partnership with anime production company HAYATE and Crunchyroll to co-produce webtoon-based anime, cooperating from the planning stage with the goal of adapting around 15 titles; HAYATE was jointly established by Aniplex and Crunchyroll in 2025. Se7en.ws identifies the first three titles as *The Remarried Empress*, *Teenage Mercenary*, and *The Boxer*, with Crunchyroll streaming the results exclusively in select territories. Solo Leveling's success proved these properties can travel, which is why Sony's ecosystem is stepping in directly.
