A first promotional video has been released for The Villainess Is Adored by the Prince of the Neighbor Kingdom, offering a preview of the upcoming fantasy romance. The trailer likely showcases the initial interactions between Lady Tiararose and Prince Hartknights, hinting at the dramatic turn of events as Tiararose, reincarnated as the villainess, faces her impending downfall.

Produced by Studio Deen, known for works like KonoSuba and Shouwa Genroku Rakugo Shinjuu, the anime adapts the popular manga of the same name. The story centers on Tiararose, who remembers her past life as a player of an otome game and realizes she's been reincarnated as the antagonist fiancée of the main love interest, Prince Hartknights. The trailer probably teases the moment their engagement is broken at the graduation ceremony.

The series is set to premiere in Winter 2026 and will consist of 12 episodes. As an adaptation of a shoujo manga, viewers can anticipate a strong focus on romance and Tiararose's struggle to navigate her predetermined fate in a world she once controlled as a player.
