The Kept Man of the Princess Knight TV anime will begin airing in January 2027. The announcement comes with the reveal of the show’s teaser trailer and teaser visual.

The Kept Man of the Princess Knight (Himekishi-sama no Himo) is based on the Toru Shirogane-authored, Saki Mashima-illustrated light novel series that started in February 2022 and has six volumes as of 2025. Yen Press describes the light novels’ synopsis as such:

The Dungeon City is a wicked place filled with crime, debauchery, and death. Its one shining light is Arwin, the beautiful Crimson Princess Knight. She and her brave party of adventurers descend into the dungeon at the city’s center, seeking a legendary treasure with the power to rebuild the princess’s fallen kingdom. Many yearn to be by her side, but that spot is already taken by Matthew, a man despised by all in town as a cowardly weakling. Everyone thinks he is scum who just spends her hard-earned money on booze, women, and gambling. No one in the city—not even the princess knight— knows what Matthew is truly capable of.
