Just when frail and beautiful “court butterfly” Kou Reirin seems poised to marry the crown prince, jealous “court rat” Shu Keigetsu steals her body! Reirin wakes up in the dungeons as the conspirator, and things look dire…or do they? Now that she’s got a robust new body, not even the looming threat of execution can stop her!”
The novels were adapted into a TV anime which debuted on July 12th, 2026. The anime can be streamed on Crunchyroll under the title Though I Am an Inept Villainess.
