Do-teihen Reijou ni Hyoui Shita 800-nenmae no Akujo wa Hissori Seishun o Tanoshindeiru is a light novel series written by Yui Regina. The story emerged during the height of the villainess subgenre in Japanese web novel culture, which frequently explores themes of reincarnation, redemption, and the deconstruction of traditional aristocratic tropes. It follows a protagonist who, having lived a past life as a notorious villainess 800 years prior, finds herself reincarnated into a social pariah and attempts to navigate her new reality while quietly enjoying the normalcy she was previously denied.

The narrative design focuses on character-driven humor and the contrast between the protagonist's sophisticated, centuries-old perspective and her current low-status situation. As part of the broader wave of light novels adapted from digital platforms, the series reflects the contemporary reader's appetite for stories that blend fantasy settings with slice-of-life elements. It has been received as a lighter contribution to the genre, emphasizing the internal growth and peaceful aspirations of a character who has stepped away from historical infamy.
