Tearmoon Teikoku Monogatari: Dantoudai kara Hajimaru, Hime no Tensei Gyakuten Story

Due to poor finances, an epidemic, and famine, the once prosperous Tearmoon Empire ultimately falls to a revolution instigated by its citizens and supported by neighboring nations. The rebellion also brings dire consequences for Mia Luna Tearmoon, the empire's extremely spoiled princess, who endures three years in the dungeons before facing execution.

By some miracle, Mia finds herself reincarnated as her 12-year-old self, retaining full memories of everything that had transpired. With the pain of the guillotine blade freshly imprinted on her neck, Mia is determined to use this second chance at life to avoid the grim fate that awaits her. She utilizes all her knowledge to improve the state of the kingdom and gather personal allies, inadvertently winning over the people's hearts and becoming beloved as a saint.
