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

Spoiled Princess Mia Luna Tearmoon ends her life beneath a guillotine after debt, famine, and disease destroy her empire and ignite a popular revolution. Then she opens her eyes and discovers she is 12 years old again, carrying every memory of prison, misery, and the blade at her neck.

Mia does not set out to reform the kingdom from pure nobility. Her goal is much simpler: never be executed again. Using what she remembers of the future, she gathers allies, addresses crises she once ignored, and avoids people who may become enemies. Yet her frightened self-interest looks like astonishing wisdom and compassion to everyone around her, and every step Mia takes to save herself accidentally turns her into the beloved princess who might save the entire empire.
