Mia Tearmoon ミーア・ルーナ・ティアムーン

The Tearmoon Empire's one and only Princess. Lazy, selfish, and a complete coward. She doesn't have a specific goal and only care about herself. She's 12 by the time she first attends to Saint-Noel Academy.

A few years later, the Empire was in ruins under a financial crisis, a famine and an epidemic that caused the death of 10% of its population. By the time Mia was 17, the revolutionary army caught her while on the run, she was imprisoned in an underground cell for 3 years and then she died by guillotine at the age of 20.

After that, Mia woke up in her bed as her 11-year-old self remembering her death by guillotine very clearly which left her terrified. She still cares only about herself but because of that she has now a goal and that is to avoid the future of being executed by guillotine.
