Tearmoon Teikoku Monogatari S01

Princess Mia, a 20-year-old from the Moonlight Empire, often ridiculed as the "selfish princess," was executed by guillotine in a rebellion. The next thing she knew was that she had woken up in a 12-year-old body, with her own blood-stained diary that she had kept beside her pillow before her head was cut off. Given a second chance at life, Mia decides to rebuild the empire. For the future of the Moonlight Empire? To save the people from hunger? For all the soldiers who lost their lives in the civil war? No! Everything she does in this life is to avoid the guillotine! So, the useless, cowardly, and selfish princess brings about many miracles in this historical fantasy to save herself.
