Tearmoon empire. Volume 1 - Nozomu Mochitsuki

Only to wake back up as a twelve-year-old! With time rewound and a second chance at life dropped into her lap, she sets out to right the countless wrongs that plague the ailing empire. Corrupt governance? Check. Border troubles? Check. Natural calamities and economic strife? Check.

My, seems like a lot of work.

Hard work and Mia don't mix, so she seeks out the aid of others, starting with her loyal maid, Anne, and the brilliant minister, Ludwig. Together, they strive day and night to restore the Empire. Little by little, their tireless efforts begin to change the course of history, pushing the whole of the continent toward a new future.

And why did the selfish princess have a change of heart, you ask? Simple-she didn't. She's just terrified of the guillotine. They hurt like hell, and Mia hates pain more than work.
