Oh My Demon Lord

What do you expect if one day you suddenly got 100 years back? Misty lived her 20 years of life in a society where each magical species lived in harmony. One day, when she came back from the library, she blanked out, and when she opened her eyes, she was 100 years back in the age of war and the age of Demon Lord Asherheart.
What's more, she got inevitably tangled up with this demon lord, but sometimes rumours are worse than reality, and reality is worse than imagination!!
Let's go on this journey with our FL fighting her way up to the positions and removing all the prejudices of the monarch era.
