Nikun's Manga

This is the first time Ive come across a character like the demon lord. He potray himself as a demon god and act like one. Not like the typical cliche villain but an omnipotent figure look down upon his subject. Very cool character. And the story is hella addictive and amazing !!

PLEASE IT WAS GOING SO WELLL BUT THEN SHE STARTED TO BE EXCESSIVELY METICULOUS AND GETTING AFFECTED BY THE PEOPLE AROUND HER …. Is there any manga where the female lead actually kill and did their revenge mercilessly
