Kuro no Maou - Chapter 516

She was a medical genius from the Noah Medical Academy as well as a drug producing specialist. After sleeping for three days, she had returned to the ancient era and become the loyal marquis palace’s ignorant and silly young miss.

Yi Zaha. The crazy demon crazy for martial arts. While he was running away after stealing the heavenly pearl of the Demon Cult Leader, he fell off a cliff. After thinking that everything was over, he opened his eyes to see that he had returned back to when he was a waiter… And he is being beat up for something that he didn’t do.
