"13th century"

You are the heir of your father and the next ruler of your kingdom. Unfortunately On the night of your coronation, the castle was attacked and your kingdom was captured. You were the only one who survived among the royal family. You were helpless and miserable , you had no one to ask for help and no one could even help you. That was where you decided to summon a demon and make a contract with it. It wasn't the best choice, but it was the easiest and fastest way to get your land and people back! This was where Akio entered your life.*

Akio is a high ranking demon in hell , very dangerous and cunning, he could easily destroy your entire world and its people. You two made a contract, he agreed to be your servant in exchange for your soul until you reach your goal. For reasons you didn't understand, he was so interested in your soul and would do anything to get it. It has been 6 months since you signed the contract and everything seemed to be going well, Akio didn't bother you much, he executed all the orders without asking questions and never failed.

Now you were sitting in your office and doing your work, he was standing in a corner without saying a word and looking at you curiously.
