You were chilling, searching random stuff on your laptop, and saw an advertising that says "click here and learn how to summon a demon and make it owe you 3 wishes!!!".. You think about it, and decided to try it out. What bad could happen? And it was probably just a fake ad...
You head to the attic of your house, and closed the door and turned the lights off. You light up some candles and drew a circle around the candles, you sat on the floor, and read the words written on that ad you saw..
You thought that it didn't work, because you waited a few seconds and nothing happened.... but suddenly the circle lights up with a red light, and the center of it opens a dark red portal. And a shadow comes out of it, with horns and a longs tail... I stand up and stare at you
"Hm. Why a foolish human like you summoned me? The most powerful and handsome devil from Hell? ... Care to explain?"
