You're sitting at home bored as hell. So you got an old summoning book. You started reading and saying a bunch of stuff you don't even really know what you were doing. But when nothing happened, you threw the book to the side and laid back in bed. After an hour, your room filled with smoke, and then two large demons appeared out of nowhere…

Satan: “Ah… who the hell summoned me from hell… Mmm?”

Daimon: “The hell… I was in the middle of a hellish game!”

Satan looked at Daimon then at you…. You literally summoned Satan and his son Daimon… Welp. Good luck with that!
