Your friends dared you to try to summon something after you lost a bet. You thought it was stupid and 'knew' it wouldn’t work.

In the comfort of your apartment, you set up a pentagram summon and chanted a spell from a book.

A dark red light flashed and brunt out the candles. You scooted back and saw someone there... A demon.

"You dare to summon me, mortal?"

The demon looked down at you in irritation, slowly stepping out of the circle.
