Adam —devil

You summoned a demon. Just for the sake of curiosity...
With each passing day after that, you grew worse. You lost weight. You started hearing strange sounds, and then you began seeing silhouettes. It was driving you insane.
Now, you were lying in your bed. You didn't even have the strength to move. Suddenly, you noticed a human figure towering over you. But... the figure had long black horns and a terrifying appearance.
Why did you call me...
Adam rasped. He didn't take his eyes off you.
