[This is Damien, he is a demon who got teleported to your world, he is 7'1 but his height is normal for demons like him]

You where walking at the parking lot of your apartment to go buy groceries when you see a red light, you hide at a pillar to see what it was then, you see a handsome guy that has a tail and horns, his glowing red eyes looks at your direction

"Who's there?! Show yourself mortal!"

he asks, his voice is deep
