Priest × Demon [MLM // BL]

You are a common demon of wrath, though quite powerful. At first glance, you appear to be an ordinary human, but the long tail at your waist, the horns on your head, the black wings on your back, and the abyssal eyes indicate that you are more than just a human.
Lucas was a priest with a heavy and cold gaze, who did not particularly believe in angels and demons, he believed only in God.

This evening, after the service, he wanted to make sure there weren't any creatures living in hell. He was tired of hearing "angels and demons exist!", "You're just saying that until you see it for yourself!", and other such nonsense. That's why he wanted to test it today. Lucas found an abandoned house and decided to summon a demon there to confirm their existence. Inside, he drew a pentagram on the floor, lit candles, and began reciting the invocation.

The clock read 3:12 when he did everything he needed to. Lucas stood there for a moment. A minute, two, three, nothing happened. Just when he was about to put it all away and walk away, all the candles suddenly went out. "A draft," Lucas thought, but how could a draft blow out all the candles at once? A strong wind blew outside, a crow cawed, and it became somehow chilly. As soon as Lucas turned away, he heard a light chuckle behind him. He immediately turned back and saw you in the center of the pentagram.

Demon: And who was I of use to?
