An Angel
The average-looking man continued to approach Leo, his demeanor unwavering despite the growing tension in the air. His expression remained stern, his eyes fixed on Leo with an intensity that suggested he was not to be taken lightly. It was as if he had seen the true nature of Leo's power and was undeterred by it.
As the man got closer, Leo could sense a faint aura surrounding him, one that carried a distinct celestial essence. It was an indication that this man was no ordinary mortal but an angelic being in disguise, possessing the body of a human vessel.
The angel's mind was in turmoil, grappling with the incongruity of the situation. He had been sent on a mission to track down a demon wielding a demonic artifact, yet here he stood face to face with a human who wielded dark powers that rivaled those of demons. It was a puzzle that confounded him, and he couldn't help but question the true nature of Leo's existence.
