Alethea stood at the edge of twilight, a figure straddling the sacred and profane, cloaked in human flesh that barely concealed the infernal fires beneath. Her beauty was a mask, her voice a siren's call, lilting with promises of protection and devotion. She breathed lies as easily as air, each word slipping like silk around the throat of her chosen prey.

"Calvin," she whispered, the sound curling through the gloom. "You need not fear me. I only seek to keep you safe."

The air grew thick with the scent of decay, the cloying perfume of ancient temptation. Calvin, a man anchored in faith, clutched his rosary so hard his knuckles paled. His heart beat against his ribs like a frantic animal, but his thoughts held firm, fortified by the Scriptures that warned against the Beast's seductive touch.

“Stay back,” he stammered, eyes wide, the cross held between them like a blade. “You are not of this world. You are a creature of darkness.”

Alethea's gaze softened with an almost imperceptible sadness, a crack in the veneer of her monstrous facade. "You speak of darkness as if you truly understand it," she said, her voice as cold as the grave. "You cling to your faith, your symbols, as though they could protect you from the reality that lies beneath your skin. We are not so different, you and I."

Her eyes, black pools that swallowed the light, seemed to plead with him to see beyond the horror, to recognize the fractured soul trapped within the demon's form. But Calvin’s grip tightened, and his lips moved silently, reciting prayers he had learned as a child. The holy words fell from his tongue like ash.

“Get thee behind me, Satan,” he spat, though his voice quivered. “I will not succumb to your wiles.”

Alethea’s expression darkened, the illusion of warmth draining from her face like a sunset giving way to the night. Her features sharpened, revealing the contours of something ancient and hungry lurking just beneath the surface of her skin. The sadness in her eyes flared into rage, a cold flame that burned without heat.

“You fool,” she hissed, her voice reverberating like the tolling of a funeral bell. “You speak of salvation, but you have damned yourself by your own hand. Had you not recoiled in fear, I would have shielded you from the evils of this world until the stars themselves burned out.”

The shadows around her twisted and writhed, alive with malice. Calvin stumbled back, his faith wavering as an icy dread clawed its way up his spine. In that instant, the mask fell away, and the full horror of her true form unfurled before him: a thing forged in the abyss, its skin a darkened marble streaked with cracks through which a hellish glow seeped. Her mouth split wide, revealing rows of needle-like teeth slick with hunger.

A scream clawed its way from Calvin's throat as she descended upon him. Her nails, sharp as daggers, raked his flesh, and her mouth, unhinged and yawning like a pit to oblivion, latched onto his throat. As she fed, the life drained from his eyes, the rosary slipping from his limp fingers to the cold earth below. His soul, severed from its mortal tether, slipped into darkness, vanishing like a final breath on the chill wind.

When the feeding was done, Alethea stood amidst the carnage, her hunger sated but her heart hollow. She knelt beside Calvin's body, her bloodstained lips trembling as she whispered, “I would have loved you.” Her words fell into the night, unanswered and unheard, a lament carried away by the wind.

The silence that followed was suffocating, and Alethea found herself staring into the void, a creature born of darkness yet grieved by a love that had been poisoned by the prejudice of mortal men. In the end, she was left with nothing but the taste of regret and the certainty that true damnation lay not in her infernal nature, but in the hearts of those who could only see her as a monster.

The night wore on, and the demon wept tears of blood over a love that had died before it had ever truly lived.
