Sebastian Leodegrance was fated to bring about the world's end, his path irrevocably marked by the three scars etched across his left eye as proof of his unholy contract with Ardalas, the Evil God.

His insatiable thirst for power would have been enough to conquer all, even without the infernal blessing, but now not even the divine intervention of the Goddess could thwart his ambitions.

With purposeful strides, he marched toward Cassiopeia to claim the hand of the renowned Princess Ava Cassia, a woman whose veins coursed with the blood of greatness. But as he drew closer, he discovered that the Princess had been exchanged with her Lady in Waiting.

"Yes. I am the replacement. You have been fooled!"

"From now on, Isla, call me Elder Sister."

The person in front of her was the brightest constellation in the world. Ava Cassia... the Princess who was even prettier than the Nereids. But it was like looking in the mirror.

She looked exactly like her.

"Maybe the Goddess sent you to me so we can become Sisters. How about it, my dear Isla? Would you call me Sister?"

Her most cherished treasure; her Elder Sister, Ava.

"I'm sorry, Sister... this is the only way."

"You must replace me. Because if I bear his child... this world would perish..."

The Tyrant's Replacement Bride

At first, it was just a small sensation. 


But now it felt a bit ticklish that it disturbed his sleep. 


It reminded him of the cat he used to take care of when he was still little. Her paw would scratch and tap his face softly and carefully until he woke up. 


Sebastian frowned in his sleep. He whispered, "Dorothy, stop. I'm awake." 


He opened his eyes, catching the little paw that disturbing him with his hand. But then, he realized something. 


It was not his little Dorothy that had disturbed his sleep. In his hand was the hand of a woman who slept with him last night... the Princess, Ava Cassia. 


And this world had changed under his influence. 


He smiled at the woman who was lying naked beside him. He asked, "My fair lady is awake?" 


Isla narrowed her eyes. Dorothy, huh? She bet it was one of his concubines he liked so much. To hear this monster call a woman's name so affectionately, she was a bit surprised.
