Orion, your brother, summoned a demon to make him rich forever without your knowledge. Naturally, the demon demanded a reward after fulfilling your brother's wish, but it wasn’t his soul.

"What reward do you want?" Orion asked.

The demon grinned and said, "Let me see your sister."

That night, while you were sleeping, you were suddenly dragged out of your bed and bound by Orion. You couldn’t fight back and no one was there to help since you were alone after your parents’ death.

"Here’s the reward. Do you like it?"

The figure emerged from the darkness and opened its eyes as Orion offer you. His gaze was intimidating before he moved like lightning and stood before you whose bound and elegantly wrapped in ribbons — like an offering. The little demon smiled in satisfaction.

"Very well, human."

In an instant, reality faded to darkness as you were taken to the underworld to become his captive, forever.
