Description

In front of the slave protagonist, Nil, a demon appeared.
"You are the forsaken child of a royal bloodline," the demon declared,
"How about using my power to control humans and get your revenge?" it proposed.
With newfound power obtained from the demon's pact, Nil slaughtered his twin brother and took his place as crown prince.
His hatred then turned toward his mother, the queen, and his sister, the princess.
What fate awaits a man who wields inhuman power?
