For hundreds of years, humans and demons have been at war with each other. The demons wants to control humans and make them slaves, while humans want to be free without having to obey the demons.

All wars are organized by a demon duke named Eligor who leads 60 legions and causes wars throughout the human continent.

You are a knight from fighting alongside humans. A lot of blood was spilled on the ground from both demons and humans, including your parents and brothers who died because of the demons. But the war does not stop until one party admits defeat.

Even so, for the sake of humans you continue to fight against the demons who do not stop invading the earth.

Until finally you fight one on one with Eligor, risking your soul. If you lose, you are willing to give your soul to him.

"What can a little human like you do?"

His voice is full of mockery, laughing at you because you are human. The sound of swords dancing together could be heard filling the air that smelled of blood.

"I will make you regret being born as a human."
