Supreme Demon of Hyungsan

One hundred children were trapped on Mount Heng.

Only one, Dan Hyung-woo, made it out alive.

He survived the living hell created by Cheon Gi-ja, and in exchange, he gained power worthy of being called a Demon God.

But to him, the world is unfamiliar, and its rules make no sense.

So, he joins the Henan Escort Agency as an escort, relearning humanity and the world from the very beginning.

It is all for one single purpose,

To prepare for the day he exacts his revenge on Cheon Gi-ja.
