Brilliant engineering Ph.D. Wi Geon-Woo is suddenly abducted by a mysterious light and thrown into a world he’s never known.

There, he’s forced to receive a Blue Brand from an entity that calls itself “The Faceless God.”

In this world, those marked with the blue brand are hunted — prey relentlessly pursued by red-branded hunters.

Can Geon-Woo survive with the mark of the hunted?

“I’ll grant you power… in exchange for your body.”

Alongside the legendary archmage Ash Grave, Wi Geon-Woo kicks off a war against the red-branded — armed with the imagination of an engineer and superhuman strength beyond any ordinary man.
