"I'm not evil, I'm good... with a twist."

Prideful. Arrogant. Cold. Three words that perfectly describe 19-year-old Goo Junhoe.

No one knows who he really is, what he really does or where he really lives. He's an incomprehensible man living in the shadows that the city's skyscrapers offered. On Earth, he's just another student, another boy. Deep down, Junhoe holds a really dark, twisted secret that only a certain creature knows - he's a demon. A demon of pride, Lucifer. He's Satan, created not to serve, but to be served.
