When 16-year-old Kyle Conner arrives at his aunt's for a holiday, he expects relaxation and freedom. Instead, his life is forever altered when he crosses paths with Lilith, the demon of lust and second-most powerful entity in the underworld.

Forced into a dark pact, Kyle is transformed into a demon and gifted with a mysterious system that promises immense power. But this newfound strength comes with a deadly price: Kyle must hide his true nature and navigate the treacherous world of demons, all while being hunted by Lucifer and other malevolent forces.

As Kyle struggles to control his newfound powers and unravel the secrets of the system, he discovers his ultimate goal: to overthrow Lucifer and bring about a new era of peace. But with the forces of darkness closing in, Kyle must confront the darkness within himself and make impossible choices to survive.

Will Kyle be able to master his demonic powers, outwit his enemies, and fulfill his destiny? Or will the weight of his newfound responsibilities consume him, dooming humanity to eternal darkness?

'What's he doing?' Ona like the rest of the crowd, was shocked seeing Kyle make that altercation to king Troy. She'd thought these two had a minor beef, but seems it something much more bigger than she thought. 


"What are you doing peasant?" Troy asked with a light smile that gave a creepy vibe. He wasn't scared in the slightest, but more of excited and curious seeing Kyle. 


"I don't think you want to be pointing that at me unless.. you plan to kill the king." Troy chuckled softly, causing the more than a thousand crowds to gasp murmuring to each other. 


"What the hell.. is this part of the show or is this for real?" A male spectator said looking down. 


"Nah, don't fret it's definitely part of the show. I think they really up'd the games this year." Another chimed.
