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?

"D-don't hurt him." Lumia muttered, her eyes slowly fluttering open. What met her eyes was a tall green coconut tree, accompanied by the soft gently breeze. 


"W-where am I?" Sitting up straight she looked around, as she seemed to be in some sort of green terrain. Green tall trees were everywhere, followed by exotic birds of all kinds making her wonder if she was in some sort of jungle. 


'This can't be right.' Lumia rubbed her eyes couple of times, thinking she was still dreaming. But no matter how hard she tried to convince herself this wasn't real, she just couldn't. 


"Argh!" she immediately clutched her head, as memories of what happened flooded her head. 


"N-no.." she weakly uttered, her eyes becoming teary recalling the traumatic experience. 


"He can't be dead. He's the king, yes.. h-he'll make it just like he does with every other battle." Balls of tears streaming down her cheek.
