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.

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?

[Ding! User has successfully absorbed an intermediate beast crystal] 


it's been over six hours, since kyle and Vladimir stayed in the cave. the air had gotten chillier as it was night time, even the waters pressure had reduced and was moving much slower than before. 


Kyle had been absorbing the vast beast crystals he aquired, and had managed to boost his level up to 33. Since he had absorbed his first beast crystal and experienced the pain first hand, taking in the second was a little less painful to him. 


While absorbing the crystals he did notice a few things. 


Like one, whenever he finished absorbing a beast crystal his exp would increase a bit, until he reached the required exp point and levelled up. 


Unsettling feeling
