After slumbering for years in the darkest pits of the abyss, Haruki Shin is awoken by the demon lord of lust. She tries to remind him of a contract he signed with her in exchange for the power that would help him exact his revenge in the mortal world.
However, who or what he wanted to get revenge on? He couldn’t remember. Replaced with a hazy mist, his memories had long since faded. But to the mistress of lust that didn’t matter as she forced him back into the mortal world with the demonic body of an incubus. 
Feeling lost he’s forced to adhere to each of her commands, and despite his refusal, he can’t resist the binds of the contract. Eventually, however, as he learns more about his tragic past, and the existence of the lustful system he’s been blessed with for his revenge, his path to becoming a monster finally begins.

Absolute Depravity: Reincarnated with a lustful System

In the land of toxic fumes and enigmatic monsters, the morning brought not the sun but a deep hue of deep red dark. The clouds, the shadows, and even the air itself were oozing with the blood of a hunt far from the sight of the observer.

Scanning the surroundings with shadow clones, and scattering demonic spies all over, Haruki had successfully surrounded the watchtower that had Asmodia's body tomb underneath. Making use of her new ability, even Riley had sent some of her invisible clones inside to scan the tower and figure out the position of the guards.

Once the place was all but mapped up, the clones and the demonic spies were led up to a door sealed with strong arcane magic, and vast arrays of true holy magic circles.

"That must be the room," Haruki mumbled, opening his eyes after seeing the door.
