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

Left behind in the dungeons with the queens, Margarette was turned in charge of the army's renewal and their deals with the other species. The humans were the least of her worries as they were easier to control given she'd been one at one point herself, the demi-human tribes and monsters on the other hand were entirely different things.

"How many?" She asked the female goblin guard walking alongside her.

"Three leopard-men tribe, one kobold tribe, and a hive of vampires," her eyes fixed on the clipboard in her hands, the goblin guard kept leading Margarette towards the burrowed newly built prison on the lower levels of the dungeon. "From the goblin party's report mostly the women and children survived from the monster tribes since most of their soldiers consisted only of men."
