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.

The preparation for the oncoming war was in full effect. Everyone who could swing a blade was getting themselves ready for a battle of a lifeline, and perhaps if they failed the battle of everyone's life even those being cradled by their mothers. The Valkyries would not show any mercy not to the young, adult, or the elderly for their very purpose in life was to eradicate all life in precedence to the apocalypse.

"This is a huge gamble…" Fay muttered, glancing across the room at the workers moving around giant glass cases for the god-kin vessels to be produced inside en masse. "If even a single one of them goes against our expectations, who knows what kind of calamity might strike? With Asmodia, we didn't even get to know what kind of new powers she had gotten from the body."

Placing his hand on her shoulder, Haruki squeezed it gently to calm her nerves a little.
