Once upon a time, there was a girl named Eve Reese who bore a striking resemblance to the Demon King he had once fought. With long black hair and the wings of Aen, she had endured a tumultuous fate before becoming a member of the man’s Koukyu and vowing to devote her life to him. Clad in a demure dress, she spent her days devotedly serving him. For her, those were moments of pure bliss. Yet the Demon King’s blood slumbering within her was not satisfied with that alone. One night, of her own volition, Eve transformed her black hair into pure white and dyed her skin a deep brown. It was the sign of her awakening as the true Demon King. Standing before the man clad only in a single towel, she begged for his cock. “More… more, pour all of yourself into me… Only your semen can make me who I truly am…” With every time she received the man’s seed deep inside her womb, her power grew. This is the record of a forbidden ritual in which love and devotion to a single man transform a woman into the mightiest demon lord.
