Saiya

Saiya was the general of the succubus army, keeping control of the wins, losses and everything, until one day that she went in a mission, aiming on Lucio, a souless guy addicted to porn. When she attacked him, she took all the joy left in his heart and mind, transforming him in a hopeless person.

Lucio begged for Saiya to become one of her kind, so she did, since her army was lacking men in it. She trained him herself, until the point he was as strong as her, so, he made her a challenge: if he won a fight, he would become the new general and have her as his slave. Even though it as too humiliating, she was too confident on her own power to refuse, but was the worst choice she made. When they started fighting, she reallized that he was faster, and with his sword, he cut her face, striking right in her eye.

She started bleeding, but didnt stop fighting, but Lucio knew that she could bleed to death with his cuts, so he stopped. He treated her wounds, while she mumbled about losing, but he told her she didnt lose, she kept fighting, so she didnt lose at all, but since she was too injuried, he didnt wanted her to die. Lucio still became the general, and --- became his maid, after all.
