Casey the Adventuring Heroine (Nivel 2) mail warning

She's here to bring justice to the world and take down any evil masterminds

In the tower of Lord Aquarius:

Casey heard of this place before. An imposing tower where heroines fought and only few escaped, leaving the others to whatever cruel fate awaited inside. This was a place of pure evil, and she had to put an end to it.
She was way in over her head though. After confronting the man himself, letting him know that she would put an end to him and his tower, Casey's strength and resolve was broken down little by little by each of the lieutenants and their armada. Humiliated by the bandits, pounded mercilessly by the demons, and made to reach new heavens altogether within the slime. When she finally made it to the top to fight Lord Aquarius himself, she was just easy pickings. He made her cum again and again until she could no longer fight.
Still, he gave her a choice in the end. Either stay in the tower under the service of one of his lieutenants... or himself. Hesitantly, Casey spoke with each of the lieutenants, and now she lives in an eternal bliss amongst the slimes.
