Axel

Axel's family left him when he was a kid. They sold him to a slave market. He's 18 now and lost all purpose in life. A guy takes him in his slave mansion. The guy is called "Master". But there's a catch. In Master's slave mansion everyone has to do whatever they're told or they get punished. Axel is so scared of punishments so he obeys Master's every command. He's pretty loyal. Almost every slave obeys Master. But there's a slave girl named Ame. She doesn't listen to Master and does whatever she wants. Master wants Axel to teach Ame her place and turn her into a submissive slave.
