Her brain is fixed but empty

After a while, Kazex could tell her brain was functioning again. But she had no memory or anything. Her mind was like one of a newborn baby.

He knew he would have to teach and train her. It would be annoying but at the same time, it might help with making her a good breeding slave.

He started by showing her how to eat, sleep, use the bathroom, and all the basic and important functionalities she needs to keep herself alive and functional when he can't be there. But now he had to think of how to raise her brain.
