He decided to start with Mary. He looked through what he could do and found he can change her race, sex, mentality, looks, etc. Basically anything he could think of it can be changed. He decided to change her appearance. He thought about what to do and remembered she wanted to be a cat girl maid to some jock in school. He decided to grant that but with her being a maid to him. He saw he can make it temporarily or permanent and choose permanent, after all if this is real then why not take advantage of this. He made it so only the two of them will know of the changes and no one else will notice. He made it so nothing else in reality will not be changed but Mary serving him and no one will pay attention to that or if they somehow do, they won't do anything to change it and she won't be able to escape from him nor be able to use the Chronivac , learn about it, or have someone else change her back.
He tapped begin and looked out to see Mary leaving the house when the changes started. He saw her collapse on her knees as her clothes changed into a maid uniform and cat ears and tail appeared. She entered the house and came to him. "What the he'll you do to me?!" She demanded. "I made you my maid as payback for lieing to me. You will never be free from me and any attempts will be having you trapped in your own mind as another personality that is submissive to me will be in control for some time. Each time you try the longer it will be and till I decide to have it be permanent just to not deal with you anymore." Ken told her. Mary shook her head in disbelief and decided to leave. Ken decided to show her that he was telling the truth, with the personality in control for 24 hours. His maid turned around after stopping. Her eyes were slited like a cat's and her eye color is purple showing the submissive personality was in control. He ordered her to make dinner and then clean the house before heading home and acting normal before coming back tomorrow. He was glad it was the weekend.
His mother was not coming back till Wednesday due to being on a trip. And school has just started. He thought about what to do next. Get payback? Improve his life? What to do...
