You think the best person for his first test should be his sister Saya. Selecting her, he saw she was wearing her school uniform of black pants and a white shirt laying across her bed reading a book.
The first thing he does is turn off her awear ness, he doesn’t want her freaking out.
Next he does is open up he stats and get to work alternating her appearance.
He starts by adjusting her body settings, making it so she never has to shave her legs again by removing all her body hair below her neck. Your welcome Saya. In exchange You make her hair blond and lengthen it down to her knees tying it in two blue ribbons that give her long twin tails down to her knees.
Now he adjusts her cup size slider, going from her modest B cup to full on E cup. Now you gave her some extra wait in her hips, while also keeping her stomach slim.
Finally You decide to make her a head taller than your self, to make the older sister appeared complete.
Now to make her even more like an anime, you get rid of all her skars she has earned, making her already airless skin even smoother. You make her eyes bigger, and more pronounced while also changing her nose to be smaller.
Now for the finally you change her out of her boring pants and shirt, and into a sexualized anime schoolgirl out fit.
One that has the first three buttons unbuttoned around the blue scarf unbuttoned to show off her E cup breasts.
With the top and skirt being separated to show off your sisters recently well toned midriff.
The dark blue skirt was so short if she took too big a step you could see up her skirt and get a peak at her red panties.
You also threw in some clean white socks that go to her knees.
Once done with her appearance you move on to your sisters mind, making her more confident and comfortable with her body, so she’ll wear less clothes more often, and not be embarrassed about you seeing her naked or in just a bra and panties. You even increase her normal body heat, giving her even more of an excuse to wear more skimpy and revealing outfits, or just sweat so you can see her pink bra through the fabric of her outfit, you also make it to were you will be able to take a bath with your hot sister without issue, because why not?
After double checking to make sure your sister was to your standards, you begin the changes.
Just as you had specified your sister is ignorant to the changes.
Her body gets longer, her skin gets smoother, loosing all body hair below the neck and becoming smooth and flawless. Her chest and ass balloon from B to E almost ripping her clothes, but just in time they alter to be the skimpy school girl outfit you designed. Her hair grows long and ties it self in two blue twin tails at the sides of her head. Her face changes to be more anime like with bigger eyes and a smaller nose. She adjusts her laying down position to compensate for her new breasts and ass size but otherwise doesn’t seem to notice her new body.
Yes. Test one of making the whole world anime is a success. Now fo—
You sister knocks on the door interrupting your internal monologue of phase two of your plan.
Next she opened the door.
Your jaw dropped on the floor, your sister looks like she could have come right out of a screen she was so close to anime.
“Jay- Chan where going to school so you better get ready.” You Sister Says to you.
You simply respond: ‘in a minute I just have to finish up this thing on the computer.’
Saya shrugs and leaves your room, her skirt fluttering in unseen wind.
You definitely underestimated just how hot you made your sister.
But no time for that, she was taking you to school. You needed to make one last change before you started getting ready to go with your sexy older sister...
