I will get straight to the point, so let's start the story as soon as possible!
On the way back to her apartment, was this young woman called whatever you want because I'm lacking inspiration for names. It has been already several mintutes that she walked without paying attention to what was in front of her, the area being quite empty. Then came a disruptive event as in any story worthy of the name! Her foot tapped into a strange object by its appearance but also by the fact that it did not move even after the stroke.
This pyramid-shaped thing was nothing common. Absent-mindendly she tried to continue her way but then the object emitted light and it surrounded her. A voice came out of nowhere and asked her: "You that wakes me up from my eternal sleep (I found nothing better), you can have a wish. What will it be? ". She thought for a moment, then she said, "I want to be able to change things with a gesture! ".
"Wish fulfilled".
Then follows an even more intense light that disappeared with the object. Here is how her power works:
When she uses it (when she wants to at least), touching something will allow her to modify it in any way imaginable. You can guess that the main utility will be parts of the body or the whole body. The most common examples are the size or gender of this part etc. I remind you that animal transformations are forbidden. Touching with one finger will activate the change, and it will occur faster or with more amplitude with more fingers.
Snapping fingers can reverse the direction of the transformations (if it was growth it becomes shrink, the same for age or gender), clench the hand will reset the change.
You certainly ask yourself the following question: "How to change an entire body at once? ". Just make the gesture on the forehead (especially practical for the change of age or for shrink). I'm sorry but changing only the mind will be hard because it's not material but we are not here to philosophy but if you really want to let's say it works if you touch the head.
The adventures of our dear Lea (I lied I found her a name) begin when she returns home, with her boyfriend (you) and determined to test his new power.
