be a burnin' star if it takes all night

Scars are the product of strain from overuse, as her powers are based in a form of electromagnetic radiation which is conducted through her body. It causes burns similar to lightning scars except she’s burning herself from the inside rather than being burned, if that makes sense. There is a safer way to use the form of crude electricity she can produce (picture 2) but BLi didn’t teach her that because obviously, so it is used somewhat sparingly.

To mitigate injury, she can use the knives (picture 1) which are basically ray guns except the stuff that would usually be shot out of the barrel is conjured by The Girl into the form of a fixed plasma/excited hydrogen molecule blade thing that will basically kill anything it comes into contact with, if not cause a severe burn, because it’s essentially a condensed star anchored to a special metallic conductor built into the hilt. This transfers the energy from her body to the blade, which takes the strain off of her and results in far less scarring.

The Girl being the most powerful of those who can actually use this “magic”, she can handle more than the average person. For example, conjuring a fixed blade would be nearly impossible for anyone else, and using even the tiniest amount of crude electricity could send a less powerful user into cardiac arrest or cause a major stroke. The Girl can do these things with relative ease save for the incredible discipline and practice it requires, but once she’s past that it comes quite naturally.
