[@Melkor] I'm cool with character development, just trying to avoid a scenario where he ends up wanting out or something.

Well, in the source material, they treat quirks as bodily functions and they improve in certain aspects. For Ara, on the top of my head, improvement could be increasing the number of people he can read at a time or tolerating mental fatigue since he's perceiving more stimuli that the usual human. They do a bunch of quirk training in the anime and manga, so its easier to understand. I could give you other examples but that'll spoil it for you.

[@OwO] I think all bases are covered. Just for clarification, aside from the whole shedding and manipulating of skin, she can also propel it and in a way, move it around in a telekinetic-type manner?
