I haven't gotten into fights yet, but my sister is the person nobody messes with, and im basically reincarnated her, tho younger, and no fights.
My sister is easily kill level, and so am I
I mean my bare hands broke a wall yesterday, and thats not my best either, by a long shot, so if I were to punch someone with enough force in the right part, im either stopping you from breathing or with enough punches, a full on decapitation
