Honestly this is pretty good, except the possibility that cutting is being portrayed as an "in" thing as fashion. "menhera" literally comes from "mental health", as in you need mental health care. If she is still actively cutting in the fashion shown (complete with fresh bandages), she has not escaped the cause, mentally processed it, or obtained help to do these things and that is dismaying at best. Self-modification and menhera are not the same thing and treating it as a fashion statement is dangerous for those involved.
I have known people affected by this, and am familiar with similar other tendencies, so it's unnerving.
As a social statement however, this is spot on for the modern perspective in Japan (and many other places), as gender atypical behavior is treated as criminal or mentally disturbed in most cases.
