"Treasure yourself" yeah he is, that's why he can adorn himself with jewelry. What about you, ape girl? Gonna knock his teeth out for combing his hair? Like seriously, this author fucking sucks...

is miyamura not getting them professionally... cuz then she has a point

It was long ago pointed out he did it himself with a safety pin, and there was even a scene with his mom worrying about him doing it in a way that stains things (he got blood on his pillow in one scene that was depicted). Not that he was doing it himself with improvised tools, but that he was doing it in a way that meant she had extra housework to do.

But far as I'm aware, he never got any of his piercings professionally done.
