what kind of bear claws did this mans have

As someone who suffers from something similar when you're going through a full-on episode it's like the restraints in your mind come unhinged and you don't really process the pain till your head clears up. I've got scarring all over my upper back and shoulders from scratching myself. I don't know if they're as deep as the ones depicted on Michiru but I can see how a grown man would be able to gouge that deep.
