Sorry, I'll have to do an ENTIRE canon review / history review of Nobunaga before I'm comfortable unless God gives me a shortcut and if I get that <- I'm prioritizing the world saving >>
I accidentally did this to Moosey. I didn't know he purposely hunches to keep blood flow to brain (weird) and spinal position can go a long way to helping detox
She's Queen Kong gyaru and a pun on gorilla -- without her makeup she looks like a gorilla and instead of expecting society to change (or trying to change society about it) she studied the shit out of makeup and her dream is to be a makeup designer
But yes, her "attack" wasn't really an attack, it was straightening Kuroe's (Psycho-tan's) spine so that she didn't fuck up her health/beauty. Most girls that are hunched over are unconsciously trying to protect themselves because they're scared of classmates and that fucking introverted and not confident etc.
