Since I made it very clear that I think Pencil is mcbling I should probably clear up the other freesmarters:

Match is manba gyaru, Book is whimsy twee, IceCube is maybe cyber angel, Bubble is cleancore/safetycore, Ruby is a mix of hyperpop and nerdcore, and Needle is maybe fairy grunge(???)

so ruby isn’t a nerd. unless this is some au where the personalities swap but even then ruby wouldn’t be a fucking nerd.
