Nina
She'll be there for a few hours at the very beginning, then will bid her adieu~ She may even attempt to dress down for the occasion (some sort of casual dress or even jeans and a flowy sort of blouse).
Most of my threads these days are with Nina so I am going to try and get more things for my others, but please feel free to ask if you want anything with her and I'm definitely up for headcanoning also :)
