Hey what's up
I think I did pretty ok on my Calculus test and I'm effectively avoiding studying for Differential Equations so I'm going to make you a list of my favorite UR cards from School Idol Festival.
I'm going to split them between unidolized and idolized because there's really no way to compare the two.
