Wow lots to unpack here.
Smooth Operator is already becoming one of my favorite stands, I hope they each have unique dispositions and interactions with each other like Six Pistols,
Dragona's more like a crossdresser, maybe non-binary. Addressed as they/them but also as a brother but they also have implants,
Jodio is just like Jobin, a gofer, but he has a certain anger which we haven't seen in a main protagonist yet,
I'm starting to hate the green dude as much as Joshu,
These high schoolers are literally in Passione,
Meryl Streep seems like the main villain to me, but I don't think they'd reveal it first chapter.
