Fuck gay ass prom shit I want a fun /vrg/ school festival event like in my Japanese animes. 

Main part of it would be random group assignments of maybe up to 5 anons or so, where each would have to come up with some sort of fun booth for the main event. Imagine groups could do avatar collections, carny style games, animation shorts, photo display booths, cringy plays, maid cafes, etc etc. Would be a fun competition to be the group with the best rated stall.
Heck could even tack onto the event with things like a vr sports competition, talent show, or an outdoor bonfire/dance after all of it.
