Oh gods, now I'm thinking that the chemistry buffs and magic users filled the dorms with hundreds of bunnies that turned into glitter bombs when touched. Glitter is literally the best prank item ever cause it never gets out! Literally the worst.

I'm not going to lie, I have an imagine of Nao having discovered glitter his first year at school and secretly stashing it in his bag cause it's so pretty. 

And clubs? Hm, I expect a ton of hero worship clubs. And a masive photography club. With flight, phase shifting, and teleportarion, imagine the angles they can get. They are probably an amazing place to hone your skills. I just imagine photography students trying to apply to the school just to be apart of that. 
And journalism club would be the busiest one really. With all the near disasters that must occur from bringing all these people together in one space, the journalism club is probably crazy. I imagine one of them running up to a person literally spewing flames at another, trying to get the dirt on the situation despite the now burning hair.
