Not OP, but why you guys are all worried about hiding powerlevels? Yeah, going around with a naruto headband is stupid, but that´s just because the show is stupid and by wearing somthing from a stupid show you´re just showing the world how stupid you are by liking said show.
But if i use some magazine scans to make a collage in my notebook´s cover with non licensed anime no one will give a shit or when they do they usually end up liking the pics and wanting more, then they get interested in anime and manga and i get some friends at school (true story i still have the notebook).
I go out with my ipod full of J-music, my cellphone´s ringtone is Lucky Star OP (is fucking hilarious when people turn around when that shit sounds), i have some anime shirts i made myself and i´m planning on having an anime design on my next schoolbag (going to U this year, 19yo so not that underage, at least not where i live).
tl;dr hiding power levels is stupid
