is this judged as the song ONLY, or best OP opening overall?
ah hell, its both Brand New World for me, with the Remix of We Are a close second. but like i said, if its the opening as a whole, animation included, than brand new world easily, because half of it is with Ennies Lobby stuff, which is by far my favorite arc in a anime ever (Fukurou and Franky punching the shit out of each other is such an awesome visual in the brand new world opening)
