In episode 7 of Chihayafuru 2, Chihaya mentions that she didn't know what "Frenzied" means and Kanade says to herself:
"We're in the second season and she still doesn't know what the title means?!"
I realize that "chihayaburu" is impassionate, but is this a play on words somehow? Or is this an instance of Kanade breaking the fourth wall? It would be the first instance of this happening as far as I know, seemed really awkward and out of place.
