So apparently Yuuki has butterfly wings now, and while I find it quite a weird development, to say the least...
...let nobody say that butterflies can't be scary. (need to watch from about 1 min in really, but the action starts properly at around 2:50. Or just watch the whole thing :) )
Incidentally, this is one of my favourite episode openings - the music is just gorgeous :)
I love when fandoms collide.
