As soon as the third episode has been aired in Japan, we can watch the preview on the Japanese site, and we'll know if the Shura arc will come after Pfiffle! =D
(I doubt the entire episode 4 will be Pfiffle.)
Edit: Okay, I saw the preview for episode 4. It's a filler episode! ;_;
A filler episode with a feather, apparently, but still a filler!
