After watching this episode the second time, it's still god damn hilarious. That hair cutting scene made one hell of laugh trip.
IIRC Ueno is Kigami's apprentice. Ueno really did a good job with the animation and this time the style is what you'd see from Kigami's old works.
Regarding the build up, I'm really itching to know where Rikka's story is going. That train scene was so eerily beautiful. I know it's just me and my twisted thoughts but I can't help but think of something very tragic. I know that's not gonna happen here considering how light the show is. But if it does.. Well I'll be damned....
