I'm totally in that Chihiro x Keima ship too. FEEELS.
It was surprising seeing so many smoothly animated scenes too. Normally they only have one at the end of an arc but there was a whopping THREE. They were all so beautiful too.
The wings during the performance was my favorite, I think I audibly said "holy crap that's cool" when it came on. It was awesome. xD Gonna try and start reading the manga soon too. This is one of the first series for me that's actually worth reading back from the beginning after watching the anime cause apparently they skipped a lot of good conquests. During the performance there was a montage of clips with past conquests and I'm pretty sure I didn't notice 4 of the girls so it'll be nice to see their arcs.
