It's an intro quiz and KKKity team get it right so they flail a bit. The camera cuts to Ya-ya-yah (flailing as well) and then back to KKKity.
Koyama and Shige hold hands for a moment. (I went "AWWWWW" and had to rewind.)
Shige gives a shifty sort of look and pulls his hand from Koyama's.
I thought it was cute, so I figured I might as well share the love. ♥
You can DL the episode here. It's mostly a song intro game, so it doesn't really need subtitles.
