I finally watched haruhi-chan and Nyoron Churuya-san last month both of them were extremely funny, awesome, and even epic at some points like yuki's dating sim. Also Haruhi-chan's OP theme was simply hilarious, and fun to listen to. I really hope they make more or something like.
Also what it this "Nagato Yuki-chan" being talked of, it sounds like it is a 4-koma/manga or something and not animated?
