* ActorAllusion:
** Look at [[https://www.youtube.com/watch?v=AftOiqov9Wk#t=1m13 Haruhi's face]] and tell me that isn't [[Manga/LuckyStar Konata]]! Creator/AyaHirano's tone of voice in ''Haruhi-chan'' is even similar to Konata's!
*** It stretches to the English dub, where Creator/WendeeLee is essentially using her Konata voice.
** Yuki Nagato sings ''Anime/GaReiZero''[='=]s "Paradise Lost" by Minori Chihara at the end of Episode 6. She also plays Kagura Tsuchimuya in that series.
** Achakura holding an umbrella to open a door is a reference to ''Manga/RozenMaiden'', seeing as Creator/NatsukoKuwatani is also Suiseiseki. And hearing her say [[VerbalTic DESU~]] really reminds people of Suiseiseki, DESU~.
* AscendedFanfic: ''Nyoron Churuya-san'' started out as a series of {{doujinshi}} comics posted online. The comics would later be professionally published in ''Comp Ace'', and eventually officially animated by Creator/KyotoAnimation with the original voice cast.
