Tesagure! Bukatsumono

Same director, same no-budget MMD animation. Plenty of ad-lib, seiyuus telling bad jokes and going out of character. "I think this is a pretty weird thing to be recording at ten in the morning." Tesagure Bukatsumono will probably come out as the stronger of the two, but Gdgd Fairies is likely the easier one to get in to as it has less metahumor, banter and bullying but more slapstick instead. The cruder visual style of Gdgd Fairies is also likely to be easier for a newcomer to accept. 

Fundamentally the same kind of show, with a segment dedicated to a humorous look at a specific topic, and then another ad-lib section where the voice actresses improvise on the spot, all animated in CG.  

Extremely fast-paced shows using lots of short visual references to explain ideas and concepts one after another. Almost a quantity over quality feeling, to avoid polishing thoughts too much. Audiovisual Adderall. 

If you liked how "fresh" and different the voice acting is in Aiura, you will LOVE Tesagure! Bukatsumono to bits. The latter is also more well-done in the comedy department. Tesagure! Bukatsumono is suited for more advanced anime watchers, due to trope references and Japanese puns and lingo. Comedic genre: Wit & wordplay, deadpan and non sequitor. 

The voice acting seems weird and realistic in those shows ? no wonder why, I think they used the same process : give some context, characters to the seiyuus, let them speak freely about it, and AFTER the audio recording you make all the animation based on what they said. That's also why they use cgi models and motionless backgrounds most of the time in this kind of anime, since they're doing the audio before all the animation.  

Both are about a group of girls in a club who do nothing except talk about all kinds of random stuff. Personally, I dislike both of these two anime, but if you liked one of them, you might like the other as well. 

Ad-libbed meta-humour? Check. Crude CG graphics? Check. Nonsensical nonsense? Check. Koutarou Ishidate? Check.
