These parodies operate by dubbing snarky, sarcastic dialogue over the original in the series. Examples would be pointing out seeming plotholes or things glossed over, or events that the anime begins but we never see resolved, except in the manga, which may in fact be commented on. These parodies may be sounding boards for (or light mockery of) fan disapproval of certain story elements, like Kouta and Yuka being cousins.
