When this sort of thing happens with BuCap in some Hakkayata doujin, it's more charming. But the girls in Love Live! seem way more grown up than in Saki, so it's a little disturbing. Probably because of the plushies, because Maki becoming a little girl in the OVA was definitely charming. It's heartwarming that NicoMaki would still be love even if one was a plushie.
