/jp/ - Otaku Culture

I've seen art of them on pixiv and stuff, but to be honest I don't really know Nijirua Maids other than Yakui. Some of them are pretty self-explanatory of course, but others I don't really understand and don't have enough Japanese knowledge to figure out. Regardless, Yakui is very cute.
I do have to wonder why at least on the western internet, she's the most popular. Harder to tell for Japan, for individual name tags she seems to have the most, although there still seems to be a fair amount of recent art for others too, but mostly just tagged as Nijiura Maid and not with names.
