Umm without the doll joint it's not Rozen Maiden,may as well be some random anime girl in cosplay,it's not a fetiche is the way it has to be or it's not RM,cause well they are dolls right? Well IMO at least.
IDKY, but this group's stuff seems hotter when it doesn't actually show genitals (or the censoring that comes with it), where it opts for convenient censoring instead.
@Kiocat Then just go fap to the ones where they have doll-joints: those are kind of hard to miss. Leave us to fap in pe(nis)ace!
