well the japanese authors are very tolerants, it is true, but occidental/western enteprises which had the rights of diffusion and commercial market for their creations elsewhere than in japan ae not... I am sure sailor moon "mother" (cause the author is a woman) would more gladly give her willing approval for a poser suit than for x rated doujinshis (not that she refuses or grant her approval for doujinshis or not, it is not the matter), but rosity won't... the trouble is here ! some "authorisations" do not worth anything in some contexts.
