So it looks like the Nier derivative work guidelines include ‘Do not engage in conduct that is contradictory to public order and morality, or exceeds what is societally acceptable.’

But as I’ve mentioned before, I feel like the content of the Nier franchise itself already crosses those lines…

The full guidelines can be found here, complete with contradictory statements about not using fan works for “commercial purposes” and yet being okay with doujinshi sold at Comiket.

It would not be at all surprising if some artists do what many Evangelion artists did: delete their accounts and all the associated art.
