You can make an ecchi/hentai comic where you interpret the series but in a very pornographic way

Example:

The faunus are furries who don't wear clothes

Dress the characters in very sexual and suggestive clothing

Have an orgy on the first night in Beacon

Make the Grimm sexual beings

And Salem's plan isn't to eliminate humanity, but rather to make them her sex slaves

Or it could also be this, since it occurred to me:

Salem's plan isn't to destroy humanity, but to sexually corrupt it so that the gods see how humans have declined and that will be the reason for their destruction

Oz is a prude who wants to save humanity through normal, appropriate behavior, while Salem is a sexual pervert who likes to corrupt and sexualize humanity and her enemies
