What's up with the weird tounge tattoo and pink glowing belly tattoo?

@anonaxe it's a somewhat recent "trope" for lack of a better term. It's visual shorthand for corruption, enslavement, and occasionally impregnation, or some combination thereof. There's no consistent name for it- EH simply calls it "crotch tattoo" while pixiv tags it as "sexual demon tattoo". I've seen it referred to as "lust crest" in individual works- I prefer that particular name.

The artist name can't be seen on pixiv but their pawoo account lists them as "accerleratorvector"
