>>8534302Like a full series focused on female characters eating people? Likely never, outside of some small crowd funded/passion project type thing. Though I doubt anyone is going to put the effort into a 2d animated project beyond 5-10 minutes centred on vore.
I can only see two or three possibilities to actually see a giantess eating people in an anime:
1. A horror short or something - mostly with hard vore/gore of a woman shrinking and torturing people, if there's soft vore, I can see it as a moment of particular cruelty, like the woman putting a character's sibling/best friend/lover in her mouth, and as the character begs, she swallows them whole. But nothing else beyond that.
2. A gag on a character growing giant, accidentally eating someone (who's later let out), or intentionally with some omake/outtake thing at the end of the episode
3. Incredible voyage/intentionally getting swallowed, like a character grows into a giant(ess) monster and her friends have to get some magical whatever out of her to stop her rampage.
