>>34618813There is an anon who does variations of that one Vei reaction image. I mostly use the AI thing for shitposts, though a couple months ago I tried (and failed) to make an actual eldritch Nyan since I thought the concept art for her final boss model was fucking gay.
As for the sudden influx of art, I think it's because someone made one specifically for that. Most of the public ones are extremely gay and won't even let you do anything deemed NSFW.
