Demon Core meme came from KanColle(2013) communities in Futaba, and permeated to nicovideo.jp as well as to Twitter. That's why it is predominantly image based with few GIFs inbetween, why it is Demon Core and Demon Core only, and why there are few comical non-girl versions created years after inception.
I'd guess overlap between outspoken (ex-)Futaba users AND HN readers(hops_max=3) OR knowyourmeme users is exactly 1.0f, and this won't ever go on record anywhere unless someone say it somewhere, so here you go.
