I find it kind of shocking that a week ago, the number of Hestia pictures on Danbooru was in the double digits, with posts as old as 8 months, and now it's in the thousands. I have never seen a character make such a meteoric rise in popularity.
She'll just be replaced by Freya, is all. I just want more art of my darling Hephaestus...
I actually really doubt she'll be replaced by Freya. Promiscuous characters like Freya imo don't usually get as large a fan base as other character types.
