The Memes

Yes seriously, Memes can sorta define trends as well.
On the massive bunch of +2080 Pixiv fanarts ongoing since 9 days I bet 60% of them are because artists wanted to have fun with this "praise game". The rest is indeed, due to the success from Hestia's chara design which is godlike (kek) cough…. Loli? Check.
Oppai? Check.
Bare armpits? Check.
Bare feet? Check.
Tan girl? Check.
Genki? Check.
Sweet ant cute? Check.
Twintails? Check.
Ribbon(s)? Check.
Reaction Faces factory? Check.
Quite original outfit which emphasize (especially the blue ribbon powering her cleavage) all the above? Check again.

Hestia is truly the embodiement of all these fetishes, thus a veritable miracle of Character creation.

But all that hype becomes very tiring right now…

I think the show is fine but I cannot for all that is holy figure out why Hestia exploded in popularity. Danbooru has 1000 images on her on the first week.
