Probably the same thing they wonder when they see "influencers" car shopping or whatever. Ultimately these are e-celebs who mostly succeed on their looks, even Emiru's curated "dgaf sweatpants" look is meant for this. On the other hand seeing her in regular locations with her cosplay fits and schoolgirl lolita clothes is hilarious. Everybody including her knows she's basically saying "look at my ass, thighs and stomach" with every outfit she wears, but I'm not complaining
