> Anime girl youtubers.....for what purpose exactly? It may have a phase of boosting that trend but for what? Why does that option offer onto the table?

Oh weebs... well, not even 4chan likes anime that much despite its influence but I am sure it could perfectly take up a third of the site. 
I feel she is a step above that. Maybe not in quality but in notability. 4chan personified as an anime girl will be hitting on several things at once. She'll get a lot of attention because she's from 4chan. There is a lot of people who still see 4chan as the cool edgy meme place and she'll probably inherent some of that idolization. Then there be the mainstream "Otakus", who will be viewing her because anime girl. Next up is commentary community and others who will jump onto her because it's both 4chan (edgy clickbait/sexy anime girl clickbait) and that it's trending. Maybe I'm thinking too far ahead and too certain but I feel like a halfway competent marketing effort plus hitting the right memes plus it'll be 4chan  or should I say 4channel  interacting with YT directly it could be a big deal for many people.   

First it'll be the audiences of people like this:

Who idealize/respect 4chan. In the days of old these be the type of people who'd fill /b/'s early ranks and than filter out. 

Then this guy. This type of neo-mainstream-anime people.

Though he won't make videos on 4chan himself. This group I see as another large demo that could flock to her. There not the same group as the tweens and memers but they're cousins. They like a little edge and they are the ones who stayed around things like yandere simulator and doki doki the longest. 

Then this. General commentary and consumption:

Which would hop onto it once the other two gave it traction. 

Don't bother watching all those vids. It ain't worth it. Watching a little and maybe peeking though the comments gives ya the idea.  the last video I linked though, at least skip to near the front...  

This is the TS rip. Now spinning as a globe!
