It's been assumed one of the Invaders is moon jelly (aka Manaka Umio, formerly of the same MyHoloTV gen as Bae and Miori) for a while now, and that's likely her with a new model. The 'Awawawa' thing is kind of her catch phrase, she's close to a few girls in Phase, and even recently acquired a Mahjong Soul addiction. The 'homeless' location tag on that new account is also amusing because she just got kicked out of her apartment last week.
The real question is that if it is her, why bother making a new account? It makes sense for Urara/Dizzy, but she doesn't have the same kind of baggage. Maybe her contract is set up in a way where she can freely reference her PL activities, but will run new accounts so just in case things did fall over she wouldn't lose absolutely everything like Yuri did?
At any rate it really makes this feel more like a 'proper gen' and not what was expected from an Invaders wave.
