Okay, Hololive debuts done
Shiori is sorta the opposite of what you'd expect from the agency: Edgy, openly menhera, pretty straight, and much more into the sort of things you'd expect from a tumblr denizen than a vtuber. Also seems like she's aiming to be a GFE streamer?
Bijou, on the other hand, is sort the crystallization of Hololive: Singer/gamer/comedian gremlin who also enjoys flirting with girls. She is great and I expect her to be the next big hit
Nerissa is a fantastic singer. And a cool and calm onee-san as a streamer. Personally I'm hoping the dorky side we see in her xeets shows up more on-stream
FuwaMoco are very precious. Also I think they're dating IRL
