There's a thing called being friendly and being friends.
You can be both, you can be either exclusively.
None of the 3 are inherently bad in the end. We're here to be entertained and have fun. They provide this and then some.
Many of them are good work friends, but there are a good few who are legit friends IRL, but not the ones you'd think (which are typically ones that bounce off each other well in streams who typically aren't friends IRL, besides a couple like Flare and Noel, and Pekora and Miko, unless you believe dumb shitposts)
A lot of people were surprised at Rushia hanging out at Coco and Kanatas place, for example.
It is very hard to say with EN, besides Kiara and Calli who we know interacted IRL several times and had fun. Whether they'd consider themselves friends or good colleagues is another question, most likely the latter.
>>5867473Luna is pretty much only friends with Aki and Roboco. Has been for a while. (since she played with them back when in Nijisanji as well)
It is, hilariously enough, how I found both Roboco and Akis personal accounts.
