What's stopping them from collabing with Holostars at this point? I get that Pekora still has to pretend to be asocial to not lose her delusional fans and that Noel is obviously a man hating lesbian. But what's Marine and Flare's reason for acting like they don't exist at all? I remember that one time a ichimin was asking her to include Holostars in her seiyuu audition for her game and she switched topics as quick as possible.
Like seriously what are you afraid of? Most of your fans would be ok if you collabed with Holostars just like when you collabed with other males before.
I'm glad Rushia showed how disingenuous sankisei is.
