>>75397294A real answer? After NijiEN goes under in a month or two, probably, unless she decides to collab on a PL. Just like how everybody and their mother were able to attend OffKai once Niji got out of the picture, Holo needs Niji to fucking off itself in order to keep them from throw hissy fits.
Though I'm wondering why you're focusing so much on "collab" though. They were barely able to collab when she was in Niji, as is, and now both of them are busier than ever.
