>>102444323 Probably the same reason Kiara finally was allowed to collab with Pomu and Selen could meet Mumei, Ame, Ollie, and Zeta.
Nijisanji was the one blocking them, so they just let Mori and Nerissa through since they desperately needed some clout.
They can't stop them from hanging out, though.
>>102424827They're good friends, but they're not besties or anything. Also, Mumei's an extremely private person, even more than Selen/Doki. Nobody knows who she met or what she's doing offline unless they mention it first. It's pretty likely she just didn't want to deal with drama or anything.
What you SHOULD have brought up instead is Ollie. Ollie mentioned Doki once on stream when she saw her shinkansen 0 cameo and how much of a fan she was (something she did even to Selen), followed her on twitter, and then not a peep since. It's likely she was told not to talk about Doki on main anymore and she followed Doki as an act of protest or something. She's the only female hololive talent to follow Doki that hasn't announced graduation before doing it.
