>>22291660It's not just Polka, most vtubers are friends with each other. There's a reason the term Nijishojo started recently. If you've ever listened to Niji and Vshojo just shoot the shit for 2 hours after a collab they're all good friends, and a number of them will sometimes pop into Mouse's stream since she now has an open call for anyone that she decided to keep ever since she started that with her subathon. This extends to a number of people from Holo as well, most of them have nothing but good things to say about each other and anytime they collab it's nothing but a fucking love session.
