iirc Rushia has no off collabs on her own channel, unless the one she nuked the vod by showing nails on camera, was on hers. I can't really remember anyone talking about meeting with her off-stream, even if not streaming, either. She also had some bs excuses, like getting a cold a day before her genmates would gather together for a sleepover. It does tell quite a lot if your supposed coworker refuses to meet you irl, when everyone else has no problem doing so. Even Aqua and Pekora would go out to cafe with others
