Nazuna started out very optimistic and hopeful, she had fun in her streams and was reaching out to communicate with a bunch of random vtubers. She seemed to be enjoying herself. Then a couple months pass, which means she got a few Twitch payouts. Then she has her first menhera rant. What was the only real fact brought up in that rant? She wasn't making as much money as she wanted to. She was expecting to make Rushia money but Twitch just doesn't have that high donation culture that Hololive streamers on YT have. But that's a whole different story. This was also before Vshojo was producing Nazuna goods so she wasn't getting merch money from them as well. And from then the menhera spiral started. More often than not Nazuna was in a shitty mood, depressed, not feeling like streaming, she started isolating herself, cancelling streams, etc.
But the eye opening thing? During that same period she's active on Mike without problems. Every day doing Twitcasts, and she is noticeably happier during them every time. Her fans are always making note of it, both here and in the JP communities. There were several occasions where she did a Nazuna stream, was pissed off, then did a Twitcast and her mood turns around and she ends it happy as a clam. So what's the difference? Her Twitcasts have a constant stream of donations. Same story with Mike's rare Youtube streams. She's always happy during them. She's also constantly getting superchats. When you notice this pattern you can't unsee it. Now go watch some Nazuna streams. She often starts out pretty upbeat. Coincidentally, the beginning of Twitch streams is usually when the most people are sending their resub messages, subbing, giving gift subs and throwing some bits. Then when that stops she's mad.
If she actually starts consistently streaming on Mike you'll see this same pattern in a few months. She's gonna lose her scarcity buff and the SCs will dwindle and that happy mood she had last night will be gone. It's all about money with her.
