Re the Tenma/Pippa/PC "political" stuff, as far as PC being toxic to work with due to Pippa's shenanigans, let's make a list of agencies whose talent Pippa has collabed with on stream (so not counting Twitter interactions or that sort of thing):
- Tsunderia
- Idol Corp
- Cyberlive (pre-collapse)
- Kawaii
I'm probably forgetting one or two (Prism? Did she work with someone from Uwu pre-collapse?). Now I'm sure there are some corpos that have blacklisted her behind-the-scenes, but there's still plenty of others who don't seem to have a problem with her enough that she doesn't seem to be suffering for lack of collab opportunities.
So what's the difference with Tenma? Well, she has mostly collabed with fleshtubers, right? That might be the difference if these people she's trying to work with and being turned down by are fleshtubers. Those people operate in an entirely different sphere than these anime girls and, by virtue of both not playing a character and by showing their actual face, have to give more consideration to protecting their image, both metaphorically and literally. It's sad, but I don't necessarily blame them; they are in Rome and must do as the Romans do. And I presume Tenma would have just as many collab opportunities with other agency vtubers just as Pippa has had if she wanted that, but maybe that's not what she wants. Maybe she's not as in love with the hobby as Pippa is despite it being her job.
So it's a sad situation and I hope she finds a way to find happiness despite the toxic political environment in Western society limiting her options, but at the same time I can't really blame anyone in particular for this situation.
