I forget how similar to us the nips are some aspects lol, the obsession with PLs and insane standards and reasons for disliking new talent are all the same no matter where you go, though these opinions are obviously a fringe of dramamongers like us, most nips probably don't care.From the little I read in skkr, the JP side are more positive towards the former indies as they seem to understand the essence of Vtubing and the struggles of being one (also relates to the Cinderella story of an indie joining corpo and rising up in success).
They're not really fans of "fallen idols" and "fleshstreamer who is already popular" who they consider use the company for clout.
FWIW the current Flow Glow popularity from most popular to least is Chihaya, Su, Vivi, Nico, Riona.
