Its only conjecture, but there was a years old tweet (2020) by Mugi Ienaga, a Niji oldfag, about feeling sick after visiting YAB's studio. The tweet was up for years until a day or two after the scandal broke.
It was confirmed that she had visited YAB by the man himself, the tweet is still up
Now, it could have been a geniune sickness and not foul play. But the speed at which the tweets got deleted is somewhat strange
The scorned earth behavior is what icks people, but it's understandable.
You cannot assume the worse from the start as well, vtubers are sick all the time and there's no mind-readers in Niji staff, but I agree completely that talents should never go by themselves when doing something for the company, considering said project (in this case, music) is owned by the company, it's their responsibility to oversee it.
What boggles me is that he got an extensive list of victims and the girls never talked between themselves about it? If they did, brought up to management and nothing was done about it, then @Limkin will be correct.
