>>25596003I think it has to do with the type of streamers holo tends to hire. Nijisanji hires people who are sociable and have good chemistry, while holo usually hires people who tend to be introverted and reserved.
I hope this doesn't sound too wierd, but females tend to gravitate to things that are more social, and thats why female viewers perfer to watch Nijimen than Stars. Nijisanji has a lot of male streamers that extroverted and they do tons of collabs.
