Not related to Nijisanji, but Amelia Watson is running her animal charity benefit stream today. It reflects well on vtubers as a whole, so if you are interested in that kind of thing it might be worth a few dollars. They seem to be doing fairly well as of the time of this post, at $22k already.
Charity donation page is here:
