Why Did the Dodgers have an "anime night"?

If you are unaware Vtubers are streamers which use facial tracking software rigged onto a 3D anime style model. They kinda just sit there and play video games but also use anime mannerisms and speech patterns which is what makes them popular. It's essentially the closest thing to an anime character coming to life. Singing is also a part of the job description and many of the top performers have tens of millions of views on their songs and I think they performed some here. Hololive is the largest talent agency for Vtubers and they were the company behind this event.
