If you want to ask who is my favorite hololive girl? Well... my answer is I don't have any since I can't really decide who is the best.
But in general, all of them are likable.
Matsuri, the girl is also very very precious but not in the same way of others. She is a little bit of pervy but she has a brilliant mind and is cute in her own way. In real life, she would be the best friend you can possibly ever have.
