Kuzuha is very entertaining when he's bantering with the girls and most people watch him for that reason, I mean sure he can bantz with the guys too but I can't really stand a full males collab stream since I mainly watch vtuber for the cute girls. I'm sure Holostars are not inferior to any Nijimales so they'll shine for sure if entertaining Holomems like PekoMarine give them a chance.
