They have flashy personalities that keep my attention.

I find that the only vtubers I can bear to watch are those who have an exaggerated personality.
They have to sound and act like anime characters.

Most other Holos, even popular ones like Koyori, are boring to me, because they behave exactly how I'd imagine your average female streamer would behave.
