>>6124058She had 1m subs before anyone on hololive could dream about that.
She has experience with vtubing, very deep meme pockets, knows when to joke about something and when not. She carefully chooses games that allow her to constantly chit-chat with her viewers, keeping them engaged. If she feels a game is too engaging or doesn't allow her to talk enough to chat, she'll just drop the game.
She knows when to make pervy comments to bait her audience, while also pretending to be oblivious, unlike vshojo, who constantly have to talk about cum, shitting and vaginal blood clots.
She knows to not officially engage with irl youtubers and not to simp over them, which means that her more oblivious audience will feel more attached to her.
She's a clever entrepreneur and entertainer, that's all.
