Nina has actual legitimate experience in the entertainment industry which she can use to help the other girls, she goes nuts and is mega passionate about the games she enjoys, she is an actual gamer to boot and decent to great at the stuff she does enjoy.
Her zatzus are super comfy, she also manages her non english communities far better than Petra does and she's an endurance streamer to boot.
She's honestly NijiEN's best hire(don't take this as me shitting on the girls, I'm not), they needed someone with the kind of experience in entertaintment that Nina has.
