This post will be long winded but I can explain why I like her.
>Good taste in vydiaShe doesnt play the usual game of the week stuff, she doesn't play minecraft or apex and she's rather passionate about whatever she does play, she doesnt just slam her head against the game, she tries to see how it works and picks it apart to get good at it.
>Dotes and cares for everyoneI've yet to hear of a single Niji member that didn't say that Nina helped them with something or asked them how they where doing when it seems they where troubled.
>Giga autismDuring a sponsored collab for Princess connect, her and one of her wavemates spend 2 hours just fucking around with the furniture stuff, when it came time to pull, the other girl was like "OH SHES SO CUTE" at the units being pulled and Nina was all "Yea this unit is really good for a one star healer, people sleep a lot on this 2 star tank but she'll get you far), cause she actually does play the game offline, it was a funny moment and pretty uncommon among female vtubers.
She has genuine experience in the entertainment industry and brings a different level of entertainment and experience to the branch, she's a superb host, a pro at keeping conversations going without being abrasive about it.
And finally, I love her laugh, its like a witch's cackle, here's one of my favorite clips of her when you really hear it.
