I never actually disliked Kiara. If anything, I think that he could be easily on the top 3 of holoEN.
...But she keeps doing dumb mistakes. It's almost as if she tried LESS to be unique and recognizable, she'd actually manage it. By attempting every single tried and true technique that every single chuuba and their mama has done, she manages to not stand out that much. Her voice original criticism might be the thing that stands out more about her and it's easily the one thing that encapsulates everything that's wrong with her: filters most potential viewers and that can be fixed by her NOT doing it, but being a pigheaded as she is, she keeps doing it anyway while ignoring everyone telling her otherwise.
Things are extra unhelpful when her fanbase acts like a cult, filtering anyone not willing to just lick her boots with no question. I sometimes think that all this bootlicking might have gotten to her head somewhat, making her really believe the hype the KFP has built around her. If they weren't as rigid, maybe Kiara would also be more open to the criticism and could actually improve.
If anything, the signs are there. She tries to play off a dynamic despite her ego problems, sticks to the traditional audience grabbing techniques of the early era Vtubing AND respects the scene to the point of making sure the pink cat collab was nothing but an endless, one sided mogging and made it a showcase of which side of the East / West style was superior. She likes what she does and that drives her. Way fucking better than Mori.
>tl;dr
Kiara needs some work, but it's unfair she's bellow the fucking Grim Wigger
