>I don't think her model really debuffed her much, she had great growth, especially for an ID in the past.
That's absolutely true but there is an underlying context: she debuted midway through the peak western interest in this anime right here
>Zombieland saga
right at the eve of their second season.
Back then there was a MASSIVE interest for "idol zombies" and had she played her role straight she could have make it work.
But, as you say, she was too crass and that helped to sink her live audience

My main point would be Ollie not only adopting Olivia's design but also the expected image that she CORRECTLY imputed on Olivia: an agreeable, positive and beautiful live streamer.
