Olivia is basically white girl becomes vtuber, she was raised as a very standard californian girl, doing classes in ballet, flower arrangement and any other activity you could see in a Reese Witherspoon movie.
She rose a community on the sole basis of being extroverted, optimistic and amusingly stereotyped, in a way she can maintain kayfabe better than 90% of other cthulu'esque avatars because she feels like an alien in the v-tuber scene. Got corrupted a bit by others, but not enough to change her content.
