>>27060321Kiara is a narcissist so she has to be in the spotlight. Sometimes that means putting down her genmates in minor ways, other times it's making a spectacle of herself so she stands out above the others (sometimes at the expense of others).
I like Kiara type personalities but they can be difficult to be with sometimes. You have to literally mog these types of people so they come to see you as their equal or worthy of respect, in their eyes. Thankfully, them being in Hololive serves as a sort of equalizer but you still see it leak through in instances of "bitchiness" as you describe.
