/vt/ gave her shit for years, but by now it's been undeniably proven that Kiara actually understands and respects Japanese culture in general and idol culture in particular, she moved to Japan, learned the language and tried to fit in while she was there, as well as respecting her normal and gachikoi fans.
Calli*pe M*ri however is the former unpopular kid who disliked her otaku friends and started spitting in the hand that feed her as soon as some of the popular kids started giving her attention. She has no respect for Japan and looks down on idol culture, hasn't learned the language yet and only hangs around in Gaijin majority places where the only japanese people she has to interact with are cashiers honor bound to treat her as a superior and dogeza whenever she throws a tantrum. What she wants is to be an ironic womanchild eceleb who does nothing but stroke her own ego all day, not a diligent idol and team player who at least tries not to make her genmates' lives harder. The crowd she craves validation from looks down on vtubing, idols and japanese culture, and she at the same time thinks she's superior to her fellow vtubers and a strong woman who don't need no yagoo, but at the same time deep down she feels shame for not being able to put her money where her mind's mouth is and actually do it alone, so the only way she has to cope is to constantly seethe internally and sometimes lash out at the fans who give her money not for what she wants to be, but for what she ought to be, an idol.
