Obviously, Cover is a Japanese company and the vast majority of the talents are Japanese. Kiara knew this when she signed on with the company and then failed to obtain a business visa to stay in the country. Rather than taking steps to ensure she would have every advantage, she actually took steps to distance herself from her core fanbase, the company itself and continues to this day to complain about it every chance she gets. Her hole is self-dug.
In comparison, most of the JP talents have taken steps to move closer to the main office, for example Shion and Rushia (may she not be forgotten) both moved from the countryside into Tokyo. Many of the other members have made huge strives to improve their idol activities. It wasn't that long ago when we laughed at how terrible of a singer Choco was and now she sounds polished.
Kiara's problem is that she continues to wallow in self-pity. Her stream this morning was a bitch fest about how the band was awful, the song SHE chose was a poor choice for the event and other perceived slights. She was also on stream with a Niji talent (Nina Kosaka) this morning and complained about how terrible she looked in the stream rather than introducing herself and getting over it.
If you look at the bird app, you can see that every other talent has posted nothing but positive takes on their appearance. The others take self-responsibility and admit to their own faults. But Kiara, she blames anyone but herself. Again.
It is quite fun to watch her seethe though.
