Is there any statement from any ex-niji liver that even mentions issues with other livers?

I don't remember Mysta, Nina, Pomu, Yugo or even Zaion saying that they suffered from anything but having terrible incompetent management. In Zaion's history she even said that she was supported by the other livers but was screwed by management over and over.
She was thrown under the bus by some talents after she was fired but it's more consistent to management being atrocious than with livers being bullies.

Sure, some livers are awful, but I truly can't find any testimony that supports the Liver to Liver bullying theory.
