>>26108954roru, even entertaining this bait for a second, it doesn't even make sense.
First of all, Cover doesn't fire people for "underperforming", they prefer to just not rock the boat and will keep anyone forever, no matter their metrics (the only ng is a contract-breaking yab). Second, she still brings in vastly more money for Cover than she costs them in expenses.
Third, if you expand your views beyond just comparing her to her HoloEN mates (who all have also plateaued or reclined in growth and view metrics, it's not just a Kiara thing but you don't mention that for bait) the Hololive gig even with her numbers on the lower end of HoloEN puts her still in the 0.01% echelon of vtubers or streamers in general. She is under no hurry to leave the job that still pays her the most monthly income she will ever see in her life, and is under no illusion that she would do any better by graduating (what for? boohoo, I don't do as well as a few other people in my company, but I'm still doing better than thousands of people out there. She's grown to be less noomberbrained than her antis who always attacked her with it) and going solo indie for nothing.
She will ride out this gig for all its worth, and maybe in a few years down the line when she has amassed enough money for her cabin-inna-woods dream she will decide she has enough and retire, but until then, you're not going to get rid of her so easily, baitchama.
