Besides Riro, it seemed like the company could only keep their girls in check as long as they had money. It's really not great when E-Sekai, their first gen, had ticking time bombs and they hired badly and didn't fix their hiring well enough until they hired for Gen 2. I feel sorry the most for Encore, their most recent invades gen, because they got hired and then things immediately started going south with Idol.
