>>88076318She could well be trying to do ""based"" things like the one in the op to get attention and make people at least interested in her, even if they're not going to watch her on account of her being in Niji. By keeping it up and having it very organically and naturally spread on forums and social media she can keep the attention train going and remind people that she exists. The plan is that when she graduates after a year or whenever the contract is up those people will check her out in her new persona and hopefully stick around to give her a running start as an indie.
If it works it's a pretty good plan. Use the black company to advertise yourself and do things that the company fanbase dislikes, graduate asap, redebut as an indie and have all the people who hate the black company come check you out and hopefully get a fanbase that's relatively sane compared to the sisters.
