What? Suisei has absolutely no power as an indie at the time, let alone having the upper advantage in negotiation when she herself basically begged to join Cover. Cover rejected her because she was adamant to keep Suisei character, even selling herself as Cinderella success story. The only reason she even get to keep her character was because of INNK deal, which was its own separate division. Then shit happens during her INNK venture and she was about to quit until A-chan and YAGOO took pity and transferred her to Hololive since they saw she was getting closer to Hololive girls and done way more streaming than Azki.
To say "she negotiated from a position of power" would be belittling her past struggles to get where she is.
