>>68962005From what I know about Tsunderia is that it was a shitshow and one of the talents (Urara/Slugma) had to essentially work as a manager for all the other girls. So when Rosemi's PL got accepted into Niji Slugma told her to go there because it was, at the time, way better than Tsunderia.
Fags here will call Rosemi a rat or whatever but I haven't heard any ex-Tsunderia member talk shit about her or what she did.
