one of their vTuber idols, becoming effectively the Chief Operations Officer of the branch despite just being a female model, and the whole office going matriarchal politics.

I'm not sure if Elira runs anything, but she was the one who hosted the 'black stream' that happened after the termination of Selen Tatsuki, now Dokibird where they revealed (or the higher ups told them to reveal) some information that was actually confidential and Dokibird's lawyer agreed to not speak on it, in that the hospitalization was for a suicide attempt and that that suicide attempt was her second attempt, and both attempts were a result of bullying from within Nijisanji.

Overall, the company barely supports its talents, the EN branch has talents graduating left and right and will probably be merged with the main branch within a year, and overall fucking sucks.
