>>45220413> the Elira cliqueA group of friends centered around Elira that knew each other from way before they joined Nijisanji. The core members are Elira, Enna and Millie (old university friends). It further includes those acquaintances from their Utaite days such as Shu; and of course those who became associated with them after joining NijiEN. There is some contention on whether specific people should be considered part of the clique. Notably, it's sometimes called "Enna's clique" as Elira herself is not that much of a bitch (or at least doesn't act like one).
> why they run NijiEN and bully the non-clique membersThey don't "run" NijiEN. It's more like a high school clique that scoffs at anyone outside of their social circle.
> their involvement when it came to getting rid of Zaion?Clash of personalities, mostly. There's also Kyo shitting on Zaion with his RM account. Plus some schizo rrats about how the clique is safe from disciplinary action by management despite having a history of yabs similar to Zaion.
