>Elira is an evil bitch and bullied Selen to the point of suicide
>Elira is a victim of Anycolor and she didn't want to make the Black Frame Stream
I think the truth is somewhere in the middle. From what we know thanks to Raziel's leaks, there's no real management in NijiEN and Elira had to step up early on to assume the role of shadow management, and it's easy to imagine how grateful Anycolor was with her for doing that, seeing the ridiculous amount of favoritism she always got compared to Pomu.
My guess is that she didn't have any real control about who got the merch and collabs opportunities, but the JP management actually listened to her when she spoke favorably about someone, because they trusted on her opinion.
I'm sure she wasn't oblivious about how much power she had in the branch, but she knew she was in a good spot and there wasn't any real reason to give up her position as the shadow manager, so she kept playing her part. She didn't have to do much anyway, just organize meetings and probably just act as a translator when the JP branch wanted to talk with some of the organs. Everyone was happy, they were getting a lot of money and the community loved Nijisanji.
And then everything changed. A few talents started going out together, drama happened, Vox and Reimu got the crazy chinese fans mad, Finana couldn't shut the fuck up, Aster harassed a few of the organs, Zaion was terminated, Selen kept complaining on twitter, Millie made the secret discord server stream, the AR was cancelled and some of the talents started realizing that their careers had hit a dead end and that Nijisanji wasn't interesting in investing on them.
Elira's easy management job suddenly turned into a nightmare. I imagine she tried to be useful and actually help at first, but she couldn't fix anything because she didn't have any real management powers and the JP branch didn't care about was happening, so she was completely useless and eventually just gave up. This was around the time when Enna leaked that JP management wasn't happy with their numbers, so most of the organs were particularly on edge and just wanted to look out for themselves, and that's the moment when the clique adopted her final form: a highschool clique.
The talents outside the hanamori clique were isolated, and every transgression against the company was treated like a personal attack to the group of the popular kids.
The Black Frame stream was just the result of Elira assuming like a retard an impossible job because it looked like easy money at first, and Niji JP being a sweatshop that couldn't care less about the talents.
Elira is an adult and she helds part of the responsibility of everything that happened, but framing her as the evil mastermind that bullied Selen and ruined Riku's "apology" is precisely what Anycolor wants. She is a selfish retard and should have quit the moment they asked her to backstab Selen, but Riku is the real villain here.
Vox and Hex are malicious cunts btw.
