>>75556490the biggest tl;dr is she's still bitter because of how people ghosted her after the termination notice. She tried really hard to fit in with Niji and keep her head down, but they turned on her anyways.
As far as the actual organs goes, she had some insights into finana, kotoka, and hex.
Finana was someone she was very close to and met up with in person predebut, etc. After the termination, sayu and finana got into DMs and talked everything out about what happened, though stupidly, she forgot to keep receipts of that conversation... Then a few days later Finana had her whole "ZAION GASLIGHTED ME" which basically pretended that the conversation they had never even existed, completely flooring sayu when she heard about it.
Kotoka was someone sayu was very, very close to to the point of being actual besties. Her betrayal hurt so badly that she never actually watched Kotoka's video before today, only heard about the context from transcripts or people talking about it. She was really choked up and tried to even cover for some of the sections by saying she was ESL, but she still couldn't get away from just how mean and obviously bullshit the things she was saying were and how they painted Zaion like some kind of selfish monster that couldn't be reasoned with who intentionally hurt Kotoka's "friends."
Hex is a piece of shit, and Zaion had no idea about his SA story prior to making those jokes. She would've avoided that kind of humor had she known, but Hex's words in particular were obviously weaponized. There's no way his words weren't chosen specifically for this though, as Hex and Zaion talked quite a lot about content creation, and he knew the weight of words like that and how they could hurt somebody's career.
