>>109395512tl;dr is that pretty much all of her "drama" was her desperately trying to get people to at least listen to her side of the story, because the entire indie vtubing community including many of her "close friends" either ghosted or turned on her after the niji thing. (picrel) She was a bit of a social butterfly so cutting off her connections + the constant harassment and doxxing fucked her head, which ended up with her melting down or fucking up and saying something she shouldn't have several times.
Sadly it's now been so long that she's an uncomfortable topic even after the selen thing "vindicated her" that nobody wants to bring her up or even apologize.
The whole thing soured me hard on the larger twitchtuber community. Bunch of fair-weather snakes.
You can tell it's a sister though because Sayu's been quiet in her own little corner of the internet building a new friend group and has been pretty drama free for the past year or so. Sisters love punching down at her whenever they're upset about something, so when sayuposting goes up, something's going down at Niji.
