>>11273419Vtuber who made a name for herself by playing mahjong, first on 10hoe and later on Jantama/Mahjong soul. She was THE mahjong vtuber, collabed with a ton of Holos/Nijis/indies in mahjong soul, had her own sponsored program with Tenkai, even had a bunch of M-league pros videochat in to congratulate her on her 3D debut. In particular she was very close to Shigure Ui, Ichinose Uruha, and Tokoyami Towa the latter two of which she formed a unit with called Tokonokise.
Then a databreach happens on note which is a Japanese BBS revealing all posts' IPs. Some people do some snooping and find out that an IP which is extremely likely to be Sio was behind a ton of flame posts on other vtubers (notably Roboco who she called boring). This all blows up in her face and antis basically drive her off streaming.
