Very high probability this thread was made as a falseflag by /pyon/ groomers, so they can show it to Kiki and then comfort/emotionally manipulate her and furthur isolate her from friends and support networks that could detect the grooming and warn her about it, by using as a scapegoat anyone they feel threatened by.
Genuine warning especially to indie vtubers: Take note of her regular chatters and those who interact with her heavily on Twitter. Several of them are prolific groomers who have a long history of attempting to groom women online, and vtubing is just the newest hunting ground for them.
