For newfags to Kiki's stream who weren't here for the first week of her debut and don't know what this Annie shit is about, basically he's an artist and a groomer who makes art for vtubers in exchange for being added on twitter. He outright asks to be added in exchange for the art, if you were to go far enough back in /pyon/ threads you'd find his posts where he asked to be added if he made her art.
Once she did add him, he started bragging in the theads about how Kiki followed him on twitter and how he DMed her in private, I guess trying to goad over and taunt other champyons? Well he has a history of doing this with just about every /here/tuber, and some DMs ended up getting linked, I believe it was Nade? Can't remember 100% which vtuber it was, but he DMed her and was basically trying to stir up drama between her and Kiki, while also trying to convince her to collab with Kiki. The DMs got posted in one of Nade(?)'s threads, people started to tell Kiki about Annie in response, Annie had a meltdown about champyons bringing up his old drama, something happened in the background and Kiki ended up blocking him on twitter, banned him from her streams and ended up removing every person she followed excepting fellow vtubers, all as a result of his shit. He still shows up in threads every now and again and blames champyons for "forcing" her to close DMs, suggesting that she'd be happier if she'd never banned him. Kiki has mentioned him in her streams a few times, but never by name. She mentions a groomer in her DMs she had to expel. That's Annie.
If you see someone in these threads dismissing criticism of Annie, sticking up for him, or blaming champyons for manipulating Kiki into closing her DMs, that's Annie. Kiki herself refers to him as "the groomer". Thank you for coming to my ted talk.
