>>317710It's the original Ai-chan. She basically face revealed and called out her old management for being stupid fucks and now basically runs the Kizuna Ai project (as a "creative adviser" or something). The extra Ais went off and got themselves new designs and a new channel as Love-chan and Aipii, but Aipii graduated so now it's just Love-chan.
(Ai China is amazingly still chugging along. No idea if it's any popular though.)
