Kizuna Ai fans might have reason to expect a return in a few months, after her official channels started a countdown. Also called by fans as "Ai-chan", the popular vtuber has been on hiatus since February 26, 2022 (today, vtubers are maybe more a Twitch thing than a YouTube one). Her channel has still been adding some videos from time to time, but the vtuber hasn't appeared since then.
