a V-tuber is a streamer [mainly on twitch] or youtuber that uses a virtual avatar to represent themself. They generally commission 3-D artists to create rigged models and use software to connect the rigs to their movements. V-tuber is meant to be "Virtual Youtuber" There are also PNG-tubers, which are similar but instead of fully rigged 3-D models they simply use images that generally change whenever they say something.
