v-tubers are a kind of animated avatar that people use on streaming platforms; places where you're sort of expected to have a webcam showing your reactions, but you don't want to because you're [trans and dysphoric, afraid of openly being a girl on the internet, shy, actually a dragon deep down, some other valid reason, or even an invalid reason because who cares]. They work various ways; some make the avatar try to map to what you're saying, some puppet it from keyboard controls, some try to match it to a webcam's output, whatever.

Hatsune Miku is a rubber band ball made of memes. There was a corporate mascot at some point, but tens of thousands of people have made her mean whatever they want her to mean, building layer after layer of conflicting meanings, until that's all there is. She's just Hatsune Miku.
