Is it? I feel there's a much bigger tendency for westerners to show their mug and speak while Japanese prefer to hide (both mug and voice) if at all possible.

Yeah, definitely. There's a self selection bias where a person who wants to stream is going to tend to be a person who wants to show their face. But it is not weird / frowned upon if there is no face and the content itself (gaming, coding, whatever) is the entire screen. I think most normies would much prefer no face to an anime character.

I do think it would be weird to hide your voice, though.

For once, I'd like to see a VTuber presented as classic Warner Brothers characters. Let's see Porky Pig present this stuff.

(Anyway, the work itself is great!)

More likely it'll be a character like Dot. Or Bugs Bunny in a dress.

I would love to do a tech vtube as Slappy Squirrel.
