>>7791453i get what you're saying but you learn quite a bit about your coworkers in many jobs. it's not a completely false face, it's just an unnatural one brought about by circumstance.
I think that's the key difference, one idea is of them purposefully changing their face with effort, and the other is them changing their face passively, not with too much effort but rather by immersion, in response to the pressures and realities of their surroundings.
v-tubers really do both but the meaningful stuff lies on the latter. they memorize and lie about who they physically are, as in a dragon or squid, and where they come from, such as the underworld, but the meaningful stuff, like how they react to people, is vastly of the latter -- that sort of in-between of effort and non effort. how one feels when they are immersed in a game or character they play.
i say all this to get across a thing i want to leave as an understanding of why and how this culture operates as it does; that the character really takes over the v-tuber in many cases. like actors who get engrossed in their character -- but the key difference being v-tuber models and personalities are built from the ground up to synergize with the roommates. everything from their hair, clothing, expressions, personality, even their content, is made to be like a mold or gel gently encompassing them so that they may gradually and convincingly twist themselves into their character.
this of course isn't true for all, but rather for the best. their character becomes an identity entwined with they themselves.
