>>1915595While I agree with the ego merge part, I still think some of them have a pretty good margin between their normal selves and what they do to be a content creator.
Luna especially, you can hear her drop character when she gets genuinely frustrated at haachama's cooking one time.
However, I'm saying that it's a demonstration of acting ability to distance yourself from a character you regularly play as, and that it's actually really damn impressive as someone who's done acting before to see someone not merge themselves with whatever character they put on.
Ignoring the argument of whether it's good to play a character instead of showing your true self, I'd say Pekora, Luna and Mori are the best at keeping up a character and/or voice that's different to their normal self, whether or not it's they drop it frequently.
