Siblings have faces like paper, viewers mistook them as 2D avatar.
Jokes aside, as much I enjoy vtuber slop, I don't feel good about the disclaimer in the beginning. So they will be using the avatar during IRL scene for every character?What with “don't want to destroy the ideal“? Isn't like the selling point is them being fail human?
The same reason I quit watching “I forgot to turn off stream and become legendary“ anime, it's so jarring (and cringe)having perfect looking fantasy avatar during IRL scene.
Also this approach created a big plot hole right from the bat, isn't the human won't register at all if they are using avatar during streaming?So oniichan liftting imouto would just be the paperdoll floating at most, his face won't register at all.
