At the age question, 9S' expression immediately sours. Age had never been a problem back home, but after the ribbing he got because he's the youngest in the Carnival, he's more than a little touchy about it.

"Why is age so important? It's not like I'm biological and go through a period where I need to cared for by adults. I'm fully functional from the moment I'm alive."

Can't he be judged on his deeds?? If he knew that people would respect him less because of his age, he would've lied about it during that public poll!
