How old do they look?

...Under a year? Since they can't seem to stand

Uuu... Rin was already 14 years old at birth so Rin totally can't get used to this body.

That's right. Since Vocaloids don't age like humans do.

2007.12.27 Congratulations on your release!

(14 years old)

2107.12.27 Happy 100th anniversary!

(14 years old)

It's only natural that we have no experience with an infant stage

But for us, you were like babies the first time you got installed in the PC!

That's right

Eh? What do you mean?

You were curious about so many things

Even when you stumbled and fell, you stood right back up and took on the next challenge

Even though you looked 14, inside you were like babies learning about the world
