So I've been doing hours and hours of research on Japanese websites [which I had to sit and translate <_>"]
I've been curious about Levi's age.
The author wanted to keep it a secret, but hahahaha, I found an interview where they give a hint on his age!
Levi is 30+!
I'm 15 and I'm the same height as a 30+-year-old-man.
Not sure if midget.
