So, I like to make Kiku 5'3.5" so I was looking at the heights, and Elizabeta's 5'3" so Kiku's actually taller than someone on the Axis. Anyway, so Gil's 5'9" and Lud's 5'11". Which means there's only a two inch difference between them...

I could only find a gif they compared their height... But... DOES THAT LOOK LIKE TWO INCHES TO YOU?! GIL ONLY COMES UP TO HIS FREAKING CHEST!!
