Is it just me, or does anyone else think Maya is getting progressively taller throughout the volumes?

(ah I love tall guys)

I hadn't really thought about his height but he is definitely maturing physically; his face looks more "grown up." So it stands to reason that he is taller too. That's one of the things that I really love about this series: that the characters are growing and maturing mentally/emotionally AND are also actually 'growing up' physically.
