Persona 4: Dance All Night Artbook

The Persona 4 dance all night has a visual book which includes all of everyone’s favorites such as 

Costume sketches  and

Emo Kanji (Kemoji?) apparently (I can’t stop laughing he looks right out of Daria tv show)...

The return of commentary about each character and even Dojima’s invited to the party. But something that I find super interesting is near the end, and it seems to be a height chart but just for the animation part:

With Dojima and Nanako as placeholders and Nanako listed as 10cm less than when she was in P4 (??), the interesting part is that everyone else but Yu seems to have grown a little. In the rest of the artbook profiles they are not this height.  Which probably means it is not canon, but you’d think that everyone’s getting older and growing but holy shit Kanji broke Eikichi’s tallest persona character record. Yosuke is set closer to Yu in height and apparently Naoto is not the smallest anymore? But there’s a question mark near her height. 

It might be the shoes (it’s definitely the shoes). The question is why did they make this?

Edit: See for profiles Kanji is not listed as 188cm:

So I don’t really know what that thing is supposed to be. (Someone was drunk okay no)
