Unless Azuma is uncredited for chara design on Magical project S (which would be awesome), I really don't see why this has him as the artist.

however, since janitor changed it, i'm hesitant to do anything else.

Being a janitor doesn't necessarily mean they're always correct. They are mortal, they can be killed! (Please refrain from killing the janitors).

You can always state your reasoning for making the change in the comments (don't have to bump the post) and then make the change.

It is especially not my place to make that assumption though.

and just as well; apparently azuma *did* do some character art, although the only bit of evidence on here is the Sasami comic.

This illustration is from the Azumanga: Digitally Remastered Edition artbook.
