Like I said, that's a skin issue. The logo isn't there because the skin doesn't have an image for Wit Studio.


What you can do, though, if you have an artistic bent, is make your own!

First grab the logo from e.g. the studio website: http://witstudio.co.jp/
Convert it to a .png file, white-on-clear, sized 161px x 109px.
(This is where the creative skill comes in - check the ones in the skin already to see what you're after.)
Save it as "Wit Studio.png".
Find your Aeon Nox addon folder ("skin.aeon.nox"), go to the "media" sub-folder.
Create a new folder inside it called "flags".
Create a new folder inside that called "studios".
Inside that place the Wit Studio.png.

Et voilà! You should now see that logo show up for Shingeki no Kyojin.

(You'll likely lose it when the skin updates, so be sure to share it back with the creators of the skin so that it can be added permanently.)
