Hmm.. this image looks a lot lighter than the original manga.

Anyway back to the topic, I think Nanaba is female. In the lastest chapter of the spin off: Attack on titan junior high Nabana had this conversation with Mike. She blushed when Mike complimented her so I suppose it could be a hint that she had a thing for Mike in the spin off. It was written by Isayama so it couldn't be wrong. Unless it was common for a guy to blush when they are complimented by another guy.

Lol i keep typing Nabana as Banana
