Battle in the Floating City (Kuuchuu Toshi no Tatakai) is a manga set between episodes 22 and 23 (73 and 74 of the series whole) of Blue Dragon's second season. Going off of Japanese Wikipedia, I wanna say it was written by the series composition writer, Akatsuki Yamatoya, and drawn by Noriko Otake, who was an animation director for the first season. I'm guessing if Yamatoya didn't write this himself, then he provided notes for Otake to work from. Another source lists Otake as "author" and Yamatoya as "original author", but do they say "original author" because he came up with this story, or is he credited that way because he he wrote the anime this is based on? Both? I dunno.
I thought about going through and cleaning this, but I have no real experience in the area, especially with physically scanned materials. I attempted doing a quick, kinda half-assed cleaning job and releasing that alongside the untampered raws, but I didn't see the point. It was a bit of fun trying, though. Here's some examples of my attempts.
The manga looks fun. Even though it's untranslated, I feel like you should still be able to get the gist of what's going on. In any case, links are below.
