Neosaka was conceived by Amoki, and written/drawn by Amoki (odd numbered strips) and Tim Mannveille (even) in 2003.
Tim went on to create Devil May Dance, a Space Channel 5 / Devil May Cry doujinshi. You can see his other projects at his site.
If for some reason you want to see the original 2003 Neosaka FAQ and site, you can navigate to it here!
