Kevin Neece photoshop edited The Niflheim Rebellion Saga storyline from the Oh My Goddess manga as a counterbalance to his Bad Goddess fan fiction series, both as an apology for the heavy, insulting, criticizing nature of Bad Goddess, and as a prequel that connects Bad Goddess to Ah My Goddess Flights of Fancy/Fighting Wings. Technically, Kosuke Fujishima and Kodansha Ltd could sue Kevin for making this. The English Scanlations were done off of GMT Goddess Miyaku Team's work. This is the most faithful Fujishima adaptation ever made.
The Niflheim Rebellion Storyline came into existence because Kosuke Fujishima wanted to leave Oh My Goddess behind, and not wanting to lose their cash cow, Kodansha offered him a bonus to keep the series going. Fujishima's solution was to create one big epic serial finale storyline that would take a minimum of four years to release.
Manga panels and dialogue read backwards, from right to left. Kevin reversed the panels in forward left to right motion as it looked too strange for the panels to appear going backwards, but the dialogue itself still reads backwards in manga form. Kevin also photoshopped the issues in backwards order so that if Kodansha were to step in and legally block him from completing the project, everyone would at least have the ending.
In 2011, during the release of the Bonus OAD episodes, some new Oh My Goddess animation videos were made for the Pachinko Machines. One of the videos featured new animation for Marller, Velsper, and Hagall. As all of the other artwork in the videos was made from stock animation, this led the Oh My Goddess internet community to believe that there may have been a third season planned focusing on the Niflheim Rebellion storyline that may have gotten scrapped and the animation footage of Velsper and Hagall was leftover test animation. Velsper was not featured in the Niflheim Rebellion storyline in human form, as he was trapped in the form of Belldandy's Housecat.
There's a shot during the Lake Goddess flashback that implies Keiichi and Belldandy had sex when they were possessing the bodies of the Lake Goddess and her Boyfriend. This is actually misleading. From Belldandy and Keiichi's point of view, they were not sleeping with each other. From their perspective, they were sleeping with the other partner. Belldandy had sex with the Wandering Minstrel, and Keiichi had sex
with the Lake Goddess. In a strange way, you might say they were swinging.
