The GMG uses the Blood Dragons, this is a result from post war written in wiki....
The eighth century would also mark a period of increasingly difficult relations between the Guild and Samura Industries, who not only would stoically accept the Kusari government's war reparation tax put on the Guild after the defeat of the Rheinlanders, but would be trying to push down the H-Fuel price even further so as to finance their own gas mining project in Hokkaido. Convinced that Samura is abusing and exploiting their agreement, the GMG would finally agree to secretly finance Blood Dragon operations in Hokkaido, in order to stop the H-Fuel mining project there. To further aid the Dragons in their engagement, GMG veteran fighter pilots would pass on their experience in nebula engagements to the revolutionaries. This would allow Dragon fighters to turn circles around the Kusari Navy in both Hokkaido and Honshu, and conduct strikes with more precision and destructiveness than ever. Funding for the Dragon separatists would set the Samura project off schedule for years to come, and would make mining H-Fuel in Hokkaido far more expensive than the costs incurred by the GMG.
