Years after they decided to go out into the world, David 117 and his friends, old and new; return once more for a priority mission that's out of their world; quite literally. Under peace time conditions, the amborgs have been deemed obsolete and unnecessary but when a ghost from the past arrives at their doorstep, they are the only ones qualified to prepare for the cataclysm approaching their unsuspecting planet. For the survival of humanity, the amborgs go to space to prepare the approaching threat. The universes are forever changed as they are joined by a defense fleet of the S.C.E. from their next-door universe to fight against a mysterious alien species preparing a deadly conquest. Will the combined effort of two universes and the cooperation between this alliance be enough to turn the tide of this sudden conflict in their favor? Will the amborgs learn about what the alternate universe has to provide? Impossible odds and a very unlikely chance of success. It's just another typical day for an amborg.
