After Rellia's General Tartha gives mankind a timeline to prepare for war, General Perrara of United States and Professor Makoto of Japan brainstorm a resolution to level the playing field. They create the Shadow Organization with the help of underground intelligence networks and four alien warriors as trainers. Despite being Earth's best kept secret, it becomes a pillar of strength.

But, the inside is rotten, built on prejudice and weak laws towards the hybrid offspring. The alien warriors also appear to have ulterior motives for helping mankind. Perrara and Makoto start to ask themselves if they were more optimistic than realistic in their endeavors.

Will the organization straighten itself out and thrive as a beacon of hope for humanity? Time is not on our side.
