The Legendary Ghost: Extinction is the direct sequel to The Legendary Ghost: The Ghastly Perfection. The exiled G-Fighters depart from the Earth, knowing they are no longer welcome back there. As they set with a blind hope of redeeming their name and sabotaging the cruel enemies, the people of Earth already accepts the lies spread by the media. But is it really true that everyone bought them? As a few groups of teenagers slowly unite to grow a realization for the coming storm, they only grasp at the bigger conspiracy lying at the heart of humanity. The enemy has the controls, just like they did during the Ghost Invasion, manipulating every move of the either sides. But will things go wrong for them, like it did back then? Shall the doom of humanity be brought by its rotting heart, or shall they perish through the cleansing flame of the enemy? Can the combined might of the strongest galactic forces be enough to hold back the enemies?
