The final confrontation between the International Police Organization and the secret society known as the BF Brigade erupts at the legendary Tower of Babel, serving as the backdrop for a massive super robot war. This conflict draws from the broader tapestry of Mitsuteru Yokoyamas creative universe, incorporating characters and concepts from his various manga, including the hero and villain from Babel II, whose ancient struggle forms the larger framework for the battle. The narrative follows the escalating war between the two immense factions, with the true nature and meaning of the conflict changing as more information comes to light. Key narrative threads include the rivalry between characters Taisou and Alberto, though the origins of their animosity remain unexplored, and the mention of a powerful group called the Celestial Nine, of which only two members ever appear. The storyline was intended as a grand saga, with this chapter representing the siege and climax at Babel, following planned arcs such as Operation Domino, the assassination plot against the protagonist Daisaku, and The Day the Earth Stood Still. The awakening of a presumed ultimate enemy is set in motion, alongside the appearance of its destined counterpart from the Babel II mythos.
