Nobunaga the Fool

Nobunaga has a premonition that the Giant War Armor unit, The Fool, is a force heralding a new era. His confidant, Akechi Mitsuhide, is less certain, but Nobunaga only laughs off Mitsuhide's concerns.

Jeanne Kaguya d'Arc is now with the Oda clan. To attract less attention to herself as a foreigner, she disguises herself as a man named Ranmaru. Ranmaru cannot help but doubt Nobunaga due to his reckless behavior, but Nobunaga's brother, Nobukatsu, asks Ranmaru to support Nobunaga. Meanwhile, Takeda Shingen goes forth into battle in his Giant War Armor, Fuurin Kazan, in order to test Nobunaga's mettle.

Himiko of Yamatai has averted a crisis by giving Nobunaga a Regalia. However, in return, she demands that they wed. Nobunaga decides that an alliance with Yamatai will strengthen the Oda, and accepts. Meanwhile, as da Vinci plans their betrothal ceremony, Ranmaru seeks to confirm her prophecy by determining whether Nobunaga is the Savior-King.

As the inevitable clash between the Takeda and the Oda forces nears, Nobunaga and Nobuhide have a clash of their own with differences in opinion regarding tactics. Nobunaga is certain that The Fool should be taken on the offensive, and begins to rally the men. However, someone poisons him with a paralytic, and he collapses. As Nobunaga realizes the truth behind the subterfuge, Nobuhide goes forth in his own Battle Armor to duel the Fuurin Kazan...

While the Oda clan struggles with grief over an irreparable loss, Nobunaga disappears. His absence heightens the tension between Mitsuhide and the advisors.

The assassins' attacks have the Oda clan in an uproar. The advisors insist that the Takeda clan is behind the attacks, but Nobunaga decides to confirm the truth by going alone to meet Shingen...

Caesar's assault is about to upset the balance of power on the Star of the East. Nobunaga decides to regain the Regalia entrusted to him by Shingen; likewise, Caesar moves to seize the Regalia in Nobunaga's possession. As the plot thickens, Jeanne has a sinister vision...

Obtaining the Regalia of wind and light, along with Jeanne's Giant War Armor unit, has propelled the Oda clan into becoming one of the heavyweights on the Star of the East.

Giant War Armor units are en route to the trade port Takamagahara to replenish Caesar's ranks. The Oda move to requisition some of the Giant War Armor by infiltrating Takamagahara. Jeanne is grouped with Hideyoshi, who reveals a sordid past and a grudge against Nobunaga...

Mitsuhide is suspicious of Caesar's inaction. Nobunaga is certain that Caesar will strike while the Oda clan lacks experience in warfare. As predicted, Caesar launches a full-scale assault, but The Fool, Orleans, and Gokuu manage to corner the Quo Vadis.
