Episode 13 of Ninja Kamui dramatically unfolds with Mike receiving startling news—both the White House and the Pentagon have fallen under siege. Additionally, the power plant that Joseph had ominously vowed to detonate has also come under attack. All signs point to the Yamazi and their ninja forces as the perpetrators behind these devastating strikes.
Mike's phone rings abruptly, and it's Jason on the line. Jason divulges that Joseph is hiding out at the AUZA Palace Hotel, a fortress protected by an impenetrable security system bought with vast amounts of money. Joseph's intentions are clear: to flee the country and escape justice. However, Mike thwarts Joseph's escape plans and apprehends him just before he can board the plane.
Joseph makes a desperate attempt to trigger the power plant's explosion, but Jason's exceptional hacking skills intervene, jamming the signal and averting disaster. Defeated and cornered, Joseph has no alternative but to raise his hands in surrender. He mocks Mike about Emma's demise, probing Mike's resolve. Yet, Mike maintains his composure, refraining from taking revenge. Instead, he places Joseph under arrest and vows to ensure that he spends the remainder of his days confined behind bars.
Recall, the White House and Pentagon are now under Yamazi's control, with crucial leaders held captive. America had been misled to believe that Yamazi and Auza were collaborating on the construction of power plants to bolster the nation's economy. Little did they know that Yamazi's true objective was to utilize these facilities as strategic command posts for launching attacks anywhere, anytime.
Now, Yamazi aspires to broker world peace, but his vision is twisted—he seeks to dismantle existing governments and elevate himself as the ultimate ruler. However, one significant obstacle still stands in his way: Higan, the most formidable ninja the clan has ever trained.
In the climactic confrontation, Higan and Yamazi clash donned in their formidable Gusuko armor. While Higan's armor bears imperfections and relies on a finite portable energy core, Yamazi's gleaming suit stands flawless, unhampered by such limitations, capable of enduring indefinitely. This disparity grants Yamazi a formidable edge, as Higan's armor's power could dwindle at any moment.
The battle ignites, with Yamazi deftly countering every one of Higan's strikes, displaying remarkable prowess. To everyone's astonishment, Zai enters the fray, aligning himself with Yamazi. As Higan begins to falter under the pressure, he unleashes his secret technique, "Serenity," allowing him to delve into his opponent's mind. Penetrating Zai's thoughts, Higan reveals the true, monstrous face of Yamazi. Witnessing this revelation, Zai's loyalty wavers, and he ultimately switches sides, a turn we've been eagerly anticipating since the narrative's inception.
Despite Yamazi's formidable abilities, which momentarily incapacitate both Zai and Higan, Higan astonishes everyone, including his adversary, by unveiling his second ninja art: Thunderclap. With this devastating technique, Higan emerges victorious, vanquishing Yamazi.
With Yamazi vanquished, the loyal ninja contingent infiltrates the White House and Pentagon, securing the liberation of all those held captive.
In the aftermath, Zai stands tormented, contemplating seppuku, lost and directionless following his pivotal role in defeating his former leader. However, Higan steps in, reminding Zai that they still bear a purpose and a duty to honor the memories of those who placed their trust in them and made ultimate sacrifices.
Higan believes that Mari, his late beloved, would have desired a peaceful life for him, and he vows to live accordingly in her memory. Similarly, Mari, with her profound understanding of Zai's internal conflict, wished for him to transcend the ninja beliefs that shackled him, embracing his authentic self.
