The sixth chapter of Ninja Kamui opens on a riveting note, with breaking news splashing across screens – an explosion rocks AUZA City, setting the stage for an atmosphere charged with tension. Hard on its heels, an anonymous voice commandeers the radio waves, inciting the populace to embark on a hunt for Higan, who has narrowly escaped the aftermath of the blast.
In a secretive laboratory, amidst the echo of distant chaos, Higan awakens to find Emma, clad in sophisticated armor, towering over him. Emma unmasks her true identity: a covert operative belonging to an organization captivated by the enigma of Higan's resurrective powers, abilities that defy death's iron grip. Revealing her dual role as an FBI agent, she admits to being the same individual who supplied Higan with the intelligence that led him into AUZA City's labyrinthine heart. Yet, beneath her aid to Higan lies a layered agenda, one not entirely devoid of personal interests.
Across the city, miles from Higan's hideout, Mike stirs from a ten-day slumber, his body swathed in bandages. Jason breaks the news that AUZA has now cast its shadow over him too. Mike receives this revelation with composure, acknowledging that he's long been within AUZA's sinister crosshairs. He urges swift action, proposing they waste no precious moments and instead, plunge into tracking down individuals whose names grace a list plucked from AUZA's fortified servers.
As the narrative progresses, Emma dives into the creation of a groundbreaking armor variant, one that promises to elevate Higan's agility, adaptability, and lethality to unprecedented heights, empowering him to vanquish adversaries with unparalleled efficiency. However, the armor's completion hinges on a critical component: a power reactor buried deep within AUZA's fortified confines. The stakes are raised, the mission urgent, and the dance of destiny unfolds in this charged episode of Ninja Kamui.
Endowed with ingenuity, Emma uncovers an ingenious solution, successfully bringing the suit, named Kamui, to completion. This suit stands apart from others, operating on a highly sophisticated level. To harness its power, however, Higan must establish a synchronization with his nervous system. The narrative then unveils a pivotal twist: it was Emma who had rescued Higan on the tragic night his wife and child were slain. Posing as a clan assassin, she administered a series of needles that induced a state of cellular cryopreservation, placing Higan's body in a suspended state of animation—a procedure that could only be performed once.
As tensions mount, AUZA's assassins track Emma down, cornering her inside a mobile truck. A fierce battle unfolds, with Emma valiantly defending Higan. Yet, the armored assassin's strength and agility prove overwhelming. Despite her relentless efforts, Emma finds herself outmatched and overpowered.
In her dying moments, Emma reaches deep into Higan's subconscious, revealing the motive behind her selfless act. She confesses that Mari, Higan's wife, had once saved her life, fostering a lasting bond between them. On that fateful night, Mari had reached out for help, but Emma arrived too late to save Mari and her son. With Higan as the sole survivor within her grasp, Emma acted decisively to preserve his life.
With a heartfelt apology for her inability to save Higan's family, Emma bids him farewell. Just before the armored assassin can deliver a fatal strike, Higan achieves full synchronization with his Kamui suit, poised to unleash a torrent of devastation.
