Description
Biba Amatori is a central antagonist in the anime and a character whose actions drive much of the latter half of the story. He is a young man of 22 years with a striking appearance, characterized by long pink hair swept back from his face and golden eyes. Known publicly as a hero and liberator, he is the charismatic commander of the Hunters, an elite and independent fighting force celebrated for its success in battling the Kabane. This public image, however, stands in stark contrast to his true nature.
Born as the eldest son of the shogun, the ruler of Hinomoto, Biba was disowned by his father after a catastrophic military campaign. As a twelve-year-old, he led a large force to Kyushu to fight the Kabane, but his father, fearing his son's growing influence and popularity, deliberately cut off their supplies. The resulting defeat and the belief that he was betrayed by his own parent left deep psychological scars. This event became the crucible for his worldview and his ultimate goal: to destroy the shogun's seat of power, Kongokaku, and exact revenge on his father and the cowardly system he represents.
The core of Biba's personality is a cold, calculating, and ruthless adherence to the philosophy of survival of the fittest. He genuinely believes that the weak have no right to live and that strength is the only virtue. This belief allows him to commit horrific acts without hesitation, often with a calm or even pleasant smile on his face. He views the walled stations not as sanctuaries but as prisons that breed weakness and fear. His stated mission is to "liberate" people from these cages, but his method of liberation involves tearing down the walls and unleashing chaos and Kabane hordes upon the defenseless populations, forcing them to either fight or die. Behind his heroic facade lies a profoundly damaged individual whose sense of justice has been twisted into a desire for nihilistic destruction.
His relationship with Mumei is the most significant and tragic in his story. He saved her when she was a young, nameless girl after her mother was killed. In a pivotal moment, he gave her a sword and instructed her to kill the man responsible, teaching her that a weak person deserves to die. He then gave her the name Mumei, meaning "nameless," and subjected her to the process of becoming a Kabaneri, a half-human, half-Kabane being. She calls him "brother" and is utterly devoted to him, seeing him as her savior. However, Biba's feelings for her are purely instrumental; he raised her as the perfect weapon, a tool for his vengeance. He manipulates her without remorse, uses drugs to control her when her loyalty wavers, and ultimately plans to sacrifice her as a living heart to create a monstrous being called the Black Smoke. Similarly, he surrounds himself with other Kabaneri, including a woman named Horobi, whom he also discards without sentiment when they cease to be useful.
In contrast, his relationship with the protagonist, Ikoma, is one of antagonism and dark reflection. Both are Kabaneri who reject the fear and passivity of the established order. However, where Ikoma fights to protect the weak and find a way for humans and Kabaneri to coexist, Biba seeks to annihilate the weak and uses his power for domination. Ikoma is immediately suspicious of Biba's philosophy and is horrified by his cruelty, correctly identifying him as a far greater threat than the Kabane themselves.
As a military leader, Biba is a brilliant strategist and a formidable fighter. He commands the Hunters, a well-equipped force with advanced weaponry like mortars, incendiary rounds, and even a motorcycle corps. He is also a skilled scientist, having mastered the technology to create Kabaneri artificially. His own combat skills are exceptional; he wields a Western-style saber and fights with superhuman speed and precision. It is eventually revealed that Biba himself is a Kabaneri, having undergone the same transformation he forces on others. He possesses the enhanced strength and durability of a Kabaneri, though he keeps this a secret, perhaps because he also fears the loss of control that comes with the condition.
Over the course of the story, Biba's master plan unfolds. He uses the armored train, the Koutetsujou, as a tool to reach the capital. He systematically destroys stations by releasing swarms of Kabane he has secretly transported. Upon finally confronting his father in Kongokaku, he uses a poisoned blade to transform him into a Kabane and then kills him himself, completing his revenge. However, this victory is hollow. With his primary motivation gone, he becomes listless, and his actions turn toward pure destruction. His development peaks in his final duel with Ikoma. Despite being severely wounded, he reveals his own Kabaneri nature. In his last act, he injects Ikoma, who is on the verge of a complete Kabane transformation, with a white serum that stabilizes his condition. This ambiguous final gesture, which saves his enemy's humanity, is the only hint that some shred of his former self may have remained. He is ultimately killed by Mumei, who finally breaks free from his control, and his body is left to be buried in the ruins of the capital he sought to destroy.
