Description
Makoto Waltz Segai is a major character in the anime Guilty Crown, serving as a key antagonist throughout the series. He holds the rank of Major within the GHQ Anti Bodies, the quasi-governmental military force that occupies Japan after the outbreak of the Apocalypse Virus. Segai is a sharp and experienced intelligence officer known for his relentless pursuit of information, a trait that earns him the reputation of being too sharp for his own good. He is frequently seen wearing clown-like makeup and has a prosthetic left eye, which adds to his eccentric and unsettling appearance.

Segai possesses a charming and manipulative personality. He enjoys engaging others in conversation and often plays games on his cellphone, a habit that reflects his playful yet calculating nature. He is highly skilled at extracting information from his targets, using a combination of wit, deception, and psychological manipulation. His approach to his work is methodical and relentless; he treats every operation like a hunt, dedicating himself fully to exposing the secrets of his subjects once he sets his sights on them.

His motivations are rooted in a secular ideology that prioritizes the acquisition of power and knowledge. Segai is not driven by any grand political or moral cause but rather by a personal fascination with uncovering the hidden truths of the world and the people around him. He takes clear enjoyment in the game of information warfare, and his actions are often guided by a sense of amusement rather than loyalty to any faction. This makes him unpredictable and dangerous, as he is willing to betray allies or switch sides if it serves his purposes.

Within the story, Segai starts as an antagonist working under the GHQ hierarchy, specifically serving under Shuuichirou Keido. He initially appears as a supporting threat to the resistance group Funeral Parlor, but his role becomes more prominent as the series progresses. Segai develops an obsessive interest in Shu Ouma and the power of the Void Genome. He becomes a recurring obstacle, relentlessly pursuing Shu and his allies in an attempt to obtain the Void Genome for himself. This pursuit culminates in a direct confrontation where Segai launches an assault to seize the third Void Genome. He is ultimately defeated by Shu, who uses Yahiro Samukawa's Void shears to sever Segai's life force.

Key relationships in Segai's story include his professional connection to Shuuichirou Keido, whom he serves initially but later acts independently of. He also has a significant adversarial relationship with Shu Ouma, whom he views as a fascinating specimen to study and a target to capture. Segai interacts with other Funeral Parlor members as obstacles in his investigations but does not form any meaningful bonds with them.

Segai undergoes a subtle development over the course of the series, evolving from a methodical intelligence officer into a more personally invested antagonist. His relentless pursuit of the Void Genome ultimately leads to his downfall, and in his final moments, he comes to realize the true nature of the power he sought—the power of the human heart—a realization that lends a tragic dimension to his death.

In terms of abilities, Segai does not possess any supernatural powers. His strengths lie entirely in his intellect, investigative acumen, and manipulative skills. He is an expert at gathering and analyzing information, able to piece together complex situations and anticipate the moves of his enemies. He is also a capable combatant, though he relies more on strategy and deception in direct confrontations. His prosthetic left eye, while not explained in detail, appears to be a tool that aids his surveillance work. Segai’s lack of innate superhuman abilities makes him a grounded and compelling antagonist within a world full of powerful Voids and viral outbreaks.
