Description
Kato is the central antagonist of Doomed Megalopolis, a figure of immense supernatural power whose motivations are rooted in an ancient, deeply personal vendetta. He is an onmyoji, a master of the esoteric Japanese art of onmyodo, but he wields this spiritual discipline for destructive and malevolent purposes. Kato is not an ordinary man; he is an oni, a demonic or ogre-like being. According to the narrative, he was born from the collective grudges and resentful souls of ancient mystics and indigenous peoples who were conquered by the imperial Yamato court centuries ago. This makes him more than a simple sorcerer; he is the living incarnation of a two-thousand-year-old curse against the Japanese Empire and its capital city.
His personality is defined by a cold, almost serene cruelty and a profound, unyielding resentment. Kato is a calculating and relentless bully who derives satisfaction from the suffering of others, particularly targeting women and those who try to protect them. He speaks in a calm, often monotone manner, which makes his sudden outbursts of violence and sadistic glee all the more unsettling. Kato is portrayed as charismatic in a horrifying way, capable of manipulating and corrupting those around him to serve his grand design, though he is utterly devoid of empathy. He feeds on hatred, and his own existence is fueled by this negative emotional energy.
Kato's primary motivation is the complete annihilation of Tokyo, which he views as the symbolic heart of the empire that destroyed his ancestors. To achieve this, he seeks to awaken the vengeful spirit of Taira no Masakado, a historical warlord who rebelled against the emperor and, in the story's lore, slumbers as the guardian spirit of the city. Kato believes that if roused, Masakado will rise as a ferocious spirit of retribution and level Tokyo. His role in the story is that of the instigating force, a catalyst for a series of supernatural disasters, including the Great Kanto Earthquake of 1923, which he successfully triggers as part of his plan.
In pursuit of his goal, Kato forms several key, predatory relationships. His primary fixation is on two generations of women from the Tatsumiya family. He first targets Yukari, a young woman with latent spiritual powers, using her as a vessel in his ritual to awaken Masakado. When this initial attempt fails, he becomes obsessed with Yukiko, Yukari's daughter, believing her to be his own offspring and a more suitable medium for the warlord's spirit. Kato's interactions with Yukiko are possessive and abusive, treating her as an instrument rather than a person. He also develops a twisted fascination with Keiko, an older shrine maiden who resists him, driven by a desire to corrupt her pure spirit and force her to hate him so completely that she would transform into an oni and join him in hell. His adversaries are the Tsuchimikado clan, a lineage of legitimate onmyoji who serve the Emperor, particularly a master named Hirai, who stand as the primary obstacle to his schemes.
Throughout the narrative of Doomed Megalopolis, Kato demonstrates very little traditional character development, as he is presented as an already ancient and implacable force of nature. However, his arc is one of escalation: after a ten-year disappearance following his first failed ritual, he returns even more determined and ruthless, showing that setbacks do not deter him but only intensify his aggression. His physical and psychological attacks become more brutal, culminating in the catastrophic earthquake. A significant development in his character is his ultimate defeat, which comes not from physical force but from an act of spiritual compassion. When Keiko channels the celestial bodhisattva Kannon, her boundless compassion neutralizes the hatred that keeps Kato alive, causing him to violently disintegrate. This suggests that his identity is so wholly tied to his resentment that he cannot survive without it.
Kato's most notable abilities stem from his nature as an oni and his mastery of corrupted onmyodo. As an oni, he is nigh-immortal and cannot be harmed by conventional physical attacks. He possesses a powerful healing factor, capable of regenerating lost limbs, organs, and even his entire head. He does not age and is functionally immortal. His magical prowess is immense; he can perform telekinesis strong enough to throw vehicles, create impenetrable psychic barriers, teleport, fly, and generate powerful illusions for psychological torment, or mind rape. He is famous for his use of shikigami, which are spirits he binds into paper forms to do his bidding. His shikigami frequently take the form of black crows, tar-like blob monsters, or massive manta-ray-like creatures. He also employs kodoku, a form of dark magic involving insect or worm-like poisons, to control the minds of his victims. To sustain his powerful magic and prolong his life, Kato requires a diet of human organs, further underscoring his monstrous nature. He is also proficient with a katana, reflecting a background as a trained military officer.
