Description
Yasunori Kato emerges from the displaced Ainu tribes' ancient wrath against the Yamato, incarnating a two-millennia curse upon the Japanese Empire. A fusion of oni lineage and onmyōdō mastery, he wields dark shikigami, kodoku poisons, and goho doji to enact vengeance. Clad in a military uniform and cape, his white gloves bear Abe no Seimei’s pentagram, framing an unnaturally elongated visage that shifts across adaptations.
Hailing from Ryūjin, Wakayama, his ancestry intertwines with heretical branches of Abe no Seimei’s clan, merging oni blood with esoteric arts. Infiltrating the 19th-century Imperial Japanese Army, he ascends to First Lieutenant while covertly unleashing supernatural disasters. His ultimate scheme revolves around resurrecting Taira no Masakado’s vengeful spirit to obliterate Tokyo. Thwarted by Masakado’s resistance, he pivots to impregnating psychic medium Yukari Tatsumiya, crafting her daughter Yukiko as a vessel.
Spanning timelines, Kato engineers cataclysms: triggering the 1923 Great Kantō Earthquake by awakening the Underground Dragon, then harnessing the Firmament Dragon to destabilize the moon’s orbit. Opponents like exorcist Yasumasa Hirai and Keiko Tatsumiya—a miko channeling Kannon’s mercy—repeatedly counter him. Keiko’s compassion fractures his hatred, dissolving his form temporarily.
His influence permeates WWII, enabling a Buddhist curse to assassinate Franklin D. Roosevelt, and corrupts author Yukio Mishima during 1960s turmoil to erode Japan’s stability until Mishima’s suicide disrupts the plot. Reemerging in 1998, he provokes earthquakes via water dragon Ryūjin, exposing himself as Masakado’s wrath incarnate.
Alternate narratives expand his reach: his spirit possesses a nurse in 1995’s *Teito Monogatari Gaiden*, while 2005’s *The Great Yokai War* sees him commanding mechanized yōkai until a child wielding Kirin Rider power dismantles his legion. Sustained by shijie rituals and a diet of human organs, he regenerates injuries, resists mortal harm, and leverages fluency in Mandarin and Korean to ally with anti-Japanese factions. Though often solitary, some accounts depict him orchestrating cults or collaborating with revolutionaries, intertwining occult stratagems with geopolitical sabotage.
His curse ensures perpetual resurgence, surviving repeated defeats. Beyond fiction, his legacy inspires villains like Street Fighter’s M. Bison, cementing his status as an enduring emblem of ancestral retribution and mystical threat.
