Onmyōdō was once a potent art used by the Japanese in World War II to gain advantage and assert dominance. Japan fell swiftly after onmyōji Yakou Tsuchimikado unleashed the Great Spiritual Disaster, a calamity that still haunts Tokyo and casts an enduring curse over its people. In response, the Onmyō Agency was founded to exorcise future spiritual catastrophes and combat demons threatening humanity. The agency operates under secrecy, employing practitioners who blend ancient rites with modern techniques to detect and neutralize malevolent entities before they manifest, keeping the populace unaware of unseen battles.
Today Onmyōdō has evolved into a streamlined discipline applied to medicine, technology, and other fields. Yet the art remains inaccessible to many; Harutora of the Tsuchimikado branch exemplifies this. Though bound by a vow to protect Natsume—the heir of the main family and believed reincarnation of Yakou—as her familiar, Harutora lacks talent and chooses a normal life. When a senior Onmyō Agency operative seeks to repeat the experiment that doomed Japan, he resolves to honor his pledge and stands beside Natsume against the encroaching darkness threatening their world, ensuring hope endures amid chaos. Their unwavering courage inspires future generations to master the art responsibly and safeguard the world for all, today.
