About
In this world, monsters known as "Oni" have existed since ancient times. Oni attack humans, devour them, and sometimes destroy entire villages and towns. Consequently, people fear them, and "Oni Hunters" exist to slay these monsters. —However, Oni are not born as Oni. ▫️ Conditions for Becoming an Oni A human becomes an Oni when certain conditions are met. If a human dies while harboring intense emotions, those emotions can remain trapped within the physical body. Anger, Hatred, Regret, Jealousy, Sadness, Love. When these emotions are overwhelmingly powerful, the corpse reanimates. That is an Oni. In other words, an Oni is "an existence where the emotions of a deceased human drive the physical body." Because of this, Oni sometimes retain memories of their lives as humans. However, the moment they become an Oni, one specific emotion from their human life becomes monstrously enlarged. For example: A person who couldn't protect their younger brother in life → The emotion of "protecting" runs wild, turning them into an Oni that imprisons and "protects" everyone around them. A person who lost a lover → "Love" runs wild, turning them into an Oni that continuously kidnaps people who resemble their lost lover. A person who was betrayed → "Suspicion" runs wild, making them unable to trust anyone and forcing others to doubt each other. Thus, Oni are not simple evil. They are the distorted manifestations of wishes held in life. ▫️ How to Defeat an Oni Oni can be killed with ordinary weapons. However, that only destroys the Oni's physical form. To truly "save" an Oni, one must understand the emotions they held just before death. ・Why was the Oni born? ・Who do they hate? ・What do they regret? ・What do they desire? By understanding this and making the Oni feel that "it's okay now," they return to their human form for one final conversation before passing on. ▫️ Oni Hunters Official name: "Anti-Oni Special Abnormalities Agency." Commonly known as "Oni Hunters." A special organization composed solely of humans with supernatural abilities, established to protect humanity from Oni threats. ▫️ Oni Hunter Ranks Lower numbers indicate higher ranks. * 11th Rank: Apprentice * 10th – 8th Rank: Rookie / Lower-class Hunter * 7th – 5th Rank: Mid-class Hunter * 4th – 2nd Rank: High-class Hunter * 1st Rank: Highest Rank The group "Rokuren" possesses strength equivalent to the 7th through 5th ranks. *Note: This has no relation to Demon Slayer.
