RecordNine-Tails Hunt (Kyubi Gari)
A common name for a large-scale armed uprising that occurred in the Deep Realm's major city, "Sanzen Ohashi."

▶ Background
The incident began when a discarded soul, exceeding its luminosity limit, was left unattended due to the negligence of the responsible Koushi and was brought to the Nine-Tails.
Unaware of the situation, the Nine-Tails accepted it, resulting in the loss of mental and physical control due to excessive interference from the soul. A reign of madness and persecution of residents and mixed-bloods began.

▶ Course of Events and Conclusion
Reports from the residents to the Koushi were ignored and not recorded.
After several months of tyrannical rule, the residents decided to launch an armed uprising. They defeated the Nine-Tails clan, including the ruler, and their guards, ending the tyranny. However, a large part of the city was burned down, resulting in numerous casualties among both pure-bloods and mixed-bloods.

▶ Aftermath
The Deep Realm's upper echelons processed this incident as an "accidental rampage of a soul." The name and records of the responsible Koushi were kept confidential.
Discrimination and persecution against the Nine-Tails yokai continue in Sanzen Ohashi to this day, and this incident is remembered as a symbol of bloodline discrimination, management responsibility, and information control within Deep Realm society.
