Demon Slayer Corps

The Demon Slayer Corps is an organization that has existed since ancient times, dedicating its existence to protecting humanity from demons.

Overview
Operating in secrecy, the Demon Slayer Corps exists as an organization that is not officially recognized by the government. This clandestine nature necessitates that Demon Slayers cannot openly carry their swords while in public. The majority of people are unaware of the existence of demons, and even if Demon Slayers were to reveal the truth about their job and weapons, they would be met with skepticism and disbelief from most individuals. Allowing Demon Slayers to openly wield swords would only incite chaos and confusion among the general population. Nevertheless, whispers of the Demon Slayers have permeated public consciousness, existing as mere folklore in the minds of some. This is evident when a civilian witnesses a Demon Slayer engaging a demon firsthand, coming face-to-face with the reality of their existence and the truth behind the tales they've heard.

The Oyakata's unique gift of foresight has enabled him to avert disaster and accumulate considerable wealth. These resources are utilized to sustain the daily operations of the Corps, ensuring that Demon Slayers have the necessary support to fulfill their duties.

History
The Demon Slayer Corps is founded around a thousand years ago during the Heian period after a distant relative of the current Ubuyashiki family named Muzan Kibutsuji inadvertently became the very first demon. On advice of a priest, the Ubuyashiki family established the organization and assumed the responsibility of leading the battle against the demon progenitor and his demons, as eradicating the world from demons would break the curse that bound them.

During the Sengoku period, a talented swordsman named Yoriichi Tsugikuni joined the Corps after his wife was killed by a demon and taught the existing Demon Slayers a swordmanship later known as Sun Breathing. However, no one could match his form exactly. He modified the breathing techniques to suit their strengths, allowing them to gain a similar increase in power and abilities to help them hunt demons. The variations he created formed the first Water, Wind, Flame, Stone, Thunder Breathing techniques and the best of these Demon Slayers became known as the Hashira.

Ultimately, after a millenium the Corps succeeded in killing Muzan after a long and arduous battle. With the demise of the demon progenitor, his creations were also eradicated from existence. This decisive victory marked the end of an era and brought about the disbandment of the Corps.

Oyakata
The leader of the Demon Slayer Corps, revered as Oyakata-sama (お) by his subordinates, serves as the head of the organization and is traditionally a member of the Ubuyashiki family. He undertakes crucial responsibilities such as coordinating the deployment of Demon Slayers to areas plagued by demon activity, overseeing the Final Selection for aspiring Demon Slayers, and conducting meetings with the Hashira, the highest-ranked members of the organization.

Demon Slayers
The Demon Slayers (り) hold the forefront position within the organization. There are hundreds of skilled and dedicated individuals who have taken up the noble duty of hunting down and eliminating demons. Among the ranks of the Demon Slayers, a select group of elite Slayers possessing extraordinary skills in a specific Breathing Style are known as the Hashira, and their apprentice and eventual successor are known as the Tsuguko.

Cultivators
Cultivators play a vital role in nurturing individuals to become Demon Slayers. Each of them employ their own methods for training and are specialized in a specific Breathing Style. When a cultivator deems their student ready, they grant permission for them to participate in the Final Selection. If the student survives the selection, they will be accepted as a Demon Slayer in the Corps. Cultivators are few in number and dispersed across various locations. Most of them has a background as skilled Slayers who retired for various reasons. After retirement, they dedicate themselves to cultivating worthy successors. Renowned figures such as former Water Hashira Sakonji Urokodaki and Thunder Hashira Jigoro Kuwajima exemplify the role of Cultivators in the Corps.
