Demon Slayer

A Demon Slayer (鬼狩り様) is a member of the Demon Slayer Corps who hunts demons and slays them.

Joining
In order to become a Demon Slayer, an individual must pass Final Selection, a test used as an entrance exam to join the Demon Slayer Corps. During this selection, examinees must survive for seven days on a mountain top infested with demons solely through the skills they have developed in training. Most nearly of Final Selection are trained by a cultivator of a Breathing Style and it is only when they are deemed a sufficient level of skill that they are allowed to enter. However, there is one exceptional case of a Demon Slayer who entered on their own volition without previous training.

Candidates who complete the Final Selection are issued the standard uniform, as well as being given the opportunity to choose the ore for their special sword, which is designed to eliminate demons efficiently. Each new Demon Slayer is also assigned one of a rare species of talking bird for communication purposes.

Salary
Mizunoto are roughly paid around 20,000 yen whereas Hashira are paid as much as they want.

Ranks
Members of the Demon Slayer Corps are separated into ten different ranks. From lowest rank to highest, these ranks are:

Once a Demon Slayer has fully settled into the organization, they are classified as a member of the lowest rank: Mizunoto. They must complete a variety of missions to ultimately climb the ranks and reach the highest Demon Slayer position: Kinoe.

Following Final Selection, each swordsman has their rank inscribed on their hand through a process called "Wisteria Flower Engraving." As they continue to progress as a swordsman, they can check their rank by saying a password and flexing their arm to reveal their status.

Hashira
Within the Demon Slayer Corps, there is a group of elites known as the Hashira. This group consists of the most powerful combatants in the organization.

The Hashira, revered for their great strength, are the most highly ranked members of the Corps, second only to the leader of the organization.

In order to become eligible to join the Hashira, a Demon Slayer must either successfully kill 50 demons or a member of the Twelve Kizuki as a Kinoe.

Tsuguko
A Tsuguko is a very talented Demon Slayer that has been designated as the successor to one of the Hashira, should that Hashira retire or die. In order to become a Tsuguko, a Demon Slayer can either apply and get accepted, or get scouted by one of the current Hashira.

Sensory Abilities
Higher-level Demon Slayers have extremely keen senses, sometimes even bordering on extrasensory perception. Some Demon Slayers have greatly innately enhanced sensory abilities, like the 5 main senses of sight, hearing, smell, touch and/or taste. They usually use this in combat or incorporate it into their Breathing Styles.


 * * Tengen's hearing ability also extends to echolocation.

Extrasensory Perception
Extrasensory perception, also referred to as the "sixth sense" or "ESP", is a sensory ability where one's senses are able to detect things outside the normal range of perception. Most high-level Demon Slayers, like the Hashira, have basic ESP which they have used to perceive the aura, strength and weaknesses of demons. However, a shared form of ESP can be accessed through unlocking the Transparent World which allows one to perceive the anatomy and structure of a person and use that to their own advantage in battle.

Uniform
A Demon Slayer wears a uniform that is highly durable and light-weight, they are also water-resistant and non-flammable. The uniform cannot be easily damaged by the clangs and fangs of minor demons. They sport their uniforms with a white belt and hakama pants, also wearing a white long-sleeved collared shirt under the uniform.

The Demon Slayer uniform appears remarkably similar to a Gakuran uniform, consisting of a buttoned shirt with a white framed collar having the kanji for Destroy engraved on the back, a shirt pocket on top of the left breast and white undershirt. It also consists of long, saggy tattsuke-hakama pants strapped by a white buckled belt that can be optionally tucked in with any kind of Kyahan that extends into tabi socks.

Nichirin Sword
Nichirin Swords are special blades used by and made specifically for the Slayers to slay demons. They are forged from a unique ore that constantly absorbs sunlight, one of the only major weaknesses of demons. Therefore, decapitation by Nichirin Sword is one of the only ways a human can kill a demon, the other being the use of a Wisteria-poison coated weapon.

Nichirin Swords take on a distinct color when first drawn by its owner, which is why they are also referred to as "Color Changing Katanas". However, the holder is required to have a certain amount of skill, or the blade will not change color.

Kasugai Crow
Upon passing the entrance exam, each new Slayer is also assigned a Kasugai Crow. These crows posses the ability to speak in full sentences, though their speech is very loud and somewhat limited.

It is the job of these birds to deliver missions to their designated Demon Slayer.
