Demon Slayer Corps

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

here are hundreds of Demon Slayers within the organization, however they are not officially recognized by the government. Demon Slayer Corps have not appeared in any part since Tackle Tendency, It possibly disbanded around 1940-1950.

## Structure

In order to become a Demon Slayer, an individual must pass the 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 without any aid from the outside world.

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 where as Kinoe 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:

 Mizunoe
 Kanoto
 Kanoe
 Tsuchinoto
 Tsuchinoe
 Hinoto
 Hinoe
 Kinoto
 Kinoe

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 the 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.

### Kakushi

Within the Corps, there is a cleanup crew known as the Kakushi, where the majority of them have no swordsmanship skills. The Kakushi are responsible for providing first aid to injured Demon Slayers following a large battle, as well as bringing the injured in for proper medical attention.

## Abilities

**Physical Abilities:** All Demon Slayers including lower-ranked members have enhanced strength, speed, reflexes, stamina, durability, endurance, agility and mobility, with the Kinoe, the physically strongest in the organization, having all aforementioned abilities at beyond superhuman levels.

**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.

**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.

**Demon Slayer Mark:** The Demon Slayer Mark is a mysterious supernatural marking that can be unlocked and may appear on the body of a strong Demon Slayer. The most talented Demon Slayers of the Demon Slayer Corps have a chance to develop a mysterious tattoo, scar, or birthmark marking. It resembles the demon crests that appear on the bodies of most demons. These marks are referred to as Demon Slayer Marks. It looks somewhat like a tattoo, scar, or birthmark and each Demon Slayer Mark looks unique, relating to the Breathing Style of the bearer.

## Techniques

**Total Concentration Breathing:** An advanced and esoteric breathing technique where a user inhales the maximum amount of oxygen within a specific breath pattern to raise their physical and mental prowess to their utmost limits. The effects include a plethora of enhanced physical and mental abilities, like superhuman physical characteristics (i.e. strength, speed, stamina, durability and agility), faster thought processes, concentration and information processing. This technique is also capable of clotting wounds from severe injuries and slowing down the circulation of poison in the bloodstream.

**Breathing Styles:** Swordsmanship styles that makes use of an esoteric breathing technique known as **Total Concentration Breathing** practiced and taught by the Demon Slayer Corps and are used in combat by Demon Slayers.

### Known Breathing Styles

**Repetitive Action:** A technique practiced and taught by a few individuals from the Corps, it allows a person to achieve the same effects as Total Concentration Breathing by repeating pre-set movements or remembering intense feelings to open the five senses and raise their concentration, drawing out the physical powers of the body for an long extended period. It is possible to use both Repetitive Action and Total Concentration Breathing simultaneously, granting the user immense strength able to rival higher rank demons.

## Equipments

**Uniform:** The members of the Demon Slayer Corps wear a uniform that is highly durable and light-weight, they are also water-resistant and non-flammable. The uniform cannot be easily damaged by 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 Swords:** Special blades used by and made specifically for the Demon Slayer Corps 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.
