Yōkai taijiya

Yōkai Taijiya, (妖怪退治屋), are humans skilled at killing Yōkai. They are often paid to drive away and/or kill troublesome Yōkai.

Description
Demon Slayers are people who make their livelihood as "Yōkai Exterminators". They can combat and kill yōkai despite their lack of spiritual powers (like those possessed by monks and priests), due to many years of training, and the use of special weapons or equipment made to combat demons. Due to their strength, specialized weapons and skills, they are mistaken by some people to be ninjas. Something that is furthered emphasized by the fact their overall combat attire resembles a ninja outfit with armor and some bears their own customization like Sango's having a pink theme color.

Though they make their livelihood killing demons (Yōkai), they do not see all demons as a threat. In fact, they peacefully co-exist with demons who are friendly or do not pose a threat to humans. In the Demon Slayers' village (home to Sango and Kohaku), the nekomata Kirara lived in the village and aided the slayers in fighting yōkai.

They harvest the remains of the demons they slay, specifically the bones, to forge into weapons. Before that, they purified their jaki and calm their hatred. From then on, the weapon, carrying the consciousness of the slain demons, forge a bond with the slayer, seeing them as their companion, holding no hatred towards humans and fight by their side.

Though this is not an absolute case as when Sango sacrificed her Hiraikotsu without a second thought to save Miroku from the bone demon and its father, the demon spirits of the giant boomerang showed complete rage at Sango for sacrificing them like that when she confronted them while in the master of potions' potion dimension. However their anger and hate born from such an action can be pacified if they can feel the strong resolve a human shows like when Miroku willingly drank the potions master's potion that temporarily numbs his sense of pain when sucking in poisons through his Wind Tunnel for Sango. The demon spirits themselves also admitted that as demons, they don't understand the love that drove Sango to sacrifice them like that for Miroku but they understood the strong resolve Miroku displayed towards wanting to protect Sango which finally pacified them and impressed at the same time.

Abilities, Weapons, & Equipment

 * Enhanced Strength: As humans, they had trained themselves to attain strength at peak of human potential to fully utilize their various weaponry. Sango is shown able to carry Hiraikotsu which an ordinary human can't. Miroku himself wondered how someone as small as her was able to lift a weapon that heavy. She is also able to lift large rocks.
 * Enhanced Stamina: Through their constant training that they undergo since childhood, their stamina and endurance are much greater than ordinary humans and are at times considered superhumans. Sango is shown to be able withstand deadly wounds and still fight, she can also easily run at an impressive speed as seen in the first movie.
 * Weapons & Armor: Slayers use weapons & armor made from bones of slain Yōkai.
 * Hiraikotsu: Sango's main weapon is a massive boomerang which is made of the bones of yōkai that have been killed (a weapon owned by her grandfather that passed on to her by her father). Her grandfather used it to defeat Mistress Centipede (allowing him to obtain the Shikon no Tama from its carcass). The demon spirits in Hiraikotsu have refused to work for Sango in the final act. Hiraikotsu gains the ability to destroy demonic energy after getting repaired by the poison master.
 * Kusarigama: Kohaku's main weapon; a sharp sickle on a chain; the sickle is made of demon bone.
 * Dagger gauntlet: The dagger is hidden within her sleeve and can be retracted. In one particular episode Sango, who is possessed, uses this weapon against Miroku. Sango rarely uses this weapon mainly preferring the Hiraikotsu (it can be considered as a slayer's last resort).
 * Wakizashi: A short one-handed sword, sometimes mistaken for a katana.
 * Yōkai Paralyzing Poisons: A poisonous concoction that paralyzes demons.
 * Numbing Potions: This is mainly used when a slayer wishes not to kill a demon. The poison will numb the demon and the user normally masks the poison by baking it into buns or donuts.
 * Chain: The chains are used to constrict or hold enemies.
 * Mask: Protects the wearer from poisons and miasma from demons (it can also be used to protect slayers from the various gases the slayer uses).

Trivia

 * The slayers also seen to have a history with Myōga, possibly implying they have a history with Tōtōsai and the Great Dog Demon as well.
