Kakushi

The Kakushi are a brigade of people who work as attendants to the Demon Slayer Corps.

Overview
The Kakushi are a brigade responsible for different tasks pertaining to providing support for the Demon Slayers, which include:


 * Providing first aid to Demon Slayers on the battlefield.
 * Cleaning up the battlefield after battles.
 * Guiding the wounded and injured Demon Slayers to the Butterfly Mansion for further recovery.
 * Serving as attendants of the Butterfly Mansion, where they provide aid to the manor's residents and those healing on the premises.
 * Sewing and repairing the uniforms Demon Slayers wear.
 * Transporting people to and from the Swordsmith Village.

Joining
It is unknown how many members the Kakushi have, as well as how they recruit members, making these members quite mysterious. In some cases, Kakushi members are retired Demon Slayers or Slayers who have been injured or disabled to the point they can't fight anymore. There are also individuals who failed to pass the Final Selection examination but became Kakushi in order to still be of use to the Demon Slayer Corps.

Attire
They wear dark versions of the standard Demon Slayer uniforms consisting of a modified gakuran jacket and hakama pants. Said gakuran jacket has a longer hem and puffed sleeves to allow them to move freely, with the kanji of the brigade's name inked on the back (隠). Their forearms and their shins are covered in a black stretchy fabric, securing their sleeves and hakama respectively. For footwear, they wear plain white tabi socks connected to reed-colored zori flats.

To protect their identity, they wear dark head coverings with white linings, and a paper-like mask with three dark lines is tied around their face, divided in two sections, one in the front and the back, left to hang freely to allow them to speak and breathe easily.

History
During the golden era of the Demon Slayers in the Sengoku period, a traitor Demon Slayer named Michikatsu Tsugikuni became a demon and soon after killed the then-acting leader of the Demon Slayer Corps. He took the leader's head to Demon King Muzan Kibutsuji. Ever since then, more effort was put into hiding the residence the Corps' leader lived in. This was the time when the Kakushi were first formed.

With Muzan's defeat and the Demon Slayer Corps' officially disbanding, the Kakushi also ceased to exist.

Trivia

 * The kanji used for the brigade's name means "hidden" (隠). Other meanings include "conceal", "invisible", "pity", "sympathize", which overall reflects the nature of their work.
