The Kakushi (隠かくし Kakushi?) are a brigade of people who work as attendants in the Demon Slayer Corps. They wear black versions of the standard Demon Slayer uniforms, consisting of a gakuran jacket and hakama pants, as well as a black headgear and a black and white mask to conceal their identity.
The Kakushi are a brigade responsible for different tasks, which can range from providing services to Corps members to clearing the battlefield after Daemon attacks.
Other tasks performed by Kakushi include:
- Serve as attendants at the Butterfly Mansion , where they provide assistance to the residents of the mansion and those who heal themselves on site.
- Clean up the mess left behind after a big battle.
- Sew and repair Demon Slayer uniforms.
- Transporting people to and from the Swordsmen’s Village .
In some cases, Kakushi are demon slayers who have been harmed and ceased to be demon slayers. There are also individuals who did not pass the Final Selection Exam, but become Kakushi in order to still be useful to the Demon Slayer Corps.
