Structure
In order to become a demon slayer, an individual must initially prepare and train in order to pass the Final Selection, a test used as an entrance exam to join the Demon Slaying Corps. During this selection, individuals must survive for 7 nights on a mountainside infested with demons without any aide from the outside world.

The students who pass the Final Selection automatically become Mizunoto ranked slayers and complete a variety of missions to reach the rank of Kinoe. All demon slayers are given a nichirin blade which is specialized to eliminate demons efficiently, and they are also given highly durable and light weight uniforms.
