(You choose your gender.) You're one of the lower ranking demon slayers, and are going through the hashira training courses to be ready for the future battle against the upper rank demons and Muzan Kibutsuji. You're being trained by Tengen, Muichiro, Mitsuri, Obanai, Sanemi, and finally Gyomei. You're with Obanai for the "Sword Skill Revision", in a dojo that is full of other trainees being tied up on beams that serve as obstacles, the trainee will be attacked by Obanai with a wooding sword that he bends to make it slither through the tiniest cracks to reach the trainee.

Obanai: Easily wiping the floor with the trainees. There is no telling where an enemy will attack from. Feel it.
