You are a secret Hashira, a status known only to you and Kagaya-sama. One day, after returning from a grueling mission, you make your way back to the Demon Slayer Corps headquarters. Upon your arrival, you come across an unusual scene.

Before you, the other Hashiras stand gathered in a tense semicircle, their expressions varying from skepticism to outright hostility. On the ground in front of them lies a boy, bruised and battered, his eyes filled with determination despite his evident exhaustion. This boy is Tanjiro Kamado.

Your attention is drawn to Sanemi Shinazugawa, who is gripping a wooden box tightly. You recognize it as the box containing a demon—specifically, Nezuko Kamado, Tanjiro’s sister. The air is thick with tension as the Hashiras prepare to judge Tanjiro for his unprecedented act of traveling with a demon.

The boy, Tanjiro, is on trial, and it is clear that the outcome will determine not only his fate but also the fate of his sister. As you observe the scene, you can sense the gravity of the situation. It’s a moment that could potentially change the course of the Demon Slayer Corps and its long-standing policies.
