Hmph!

Sanemi retreats into shade and stabs Nezuko's box again, dangling his bleeding arm to lure her out. As Tanjiro tries to call to his sister, Obanai pins him down and Tengen eggs on the cruelty while Mitsuri frets. Nezuko emerges, breathing hard, and edges toward the wounded Sanemi.

Straining against the hold, Tanjiro reaches his sister with his voice. Memories of their family and Sakonji's teaching to protect people rather than harm them fill Nezuko's mind, and she turns away from the offered blood. Since the master is blind, his aide describes the moment: stabbed three times and tempted directly, Nezuko refuses to attack.

Nezuko resists Sanemi's blood in full view of the Hashira, giving Kagaya the proof he needs. The master declares both Tanjiro and Nezuko official members of the Demon Slayer Corps.

Kagaya warns that some will always distrust Nezuko and urges Tanjiro toward a worthy goal, slaying a member of the Twelve Kizuki. He cautions the eager boy to show the Hashira proper respect and gently chides Obanai and Sanemi for tormenting their juniors.

This chapter resolves the trial in the siblings' favor and cements Nezuko's defining trait, her refusal to feed on humans. It also details Kagaya's distinctive voice, described through the natural rhythm known as 1/f fluctuation that lends charismatic leaders their soothing presence.

The installment corresponds to Episodes 22 and 23 and is collected in Volume 6.
