Master of the Mansion

Kagaya Ubuyashiki greets his Hashira warmly, and the swordsmen who moments earlier traded threats now bow before him in reverence. Even the hot-tempered Sanemi speaks to the master with deep respect. Tanjiro notes the leader's frail, scarred appearance and the calming effect of his presence.

The master announces that he has personally accepted Tanjiro and Nezuko and wishes the Hashira to do the same. The reaction splits the room, with Mitsuri and Muichiro agreeing while Gyomei, Tengen, Obanai, Kyojuro, and Sanemi object. To support his position, the master has an aide read a letter from the former Water Hashira Sakonji Urokodaki.

Kagaya gives the Kamado siblings his blessing. When the Hashira resist, he presents Sakonji's letter, in which the retired master pledges that he, Tanjiro, and Giyu will all commit seppuku if Nezuko ever harms a person, a vow that moves Tanjiro to tears.

The master then reveals that Tanjiro has encountered Muzan Kibutsuji, something no Hashira has ever managed, underscoring the siblings' importance. Unwilling to accept the argument, Sanemi cuts open his own arm and drips blood onto Nezuko's box to prove demons cannot be trusted.

This chapter introduces Kagaya Ubuyashiki and establishes the near-worship the Hashira hold for him. His reasoning, that no one can prove Nezuko will attack while three slayers have wagered their own lives on her conduct, shifts the trial in the siblings' favor.

The revelation of Tanjiro's contact with Muzan reframes the stakes for the entire Corps. The installment corresponds to Episode 22 and appears in Volume 6.
