Tsuzumi Mansion

Tanjiro realizes that the man who fell from the house has died, and the older child confirms it was not their missing brother, who wore a persimmon-colored kimono. After a tense exchange, Tanjiro and a reluctant Zenitsu prepare to enter. Tanjiro hands Nezuko's box over to Shoichi and Teruko, promising that what is inside will keep them safe if danger comes.

Inside, Zenitsu trembles and clings to Tanjiro for safety. The children, frightened by the sounds from the box, run in after them, and Tanjiro insists the box matters more than his own life. A sudden noise scatters the group: Zenitsu ends up with the boy, Shoichi, while Tanjiro is paired with the girl, Teruko.

Tanjiro notices the rooms shifting in time with a drum and comforts Teruko. They are confronted by a towering demon that Tanjiro identifies as the master of the house by its overwhelming scent. Elsewhere, Zenitsu and Shoichi search for an exit and instead open a door onto a figure in a boar hide mask, who bolts past them. As Tanjiro squares off against the demon, the room spins from its Blood Demon Art, and the boar-masked stranger smashes through the wall.

Tanjiro and Zenitsu enter the Tsuzumi Mansion after entrusting Nezuko's box to the children.

Shoichi and Teruko follow them inside, and the four are separated into pairs as the rooms rotate.

Tanjiro confronts the mansion's strongest demon, Kyogai, while Zenitsu and Shoichi encounter Inosuke Hashibira for the first time.

Part of the Tsuzumi Mansion Arc, this chapter is collected in Volume 3 and was adapted within the eleventh anime episode. It marks the first appearance of Inosuke Hashibira, the boar-masked Demon Slayer who becomes one of Tanjiro's closest companions.
