Tanjiro stops the Demon Slayer, Zenitsu Agatsuma, from disturbing the woman. He reveals he had hoped to die during Final Selection due to his weakness and low resolve. The two are directed by Tanjiro's Kasugai Crow to their next location, a large woodland mansion. They find two children, Shoichi and Teruko, who tell him a demon inside has taken their brother. He and a reluctant Zenitsu enter, leaving Nezuko's box outside when the children unexpectedly enter too. They are then separated by the supernatural rooms, moving to the beat of a drum. Tanjiro, with Teruko, encounters a large demon, the strongest one in the house. While looking for an exit, Zenitsu and Shoichi encounter another Demon Slayer, wearing a boar mask. Tanjiro witnesses the demon's Blood Demon Art, moving the room with the drums in his body, when the boar-headed Demon Slayer suddenly enters the room.
