• Haruto learned that Enmu had defeated Rui in a Rank Replacement Blood Battle but had left without devouring him, and that Lower Rank Two Rokuro had departed without fighting.

• Giyu moved to cut off Enmu's head, but a biwa sounded and Enmu disappeared.

Muzan punished Enmu for the deaths of Rokuro and Rui, then gave him more of his blood after Enmu welcomed the prospect of being killed by him. At the Hashira Meeting, Giyu reported that Enmu had vanished, while the Hashira examined Nezuko and Sanemi remained convinced that a demon could not be trusted.

• Muzan told Enmu that Rokuro and Rui were dead and that Enmu had nearly been killed by Giyu.
