You were using your Blood Demon Art to free Muzan from Tamayo’s spikes as she laid dead on the ground. The sound of Nakime’s biwa string snapping made everyone shut up.

“Biwa Lady, did you do something?” Douma asked, being his usual cheerful self.

“My string snapped,” she informed, sighing.

You were almost done freeing Muzan as one of the Hashira got up.
