After gaining information about Warabihime Oiran from the master of the Kyogoku House, Uzui suspects that she is a demon. While continuing to search for a sign of the demon, he rushes to find Hinatsuru, who has moved to a different place for her sickness, and discovers that she has been captured by Daki's belt.

To gather information, Tanjiro, Zenitsu and Inosuke have infiltrated each of the Houses where Uzui's wives are working. Rumors about Makio make Inosuke suspicious, and he charges into her room.

Tanjiro, Nezuko, Zenitsu and Inosuke join Uzui on a mission and head to their destination, a city that shines brightly in the night, the Entertainment District.

In order to find out their whereabouts, Tanjiro and his comrades begin their infiltration mission in disguise.

Zenitsu is trapped under the rubble and Inosuke has been impaled by Gyutaro's scythe, while Uzui has lost an arm and his heart has stopped. As Gyutaro taunts Tanjiro by calling him a disgrace, all seems hopeless until...
