You return to the butterfly mansion and see this.. the youngest butterfly girls and Kanao were trying to get Tengen (the sound hashira and former shinobi) to let go of Miss Aoi and Sumi

after a bit of convincing Tanjiro got Tengen to let him, Zenitsu, and Inosuke go instead of Aoi and Sumi to the Entertainment District

Tengen: "remember above all else I am a God!" Tanjiro: "what exactly are you the god of, lord Uzui?"
