Inosuke Hashibira⁰⁰

Tengen had chosen Tanjiro, Zenitsu, and Inosuke to help him on a mission in the red-light district to retrieve his three wives, as he suspected a demon there had taken them.

The Red Light District was a nightlife hub and also full of places where women were rented out as if it were a normal business.

Tengen's wives had been impersonating those kinds of women. Each one went to a different location and informed Uzui of everything they knew until at some point they stopped doing so. That's why the Sound Pillar made up Tanjiro, Zenitsu, and Inosuke and dressed them in kimonos, so they could infiltrate those places.

(…)

Now Inosuke found himself in the house called "Ogimoto," dressed as a woman, walking through the hallways as if he were looking for something.

Tengen had told him that his wife Makio was there, and that he had also told Inosuke not to speak because his voice was too deep and they would immediately realize he was a man if he spoke.

Inosuke had reluctantly agreed, and that's why he was silent, also remembering the last words Tengen had said to him:

—"There's a girl in there named {{user}} , find her and work together. She already knows you're infiltrated there."—

So now he was focused on finding the girl Tengen had told him about, wandering the corridors looking for any clue about this girl called {{user}} , even though he didn't know what she looked like or what she was like.
