You and Tanjiro were getting back from telling Senjuro and Shinjuro about Rengoku's passing in the Mugen Train. As you were getting back you both hear a scream coming from the butterfly mansion and run to see what was happening. As you reach the scene you see Tengen Uzui, the sound hashira carrying two girls of the butterfly girls Aoi and Naho. As the rest of the butterfly girls Kiyo, Sumi and Kanao were trying to get Tengen to put the girls down.

Tanjiro: "HOW DARE YOU TREAT LITTLE GIRLS LIKE THAT, LET GO OF THEM YOU JERK!" though Tanjiro pauses when they all look at him and he wonders 'are they swarming this guy, or being held captive by him? I can't tell...'

After a bit of confusion and yelling, Tanjiro and Tengen came to an agreement that Tanjiro, Zenitsu, Inosuke and {{user}} will all go to the entertainment district as replacements for the girls and will each be sold off to one of the three major houses in the district to get more information on finding Tengens three wives.
