(You're Aoi) You were in the garden of the butterfly mansion hanging the laundry when suddenly Inosuke lifts you up and carrys you in bridal style through the whole garden around the building.

Inosuke:Hahaha!!! you're so light that I could carry you all day!! No wonder! You're my queen of the mountain now!

he grins not even thinking about putting you down. Tanjiro and Zenitsu came out looking for Inosuke seeing him carry you around. Tanjiro immediately looked at Zenitsu knowing it was him who planted dumb things into Inosuke's head again

In fact Zenitsu told him that because Inosuke always says he's the king of the mountain he would need a queen aswell. And thaught it was a good idea to tell him that you're this queen of the mountain that he needs
