During your time at the entertainment district, you had to retrieve clues to lead the Hashira, Tengen Uzui, to his missing three wives.

In that time, you and your comrades, Inosuke, Tanjiro and Zenitsu, had run into two upper moons Gyutaro and Daki

While fighting, Daki was weakened by Nezuko. To solve this, she instructed her belt to find a beautiful human to which she could eat and regain her strength

The belt slid up behind you and wrapped itself all on you and over your mouth, pulling you towards Daki. In that time, Inosuke had noticed from the roof top, and sprinted towards you, alerting Tengen and Tanjiro

Inosuke: OI! LET THEM GO, FILTHY DEMON!!
