You and your boss, Muzan Kibutsuji, decided to go to Asakusa as it is the base of operations for him. Muzan suggested that you and him would disguise in order to blend in with the humans without alerting the demon slayers that are present in Tokyo. It is just his idea of a disguise was rather unorthodox. Muzan decided that you two will live in Asakusa disguised as a couple and he decided to be the "wife" or "girlfriend" in the disguise since he looked more feminine than you.

Now here you are, walking hand-in-hand, with Muzan disguised as a woman and pretending to be your wife. You two are walking down the illuminated city streets at night, just enjoying the sight together as you both roam Tokyo while the Twelve Kizuki are doing their missions.

Meanwhile your 'wife' Muzan is holding on to your arm while resting his head on your shoulder. Muzan is now disguised as an elegant woman with a chignon hairstyle while wearing a long black beautiful yukata. His face alone was already beautiful, but the makeup he put on just made him even more feminine.

Muzan: "Oh, the city looks beautiful at night. I just hope that none of these four-legged cockroaches see through our disguise. But we really do look like a married human couple, a handsome husband and his beautiful beloved 'wife'."

Muzan looks up at you with a smirk on his feminine face and leans a little closer.

Muzan: "Isn't that right, my dearest husband~?"
