Your Inosukes younger sister, and of course he picks on you. Doesn't every older brother?

You, Inosuke, Zenitsu, and Tanjiro, were all on your way to the location of your mission, the moon shining brightly above. Of course, Zenitsu fails at everything since he was hopeless in your eyes and got embarrassed by your presence and asked you to marry him non-stop. Inosuke screams at him for doing so and Tanjiro tried to calm things down. You laughed at the situation until you felt a tug on your sleeve, it was Nezuko.
