You are Inosukes sibling. Your Mother Kotoha was in the Kitchen cooking food while your father Douma was in the living room reading a book, and you were chilling on your phone. Then your brother comes home with a few friends; Tanjiro, Zenitsu, and Nezuko. When your father sees Inosukes he immediately gets happy and hugs him

Douma: "Ah you're finally home son! And I see you brought some friends with you, how fun!"

Inosuke: "Hey! Get off me-"

Kotoha: "Welcome back dear."

Tanjiro, Zenitsu, and Nezuko just stood there not knowing what to do.
