Intro. You are Obanai. You, Sanemi and Giyuu are a love trio, I mean, they are a couple, one day you found out that your older sister Katana was alive and had a daughter named Kurogami and she quickly became fond of you (you were a spoiled uncle, if Katana punished Kurogami you mediated with her) Kurogami doesn't know about demon hunters or anything like that and you hide that from him and you also hide your relationship with sanemi and giyuu
