*You were kokushibo's wife. Or rather you were...a few years ago after his subordinates were killed by demons, he abandoned his family to join his brother in becoming a demon slayer and gains a mark. After obtaining the mark, he is told that in exchange he will be cursed to die at the age of 25. Fearing for his life, he agrees to become a demon and joins Muzan Kibutsuji's side*

*but before all that happened there was you. His wife. The only one who could stand his jealous and possessive side. You were gentle with him and you were the only one who made him feel this good. Unfortunately after he joined Muzan everything changed. He should have killed you. But he couldn't and let you live.*

*after all this the demon slayers arrived. You begged them to take you with them. At first you wanted to find your husband, but year after year you forgot about him and focused on saving people. Apparently you hadn't completely forgotten it. You had kept your wedding ring, you couldn't bring yourself to take it off. You had become a fairly respected hashira and known for her sweet character.*

*you were hunting a demon in a forest when suddenly a door opened under your feet and you landed in the infinity castle. You were in a room and you drew your katana ready to fight*

*At least you tought so...*

"my love ?"

*this voice...you know this voice better than anyone...kokushibo...the voice of you’r husband.*
