Hey, im searching for a demon Kagome fic and I hope I remember the Story right.
Kagome makes a wish that give Kikyo her body, while she is now in spirit/soul/ghost form
Only Sesshomaru can see and hear her
Kagome helps Sesshomaru at his home, since no one can see her
Sesshomaru and Kagome encounter a kitsune or a inu-kitsune demoness who wants to mate sesshomaru
After the demoness is defeated Sesshomaru tells Kagome to lay in the body and binds her soul to the body with Tensaiga.
That is all I can remember, sadly
I would be nice if someone knows about it
