I am not sure if I read this on FFN or here, but it is one that I would love the read again. Inuyasha tricks Kagome into going into a temple with a dark aura. Kikyou is waiting there and takes her soul. Miroku comes in after Kagome into stasis so that she can use her powers to destroy Naraku. Miroku feels that Kikyou is lying, but lets his wish to live a long life with Songo cloud his judgment and he abandons Kagome. It turns out that Kagome had two souls (or something like that) so Kikyou taking one does not kill her. However, she later learns she is cursed because that temple was used to take the souls of mikos that had hanyou children.

This seems vaguely familiar. I'll have to think about it and see if I can recall the title.

Is it One Wish by Earthnfarie?

What is unknown to all is that this is the path of destiny and it must be walked.Inuyasha - Rated: M - English - Drama/Angst - Chapters: 19 - Words: 33,007 - Reviews: 136 - Updated: 11-16-10 - Published: 8-20-09 - Kagome & Sesshomaru - Complete
