Sadly, I don't remember much of the main plot but I remember a specific few chapters because it made me cry so much. Sesshomaru is unconscious and he can't wake up and the only way he can is if kagome invades his mind and helps him. She witnesses a past memory of when Sesshomaru was a kid and was help kidnapped and was raped by humans. She tries to help but realises it's a memory and h]Sesshomaru holds a lot of resentment for his parents because that only happened to him because of the war and they refused to negotiate for his release. I know it was a really good fanfic even if it did have that nauseating few chapters! Any information is greatly appreciated! If it helps I believe I first read it on fanfiction.net

Could it be "To Know the Man" by OnyxIvyStone?

Summary: Can we ever really know someone? Is there a way to see into their hearts and minds and pasts and understand what has made them who they are? Kagome is going to learn that the key to Sesshomaru's soul is what rests in the shades of what came before.

Rated: M but most likely MA here (edit by Wiccan: Definitely MA here, NO YIMs!)

I read this a couple of days ago because it was searched by Azuna. It's chapter 20 where Kagome made a soul link with Sesshomaru and see his rape.
