I can't remember the title of this fanfic, so I'm hoping anyone does.

Basically, Inu no Taisho comes across Kagome in a village. Kagome is a half demon whose father was a soldier siding with the Western lands and was killed in battle and her mother was stoned to death. Kagome is brought back to the Western Castle, where she meets Sesshomaru, Inuyasha and both of Inu no Taisho's mates (Sesshomaru's mother and Izayoi. Sesshomaru's mother then takes Kagome to help her grow into her demon side, as she has a stunted growth due to not being around a demon's aura.
