Soccer I finished Vash and i discarded that inuyasha model.
And kikyou is the priestess that kagome is the reincarnation of.
Shes the one that inuyasha was in love with but naraku led them to beleive they betrayed each other by attacking kikyou in the form of inuyahsa and she then pinned the real inuyasha to a tree with a magic arrow.
i think that explains who she is. also she was the protector of the village and the Shikone jewel
