A little bit of Shaku × Kikyō × Naraku, but not much. Most of it is a Kikyō-focused solo pairing.
Kikyō is still Kikyō in this life, but she also carries memories of her previous life, having come from a distant eastern land.
She protects the village, is wounded by Naraku, and seals Inuyasha away...
After her death, part of her soul wanders into the Netherworld along the path of hell, driven by her obsession. From then on, she sets out on the road to becoming the Lord of the Dead.
