long ago Inuyasha's mother izaioy had a baby girl 2 years after Inuyasha was born. her father the same as Inuyasha's. Inunotasha the king of dog demons and ruler of the west. Her name. Keyuki.
There was nothing that could separate key and inu even after there mother died they stayed together.
That is until naroku turns Keyuki and makes her hurt Inuyasha and the priestess. After this she is thrown down the boneeatters well never to be seen again
that is until the shekon jewl is shattered and some shards seek through to true cross academy.
Keyuki and her best friend Rin Okumoru go to find the source of the shards. They end up joyning inuyasha and his friends.
But when she wants to live with rin for the rest of her life. She must first face and overcome her past with naroku
