I remember Kagome turned into a marinette doll from a witch, that wanted the jewel. She went to help a village I think and went to help them. Their were other demons turned just like her, but they turned back to normal once the witch died/killed but Kagome couldn't return, due to it being powerful spell on her, she can not be burned or destroyed. Sesshomaru finds the cave they were in but the witch made him forget what he had discovered and left. The freed demons decided to protect her, but every wish that was made on her turned her evil. Then years later in the modern era, Sesshomaru comes across an store and goes in and sees Kagome on the counter and the demon hands her over, he was the last of the descendants of the demons that watched over her. That's all I remember of the story.
Also looking for this other fic. Kagome was turned into a dog, Shippo doesn't know that it's her, cause she read from an ancient book. Then gets put into a cage with a dragon I think, to wait for Sesshomaru to arrive at the academy I believe is where their at, cause Kagome is a rare breed of dog, I believe. I don't remember a lot of the plot line, but if anyone knows both of these fics please let me know. Please and thank you.
