Everyone assumed she hated her, but she doesn't.
Kikyo was always Inuyasha's first love, in a time where there relationship was scorned by everyone and he was hated for his blood. Love between a priestess and a demon, half or otherwise, was never meant to exist.
Yet despite all of this they had loved each other. She once thought Kikyo had only been using Inuyasha as a means to be rid of the jewel. The jealousy inside desperately trying to come up with a reason that would make Inuyasha choose her. But now she knows; she can see it in her eyes whenever the clay priestess looks at him. The love and sorrow makes her want to cry whenever she sees it reflected back.
Just when the two of them were about to live a normal life together it was ripped away from them by the manipulation of the man, no monster lying in pieces across the battlefield. Finished off by a combination of Kagome's arrow, Inuyasha's Windscar and a blast from Sesshomaru's Bakusaiga. The Jewel was taken and purified before his body could regenerate. Her makeshift family could finally start to heal, but not before Inuyasha got his chance at happily ever after. He deserved it more than anyone she knew. She couldn't say this wasn't going to hurt, but in time she knew she would get over it. After all love at fifteen almost never lasts, but she had to do something about the pain in their eyes whenever they looked at each other. And this was far better than him dragging him to hell anyways. So with a deep breath Kagome closed her eyes and made the only wish she could on the completed jewel.
"I wish for kikyo to be given a second chance at life."
