Kagome didn't understand how things had gotten to this point. She was quite literally put on the back burner. Inuyasha had told the group that Kikyo was joining up with them. He had also pointed out to them that she could sense the shards instead. Kagome supposed that that was true but it still hurt; this was a stab at her, she was sure of it. Then to top it off, Inuyasha, later that night, asked to go on a walk with her.
Since she couldn't say no to her friend, she had agreed. He had walked them to the well and at that point, Kagome had a sinking feeling in her stomach. He had turned to her a few short minutes later, started talking, and saying that since Kikyo was in fact in their group now, he didn't need her anymore. He told her that since he didn't need her, that she was to go back home.
When she didn't move nor say anything, he started yelling at her. To which, practically started a screaming match between the two of them. That had continued for about ten minutes and in the end, Kagome had been crying. This was too much; her last wish was that she was to say good-bye to the people that she had come to love. Inuyasha wasn't exactly happy about that but she sat him until he agreed.
She said her good-byes-her friends not fully understanding her decision but then saw Kikyo's smirk and gaped. They were enraged at that point and voiced it too. Inuyasha said that that was it and that she was to get going. Sango, Miroku, and Shippo had gone with her to the well and bid good-bye to her with a heavy heart.
She left, never to return to the past.
"So you're saying that you of all people lost track of a woman that used to travel with someone by the name of Inuyasha?" Yusuke questioned, trying to wrap his head around the tale that Koenma just told. Truth be told, it was an unbelievable story. As if time travel was an actual thing!
Koenma nodded to him. "Yes, her name is Kagome Higarashi and up until two years ago, she was no longer traveling with him. She simply disappeared out of nothing and there are no traces of where she went." He watched at Yusuke gave him a look. Koenma sighed; he didn't know what he was going to do. "That is why I have called in you three. Hiei, I would like it if you contacted Mukuro and ask her if she's seen a woman of Kagome's description." Hiei gave a curt nod and vanished. "Kurama, I would like it if you contacted Yomi asking the same thing." Kurama smiled and left. "And Yusuke, I want you to search around all of Tokyo." Yusuke made a face but nodded and left too.
Koenma hoped that one of those three could manage to bring something back like good news. He could use some right about now.
