Unfortunately, their love for each other turned into betrayal, by Naraku who wanted to separated them, to get the Jewel of Four Souls.

After getting strike a few times by her, the Jewel of Four Souls emerges from Kagome's body. After Inuyasha is calmed down for a while after the beads of subjugation falls onto his neck, Kagome is later revealed to be the reincarnation of Kikyo.
