Inuyasha and Kikyo in “Unfinished Business”

Inuyasha

So are you saying Naraku was a diversion?

Kikyo

I'm certain of it. And that's not all. My shikigami were almost close to discovering something.

Inuyasha

What was it?

Kikyo

It seems that Naraku did not die by my arrow.

Inuyasha

Yeah. Even since Mt. Hakurei, he won't die, no matter how times I slay his body.

Kikyo

That can only mean that his heart is located somewhere else.

Inuyasha

His heart? So that's what he's trying to hide with the Fuhyoheki?

Kikyo

In order to destroy Naraku, I must find his heart.
