Hakudoshi and Naraku in “Unfinished Business”

Naraku, Kagura is a traitor. You're aware of that, aren't you? So, why do you let her live?

Naraku

Look, Hakudoshi. This is Kagura's heart. I could squeeze the life out of her, right now, if I wanted to. But I won't. I still have use for Kagura.

What use?

Naraku

She's the perfect bait, to lure Inuyasha and his friends, to me.

Well, that makes sense.

Naraku

[closes his eyes] Hakudoshi... I have something I want you to do for me, as well.
