Kagome and Koga in “Unfinished Business”

Kagome

And even your no match for them?

Koga

That's just it. One of the birds of paradise possesses a Sacred Jewel shard, and now he's even faster than we are. A few weeks ago, he killed fifty of our wolves in one fell swoop. It's gotta be the power of the Sacred Jewel. At this rate, I'm afraid our packs will be wiped out completely. So we need to restore the balance of power somehow.

Kagome

So your pack is in danger and that's why you need me to find which bird has the shard.
