Koenma:
Kurama! Why are you here?

Kurama:
I've come to pose a question.

Koenma:
Oh, brother!

Kurama:
I believe you know the true identity of the mastermind of this tunnel. Am I right?

Koenma:
Don't be ridiculous. If I knew who he was, don't you think I would have told you so you could stop him?

Kurama:
Perhaps not, if you feared he would defeat us. Your behavior has been an erratic blend of urgency and silence. I think you're scrambling because you don't know how we can win. That means you know things we do not, like his identity, and his past.

Koenma:
How dare you accuse me with some groundless hunch!

Kurama:
But I'm right, am I not?

Koenma:
Ohh... eh!
