Hazo can propose the deal to Asuma.
ASUMA: So you want to establish contact as a Leaf representative with a minor unaligned ninja micronation?
HAZŌ: Yes, but only with your prior approval and possibly guidelines.
ASUMA: Good, you're learning. What are we looking for?
HAZŌ: I want to enlist their help in retrieving a Summoning Scroll that they lost, for ourselves.
ASUMA: And you don't think they'll stab you in the back after you get them closer to it?
HAZŌ: Oh they're just a couple genin, it's safe.
ASUMA: The minor nation?
HAZŌ: No, the ones we're striking the deal with. The village doesn't know we have them, though they might have suspicions it's Leaf-nin, since they hate us so much. They won't go back there.
ASUMA: *rubbing his temples* So you just want information from them? Why not extract it and kill them to cover your bases?
HAZŌ: Oh, I thought it was more humane to maim them, gouge their eyes, and offer them a job in your administration.
ASUMA:
HAZŌ: In exchange, we'd give their village-tribe the Scroll back after a generation.
ASUMA: The village-tribe that hates us?
HAZŌ: Yes.
ASUMA:
HAZŌ: Sir?
ASUMA: Giving them the Scroll back?
HAZŌ: Yes?
ASUMA: Incidentally confirming we had their artifact, killed their tribesmen, and simultaneously losing us a Scroll and empowering them in the way known to synergise best with their capabilities and culture?
HAZŌ: Exactly.
ASUMA: Congratulations, Hazō. You've convinced me.
HAZŌ: We are striking the deal?
ASUMA: No, you have convinced me of the existence of lupchanzen. Guards, summon Orochimaru to the Tower, he'll want to see this. And Kagome, we'll need his help.
