Yuu(gi): Hey you there, mister.

S(am): ...You're talking to me?

Yuu: I don't see anyone else.

S: And? What do you want from me?

Yuu: How about having a duel? You're no ordinary human, as I see.

S: Now you mention it, you don't look ordinary either... but pardon me, I have lost my special weapon, moreover, I don't really like meaningless killing.

Yuu: If you want a sword, why don't you use the one hanging there. And this won't be meaningless.

S: What do you mean?

Yuu: If you win, I'll show you to the surface.

S: ...Where are we now?

Yuu: I'll tell you that too, if you win.

S: And if I lose..?

Yuu: You'll die here like a dog.

S: ...I see, this kind of duel. So be it.

Yuu: Hehe, that's what the oni do! They're the kind of character that gets an itch to compare their power when they see someone strong!

S: ...(To get to see an oni after a welcoming committee such as I met already... Rather unusual.)

S: So, this is what they call oni extermination. OK! Here I go!!
