"Captain, how much longer do you think it'll be before Kirigakure gets here?"
"I don't know! You've been asking every day since last week. Aren't you tired of it? Keep watch and don't slack off."
"But Captain, why am I the one keeping watch every time while you rest beside me?"
The older ninja pulled out a crumpled pack of cigarettes. After rummaging through it for a while, he lit one, took a deep drag, then slowly exhaled the secondhand smoke.

"You sure know a lot. Questions, questions, questions. Focus on your mission. I'm the captain, so just listen to me, got it?!"

"Sir, there are two chakra signatures six hundred meters ahead. One is about as strong as mine, and the other is about as strong as those brats who just graduated from Kirigakure."
The scar-faced ninja took out his specially made weapon, resembling an oversized senbon, and licked it by his mouth. "Good. I'll make a name for myself in this war and earn the right to inherit Nuibari!"
The three of them immediately concealed their tracks
