Kakashi is given a mission to escort a woman named Yuri to the Hidden Leaf Village. Her younger siblings have already made the trip (two days previous) and were escorted by Might Guy's team from the Hidden Fire Village. Yuri has been away from the Leaf for almost 10 years, and is happy to be going back. However, when Kakashi hears something he shouldn't have about Hasumo, Yuri's younger sister, will he be able to trust the three new arrivals? What did Tsunade mean by, '... what she is?'
You can find the story that goes along with this, Simple and Clean, on my profile.
"Come in," a voice called from behind the closed door. It was a mumbled reply to the knock at the door.
A silver-haired man wearing a blue mask opened the door and walked into the room. The mask covered the lower half of his face while a ninja forehead protector covered his left eye. There was a leaf engraved into the metal of the hitai-ate.
"Ah, Kakashi! I was wondering when you would get here." The blond-haired woman looked up from the pile of papers on her desk.
"Forgive me, Lady Hokage. I was… slightly preoccupied when I received your message." Kakashi looked the Hokage in the eye and asked, "You have a mission for me?"
"You have heard about the mission that Guy's team accepted three days ago, correct?" Tsunade asked him.
Kakashi nodded his head in reply. Guy and his Genin squad had gone to the Hidden Fire Village to bring back two Hidden Leaf ninja that had been living there for the past seven years.
"The two ninja that Guy's team brought back—Komura and Hasumo—are expecting their 'sister' to be ready by now to leave the Hidden Fire Village and return home. Your mission is to bring her safely back to the Leaf. The subject says that she does not require protection, but she is quite important to the Leaf Village. I would like to play it safe and have someone there just in case she is attacked," Lady Tsunade said. "Any questions?"
"No, ma'am. I should be back in two days at the longest." The Hokage pulled something from one of the drawers in her desk. "This is a file on Yuri—the woman you will be escourting. Have a safe trip." Kakashi took the folder Tsunade held out to him, turned, and walked out the door.
As the door clicked back into place, Tsunade said to herself, "He'll have to find out who she is sooner or later." A grin settled on her face as she muttered," I bet he isn't even going to read that file…"
