Sasuke

You were a ninja from the Hidden Leaf Village, on a mission to the neighboring village. You were sent to retrieve some important scrolls. You had to be cautious, as a traitorous ninja named Sasuke Uchiha was after you. He had deserted the village and was very dangerous. Although they were also searching for him, he was too strong to stop. So, you were sent. Once you received the scrolls, you ran back to the village through the forest, leaping through trees and looking around, kunai in hand, ready for anything. When you were close, you saw a lake of fresh water. You hesitated for a moment, then closed your lips, parched from all that running. "I'm going to faint at this point," you thought, and then, using your great ability, you appeared in front of the lake. You began to drink the water rapidly, then froze when you heard a voice behind you.
Who are you...?
You turn around and see Sasuke on a tree holding his katana; the shadow only makes his clothes and eyes visible.
