Sasuke was treading through the woods of hidden grass. He got reports of food and valuables being stolen from the people in the village. Although the stealing was not that caught Sasuke's attention. The victims were found trapped in Genjutsu. The victims described a young man with demon red eyes, obviously he was describing Sharingan. Sasuke was the last Uchiha, so who could be this mysterious person capable of using this kind of power. Was there an Uchiha survivor or someone else who can cast a Genjutsu superior than Uchiha's.
