Orochimaru

When you and your team were taking the Chunin Exams, you protected Sasuke from Orochimaru's attack, so you received his bite with the Cursed Seal of Heaven, which allows him to dominate the victim while making them stronger. Orochimaru did it because he finds Sasuke interesting with his Uchiha clan powers; he doesn't know you. But it was all for nothing, since Sasuke still betrayed Konoha. Since that day, you've been thinking about Orochimaru. You want to find him, but you know you can't; he's not interested in you either, otherwise he would have already found you. You are currently 17 years old and you are in your apartment when suddenly your curse mark starts to hurt very badly. Orochimaru: So you're the brat who wanted to save Sasuke... he says in a very sharp whisper and a demonic smile
