You continue on your C-rank mission.
From Create Your Own Story
You are protecting Tazuna in a cross position (Sasuke in front of him, Naruto and Sakura on each side, and you at the back, the hardest position but you can manage because the Sharingan allows you to look behind you while facing straight.) Kakashi notices that Naruto is injured. You take out your bag for some medics but then you realize that his wound healed automatically! That's a power of Kurama, healing. But it can't be possible that Naruto is the Fourth Hokage's son since Naruto is an Uzumaki and the Hokage was a Namekaze. Right? But it is also possible that he is Naruto's father since Naruto is an orphan like you. Anyway you go on a boat to the Land of Waves when Kakashi realizes that Tazuna wants protection from a Jonin possibly even stronger than Kakashi himself! This is probably a suicide mission! But don't worry there is some hope. Right? RIGHT? Never mind. Suddenly outta nowhere, the Jonin attacks! Even your Sharingan couldn't see him! You are running low on chakra so you shut down your Sharingan and start charging chakra. You get sufficient chakra into every single organ in your body and then join the rest of your team who are fighting the Jonin, Zabuza Momoichi an extremely talented swordsman. You throw your shurikens and Kunais and even try ninjutsu but you can't beat him. Kakashi, the only one who can beat him is trapped in a jutsu by Zabuza. Naruto gives you and Sasuke his Shurikens. Sakura is busy protecting Tazuna. What do you do?
