(Alright so it seems Tsunade is the clear winner I read most of the comments and it seems like I'm not exactly doing great with diving into conversations in depth so i will start focusing on trying to make in depth conversations)
(the poll is starting to finally get traction so i will give it a day before choosing the love intrest)
After a few minutes Naruto asks "Hey old man, how long will it take to reach the bridge?"
And Tazuna Replies "Around a four hour walk if we're not interrupted by bandits."
Realising we will probably take around six hours to get to the location. I realise we will probably run into the Demon Brothers in two hours, or so because Kakashi implied in canon that they were to be tied up and waiting for capture which insinuates that team seven was already far from the village.
After a few hours I finally found what I have been anticipating from the start of the walk, a puddle used as camoflouge for the Demon Brothers. After we walk past them they zoom past us decimating Kakashi's Clone.
Realising they are now focused on us I yell out "I'll protect the bridge builder you focus on them!"
Naruto hearing my yell doesn't stand still like he does in canon reducing the time to take them out he still does get scratched by the weapon inflicting poison into his system.
After the fight Kakashi appears out of nowhere realising poison is in Naruto's system he says "We have to return to the village to heal Naruto and because the mission is out of our skill grade."
Naruto then stabs himself to get the poison out of his system doing so inflicted a wound that i would need to heal, walking over to Naruto i proceed to do a basic medical ninjutsu to remove small cuts and stab wounds. During this Kakashi brings Tazuna out of our range to question him on the true details of the mission.
After a another uneventful few hours of walking, we finally see the boat that we are supposed to use to cross to the coast of the Land Of Waves. After boarding there are a few uneventful conversations with Tazuna and his friend who is taking us to the coast.
Interrupted from my thoughts Naruto Screams "That Bridge Is Huge!" Earning a shut up from Tazuna.
After docking as far as Tazuna's friend will willingly take us we proceed to walk until Naruto Yells "Take That!" and throws multiple kunai into the bushes.
Kakashi realising Naruto was actually throwing a kunai at something, he proceeds to investigate after a millisecond Kakashi screams for us to get down. After we all dive to the ground a huge blade is thrown into the tree behind us. A man jumps onto the blade and introduces himself as Zabuza Momochi one of the Seven Swordsman of the Mist Village.
Kakashi finally realising the complete severity of danger the mission now has tells us to go into formation and to protect Tazuna. Remembering how he used a clone to attack the bridge builder first, I start to focus on the time it would take for me to take it out without making Kakashi's focus change from his real body in the mist. I was unfortunately kicked out of my thoughts by the amount of killing intent pressured on us.
Realising my mistake of losing focus Zabuza's clone finally comes in between us to kill Tazuna. Just before Kakashi focuses on the clone i take it out with my chakra scalpel to his clones lung.
Realising his clones failure he starts to attack Kakashi so he can fully focus on us to easily kill the bridge builder during their fight I remember I have the Double Suicide Decapitation Technique so when he gets Kakashi trapped in the water prison I will use Naruto's clones as a distraction to free Kakashi by making Zabuza release his grip on the prison.
