Chapter 1

An Avenger's Sacrifice

"Wh-what did you say?!"

"I am no longer of use to Zabuza, I am a broken tool that has outlived its usefulness."

Naruto stammered as he looked at Haku in disbelief.

"Th-that's crazy! You're just a tool to him, he doen't even care about you!"

Haku nodded.

"I know."

Naruto snarled at Haku and lunged at him.

"I won't kill you, but I WILL make you pay for what you did to Sasuke!"

Haku smiled emptilly as he pulled several senbon needles from his cloak.

"Very well. Don't hold back."

Naruto charged with a kunai, swiping at Haku, which he blocked using a needle. Naruto then jumped back and forced himself to form a cross with his middle and index finger on each hand.

"Shadow Clone Jutsu!"

Releasing several shadow clones with his remaining chakra, Naruto charged Haku once more, this time fighting with his clones.

"Is that the best you can do, Naruto?" Haku threw several senbon, and each one hit it's target, but the real Naruto had vanished.

"Hm?" Haku looked around, trying to figure out where Naruto hid, then he felt a sharp pain in both shoulders.

"What?!" Haku looked up and saw two Narutos land beside him, they had snuck out in the clone ambush, then soared down onto Haku with a kick in each shoulderblade.

"Very impressive, Naruto..." One of the two Narutos vanished in a cloud of smoke, leaving the real one to look at Haku with sadness.

"How could you fight to kill a man, simply because Zabuza needs the money?! You're better than that. You're a shinobi! Have some pride!" He yelled angrilly.

Haku just smiled.

"Wouldn't you do anything for the ones you care about?"

Naruto trembled as Haku stood up and charged at Naruto.

"Sorry, Haku, but I won't let you die here, no matter how messed up you are." He said as a tear dripped from his eye. He slugged Haku in the stomach as he got in range, and the Mist-nin slumped over onto the ground.

Naruto then looked up as he heard a scream. Slowly the mist around him cleared, and he saw his sensei with a hand stabbed through the Demon of the Mist's chest.

"Kakashi-sensei!" Naruto yelled as he ran over.

"Very clever, Zabuza. You actually managed to shift your weight enough to move the attack, but it won't be enough. That wound will kill you, you know that."

The ninja in question chuckled.

"Killed at the hands of the Copy Ninja...I guess you have something else to brag about, eh Kakashi?" Kakashi removed his hand, and Zabuza began to cough rapidly as blood dripped from his chest.

Naruto continued to run over, completely unaware of the danger he was in. Kakashi looked up, eyes wide.

"Naruto get down!" But it was too late, an arrow was headed right for him.

Sakura looked over at Naruto in terror.

"NARUTO!!" As the genin cringed, waiting for the worst, he looked up and saw he was unharmed. Then he saw a certain black-haired genin in front of him, an arrow lodged in between his shoulder and neck.

"S-Sasuke!" Naruto yelled as his friend slumped down.

"That's the second time today I've taken a hit for you...Get it together, Loser..." At this, the Uchiha passed out. Naruto caught him and gently put him down on the ground. Then he looked up as he heard laughter.

"Zabuza, it looks like you failed me as well." A militia of hired goons stood before the leaf ninja and the Demon of the Mist.

"Look at you, a dog ready to be put down." The strange man laughed as he saw the wounded Mist ninja. Then he looked at Haku.

"That little runt!" He walked over and kicked the unconcious Haku.

"That's for nearly breaking my arm!" A kunai buzzed right over the man's head, with Naruto holding back a stream of tears.

"Touch him again, and I'll kill you." He growled. Then he looked at Zabuza, who just stood there.

"And you?! Are you going to let him do that to Haku?! He would do anything for you, and you'll just let him be kicked around like that?!" Zabuza just sat there stammering as his bandadged covered face became covered in blood.

"Not much I can do at this point...Besides, Haku served his purpose..." At this, Naruto took another kunai, turned it backwards, and threw it at Zabuza's head.

"You idiot! Haku would give his life for you! You're more important to him that his own life! Give him some respect! He's not just a tool, even if he thinks he is!"

Zabuza just listened to the genin as all of his memories with Haku began to flood his brain.

"..."

"Haku is alive, and breathing! If he were awake, he would have taken that hit for you! He would have died for you! Give him some honor! Show him some kindness!" Naruto continued.

Zabuza's face was covered in tears.

"Enough, brat."

"Huh?"

"Your words cut deep, deeper than any blade." With one bite, Zabuza tore off his bandages and looked at Naruto.

"Give me a kunai." Naruto just nodded and tossed Zabuza another knife, which he caught in his mouth.

"Gato! You will pay for this!" Zabuza ran through Gato's brigade of minions, killing half of them as he stabbed Gato in the chest.

"Burn in hell!" He yelled as he kicked Gato's body over the edge of the bridge. The rest of Gato's minions ran in terror of the demon, who then collapsed due to his coming death.

"K-Kakashi..." He whispered. The Copy ninja walked over to him and nodded.

"I understand." He immediatly picked up Zabuza and brought him to Haku's side. He then looked up at Kakashi.

"Take care of him for me."

"What?"

"He has no purpose now that I'm leaving. Give him a purpose, give him a reason to live..." He whispered as he began to choke. Slowly blood pooled from his mouth, and his eyes glazed over.

Kakashi looked away from Zabuza, and covered his Sharingan eye. He made sure nobody saw, but tears ran down from his face.

"Rest in peace, Zabuza Momochi. You finally regained your honor, and died a man worthy of the title Shinobi." Kakashi said quietly as his remaining team members tended to Sasuke. Kakahsi then looked at Tazuna. "We must take him somewhere safe."

"Of course, we'll return to my residence at once, we'll worry about the bridge later." Tazuna said stiffly. The man didn't show it, but he was quite worried as well. Kakashi took Sasuke, and ordered Naruto and Sakura to carry Haku.

Several days later, Sasuke was still unconcious. All the weaponry had been removed from his body, but he had lost a lot of blood, and his chances at survival were small. Nobody left his side, not even Kakashi. Then, he awoke.

Sakura looked on at Sasuke with great happiness.

"Sasuke!" She yelled. Sasuke looked at her with a very strained look of joy.

"Hey..." He looked at Naruto and chuckled.

"Loser, thanks. Cuz of you I'll never get to fulfill my destiny. Now that man will get away with his crimes..." Sakura looked at Sasuke in horror, was he saying he was going to die?

"S-Sasuke...?" She asked, voice trembling.

Naruto smashed his hand into the floor.

"I swear to you, Sasuke, I won't let him get away with what he did. I don't know who he is, and I don't know why you hate him, but whoever he is, I swear I'll kill him in your place." He said as tears dripped from his eyes.

"Only the Sharingan has a chance of killing him, Loser..." He whispered.

Kakashi looked up.

"There is one way. Sasuke, we could do an eye transplant." Kakashi stated, quite serious.

"Eye...Transplant?" He asked.

"If Naruto wants to beat this person, he'll need the Sharingan you say. We could give him yours. However, we need your consent first."

Sasuke smiled.

"Naruto, you better make sure you get him, cuz if not, I swear I'll haunt you till the day you die." he sneered.

Naruto smiled.

"I'll get him Sasuke! Believe it!" Sasuke just chuckled.

"What an idiot..." He said as he passed out again. Sakura sat there crying.

"S-Sasuke...Don't leave..." She cried.

Naruto looked away, knowing this was all his fault. Kakashi sighed.

"He hasn't got much time left. His body's giving out, that's obvious. We'll need to hurry if we want to keep his eyes healthy enough to transplant." He said bluntly. He then looked over at Haku, who was still asleep, hugging the only thing he had left of Zabuza, his sword.

Kakashi frowned.

"I should have known this mission was too dangerous. The first mission outside the village and already we lose a member..." Sakura snapped and punched her sensei.

"How dare you Kakashi-sensei! Sasuke is NOT going to die!" She screamed. Kakashi was unfazed.

"His body is failing, it's only a matter of time before his heart gives out. Sakura, you better realize that soon, because from here on out it only gets worse." He explained coldly.

Sakura sat there with tears in her eyes, and then glared at Naruto.

"This is all your fault, you stupid Idiot!" She screamed as she ran out of the room.

Naruto looked up, very disheartened.

"Sakura I..." Then he looked away as he saw she was gone. Kakashi shook his head in annoyance.

"Naruto, just leave her be. When the time finally comes, I'll deal with her." Naruto looked at his sensei in disbelief, Kakashi was actually going out of his way to HELP him? He just nodded, clearly dumbfounded.

Kakashi smiled enough to be seen through the mask.

"Get packing, we need to leave as soon as possible. The sooner we get back to Konoha, the sooner we can do the eye transplant." Naruto nodded. He wanted to ask Kakashi how he knew so much about the eye transplant, but he already had his suspicions, and didn't feel like prying into his sensei's past.

Naruto stood up and left the room to go pack, while Kakashi just watched the two sleeping ninja.

"I just hope this doesn't make things worse for Naruto..." He sighed as he looked down. He heard movement, and looked up to see Haku sitting up.

"Oh, you're awake."

"W-where am I?" He asked, clearly unnerved.

Kakashi smiled. "You're in the home of bridgebuilder Tazuna. You've been sleeping for a few days now."

Haku looked and saw Zabuza's sword beside him. "W-what's this...?"

Kakashi looked away. "Zabuza's gone. He made me promise to look after you." He explained. Haku looked at him in disbelief. "How...?"

"Gato came, that's how. I'd already done enough damage, he was going to die anyway, but then Gato kicked you. With some taunting and harsh words from my student, Zabuza gave his all to send Gato where he belongs. I figured if you could have nothing else to remember Zabuza, you could have his blade. That sword is famous throughout the great nations, as was it's wielder. Perhaps that legacy will live on in you." Kakashi said swiftly.

Haku just looked at him, then at Sasuke. Before Haku even opened his mouth to speak, Kakashi explained.

"He's dying, he doesn't have much time left. Only an actual medic corps team could save him now, and we're too far away from the Land of Fire to make it in time. He's got less than a week, probably at most three days." Haku looked away as Kakashi explained without even a hint of anger or sadness.

"I see..." Haku said quietly.

Kakashi quickly pulled out his book and began to read. "Haku, was it? You should get some more rest, we'll be leaving soon." Haku looked up at Kakashi with confusion.

"You're coming with us to Konoha. I promised Zabuza I'd look after you. You did no major harm to my team, and you have no record, or mention in any Bingo Books. I believe the Hokage will allow it." He explained.

Haku just nodded and laid back down, closing his eyes and allowing sleep to envelope him once more.

The next morning erupted in chaos. Naruto had barged into the room and Sakura was screaming, while Kakashi just looked away. Haku looked over towards Sakura to figure out what was going on, then he saw...

Sasuke had passed on in his sleep the previous night. His face was paler than ever before, and Kakashi had checked when he woke up: The Uchiha had no pulse. Sasuke Uchiha was dead, and it was partly his fault. The guilt of seeing what he had helped cause panged his heart as he watched Sakura Haruno crying and hugging his body.

"S-Sasuke...Come back to me!" She wailed.

As Naruto grew closer and knelt down to Sasuke's body, Sakura hissed.

"Back off, Idiot! This is your fault to begin with!" And she bolted out of the room, and then Haku and Kakashi saw what they never thought they would see: Tears on the face of Naruto Uzumaki. Perhaps it was Sakura's harsh reproach, perhaps it was seeing that his closest friend and greatest rival was dead and he felt guilt, or perhaps it was both, but Naruto was crying.

Kakashi stood up and stormed out of the room, leaving Haku and Naruto with Sasuke's body. Haku felt he needed to comfort Naruto and looked at him.

"I'm sorry..." He said genuinely. Naruto didn't respond at first, but about three minutes later he looked at Haku with sadness in his eyes.

"...Thank you."

Kakashi had just about had his fill of Sakura's behavior. The girl clearly had a lot to learn, and a monstrous attitude that was quite unbefitting of a Kunoichi.

He found his female student outside of Tazuna's home, looking out at the ocean. Kakashi glared at her and snapped.

"You better get your ass in gear, Sakura." He said coldly.

Sakura looked at him in shock and anger. "Leave me alone."

Kakashi walked over to her and pulled her to stand up. "I'm your sensei, so you better listen to me. I'm tired of this damn fangirl obsession you have with Sasuke Uchiha. It's unbefitting of a Kunoichi, and it's damn obnoxious. And Naruto is a member of your team, not an enemy, so don't you dare treat him like one. Sasuke died to protect Naruto, that is true, but how about you look at it as more than just loosing your precious eye candy? Did you even think about WHY Sasuke did it? He did it to help a comrade. He should be honored for such. He was KIA, that is true, and he died honorably doing so. Remember what I told you in your training exorcise. Those who don't follow orders are scum, those who abandon their friends are worse than scum. Sasuke was better than you in more ways than one. He died to help a friend, and you spit on that by blaming Sasuke's death on him. You're disrespecting Sasuke, and telling him his death was pointless in doing so. Get it together Sakura." With that, Kakashi left, leaving Sakura to sit and think as she watched the ocean.

The rest of the day was quite uneventful. Naruto was mostly silent, and Sakura didn't move from her spot all day, nor all night, as Kakashi's words echoed in her mind.

The next day they set out, Kakashi taking the role of holding the valuable cargo they carried: The eyes of Sasuke Uchiha. Being placed in a ice filled case, they would be preserved until they returned to Konoha, where Naruto would undergo surgery to have his eyes replaced with Sasuke's.

Naruto and Haku took the role of making sure Sasuke's body was brought back safely, he would have a proper burial in Konoha, and would be named as a hero.

The trip itself was peaceful, that much was a relief, it was the return to Konoha that was a problem, and Kakashi knew it would be.

Once they had re-entered Konoha's gates, people began to stare as they saw Naruto Uzumaki, the most cheerful boy in the world, silent and grim, with Haku behind him as they carried a stretcher that had a white sheet on it.

Ino Yamanaka was the first to react, leaving the flower shop as soon as she saw that Sasuke was missing. When she realized that, she immediatly ran up and slapped Naruto, demanding to know what he did to Sasuke. Before he could even answer, and before anyone could even move, Ino was sent flying back several feet, blood pooling from her now broken nose. People then turned to see Sakura Haruno with her fist out, and tears pouring down her face.

"Shut it, Ino-Pig. If you ever badmouth one of my teammates again, I'll make you regret it." Ino flipped and was ready to attempt to beat Sakura down right then and there, but she was pulled back by her own teammates, and then her own sensei stepped in front of her.

"Enough, Ino." Asuma stated bluntly. Ino immediatly backed away, and they continued in towards the hospital.

Several days later, Sasuke Uchiha's funeral was held. All attended, Naruto, Sakura, Haku, and Kakashi at the forefront. As the service ended, and all lined up to pay their last respects to the Uchiha before he was laid to rest, crying could be heard throughout the assembled. Some of it was friends, colleagues, and some were just fangirls who wanted to know why he had to leave them behind. Naruto went first, he wanted to pay his respects and leave before Sasuke's fangirls appeared. He looked at Sasuke's pale body in the evening moon, and smiled lightly.

"I promise, Sasuke, I'll fulfill your vengeance." He said quietly. From there, he dropped a flower, and left swiftly.

Some days later, Kakashi stood at the memorial stone, looking at a single name that was carved in, 'Obito Uchiha'.

"What're you doing out here? Lord Hokage wanted to see you." A soft voice asked the jounin. Kakashi smiled as Naruto walked over and stood beside him, gazing at the newest name on the stone, 'Sasuke Uchiha'.

"Just talking to an old friend. And you? The same?" Kakashi asked.

Naruto just continued to gaze at the stone, and his pale blue eyes turned to the blood red gaze of the Sharingan eye.

"Yeah, I guess you could say that."
