And thus the attack on the hidden leaf village had begun as a bunch of sound ninja storm the whole area, further interrupting Gaara and Lee's fight.

Gaara looked mad. "Your all gonna suffer for this interruption!"

Trunks began to get innocent bystanders to safety as Orochimaru battled against the hokage.

Ino looked over at Trunks. "Help us!"

Trunks smiled. "I will, my lady."

Ino blushed. "Um, okay... thank you."

Trunks ran up and punched Gaara down unconscious. "Sorry kid, but your fight is over."

Kakashi smirked. "Thank you for the help! Get outside now and don't let the old hokage die!"

Trunks nodded. "I'll save him!"

Hinata then pointed up, seeing Tsunade arrive with a bunch of ninja. "Everyone out!" Tsunade yelled.

Lee then tried to get away from all the sand Gaara was attacking him with until Kakashi blasted Gaara away with the Lightning Blade, as then Kakashi grabs Naruto and escapes the attack.

"Haku, follow Kakashi and make sure you two and that blonde kid get out alive. I'm going for the snake guy." Zabuza said. You see, because Naruto was gone, Kakashi had taken only Sasuke and Sakura on their first mission together when they encountered Zabuza and Haku.

Flashback (There will be a lot of these) -

As Team 7 came to the land of waves, two assassin's named Haku and Zabuza were ordered to kill a bridge builder. As Haku met Sasuke before their battle, Sasuke said, "What do you want with me? I can't remember my past, so their is nothing to talk about... I should get back to my friends." Sasuke said as he met Haku in a forest.

Haku smiled. "I wish I could forget my past too. It was hard for me to live with an assassin."

Sasuke drew his kunai. "So your with Zabuza then? You've come to kill me, haven't you!?" Sasuke asked as he attempted to attack her.

Haku smiled. "No... I wish you no harm... do you have family?" Haku asked.

"F-Family... I do..." Sasuke said as he began to remember his life. "Itachi..."

Haku smiled. "Is Itachi a relative?" Haku asked.

"Shut up! I hate my brother!!!" Sasuke yelled as he remembered everything about how his brother killed his family.

Haku smirked. "You and I are not so different... tell me, what is your goal in life?" Haku asked.

"To kill Itachi Uchiha!" Sasuke yelled.

Haku gasped in terror. "You'd kill your own brother?"

Sasuke nodded. "I want him dead! He deserves to die! What would you know about that anyway!"

Haku looked shocked. "It's like if I were to want to kill Zabuza for making me who I am today. Well I won't do that and I'll stop you! Nobody has to die today. Just go home." Haku said.

Sasuke chuckled. "Your clearly a woman, so you don't understand the pain we men feel when we get betrayed."

Haku chuckled. "I dress as a woman for Zabuza. I've made up my mind, instead of killing you, I'll follow you until I can change your mind about killing your brother Itachi." Haku said as she decided to join Sasuke.

"Fine, but that will never happen." Sasuke replied.

Then Kakashi battled Zabuza and his water prison and won. As Kakashi had his kunai ready to slice off Zabuza's head, Haku walked over with Sasuke.

"No more fighting! Zabuza please listen to me, we can be better off working with the hidden leaf village! Stop all of this..." Haku said.

"Always the peacemaker. Fine, if Kakashi spares my life, I'll retreat with you and we'll talk about it." Zabuza said.

Haku smiled in joy. "Thank you, Zabuza."

Then Kakashi, Sasuke and Sakura defeated Gato, and managed to get the bridge builder to safety.

Then they returned to the leaf village, where the old hokage was talking with Tsunade about something important.

"I'm happy to see you again, Lady Tsunade. But if your here, then has pervy sage come with you too?" The old hokage asked.

Tsunade nodded. "You know he doesn't like to be called like that. We came back after we heard that Naruto went missing. It would be heartless of me not to come back, considering Naruto is my family." Tsunade said as she saw Kakashi walking in. "Kakashi... it's been a long time... your looking healthy as usual." Tsunade said as she remembered their childhood together.

Kakashi smiled. "We completed our first mission successfully."

The old Hokage smiled. "Good. Have you found Naruto yet?" He asked.

Kakashi sighed. "Trunks still hasn't said a word."

Tsunade looked sad at hearing that Naruto was still missing. "Who is this Trunks you speak of?" Tsunade asked.

Kakashi sighed. "It's a long story. Come with me, I'll introduce you to him." Kakashi said as he left with Tsunade.

And then from that point on, Haku and Zabuza came to live in the hidden leaf village, but more on that later.

To be continued.

A/N: I hope the wait was worth it! Yay, Haku survived! I always loved her (his) character design.
