Okay, there is a little time skip because the first chapter was just introducing everything in the story, hence the title 'Introduction'.

On with the show... err... fic?

Three years later, the Hokage had summoned team seven, which consisted of a jounin sensei; Hatake Kakashi, and three genins; Haruno Sakura, Uchiha Sasuke and Tatsumaki Kasa.

Sakura wore a red zip dress which reached her knees and had two slits on either side of the bottom of the dress. Underneath, she wore a pair of short black leggings, along with a pair of blue shinobi sandals and her hitai-ite, which she used as a head band to keep her hair out of her eyes. Her hair was bubblegum pink and reached half-way down her back and her eyes were the shade of green.

Sasuke wore a blue turtle-neck t-shirt which had the Uchiha clan crest on the back, a pair of white knee-length shorts, blue shinobi sandals and his hitai-ite was on his forehead. He had white guards reaching from his wrists to his elbows on both arms and also on his shins. His hair was dark blue, almost black and his eyes were that of onyx.

Kasa wore a dark red t-shirt accompanied by a black waistcoat and he wore a pair of three-quarter-lengths which were the colour of khaki. His shinobi sandals were not blue, but black and so was the cloth on his hitai-ite which was strapped around his right arm. His hair was platinum blond with a single blue streak in the middle going from back to front. His hair was only about an inch long and his eyes were blue, matching the streak in his hair.

Kakashi wore the standard jounin wardrobe, consisting of; an indigo pair of cargo pants with a matching jacket along with the green vest which had numerous pockets on for scrolls, weapons and the sort. He wore a face mask which had a matching colour to his pants and jacket, and it covered the bottom half of his face, ending at his nose. His hitai-ite was on his forehead but slanted down over his left eye, and his hair was silver and stood up high, defying gravity and his eye (only one is visible) was black.

"Team seven, I have another D-ranked mission for you…" The third began but was quickly interrupted.

"Another D-rank?! Can't we do something a bit more challenging, I mean, D-ranks aren't even proper missions, they're just extra chores. Come on, we're ninjas." Kasa complained in his usual irritated voice.

Iruka's head turned bright red out of anger until he exploded, "You Idiot! You're just rookies! Everyone starts off with the simple duties and works their way up!"

"But, but…"

"Kasa, it seems I have to explain to you what these missions are all about. Listen, every day the village receives numerous requests; from babysitting to assassination. Each request is written down on these lists and divided into an A, B, C, D ranking based on their difficulty. The village is also divided based on skill. From me down to jounins, chuunins and genins. The missions are then handed out by us at the top of the ninjas based on their abilities and if the duty is completed successfully, we receive payment from the client. You guys just recently became genin. D-rank missions are perfectly suited for you." The third finished. He then looked up to see that the team was not concentrating on the lecture which he was giving them. "Listen!"

Everyone looked up instantly and Kakashi just put a hand behind his head, showing that he was embarrassed by his team's actions. "I… I apologise…" Kakashi stuttered.

"Geez! All you ever do is give lectures like that. But you know what?! We're ready for anything so just throw whatever you got at us, we can take it!" Kasa said as he gave the third a peace sign whilst standing on his legs which were the same distance apart as his shoulders. His two teammates both nodded their heads at their teammates' declaration.

"Okay, I understand. If you want it that much, I'll give you a C-ranked mission. It's the protection of a certain individual."

"Really?! Who, who?! A noble lord? Or, or a princess?"

"Calm down, I'm about to introduce him… Will you come in here?" Everyone turned around to face the door as it opened. There, on the other side, stood a tall man, somewhere in his late fifties, with a large bottle of sake in his hand, half empty.

"What's this, they're a bunch of brats, especially the one with the funny-looking hair. I mean come on, that blue streak can't be natural. Are you really a ninja, hey?"

Kasa's face began to turn a deep shade of red. "I'll kill you!" He was about to jump at their client.

But he was stopped by his sensei. "What's the point of killing the person we're supposed to protect? Idiot!"

Their client then introduced himself, "I am the amazing bridge construction expert; Tazuna. I expect you to provide me with excellent protection until I get back to my country and complete the bridge."

"Grr… fine!" Kasa exclaimed in his 'I'm-not-happy-with-this-but-I-guess-I-have-no-choice' voice. The third just smirked at the comment before he dismissed them all.

An hour later, the team had packed their necessities and had now begun their mission to the wave country. They all walked quietly together, Sakura in the front, Sasuke on Tazuna's left and Kasa on his right whilst Kakashi was at the back reading his beloved book. Everything was going fine, the sun was shining and there wasn't a single cloud in the sky. Birds were singing from the trees and everything seemed normal to everyone, everyone, except Kakashi, who had noticed a puddle on the path. It hadn't rained in days and each day had been a hot one, so there was no reason for there being a puddle, let alone one of that size. So he was now on guard, though he didn't show, he didn't want to worry his team. So he carried on reading his book, keeping his senses on high alert for anything.

Not soon afterwards, two shinobis had jumped out of the puddle and attacked team seven. They were wearing the same wardrobe, consisting of; a large, thick, black cloak, black pants, black gas-mask-like masks and they both had a large, sharp metal claw on a hand which had been dipped into poison. The two of them ran at full speed towards Kakashi, claws drawn and a long spiky chain held between them. They quickly made it two and had him, knotted, with the chain, pulling it until Kakashi had been ripped into multiple pieces. Sakura screamed a note so high that only dogs could here it. Kasa was stuck to the ground out of sheer shock at what had just happened to their sensei. Sasuke, however, was quick to realise that he had to do something in order to complete their mission. He quickly drew a kunai and a shurikan and threw the shurikan as soon as there was an opening, catching it in the chain, nailing it to a nearby tree. He then threw the kunai which lodged the shurikan stuck. The smaller of the two foreign shinobi was enraged and let go of his side of the chain, the other soon followed the action. One went running towards Kasa to attack, whilst the other ran towards Tazuna, who was open, nothing in between the two. Sakura saw this and hesitated before deciding on what to do; she jumped over to Tazuna, so that she would take the blow, cramming her eyes shut, waiting for the pain which was to come. But she felt none, so she opened one eye, to see that the shinobi had stopped just a mere few inches from her, his eyes bulging out slightly. She then noticed the last person she would expect, holding his arm around the shinobi, it was their sensei, Kakashi. She then noticed that he also had the other shinobi in a headlock with his other arm, limiting the amount of oxygen which they were getting, making them loose consciousness. She had a huge smile plastered on her face but what she saw next turned her smile upside down. Kasa was kneeling on the ground, clutching his right hand close to his chest.

"Kasa! What happened to you?" Sakura screamed, but in a more normal pitch unlike her earlier scream.

"…" No reply.

"Kasa, those claws were covered in poison, we need to get it out by releasing some of your blood, otherwise it will go through your blood circularity system and it will start to take affect." Kakashi stated, with some concern in his voice. After tying up his two unconscious captives, he walked over to Kasa to examine the wound. He took Kasa's hand in his and said, "This is going to hurt, so brace yourself." Kasa nodded and squinted his eyes tightly together waiting for the oncoming pain. Kakashi drew a kunai and stabbed the hand, releasing a large, yet safe amount of blood. There came a groan from Kasa's mouth, teeth clenched. Kakashi then bandaged the wound and said, "It's your choice if we carry on with this mission, even though it is at least a B-rank know, which reminds me, Tazuna, you have some explaining to do." Tazuna grimaced at that. "So Kasa…?"

"I say we carry on. I'm not going back now!" Kasa declared, giving his infamous peace sign. Sakura sweatdropped but was still worried for her teammate.

"Are you sure Kasa?"

"Am I ever not sure, Sakura?"

"Hn… I guess not." Sakura said, mimicking Sasuke's usual single word reply, but with a few extra words. So the five of them carried on walking in the same order in which they were in before the attack had happened. They had another three days of traveling before they would reach their destination.

Back with Zabuza…

Zabuza was sitting on a couch which was curved, allowing about eight people his size to sit on it. He was polishing his sword when in came his two 'weapons'. The two of them walked over to him, side by side, and stood still when they were only just out of reach of his sword.

"Well…?"

"It seems that the demon brothers were no match for the team guarding Tazuna…" Naruto began, only to be finished by Haku.

"…Also that their jounin is none other then Hatake Kakashi, otherwise known as Sharingan Kakashi."

"I see, but I guess that Gatou will be sending one of his other hired teams to go get them before he lets us go and have some fun."

"He already has sent another team, and they should be meeting them soon." Naruto replied.

Zabuza let out a little chuckle, "Figures… We'll have about a week before we'll get our chance… so, why don't you two go and do what you want until then…"

"Thanks, otou-san." The two said in unison before leaving out through the door which they came.

Okay... that's it for this chapter...
