Harry Potter had been a mystery to most as soon as he stepped foot in Konoha. It was actually how he had arrived that had people looking at him with suspicion, although materializing in the middle of Konoha's market in its busiest time of day would certainly attract all sorts of attention. The AnBU and many off duty shinobi that were in the area instantly converged on the man with foreign features, but for hours they could not catch him due to their limited capability in jutsu. Harry might not have known where he was or why exactly he was being chased, but staying on the busier streets had never harmed him before except when those chasing him had no qualms about going through the innocents. Eventually, the mysterious man found his way into the Hokage's office moments before the man was going to get involved. The search was called off only moments later and while no one knew what had been spoken about, Harry Potter was soon considered a fixture in Konoha's many faces.

"Ah, Harry, so good of you to come. And on time to," Hiruzen noted as his mind went to one silver haired jonin. It had been three years since the great chase that had put all of the Great Naruto chases to shame. In those three years, Harry Potter was still considered a mystery, but with his special skills that most thought were just another bloodline, he had been able to cure diseases that were once though incurable and was able to give many shinobi longer careers. He was also responsible for discovering a handful of sleeper agents from various countries and was able to give some of the more hardened shinobi a run for their money.

"Of course Hiruzen," Harry replied, his emerald eyes looking around what was quickly becoming a familiar office. He didn't know what made him so special, but he seemed to easily make friends with those in power and were one of the few that could use their first name without any problems. "I would have sent word if I was in the middle of something, like my potions or tonics." Harry had rediscovered his love for potions that had been ruthlessly squashed by Snape when he didn't have an overbearing bat hovering over him.

"So let's cut straight to business shall we? I am in need of a teacher and you once mentioned that you were able to lead your classmates and even some older than you in your defense class, correct?"

"Yes," Harry replied tentatively. In truth he had loved leading the DA and was not opposed to teaching once again, but he was far from the naïve teenager that had been roped into doing it by his best friend. He wanted all the facts first.

"There was an incident last night that involved a handful of chunin's including the current instructors for next year's graduating class. Even though I could order another chunin to take over, you and I both know that it takes a special temperament to teach." Harry nodded in agreement as images of Snape an Umbridge sprang to mind. In truth, most of the teachers in Hogwarts weren't good teachers, but the best that Britain had to offer. "I had hoped that with your experience and enjoyment in teaching that I could convince you to take over the class for at least the remainder of the year."

"There's something more isn't there?" Harry asked pointedly, noticing that Hiruzen was more tense than usual as he leaned over his desk. "Who is in the class that could be such a problem because I know it isn't Konohamaru."

"There are eight clan heirs in the class that you will be taking over as well as Naruto. I understand it was a time for celebration at the end of the third war, but it has made having an unbiased teacher for that class very difficult. With Naruto's burden and Sasuke's status as the last Uchiha, it's been damn near impossible," The Hokage spat. Harry was well aware of Naruto's burden due to a bit of drunk talking from the older shinobi and some mind reading. "I know you don't care about clan politics or the Kyubi and are the least impartial teacher I could find."

"So, let me get this straight. You want me to teach a bunch of kids what it means to be a shinobi for at least half a year, a year and a half if you can convince me I'm sure, all because I'm not biased?" There was a brief pause before he continued, "You do realize I'm not a part of your forces right? Hell, I can barely produce enough chakra to tree and water walk as it is!"

"I know this Harry," Hiruzen pointed out, "But the only other shinobi that I could ask at the moment that could be potentially unbiased is Anko." Harry shivered at the mention of the crazy and sadistic snake lady. They had met rather early in Harry's stay in Konoha and her fascination with snakes had caused him to have flashbacks to the war. They were friends now, but it hadn't been a comfortable experience as they got to know each other. "I'm sure you don't want impressionable children to be introduced to her so soon. As far as being a shinobi, the elders agree with me that with your bloodline you more than make up for the lack of chakra."

"You need to work on your shinobi Hiruzen," Harry delivered with an expressionless tone.

The Third Hokage chuckled, "I'll get right on that Harry, but does this mean you accept my offer?"

In truth, Harry could see no reason to not accept his new position. Harry found himself bored with a simple life of making potions for various shinobi departments and experimenting with seals, of which he had a knack for. He had enjoyed teaching the DA and found himself getting excited at the prospect of teaching once again. That wasn't to say he wasn't going to make Hiruzen sweat a bit, his marauder heritage practically screamed at him to do so.

After a few moments, Harry took pity on the old man. "Fine Hiruzen, I'll take over as teacher for the remainder of this year at least. There are a few conditions that need to be met though."

"Of course Harry," Hiruzen sighed in relief. He knew the young man wouldn't ask for anything too outrageous and it would probably be a benefit to the class if he asked for it.

"One, you need to look for a helper or two for me while teaching. I can teach the class no problem, but there is no way I can divide me attention equally amongst the twenty-seven or more students that I will be in charge of and have them all at the same level in class." Hiruzen nodded and jotted down a note for the reasonable request. "And secondly, I need to be able to make changes to the lesson plans as I see fit. With how much your jonin sensei moan about the rather weak level of new genin, something has to be wrong with the curriculum."

"Reasonable requests Harry, if you have a moment now, I can have someone fetch the lesson plans of your predecessors and we can see what needs to be changed." For much of the next hour, the two men went over lesson plans for the future generation.

-Sensei Potter-

There was a bit of excitement in the students as they waited in class Monday morning. After almost a full week of substitutes that changed every day, they were getting their new permanent teacher for at least this year. Some of course saw the academy as a waste of time and an obstacle to their goals, but each was ready to meet this new teacher. One Naruto Uzumaki was particularly excited with a foxy grin on his face as he thought of all the pranks that he could pull on this new and unsuspecting new teacher.

As the door opened everyone's attention was focused on the figure slowly walking through the door. When Harry came into full view of the class, it was as if a switch was thrown and all of the clan kids sat up a bit straighter. Everyone knew of the strange rumors about the mysterious arrival that had managed to evade some of Konoha's best before being eagerly accepted into the village. He also seemed to have a healthy relationship with all of the clan heads without being one himself, so the man in front of them seemed to demand respect.

Harry Potter was dressed in the standard Jonin uniform, his status having been officially declared as a special jonin, with a black jacket that reached the floor. His green eyes shone brightly as he swept across his students, no longer needing glasses because the pressure of the horcrux was no more. A faint outline of a lightning bolt was spotted on his forehead since Harry had kept his bangs in the same style as he had in Hogwarts, though he had let the back grow out enough for a small ponytail.

Harry held back a chuckle as he noticed the attention that he was being giving by the wannabe ninja warriors at the moment. With a casual wave of his hand, the pranks that had been set up were dismantled and would be no issue to him. It wasn't a bad set up in truth, but as a second generation marauder the young Naruto would have to get up much earlier to get him with his pants down.

"Good morning class," He started as he casually leaned back on his desk, "For those of you that don't know me, I am Harry Potter and for the foreseeable future I will be your sensei. I don't care if you use my first or last name or even stick with just sensei, but I do expect your respect. If you are going to curse my name, and I plan on getting you to that point quite often, you will do it out of earshot." Harry received a few appreciative chuckles that caused him to grin a bit.

"Everything I teach you in this class is going to help you survive when you start your shinobi careers from simple mathematics, to kunai sharpening, to various plant life. All of this is important so," With a flick of his wrist he sent two pieces of chalk flying towards Kiba and Naruto, "You all need to pay attention." Harry received a few more appreciative chuckles and a pair of rueful grins for his efforts. "I have discussed my lesson plans with Lord Hokage and we have decided that this class will serve as a test for the rest of the academy and future classes meaning it will be tougher. Not one of you needs to plan on graduating early."

Seeing that he had their attention, Harry decided it was time to move on to the next subject which garnered a collective groan. "Now, it is time for a pop quiz. This won't be graded and it will be given orally, but I need to know where you all are at before we can move forward. Since this is my first day with you just as it is your first day with me, when I call on you I want you to give me your name and future career path. I don't care if it's what type of ninja you want to be, what position you want to hold, or what type of skills you will focus on, but please for the sake of time limit it to three different things." Seeing that the class understood, Harry started the pop quiz. "First question: Who were the founding clans of Konoha? You miss…" He pointed towards the Yamanka heiress. He knew who each of his students were due to their parents, but it was nice to get to know someone without barriers in-between.

"Ino Yamanka sensei," Ino said standing up. "I want to follow daddy into the T&I department and if I get a sensei that knows their stuff, then I'd like to be a poison specialist." This didn't surprise Harry in the least as the Yamanaka's did own a flower shop, so she was already predisposed to that type of specialty. "The founding clan members were Senju and Uchiha," At this, almost every preteen girl looked towards Sasuke and sighed fondly. Harry was slightly disturbed as he had flashbacks to his own days of fangirls and felt sorry for the poor boy.

"Very good, now, who can tell me who was able to destroy our allies, the Uzumaki? You the pink haired girl next to Ino."

"I'm Sakura Haruno sensei and I, um, I really don't know what I want to do with my shinobi career," She admitted with a small blush.

"Civilian born?" Harry asked with a bit of understanding. "Not to worry as this was partly the reason I wanted everyone to tell me their plans. I'm sure that you will change your minds half a dozen times before you reach chunin rank, so there is no rush, but there is also no reason to not think about it. I plan on introducing a few guest speakers soon that have experience in the various fields found around the village. Go on and answer the question."

"The home of the Uzumaki's were laid siege to by Kumo, Iwa, and some forces from Kiri. A force of almost a thousand shinobi were lost before the third war as it took almost that entire amount to wipe out the seal masters of the clan."

"Textbook answer, but a little more than I asked for," Harry pointed out making the girl blush and duck her head. "There's nothing wrong with that, but if you do go on to be a shinobi know that your life is measured in seconds. If it is important speak up, if it is some trivial information make sure you are safe before divulging it."

Sakura gave a weak nod to her sensei with her eyes a bit downcast. Harry noticed that the rest of the class also had their heads down and he mentally slapped himself. The last time he had taught it had been with a group of teenagers that for the most part knew what they were getting into and knew that a war was on the horizon. The students in front of him were under the age of twelve and had only recently begun their work towards their future career paths. Shinobi children developed mentally at a prolific rate, but they were still children.

"Look," Harry spoke up, getting the attention of all his students, "You all have decided to become soldiers and serve your country to the best of your ability and I commend you, but you need to realize just what that means. I am not trying to scare you off, but I refuse to let anyone of you to pledge yourself to a life that you may find unsavory. I will not speak about it now and if I am correct I'm really supposed to let your jonin sensei teach you this, but I find it a disservice to you all. I see all of you surpassing all that came before you, but you have a long way to go and a lot of power to accumulate before you reach that point. A saying from my home used to cry Knowledge is Power and I am a firm believer in this. I shall arm you with as much power as I am able."

He knew he had his class hooked on his words, though each seemed to be focused for different reasons. Using a little passive mind reading, which Harry and Inochi had discovered was rather different from the Yamanaka's mind walking technique. Snape would have had a conniption as the Yamanaka's were able to read memories much like a book, though their techniques were nothing but noticeable. While Harry didn't have much skill with legilimency, what skill he did have was almost undetectable. It was only the skilled jonin that could even sense his intrusion.

For the most part, Harry was happy with what he detected, but Sasuke worried him. There was a spike of anger at the word power and an almost vengeful need to gain as much as he could. Harry knew the story of the Uchiha clan and he also knew that there was no way to get Sasuke removed from the shinobi program, but that didn't mean he would let a mentally unstable individual out as a genin. He had met plenty of jonin that had developed specific quirks, but all of them had developed the maturity and discipline needed to not harm their comrades. He would need to talk to a few psychologists to get a feel for how to deal with the last Uchiha.

Questions continued to flow and each child was called upon at least once so Harry knew that they at least were paying attention. Finally, Harry moved to his final question and chose Naruto to answer. He could see the blonde visibly deflate as attention was finally given to him.

"Um, I don't know sensei," Naruto slightly stuttered and the boy seemed to be waiting to be kicked out of the class.

Harry hummed while looking at the Kyubi container. "Let me see your books Naruto, this should have been in the first two chapters." Instantly, Harry knew exactly why Naruto did not know the answer as the books were complete and utter crap that was outdated by at least a decade. Harry let the class know as well and came down hard on those that snickered. "Naruto, you will receive your new books tomorrow and I expect a few of you to help your classmate catch up. I would like to remind you all that everyone in this class has the potential to be your teammate in a year and a half. These will be the people you rely on to keep you alive. You may find it funny to laugh at those struggling, but I want you to think about the future."

Harry knew that not all the children would be able to move past their views and almost none would be able to do so in a day, but those acquaintances of his may end up becoming lifelong friends. He saw so much of himself in both Naruto and Sasuke that he would do everything in his power to help them on their path.

A/N: Not much change in this chapter, but I didn't want to completely change the story. Basically, I have removed the harem, the last installation was simply meant to see how I felt writing the subject and I have decided to remove it. I don't want to deal with any relations until Naruto and his friend graduate either. I'm looking through the reviews and suggestions for lessons and if you have any ideas feel free to leave them. I will try to update at least once a week until I'm caught up with where I was.
