10.6K readers?! YAY! I didn't think I would get this many. To be honest, I was doing this for fun but now I'm serious about it. And besides, I do my best work when it's 2am and I'm dead tired but can't sleep. *says while downing a pot of coffee* Now for review responses.

Bankai777: I'm sorry I can't do that. But if you want to see him get his ass kicked, I can assure you, he will suffer.

Monster King: Thank you. Will do.

OtsutsukiMadara: Sorry about that. I could lie and say that he was trying to make a point but actually, it was a slip of the fingers. I should have said Orochimaru or something. Feel free to reread the last chapter and replace tailed beasts with Orochimaru.

VPSnale: Oops. I didn't mean to do that at first but now it's too Kakashi-centric to be fixable. The summary will be changed. I'm sorry if this upsets you.

New summary: For over a thousand years, remnant has had more than enough dust. But when they start to run out, they turn to other places. Like the Elemental Nations. But they found nothing and instead of leaving, captured the innocent citizens of Sea Country and used slave labour. And thus the 5th Shinobi World War began. 6th Hokage Kakashi. Teacher Kakashi. Godlike Kakashi within reason. OOC Kakashi.

Dr. Oobleck was spewing out random thoughts about the first great war. About how general (someone) was young and dumb and made the mistake of ambushing the faunus in their sleep. In the end, they were caught off guard and slaughtered. It wasn't until he started talking about the Second Great War that people started to pay attention.

"Now. Can anyone explain to me how and why the Second Great War Started?"

A random student responded. But he seemed to be one of the smarter ones.

"Because Atlas and Vacuo decided to look for more dust on an unexplored continent. And when they found nothing, they committed unspeakable crimes and forced the people of Remnant into a war we clearly were not prepared for."

'Well, well, well. This kid is a lot smarter than I thought. And it appears that some of these people might actually make it as a shinobi. But now is not the time. I will ask them when it's my turn to teach them. The life of a shinobi has more advantages anyway.'

"That is correct Jonson. Extra credit! Who can tell me the parts one or two of The Battle of Mallasterinera?"

Kakashi raised his hand.

'Of course he did. He was the one who led the attack after all.'

"Ah. Kakashi Hatake. How nice of you to participate. What can you tell me about part one of the Battle of Mallasterinera?"

"Well Dr. Oobleck. I can tell you a lot of things. Considering I was the one who led the attack. Anyway, after hearing about a major airbase in the mountains of Tea Country, we knew that that place would cause major problems if left unchecked. So after leading our best pilots into battle, we made sure to deal with the airplanes first. Pay attention kids. This is tactics 101. Though we lost 10 fighters and 6 men, it wasn't enough to stop us. We went after the high-value target first. The hanger bay, control room, barax, supply station, the whole nine yards first. Of course, even 30 pilots weren't enough to do all of that in 4 hours.

So that's where myself and the ANBU came in. Though I give you credit for not leaving your ground unguarded, you should have sent more men. No offense Dr. Oobleck."

"None taken."

He was being honest. He despised that war and after the 1st major battle, and knew exactly how it would turn out.

"It wasn't long before the attack was over and we let the survivors flee. As to why we did that, well, you'll have to figure that out on your own."

"Impressive Lord Hokage. That's quite the tale and with official reports to back it up. Although, 4 hours seems a little slow."

A playful taunt. Kakashi would play along. After the doctor did a caffeine enhanced zoom towards the bottom left corner of the room, he used his real speed to meet Kakashi in the middle with his weapon deadlocked with Kakashi's kunai. Everyone tensed. But relaxed when both of them laughed in respect.

"Dr. Bartholomew Oobleck. If you ever decide to become a ninja for any village, hit us up. I promise you, you'll love it. We could use men like you. Now I believe class is over."

"You're damn right it is. Now out! All of you! Report to the combat room tomorrow for 1st period, fully dressed.

With RWBY the next day

"We don't have combat class today so why are we having one? Schedule change, maybe?"

"No idea Ruby. Let's get dressed. I can't wait to blow off some steam."

Everyone sighed. She needs to learn to let go. It's that kind of attitude that starts wars. Grabbing their weapons and gear, they marched on towards the classroom. Where someone they would never expect was waiting.

Line break

Kakashi was greeted with widened eyes as no one thought he would be their teacher. Once everyone was accounted for, he started the class.

"Good afternoon everyone. As you know, my name is Kakashi Hatake. You may call me either Lord Hokage or Kakashi-sensei. This is a secondary combat class. Meaning you are not required to take it. But if one person drops out or fails, then the rest of your team will follow. So choose wisely. Also, Professor Goodwitch will teach you how to fight like huntsman and huntresses and use tournament rules. I, however, will only stop the fight if the person's aura breaks or if someone is in danger of crippling injury or death. Of course, if you want to surrender, I won't stop you. One more thing. If you don't stop when I tell you then I'll make you stop."

Everyone shivered at his threat. He said he would make us stop fighting but he didn't say how. Now that was the scary part.

"Now to lay out some ground rules. One. You will show me the respect I have worked for all my life to deserve. Two. When fighting someone in this class, anything goes. In fact, I encourage you to use dirty and underhanded tricks. In this class, you will learn to fight like a shinobi. If you don't like it, then you better be able to convince your team to drop out as well. But for those of you who enjoy it, then be sure to stick around and we'll see if you're better off as a shinobi than a huntsman or huntress. Oh, and one more thing. Those who enjoy my class too much, will find you and your team expelled from my class, by force, if need be. Is?! That?! Clear?!"

No one dared question him. Not even Cardin.

"Now then, any questions?"

Weiss raised her hand.

"Kakashi-sensei? What is our first lesson?"

"Your first lesson is shinobi theory and rules."

(AN: Prepare for a lot of kakashi)

"Rule number 1: There are no rules. In combat you may use any jutsu, technique, style, weapon, and/or object to win.

Rule number 2. Old enough to kill, old enough to sin.

Rule number 3. A shinobi must look underneath, the underneath.

Rule number 4. A shinobi must put the mission first.

Rule number 5. A shinobi must be as prepared as possible.

Rule number 6. Neva let 'em see you sweat.

Rule number 7. Always watch your back,

Rule number 8. Be aware of your surroundings.

Rule number 9. Always be two steps ahead of your enemy.

Rule number 10. The four prohibitions are money, alcohol, drugs,and women. Do and use as you wish but do not let it affect your performance. Unless you have a death wish.

Rule number 11. Assume your enemy has every advantage over you.

Rule number 12. You're a shinobi. You lie, cheat, steal, murder, and survive in the name of your village.

And finally, rule number 13. Those who break the rules are trash. But those who abandon their comrades are worse than trash. Remember that. You would do well to learn that in a classroom instead of on the battlefield like I did. Any questions?"

The class was silent. Even the usually hyper Nora was quiet. And Ruby raised her hand.

"Sensei? What are the requirements to become a shinobi?"

"Well, in order to become a genin, you must enter the academy and pass that exam first. After that, you will be given two other teammates as well as a jonin sensei. However, you must pass his or her test before you are officially shinobi. Otherwise, you're on the reserves list. However, you are only required to be a shinobi for two years before you're allowed to drop out. But know that as a genin, it's your job to get stronger. But don't be afraid to ask your sensei for tips along the way. That being said, you have already been given teams even if they're teams of 4 with a team leader plus one sensei. However, that person is only in charge when the jonin is incapacitated or unable to lead for whatever reason. Next person."

"When do we learn how to fight?"

"Right now if you wish. Any volunteers?"

"I'll go sensei."

Lie Ren was the first. Now this piqued Kakashi's interest. He'd seen his type before and found it very difficult to deal with. But he could respect that. He was a shinobi not a samurai.

"Lie Ren, correct? Your style relies on quick and well placed blows at various places. Not a very heavy hitter. But you know that a trainee can kill a huntsman with one well placed hit. You are almost faster than Ruby who has a speed semblance. Of course, that's without aura. Am I wrong?"

Everyone tensed. How in the hell did this man know so much? Was he bullshitting or was he actually correct.

"No you're not. Though may I inquire how you figured that out. Allies though we may be, I doubt Ozpin would give you access to my file."

"Very good. And I know because you're very lean and can run very fast. I watch the initiation. You would give the ANBU a run for their money in taijutsu better known as hand-to-hand combat. But let's see how you fare against a three time war vet."

Creating a shadow clone proctor, he started the match.

"This is a taijutsu only spar. Boss. You may use that if you wish. Ready? GO!"

The class was in awe as to how Ren was keeping up with Kakashi. He was holding back, of course. After all, this was a spar, not a one-sided beatdown. Every punch and kick thrown by either party was blocked or dodged by the other. And Ren was holding back as well. Getting a feel for his opponent. Smart. Kakashi thought.

"Let's kick this up a notch."

"Yes, sensei."

They vanished at mid-jonin speed, much to kakashi's pleasure.

'This kid's good. Better than the average ANBU. Congratulations Lie Ren. You have earned this.'

In his moment of weakness Ren punched him in the face. Hard.

"FUCKING HELL! That was amazing! You earned this Lie Ren. Prepare yourself. For only the best of the best get to see this. Kakashi activated his 3 tomoed sharingan and charged at Ren at low kage speeds. Ren had to use aura to keep up. The sounds of flesh hitting flesh filled the room as they blocked each other's attacks.

"You only have enough for one last attack so let's finish this."

Ren attacked him at low kage leven Kakashi was too fast. He used his momentum and tossed him into the wall behind him. Breaking his aura but not knocking him out.

"Lie Ren. I'm impressed. You actually made me sweat. A lot actually. You, shadow clone. Take him to the infirmary and tell Ozpin what happened."

He paused and mumbled under his breath.

"And do everything you can to make sure he becomes a shinobi. He is too good to pass up.

Anyway, that's all for today. But remember, if you are absent without good reason, then I will assume you have dropped out. But do not be ashamed and do not make fun of them for it. This life is not for everyone. I would rather see you drop out now than die on a mission you weren't ready for.

Now then, for homework, I want you to come up with at least one attack that requires one or more teammates. Trust me, you'll need it. Class dismissed!"

Everyone left, thinking about what happened.

"I think I'll join him. I think he broke my nose.'

Line break

That was quite the show, Lord Hokage. Even I learned a thing or two from that class. And I must say, giving them an abnormal assignment but not telling them why, bombarding them with philosophy, and dumping them into the morally gray area where good and evil begin to mesh. Those are some interesting teaching methods. Unorthodox though they may be, they can't be ineffective if you're using them. While I know for a fact you will not cause any permanent damage or at least, no pain, no gain, I can't help but wonder. What is your game?"

"You're a smart man Ozpin. But you're right. I have no intention of harming your students beyond simple training pains. I'm doing this because it's good practice if you become a shinobi. When a ninja is given a mission, he does not ask his kage questions. Although, he may ask the client what he or she deems necessary if possible. And to be honest, I'm trying to see who at least has the potential to become a shinobi. And speaking of potential. That boy. Lie Ren. I want him. He's two good to pass up."

"Now, now, Lord Hokage. You know I won't agree to something that easily. So how about a deal. He will be given the choice and neither of us will say anything should he choose the opposite side. Oh and one more thing. As headmaster, I can't do anything about Cardin and his team without proof. But just between soldiers, politicians, and teachers, watch him. His father attended this school a few years ago during the war. He came very close to killing another student and I'm afraid he might do the same. On a better note, come Lord Hokage. I believe they have huntsman class now. Let's see how this goes."

If you could describe Glynda Goodwitch's class in one word, it would be boring. Of course, only boring to those who wanted to be a shinobi. Other than boring, they thought this class was How To Get Yourself and Others Killed 101. But it was good for one thing. Learning how to kill hunters. Not that they would do that without reason, but still.

"Now then, I know there weren't any sparring matches but I promise you, you'll get your fun on Friday."

Kakashi had an idea. A little petty revenge might teach her a lesson. It was Tuesday. Meaning, he had two and a half days to turn his students into passing shinobi. After all, a headlock is a real good way to drain someone's aura.

The next day

The next day, Kakashi's ninja class

"Alright everyone. As you know, the most popular teams RWBY, JNPR and CRDL, the last of which was not invited even though he was part of Oobleck's class."

(Plot hole fix: Ozpin told team CRDL not to attend that class and would be severely punished if they tried)

"Meaning, this class of 24 will learn how to fight like a shinobi. You know the theory. I made sure of that. Now it's time to put it into practice."

Making multiple shadow clones, he proceeds to give instruction.

"Assassination team. That one. Assault teams. That one. Trackers. That one. Sweet talkers. That one. But Lie Ren. You're me. Any shadow clone sent at you will be murdered plain and simple without a clean advantage other than skill and experience. Come soldier. You have achieved greatness but it is wasted at this academy. I suggest you take the final academic exam and I'll get you into the shinobi ranks. This is optional though and I won't be disappointed if you choose to become a huntsman instead. I'm sure Ozpin has given you the same talk, or at least will here soon, with the exact opposite carrier option. You are dismissed and I am going to ask you to leave so you can think about what I said. Know that you are not in trouble. I'm sorry, but life choices should not be decided in split second situations. Now go. You have much to think about."

Line break?

"What is it that I want? As a huntsman, there's a chance I'll be forced to take some mission in the EN that's bound to cause backlash. As a shinobi, I might be forced to do things I'll never forgive myself for. All for the greater good. But I must endure. Such is the way of the shinobi."

He made up his mind. He needed to talk to his team about this.

It wasn't long before Ozpin snuck by everyone and spoke to Kakashi about that promising young man?

"What path do you think he'll choose?"

"I'm sorry Lord Ozpin, but that man is a shinobi through and through. But I promise you this. He will never enter the ANBU, not unless he knows what he's getting into. That path is literally pathed in blood, sweat, and tears. I should know. I spent 60% of the 3rd world war in it. And let me tell you. I saw and spilled enough blood to paint the moon red. No one ever comes out of ANBU perfectly sane.

I ready my smut because it gets my mind off all the horrible things I've done. ANBU Bear has a cross tattooed on his forehead as a memorial to those who died on all sides in all wars. It was a downright tragedy when he died. He was buried in the village and given a headstone in the Hidden Leaf Memorial and what we call the Graveyard. It's on the man-made island off the coast of Wind Country. 40 square miles of sand, dry winds, wooden crosses, precious last items, and/or flowers on the gravesite. Complete with how he died and his last mission."

"You know they won't take that well. You'll show them what happens when thousands of men try to kill each other in bulk. I'll sanction this one one condition. You have Taiyang and Qrow come with you to run damage control if need be."

"I agree to your terms. I will have ANBU to do the same. Good day your highness."

Ozpin sighed.

"And Glynda, you're going with them. You need to let go. People who swear revenge end up becoming worse monsters than the ones they hate. Ask any 4th war survivors."

"When is this 'field trip'?"

"Next Monday."

"I see."

Friday, Kakashi's class

"Sorry I'm late. A black cat crossed my path and I had to take the long way around. Anyway, as you know, Glynda's "combat class" is hosting a tournament and I think it would be funny if we surprised everyone with how well everyone is doing."

Everyone caught on to what he was saying. Even Ruby who is normally dense as a rock. He wanted to scare the shit out the entire school. And get a good grade doing it.

"Assassination squads. Remember, anything goes and you will use my rules, not hers. And if you win, I'll teach you an interrogation tactic. Assault teams. Whatever team wins by the highest margin gets one free meal from yours truly. Trackers. There's a standard set of ninja gear for each of you in my office with your names on it. Win, and it's all yours. Trackers. 20 lien says you beat them in under 5 minutes. And the Sweet Talkers. Win, and you get one free coaching session on shinobi politics. But if everyone wins…"

Kakashi smirked.

"Drinks are on me."

The class roared in approval.

"Class! Form up!"

Ah, a form up. Everyone would get i behind Kakashi and they would walk badassily towards a destination.

"Onwards, my students! Greatness awaits! And so does liquor!"

They cheered even louder and Kakashi used a genjutsu to make it look like they had an official flag.

Glynda's "Combat" Class

"Hello everyone. As you know, today will be our first sparring session. Our first match-up will be ROSE vs STTR. Begin!"

Team ROSE. (You already know who they are). And team STTR. Aka. Sweet talker. Not the strongest team in the class, but better than most. And better yet, they knew the most mathematics and science.

"R. Take out S. O to tall T. S to little T. And E to R."

They nodded and charged in head on.

'Like morons.'

Taking out RO was a little too easy. Red fell when Suesan grabbed his arm and forced him into the ground. Hit him so hard, he lost all his aura and got a dislocated shoulder and was tossed out of bounds. Glynda didn't say anything because it happened to quick for her to follow. Owen tapped out when tall Tim got him in a chokehold. The lack of oxygen sucked up all his aura and he was out like a light in 3 seconds when his aura broke.

Flashback to that fight

Tim from Team STTR was having an easy time. He would have taken his time with this one, but he really wanted those lessons. Doing a baseball slide under him, he popped up behind him and proceeded to squeeze the life out of him.

Green.

Yellow.

Red.

"Timothy Nater! What the hell are you doing! Release him this instant!"

NONE!

And that's all she wrote. The kid was out like a light and in need of medical attention. He would live regardless. It's just a matter of, "Will he wake up feeling tired or will he wake up feeling like he got run over by freight train?" With that, Tim dropped him and kicked him towards the professor.

"I'm winning Professor. Our enemies don't play fair and neither will I. I've decided I want to be a shinobi. Meaning, we lie, cheat, steal, murder, and survive. Deal with it."

Tim, the leader smirked as he watched everyone else quickly dispatch their foes with ruthless efficiency.

"Now guys. I believe Kakashi-sensei owes us a little coaching session in shinobi politics."

End flashback

Glynda grumbled.

"So that's who's responsible for this. Maybe now Ozpin will listen to me. Anyway, the next match up is team RWBY vs team FLOW. And please don't be so ruthless.

(AN: I'll skip this fight. RWBY wins but they fight like huntsmen.)

"Well done team RWBY. Next, Team JNPR vs team BBRY(Blueberry). Good luck."

"Ren. I want you to take this one. We might not be ready but you are. After all…"

He started to raise his voice.

"He's the only one who can give Kakashi-sensei a run for his money in hand to hand! Have it my friend."

He nodded.

"Come Team FLOW. Let us see if you are a worthy opponent."

Hand to hand wasn't the only thing Kakashi taught them. Psychological warfare. Interrogation tactics. How to be a better liar. That's how he did things. A shinobi is prepared.

Floyd and Owl, as he was called, charged right into him. Of course, this was all too convenient for Ren. He used Floyd as a human shield and Owl's sword came crashing down on his head. And a quick headlock was the finishing blow. As in, "you need to go to the infirmary." Finishing blow. Now to finish the rest. He charged right into them and punched Lyman in the gut, then switching to W. He used him as a human shield as well and tossed him at Glynda's feet.

"2 down, 2, to go."

He gave them a visual taunt and they fell for it. Their attack's "landed". Yeah. If hitting the ground and creating a whole bunch of dust, blocking their vision.

"Where is he?!"

"I don't know!"

'Thank the gods for those stealth lessons Kakashi-sensei gave us.'

And they dropped like flies when he smacked their heads together and they fell down, unconscious.

"Call it. They're done."

"Just go back to your seat. You win, we get it. That's all for today. Dismissed!"

Everyone knew there was still a full 30 minutes left of class but no one could handle another one-sided slugout like that. But the potential genin went to see Kakashi.

"Kakashi sensei. We won out matches. But those who didn't fight, won by forfeit. Now fork it over sensei! You owe us!"

Kakashi grumbled at the playful disrespect but was proud nonetheless.

"You're damn right I do. Assassins. I'll get you guys a book on basic interrogation by tonight. Team Dove. You're the lucky winner. Remember guys, a shinobi needs to be lucky. Pick a place and I'll pay. Team TRAK…"

Kakashi grumbled.

"Tell anyone I gambled on you and I will have your head. Now have fun. And the Sweet Talkers. Meet me in my office tomorrow at 7:30. I will be dressed as a kage so you know what that means. Now onto the good part. I hear there's a nice bar in the Red Light District that has nice drinks for a good price. If you want to get laid, have at it, but I ain't payin'. Now onward, my cute little genin! Time to celebrate!"

Kakashi knew this was going to bite him in the ass somehow. Politically? 50:50 chance. The entire staff of Beacon Academy breaking down his door and demanding answers? 100:1 against Kakashi. He'll live. After all, it's not his fault his students can't handle a little alcohol.

And that is chapter 6. Tell me what you think. I'm sorry but I had to make sure Kakashi was a bad influence on everyone who wasn't a shinobi. What will happen when they visit the "Graveyard"? I have a plan but I want to know what you think. Now if you'll excuse me, I have to go make some more coffee.
