Kenshiro knew something was very wrong the moment he chose to wake up.

In fact, he knew something was wrong when he felt just how warm and comfortable he was. It felt like he was in a expensive bed with feathered pillows and a thick blanket.

But that couldn't be right. He was sure that he had fallen asleep in the middle of a waste land, with nothing but the bare ground to sleep on.

Perhaps someone thought him unconscious and chose to move him to their abode. However, Kenshiro discarded that thought. There was no way someone could do that. His training in Hokuto Shin Ken insured that no one caught him by surprise when he was asleep. He would awaken before they could so much as see him.

Then how?

While he was thinking about this, his thoughts drifted to an unusual dream he had just had.

He seemed to be standing up in the Heavens, with the stars passing all around him within an inky void. His eyes could see nothing else. However, a voice beckoned to him.

It was a woman's voice...deep...forlorn...burdened.

Before he knew what he was doing, he was already making his way around this strange world in an attempt to find the source of this voice. Perhaps someone was in distress and was in need of assistance.

He soon found himself staring a wide door, adorned in pearl and crystal with all sorts of clockwork surrounding it. The very dimension around him seemed unstable here. The world was shifting in a variety of colors. It nearly made him nauseous.

Step through this door Fist of the North Star. You're now our only ray of hope.

The door soon opened and a blinding light cast forth from it. Before Kenshiro knew it, he found himself getting drawn into the door. The world turned to a brilliant white before soon fading to darkness once more.

"Usagi! I need you to get up already or you'll be late for school!"

An unfamiliar voice broke Kenshiro's train of thought as he soon opened his eyes and started to take in his surroundings.

True to his suspicions, he was on a bed and seemingly inside of a girl's room. The sun shone brightly from the window from outside.

He got up and walked toward the window and saw, to his surprise, civilization. Cars were running, electricity worked, people walked around in a casual, nonchalant way. There was flowing water and there was grass and trees growing nice and strong. That, and not a single overgrown, roided, mo-hawked mook on a motorcycle in sight.

But that could not be. The world was reduced to a dust ball after nuclear annihilation. At least, that was what he thought.

"Usagi! Do not make me get in there and drag you out of bed! Get up now!"

Rabbit? Who is this Usagi?

As Kenshiro thought of this and what to say, he made his way across the room and then froze when he came across a large mirror.

There, before him, was a rather pretty girl, about fourteen, maybe fifteen years of age. She was thin but remarkably shapely for her age. Already she was about 5'3. She would grow up to be a tall, regal looking woman if this continued. Long blond hair fell behind her back, going down to the small of her back. Her eyes were a light blue that exuded an innocence that Kenshiro was not accustomed to seeing.

However, what bothered Kenshiro the most about this image was that it was the only on the mirror. And that bothered him. Alot.

Kenshiro decided to move his arm up and, to his surprise, the girl before him on the mirror matched his movements. He did this with the other arm and found that the girl mimicked him as well.

"Atta!" roared Kenshiro in a much girlie voice than he expected as he shot a fist out.

Sure enough, the girl in the mirror matched him, the angered expression on her face looking more cute than threatening.

It was then that Kenshiro knew.

He was in a different body.

Gone were the muscles, his beard, the seven bullet like scars on his chest carved in the figure of the Big Dipper.

"Usagi...are you okay? I heard you yell. Did you fall down or something?" asked a maternal voice from across the door.

"I'm fine." replied Kenshiro, again her voice sounding so very girly compared to her voice of old.

"Then I need you to get dressed already. Shingo has already left to school. I don't want you to be late!" replied the woman from across the door.

Kenshiro looked over to the closet and found there, hanging, a Japanese school uniform. She sighed. She could not believe that she was actually going to do this.

There is something amiss here.. I will blend in as much as possible as this "Usagi" girl until I can find out what is going on.

With that, Kenshiro soon got ready.

"Here's your lunch dear. Now hurry along before you're late to school." said Tsukino Ikuko, the blue haired matriarch of the family as she handed her daughter a bento box.

"Thanks." replied Kenshiro dully as she grabbed the box and proceeded to step out of the house.

"Is it just me or did she seem a bit down, Kenji?" asked Ikuko as she watched her daughter leave the house in such a calm, solemn matter.

"Don't worry dear, she's probably just feeling sleepy is all." replied the bespectacled man with the newspaper.

"I hope you're right dear."

As Kenshiro was making her way, she suddenly realized that she had no idea where this school was.

Knowing that it would do her no good to walk aimlessly around, she spotted a bunch of kids gathered together. Perhaps she could ask them where this school was so that she could go.

As she neared, she found that the kids were picking on a black cat.

"What are you all doing?" asked Kenshiro in a stern voice.

The kids froze at the sound of teenager confronting them.

"We were just...ummm-"

"I suggest you leave that creature alone." replied Kenshiro.

The kids soon ran away, leaving the newly teenage girl along with the cat.

Kenshiro looked over and was glad that the cat had not suffered any injuries from the kids harassing it. However, it did have a bandage placed over its head. Knowing the kids, they probably put it on just to yank it off and cause pain to the small creature.

The former martial artist growled. Even in this seemingly civilized time, people could still be cruel.

She stepped forward and cat seemed rather frightened by his presence. She soon spoke.

"I'm not going to hurt you." said Kenshiro in the most soothing voice she could muster.

The cat seemed to relax and soon, Kenshiro managed to pick the cat up and remove the band-aid from its head. She was a bit surprised of the crescent moon symbol on the cat's head.

Almost as if on cue, the cat soon scampered off Kenshiro's arms and ran off.

Kenshiro looked at the cat go off and wished it found its owner soon.

However, she still needed to get to school lest she be found out. That was the last thing she wanted right now at the moment, considering how she felt so helpless and weak in this body.

"Hey Usagi! What are you doing here? We're going to be late! C'mon!" cried a ginger haired girl as she ran forward and grabbed Kenshiro by the arm and proceeded to drag her along.

Kenshiro could not believe how weak she felt.

This normal girl was able to drag her new body along as if it were a rag doll. This was not going to be good, especially if she was confronted.

However, she buried her anxieties for now and proceeded to run along with the girl and soon managed to get to school.

"Naru Osaka! Usagi Tsukino! Both late again! I can't believe you two!" said Haruna Sakurada, the homeroom/math teacher for both Usagi and Naru.

"Aww, c'mon miss, no need to chew our brains out!" exclaimed Naru.

"It's going to be nothing compared to the chewing your parents are going to give you young lady with THIS on your exam." said Ms. Haruna as she presented Naru's test. It had a big, red forty five on it. Naru's face fell.

"And you Usagi! You need to stop watching tv and playing video games and get on the ball! I can't believe this. The second time in a row that you got the lowest grade!" cried Ms. Haruna once more as she shoved the test paper in Kenshiro's face, showing a big, red thirty on it.

While Naru looked like she was freaking out, Kenshiro kept her composure, despite her initial surprise. This Haruna woman was so strong willed. Women like that were scarce where he came from. Then again, she hoped that would not have to suffer going through a nuclear holocaust and then risked getting robbed and raped everytime she stepped foot outside.

"I apologize for my lack of diligence. It is a dishonor to myself, my parents and to you. I will do better next time." replied Kenshiro to the woman before her.

Ms. Haruna and half the class shut right up and stared at Usagi when she said this. Naru, especially, was wide-eyed and in shock. Since when did Usagi ever get serious and blame herself for her shortcomings?

"Ahem...right. Make sure you do that then young lady." said Ms. Haruna, though she was still a bit rattled.

Naru could not help but stare at her best friend. Did she hit her head or something? She didn't know but she was going to find out.

It was after school and Kenshiro wanted to make her way out of here as soon as possible. She needed to get to a secluded spot and meditate on this and her predicament.

"Hey Usagi, where you going?" asked the ginger headed girl.

"Naru?" asked Kenshiro in an unsure voice.

"Usagi, you were acting totally weird today. How 'bout we go shopping? I saw a new pair of boots that I know that you'll love!" said Naru with excitement in her voice.

"If I were you, Usagi, I would say no. Your grades are important and I'm glad you are being serious." said a bespectacled boy that joined them.

"Aww, Umino! Nobody cares about what you have to say. Go away!" cried Naru.

"But I'm serious. I didn't study and I only got a ninety. How am I going to explain this to my parents?" whined Umino.

"Tell someone who cares, will you weirdo." said Naru in a condescending voice.

"If it is all the same to you lot, I'm going off on my own." said Kenshiro as she got up and attempted to leave. Before she could go very far, however, a feminine hand grabbed her arm and stopped her.

"Oh no you don't! I see that pouty look on your face. You're coming with me. Maybe we can look at some jewelry over at my mom's store. I know that'll cheer you up!" said Naru with a wide smile.

"Don't go Usagi. It'll only rot your brain." said Umino with a warning.

"Shut it, Umino!" cried Naru.

Kenshiro could not help it. She did not want to attract more suspension. Better to go with this Naru girl and entertain her.

"I'll go." said Kenshiro in an unenthusiastic voice.

"Yay! C'mon let's go already. My mom's having a huge sale today!" cried Naru.

Dark Kingdom: North Pole

Queen Beryl sat upon her throne of stone as she watched upon the crystal orb on her staff. Everything was going along much faster than anticipated. Already, she could feel it in her heart.

After being dormant for nearly ten thousand years, she and her kingdom were soon revived from suspended animation by the great Metallia, who had finally attained enough power for the feat.

This weakened Metallia greatly, but that was alright. Queen Beryl was there to set things in order. Already, they had only been revived for a week and much progress had been made. Queen Beryl's goal was to revive Metallia to her former power and glory.

To do so required a tremendous amount of energy. Even sending agents onto the face of the Earth unhindered would have taken over fifty years to acquire the energy she needed.

Metallia, however, anticipated this when she fell over ten thousand years ago. She managed to capture key energy sources before her fall and then lay dormant for thousands of years, waiting until the time was ripe.

It was by the power of these "energy sources" that allowed Metallia to revive the Dark Kingdom without sacrificing too much of her own power.

Queen Beryl was the only one who was made aware of this and the evil queen smiled. She knew that there would be no resistance. She could gather energy without arousing suspicion, then, when the time was right, Metallia would soon have the power to destroy humanity and pave the way over to a new order.

"Jedite!"

A blue flame flickered in the hall of the Dark Kingdom. Various youma were in the background, ready to serve their queen at a moment's notice.

"The time is ripe. We are to gather but a bit more energy and the world will be ours. Speak of your progress on Earth." commanded Queen Beryl.

The flame soon dissipated to show a handsome, blonde haired man with piercing green eyes.

"Everything is going according to plan. Morga is on Earth right now with a scheme to gather necessary energies. At the rate we are going, it should only take us a year, at most, to gather the resources we need." said Jedite.

"Good. Let us hope, for your sake, that everything goes smoothly." said Queen Beryl.

"Of course, my lady."

It was not long before Naru managed to drag her friend over to the jewelry store that her mom owned.

The place was packed with women who were dying to get their hands on some jewelry.

"My gosh, I've never seen this place this packed before. I wonder what's got into momma?" asked Naru, more to herself than anything.

Already, Kenshiro wanted to leave. She had no reason to be here. She needed to find out exactly what was going on with her and why she was inhabiting the body of a fourteen year old.

"Oh Naru, what a surprise! You brought your friend, Usagi, as well I see. Well come and look all you want. We're having a super sale today, ninety percent off all diamonds!" said Mayumi Osaka.

"I guess we can take a look around. I know you always liked brim stones, Usagi." said Naru with a smile on her face.

Kenshiro felt very uncomfortable being in close proximity to shop owner. She seemed to exude a wicked intent that was so familiar to her when she cut down many of Shin's henchmen.

"I'm sorry, but I have got to go." said Kenshiro as she turned around and started to make her way out of the store.

"Wait, Usagi!" said Naru as she ran after her friend.

"You're leaving already? We didn't even have time to window shop!" cried Naru.

"Now's not the time. I have got to study." fibbed Kenshiro in a stern voice as she soon took off in the direction of Usgai's house.

"Oh Usagi. You should know better than to keep secrets from me." said Naru in concern.

Kenshiro finally made her way back to the girl's house. While she did think of going over to the park to perhaps meditate upon the events thrust to her, she figured that it would not be the safest course of action. She still had no idea what this body's limits were and she was not going to find out, at least, not yet.

As she walked in, she soon bumped into the girl's mother, Ikuko Tsukino.

"Usagi honey! How did you do on your test? I know you and Umino stayed up so late over the weekend to study." said the blue haired woman with a smile on her face.

Kenshiro was never a great liar and she was not going to start now.

"I'm sorry. I failed the test utterly." said Kenshiro as she handed the paper over to the woman before him. Her smile faded as she soon went into a fit of rage.

"Didn't you study that entire time or were you just pulling my leg? Seriously Usagi, I can't believe this!" roared Ikuko.

"I intend to make amends and no longer dishonor you with such a poor showing. I will do better on the retest and reclaim my honor." said Kenshiro sternly as she then walked past the woman and made her way upstairs to "her" room.

"Usagi..." mouthed Ikuko to herself softly, very much stunned at her daughter's seriousness.

It had been nearly an hour since Kenshiro had sat down upon the girl's bed and meditated. During the course of her meditation, she began to have an idea of the girl's power and what she could do with this body, should push come to shove.

However, she was no closer to finding out the riddle of her existence in this body than she was this morning. The sound of that woman's voice, so full of burden and despair, came back to her. Perhaps that dream had something to do with his current predicament but she could not be sure.

The window suddenly snapped shut and Kenshiro rose fully, getting into a defensive position.

"Show yourself! I know you are in here." said Kenshiro in a threatening voice that sounded way too cute for her own liking.

"My, you are quite the alert one aren't you." said a feminine voice.

Kenshiro attempted to locate the source of the voice until her eyes strayed to that of the black cat on her bed. The cat was the same one she saved earlier in the day.

"Only a cat. I must be getting paranoid." said Kenshiro as she made her way to pick the cat up and take it outside.

"On the contrary, you are not getting paranoid. I am here because you are the chosen one!" said the cat.

Kenshiro stopped short and stared at the cat with a look of suspicion. Was this some sort of sorcery or was she going mad?

"You can speak?" asked Kenshiro.

"I don't think your ears would lie to you, now would they." said the cat.

"I see. Well, whatever business you have with me must be done another time. I must resume my meditation." said Kenshiro as she proceeded to sit back down on the bed.

"No! You must listen to me. You are the chosen one, Sailor Moon! You are here because the Dark Kingdom is now at work. Your friend, Naru, is in danger!" said the cat.

At once, Kenshiro stood back up. While she did not know Naru that well, the girl did show her kindness and she did not want any misfortune to fall upon her.

"I see. I will head over to the jewelry store." said Kenshiro.

"Wait! I need you to put this brooch on first!" said the cat as she produced a golden brooch.

"What do I need this trinket for?" asked Kenshiro as she raised an eyebrow.

"Just put it on and say 'Moon Prism Power', okay?" said Luna.

Kenshiro had no time to waste and immediately jumped out the window.

"Usagi wait! You need to put the brooch on!" said Luna as she grabbed the brooch in her mouth and ran off, following Kenshiro.

Inside the jewelry store, Naru was getting strangled to death by some sort of monster that posed as being her mother.

"Somebody, help me!" cried Naru as loud as she could.

"Save your breath! Nobody will come and help you. Queen Beryl will gather the energy from you feeble humans and will soon exterminate you like the rats you are!" cried the youma as she squeezed Naru's neck even harder, and dropped her disguise as a human.

"I suggest you let her go lest you die." said a voice.

The youma, Morga, looked around at the source of the voice.

"Who's there! You better show yourself!" threatened Morga.

Out of the shadows came Kenshiro, who was cracking her knuckles. Next to her was a black cat with some sort of brooch in its mouth.

"I know you! You are this human's friend! Leave now, little girl, and I'll spare your life." said Morga with a threatening voice.

"Usagi...run..." mouthed Naru silently before blacking out.

Kenshiro looked around her and noticed the fallen bodies of the women in the store earlier. She could tell they were not dead but they were in critical condition. She would need to kill this monster here and now.

"Why would I leave from scum like you?" said Kenshiro once more as she took a step.

"Usagi! Take the brooch now! That's not an ordinary human! That's a youma!" cried Luna.

"Monster, man or devil, it makes no difference to me. The art of Hokuto Shinken knows no defeat." said Kenshiro as she took her fighting stance.

"Arrogant little whelp aren't you? Then take this, the power of the Dark Kingdom!" roared Morga as she threw Naru aside and raised her arms.

At once, all the women rose from the ground and proceeded to attack Kenshiro.

Kenshiro knew that they were possessed and it would not do to strike their pressure points, lest she accidentally kill them. So she ran forward and, as quick as lightning, hit them all with a series of non-lethal attacks. Even in this fourteen year old girl's body, it was enough to knock out the twenty or so women after her.

"Hmm, not bad for a human, but can you take fighting against the Dark Kingdom's elite solider?" asked Morga as she stretched an arm out Kenshiro, no doubt to impale her.

"Usagi, get out of there!" cried Luna.

Kenshiro did not listen as she grabbed the wrist of the youma effortlessly and proceeded to dig her fingers into the skin of the youma, causing it to cry out in pain.

"Let go! That hurts!" cried Morga as she threw another hand out and produced a black lightning, shooting at Kenshiro.

Kenshiro did not know whether this body could take that attack and promptly let go and dodged out of the way.

Morga, with inhuman speed, managed to get behind Kenshiro and wrapped her arms around the teenage girl body.

Kenshiro gritted her teeth in pain and annoyance.

"It's over now! I'll crush your bones down into dust!" roared Morga.

"Usagi!" cried Luna in concern.

Kenshiro tried to get out of the creature's grip, but it was too strong. Perhaps had she been in her old body would she have been able to do so.

She had no choice but to do this. She did not know whether the girl's body could handle the stress but it was better than dying an early death.

"Ahhhh!" roared Kenshiro.

Immediately, a white aura began to engulf her body and tear the top portion of the school uniform she had on as she drew out 100 percent of this teenage girl's total potential.

The results were surprising.

Even with this girl's body, unlocking its hidden power was more than enough to power her way out of the youma's grip. She turned around and saw the frightened look on the youma's face.

"W-What are you?" asked Morga in surprise and shock.

Kenshiro did not answer as she just ran forward and jammed both thumbs on the youma's temples.

Hokuto Shinken: Zankai-Ken (The North Star Fist of Remaining Regrets!)

"I have struck vital pressure points. You have seven seconds left to live. I suggest you use that time to reflect upon your sins." said Kenshiro as she stepped away.

"Haha...is that it? I hardly felt anything at all!" roared the youma.

Kenshiro stopped though she still showed her back to the youma.

"Really? Then why is it that you are already dead?" asked Kenshiro once more as she just stood there.

"What do you mean de-"

Before the youma could say anything else, she felt pure and unimaginable pain in her head and in the core of her body. She felt like a burning sword had run through her body as it was twisting and contorted.

"No! I will not die!" she roared before her head exploded in a mass of purple blood, her body splitting in half.

Kenshiro just sighed as she started to walk away.

Luna, on the other hand, was absolutely gobsmacked. How in the world did Usagi have the power to fell a youma with just her bare hands?

"Usagi! Wait! How did you do that?" asked Luna in clear surprise.

Kenshiro looked over at the cat with a blank expression before answering.

"What I did just now was part of my martial art, Hokuto Shinken, or Fist of the North Star." replied Kenshiro.

Luna thought of this for a moment before suddenly coming up to a conclusion.

"You're really not Usagi...are you?" asked Luna.

"I am sure you could have deduced that from what I just did right now." replied Kenshiro calmly.

"Well, it seems we both have many secrets to tell." said Luna in almost a whisper.

"While it is not in my nature to ask for assistance, I am truly lost. Perhaps you can help me. However, whatever it is that I have to tell you is for your ears only. I hope you can understand that." said Kenshiro.

"O-Of course! Whatever you say!" said Luna hurriedly.

"Then let us be off." said Kenshiro as she was walking outside the jewelery store.

"Wait!"

"What is it?" asked Kenshiro.

"You need to put a shirt on. You destroyed Usagi's school uniform during your battle!" said Luna.

Indeed, Kenshiro looked down to find a pair of soft globes as opposed to her pecs of iron. Perhaps going full power would not be so prudent while she was still in this body.

"I see." said Kenshiro dully as she then went through the annoying task of finding a shirt to put on.

Author's Note: I will be referring Kenshiro as a "her" now. Hope you all enjoyed.
