Enter the Headmaster

The clouds overhead shifted by obscuring the fool moon as a smirking Hiei stood atop one of the buildings at the docks on the outskirts of the city. His black cloak billowed behind him while the Jagan eye opened wide, taking in everything around him under the moonlight.

'Their mistakes were simple ones. Gouki was too overconfident and Kurama had too much sympathy for his human prey.' thought Hiei. He then unsheathed the shadow sword and stared at his reflection on the blade.

'I guarantee I won't make the same mistakes. My plan is too good for that. It's better this way. The others lacked the courage to use the weapons as they were intended. I will, but first I'll eliminate those idiot spirit detectives. Naruto Uzumaki and Yusuke Urameshi your time has come!'

He leaped from his position slashing the glowing blade before vanishing into the night.

X-X-X-X-X-X

The bell rung as a typical school day at Sarayashiki Junior High School progressed. Per normal procedure, Yusuke was skipping class on the roof to have a meeting with Botan and Naruto. Naruto worked on his chakra control standing parallel to the ground while balancing a couple of leaves in his hands on the side of the entrance to the stairs. Botan sat on top of the same structure with her legs dangling over the side.

"You know what's funny, I get to do the kick ass spirit detective thing in between training all day while your still in school!" mocked Naruto.

"I'm the toughest kid here at Sarayashiki Junior High School. I run this place! Your just a drop out." retorted Yusuke.

"Yeah Right! I'm proud graduate of the Konoha Shinobi Academy! I finished school years ago and was #1 in my class." bragged Naruto.

"You were the dead last of your class." corrected Botan.

"Technically, I killed that guy who graduated #1, that means I get his spot. You're lucky to be working with a legend like me, perhaps I'll eventually let you in on my secret training." boasted Naruto.

"It's not like your stupid training has accomplished anything useful anyway. You still can't use your special attack yet, while the spirit gun is loaded and ready for action." declared Yusuke in a cocky manner.

"You only have one bullet!" yelled Naruto.

"Yeah, yeah." Yusuke waved him off dismissively.

"Now, now boys. If it weren't for the healing powers of your lovely spirit detective manager, you'd still be limping around from that first fight." reminded Botan.

"Yeah, well do all the assistants wear school uniforms too? Or do you just like the navy girl look?" mocked Yusuke.

"I definitely like it!" declared Naruto as he'd taken to resting at the bottom of the wall he'd been standing on and trying to look up Botan's skirt. She jumped down from her position and stomped on his stomach.

"How cruel..." Naruto gasped.

"I'm not wearing this for kicks. Some people actually try to blend in with the environment when following you around school." she replied giving a pointed glare at Naruto.

He shrugged it off, "Don't disrespect the orange. Anyway I'd be caught dead before you find me in a school uniform, or attending school for that matter."

"I almost forgot! Koenma decided to release Kurama on good behavior after the punishment board reviewed his case." informed Botan.

"That's good to hear." replied Yusuke.

"Yeah now all we have to do his beat the midget and get back the sword, then the case is closed." added Naruto.

"And we've got three days to do it." said Yusuke.

"That will be easier said then done. Hiei is the toughest opponent you'll face by far. He's both cunning and ruthless and he'll do anything to get what he wants." warned Botan.

"Well, they don't call me the number one unpredictable ninja for nothing. We'll crush him, I guarantee it." proclaimed Naruto.

The door to the roof suddenly opened and Keiko walked out turning to Yusuke.

"There you are Yusuke. Mr. Takenaka's looking for you. You're the only person who hasn't turned in a book report." said Keiko.

Yusuke waved off her concern, "I've been too busy to worry about that stupid class."

"Hard to balance school and work huh?" said Botan.

"I don't think he would have done it if we weren't hunting demons anyway." stated Naruto.

Yusuke was now annoyed, "Do you guys mind?"

"No not really!" giggled Botan as she walked up to Keiko. "Ms. Keiko it's so nice to meet you now that I have my own body. I just want to say how great a person you are. When you ran into those flames to save Yusuke, I nearly melted in my shoes!"

"Do I know you?" questioned a completely confused Keiko.

"You must be saint to put up with this lug. Battling de..." began Naruto only to be cut off.

"Hey!" yelled Yusuke bashing both of them in the back of the head.

"Keiko doesn't know anything about Spirit World so just keep it quiet alright!" he warned them quietly.

"Well sooner or later you going to have to tell her all about it, or things will get complicated..." advised Botan.

"Time for lunch!" replied Naruto as he walked off.

"See you later!" Botan gave a wave before following right behind him, leaving Yusuke and Keiko alone.

"Tell me what soon?" Keiko asked Yusuke.

"Damn! She just had to bring you in on this too.." grumbled Yusuke.

"Bring me in on what?" asked Keiko again.

He waved her off dismissively, "It's a long story, I'll tell you later."

Keiko became slightly annoyed, "Oh. Well, I just came to tell you about the book report so you wouldn't get in trouble."

"Wait! Hold on Keiko, I want to talk to you." said Yusuke as she turned to leave.

"You do?" she turned back to him with a faint blush.

"I was wondering if you could to do my homework?" he asked.

"Oh? Is that all I'm good for now?" she retorted angrily.

"Well me, Botan and Naruto are going to be busy today." he answered.

She only heard the first name before stomping away completely ticked off, "Is that fact!"

"Hey! It's not what your thinking!" pleaded Yusuke as he chased after her.

X-X-X-X-X-X

A few hours later Yusuke found himself in detention listening to Takenaka drone on and on when his demon detector suddenly went off.

"Dammit! He's here, looks like about one mile away." exclaimed Yusuke as jumped up an ran out the door. "Sorry old man! I heard my mom calling!"

"Wait Yusuke, we're not done yet! And next time use a better excuse!" yelled Takenaka.

As soon as he exited school grounds he ran into Botan and Naruto.

"So your detector sensed him as well?" Botan asked.

"Yeah, but it's weird. His location is well beyond the limits of this thing yet I still picked it up." answered Yusuke.

"He's got enough power to set the thing off from anywhere in the city," supplied Naruto. "He's trying to lead you to his base, but I already know where it is. I've had shadow clones searching the city for odd activity. There has been some strange movements at one of the warehouses at the docks."

"That's not the only problem! Hiei has been using telepathy to warn you he has Keiko and will only release her in exchange for the two artifacts!" informed Botan.

"What are we waiting for let's go!" roared Yusuke.

X-X-X-X-X-X

Once they arrived at the docks, Naruto pointed out the building his clones identified as suspicious, "His hideout is over there."

Yusuke marched over and opened the large door. "Where are you bastard! Come on out, so I can kick your ass!" called out Yusuke.

The door suddenly closed behind them and they came face to face with a hoard of people hovering around like zombies.

"What the hell happened to them?" questioned Naruto.

"Hiei must be controlling their minds. There was no information about this in the records department, to control so many people at once he must possess the Jagan." suggested Botan.

"Jagan?" questioned both Yusuke and Naruto.

"Well done!" stated Hiei as he laughed evilly. He emerged from the crowd of people Jagan flaring and wielding the shadow sword. "I used my power to round them up this morning. They won't do much good against you two, but they make for excellent scenery."

"Big deal! You're a midget and a triclops. It's still two on one." taunted Naruto.

Hiei snorted at the insult, "Fools, the whole lot of you. Normal humans would have succumbed to the effects of my eye by now. Looks like Koenma got lucky with his picks, but you are both still a couple of A-class morons. That's why I brought some insurance."

Two guys holding up Keiko emerged from the shadows.

"Keiko! Let her go! She's got nothing to do with this!" demanded Yusuke.

"I'll hand her over if you've brought the weapons." countered Hiei. Yusuke pulled out the orb and the mirror and handed them over.

"Such a good boy, the orb of baas and the forlorn hope, you can have her." Hiei commanded the two men holding her to let her go.

"That was a mistake." stated Naruto calmly.

"Did you really think we we're going to hand over the artifacts that easily. Now that you've handed us Keiko we're going to rip you to pieces." roared Yusuke.

The two objects in his hands, suddenly vanished in puffs of smoke to reveal a pair of Naruto clones. The duo attacked when Hiei suddenly vanished and reappeared a on top of a crate to the left of them.

"He vanished..." exclaimed an astounded Yusuke.

"No that was pure speed..." whispered Naruto.

"Looks like one of you is smarter than I thought, but did you really think that was the full extent of my plan? Take a closer look at the girls forehead." said a smug Hiei.

"What the..." muttered Yusuke as he leaned down and found the wound on Keiko's forehead.

"This wound is similar to Hiei's eye...no! It's not a wound, it really is an eye!" exclaimed Botan.

"Got it in one! I've returned her body, but her life is still in my hands! Hahaha!" cackled Hiei.

"Dammit! The eye is opening!" yelled Yusuke.

"That's the beauty of it! Once the eye opens she'll become my first subordinate in my new demon army!" proclaimed Hiei.

"Get out of the way!" yelled Botan as she brushed Yusuke aside and starting using her healing powers on Keiko.

"Interesting. Your companion seems to be able to neutralize demonization. Such high classed spirit healing, a very capable companion you have indeed. But can she keep it up? Without the aid of medical herbs the strain on the healer is very great, she could end up losing her life as well!" taunted Hiei.

"He's right, I can't release too much spirit power for long!" warned Botan.

"Yes, let's play a game now! I've got the antidote hidden in between the blade and hilt of this sword! She won't survive unless she takes it, but then again you won't be fast enough to take this sword from me with a hundred years of training..." a kick to the gut delivered by Naruto silenced Hiei's rant.

"No Games!" declared Naruto in a tone that meant all business. The kick sent Hiei in the direction of Yusuke who followed with a punch to the face and an elbow to the ribs. Hiei staggered back away from him stunned.

'The blond one somehow switched positions with that crate next to me in an instant, and the other's power increased ten fold...' thought Hiei.

"I see. You two are the worst kind of human trash. When someone threatens your friends, you become even harder to kill." growled Hiei.

"You are beyond redemption. I'll feed your remains to the stray dogs of the city." declared Yusuke with an ice cold tone. Hiei ignored his threat.

"Not snatching the sword back when you had the moment of surprise will be your fatal error. I won't be so careless..." Hiei stopped to dodge a punch from a Naruto clone.

"Less talking, more fighting!" yelled the other two Naruto's that charged him. Hiei suddenly vanished again.

"Fools! Do you think you can follow my speed!" echoed Hiei's voice as he blurred around the room. Right as he flashed in front of Yusuke, the green clad spirit detective nailed him in the face with a punch again.

"As that all you can do midget? Just jump around a little?" taunted Yusuke.

"I normally don't beat up the physically handicapped, but I'll make an exception in your case." stated Naruto as he and clones marched towards Hiei's downed form, cracking their knuckles.

"Shit!" shouted Hiei as he rolled over and jumped back, gaining some separation. He discarded his cloak as he stared them down. "To think I've been forced to revert by mere humans...You will learn true fear!" Hiei roared as he suddenly transformed with eyes sprouting all over his body and his skin turning green. His Jagan flared and energy shout out of it wrapping around Yusuke and paralyzing him.

"Don't forget about us!" yelled Naruto as he and his clones charged Hiei, but the transformed Demon's speed proved to be to much for him. The clones were quickly dispatched by a couple of slashes of the shadow sword. Hiei then deflected the original Naruto's punch before stabbing him in the chest with his claws. As he pulled his hand from Naruto's chest massive amounts of blood gushed out.

"You managed to move slightly at the last second to avoid an instantly fatal blow, but you'll bleed out soon enough." As Naruto collapsed to the ground he turned his attention back to Yusuke.

"No one to help you now!" bellowed Hiei as he started hammering down punches on the immobilized detective.

'Dammit, I've got to break free!' thought Yusuke as he struggled to try and move.

"Do you understand the difference in our power now?" questioned Hiei as he paused in his assault. "For a human your power is impressive. In honor of that fact, I'll grant you a swift death."

Hiei raised the shadow sword and charged Yusuke with a battle cry, "Die!"

'This is it...' thought Yusuke as he awaited the blow. However, as Hiei went to stab Yusuke, Naruto appeared in front of him stopping the blade with his bare hands.

"What! You should be dead!" yelled Hiei.

"It's take a lot more than that little scratch to kill me!" retorted Naruto. 'Even without the fox, my regeneration is still top notch.'

As the blade started to cut into his palms Hiei started to laugh.

"Fool! Now you've been sliced by the sword! You'll soon be under my command!" cackled Hiei.

Naruto's response was to lick up some blood that leaked out of the corner of his mouth and spit at Hiei nailing him in the Jagan eye on his forehead. The short demon staggered back, blinded. The restraints around Yusuke were immediately released.

"How fortunate. Hiei's other eyes are merely for show. The true power is the original Jagan on his forehead." Kurama's voice called out from behind them.

The duo shouted as they turned to face the redhead, "Kurama!"

"I came to repay the favor from helping with my mother. I feel you both would kill me for interfering with your battle, so leave the girl to me. Concentrate on Hiei." Kurama then ran over to aid Botan.

"It's pretty hard to hit target moving at those speeds. Since it's your girlfriend he jacked up, it's only fair you land the finisher. I'll lock him down." suggested Naruto.

"How nice of you. I guess I'm obligated to let you have the next one." replied a grinning Yusuke.

"Of course." responded Naruto with a smirk.

"Throwing your lot with these fools...I kill you for this Kurama!" bellowed Hiei.

"You have to worry about getting through us first." proclaimed Yusuke.

"You two! Your power! You keep getting stronger every time you escape!" he yelled at Yusuke before pointing to Naruto. "And I know I cut you with that damn sword! How are you still standing! No more I'll kill you both with my full power."

He charged aiming to decapitate Yusuke with the Shadow Sword but Naruto intercepted, blocking with a kunai. Hiei countered with a roundhouse kick that sent Naruto flying across the room and into the opposite wall. Yusuke used the opening created to punch Hiei sending the short demon back towards the middle of the room where he landed on his feet and moved to start another charge.

"Yo ugly!" shouted Naruto as he threw a kunai at Hiei's back. Hiei heard the shout from behind him and saw the weapon moving at him as if it was in slow motion. He arrogantly waited until the last second before moving slightly to the left to dodge, however the kunai vanished in a puff of smoke revealing Naruto. Hiei reacted by slashing across the old wound on Naruto's chest with the shadow sword, but Naruto fought through the pain and the blow to lock onto Hiei with a death grip holding him in place.

"Now!" yelled the blond.

"Spirit Gun!" yelled Yusuke firing off his attack.

"Fool! You'll take damage as well!" roared Hiei as he struggled to free himself.

"So be it!" declared Naruto as the blast hit Hiei in the chest, forcing him to drop the sword and carrying the duo across the room slamming them up against the wall.

"You idiots..." murmured Hiei as he collapsed into unconsciousness. The Naruto behind him vanished in a puff of smoke as the real one emerged from behind a crate.

"Take that bastard!" proclaimed Yusuke as he kicked the downed Hiei in the side.

"Let's go see how she's doing." said Naruto as he walked towards Botan, Kurama, and Keiko. Kurama had picked up the sword right after Hiei dropped and helped Botan apply the antidote to Keiko.

"Don't worry guys, the antidote is working. She'll be back to normal in no time!" happily informed Botan.

"Thanks for the help Kurama." stated Yusuke.

The redhead waved off the gratitude, "It is was nothing."

"I must say that was some excellent teamwork you boys showed out there." praised Botan.

"Yes, you even had me fooled. How did you get your clone to survive the slash with the blade?" Kurama asked Naruto.

"It didn't, that was the real me." They all looked closely to see the slowly healing slash wound on his chest as he removed his tattered jacket. "I switched right before his attack hit."

"You should have said something! Botan give him some of the antidote!" yelled Yusuke.

"I don't know if there's enough left!" shrieked a panicking Botan.

"This doesn't make sense, he should have started transforming by now like the girl." stated Kurama.

"Hey, if having the Kyuubi in me for all those years didn't turn me into a demon I doubt that this will. Besides he cut me with it before and nothing happened..." Naruto suddenly went down to his knees before collapsing to the ground as he passed out.

X-X-X-X-X-X-X

As Naruto's eyes fluttered open, he found himself staring up at the familiar white sealing of a hospital room.

"What the hell happened?" he yawned while sitting up.

"Let's just say you had an interesting reaction to the shadow sword." He turned to see Botan sitting next to his bead reading.

"Huh?" he asked eloquently.

She waved off his confusion, "Someone qualified will be along shortly to explain exactly what happened."

"Okay, then where am I?" he asked.

"The Spirit World Medical Center, can't expect to get treated for being cut with a demonic sword in the human world. You've been out for a couple of days." she answered when Naruto's stomach suddenly growled. Immediately the door opened to reveal Kushina carrying some ramen, "Looks like I'm right on time!"

"Yeah Mom you rock! Ramen!" exclaimed Naruto as he started to chow down.

"So how did he take the changes?" Kushina asked Botan.

"He hasn't noticed yet." replied Botan as she turned a page.

"What changes..." Naruto started to question after he slurped up a mouthful of noddles when he looked at his hands. He was wearing some black fingerless gloves with orange spirals on the top that seemed to be clamped on to his wrists so he couldn't remove them. Botan then handed him a mirror, and as he looked at his reflection he noticed his whisker marks were more defined and his eye looked like a slitted version of the Jagan.

"Wow! What the hell happened!" he yelled.

"Don't worry all will be explained in due time." Koenma responded as he entered with a strange hooded man who possessed glowing eyes following close behind. "Naruto, this the man who you'll be working for when I don't have higher priority cases for you and Yusuke to work on together."

The man introduce himself, "My name is Tenmei Mikogami, but you can just call me Headmaster."

"Headmaster of what?" questioned Naruto.

"Your new school of course, the Youkai Academy!" informed his mother.

He stared her down with a look of betrayal, "Curse you! The ramen was a peace offering. No matter, I refuse!"

"You don't have a choice. Youkai academy is the place you'll be policing as a spirit detective. Long ago the demons were allowed to freely roam in the human world, once the point came where it was decided barriers were needed because of the constant conflict, some tribes of demons were allowed to remain in the human world provided they coexisted and blended in peacefully. The yokai or monsters of today's world are descendants of these demons. The school is where they go to learn how to blend in with human society." explained Koenma.

Naruto still wasn't persuaded, "Send Yusuke there! I'll cover his territory."

"He's not old enough to be admitted as a student undercover." countered the Headmaster.

Koenma decided to try a different tactic, "There is some good news. You've regained a significant portion of your strength and abilities."

"You're right, I feel about as good as I did right before the training trip before well you know..." he trailed off.

'Yes right now your comparable to a low B-Class demon, or low A-class monster on the academy scales. You still possess the potential to ascend far beyond your current limitations.' thought the headmaster.

"The reason your power was out of whack before was because remains of the Kyuubi's demon chakra still remained in your system without the seal to regulate it. The chakra wasn't causing too much trouble for you because it remained dormant. After being sliced by sword twice the demon chakra awakened and multiplied to point where it flooded your system and causing your body to start transform. The gloves I placed on you stabilized your body and prevented the transformation. When you finally reach a point where you can tap into your full power, without destroying your body. The gloves will come off." explained the Headmaster.

"Oh, Haha." deadpanned Naruto. "So, I've become a demon now?"

"Maybe." answered Koenma.

Naruto stared at him dumbfounded once again, "Huh?"

"We don't know what you are since your powers are still evolving. I have stabilized your powers for now, but you could maintain your human nature, become a full demon, or become some sort of hybrid. We don't know." replied the headmaster.

"Eh, does it really matter? I mean I'm still me right?" questioned Naruto. At this he was glomped by his mother.

"Yes that's exactly right! You will always be my handsome little boy!" she cried as she hugged him to death.

"I believe that's enough for today. Get some rest you report to the academy in a few days!" stated Koenma before he and the headmaster exited quickly.

"Hey! Wait minute! Get back here! I never agreed to that!" yelled out Naruto to no avail as he was unable to escape his mother's grasp. Botan continued reading, giggling at his predicament.

X-X-X-X-X-X

"So, could you get a reading on what he is?" questioned Koenma once the were outside..

"No, based on the unique state of his origins, he is still evolving. As he grows his demonic nature will eventually solidify, however his partial absorption of the Jagan is quite intriguing. He along with your other detective is very interesting."

"So basically a bigger pain in the ass than I ever could have imagined. All that potential I saw, I was too smart for my own good..." groaned Koenma.

A/N: The next few chapters will shift into Rosairio+Vampire for a little while, establishing it's roots there. The girls from there hooking up with Naruto will be Moka (both of them) and Mizore.
