Chapter 1- The Mission.

Starts Now

Today was a peaceful day in Reikai for our hero. Well as peaceful as it gets anyway. Nasariu Kata Once a human with a heavy burden that became one of his greatest strengths. He was now a full fledged demon but not just any demon King of the Demons by rights of succession by his burden.

Ten thousand years earlier the Demon king Nasariu a five headed dragon with ten tails and one of the fifteen immortals set in place by Kami. All the immortals were invulnerable no one but Kami himself could kill these beings. They were to be the protectors of the universe each given their own domain. But since immortality could get very lonely Kami granted them a power to give a spouse they would take one day a offset branch of immortality so they would stay with them through eternity. But though it was immortality it was an artificial form which meant they were not invulnerable so they could be killed.

Nasariu's wife that he had taken a dragon like himself grew heavy with eggs and left to lay them in her own dimension. Bad news hit Nasariu and rampaged through a dimension known as Earth or Ningenkai destroying everything in his path. Why you ask because his wife had been slain in her sleep by some ningen's. For nothing more than to make them look good. The ningen's. They tried to kill the enraged hydra but he could not be killed as he was a being like king Enma an immortal being to keep the peace.

King Enma ordered his task force comprised of hand picked ningen's with the power of spirit energy and sent them off to stop Nasariu. As the fight proofed futile one spirit detective as they were called used his very life force as a sacrifice so that lord Enma also known as the Shinigami (not sure if this is spelled right) could rip Nasariu's immortal soul and fuse it to a new born child.

But his soul could never be destroyed or passed on because Kami saw his punishment fit for him he improved the seal so that Nasariu's soul was sent to a new vessel every four generations. But the cycle stopped at our hero as he became the new Demon King.

Nasariu Kata a normal ningen lost both his parents before he was even born. His parents were in a car crash neither of them survived. But Nasariu was c sectioned from his mothers body and was labeled an orphan. He grew up in an orphanage alone with no parental guidance at all. When he went to school he was picked on at school and beaten by his teachers for being different. He had orange hair and red eyes as that was not normal for humans and he had no name. When he was ten he decided to fight back against his teachers but ultimately ended up a bloody hump of flesh.

That's when he met Nasariu. Nasariu promised him help and protection from the people who wronged him. That's when he started training in how to use reiki then he was planted with the jagan eye. Three years later he was scouted by Koenma Lord Enma's son. Over the years he grew in power and then the worst possible thing happened.

A new dimension opened to a world of demons. It was nothing like demon world at all. They were power hungry, jealous, and proclaimed themselves the beings with the right to rule all worlds. The ex king of the Nether World Yakumo saw this and joined them ultimately becoming they're leader.

There was a large war which almost ended in the destruction of Reikai and all other dimensions. But Nasariu Kata who had taken up the name of his demonic father figure was at the brink of death when Nasariu did not want the boy he saw as a son die gave him his power. He was transformed into a dragon. He gained all ten tails and the title of Demon King but got something extra. He was granted his demonic fathers immortality.

The tides changed from that point on as Nasariu kept growing in power by gathering a few relic items from a dimension known as the Necroverse which Kami had created as a prison for any who entered would be permanently moralized down to the soul. Nasariu took the risk and succeeded but not without a price. His being contracted a new type of degeneration disease sure him being the only one but he could not sustain a body for more than two hundred years. But the good side effect was he gained a new power from within his body witch took form of two swords.

Using his new power and the found relics he ad King Enma sealed the new demon universe shut to never open again. But even so they felt uneasy about the seal. So from then on Nasariu Kata was granted the position of Watcher of the Dimension.

Nasariu had nothing to do now that he had a new position. He was not allowed to go on active duty so he turned to gaining knowledge but never allowed his power to diminish. He also learned he could revert to a ningen form with blood and all. But his orange hair was now black. When he became twenty he had logs on all universe, gained unrivaled knowledge, and created new technologies for to help other people. But today he was summoned by Enma for a surprise meeting.

These new demons had given demon's bad names and were saw as the enemy of Reikai and he was dreadfully worried that he would now be exiled for being one even after all his deeds to Spirit World and all of his loyalty would now be thrown out the window and he would now be sent to a barren universe and never allowed to leave.

Nasariu stood in front of Enma bowing. "Nasariu-san there is no need to bow to me we are both equal beings in my court you are to be referred to as Reikai's greatest ally." Enma told him letting him stand before him as a lord not as a demon. "I have called you here today to offer you my place as Shinigami and the new ruler of Reikai as my son refuses the title if you choose to accept you will be tested to see if you are worthy." Enma said shocking Nasariu as he was a human who became not just a demon god if you will. But he was king of all demons.

"Enma-sama I humbly accept your offer I will do anything you as of me!" Nasariu said bowing.

"Normally I would hand over my thrown to you right here and now but my council demands that you prove yourself worthy of the title but they do not see you already have." Nasariu beamed with pride. "But they are idiots down there, but there have been anomalies in the cosmic design due to the event of me being summoned to a universe that came to existence five years ago I had to seal your fathers general Kyuubi into a child." Nasariu's face paled a bit at this as his fathers generals had mysteriously disappeared six years ago.

"Enma-sama that is disturbing news but what does this have to do with my mission?" he asked not trying to be irrespective.

"Perceptive as always Nasariu-san and this is the test you will go there with three quarters of your power taken from you and your age will be altered so that you are five years old and you may choose two allies to take with you and you will have twenty years to fix the problems the universe now faces as a organization of ningen's are after your fathers nine generals and if they succeed they could rip the seal from the demon universe stop them and protect the universe!" Enma told him which made Nasariu turn to his determination side.

"I understand Enma-sama I will give up whatever powers you want from me but not my Swords of the Necroverse or my jagan eye everything else you may take from me and as for my teammates are there any pacific to whom I may choose?" Nasariu stated his claim and asked for any rules.

"Sharp as always Nasariu-san but yes one of them must be a documented spirit detective and the other has no restriction so choose away!" Both Nasariu and Enma hated the council with a passion because they had destroyed innocent lives of loyal and trust worthy demons for just being in Reikai on assignment. This news meant Nasariu strike back at them.

"I choose Yusuke Urameshi and an old friend of mine Kazuma the Shell Bullet!"

"Heh, excellent choice but you know the council will be at your throat by the way Kazuma isn't he the one who caused a dimensional disturbance six years ago?"

"Yes that's him he is actually really powerful though his only power is connected to his soul and needs earth to create."

"Very well gather your necessities wile I summon your new teammates be back here in an hour." Enma said sending him off as he was thinking to himself. 'The boy has grown so much but will he be able to do this or will take this the wrong way and justify it as more than a test?'

Nasariu returned to his home that he had lived in for seven years and was almost sad that he was leaving. But he could not cry not now he had to be strong if he weakened it would mean the end of all life in all universes.

He walked down to his study which half the room that could take up a small village was filled with books and the other half was filled with machinery that he had created for the protection of the universes. As he flipped the lights on a see through entity that looked like a beautiful woman with long flowing blue hair that almost looking like agitated ice. She wore an equally blue kimono that looked absolutely stunning on her.

"Nasariu-sama it is good to see you have returned is there anything I may do for you today?"

"Beatrice-chan (be-a-tris) compact the lab and store yourself in the main hub we are moving load everything in to the travel pack and when I'm settled I'll release the lab and you may do what you like till I need you again! And what have I told you about being formal we known each other for four years now there is no need for that." Nasariu said as Beatrice disappeared and all the machinery began to fold flip and shrink into a small capsule and landed in a large travel sized backpack.

Incase you were wondering Beatrice is not some program in a computer but more like a digitized soul who he saved.

Flashback

Nasariu was sitting home one night reading the history on the Necroverse that no life my survive except pure evil souls anything with good would die in a matter of thirty minutes when a thud came at his door. He ran to his door to find a beaten and bloody young lady that looked like she was on the verge of death.

"NANTEKOTTA! LADY ARE YOU OKAY?" he received no response from her.

He rushed her to the lab and using upgraded models of Ningenkai's medical technology he scanned her body to find she wasn't human but a Korime demon she was dieing from a loss of blood and mutable contusions and stab wounds.

Looking at his options he found the only way he could save he was to place her soul into a completely new body which even with all his technology there was no time or he could digitize her body and soul into his computer with an invention of his that digitized books to put its information into the data banks to cross reference it later.

And he did just that it saved her life but and she was completely grateful for it. He offered to make her a new body but she refused and from then on she became his data tactician.

End Flashback

Nasariu condensed all his lively possessions into his pack then left his home. Taking one look back it brought back old found memories from all the years of living there and one small tear ran from his pupil less red eye as he continued off back to King Enma's palace.

Upon arrival he saw Kazuma and Yusuke and their wives Keiko Urameshi and Kanami Yuta standing before Enma waiting for Nasariu. He knew they would not leave their wives even for a day he knew they would bring them.

"Nasariu-san glad you have returned I have briefed Yusuke and Kazuma on the situation and they have accepted as long as they bring they're wives but I was waiting for you to come along to tell them the rest." Enma said as Kazuma and Yusuke got confused from the situation.

"I understand Enma-sama please continue."

"Right, Yusuke Urameshi, Kazuma, Nasariu-san has chosen you to accompany him as his teammates on his twenty year mission but do not worry about your worlds as time will pass differently there so it will only be a week that you are gone also your ages will be reversed so that you are five years old." Everyone's faces paled as he said this.

"Enma-sama why must we become younger? Kazuma asked bluntly.

"Good question, the boy you must protect is no older than five there for you must be his age so there is no suspicion to others of your mission!"

"Makes sense I guess sorry but I'm not too smart never been to a school in my life." Kazuma said rubbing the back of his head blushing slightly.

"Yusuke-san half your power will be taken away and you will receive a chakra system to replace that power taken but you will have to train to gain more chakra to be able to use it, Kazuma-san your Alter powers will be sealed off at each stage so when you are strong enough to access them same as Yusuke-san you will be given a chakra system and you'll have to train as well, Nasariu-san the same goes for you." Enma proclaimed as black energy rapped around the five's bodies.

After the energy subsided Nasariu looked at Enma with a new look of determination in his eyes. "Enma-sama I swear that is all of my being I will not fail you!"

"I know you will not but there are four more conditions that I have not told you yet." Enma said gaining their attention.

"And what might that be Shinigami-sama?" Yusuke asked before Nasariu could ask.

"Yes right to it then Kami has been informed of this mission so he has given four thing to me for you, number one you will not be able to die if you take a death blow you will be sent into a coma for six months, two if all have the ability to transform back into your older aged forms for thirty minutes once every seven days powers excluded and finally Kami has ordered me to give this scroll to you Nasariu-san I have no idea the contents of it but he has assured me the last two gifts are inside." Said the tubby overlord of judgment.

"Thank you Enma-sama we will make you proud of us!" the young king of demons said taking the scroll.

"Well this is where you should leave I have provided a house for you all to live in and there are a few surprises for you there call it a thank you for saving my futomomo eight years ago so prepare yourselves and GANBATTE!" The kind hearted Shinigami shouted as a portal opened up right in front of them. "Oh! And one more thing don't seek out the container of Kyuubi for two years that is all now Go!"

The trio walked through the glistening void and vanished from Enma's sight.

'Those kids will do wonder for that plain of existence but maybe I should have told them Necromancers and Shadow Beasts have leaked to that world as well oh well they'll over come it they are special kids with the power to defy the cosmoses itself.'
