Shadow Light

Chapter 1

Beginning with a Bang

After the conclusion of the fourth great shinobi war, Uzumaki Naruto has proceeded with his life and was made the seventh Hokage of the leaf village after some years. In those years he married Hinata Hyuuga and had 2 children. Boruto Uzumaki and Himawari Uzumaki. After achieving his dream of becoming the Hokage of the leaf village and maintaining peace and passing the hat to the next generation, Uzumaki Naruto lived a peaceful life with his family. He had become the jinchuuriki of the new Juubi, Kurama. All the bijuu merged with the Kyuubi and created the new Juubi. Kurama already regaining his other half of chakra after the fourth great shinobi war was colossal. But now merging with other Bijuu simply made him a gigantic beast. Keeping his original features of orange fur and red eyes with black slits in them he also had a third eye with a 6 tomoe Rinne-Sharingan in it. That eye will always be closed unless it is required. During his remaining time after retiring from his hokage duties, Naruto mastered all his new abilities because becoming the Juubi jinchuuriki like his dōjutsu, increased physical strength and other skills. He got all the 3 legendary dōjutsu, Byakugan, Sharingan and Rinnegan and his Rinnegan was special. Just like Sasuke's, his Rinnegan also had 6 tomoes in them and because of his limitless chakra, he can activate and deactivate his tomoes in the Rinnegan. He mastered them in his free time after retirement. One of the most important thing he attained by being the Juubi jinchuuriki was 'eternal youth'. Which in other words means he is immortal now. He won't age. But to keep things moving he used genjutsu like Tsunade to appear like an old man.

When he told about this to his wife Hinata that he was immortal and can't die she smiled and said "That's fine Naruto-kun. I got my wish of being with you. If I die I ask you to move on and find love in others. I know how lonely you felt in your childhood without your loved one's around, I know that you can't live alone without anyone. So, please Naruto-kun move on. If you like someone then express your love to them how you did to me for the first time. Promise me Naruto-kun, you will move on from this life." He promised to her that he will move on with his life. That brings us to the present day, where Hyuuga Hinata is being buried. She passed away a few days ago due to old age as they were 100 years old. He tried to prolong her life as much as he could but in the end, they reached her limit and she passed away. He stood on the Hokage monument looking at his home village for the last time before his departure.

"What did you plan Naruto," asked his friend and partner Kurama.

"I plan to leave this world Kurama. As the world is at peace, there is no more requirement of me or you here Kurama. We shall move to a world where peace is necessary and shall attain it there. With the techniques, we have with the Rinne-Sharingan I can positively say that we can go to a world where we are required. What is your opinion on this, Kurama?" asked Naruto as he stood on his head on the hokage monument.

"It's your wish Naruto. As Hinata said it is time to move on as this world is in peace and there is no requirement of you or me. Where shall we go Naruto?" asked Kurama curious as he wants to know what Naruto's plan to go.

"I don't know where we will go Kurama. But I'm certain that we will go to a world full of adventure" said Naruto with excitement. As he wants to go to this new world and explore it and if need be he will bring peace to that world as well.

"Are you ready for our departure Kurama? Hold tight. We're going" said Naruto with excitement practically dripping from his words.

"You got it Naruto," said Naruto and prepared himself.

They both channelled their chakra into their third eye and a black portal opened in front of them. Naruto stepped into it and behind him, it closed. And so Uzumaki Naruto, The Nanadaime Hokage(Seventh Fire Shadow), Hero, Father, Husband and most of all, a man who saved so many lives and remembered as the strongest shinobi to ever grace the elemental nations was gone.

(Scene Break)

Dimensional Gap

The Dimensional Gap is the gap that exists between the three worlds (Earth, Heaven, and the Underworld) and is considered a void world.

Nothing can survive within the Dimensional Gap without magical, demonic power or other protection. Anyone without such protection dies within a matter of seconds after being exposed to the "nothingness" within the Gap.

The Dimensional Gap is an endless void, wherein in every direction, there is a mix of iridescent colours.

As Naruto came through a portal to this empty void he felt it's immediate effects. He felt like his skin is being burnt from inside. Without any hesitation, he opened another portal and jumped into it.

Somewhere in Tokyo

It is night time in the city of Tokyo, Capital of Japan and most of the city is decorated in the colourful lights of the night. In a dark ally on the outskirts of the city a black portal opened and came a man. He was thrown on the grass and rolled on the ground before stopping by bumping into a tree.

"Ouch." Naruto groaned. He didn't expect that he will come to a place where the instant he was ejected from the portal he would be burned. Though he knew that nothing would happen to his body because of his healing and regeneration abilities he didn't want to risk it. So, he immediately came to this place. As he slowly rolled on the ground and straightened himself with the support of the tree he saw a man in front of him. This man is tall, appearing to be in his twenties with an average build, black hair, golden bangs and black goatee. Looking at him curiously.

"Hello there. Are you the one that opened a portal and came of out nowhere" asked Azazel with curiosity oozing in his tone? Naruto couldn't answer as his body is still recovering from that place and nodded.

Azazel looked at him curiously. In front of him was a young blond man looking like in his late teens maybe 17 or 18 and on his face were 6 lines like whisker marks and has fair skin and is at least 6 feet tall. He is looking like suffering from some kind of pain and is likely to die because of whatever he went through. Azazel got an idea. He searched through his goatee and took out a ball. Which is half black and half white. He kept it on the blonde's chest and waited for any reaction and it worked like a charm. With a blinding light, the said ball merged into his body and the blonde kid immediately healed.

"You okay there kid. It seems that my device worked" said Azazel with barely hidden amusement. The blonde looked at him incredulously.

"What did you do now. I'm going to heal from it soon you know. That black thingy is not required. If you didn't see I'm healing myself before you put whatever that ball on me." Said the blonde kid exasperated.

"Woah woah. Calm down kid. I didn't kick your puppy. I just helped you recover fast that's all. But, you should be thanking me because without my help I'm sure you would have dead soon. Anyway, leave about it and tell, do you feel any change in your body. Like light-headed or drowsiness or any other changes. Tell me" asked Azazel with excitement. If his research was successful then this kid is going to be one of them.

"What now. No I don't...feel an..y..ch..an..ge." suddenly to both of their surprise Naruto's body lit up, and orange, white and black colours glowed simultaneously like a light bulb and dimmed down slowly.

"Woah. What was that? I feel lighter now. Hey old geyser what did you do to me?" asked Naruto with tick marks appearing on his face. Azazel scratched his left cheek sheepishly and replied.

"You see. I'm a scientist and I experiment on sacred gears and in some cases create some. The ball I kept on you is one of them which contains two different elements which are light and shadow/darkness. I used the holy light used by angels and the fallen angels and combined it with the soul essence and power of a powerful shadow dragon named Skiadrum on his last wish before death. Which in turn should give you the power to use both light and shadows. And by the looks of it, my experiment was successful. Congratulations kid, you now possess a sacred gear which is on par with the mid-tier Longinus and a dragon type one to boot. Your sacred gear's name is Shadow Light." Said Azazel with his chest puffing out in pride. With this result he can proceed to add this in his list of successful experiments and work on his own with Fafnir.

For Naruto, it is like listening to a math class. Which means he didn't understand anything. But he could feel more lighter and his awareness about his surroundings had increased. While this old geyser was talking about himself Naruto asked his trusty partner about this.

"Kurama, you can feel it right. That ball gave us something related to light and darkness like this old guy told and you can sense his power right. He is strong. Though he is surrounded by something dark his intentions and personality is good. What do you say Kurama, shall we go with him and learn about this world or venture on our own" asked Naruto eyeing the guy in front him waiting for his partner's reply.

Kurama thought about it for some time. He can sense Azazel's power and he is strong and he can also say that something did happen when that ball merged with Naruto as he is currently getting information on soo many things. He can say that consciousness of someone is being transferred to him currently. 'Maybe these belong to that Skiadrum that this guy told about' thought Kurama. And he seems to be a good person. So he made his decision.

"Go with him Naruto. He looks like a knowledgeable person and we also should know more about this 'Sacred Gear' thing and this guy seems to be our best option." Said Kurama in a matter of fact tone. Naruto gave a mental nod.

"Hey, old geyser. What now. Sacred what" asked Naruto playing the role of a dumb idiot maintaining his expression in a feign ignorance. And it seems like it worked.

"Ah. I'm sorry, kid. I forgot about you. If you want more you can come with me and I'll explain more about this" said Azazel confidently. Naruto nodded and they both left to where Azazel lives in Tokyo.

Scene break

Azazel's House, Tokyo

After Naruto and Azazel settled down in Azazel's house Azazel began.

"To tell you from the beginning about the history of this world I need to tell you about the supernatural world's history first" said Azazel in an all business tone. To which Naruto nodded.

"The Three Factions were created from the power of the biblical God or God of Bible a religious God on this planet. When first created everything was good going, all the angels were following his orders and living peacefully but one day Lucifer one of the first angels to be created had a disagreement with the God and took his followers and left heaven to raise war against the God to take the thrown of heaven from him. He shed his angel wings and replaced them with the wings of a bat and at the same time some of the angels of heaven committed one of the seven deadly sins of lust, sloth, greed, envy, wrath, gluttony and pride and fell from grace from heaven and became fallen angels with the wings as black as night signifying their fall from grace. Most of the fallen angels under the leadership of me formed an organisation called Grigori and inhabited in the underworld otherwise called as hell and had a conflict with devils on the territory. And so began what now called as the The Great War. During the war all the three factions of Bible fought ad.gainst each other for so many things. Devils fought to capture heaven and dethrown God under the leadership of the four great satan's, fallen angels fought with devils to get in the good grace of the God under my leadership and get back to their position back in the heaven and angels fought under God's orders to save humanity from the supernatural world and to maintain peace in the world. The Great War lasted for several millennia resulting in the drastic losses to all the three factions. First we, the fallen retreated as I saw no point in continuing the war any further after that both devils and angels also retreated creating a temporary truece. But the damage already done. Because of the injuries suffered during the war the original four satan's Lucifer, Leviathan, Beelzebub and Asmodeous succumb to their injuries and died. And even the God of Bible died because of his injuries making Michael new leader of Angels and the protector heaven. This is a classified information. So, I suggest you, not to tell this to anyone as it's impact will be devastating on the three factions. And to my faction we suffered great losses in our number and are recovering from our losses.

There used to be 72 pillars of the devil clans which came into existence after Lucifer made creatures which are opposite to Angels in every way of speaking literally and figuratively. He created a new race who are oppossit to light and named them devils the opposite to angels. He with 3 others became the first 4 leaders of the underworld went by the name Maou or satan. All devil's are in a way his children with his wife lilith but because of different people having different powers, they had formed into clans based on abilities. There were 72 at the beginning but because of their participation in the great war it was declined to 39 clans and even the death of the original satans didn't deter their children from making plans to go to on other factions. And when they were making plans on how to make their attack all the other pillar clans opposed to the idea as they feared that this may lead to devils as a race's extinction and so formed into an anti satan faction and so the civil rahed for some years resulting in the victory of the anti satan faction and exiting the children of original satan's to the outskirts of underworld. The four strong devils who played a great role in victory were made the new satans of the underworld and led to a peaceful time in the underworld. Now let me explain you about the surviving pillar clans which were again declined to 27 if I remember correctly. The first and foremost clan is the Bael clan which holds the rank of 'Great King'. Famous for their poser of destruction which erases everything from existence if mastered, they are a fearsome clan" And the list went about all other clans which are Agares, Bellial, Phenex and so on. But Azazel didn't say about 4 specific clans and he continued.

"And this concludes about the explanation of all devil clans expect 4 clans whose former heir's became the 4 great satan's of the under world. Those are Gremory, Sitri, Astorath and Glasya-Labolas. The current strongest devil known as super devil and the Maou Lucifer Sirzechs Lucifer is from the Gremory clan with Venelana Gremory(neé bael) as his mother from whom he got the Power of destruction. Serafall Leviathan formerly sitri, the maou leviathan who is responsible for foreign affairs uses ice magic. Ajuka Beelzebub a former member of the branch family of the Astaroth clan is genius who invented the evil piece system and another super devil. He has created the famous Kankara formula which was said to bend the reality and finally Falbium Asmodeus from the Glasya- Labolas clan who is the physically strong enough plough through buildings reinforced with magic. These are the satan's and the strongest devils said to surpass even the original 4 satan's. The evil piece system created by Ajuka Beelzebub helps devils to reincarnate other races into devils. This system is based on a chess game. So the pure blooded high-class devils can reincarnate humans into reincarnated devils to bolster their numbers. Angels also have same type of system but, it is in the form of Deck of cards. All the seraphs has their own decks. We fallen angels doesn't have any such system as angels fall from heaven and we can have 'our' children to our ranks to increase our numbers and my effort of creating artificial sacred gears is one such attempt to improve our strength" said Azazel. Though it was a lot of information to take in, Naruto took it well but he had one question for this man.

"Why are you telling all this to me. I'm new here, but you didn't need to tell me all this as I can say that it consists some important facts like death of the Biblical God and some other things. For all you know about me I'm a stranger came out of nowhere and may use this information against you or something" asked Naruto incredulously. He can't understand why Azazel is saying all this to him a stranger who came out of nowhere. Azazel simply smiled and replied.

"You are correct. I don't know anything about you. But I'm telling you this as a way me, myself, reminding all the past that happened and I can tell that you, don't know about this world by the way your entrance. As it serves 2 purposes of giving a detailed explanation of history of this world and remainding myself my goal to achieve peace to this world and I can say that you are powerful from the power I can feel coming from you. If I can make you an ally that will be good for everyone in the future." Said Azazel with a neutral tone. During all his explanation Naruto didn't feel any kind of malice or animosity towards any other faction or any disrespect neither disdain towards the man who casted him out of heaven nor any pride in his achievements in his life or his position as a leader of fallen angels. He can say that this man is powerful and intelligent and if he is telling all this to him and deduced that he is going to be an valuable ally for future Naruto knew that he had some kind of plan in mind to use him in future. He can't help but appreciate Azazel's straightforwardness. He was used to being respected and admired as a war hero and leader of the village during his reign as Hokage and after war in Elemental Nations. As a fellow leader he can appreciated a fellow leaders attempt to gain an ally by being straight forward and so Naruto came to a conclusion. Azazel is good with wordplay and his intentions are pure that means he is doing this for everyone not for any personal gain.

"Yes. I can use a person like you as an ally as you know more about this world than me." Naruto said smiling and continued.

"For giving me that sacred gear and 'reviving' me as you thought, I'll give 2 favours. As for my allegiance, I'll wait for a while to accept that proposal. I want to explore this world and know how it works for myself and speaking of my sacred gear, can I conclude that you have a plan to train me how to use it yourself as you are very interested in making and using them" asked Naruto innocently.

Azazel smirked at this development. He thought Naruto would be intelligent but he didn't think his intelligence to be this sharp but he can conclude that the man in front of him was indeed powerful and with the addition of his new sacred gear he is going to be monster in future which just a added bonus for his allegiance if he decides to ally himself with them and as for other way around if he didn't ally himself with them, he should think some thing about it in the future but from the looks of it Naruto is good person and he concluded he will decide for the best. Azazel nodded his head to Naruto.

"Yes, I personally intent to train you in the use of your sacred gear Shadow Light. I'll agree to your terms, Naruto and hope for the best" said Azazel in a calm tone and extended his hand as a gesture to finalize their agreement Naruto also extended his hand and both men shared their hands coming to an agreement. They both nodded their heads to each other entering they has a consensus.

"Now that is out of the way, let me explain you about your sacred gear. Your sacred gear Shadow Light as I said earlier is made from two elements or rather sources. One being the soul and conscious of the Shadow Dragon Skiadrum who in his last moments asked to use his remaining conscious and energy to make a sacred gear to remind the world of his existence and other being the pure light energy which angels and fallen angels use. As I was making it I got an idea of mixing both elements one being made of pure light and other being made of shadows, darkness and void. And the result is that of the sacred gear you have know and as there are no backlash on you I can conclude that it is a success. As for you using it l, even without any training you should feel familiar towards all the shadows and light particles in the environment." To which Naruto nodded as he can sense a familiar feeling towards everything around even more so, as it is night time from his connection with shadows. Azazel continued.

"Shadows can used in a number of ways and I can tell me some but there are special techniques belonging to the shadow dragon himself if you search with in your self you can find his conscious with you giving you all the knowledge and you can train with that knowledge yourself. I can help in training you with the use of light energy. As I'm one of the best to use light energy and as for the strength of the light items you make it will depend your heart. If you are pure enough it will be strong but none the less it will be as strong as that of fallen angels. The purity comes into play if you want make your strongest. Your strongest light spear will be as strong as that of a 12 winged angel or fallen angel. If you don't have any questions then we can begin your training immediately." Said Azazel curiousity and excitement brimming in his voice as he his pretty much excited to test his newest creation. Naruto can understand Azazel's curiosity and nodded to begin.

And so began his training in the use of his new sacred gear Shadow light.

And Cut.
