Chapter One: The Undead Man

A young teenager girl sits in front of the beach with a low whimper and she glance over her shoulder, staring at an aesthetic stone hut. Her eyes cast down at her white dress and a large ornamented cross with a sigh, she has been so alone because of her duty that has been thrust upon her the first moment she was born.

She clasped her hands together as she look up to the sky, "God…I do not want to be alone anymore…I-I want a friend…P-Please, grant me this wish…That is the first time I have been so selfish…" She look back to the beach sadly before she release a shock gasp as soon as something catch her eyes at the edge of the shoreline. A boy lie on the sand facedown as the wave wash over his body and she quickly run over to him, her barefoot dug into the sand with each step.

The boy wear a ruffled white shirt with loose brown pant, his blond hair matted down to his head from the salt water and he has whisker marks on his cheeks.

"Oh, dear!" The girl gasped worriedly and she quickly glance at the sea for any sign of boats before she pick him up with some struggle. She notice that he is taller than her by few foot but she don't pay any more attention to it in favor of getting him to the bed and change him out of his wet clothes before the poor boy catch fever. She can't stop blushing the whole day after she strips him out of his clothes, checking on the slumbering boy often.

The teenager girl fills the stone cup with rainwater from the large barrel and she enters the hut, glancing at the boy on the cot. She put it on the table with a click, following by a stirring groan and she turn sharply to the boy with a gasp. The boy struggled to sit up and she pushes his shoulders down hastily.

"Don't get up, mister!" She said, "You were washed up at the beach! Who know how long you have been out there!" She quickly takes the cup, handling it to the boy. "Here, drink."

"Arigatou." The boy drink the water with some difficulty before his eyes gaze at his surrounding, "W-W-Where am I?"

"Um, what?" The girl blinked puzzled, he speaks in different language and she doesn't really understand him. The boy frown to himself before he gestures at the surrounding with his arms and the girl understand instantly. "O-Oh, my home." She said clearly and slow before she point at herself. "Me…Eve. Your name?"

The boy look down in deep thought with scrunched-up face before he look up to her, "Naruto."

"Nathan?" Eve said.

"Naruto." The boy shook his head with a small chuckle and she blush at her mistake.

"Sorry!" Eve giggled sheepishly before she make some body signs, "What happen to you? How do you end up at beach?" She pointed at the sea out of the window and it seems like he understand her mostly.

"I don't remember…" Naruto tapped his forehead with a shaking head before he make a 'boat' shape with his hands, "I think I was on a boat but I'm not sure…"

"You forget?" Eve wiped her forehead with a tilted head as the boy nodded at her, "Oh…What else do you remember?"

Naruto widened his eyes and he look down at his shaking hands, he can't remember anything else but his name. She can't help but to feel sorry for him before she grab his hands and she bring them up to her face with a smile.

"It's okay." Eve smiled at him, "You can stay with me until you remember everything." Naruto don't know what she was saying but he smiles back, squeezing her hands in gratitude.

It has been few years since Naruto washed up at the beach and he has been living with Eve, much to her joy. It was difficult at first because they both speak different language, their genders, and the small hut but they become very comfortable with each other and he found out a few things about Eve. She don't have any family members, which is why she have been on her own for years, and she was guarding something that she can't tell him and he don't mind it. She told him a lot of stories about angels and God, among with devils and fallen angels, he wasn't sure if they are made-up stories or real story because they both haven't seen any person since he show up.

"Eve-chan, hang finish." Naruto said in broken English as he step inside the hut and Eve look up to him with a smile.

"Thank, Nathan." Eve grinned as the boy rolled his eyes at her nickname, "I'm almost done making the soup."

"Porridge?" He asked and she nod her head without looking up from the pot.

"Why do you keep asking me that, we always have it everyday." Eve shook her head before she gasp out with a blush as Naruto slide his arms around her waist and he rest his chin on top of her head. "N-Nathan!"

"I love you." Naruto hugged her with a wide smile and Eve's face bright up in deep red.

"I love you too…" Eve pecked his chin shyly before she swats his hands away from the streaming pie with ladle, "But you are not getting any slices until you finish your dinner!"

"Stingy." He rubbed his hand with a smirk before he run across her large cross with his fingers, "You want me make new one? This too big." The cross was two time large than Eve's hand.

"No, thank you." Eve holds her cross with her free hand with a sad expression, "I…It's important to me…"

"Precious?" Naruto whispered softly, he don't know why she become sad every time she look at the cross around her neck.

"Yes, you can say that…" She hummed sadly before her lover kiss her on lip, startling her.

"Don't be sad." The boy smiled at the blushing girl.

"D-D-D-Don't worry, I won't…" Eve blushed with a beaming smile, "Not when you're with me for the rest of my life."

"Hai, for rest of life." Naruto smiled.

He doesn't know what just happened. They come out of nowhere and they attack Eve and him with these light lances. Naruto gritted his teeth as the light lance stuck though his left knee and he glare angrily at the man with black feathered wings, this man hold Eve up by her neck. "L-L-Let her go!" Naruto roared angrily before another lance pierce though his right shoulder.

"NARUTO!" Eve screamed with tears running down her face before the fallen angel threw her down on the floor with a slam.

"Where is the elixir?!" The fallen angel barked at them as his allies ransack the hut, destroying it in the process.

"I-I-I have no idea what you are talking about…" Eve muttered before she cries out as the fallen angel smashes his foot down on her spine.

"You know what I'm talking about!" The fallen angel slams down again as he flicks another lance at Naruto's other knee, forcing him to drop on the ground. "The elixir that grants one the eternal life and immortality!" He narrowed his eyes at her with a leer, "And you are the chosen guardian to watch after it!"

"I-I-It is not real!" Eve growled out as her lover crawl toward them hurriedly.

"J-J-Just leave us!" Naruto grabbed the fallen angel's leg, "We just want to live in peace and…"

"NOT UNTIL I GET WHAT I WANT!" The fallen angel stabbed Naruto's back with a roar, "WITH THIS POWER, I WILL BE UNSTOPPABLE AND END THE GREAT WAR BY TAKING DEVILS AND ANGELS OUT!" He summon two lances in his hands with a dark look, "AND I WILL FORCE YOU TWO TO TELL ME WHERE IT IS!"

What happen next was a longest hour for them, he torture them in many way with just a light lance. He stabs their limbs and non-vital organs, he gorge some part out of them, he skin them, he tore their nails out, he did everything while laughing at them until he stare at their wringing bodies with a sneer.

"Tsk." The fallen angel clicked his tongue annoyingly as he form another lance over his head, "You humans are so stubborn, I'll give you that…" He threw the lance at Eve and it almost pierce her, if it wasn't for Naruto as he suddenly jump in front with a burst of adrenaline rush and the lance went though his heart.

"N-N-Naruto!" Eve screamed as he falls down next to her with a labored breathing and she choke out as the fallen angel throw another lance through her stomach. She shakily look up to see the fallen angel returning to his allies to search for the elixir and she quietly lift her cross up with shakily hands as she stifled her sobs. "N-N-Naruto, hold on…" She twirl the top of the cross and she remove the top part, revealing a tube filled with a clear fluid. She drink it all into her mouth and she crawl over to Naruto before she kiss him deeply, pouring the whole fluid into his mouth as he drink it by instinct. "I...Love…You…Na…" Eve's eyes closed with one last breath.

Slowly but surely, Naruto's injuries disappear as his missing part regenerate from nothing until his body restores fully and his eyes snap open with a dry gasp. He turns to Eve with widened eyes, "E-Eve-chan!" He cradled her in his arms, "W-What did you do?!"

"Yio!" A female fallen angel called out in shock and the male fallen angel, whom tortured and killed them, turn around to see the healthy boy with widened eyes.

"Y-You…" Yio gritted his teeth with clenched hands, "You drink the elixir?! DAMN YOU!" He threw a light lance and it rip left side of Naruto's head off but to their shock, Naruto's left side regenerate immediately.

"…You killed her…" Naruto whispered lowly as he rest Eve's body down on the ground gently, "…My sweet Eve…" His eyes sharply turn to them in a deadly glare, "YOU KILLED MY EVE!"

"KILL HIM!" Yio shouted and the fallen angels attacked Naruto with their weapons but it was in vain as the now-immortal boy attack them in rage. They even use their fists and legs to beat him down to drain him out but Yio slowly realize that something was off. Naruto was slowly getting stronger and faster each second while he slowly becomes weaker, the other fallen angels were in same boat. 'W-W-What is going on?' Yio summoned his light lance before he throw it at Naruto, 'I-Is that one of the effect from the elixir?'

"CHOP HIM TO BITS!" A bulky fallen angel swings his broadsword downward at Naruto, only to grasp nothing but empty air. "H-Huh…?" He uttered before his head lob off from a sudden swing and the broadsword was in Naruto's hand.

'Huh, how did he take it without us noticing?!' Yio watched on as the raging boy took some of his comrades out, '…No…It can't be…' "Y-You have a sacred gear?! B-B-But what kind of gear can rob our physical abilities and…" He never get a chance to finish his sentence as Naruto suddenly appear under his guard, cutting his stomach open with a swing of the broadsword before the boy punch Yio down and he give the fallen angel the brutal beating.

He did not listen to Yio's plea for his life as he crushes his fists against the fallen angel's face over and over. He did not stop when Yio's skull caved in under the stress, neither he didn't stop tearing his body apart with his own barehand. He refuses to stop because this bastard took Eve away from him! He has to pay for his sin! The beating continue for hours until there was nothing left but just a bloody smear on the ground with littering body parts and Naruto finally stop, kneeling in front of Eve's body in daze.

"E-E-Eve-chan…" Naruto was about to cradle her again but his hands froze in midair, he don't want to dirty her with the blood and he release a deafeningly wail as he bury his head in his arms on the ground.

Naruto stare blankly at the dirt patch under an oak tree on the cliff that overlook the hut ruin, it have been a week since he buried Eve and he never leave the spot since this day. "…Eve-chan, I have to be away for a bit." He whispered raspy as he tightened his hold on Eve's cross, "I-If the immortality elixir exist then there must be something that will bring you back…Maybe it's these sacred gears that these guys were talking about…" He touches a large stone in front of the dirt patch, "…Just wait, Eve-chan, I will revive you, no matter what…G-G-Good-bye for now…" He quietly walk away from the grave, making a silent vow that he will never stop and if anyone get in his way, he won't hesitance to cut them down.

The engraving on the stone read, 'Here lies Eve, beloved friend and lover. We will meet each other soon.'.

Into the first year of his journey, Naruto has accepted the existence of supernatural and get himself involved in the Great War for several reasons. His first reason is to collect some info on anything relate to resurrection, even if they are just rumors.

Second reason is to protect the helpless humans from these supernatural creatures, it really frustrates him to know that the innocents were dragged into the damn war and it remind him of how helpless he was back then. It starts when he visit a bar for info and there was three devils terrorizing the building by attack and torturing patrons until he step in and murdered them in front of shocked humans.

Third reason is to find out more about his sacred gear and why they seem to be important or feared by some people. His gear does not have any names so he call it 'Snatch' because it give him an ability to rob things from people and he found out that he can also steal their ability from strength to speed and add them to his own power. It have a drawback, there is a cap for his body to take the powers in until he train his body to take more in. He believes that the gear limits him to prevent the stains so his body won't either give up or blow up and if he makes himself stronger, he can 'steal' more. That was all he can find out for now.

And the final reason is to get revenge on the so-called three factions and end the war. Everyone is his enemies because he blames them all for Eve's death and he refuse to ally himself with any sides. If the war ends, he can easily find the way to bring her back alive without looking over his shoulders.

"I-It's the undead human!" A devil screamed out before Naruto thrust his hand through the chest, ripping his heart out as the immortal boy flick his whip at another devil in the distance and the whip somehow rip a heart out of the devil without any scratch.

"Move back!" The angel solider shouted back to his troop and his eyes widened as the immortal flashed in front of him before the boy cut his head off with a swing of his broadsword.

'It is all for Eve…' Naruto stabbed the nearby fallen angel in back as his left leg jolt out backward, kicking the roaring devil's chin out. 'I must kill them all…' His sword twist before it slashes upward out of the fallen angel, 'Kill them…Kill my emotions…' Dozen creatures jammed their weapons into his body but it doesn't slow him down as he kills them with stolen strength, 'Kill myself! Kill myself! Kill myself!'

"H-H-He's a monster!" The bulky devil shivered in fear as she watch the boy stabbed his sword into the downed angel and he was kneeling on a hill of corpses.

'That's right, I'm no longer a human.' Naruto's eyes become dull and lifeless as the light fade out and he calmly stand up, facing the armies with blank face. "That's right, I am a monster. The one you all created…"

The war went on for many years and the three factions have lost so many people, mostly due to Naruto's ruthless nature, and they give him many names. Undead monster, undying human, heart stealer, and many more. No one, aside Naruto, knows why he targets everyone indiscriminate or his reason to get involved in the war. Some brave souls attempt to bring him to their side but he refuse by outright attacking them, even if some just want to lend their hands to him out of good intention. They all indirectly agreed on a rule to not to fight him and flee on sight or forfeit their lives to him. But on a certain day, there was a battle that they can't flee from and little did they know is this day will be the last day of the war…

Naruto walk into a large battle calmly as the creatures decking out with each other and several soldiers foolishly target him before they realize him as the undead human but it was too late for them. "Where are they?" Naruto use his whip to drag a female fallen angel toward him before he slashes her in half with his sword, "The Maous and God."

He appears to be in early twenties, stand at nearly seven foot tall and he wear black shirt with armored pant. He has five different types of swords on his back with a whip at his hip side and some soldiers can see that he was well-built with muscles.

"Y-You bastard, how did you know?!" A devil shouted at him with widened eyes and his response was just a swing of sword that took his head off.

"It doesn't matter." Naruto stepped over the headless body, "Just show me the way." No one give him a reply as they charge at him with battle cry and he walk through the barrage of attacks, ignoring the pain since he has been numb to everything after he killed his own emotion.

"Ugh, m-my strength…" The angel dropped down on the ground with several angels, devils, and fallen angels.

"I-I-It's his damn gear…" One of the devils growled out, suddenly choking on his blood as soon as Naruto jabbed a thin sword through his lung on his way.

He continues to walking toward the middle of the battlefield and the first thing he sees is two bloodied figures, standing over a body with another two bodies nearby.

"F-F-Finally, God is dead!" One of the standing figures laughed out loudly, "I, Lucifer, have slain the god!" He turned to his comrade, "Asmodeus, send the word out! The devils are now…" Lucifer's eyes widened as Naruto appeared at their side with a beating heart in his hand and Asmodeus drop dead. This human just killed a Maou! How can it be possible?

"Here goes my lead." Naruto said flatly, "Now I have to follow more rumors for…" His head explode from the blast, courtesy of Lucifer's dark magic.

"Tsk, now I have to replace three…" Lucifer turned away from the headless body before his eyes widened as the sword burst through his chest and he shakily look over his shoulder to see Naruto with his head. "H-H-How…W-W-What kind of magic is…" He never get a chance to finish his sentence as Naruto rip his sword out with a upward slash and the immortal quickly cleave his head and part of torso off with a downward slash. "N-N-No, I am Lu…"

"And now the Maous are dead." Naruto turned away from the corpses, walking across the battlefield as he ignores the shouting of armies as soon as they found the bodies of their leaders. He would later find out that the Great War end in a ceasefire and he start to focus on the info of resurrection more.

Many centuries have went by since the end of Great War and Naruto can't find the way to bring Eve back, which drive him into deep depression because Eve's body might turn into nothing but skeleton. He have been on move for many years to hide himself from the world and he went though many events that take place in history while meet some people, always drop by her grave every year to make sure that no one move her body as the world develop into modern world. At some point, he starts to remember everything about his life before he was found by his lover. He comes from a place called Japan and he was a fisherman who went out on a trade route until the storm hit his boat. His family was long gone, due to time.

Right now, he is currently in a certain town in Japan and the name of the town is Kuoh.

Naruto sit in the park at night and he watches humans with dull eyes. He wears a white t-shirt, black pant with shoes and a bundle on his back, his appearance barely change at all. 'The world really changes so much…' Naruto thought, he always thinks the same thing over and over when he watches people living their everyday life.

"Hi, you look very lonely." Naruto glanced up to see a smiling attractive blue-haired woman, "Would you like some company?" She purred seducingly.

"Fuck off." He said bluntly and the woman's face scrunched up in rage at his comment.

"W-What?!" She hissed angrily.

"You hear me." Naruto replied, "Fuck off, crow."

The woman's eyes widened at him, "Y-Y-You…How?"

"I said…" Naruto send a heavy killing intent at her, "Fuck. Off!" The woman quickly took off after the sudden burst of KI and he return back to his people-watching. "…That place is crawling with devils and fallen angels…"

Naruto walk down the street in the morning as the people glance at him in awe, they never have seen a tall man in their life before. 'Everything is pointless.' Naruto sighed, 'There is nothing for me to do but to hide and wander around…Until these pests come after me.' He enter the park and he walk past a sighing boy on a bench. 'Another devil.' Naruto feel the familiar aura around him before someone trip in front of him with a cry. He look down to see a girl on the ground with exposed white panty as a head cloth covered her head, somehow tangled with her blond hair.

"Ow, ow…" The girl winced, "Why did I trip?" The boy was about to get up but Naruto hold his hand out to her.

"You alright?" Naruto asked dully, his emotionless voice creepied the young devil out.

"Ah, yes!" The girl spoke in Italian, took his hand as she fumble around with her veil, "Thank you very much…"

"Here…" The immortal fixed her veil as he help her up and he look at her face for the first time before his eyes widened.

"Oh, thank you very much!" The girl smiled beamingly.

"…Eve-chan?!" Naruto whispered in shock.

"Huh?" She blinked at him confusingly before she smile again, "Ah, sorry! I think you must confess me with someone else. My name is Asia Argento."

And that end the first chapter of UH?! Love it? Hate it?

Naruto have same abilities like Ban from Seven Deadly Sins. He is an immortal who have lived for over thousand years and he have been involved in the Great War and he killed two Maou! Well, they were weakened from the battle to be fair and Lucifer underestimates him because he doesn't know that Naruto is immortal.

Naruto will not become devil or angel, he will stay as a human!

The pairing is strictly Naruto x Asia.

How will it change the HS: DXD with Naruto in it? Let's find out in next chapter!

I think that's all I can say for now…Thank you for your time to read it.
