AN: lemons in here... a fair warning...

After the usual rain, and steady even grey silver clouds unleashing. The sound of seagulls echoed across the waters; waves crashed against the few remaining rocks. Some of sirens were awakening, coming out as they appeared like dolphins. Then the loud screech filled the air around with their moanings…

- "Aww…" the sirens moaned as a singing came out from their throat.

The new day broke out, fishers would start their day while others were already on the lake; some got too close.

- "A pack of dolphins!" one of them yelled, while they went around and saw them.

They were observing as the banshee sound could echo on the waves, they realized there was something else on the waters, so they watched closely until something slowly started to surface, a head filled with long white hair came out of the water, and two big black eyes opened, stared up at the crew of only three. A chilling silence crept over the men.

- "Captain, it is a girl!" one of the crew yelled at the captain who was trying to manage the big waves on his boat.

- "Their ship must have sunk from the mist!" the captain replied.

The crewman could not take his eyes off the mystical black eyes. While the third stated that there is no way there were other ships at this early in the morning. The captain came down and finally unrolled a rope which then splashed next to the figure on the water.

- "Climb up darling, get yourself out the old!"

Nonetheless, one of the men noticed something odd, her nose and mouth remained under the water, how she could be breathing. But the captain insisted, and as he was puzzled on her black eyes, when she then lunged out of the water and wrapped her arms tight around the captain. They both noticed she had grey purplish scales continued on to the bottom where she had sharp fins instead of feet. The half fish slowly lifted her head to face the confused sailors and revealed to him her jaws of shark with razor like fangs and hungry eyes. As the sailor let out a fearful scream, the creature opened her shark like jaws and snapped them shut on the captain ripping in clean of his face.

- "Fuck, get the kunai!"

In seconds another siren came onboard as they both devoured them alive and the ship sunk, they were feasting, drinking from their blood. More came through as the blood stained the waters until there was not a single more drop.

In the midst of this, a new creature was awakening, there was no denying that he felt feverish and sick, but he also felt an odd sense of pride. Naruto had one siren kissing him as there was no end, their tongues tangled, arms wrapped around one another. Naruto loved how warm she was, while other ones were reaching from below, grabbing their hands over him, and pushing him down her throat. Naruto moaned as he was being taken care of.

{Our master, the wielder of the Samehada, the king of the waters} the voices echoed as the sirens moved closer once again.

The sirens were releasing fluids that made the water muskier, around him catalyzing Naruto's changes, making him grow as the shark of the waters. Samehada was integrated with him. As sirens were licking and caressing his powerful tail, Naruto felt how the siren was touching his refined abs, his thickened biceps and triceps.

In the mixed euphoria of pain and pleasure, the waters around then was thicken as Naruto was smelling the sex through his gills. Suddenly, sirens from the surface went down to where Naruto was, they were carrying blood and flesh as they broke Naruto's kiss, and made him kiss them. The iron taste was slipping down his throat. The wave of energy that was released was immense. Naruto suddenly felt awake alive, like he'd jumped off a bridge into a frigid lake. His eyes widened.

- "What was that?" Naruto whispered back as he felt his doble razor fangs.

{Blood mixed up with chakra, Samehada feeds on your victims, the power of eating a soul} another siren came by from his back, whispering on his ears.

- "And it will keep me feeling this way?" Naruto asked hopefully as his clawed webbed hands moved once again.

Another siren moved closer to him, grabbing his head as she moved in for another kiss. Naruto's mouth bulged wide as more chakra began getting poured into his gullet, further giving him the stamina he needed.

- "Hunger… " Naruto whispered the words without being capable of finishing a sentence.

{You now belong to the infinite spiral, the spiral that goes down into the depths of power and pleasure, to the infinite spread of all bliss} the sirens echoed as they moved closer to him.

- "Go and feed…" they whispered.

Naruto's shark instincts got the best of him. He used his fins to push against the water, stretching the sea weed before it snapped. He fluttered around before swimming up towards the shore. His toes had grown longer than his fingers, the flesh between stretched out into long flippers tipped with deadly talons. Naruto's body glistened with a rich royal metallic blue, as he moved further. In moments he was approaching the beach, as his changes subsided and he was taking a more human shape.

Triangular grey fins cut through the white foam on the surface, massive forms moving just beneath. Naruto had grown a muzzle with sharp teeth, his tail was sharp, as he moved further. Initially, he reached the first ship closer to him. (AN: In this shape, he became as the story picture)

- "Something is in the water!" someone on the ship shouted, backing up. While he retracted, other men advanced. A column of water lifted up, the sunlight shining through to illuminate the figure within before the water cascaded across the deck. As the water spread out, Naruto stood up to an impressive eight feet tall, looking around with his eyes.

- "RRRR…" Naruto roared as he jumped and killed everyone. His claws grew longer as he was having a feast; He felt complete.

Then, Naruto left the sinking ship as he moved to the shores. Slowly Naruto was retracting as a human once again, and as he emerged, Naruto was taller than before, from his chin down his throat and across his stomach, his flesh was almost perfectly white. The flesh on his shoulders, back and face had taken on a richer bluish grey. Naruto was wearing a skin-tight sleeveless black wetsuit that came up to his knees. He was fully shaved. His hair was white and messy as it reached down his waist. His teeth were shark-like. Behind him, he was carrying Samehada coiled across his torso. Naruto noticed his claws never subsided. His hitai-ate was of the Mist country on his forehead.

In his mind there was no Kyuubi, but a collection of sirens singing to him, guiding him, but what really changed him was his hunger. It was messing up with him, he loved blood but also the chakra, so vast, so think, so juicy and so spice, and Samehada was feeding off him, so he should get his own…

- "Hoshigaki" said one man as he fell on his back.

Naruto looked at the man, and suddenly the small town near the dock felt a great coldness. The gaze was completely inhuman, devoid of all emotion and human feelings, filled with a cold cruel logic. Suddenly they all dropped their knees and began praying in a strange language, the angels, the sirens had come back, so the religion was true.

- "Am I hoshigaki?" Naruto wondered when he was faced to the true.

Naruto continued as he moved through the forest, in route to Konoha.

(In Konoha)

It past a few months since Naruto disappearance... Right now, Sarutobi was behind his desk doing the thing that he hated the most: paperwork. He did not know why but he believed it had the power to reproduce like mice. An hour later he had only finished half of the paperwork, he took a break and looked at the village through her window.

This last week was very quiet with Naruto gone, not even Konohamaru was doing more pranks. Sarutobi was worried sick he could not find the brat.

Nonetheless, outside Konoha, walking down a dirt road, Naruto was walking after training with the sword alone, he carried it banded it up on his back, with almost his height. His black eyes were watching just as the gates were coming closer and closer to him. His forehead showed the Mist Hitae-ate.

When he reached the gates, they found that the gate guards were fast asleep. Naruto chuckled at this before signing himself in. While walking through the village, it was obvious that the villagers noticed him, they looked on in fear. There was some sound of metal piercing flesh, blood was emanating from nearby the entrance. Cries filled the air as he stalked deeper into the village that was once his.

Naruto felt his pulse rise, he had not felt that before upon a battle, the bloodlust was gaining more control out of him. There was a mob, made out of a dozen of them at least, they were all chunin by what he sensed, and each seemed strong. Funny enough, after analyzing them they were wearing different clothes, as if they were from a different village, truly they were Suna ninjas. Something must have happened between the two villages while he was gone, but he had no clues, he had never seen them before.

Naruto could not hold back, he had to act, and he did instantly, moving through the air quickly he grabbed one of them and kick him on the abdomen throwing him over a few meters away. Another one who was surprised at the attack, attempt to throw him kunais, but Naruto ducked them and shot scales from his right arm.

- "Stop this already, motherfuckers!" Naruto yelled as the demon Samehada was guiding him, removing all of his feelings and making him feral like the sirens.

Suddenly, a burst of water came from his arm, being very pressurized it shot to the shinobi. The shinobi did not even have a chance to draw the breath to scream, his side was blown away, the pressurized water removed it instantly. The entire village went deathly silent in a heartbeat. The leader spun on his heel and gazed with certain surprise at the reborn Naruto.

Naruto's teeth grew as well as the scales on the Samehada, passing through the band that covered it. They all wanted to feed on the flesh, on their chakra.

- "How did you kill him?"

- "A kekki genkai, of sorts. Forgive me, but I must now remove you from existence," and in saying so Naruto grabbed Samehada, the heavy sword seemed light and agile for Naruto, the scales grew bigger and bigger.

In a barely an instant to register Naruto's vanishing, before one fell, sliced in twain from hip to shoulder, blood and bone exploded everywhere, and dyed the earth red. The shinobi leapt back, yelling in surprise and fear. Naruto spun and fired other scales from his arm, stabbing some of them. Naruto needed speed, but Samehada was slowing him down, the sword needed to sometime to shallow the three corpses it had eaten off.

- "I must end this here and now" Naruto whispered.

Naruto leapt forward, the ground cracking beneath his feet as he shot forward like a thunderbolt. The shinobi turned away in the nick of time, but the leader was not so lucky. He fell to his knees, when Naruto's fist was embedded in the leader, who was impaled to the wall of the nearest house. Blood ran from the man still clinging to life. Naruto ripped his fist from the man, while he then ate him out, just like the sirens had thought him, eating away the chakra, feeling the burst of energy flowing into him.

Slowly Naruto's eyes fell on the Suna woman, she was staring at him in fear and horror, her breath rapid and terrified. She shakily began to turn and run. Naruto watched her go dispassionately. He moved over and grabbed his Samehada, he twirled it in his hand, and threw it at the feeing woman. The blade shot scales through the air and cut her down, impaling her like a spear, sucking all of her blood and fresh as it was devouring her.

- "Ah…" Naruto moaned as he felt his sword had eaten as well.

Naruto turned and strode back through the village until he stood before the lady with Sameheda impaling her and ripped it from her corpse in a spurt of gore. He watched as the blood was absorbed into the sword and felt the satisfaction of the blade.

- "Thank you…" Sarutobi said from the distance while he watched the fight, he did not know he was speaking with Naruto. Naruto was quietly grabbing his Samehada back on his back, while he was watching the jiji-san coming over.

- "However, we owe you a debt of gratitude. How can we repay you?"

- "You're a newcomer, food and bed?" Sarutobi said while he then looked at his whisker marks.

- "Yes…" Naruto answered. Apparently the Hokage could not recognize him with his new skin and sharp teeth.

Naruto was placed into the Hokage Tower, and he was offered simple but wholesome food. Naruto tucked into it with a ravenous delight. Everyone gazed at him with surprise and mild amusement around the Hokage's office.

- "You look rather similar…" Sarutobi said as he was observing the creature in front of him.

- "Are you… Are you… Naruto…?!" Saturobi said in surprise as he got up from the table.

- "It took you a while oji-san," Naruto smirked.

- "Samehada…!" Sarutobi whispered.

The sword with tons of purple shark teeth like blades over it, made to ripe and shave the targets to shreds. The sword with the uncanny ability to feast on chakra even from the distance. The sword had found a wielder in so many years of absence. It all made sense, the murderous sirens were back, but now they were not; Naruto was not in the water.

- "You have come out from the water!" Sarutobi had so many thoughts.

- "No way!" Naruto said sarcastically.

The Hoshigaki Clan, a clan made of females with one man, their leader, the clan has been extinct for so many years, it was a come back. They were feral and sharkish, out of their mouth would sprout a weapon that was prone to them. The Hoshigaki were the god and religion to the Land of the mist, they praise them. The Samehada became its signature weapon.

Naruto got up, as a chakra wave came out of him, plunging the room into cold. He glanced up and the pressure vanished.

- "Did you have any remorse or regret from killing them?" Saturobi asked.

- "No," Naruto said as he was ready to leave.

- "I killed them because I wanted to"

- "Naruto…!" Sarutobi said as he was about to leave the office.

- "What's with you?" he asked.

Naruto stopped as he could see the sword almost reaching twice Naruto's teenager height, almost covering most of his back. Naruto turned and faced Sarutobi, when then Anko came through the window, the word spread quickly. Naruto noticed Anko, and he caught the girl, and pinned through the wall. Naruto roared slightly, holding the girl in his left hand. Anko who had been through worse, but she was afraid.

Naruto pulled the girl closer to his parted jaws. The girl let out a small whimper and closed her eyes, waiting for the inevitable feel of jaws chomping down on her head and sharp fangs digging into her scalp.

- "Stop! Let her go, right now, Naruto," Sarutobi said while the girl was anticipating an attack that never happened, what she felt was a wriggling tongue and dripping fangs.

- "You. Smell. Power" Naruto said before letting her go.

- "I want my sirens on the surface, Oji-san," Naruto said. "We want to come back on the land…"

Sarutobi was cold in the uncanny response from Naruto, as Anko gagged and breathed again. Nonetheless, the best way to keep potential enemies under control was to keep them close, so that Sarutobi said quickly.

- "I want you tomorrow in the training grounds, Kakashi will be waiting for you and you're going through the exams!" Sarutobi said firmly as he wanted to see what he was made of anyways.

- "Hmph" Naruto smirked before he left the office.

Naruto left the office as he went on to explore the village he had left, walking down their roads, it was obvious that Naruto stopped by the ramen post. Naruto had a giant grin as he ate his bowl of ramen. Ayame was a little unsecure, but she continued to place a bowl in front of him.

Next to him, there was a ninja called Hinata, she missed Naruto for the month he was gone, so she promised to eat ramen occasionally. When Hinata took her seat next to the shark, she was only able to part her lips slightly before a massive blush developed and her eyes slowly grew.

Naruto felt the presence of Hinata next to him, she was horny, and as Naruto turned to see her, she turned bright red. She gave an almost audible gulp and stuttered when she asked for her ramen.

- "Are you OK?" Naruto asked with a grin.

{The first siren must have loved you, she is dripping wet} the sirens echoed.

Hinata attempted to control herself, and after a few hours, it was getting late and Ayame had to close up the shop. The two ninjas left.

- "Good night," Hinata said as she knew he was Naruto but she was completely scared of making any moves.

- "Hold up, Hinata" Naruto said, Hinata turned to look at her crush, recalling he remembered her.

- "Do you want me to walk you home?" Naruto smiled at the proposal, but he knew his intensions.

Hinata blushed and giggled quietly before nodding her head. The walk was nice and quiet. Naruto walked Hinata to the entrance to the Hyuuga estate. As soon as he let her go, Naruto grabbed her and pushed her against the fence. Hinata was speechless, there was no time

{Let me possess her, release me} the siren sang onto Naruto's mind.

Naruto's tongue slowly started to slide across her smooth, silky neck. The adrenaline started pumping through her body as Naruto reached to her mouth. Naruto slowly wrapped his arms around her, pulling her in closer causing their bodies to collide. Hinata in ecstasy had completely surrendered her body to him. Naruto slowly sided his left hand over Hinata's body.

Finally, Naruto pressed his lips to Hinata's. Hinata's eyes went wide as she was kissed, something cold, wet and dark was reaching into her. Naruto could taste Hinata's chakra right at it, it was something warm, vibrant, something pure. Naruto could taste her soul.

Naruto deepened the sinful kiss and began to explore Naruto's mouth with his tongue, starting to draw in the energy he felt just beyond. Hinata was paralyzed in Naruto's grasp as she felt her soul start to drain through her lips. Her lips grew cold and turned blue, her eyes darkened slowly. Even her skin grew pale as Naruto drank the soul in. Naruto drank and drank, feeding on the soul, pulling it out of Hinata.

Once her soul was gone, Hinata was void, Naruto licked his lips slowly swallowing the last of the soul into himself. He had never tasted anything so good in all his life. Naruto groaned sharply as he felt the heat of her chakra.

{She's mine…} The siren whispered as a black ooze came out from Samehada.

Naruto was drinking her soul, Naruto drank and drank, sucked feeding on the soul, pulling it out of Hinata, she was getting emptier. Once at that moment, Samehada oozed a black fluid from the whole sword, it was coming out from it and slithering to Hinata. The ooze was flowing into her lower orifice, as the sensation she felt was like a feeling of thrusting.

Hinata was gasping with short moans, as the ooze continued into her mouth, the living fluid poured down her throat. She choked and gagged to Naruto. Hinata drank in, as she then passed out. Hinata moaned as her pupils reverted as well as her fangs, the strength of Hoshigaki was within her now, the lust and the predatory instinct of hunt.

- "Syrene…" Naruto knew her name.

Over that night, Hinata slept without remembering really what had just happened. Hinata was at a distance in his conscious, as the siren spirit was within her, unfolding, coming out from between her legs, lifting up as an oily shadow, trying to take a shape before tendrils began pushing out. The tentacles were sliding on the sleeping body of Hinata.

(Lemon Warning - )

Hinata moved a bit in the bed, scratching at the tickles, still not fully awakening. She did not feel, but the spirit wanted to be certain and feeling bolder, the sea oil sent out thicker tentacles, tracing her chest, circling on her nipples before stroking them.

- "Uhgh…" Hinata murmured starting to stir more. The siren loved Hinata's body, she wanted her to be one with her.

A thick tentacle pushed out curving and slithering around, taking the shape of a long organ that brought it true life. With little warning, the tentacle plunged down and spread Hinata's mouth wide, sliding back and forth in her mouth before going deeper. It teased and pulled, stocked and stretched, getting the nubs to grow out as long as it could.

{We are the siren consort} the voice echoed in a sleeping Hinata, she dreamt of killing in the sea, she was a monster, her two rows of teeth make her bloodlust.

Hinata saw how she was killing those sailors, that was the siren consort herself, killing for her beloved, defending the sea from impostors, fucking them to kill them and feeding on them. The feeling was electrifying, sending sparks throughout. She was indeed a killer. Her body began to burn in hunger, looking for death and blood.

- "Awww!" Hinata moaned as she woke from what she thought it was a nightmare, but the oily tentacle was still sliding back and forward in her throat, making her impossible to alert others in the Hyuuga estate.

The spirit felt emboldened by the drastic moves, by her awakening from her sleep, and tried to regain shape. A clawed webbed hand made of a mist pulled out, then another. Hinata was hallucinating. She saw a shadow of herself, in front of her was herself. The shark fins were obvious, it was more than a mermaid. As the creature freed herself even more, her claws grew longer and thicker, as well as her details. The siren moved over to Hinata, pulling out the tentacle from her mouth.

Hinata suddenly gasped, her chest rising and falling as she tried to reclaim her breath. She was about to scream out for help, but her eyes were glued to the siren in front of her. The siren came down to sit on her lap. Hinata could barely feel any weight but she could feel the touch of wet, cold body against her. The siren massaged her breasts with her clawed hands, as the tentacle came back, plunging back into Hinata's mouth.

Hinata did not resist, somehow, she knew it was her, that face was her, it was herself, and she would never hurt her. She sucked, running her tongue down to whatever she had in her throat. The siren tipped her head back and let out a silent moan, basking in the pleasure. The siren writhe and shift her weight on Hinata, reaching out to caress her head. As the siren stroked her hair, the color drained from it, turning it white, making it long….

{This hair is poisonous, it is armed with nematocysts, contact with it can trigger millions of nematocysts to pierce and poison} the voice said as her hair grew till her waist, covering most of her bed.

The siren shuddered, feeling Hinata's body so close, the siren began to stroke her arm, making it stronger, leaving out the white pale into a dark grey, darker than Naruto's, the creature began to sink into the flesh. Veins turned from red to black, bulging before the muscle grew.

As the siren pushed her left hand into Hinata's arm, the two seemed to start bonding. The siren leaked out over Hinata's arm, growing and hardening like stone, becoming a black armor of shark scales, similar to Samehada. The scales coated her forearm until it finished with webbed clawed hands.

{Your scales are razor sharp, capable of piercing and cutting through} the voice said.

Hinata let out a louder moan. She had never felt anything remotely as impressive as the bonding, but she was start to worry. Why was this happening to her? Hinata started to fight the pleasure, to doubt the siren. The siren grunted as her arm snapped off, leaving Hinata with a new arm and the siren without an arm. The siren used her spare hand to stroke Hinata's chest, that they were one…

Hinata used her tongue and cheeks to slowly pushed the member from her mouth. The siren pulled the tentacle back to its normal shape, looking at the human carefully. Hinata said nothing, merely closing her eyes , leaning down. In a moment of a sudden pause, the siren came closer and their lips touched and a shiver moved through them both. Hinata let the softness wet creature fall onto her, letting and kissing in desperation. Years of lust were spilling out. For the first time, Hinata did not feel alone, she did not feel weak.

The two continued to embrace, but both could feel a rising tide of energy between them until, without a warning, the siren's face wrapped around Hinata's. The kiss ended abruptly as the shadow formed a fac covering her face. The black molded onto her like clay, stretching her ears like ridged. The oily substance slipped over her forehead before rising into two firm horns, claiming the consort title among the sirens. As Hinata's eyes opened, a blackness covered them, her eyes would never close, her lips were inexistent so she would always keep an eye on her prey.

Without a head, the siren on top of her began to spill and splash across Hinata. The torso collapsed across her chest, the veins of her right arm bulged before a matching arm filled out there as well. The oily substance began to cling to Hinata in desperation, latching on so hard that her human body could not take it, her skin turned white on her chest as her breasts grew, becoming firm and rounded.

The former siren's body also covered her legs, making them smooth, similar to a shark's skin, before capping her toes with talons. She panted hard, gazing up t the ceiling with her black eyes, as the siren's mentality seeped into her own. Memories came flooding into her mind, the memories of the sirens… its lifetime of playfulness, of killing and of bloodlust, of her master, Naruto, the king of the sea: Hoshigaki.

(To be continued?)
