The Reincarnated Shinobi - Sasuke Sitri

Chapter 1 - Sasuke Sitri

The sound of metal cut through fresh flesh could be heard under the eternal purple sky of The Underworld. Above, two moons were shining eerily, trying their best to show way to the resident of this world. Such a thing was unneeded however as Devils have better eyesight than human and also the ability to see in the dark.

A silhouette of a teenage boy could be seen holding a sword in one hand and a decapitated head in another as he stared down at the now, dead, general. He was breathing heavily, obviously in need of oxygen after the hard battle with the Stray Devil General.

'So this is the power of an S-Class Stray Devil…' Using a simple magic, the black hair teen sealed away the head which would later be used to increase his payment for the mission. Falling down, the teen allowed his body to rest a bit before continuing his part of the mission.

After defeating about 10 or so Stray Devil all A-class and their leader who was an S-Class, he couldn't find a single drop of energy within him anymore. Such was the power of an S-Class. Reaching out his hand like he was grasping something in the air, the teenage boy clenched his fist in determination.

"Stronger. I need to be stronger than this. This isn't enough." The boy mumbled to himself as the fire of determination and unwavering will burnt brightly in his charcoal black eyes. In order to become the strongest, in order to protect his family and those close to him, he needs to be stronger.

Stronger than even the Four Satan and stronger than even Great Red.

Such a thing was considered foolish and insane considering how much power the latter had at its peak. A being lives in the voids, the space exists between dimensions and has the power to completely erase the existence of those who are foolish enough to anger it. But, would he just give up knowing his goal was considered impossible?

No… He isn't his old self anymore. He wouldn't give up on something just because the odds were against him. He wants to be like his best friend, the man who had united the Elemental Nation and archived his dream of becoming Hokage, Uzumaki Naruto.

He had already wasted his past live as Uchiha Sasuke, he didn't want his second chance to be wasted too. He would try his best in this world and live a life with no regret as the heir of the Sitri Clan, Sasuke Sitri.

'Master, we have successfully captured the East Gate. What is your next order?' A stern feminine voice said in his head, cutting Sasuke of his thought. Currently, he and his peerage were taking on an S-Class mission which was to capture the traitor Diodora Astaroth.

His Knight and his Bishop were to attack and capture the East Gate while his Rook would take on the Front Gate to attract attention. After the enemy's force had thinned out in order to reinforce the two gates under attack, he and his Queen would assault the West Gate and then, went inside to deal with the traitor.

Apparently, Diodora had somehow, figured out his plan since he and his Queen had encountered a group of high level Stray Devil there. Urging his Queen forward to finish her part of the plan, Sasuke himself had to take on about 10 High Level Stray Devils which was led by an S-Class. Needless to say, he was dead tired after that.

'Oy, Sasuke, can you send me some reinforcement? I'm having trouble at the front gate!' Another feminine voice said in his head. This one was different from before, it was more upbeat and energetic which suits her wild personality. It belongs to his only Rook, who was no doubt fighting an entire army by herself.

"Hang on, Kotori, Ultear and Soujiko are coming to your reinforcement." Sasuke ordered calmly and stood up. After sending out order to his Rook and Bishop, the black hair teen picked up his sword and ran into the castle, looking for his Queen and the final Boss.

-Diodora's Castle – Front Gate

"DIE!" A stray devil shouted out as he thrust his spear at a cute girl with red eyes and very long light coral-colored hair, however, the most eye catching thing was a pair of horns sticking out of her head. She was wearing a white kimono which resembles a goddess's robes from Japanese folklore, with a revealing neckline, a translucent sash, and black ribbons tied around a pair of horns.

The girl sidestepped the attack easily before slamming her huge, flaming halberd into the body of the devil. The force behind the attack blown the stray devil back along with those stood around him. The girl raised her weapon high into the air before unleashing a long wave of fire with an overhead strike. The shockwave resulted from the attack thrown back several devils who thought surrounding her would be a good idea.

Dragging her halberd – Camael behind, the girl ran on the road which had been opened by her attack earlier through the horde of Stray Devil, ignoring various injuries she received during the way. Her eyes shone brightly as she smirked at her target who she assumed to be the leader of the army.

"STA-STAY BACK!" The Devil shouted while firing spell after spell at the girl who skillfully evaded the energy bullets before jumping high into the air, her halberd ready to steal away the life of her target.

"Die." She whispered before bringing Camael down, cutting the devil into 2. All around her, the surrounding devil could only stare in shock and fear at the death of their second in commander. She, who stood amidst a sea of corpse with a sadistic smirk on her face while bathing in the blood of her enemy was Itsuka Kotori, the Rook of Sasuke Sitri.

"Pathetic! Is this all?" She said, obviously looking down on all the Stray Devils there. Here and there, blue flame appeared on various place on her body, healing all the wounds she had received, leaving behind a completely fresh Kotori when it finished.

"Monster…"

"How the hell can we beat her!"

"Ah… we are done…" Hearing various whispers around her, Kotori's excited expression turned into one of disappointment. When her King tasked her the mission to capture the front gate and fighting an entire army, she had hoped that they would have at least some formidable devils to entertain her… but guess not.

"DO NOT FALTER! KEEP YOUR DISTANCE AND USE YOUR MAGIC!" A Stray Devil shouted out loud as he himself prepared a medium size magic circle to attack Kotori. He is probably the real commander of this army as all the others immediately did as they were told. A smirk formed on Kotori's face as she pointed her halberd at him.

"Camael! Megiddo!" The halberd still remained in her hand, however, the blade had disappeared, replaced by a cannon. Kotori smirked at the Stray Devil Leader who shivered in fear when seeing the huge ball of fire inside the newly transformed cannon.

"Turn them all to ashes, Camael!" A large energy beam of fire was then unleashed upon the Stray Devil Army, devouring all who stands in its path which include the commander earlier. Immediately switching her weapon back to its halberd form after preemptive strike, Kotori blocked a water spell that was sent her way. The red hair girl gritted her teeth as she blocked spell after spell sent her way by the vengeful stray devil army, unable to continue her attack.

The situation had been reversed she guessed. While she is stronger than ALL of these Stray Devil combined, Kotori's doesn't have much fast pace long range attack. She could use Megiddo, but it would take too much time to recharge and she doubted her mana could keep regenerating her under this rain of spells for long.

The fight came to a stalemate after that as the Stray Devils kept raining spells after spells on Kotori but none could hope to break through her defense and regeneration while the Sitri Rook could only advance slowly.

But still, the cute girl maintained a confident expression on her face. After realizing that she would be in trouble when they switched to attack from afar with their magic, she had contacted Sasuke for reinforcement. Her allies were coming for her and then, the battle would be on her side again, she just needed to wait for that to happen.

As a servant of Sasuke Sitri, she had absolute faith in her King and also her allies who she had fought through many battles with.

Soon, the sound of clashing could be heard coming from the East. Two figures could be seen running toward Kotori's direction while killing off every nearby Stray Devils. One wielded a katana with such grace and effectiveness that her enemies couldn't do a single thing to stop her while the other used her Ice Make Magic to open the path and keep them from being attacked from afar.

A confident smirk appeared on Kotori's face as she realized that her few friends had come to her reinforcement. Taken by surprise by the two's arrival, some the Stray Devils stopped firing their magic at Kotori, leaving enough time for the red hair girl to advance.

Realizing that her chance had come, the Rook of Sasuke Sitri began her massacre on the Stray Devils. Kotori charged forward, ignoring numerous spells flying her way and jumped straight into the heart of the stray devil army with Camael on fire.

"Cleave! Camael!" Channeling magic into her halberd, the initiative overhead strike caused the ground to crack and fire to erupt from below, sending the stray devil army into panic and confusion. Not stopping there, Kotori began her rampage on the panicking army, killing all standing in her way with her flaming halberd.

"Ice Make: Rose Garden!" A little away from the red hair Rook, Ultear Milkovich, the Bishop of Sasuke Sitri was also doing just fine. Slamming both of her hand on the ground, a wide magic circle spread out before numerous ice rose rise up, killing her enemies with its sharp, dangerous thorns.

Ultear is a pale-skin beauty with dark purple hair flowed smoothly on her back and several bangs covered her forehead. She also had a white head band and brown eyes. Her outfit consisted of little more than a tabard-like garment that barely covered her front and back, with a sizable slit exposing her cleavage. The attire was open on both sides of her body except for a small attachment at her waist, and she donned long black boots that left her upper thighs bare. She had a large X-shaped scar on her back.

Glancing left and right, Ultear took a moment to calculate her next move. The purple hair beauty raised her left hand and created a thin ice shield to block a sizable energy ball sent her way before hurling an ice spear back at her assaulter with her right hand. Slapping both hands together, Ultear increased her magic output, causing her body to glow.

"Ice Make: Ice Dragon!" Immediately, a large magical circle appeared beneath Ultear who smirked at the stray devil army who had unknowingly signed their death contract by stepping into the circle. The ground shook violently before a giant eastern dragon made completely from ice with shining red eyes emerge from the magical circle, impaling those inside with its sharp, spiky ice scales. The dragon soon began its rampage with Ultear on its head as it rushed through the panicked and disordered army.

Arriving with Ultear earlier, wielding a katana with white handle and wearing traditional Japanese clothing underneath a pale blue haori which has white triangle design was non-other than the only Knight of Sasuke Sitri, Okita Soujiko, daughter of the famous Okita Souji. She is a young girl with light blond hair tied behind her back with a large black bow, her fringe covers her forehead and 2 shoulder-length bangs framing her face.

Her eyes are of hazel colors but currently, they looks like cold ice as Soujiko slashed her way through the stray devil army, not batting an eyelash at all the bloodshed around her. Just like an efficient killing machines, she emotionlessly stole away the life of her enemies with each slash and each stab she made.

Soujiko tilted her head to the left to avoid an energy ball thrown her way before with a single step, she disappeared from sight only to reappear in front of her assaulter with her katana ready.

"Sandanzuki (Three-State Thrust)." As flash as the wind, the Sitri Knight impaled her enemy with three consecutive strikes, knowing he was dead even before his body fell down.

"You are slow... even when falling…" Nimbly, she ducked under a swing, flipping backward to gain some distance and then, throw herself into the enemy line again with eyes as cold as ice and katana already coated in blood.

She slashed, she cut, she stabbed and she thrust, every attack was made with exact precision and prediction that even if her target tried to dodge, it would still hurt them somehow. Soon, the once great army of Stray Devil of the Astaroth Clan was no more, the three Devils of Sasuke Sitri stood triumphantly, admiring their work while looking for each other's safety.

"Somehow, we managed." Soujiko said with a pleasant smile on her face while sheathing her katana after ending the life of the last alive Stray Devil. Her expression completely different from before now that her eyes had regained some light. Unlike a certain comrade of her, who always get excited when facing strong opponent or hard situation, Soujiko doesn't enjoy killing or even fighting, but when her Lord ordered her too, she has no choice but to seal away her emotions and cut down her enemies.

"They are all weak though…" Kotori said while massaging her shoulder which had gotten a bit sour from swinging Camael around too much. As always, her regeneration kept her fresh and unwounded as if the battle had never happened, but too bad, it couldn't clear her exhaustion.

"Say the one who calls for reinforcement cause she couldn't complete her task alone." Ultear said mockingly which irritated the red head Rook who glared at her.

"The hell did you say, Ice-Popsicle?" Kotori called while rolling her kimono's sleeve up and set her fists on fire. In return, Ultear created a sword of ice in her hand.

"Who are you calling that, you crazy bitch!" And with that, the daily bickering between Ultear Milkovich and Itsuka Kotori began. Soujiko didn't know if it was because of their completely opposite magic element or maybe because they were such best friend that they always fight each other… but it started, and it's normal for them.

Placing a hand on her head, Soujiko began to think about her King, her Master which was the key needed to use Telepathy magic. As a knight, she doesn't have much talent in magic but with the support of their Queen who acted as their 'server', she could freely contact anyone in Sasuke's peerage as long as she remembered how they look like.

'Master, the front gate has been subdued.' Soujiko said through the mental link.

'Good job, Soujiko. Stay there and protect our way back. We will come down there in a few minute.' Soujiko nodded before muttering a silent 'Roger'. Looking back at the red hair Rook and the purple hair beauty…

"Flat chest!"

"Boobzilla!"

…They were still at it. Soujiko let out a tired sigh before sitting down on the ground and picked a bag of Mochi out of her cloths before munching on them with a happy expression on her face.

-Diodora's Castle – Throne Room

The sound of a page being flipped could be heard clearly even amidst the sound of battle. There sitting on a large hovering book was Sasuke Sitri's Queen who was reading manga while battling Diodora Astaroth and his peerage. Flipping another page, a blush came to the queen's beautiful face as she read the romantic scene in the manga while imagining herself in such situation.

"What with that woman… she doesn't even pay us a single thought and yet… many of my girls have been killed..." Diodora said in disbelief as he stared at the majestic sight of the Sitri Queen. She is a woman with large breasts and her most noticeable feature being the two large gold-looking horns protruding from the sides of her head and pointing upwards. Upon her head is a white band which separates her hair, framing her bangs from her hair below the band. Worn upon her forehead is a small circular symbol with a small dot on the inside and surrounded by several dots around the top. Tied around her neck is a small white-colored strap.

Meanwhile, her attire consists of a very revealing beige-colored leopard-printed kimono, bearing the decorative marks on her shoulders. The kimono is wrapped around her torso with a thick, decorative yellow ribbon that ties behind her back, and her outfit is complemented by thigh-high socks that reveal her heels and toes

Said woman was battling against his peerage but all she did was sitting on her hovering book and reading manga. But even so, Diodora and his servants couldn't touch her because surrounding the Sitri Queen was various books of various size and covers which acted as her weapon and defense. Some of them were normal novel and manga Diorora could recognized, but others he couldn't. They look old and the words written on it was so strange that he couldn't make any sense of.

"Yah!" One of his servants jumped at the Sitri Queen but before she could bring her sword down, a book slammed into her face, causing the girl to fall down with a broken nose. Several books then appeared hovering above her body which caused the girl to stare at them in confusion before her eyes widened when all the books suddenly hurled toward her at great speed. A small crater could be seen when the assault ended, leaving behind the lifeless body of the Astaroth Servant.

"…So she choose to leave so that her friends could be saved… A foolish decision since her friends will still go after her when they find out the nature of her missing." The Sitri Queen muttered as she finished reading the manga in her hand. Snapping the book closed, the horned devil stared straight into the eyes of Diodora Astaroth while leaking her oppressive power into the air, suffocating those inside the room.

"Kneel." The Sitri Queen ordered and immediately, all the devils inside the room kneeled down, their legs just suddenly lost the strength to support their body. Diodora gritted his teeth as he tried to stand up or even lied down to crawl away but he couldn't. He couldn't go against her order, something was stopping him to.

'How! Just how can this happen!' Diodora thought to himself as he cried. How can the difference between him and Sasuke Sitri be this big? They are of the same age right? Then how can he gather such a strong peerage? How can that guy be better than him?

He couldn't believe it. His plan had failed, all the Stray Devils he hired had been killed and now, he had no doubt that he would soon, join them in the afterlife too. Looking up at the Sitri Queen who was still sitting on her hovering book, looking at him with impassive, merciless eyes, the traitor couldn't help but chuckle dryly at his misfortune.

"Any last words, Astaroth?" The horned devil asked indifferently but received no answer from the now, despaired devil.

"Now then. Faint." She ordered which caused all the evil in the room to drop down, unconscious. Obviously, she couldn't kill them since the mission demanded the traitor to be captured alive for further interrogation. The last time she killed someone without permission, their mission payment had been cut in half, resulting in a month of no new books for her.

"Seilah! Ah, already finished I see." Sasuke, who had just charged into the throne room with his sword in hand said with a smile on his face as he looked at his Queen who had already resumed reading manga and only offered him a nod. The young Sitri sighed before walking to the unconscious Diodora and tied him up.

"Mission completed. Let's go home, Seilah." With that said, Sasuke carried Diodora on his shoulder and jumped out of the castle while his Queen decided to be more elegance and fly down instead. They would meet up with the rest of their team at the front gate and then, they would all come home with a single teleportation.
