Summary:

Kazuto and Asuna both dies in the real world, in 2026 due to the Maximum Acceleration, instantly once it started. Informed about the future collapse of this world by the 'Author' due to the Soul King's death. They are given a chance to save the world, and come back to 2026. The chance was simple: Return back in time, to 1897, within the Soul Society… With only tidbits of warnings about Aizen and Yhwach… And the key to defeating these all, they return back.

Here's the following things you'll need to know:

This = Zanpakuto speaking This means speaking in monologue or to Zanpakuto.

I don't own bleach, Tite Kubo does. Reki Kawahara also owns SAO, because if I did EugeoxTiese would be a thing.

Rated T until any sort of fluff scene occurs.

Chapter 6: Entrance

As the Shinigami was about to yell out his release, Kazuto and Asuna both used flash step, and leapt towards him, interrupting Izumo's incantation.

Asuna's rapier came first, forcing him to block her straight charge. Despite the clear opening for counter attack, Izumo simply used his Zanpakuto to block what he sensed was another incoming attack.

With a burst of speed, Kazuto appeared before him, as Izumo had predicted, as he swore: "Tch! Filthy Rukongai brat!"

Their swords collided as sparks were caused by the power the two had put behind it. Kazuto's slash versus his own unsealed version of Rhitta.

As he leapt back, attempting to curse at them, he was caught by an relentless onslaught from Asuna, forcing him to constantly dodge as she unleashed yet another combo of attacks at him.

Izumo felt the pain as the cold metal of the Katana striked his face, ripping out another cut onto his already cut out face.

He felt annoyed, annoyed not because of his own powerlessness but at the pride-less actions of these Rukongai individuals.

They didn't care about honour, they didn't even let them release his Shikai. How dare they! When I go Shikai… I promise them a slow death, instead of a honourable one.

I shall end this.

He cursed yet again for not being good with kido, being with the 11th division. Izumo was no good at kido, and in situations like these, Kido was needed.

"Switch, Asuna!"

"Hai, Kirito-kun!"

Immediately after the onslaught from Asuna, Kazuto switched into her spot, as she leapt back to recover stamina and disengaged from Izumo whilst Kazuto attacked from the back, forcing Izumo to change his attention on directions once more, slowly causing more and more fatigue to Izumo, as Izumo was forced to dodge.

Despite his reflexes, he still was once again cut on the torso, albeit not deep. With the pain and fear of more wounds causing him to leap back, Kazuto pursued relentlessly, going in, as he used the movements for the strongest one arm sword skill combo in SAO: [Nova Ascension].

Going in first for an overhead slash, Kazuto moved swiftly, forcing Izumo to counter it, similarly to what the administrator did during her fight with Kazuto: A frontal attack.

Rebalancing himself, as he engraved his footprint on the ground, Izumo cried out in fury as he faked counterattacking Kazuto with his strongest strike.

As the slash went down, he grinned, causing Kazuto to notice something was wrong.

It's like that time… The fight with Quinella.

XXXXX

Izumo grinned as he saw through the weakness of t1he commoner's attack. It's emphasis of an overhead slash and straight charge left it straight open for a fake counter-attack, then with an attack via stabs, he could injure the boy.

This'll teach him.

Instinctively, as Izumo's blade went close to Kazuto's Torso, Kazuto dodged, as the blade cut through his clothing, causing a small cut.

Izumo growled as he continued his attack, with a left handed uppercut towards Kazuto's torso, forcing Kazuto on the defensive.

Kazuto cursed as he focused on blocking Izumo's strikes. Blocking isn't my style… The Aincrad Style, no… The Black Swordmen's style is to beat my opponents with my unstoppable combo strikes! And now… Now I have to retreat.

As a heavy uppercut from Izumo, knocked Kazuto's katana and arm out of position with it's sheer force.

As Izumo went for the finishing strike with an overhead slash, he noticed his opponent calling out: "Asuna! Now!"

Dammit! He called the whore behind me. I'm going to have to try and escape… I'm shit at Kido… But it's my only choice.

"Hado 1, Sho!"

As Izumo stopped his slash and leaped back whilst not turning his body, he pointed his finger towards Asuna, a thrust of force came upon her, as it pushed her towards a wall, causing a small crack as she collided with it.

"Asuna!"

However, with his attacks stopped due to Asuna, Kazuto used flash step as he managed to inflict an upper cut slash at Izumo's torso, causing him to bleed out heavily, as Izumo leapt back.

"Tch! Damn you Rukongai boy!"

With one hand holding onto his wound, a medium sized cut stretching out from his stomach to shoulder, he was pursued by Kazuto, who spoke nothing as he attacked relentlessly.

"You leave me no choice! It hurts my pride to have to do this!"

Izumo lifted his arm from his wound as he saw Kazuto leap towards him.

"Hado #4! Byakurai!"

Kazuto adjusted his blade as he saw the lightning bolt go towards him, preparing to slice it apart. Just like GGO, huh?

"The speed of a spell like that is no match to the speed of a bullet from an Anti Materiel Rifle!"

It's actually faster… Dammit! But I can block this, I can do this!

Yes, yes you can! Go my hero.

Slashing down his sword, using the overhead position he had prepared to use against Izumo, he slashed down against the kido, which exploded in his face, forcing him to leap back.

"Asuna! Now!"

Asuna leapt out from her position as she leapt towards Izumo, who grinned. "Too late!"

Izumo raised his sword in the position used for an overhead slash, as he panted out the words he had tried to paint out for ages.

"Strike! Rhitta!"

Flames surrounded his Zanpakuto as it turned into an axe. Kazuto growled as he looked at the axe, whilst Asuna just sighed as she stopped, as they both said together: "That's Escanor's axe…"

"From the Seven Deadly Sins."

Izumo pointed his axe towards Kazuto, as he growled out: "Cruel Sun!"

A fireball generated from the tip of his axe, as it flew towards Kazuto at incredible speeds, forcing Kazuto to dodge, whilst Asuna continued her charge towards Izumo.

Using the back of his axe to block, Izumo managed to block Asuna's strikes successfully, as he laughed with pride: "A Shinigami with Shikai is five times stronger than one without! To know your swords name is to know your own power!"

Kazuto spat out in disgust, as his flash step's distance suddenly increased several fold. "Then we don't need to hold back another… I was hoping not to go all out since we had to attend the entrance exam soon… Asuna?"

Asuna nodded as she leapt back. "Yeah, let's release the seal then."

They both yelled out: "Gintei Kaijo."

With their own self-imposed seal limiting their powers to ten percent of what it was, now lifted, both of their body's aura's now flared incredible Reiatsu. [1]

Asuna leapt back, as Kazuto went in for an uppercut slice towards Izumo, who laughed as he smashed down Rhitta. "There is nothing Rhitta cannot cut! You merely kid yourself when you say you're stronge-!"

Slashing apart Rhitta, Kazuto continued his strike, as he saw the fear in Izumo's eyes.

"Please… Please don't kill me! I beg for mercy, I'll give you my rank, I'll give you anything!"

Kazuto was tempted… He was tempted not to kill Izumo, as his will wavered between killing or not in the last moments of his uppercut, ready to cut into Izumo's Aorta.

If I let him go now… If I don't kill him. It'll be like in SAO and Underworld. Kuradeel. Laughing Coffin. Gabriel. PoH. Quinella. Chudelkin. People who I care about will suffer. I can't let Asuna kill him. I can't let her suffer the trauma I did. I'll protect her!

[2]

Gritting his teeth as he made his final option, clutching the wooden hilt of his Katana, as his hands felt the pain of the power he had put behind his clutch of the hilt, Kazuto made the uppercut slash, as he dealt the final blow to Izumo, killing him.

As Izumo fell to the ground, his eyes went white, whilst his Zanpakuto dropped to the ground, now broken, as it began fading away.

With a red stain on Kazuto's face, which was Izumo's blood, he sheathed his Katana and turned away towards Asuna.

As tears dripped down, Asuna saw the pain within Kazuto's eyes. "I'm… I'm sorry, Asuna… I had to do it."

Kazuto placed his head down on Asuna's shoulder as she hugged him. "It's alright… I understand when you had to kill. The Kirito-kun I know… Is still there. He'd do anything… To protect me. So it's my fault, Kirito-kun. I know about the PTSD you had from Shino, so please… Don't put all the blame on yourself. You saved me when you killed Kuradeel, you saved 200,000 souls when you killed Vector, Quinella and PoH… So don't hate yourself, Kirito-kun."

"Asuna…"

Asuna smiled as Kazuto looked at him straight in the face. "Let's carry each other's burdens together. No matter what, promise me."

Kazuto smiled, as tears fell down.

Drip, drip.

"I promise… Asuna."

As the two's lips came together, the soul of Kazuto Kirigaya lightened, as his burden, his memories. They were all comforted by the one sentence spoken by his lover. The fear of rejection, the fear of unknown was gone.

"Thank you, Asuna… I love you."

She smiled as they separated their lips. "I love you too, Kirito-kun."

Seireitei, 12th Division SRDI Complex.

"Captain!"

The blonde man walked towards the horned, bald researcher, as he lazily rubbed his eyes, in his nightgown.

He yawned out: "Why'd you call me up so early, Akon-san?"

A thing with a black and white face painting, and an overall inhumane facial structure simply snatched the papers from Akon, as he said to Urahara: "There's a weird signature from the Rukongai, see for yourself"

Mayuri handed the papers to Urahara, as he the blonde genius looked at the papers, and on it were the Reiatsu patterns of the the 1st to 10th districts.

Akon continued, as Urahara looked through the 1st District of the Rukongai. "Akon-san this is… A ninth seat being beaten by two unknown 3rd seat and 4th seat level Reiatsu's…?"

Akon nodded as Urahara shook his head and grinned. "Such unusual spiritual patterns for the Rukongai's residents. it isn't a hollow or Quincy, but akin to that of an unlisted Shinigami. Ma, ma. Looks like we have work cut out for us, let's get to work."

Urahara grinned as he smiled goofily to Mayuri: "Kurotsuchi-san, could you lead a team to investigate?"

The scientist huffed as he replied snottily to his superior: "Hmph. I'm busy. Go do it yourself, or get the monkey to do it."

A voice was heard from the back: "What did you say, baldy?!"

Urahara sighed, as he called in a hell butterfly. "Call for the ninth to investigate, they are the Seireitei's guards after-all."

Ninth Division, Captain's office

"Kensei-kyun!"

Kensei growled at the mention of his name by his lieutenant. The annoying green haired brat, who still had enough power to boost of her rank.

That didn't mean he had to like it.

"What is it, Mashiro?"

"The 12th sent us a message, it's about the burst of spiritual pressure last night in the 1st district."

Kensei gave a rare grin to Mashiro, as he replied to her: "Tell them it's nothing to be worried about, they'll soon know why."

Mashiro nodded as she darted out of the room to call a hell butterfly.

So, Kazuto Kirigaya, Asuna Yuuki. You both managed to easily beat a 9th seat in Shikai senseless. And from what I felt last night… It was Kirigaya-san who did most the fighting, albeit Yuuki-chan is just as strong. These next few years ought to be interesting. Looks like I better get ready for the Captain's Emergency assembly in relevance of claiming prodigies.

Kensei allowed himself a grin, as he looked out in the window. "This will, be fun."

Entrance of Shin'o Academy, Seireitei.

Kazuto and Asuna, waited in the line as the entrance examination staff passed out the tickets inside one by one.

"Byakuya Kuchiki."

Asuna sighed as she saw all the girls fawn over the young boy. She and Kazuto both heard of the word 'Kuchiki'.

The five great families, and he was the grandson of the famous Captain of the 6th, Ginrei Kuchiki. The boy had long black hair, with the traditional Kuchiki headwear which the heir or head of house were meant to wear.

Kazuto shook his head in disappointment, as he said: "Ah shit, here we go again… Isn't that headwear the Kenseikan or something?" [3]

Asuna nonchalantly shrugged as they both looked over at the girls who fawned over Byakuya.

"Kuchiki-sama!"

"Oh my god he's so handsome!"

"It's really him, I'm soooo lucky!"

"I'm going to get to the advanced class homeroom, just so I can be with him!"

The boys on the other hand, especially those of non-nobility scowled at the Kuchiki. Commoners and nobles nearly never mixed, and this, this was no exception.

"Let's just hope this isn't like Raios and Humbert…"

The examining officer stuttered as he handed the ticket to Byakuya. "Kuchiki-sama… You… You are examinee #112. Please write down your soul age, nam-."

"It's already done, examiner-san."

The examiner bowed as he smiled: "Thank you… Kuchiki-sama."

Byakuya gave a curt nod, fitting of those of nobility, as he gracefully walked towards the chairs.

As time slowly went by, the line in front of Kazuto and Asuna shortened slowly, until it reached them.

The examiner shot them a bored look as he saw their outfits, as he mumbled. "More commoners…"

Kazuto grimaced in the face of his lack of enthusiasm. Here was even more worse than the underworld. Nobles were even more corrupt. To think the 'heaven' of the afterlife was this bad.

"State your name and Soul age. If you don't know your Soul age, step on that machinery." [4]

He gestured to something similar to a weight measurer, as he then looked at Kazuto, who moved towards the machine.

"Kazuto Kirigaya…"

Kazuto then read out the number on the machine: "24 years old, 1 year Soul Age."

Asuna then moved forward, doing the same as Kazuto, as she said: "Asuna Yuuki, 23 years old, 1 year Soul Age."

The examining officer looked at his notepad, checking for names. "Wait a second… You both aren't registered under applicants for the exam. You didn't even pass the first stage yet!"

Kazuto growled as he said to the officer: "That Captain Kensei Muragama dude told us to come, he told us to do this…"

The examining officer chuckled as he lifted his hell butterfly. "We'll see about that lie, kid."

As the line between the officer and the 9th division connected, the comms officer for the 9th division, 5th seat Shinzo Nagama connected, he gruffly greeted the academy staff. "This is the 9th division barracks, what do you want?"

The officer replied quickly, not wanting to waste time. "Could I please ask for Captain Muragama?"

Shinzo growled loudly from the side of his hell butterfly as he scolded the staff: "Captain Muragama is currently doing PAPERWORK! He doesn't have time to 'pick' students into our proud division!"

The officer waited for Shinzo to finish, as he timidly said: "It's about examinees… Kazuto Kirigaya and Asuna Yuuki I believe."

As soon as Shinzo heard those words, he replied much calmer, remembering the story their Captain had told them.

They may very well be our future 3rd and 4th seats. With their reiatsu… Give them a year and they'll be at Lieutenant…

"I understand, I'll get you the Captain right away."

Within a second, the Kensei was on the line, as he asked the officer with a booming voice: "What is it, officer?"

"It's about two examinees…"

Kensei opened his eyes, as he grinned, albeit no one else could see it but Mashiro, who was gleaming from the conversation.

"You didn't treat them badly did you?"

The examining officer frowned slightly as he stuttered: "No no! You know the Head Captain's orders, we have to treat everyone fair!"

Kensei said with all too sweet tone for his reputation. "I trust you're treating them well then? They could very well be our next generation of prodigies."

The examining officer gulped and replied: "Yes sir! I understand. If you excuse me now!"

Kazuto and Asuna looked at him, as Kazuto just letted out a small chuckle at the expense of the officer. Asuna suppressed her giggle, only thanks to her 'nobility' training from her mother. She was a Yuuki after all, it was pretty close to nobility.

The officer groaned as he clenched his fists: "Go."

Kazuto and Asuna both smiled as they bowed: "Thank you, sir."

Assembly Hall for Exams

A man spoke on the stage, as hundreds if not thousands of examinees sat down as they listened to him.

"Hello there, to all you new students, you may know me, as Sousuke Aizen. I am the headmaster of this academy and Lieutenant of the 5th Division. The 5th Division currently manages the academy, hence I shall be overseeing you all."

The girls gleamed at the young headmaster's clean, elegant and perfect demeanour.

Aizen took a look into the audience as he paused, attempting to find the prodigies. Whilst they were prodigies, and powerful ones at that, perhaps surpassing Kaien Shiba, what he needed were personalities easily shaped to his will.

One look to prodigies, known as Kazuto Kirigaya and Asuna Yuuki, and Aizen saw their personalities.

Truly not easy ones to tame. Sad. I believe I'll simply use Kyoka Suigetsu then, that'll eliminate any issue they bring.

"I hope that all students here will pass this exam and enter, however yearly we only have two hundred or so passes. And of those two hundred, twenty are in the advanced class."

He paused for the dramatic effect from the students, as mutters about the passing rate begin from inside the crowd.

"Oh my god… That's like 20% or so from the students here!"

"That's such a low passing rate!"

"How are we supposed to pass?!"

"I hope, that those of you that don't pass, will retry and pass. Those that do, reach my level, or beyond. Everyone should aim for Captain."

He paused again as he took out Kyoka Suigetsu, allowing the students to gleam at it.

"That's a lieutenant's Zanpakuto, is he about to show us his release?"

"So cool!"

"Oh my god!"

Aizen smiled gently and warmly, as he released his Zanpakuto: "Shatter…"

As he was about to, a voice inside both Kazuto and Asuna's mind appeared.

Ah shit, I forgot to write this in prior chapters. I'm the person who summoned you here, just don't look at that Zanpakuto. Plot armour kthxsbye.

Kazuto and Asuna both shrugged at the voice from within their heads as they both simply closed their eyes and took relaxed for a while, not bothering to look at the light show Aizen had made.

Might as well just not look, maybe it's some kinda trap anyway. No benefits to looking - They both thoughht.

Aizen looked all around, as a second before his Zanpakuto was released, he saw Kazuto and Asuna both look.

"Kyoka Suigetsu."

Success.

He smiled as he put on his tricks, a water mist surrounding him, as he explained his Zanpakuto's abilities.

"This is my Zanpakuto, Kyoka Suigetsu. It's ability is to use the moisture in the air to confuse opponents."

"So cool!"

"So graceful!"

"So awesome!"

Aizen smiled as he managed to easily trick once again another batch of Shinigami. Such dumb creatures they were, in-comprehensive of the truth.

He then began announcing the schedule, the original thing he was actually meant to do. "Please settle down now."

He paused yet again for attention, as he confidently said to the students: "Now, about the exam. This won't be like the first qualifier, where you're simply asked to show if you have Reiatsu or not. There'll be several tests."

At the back, a projector lit up as it projected what Aizen was saying. "Courtesy of the 12th. Now, if you listen here, here are the tests."

The first showed an obstacle running course, full of traps. Whilst it was a straight route, you might as well call it a Death Run [5]. Twenty participants at a time, points will be based off your final times. This exam reflects the Shinigami skill of, Hoho."

As Aizen paused yet again to let the students digest this, he continued yet again within several seconds.

He pointed at the screen and the picture as he explained the picture, which was now a picture of a Shinigami firing Kido.

"Since you all don't know Kido spells, Spirit balls will be provided to allow us to see how much power do you have. However, this isn't just how much power you have, this is also how well you can control it. Further instructions will be given by the examiner."

Pausing yet again, to allow digestion, he coughed as he spoke about the final test. As the screen now showed two people using swords to fight, he explained.

"The final exam is for you and the other examinees, to fight a mock battle…"

He paused, as he then concluded his information to give out: "In this mock battle, we will use the same swords the academy uses. Real swords, not wooden swords… So those of you who want to withdraw, do so. This is dangerous… And if you aren't careful, you'll die."

Most students gasped, as Aizen smiled gently: "Best of luck to you all in these tests."

He paused yet again as concluded his talk, as he prepared to leave the stage. "It is my hope, that you all will be able to do this one day. Reach for the highest, be your strongest."

Roars of applaud was heard, as students clapped for Aizen whilst he left the stage.

Several minutes later

In the waiting room, the pressure was tense, as the preparations for the races in the obstacle course went by, Kazuto Kirigaya and Asuna Yuuki both waited for their names to be called.

"Obstacle Course H, No. 20, Kazuto Kirigaya."

Kazuto stood up, as he then heard the next announcement.

"Obstacle Course I, No. 1, Asuna Yuuki."

Asuna stood up as well, as she smiled at Kazuto. "I'm kind of glad we don't have to face each other."

Kazuto nodded: "Me too. But in any case, good luck."

She giggled, as she replied: "But really, if we're more powerful than 9th seats, then wouldn't this be a breeze?"

Kazuto chuckled, as he replied: "You're becoming more like me, not sure if that's a good or bad thing."

Asuna frowned slightly as she hit him softly: "Mou… Kirito-kun…"

Kazuto laughed as he waved. "I'll see you in the finish line, promise me you'll do your best, alright? And I'll do mine too…"

Asuna smiled as she gave him a reply: "Hai."

The two waved goodbye at each other as they parted ways for their separate obstacle courses, losing view of each other as a flood of other spiritually aware souls crossed through between them.

A/N:

[1]: Yeah, I figured I kinda fucked up. Had to use some hand of god here and there. Couldn't have a ninth seat defeat them this easily when their power were up to 3rd - 5th seat, could I? The difference between 5th and ninth are huge. And for my reference, I call for Aizen.

The entire squad, can't even defeat the lieutenant and only perhaps the 3rd to fifth seated officers' strengths together could probably down one. Then, you have the Captains, the pinnacle of strength of the Gotei 13. A Captain is ten times stronger than a lieutenant, thanks to their Bankai.

[2]: Gabriel and PoH (Leader of the guild known as LC) both appear in the Light Novels of SAO, 15+. Aka part 2 of S3. Since this story takes place after season 3, with the reasoning of Kazuto and Asuna's abilities revolving around their underworld persona and for Kazuto, his own sword releases, I suggest you read the LNs, because there will be spoilers for S3 p2 here and there.

[3]: I honestly don't know how to spell it, which is why this technically breaks the 4th wall lol.

[4]: Just for future usage so we and the cast know how young our characters are. Soul age means how long you've been in Soul Society. And to not complicate things, they've been here for a year. I don't bother with the time-scale that much, please don't oof me.

[5]: Nostalgia about that one Roblox game I played when I was 9.
