The war just ended like that

Acnologia, a human who vowed to exterminate all dragons, even willing to transform into the very creature he despised the most, just to fulfill his determination and oath.

As humans and dragons waged war, Acnologia, who had just fully transformed into a dragon, decided to intervene.

For him, this war was the best opportunity to kill as many dragons as possible.

Coincidentally, he even encountered Belserion, known as the sage dragon.

After a fierce battle, Acnologia managed to kill and even devour Belserion.

However, before he could celebrate his victory, Acnologia suddenly felt something he loathed deeply.

Fear, an overwhelming fear, the kind of fear he experienced when facing helplessness.

Acnologia, who had now become a dragon, hated the fact that he was feeling fear again, just like when he was a weak, powerless human.

He searched for the source of this unsettling feeling, and eventually found it in the form of a human who could magically fly or perhaps hover in the air, as if proclaiming himself the true ruler of the skies.

Acnologia, having found his target, prepared to attack, but suddenly, he felt something strange.

He looked at one of his hands—or what should have been his hand—only to find it missing, with blood flowing profusely from the spot.

Pain started spreading, sending information to Acnologia's brain.

'Damn!!! This hurts so much, how is this possible?'

Acnologia roared in pain, but in his mind, he was fiercely trying to figure out how a mere human could wound his body with just one move.

Without hesitation, Acnologia intended to retaliate by releasing his breath attack. He was certain that the figure before him would be obliterated by this attack, as his breath was capable of killing or at least mortally wounding other dragons.

But when he saw that the figure was merely standing there calmly, then making a strange movement to create a weapon that looked incredibly weak, Acnologia hastened his attack preparation. However, when the weapon had fully formed, his instincts as a beast screamed for him to flee as far as possible.

Fortunately, this time Acnologia managed to survive because, just before the spear-like weapon hit him, two strange figures with auras far more terrifying than the enemy before him appeared.

"Please can you let this creature live a little longer, Kaoru-kun?"

One of the two figures, whose entire body was covered in black smoke, spoke to the enemy, apparently named Kaoru.

"Sorry, Kaoru-kun, but the wheels of fate still say this creature must live a little longer, so we can't allow you to kill it."

And the second figure, whose body was enveloped in golden flames with tattoos forming some kind of symbol or pattern, spoke about fate or something Acnologia had no knowledge of.

But one thing was certain: if he could devour all three beings before him, he would undoubtedly become even stronger.

Fortunately, even though two of the three figures knew what was on Acnologia's mind, they never considered him a threat, as no matter what he did, Acnologia would be like an ant before them.

Their purpose in appearing in the mortal world was only to stop Kaoru from killing Acnologia earlier than fate had ordained.

-----

Kaoru was slightly annoyed because one of his few friends had been killed and eaten just like that.

If Belserion had simply died and fallen on the battlefield, Kaoru would have been only sad, but Acnologia insulted Belserion by turning him into food.

That was why Kaoru intentionally ignored Cronos' advice back then, not to intervene directly in the war between humans and dragons.

After obliterating one of Acnologia's hands, this time Kaoru compressed the space around him and created something resembling sheets of cloth, then with perfect control, he wove the cloth into a weapon similar to a spear.

The same technique used by Sirin in her Herrscher of the Void form.

When he saw how easily Sirin did it, Kaoru thought that the technique was nothing special.

But after doing it with his own hands, Kaoru realized just how terrifying Sirin's computational ability was in the realms of space, time, and dimension.

Fortunately, Kaoru's body had already transformed into a Herrscher's body, and he also had 'The End,' which greatly helped him analyze and practice various types of techniques and abilities.

If Kaoru's body hadn't transformed, he was certain that his brain would have turned to mush just by trying to compress space as he had just done.

After creating the weapon, Kaoru, who intended to obliterate Acnologia, was suddenly stopped by Ankhseram and Cronos.

Growing even more annoyed, Kaoru tried to control his emotions and listen to the reasons why these two gods were interfering.

And as Kaoru had suspected, Acnologia was indeed fated to die, but now was not the time.

The two gods also informed him that they wouldn't fight Kaoru even if he forced the issue, but it would be different with 'Fate,' which would certainly impose severe punishment on Kaoru if his decision was to eliminate Acnologia.

Despite being angry, Kaoru still had common sense; he also understood how powerful abstract entities could be since their power was simply to control anything related to the concepts they represented.

"Tch... whatever!"

Kaoru, realizing that now was not the time, decided to retreat.

The two gods also seemed pleased because Kaoru agreeing to follow the flow of 'fate' meant that their world wouldn't end in a miserable state.

However, there was one being who wasn't pleased with all this.

"Gruaaa!!!... where do you think you're going, attacking and then just leaving like that!!!"

Though his words were a bit garbled due to his transformation, the meaning was still clear enough for people to understand.

Kaoru, who had already turned to leave, suddenly stopped for a moment and glared sharply at Acnologia.

"Herrscher of the Void Kaoru, remember that name, the name of the one who will obliterate your entire existence, Acnologia!"

Kaoru then opened a dimensional portal and left the battlefield, followed by the two gods who also decided to return to their realms.

And Acnologia, feeling ignored and belittled, grew even angrier, but he wasn't foolish; if he continued to rampage, there was no guarantee that the three beings wouldn't intervene.

And maybe they would disregard everything and decide to obliterate him right then and there.

Knowing that he was still weak, Acnologia decided to leave and continue exterminating other dragons to become even stronger.

-----

Kaoru arrived on the veranda of a castle, exhaling deeply.

"Sigh...."

"So, Belserion truly fell?"

Kaoru was startled by the voice of a woman he knew very well.

Under normal circumstances, Kaoru would never have missed the presence of this woman, but due to the loss of one of his close friends, Kaoru was slightly off guard.

He then looked at the woman.

Her long red hair blown by the wind made her look even more beautiful than usual, but the tears that wet her eyes seemed to disturb and ruin that beauty.

And Kaoru knew the reason for those tears.

He approached the woman and wiped away her falling tears.

"I'm sorry, Irene. Belserion's fate was to fall in this war, I know this is sound cruel but we, as weak mortals, are powerless to fight against a predetermined fate."

Kaoru could do nothing but comfort and calm Irene, even though he knew she was deeply saddened and angry.

But perhaps due to his presence, Irene didn't act rashly and wasn't blinded by revenge.

Kaoru's role this time was to ensure that Irene didn't pursue Acnologia and end up dead, and Kaoru was willing to do anything for that, even if he had to become a scumbag taking advantage of someone's misery.

Because after spending some time with Belserion and Irene, Kaoru had developed special feelings for them, and he considered them more than just passing acquaintances in his life.

----

Several years passed, and now in a meeting room, three people were discussing the future.

The first person was, of course, Kaoru, and thanks to his body, which had evolved into a Herrscher's body, the power of time seemed to have no effect on him.

Beside Kaoru was the queen of the Dragnoff kingdom, Irene Makoto Belserion.

That's right, Irene had officially married Kaoru, taking on his surname and the name of their friend, Belserion, to honor his memory.

In just a few years, Irene had grown from a young girl into a very captivating woman, whose beauty was beyond the description of even the kingdom's most beautiful woman.

And before them was a friend Kaoru had found while wandering in search of the young Dragon Slayers.

A young man with short black hair, wearing a robe-like outfit dominated by black, a youth known as the Black Wizard.

Zeref Dragneel, the main antagonist of the Fairy Tail series, and the elder brother of the main protagonist, Natsu Dragneel.

"Hmmm.. the Time Stagnation Magic is actually quite easy, but the ether consumption makes this magic very dangerous. Are you sure you want to use this magic for that girl?"

Zeref knew why his two friends were asking to be taught time magic, but he was still curious why they didn't just send their daughter with Natsu and the others if those children were to be in an era 400 years into the future.

"It's fine. At the very least, I want to ensure our daughter is the oldest among those children."

When Kaoru gave that simple reason, Irene just chuckled, knowing her husband only wanted that.

Because if they sent their daughter with Natsu, that meant their daughter would be the youngest in that era, and Kaoru didn't want his daughter to be bullied by those naughty kids if she is the youngest.

Zeref, who knew that he couldn't win an argument against Kaoru, simply sighed and continued the magic lesson.

Of course, Irene was the one learning because Kaoru just need to see it once to understand it.

'Why does it feel like I'm dealing with children..'

Zeref grumbled inwardly.

Yes, he might have lived longer than Irene and Kaoru, but his mindset wasn't very mature, and when dealing with the two of them, Zeref felt like a child who had to hold back his temper.

Of course, Kaoru and Irene were aware of this and intentionally liked to tease Zeref by showing him affection and sometime playing pranks on him, which always made Zeref even more frustrated.

After they learned and applied the magic, several days later, Cronos comeback to send Kaoru back to the future.
