Three particles...
It might seem insignificant to Lucifer, but this small amount of "The Fire of the Will" was enough to make anyone a threat to the world.
Allen knew that he could not defeat Zero using only his own magic power, so he began to use the "Dunamis Demiurgos" as a second source of his magic power. This would not increase his strength, but it would give him an inexhaustible source of magic.
*BOOOM!*
Both fists collided, stealing everyone's breath. An explosive impact released massive amounts of magical power.
"Oh, you're strong..." Zero smiled.
Allen sneered with contempt, "Yeah, but you're pretty mediocre..."
The mockery made Zero furious. He unleashed even more magical power through dark energy and struck. Allen didn't fall behind, boosting his speed and endurance x100, and began exchanging blows with Zero.
The sky filled with resounding impacts that made the heavens tremble. Most of those present couldn't even see the fight, except for the Chat and the girls watching through the system. As always, the system was considerate of spectators—many of whom were ordinary people—so it adapted the speed to allow them to follow.
Allen's fist sank into Zero's stomach, knocking the wind out of him. Immediately, Zero smirked and countered with a punch to Allen's cheek. However, Allen managed to defend with a small barrier that was shattered but absorbed much of the force.
"See? I told you you're mediocre..." Allen said coldly.
Zero widened his eyes, only for a punch to smash into his face, followed by a kick that sent him flying like a meteorite. Upon crashing, he created a massive explosion that raised a cloud of dust.
"Dark Pulse!"
"...!"
Out of the dust, a blast of dark energy shot toward Allen, tearing through the atmosphere like a ray of death.
Allen didn't take lightly an attack with the power of three particles. "Space God Slayer Magic: Divide!"
The space in front of Allen solidified like a transparent barrier. The attack crashed into it, causing a massive explosion of Dark Magic
"Allen!"
"Allen-san!"
The girls panicked at the sight, while Sorano watched in silence, though she bit her lip slightly.
Allen emerged from the explosion with a few burns on his clothes but no wounds.
"Die!"
Zero appeared above Allen and struck with a Dark Magic orb. Allen's head shattered, and Zero grinned in delight.
But before anyone could grieve, Zero's expression turned to shock. He froze when he saw that what poured out of Allen wasn't blood—but rocks.
"Huh?!"
"Looking for someone?"
Allen appeared at Zero's side with a clenched fist. He had created a rock clone and imbued it with "Alive" and "Life God Magic" so he was able to trick Zero.
"You!"
Without the slightest mercy, Allen struck Zero's jaw. "One-Man Army x150 Strength!"
Zero's jaw broke, his brain rattled from the titanic force, and he was sent flying so fast he broke the sound barrier multiple times.
"Space God Slayer Magic: Astral Rift!"
Allen vanished and reappeared in front of Zero, even faster than with "Apparition" or One-Man Army Speed x100.
Zero's eyes narrowed as he caught sight of Allen's fist. It began to suck in the atmosphere itself, warping the surrounding space.
'By using Master-level Wind Magic combined with "Wind God Magic," Allen had compressed the atmosphere into his fist so tightly it turned into a transparent white sphere.'
"You Bastard!" Zero surrounded himself with a dark barrier.
With cold eyes, Allen declared his sentence: "God Wind Magic: Aerion – Ten Thousand Tons!"
Allen's fist shattered Zero's barrier, then slammed into him, creating a shockwave so powerful it swept across a hundred miles, with a thunderclap heard even farther away.
Zero couldn't think; he just felt his organs explode and his bones break. It was too strong and too sudden a blow.
Zero crashed into the ground, shaking the entire region. Fairy Tail's mages clung to anything they could to keep from falling.
Soon, everything stilled. Lucy, Erza, Wendy, Carla, Sorano, and The Chat stared in disbelief at the screen. Where the Nirvana ruins once stood, now lay a crater spanning several miles.
The Nirvana magic was never activated. Zero fell into the depths of the abyss while Allen held three red sparks in his hands.
"Told you—you're mediocre..."
Allen had faced several particle bearers and realized not all could extract the same amount of power. Take Jose, for example—he practically killed himself because he couldn't control it. Then Jellal, who despite having two particles wasn't nearly as terrifying as Deliora.
And finally, Zero—who had three particles, but was only slightly stronger than Deliora, who with just one particle had overwhelmed Allen back then. Of course, that only highlighted how much stronger Allen had become since those days.
Allen held the particles in his hands, then looked toward the abyss.
Was it a short battle? That was the point. The longer it dragged out, the greater the chance his opponent would pull a power-up out of nowhere. Allen wasn't Goku or Vegeta; he wasn't going to let his enemy get stronger. From the start, he went all out.
Last words?
Who cares what a lunatic bent on destroying the world has to say?
Allen had a clear goal, and he acted accordingly.
"Haa..." Allen panted, feeling pain throughout his body. Using One-Man Army above x100 damaged him, damage that even a current red potion couldn't easily heal.
....
Allen returned to the crater's edge where the others waited. As he landed, Lucy threw herself at him like a meteorite. Erza tried to look strong, but when she saw Allen's visible exhaustion, she did the same.
Wendy smiled through tears, Carla reassessed Allen, accepting that he wasn't just a pervert. As for Sorano, she was in shock—she never expected Brain, no, she never expected Zero to be defeated despite wielding power beyond imagination.
After regrouping and capturing all the enemy mages to hand over to the Rune Knights—except for Angel, who had another fate.
The team decided to return to the Cait Shelter.
Once back on the Colossus's head (Allen had to rebuild it since the last one was destroyed), the atmosphere relaxed.
Natsu and Gray guarded the prisoners, most of whom were unconscious—except for Hoteye, who wouldn't stop clinging to an uncomfortable Gajeel, and Sorano, who stayed closest to Allen. He didn't see the need to use sealing magic on her to block her power; after all, Sorano was a former member of Oración Seis who sought death. She had already surrendered and offered no resistance.
As for Aries, Scorpio, and Gemini—the last of which Sorano hadn't used due to circumstances—they were entrusted to Lucy. Allen didn't need to break the contracts; Sorano dissolved them herself, with one condition: that Allen find her younger sister Yukino, her only remaining bond to this world.
Erza and Lucy gave Sorano compassionate looks. Even if she had been their enemy and done terrible things, they couldn't help but feel pity for the past she endured—and Erza even felt indirect guilt.
....
– Chat –
Thor – I honestly expected more of a fight from that Zero guy...
McDragon – Yeah, he looked like he had what it takes, but turned out to be a fraud.
Gwen – Don't be ridiculous. Allen couldn't afford to drag it out. Did you forget what happened with Deliora?!
Jalter – Exactly, and it's not like that bastard was weak—Allen's just too strong!
Kurumi – Ara Ara, I didn't expect Jeanne-chan of all people to be the first to defend him~
Jalter – Shut up, it's none of your business! And why do you always butt in when I comment?!
Kurumi – Kihihi, because it's fun to tease you~
Jalter – $#&¢$...
"Don't tease her too much, Kurumi..."
Kurumi – Yes, Master~
....
Allen chuckled at the comments, then turned his attention to Sorano. Since he had no reason to refuse, he accepted the deal.
[Main Mission: Nirvana – (Completed) Rewards +10,000,000 J + Lightning Magic + Lost Magic: Dark Magic + Inversion Magic "Tenkai"]
[Optional Mission: Cait Shelter – Go to this mysterious guild. All the answers will be there (Completed) + Forging Magic + Knowledge of Roubaul "Roubaul, a legendary artifact creator with over five hundred years of experience, designer of Nirvana. His knowledge is invaluable"]
Allen's eyes widened. Receiving Brain's Lost Magic and the "Tenkai" was already a huge surprise, but gaining Roubaul's knowledge was completely unexpected. With it, his artifacts should stop being mediocre—or rather, it was always the fault of the poor-quality materials.
Allen smiled, satisfied with this great harvest.
....
But...
Not everything can end happily. Upon returning to Cait Shelter, Wendy had to face reality. Roubaul had been holding his illusion magic far beyond its limit, and thus had to reveal the truth to Wendy and Carla.
The old man bid them farewell with a smile, along with the rest of the small guild, while asking Allen to look after Wendy.
"Don't worry, I'll take responsibility for protecting every member of Fairy Tail..."
His words, filled with seriousness and a heartfelt promise, surprised everyone who had grown used to the bastard troll who frightened them with strange brews. But as everyone knew, Allen was serious when he needed to be.
With that, the man vanished, along with Cait Shelter's emblem from Wendy and Carla.
The girls comforted Wendy for a while until she calmed down. Even with her heart heavy, she approached Allen with determination.
"I want to join Fairy Tail, Brother... no, Master!"
Allen smiled upon seeing Wendy's firm gaze, despite her tears.
"Wendy Marvell, you've shown me your courage, your heart, and your kindness. Of course, you're more than welcome... You too, Carla."
The two hugged each other while smiling. Soon Lucy joined in, and the rest looked with a smile.
Sorano observed with a tinge of jealousy. Maybe, just as Allen had said, she thought the world was rotten only because she had seen its ugliest side, without knowing people like Allen.
"Hey..."
Out of nowhere, Cobra, who had already woken up, interrupted the welcome.
"Cobra?" Natsu reacted with hostility.
Cobra looked at Allen with pleading eyes. "I have no intention of begging for my life or anything like that. I only ask you not to give Cubellios to the Rune Knights."
"Wait, Erik, I'll go with you. We're partners!" said a female voice, shocking everyone when Cubellios spoke.
"Stop, Cubellios. Most likely you'll be sacrificed. It's better if you stay..." Erik said with resignation.
Allen looked at the talking serpent. Her loyalty was clear, but the fact that she was intelligent and loyal didn't erase her crimes.
"I beg you. Everything Cubellios did was because I ordered her to. Her only crime was obeying me!"
Even Natsu, who fought Cobra, couldn't help but feel compassion at the sight of him throwing away his pride to beg for his partner's life.
"Allen..." Erza approached him and took his hand. "They were also in the Tower of Heaven..."
The pain caused by that tower extended far beyond imagination.
Allen sighed. "I get it... all these sad moments are wearing me out. Fine..."
"Thank you!" Cobra smiled in relief.
"Master," Gajeel hesitated to speak, but seeing the situation, he went ahead. "Richard's brother is also missing. Is there any way to find him?"
Hoteye—whose real name was Richard—opened his eyes wide at Gajeel. Richard didn't beg, since he had already decided to pay for his crimes. However, he had one regret: never finding his younger brother.
"Younger brother?" Allen blinked at Hoteye. Knowing he too had been a slave in the Tower of Heaven, one of Allen's eyebrows twitched. "Don't tell me his name is Wally?"
"How do you know?!" Richard exclaimed.
Allen looked at him and remembered Wally. "Instinct?"
"Wait—you're Wally's brother?!" Erza exclaimed.
[Host, the world is small, isn't it...]
'Seems so...'
That day, the news spread across the continent: Oración Seis had been eliminated, all its members captured—except Brain, presumed dead, and Angel, whose whereabouts were unknown.
The world returned to normal, while the fame of the youngest guild master in history, Allen Walker, spread like legend.
....
(Somewhere)
Acnologia—that name brought disaster. That name brought fear and despair. A dragon slayer who became the strongest, the reason for their near extinction.
This man stood before someone sitting on his own throne at that moment. But far from being angry, he looked... scared.
Acnologia, even as the ultimate monster and the strongest being in the world, couldn't stop a bead of sweat from rolling down his cheek.
"Oh, you're back? Did you get any?" said a man with a kind yet proud smile. He wore a white suit, had golden hair, and an unusual appearance for this world.
"Yes... I didn't destroy anything..." Acnologia admitted, unable to hide the suffocating feeling. He, who should be the absolute being of this world, could only bow his head in obedience.
The man's clear eyes looked at Acnologia with approval.
"Good. Don't worry, your time will come..."
The man stood, ready to leave, since he shouldn't linger in that world. Just as he passed Acnologia, the dragon slayer spoke in a low, hesitant voice.
"If I succeed... if I kill Allen Walker... will I gain the power to destroy the world?"
The man smiled. "Yes. Destroying this world will be possible... but all in due time."
Destroy the world? Destroy the universe? Destroy the multiverse? Such things were trivial for this omnipotent being.
The man vanished. As he did, Acnologia fell to his knees, as if all his absolute strength had only been enough to keep him from fully collapsing in his presence.
"I don't care what he is. To fulfill my dream of exterminating all dragons in this world, I'll do whatever it takes!" Acnologia sat back on his throne, trying to regain some dignity.
Then he opened his hand, where ten crimson sparks floated.
"Once he gives the order... I'll burn the world to destroy you, Allen Walker..."
.....
(Days later)
Allen woke up in his bed with Juvia clinging tightly to him, unwilling to let go. Since she hadn't been chosen for the Oración Seis mission, she had felt very sad, and Allen had to comfort her. That was easily solved by letting her sleep with him for a week.
[Special Notice: The necessary conditions have been fulfilled. The host may now leave the world of Fairy Tail.]
"What?!" Allen shot up, causing Juvia to fall off the bed.
"Ah!"
"Sorry, Juvia!" Allen apologized, but he was in such a good mood that he kissed her, making her melt in his arms.
Allen savored her beauty, knowing that at last, he could leave this world.
"A-Allen-shama❤️~"
