a/n: yall this took me tf out T-T
i hope i managed to portray the manga fight scenes properly because writing what's meant to be read in pictures is confusing sometimes - specially if writing quick-paced fights from a manga because sometimes you can't distinguish what's going on where T-T
CHAPTER 02: A Thousand Thunderbolts
He launched onto the battlefield, leaving no time to mourn my dad's death.
I was still kneeling, dizzy and shaking, thoughts a jumble of rage, sadness, and this gutting helplessness I couldnât swallow down. My eyes refused to moveâlocked on Dadâs corpse. Split in half. Blood painting everything in a grotesque, suffocating crimson.
I didn't know anyone here - save for Shoko, Yuta and Maki.
Sukunaâs eyes met mine across the field. That same cruel, mocking smirk curled at his lipsâlike he knew exactly what heâd done. Like he enjoyed it.
My chest clenched. Burning. So much burning.
My lungs shrank. My throat closed.
Air. I need air.
ineedairineedairineedairâ
A raw gasp tore out of my throat, hand flying to my neck as I choked it down. My eyes blurred with tears.
But the world didnât stop spinning.
Kashimo was still in the air.
And the skyâ
The sky was falling.
Despite vaulting 203 meters off the ground, a heaping chunk of ice towered above him. I managed to catch the two figures that stood atop it: a girl in a pale kimono, white hair fluttering like frost; and beside her, a blond man in black, face steeled with focus.
Assuming white hair's clothes and stance, she was the one in control of the ice.
The black guyâas much as I could seeâ pulled a Domain Expansion, engulfing himself and the white-hair in the black sphere. Nevertheless, the ice block continued plummeting towards the Earth.
I was never so awe-struck and scared shitless at the same time in my life.
Sukuna snapped his fingers.
The massive chunk of ice fractured mid-air with a deafening crack, fissures webbing across its surface like lightning veins before it erupted into a thousand jagged shards, each one glittering like glass in the dying light. The frozen debris fell down in a deadly cascade, slicing through the air as if the sky itself were falling apart.
Like judgment. Like death.
Yutaâs arm slammed around me, yanking me up and shielding my head with one hand.
âYouâre either severely suicidal or just incredibly stupid,â he muttered, frowning.
I blinked up at him. His voice was shaking too.
âWhy not both?â I whispered, too low to be heard.
At that moment, the only thing I wanted more than dying was to see Megumi.
Yuta smacked me lightly upside the head and carried me to the others.
I barely noticed the sudden attention. I kept close to him, trying not to flinch under the weight of their eyesâDadâs students, his comrades. The ones who knew him.
Yuta wrapped an arm around me. I leaned in, focusing back onto the wreckage haunting the battlefield in front of us.
Clutched casually in Sukunaâs right handâlike it meant nothingâwas a weapon. Sleek, black, with a brutal, elegant curve to it.
That was Yorozuâs cursed tool. Left behind as a product of her binding vowâher final, desperate act before she died. I remembered reading about it, tucked in some banned scrolls in Shokoâs study. A cursed tool forged from pure intention. Something that shouldnât exist unless someone willingly gave up their life for it.
And Sukuna had it. Like it was nothing.
A cursed tool infused with the will to kill Sukuna.
Its cursed effect was supposed to manipulate electromagnetic force, amplifying electrical damage beyond what most could survive. Kamutoke shouldâve been deadly. Butâ
My eyes flicked to Kashimo. Still standing. Still unfazed.
His cursed energy was fundamentally resistant to electricity. That was the one innate trait that could cancel out Kamutokeâs effect.
Sukuna knew. He wasnât just fighting. He was taunting. Playing.
Even now, with a cursed tool born from love and madness and death in his hand, he was just warming up.
Kashimo's voice rolled over the battlefield like thunderâquiet, but impossible to ignore. The kind of voice that made your instincts brace for impact before your brain even caught up. "Sukuna."
"Did you earn the title of The Strongest? Or were you simply born as such?"
Sukuna's voice scraped down my spine like a curse made fleshâvelvet over iron, calm and terrifying. Like someone who knew the world would kneel, eventually. "Who knows? I was born an unwanted, cursed little wrench. That much I can say."
"How can you connect with others? How can you love those beneath you, all while not knowing of weakness? That's something I never understood. I was always surrounded by those as feeble as the dirt beneath my feet." The moment he spoke, something in my body went still. Like even my blood was waiting to hear what heâd say.
It wasnât loud. It wasnât angry.
Like the universe paused just long enough for a god to speak.
"So, enlighten me. Is strength solitude? Or is the endless search for greater power simply a cross the strong must bear alone?"
Sukuna's voice was calmâtoo calm. Like a lion bored with the idea of eating yet another sheep. He chuckled, scratching the site of his head. "My, my. How greedy. You ask for so much. Sure, I'll teach you. Give me your best, revenant."
Kashimo flashed a grin as bright as his lightning, launching for Sukuna at sublime speed and rising his sword with grace only the gods have. Sukuna dodged without breaking a sweat, swiftly turning to the side.
The air around Kashimo rippled, humming with electricity so thick it felt like static crawling beneath my skin. His body shimmeredâno, transformedâbecoming something more. Like every nerve ending was a lightning rod, every muscle a conductor for the storm he wielded. My eyes widened.
Cursed technique Release. Mystic Beast: Amber.
It wasnât just a technique. It was a total metamorphosisâturning him into a walking arsenal, every twitch and flex a potential weapon forged from raw electricity.
I could almost see the electric potential pulsing just beneath his skin, a glowing tide of energy ready to snap and crackle into violence.
Every step he took sparked the ground beneath him, every breath charged the air around us.
Facing Kashimo wasnât just fighting a sorcerer.
It was facing a storm with teeth.
Sukuna was taken off guard as a barrage of non-stop, heavy fists collided with his face, sickening cracks echoing throughout the wreckage and chaos that was the battlefield and reverberating off the crushed buildings and debris.
I swallowed hard, watching Kashimo move like a storm made flesh.
Mystic Beast wasnât just power. It was total commandâelectricity shaped by his body, bending every spark and bolt into a weapon.
It was so... raw. Brutal in its simplicity.
Dadâs Limitless cursed technique was elegantâcontrol over infinity itself, a dance between space and time, a flawless barrier and blade.
Kashimoâs release, on the other hand? It was a raging tempest. No finesse, no fancy tricks. Just pure, unrelenting force.
There was a terrifying clarity to it. He doesnât hold it back, I thought. Not even a sliver of it. The moment Kashimo released his cursed technique, it was like a storm god had been let loose. His body wasnât just a vesselâit was a conductor. Every flicker of lightning, every electric scream of airâit belonged to him.
I understood it more than I wanted to.
His technique turned emotion into violence. Turned body into weapon.
Soulflare Convergenceâmy cursed techniqueâlived under my skin like a second soul, each element tethered to a different part of meâflame for rage, water for grief, earth for fear, wind for... hope? Maybe. I don't know.
The more I felt, the more it answered. The more it answered, the harder it was to stop.
Against techniques like Kashimo's and mine, precision would only get you killed. You either outrun the lightning or become the storm yourself. No other way to survive.
I swear I could see fear flickering in those flagitious eyes of Sukuna's. The ones that didnât look at you. The ones that judged if you were even worth noticing. He dodged an attack, staggering back as he wasâyet againâhumbled by a devastating slam of Kashimo's fist to the temple.
I saw it all at onceâhow his body moved faster than thought, how the air vibrated around him in a frequency only he could hear.
Hajime wasnât just controlling electricity. He was electricity at this point. His cursed technique didnât just make him strongerâit rewrote the rules of being human.
He was accelerating his brainâs synapses, matching soundwaves to the natural frequencies of matter, vaporizing solid ground with a single directed burst of electro-magnetic radiation.
It was beautiful. It was horrifying.
That was the priceâhis body. Once his cursed technique hit its limit, thereâd be nothing left to hold him together. He would just crumble.
That monster hadnât even started yet.
My eyes dropped to the weapon in his handâKamutoke. Yorozuâs final vow. A cursed tool born from obsession.
Heâd been waiting. Holding back. Delaying a transformation I hadnât even realized he was capable of.
Apart from Reverse Cursed Technique... he has another way to restore his body.
One he can only use once.
A method heâd suspended this whole timeâthe final phase of his incarnation.
It wasnât just a fight.
This was ritual. Chess. A countdown.
Sukuna hadnât come to win. Heâd come to become.
He emerged from dust and rubbleâfour arms, two faces. A mouth on his stomach. His full form. The utter doom of jujutsu and humanity as we know it.
I had watched gods rise before. But this?
I knew that power. Iâd felt it, tasted it in the air like the stench of metal and the rot of death. It was ancient. Arrogant. Terribly patient. Like it had been waiting for this momentâfor usâwith fangs tucked behind a smile.
And it wasnât just Sukuna. It was something older, something worse.
He wasnât fighting Kashimo anymore.
He was unveiling himself. The real him.
My cursed energy spiked before I even realized I was scared.
Fire buzzed under my skin. Wind thrashed in my lungs. The earth inside me crackedâsplitâscreaming something primal.
Soulflare Convergence. It reacts to how I feel. Always has.
And I think, in that moment, it thought we were going to die.
Not even the spirit bound to me stirred. Aki knew too. This wasnât just danger.
I suddenly remembered something Dad once said.
âThere are some things in this world that shouldâve never been allowed to exist.â
Heâd been smiling when he said it, joking with Shoko over instant ramen, but Iâd never forgotten the weight in his voice.
This⊠this was one of those things.
And Iâm not ready for it. I can fight. I can bleed. I can kill if I have to.
But Iâm not ready for this.
Iâm not ready to be the one who survives this and tells the world what we saw here.
And thatâs what scares me most.
That for the first time in my life, I want to run.
