Hello everyone! Synxisdemind here to give you a peek into the mind.
My first fic, been reading a lot and decided to work out my own idea and here it is.
Rebirth Academia: Thunder's Saga. Decided after an immense spell of deliberation and finally we've got it. (exhales in relief) Ok…
Generally, Zenitsu reincarnated in the MHA world as Denki's twin. I consider it fitting quirk-wise. Anyway, the rest is just to read.
Starting a little slow for the first few chapters but I guarantee the action pick up soon.
Enjoy!
BIRTH OF THUNDER
(Infinity Fortress ruins)
Standing on the battlefield, his deep yellow eyes flitted across the ground, he could see the bodies of his slain comrades and even the heavily injured forms of the Hashira.
He stumbles into a half kneeling position with his blade as his support. His ears ringing, head throbbing, face and body littered with injuries and caked blood, legs screaming in immense pain from overuse of his techniques, one of them even almost useless yet Zenitsu Agatsuma realized that he cannot let his body fail now. Not in this battle against the greatest enemy of the demon slayers, Kibutsuji Muzan.
His friends, Inosuke and Tanjiro though in similar conditions, are still locked in an intense exchange with the demon lord. Zenitsu feels the urge to let the fatigue set in but he resists. He tries to push himself to stand wanting to help his two friends but he staggers not even able to muster enough strength to do much else.
"Jiji, please give me the strength to help my friends one more time", he mutters under his breath. In that moment, he feels his master' spirit prop him up and a surge of strength flows through him. Setting into his familiar stance ignoring the aching and numbness in his leg, he sucks in air to fill his lungs and exhales through clenched teeth as he calls mentally.
"Thunder Breathing: First Form – Thunderclap and Flash" Tensing his leg muscles, he rushes forward slashing through the Demon Lords tendrils. This enables moment of respite enables Inosuke and Tanjiro to continue their onslaught.
"Sun Breathing: Dance" Tanjiro strikes with an overhead swing.
"Beast Breathing: Fifth Fang - Crazy Cutting" Inosuke slashing at Muzan with ferocity.
"Inosuke keep attacking!" Tanjiro screamed while setting up for his next attack.
"Got ya, Monjirou!" Inosuke yells back as he continues slashing.
"Sun Breathing: Setting Sun Transformation"
He tries to hit another one, "Solar Halo Dragon Head Da-" but he loses his footing stopping his attack in the Demon Lord's tracks.He is about to pay for that mistake with Muzan's tendrils rushing towards him with the intent to impale and rip apart and in that split second.
"Thunder Breathing: First Form - Thunderclap and Flash — Godspeed" Zenitsu moves between them to takes the blow for him allowing Tanjiro to then use,"Sun Breathing: Solar Halo Dragon Head Dance"
"Raging Sun"
and finally,"Sunflower Thrust"in quick succession.
His body drops to the ground limp with blood oozing out of holes from the now retracting tendrils, chest rising and falling slowly, His eyes glassy as they slowly but surely embrace his impending demise. He barely turns his head to see Muzan pinned to the wall by Tanjiro's sword.
"I'm sorry guys. I tried my best but this might be it. I hope you all win for all of us" He sank into his thoughts as he watched his friend fight.
"A world without demons where people can smile at night just as brightly as the day, Tanjiro I know you can do it. The sun's almost out"
"I was always so scared of dying, so timid, felt so weak and worthless but you guys and gramps all showed that I belonged, that I too was capable of great things. I'm glad I got to meet you all"
"Inosuke you jerk, you were always so annoying but you were a great friend"
"Nezuko, I wish I got to see you turn human and tell you how I felt. I wish I could have seen you again, just one last time. Please live well" He mused as a tear runs down his eye.
With that his heart beat slows before coming to an eventual stop. "Goodbye" his last conscious thought.
There lay Zenitsu Agatsuma, a man later honored as one of the great heroes who gave his life for the defeat of the Demon Lord, Muzan alongside the Hashira: Mitsuri, Gyomei and Obanai. Missed dearly by his friends, mourned by all. His sacrifice created the chance for victory by preserving Tanjiro's life. Such was the tale of the thunder demon slayer, Zenitsu Agatsuma. A valiant end worthy of a warrior of his level.
Or so it should have been.
(Saitama Red Cross Hospital)
June 29th
As a former security operative, Goto Kaminari was a brave man, never afraid to take up any challenge but today, faced with a challenge he could not influence in anyway, he found himself pacing back and forth frantically in front of his wife's delivery room. He could hear some murmuring behind the door but majority of the sound was overshadowed by his wife's screams.
The sound of a crying infant echoed through the delivery room. A blond woman lay on a hospital bed with a sheet covering her lower body.
Sweating and screaming, she pushed again and the cries of one became two. The nurse on duty gently cleaned and laid the two babies, one with black hair and the other blonde in their mother's arms.
"Congratulations Kaminari-san, you have two beautiful baby boys". The female doctor said.
"Thank you Kaga-sensei" the mother replied before looking at her sons with a tender smile on her lips.
"I'll let your husband in now" The nurse said before going to inform the man.
Outside, he was still pacing when the door opened, Goto looked up and saw the nurse.
"Sir please, your wife is waiting for you" Wasting no time, he moved to the door.
He was ushered in and burst into happy tears at this sight of his wife and their kids.
"Mio!" He exclaimed, rushing towards her.
He hugged her gently and kissed her forehead.
"I'm so happy sweetheart. Thank you so much" He said with a smile.
"Me too!" replied, looking him with a tired but exhausted smile before returning back to their sons. "They're here"
"Welcome to the family, Yuuma, Denki"
( 4 years later)
The Kaminari family was an average family. Well as average you can get in a world where everybody has superpowers.
Goto Kaminari, a retired security operative, now working as a security consultant for business firms and Mio Kaminari, a retired pro hero "Volta", now a housewife. Met on a certain villain case, fell in love, got married and then twins just like that.
Speaking of the twins, their sons, Yuuma and Denki, both soon to be 5, were their little wonders. Though the twins got along well enough, their differences were quite clear.
Denki, the younger one was ever the rambunctious child. He looked just like his mom; hair spiky, blonde and parted right with a streak of black resembling a lightning bolt, sharp eyes a dark yellow.
Energetic, popular with lots of friends. The kid was smart you could tell and already showing some leadership potential, basically leading the kids at the neighborhood park and at school. He looks up to his mom and wants to be cool like her, especially since he got her quirk, electrification. He tends to throw caution to the wind a bit. A little worrying for his dad.
The older twin, Yuuma on the other hand, black hair with bangs pouring from all sides of his head, deep yellow eyes and slightly round face unlike his brother's sharp one. He was clearly a smart one as well although he was a tad shyer than his brother and had fewer friends, two to be precise. Interestingly enough, he had an outstanding sense of hearing as he could pick up the smallest sound, breathing and to an extent, even a bit on people's feelings (only he knew this last bit). Initially, he thought it was his quirk but no the doctor discovered it was natural ability he was gifted with nothing genetically indicating a quirk awakening.
Of course, the biggest difference between them right now was quirk status. Two months ago, Denki accidentally blow up the lamp bulb by sending in more electric power than it could hold. He was so happy, he ran round the house, screaming at the top of his little lungs that he was going to be a hero. Yuuma was still awaiting his and this may have changed his class' attitude toward him as almost all of them had awakened theirs.
The two were at kindergarten at the moment.
(Saitama Prefecture-
Kindergarten)
Yuuma was sitting by a purple haired kid named Hitoshi Shinso playing with their All Might and Samurai action figures along their blonde female friend, Camie Utsushimi who had one of Midnight.
They heard the sound of children cheering, they turned their heads to see Denki surrounded by the other kids showing off his electric sparks crackling at his fingers again.
"Whoa that's so cool" One commented.
"Yeah! Denki's gonna be an awesome hero." another added.
"Me too!" a redhead boy with eye lasers said with light flashing in his eyes.
"Wonder what Yuuma's gonna get. He's the only one with no quirk"
"Do you think he's… quirkless?" a girl asked quietly.
"Haha…He's quirkless" one mocked while pointing in Yuuma's direction.
Yuuma looked ready to cry because not only could he hear what they were saying but it also seemed true as everyone here had awakened their quirks with the last person getting theirs months ago.
He felt a small hand on his shoulder, "Don't worry Yuu. You'll get your quirk soon and it'll be even cooler", Camie reassured her friend.
"Really?" he asked.
"Yeah don't listen to them" Shinso added.
Yuuma swiped the tears with the back of his hands and then smiled softly. "Thanks guys. You're the best"
"You know it!" Camie chirped with a grin.
"Leave my brother alone! He's not quirkless" Denki countered, "Mom says he would get it before he turns six, he'll get his quirk and it will be awesome" Denki said before walking to put a hand on his brother's shoulder and then turning to address the kids.
"The Kaminari brothers will be the greatest hero team ever! Believe that!" he declared with confidence.
After school, the Kaminari brothers were picked up by their mom.
"How was your day, boys?" she asked keeping her eyes on the road.
"Great!" Denki exclaimed excitedly, "…but they were making fun of Yuuma again" he deflated.
Their mother frowned with her hand on the steering wheel. "That's not very nice. I'll speak to the teacher about that later. Yuu-kun, are you alright?" she asked with concern in her voice.
"I'm good, mommy. I got to play with Hitoshi and Camie today…" he trailed while looking a little sad.
"…so I had fun." He brightened up although with a hint of uncertainty in his voice. She saw his expression through the driver's mirror but kept silent.
They arrived in front of their house. She parked the car and then turned to her older son.
"Listen Yuu-kun, you'll get your quirk and it will be fantastic and even if you don't get it. You've still got the power to do great things in here…"
she pointed at her temple, "…and here." she finished putting her index finger on his chest where his heart is supposed to be.
Touched and encouraged, he beams at her, "Thanks mommy", he leapt to hug her and she smiled lovingly while wrapping one arm round his small back, "You're welcome, baby".
"Me too" Denki joined in for a mother-son group hug before they all burst into laughter.
They all went into the house.
Yuuma walked through the door, "I'll get my quirk and be a cool hero to protect mommy, just like All Might" thought the boy.
With new determination, he ran up the stairs with his brother to go settle in for the day.
Later that evening, Yuuma and Denki were in their room talking about their promised trip to the park tomorrow, it being a Saturday.
Denki went to take a bath.
He hadn't been in two minutes and then a scream was heard.
"AAHHHH!"
"Denki!" Yuuma rushed to see what was up. He opened the door to see his brother at one end of the empty tub squeezing against it while the other end had a cockroach at the edge.
"Help! A bug, I hate bugs!" Denki panicked.
Yuuma giggled a bit, "Calm down Denki, it's just a co…cockro…cockroach." he stuttered while trying to get the pronunciation.
"The teacher talked about it in class and I saw in a picture book the other day." The boy continued.
He kept panicking and then electricity crackled around him.
"Denki?" Yuuma sounding a little concerned.
"Go away bug!" He yelled while releasing electric discharge from his body.
It covered the entire bathtub and portion of the floor but didn't get to the door. Yuuma watched the cockroach fry. When it was over, the cockroach was charred and smoking but Denki was quiet… too quiet.
Yuuma went to tap his brother and when Denki looked up, Yuuma had to stifle a giggle at his expression. It was a uniquely dumb face basically like Saitama's bland one with an open-mouthed smile.
While going," Whee…whee…whee.!" Like a broken record.
"Denki, what's up with your…pfft…face?" Yuuma trying to hold in the laughter and failing.
Yuuma started getting concerned when Denki wasn't responding but kept going, "Whee…whee!"
"Moooom! Something's wrong with Denki" he called. She ran over and took one look at the scene and sighed. Yep! This was her life.
The next day, much to Yuuma's relief, Denki returned to normal. Their mom thought that it was a quirk weakness similar to hers. A quick trip to the hospital revealed that it was indeed quirk backlash.
The doctor handed a report to their mother. She glanced through while the doctor explained that overuse of electrification that is exceeding his immediate wattage limit causes his brain to short-circuit, leaving him vulnerable for about an hour.
Mio digested this information as she also had a similar weakness although it affected her muscle strength rather than her brain leaving her almost immobile. But then again, she had an insanely high wattage limit.
While some more tests on Denki were going on, Mio decided to take Yuuma to the nearby park to play in the meantime after which she and Denki would join them.
(Park)
Yuuma was at the park with other children. They were playing around while he was sitting in a corner waiting because Hitoshi and Camie were supposed to come by later and since he didn't know anyone here he wasn't going to join them.
He was still waiting with his samurai hero action figure when a ball bounced off his head.
He rubbed his head, "Owww!" Yuuma looked up.
Four boys ran up with the one in front, his classmate picking the ball up.
"Hey you're Yuuma…" the redhead in front said recognizing him, "Come play with us" he said excitedly.
"Kuso? No thanks, I'm waiting for Hitoshi and Camie" he replied.
The boy furrowed his brows, "You don't wanna play. You're so weird. Is it 'cause you don't have a quirk?"
Yuuma's eyes widened.
One of the other boys with snake skin asked, "He doesn't have a quirk? That's weird. Mommy said everyone had one."
Another of the boys with completely silver eyes shouted, "No quirk means he's a weirdo"
The last joined in the mockery, "Weirdo look at his hair it looks like a mop. Haha!"
Chants of "Weirdo!" rose from the group and Yuuma's eyes watered and he looked ready to cry. Then a ball of dirt struck his head. It was the one that called his hair a mop.
"Go away, weirdo!" he said gathering a small dirt ball in his hand.
"New game, you're the bad guy and we're the heroes that'll stop you. Face justice!" he said tossing the next ball of dirt.
They started tossing dirt at him and Yuuma started crying and running away while covering his head to keep the dirt away. He ran as hard as his little legs can carry him and the he came to a tree with a rope ladder supposedly for tree house.
In an impressive show of acrobatics, he scaled up the ladder/tree and gets to the branch. Safe from his pursuers, he hugged a branch for dear life while bawling his eyes out.
They got to the bottom of the tree. One tried to climb but the ladder-step gave way and he fell on his butt. 'Ouchie!" he exclaimed, rubbing his bum, teary-eyed.
"Get down bad guy!" the dirt boy yelled looking up with his accomplices.
"Don't be a chicken" the redhead added.
"No way. Leave me alone!" Yuuma whined.
The dirt boy tried throwing some at him, but he was out of reach. Eventually, they all gave up and left.
Some clouds began to gather and rumble.
"Uh-oh" he said under his breath.
It then dawned on him that he is a long way from the ground for his four-year old self. Much to his relief, Hitoshi and Camie happened to arrive at the time.
"Yuuma. What are you doing up there?" Hitoshi asked.
"It's gonna rain soon" Camie said. "So come down"
Yuuma with his eyes still leaking, "The ladder broke and I'm scared."
Camie said," Stay here. I'll get a grown-up" she then sprinted off in the direction of the adults.
As she left, Yuuma kept panicking up a storm and Hitoshi was trying to calm him but before that.
"HELP!" Yuuma screamed. "Momm-"
Just then, a bolt of lightning came from the sky and struck Yuuma. The seething current rushed through his entire body while he writhed in pain and sent him to the ground with an emphatic thump. His vision went black.
He lay on the ground smoking with burns all over and his hair had changed color. Hitoshi was screaming his name, while Camie arrived on the scene with an adult running behind her. Yuuma was taken to the hospital.
(Back at the hospital)
Mio and Denki were about heading to the park when they saw a child being carried by a man with Hitoshi and Camie running after him so she went to inquire.
"Camie, what happened?" The older woman asked.
Camie turned to her in tears, "Yuu got hurt."
"What?!" Mio shocked
She took a closer look at the blonde child in the man's hands
"Yuu-kun?" she recognized the face and rushed to her son, took him gently from the stranger and ran to the emergency room while yelling for a doctor.
She happened to encounter the female doctor stepping out of the office.
"Kaga-sensei, Yuu-kun got struck by lightning!"
"What?!" the doctor was shocked but quickly recovered, calling for stretcher and then mounting the boy on it before rushing to tend to him.
"Save him…please" she told the doctor.
"I'll do my best" The doctor turned and replied, before rushing off to the emergency ward.
Left alone, Denki turned to his mother. Grabbing her shirt, teary-eyed.
"Mommy, is...is he gonna be okay?"
"He'll be okay, sweetie. He'll be just fine." She said pulling him into a hug.
It was an agonizing wait but after a couple hours, the doctor stepped out of the room with a neutral expression on her face. Denki and his mom rose from the seats.
"Kaga-sensei, how is he?" she asked.
The doctor looked at them for a moment before letting out a sigh and then started speaking.
"He's been stabilized. He suffered a few burns all over but nothing scarring. His insides are in good shape and he's unconscious for now. We don't know what caused it but his hair color also seems to have changed. But he'll live for certain."
"Blonde? Wait that's not important" Mio thought.
"Thank you Kaga-sensei" she said, bowing "Can I see him?"
"You're welcome but your boy is a strong one." the doctor replied, smiling
"Anyway, you're free to check on him." She led them through the door.
Stepping into the ward, they could see Yuuma unconscious on the bed wrapped in bandages with a respirator on his face with nodes and other equipment on him.
Mio moved to his bedside and clutched his tiny hand in hers.
"You're going to be fine, baby. Mommy is here with you." she whispered to his sleeping form.
Denki also near the bed looked worried while whispering, "Wake up soon, Yuuma. So we can play together again."
While this was going on, Yuuma found himself in a space of pure darkness.
"Hello! Is anyone here?" he squeaked. There was no response before a sudden flash of light and he shielded his eyes from the sudden brightness. He opened them again and found himself in a room of an ancient Japanese mansion (Taisho era). He looked around the unfamiliar room noticing the smooth autumn red wooden floors under his bare feet and shoji (sliding door).
He moves towards the door, and then it opens suddenly to reveal a grotesque creature, a demon with four eyes and a really long tongue rubbing along the floor.
Yuuma's eyes widened with fear and then he stumbled back falling on his butt.
"Stay back, please. Don't come any closer." He panicked as the monster started cackling and crawling towards him while he kept scurrying backwards until his back hit the wall.
As the beast got closer, it kept flailing its tongue flicking saliva all over the floor. Yuuma cornered, shut his eyes tightly, whimpering as the demon approached.
"Mommy…Daddy…Denki" he thought as the beast tretched his tongue towards him.
Then he heard
Slash! Plop!
"Ah!" startled the demon, grabbing his tongue.
Yuuma opened his eyes at the sound and was greeted by the sight of a lump of the demon's tongue at his feet. He retracted his leg quickly in disgust and fear before looking up.
In front of him, facing the demon, was a person wearing in a yellow haori patterned with white triangles, his hair blonde with orange highlights. The person said nothing to Yuuma as he got into a quick-draw sword stance, and exhaled.
"Thunder Breathing…", was all Yuuma heard in his shock as he all saw was a yellow blur trailed by blue lightning and the next thing, the head of the demon was sliced off. It fell to the ground and started to turn to dust while the blur became a person again.
The person stood, turning to Yuuma and for the first time, Yuuma could see his face. He noticed that it was a young man wearing in a yellow haori over what looked to be a black uniform with white edges, similar yellow patterned cloth tied to his shins, wooden sandals and a white scabbard on his hip. The swordsman sheathed his blade and started walking towards him. Taking a good look at his face and he noticed that although the swordsman was blonde and his eyes were closed, he looked exactly like him just older.
Yuuma got on his feet and tried to communicate, "Umm…thank you for your help, sir." He said, bowing before straightening up.
"I'm Yuuma, may I know your name?" he asked as the swordsman approached him, eyes still closed.
The swordsman simply ignored him, stretched his hand towards him and touched his forehead, sending a surge of blue and yellow lightning into him. Yuuma felt the massive surge of energy through his body and then-
His eyes shot open.
