[POV: Denki Kaminari]
Two Weeks Later...
It had been two weeks since my past life memories came crashing back into my five-year-old brain like an unwelcome freight train.
Two weeks of adjusting, Two weeks of pretending to be a kid.
Two weeks of slowly coming to terms with the fact that this was my reality now—whether I liked it or not.
'And honestly? I'm getting pretty good at this whole "second life" thing.'
I'd gotten used to living in this small body. Used to answering to the name "Denki Kaminari" instead of my old one. Used to the routine of this household and the people in it.
After all, I didn't have much choice in the matter.
This was my life now, and complaining about it wouldn't change anything. So instead, I focused on what I could control—starting with getting to know my new family members better.
My father, Kenji Kaminari, insurance agent extraordinaire and professional workaholic. My mother, Narihana Kaminari, Pro Hero and equally dedicated to her career.
'Those two are basically ghosts,' I thought with mild amusement, watching my father scarf down breakfast while simultaneously checking emails on his phone. 'They're only home long enough to sleep, shower, and grab food before vanishing again.'
It was currently 7:30 AM, and we were all seated around the dining table—a rare moment when the entire family was actually in the same room.
My mother sat across from me, still in her hero costume from the night shift, dark circles under her eyes as she sipped coffee like it was the elixir of life. Her lightning-blue hair—a side effect of her Quirk—was pulled back in a messy ponytail, and she looked about three seconds away from face-planting into her toast.
My father, meanwhile, was already dressed for work in a crisp suit and tie, looking far too put-together for someone who'd gotten maybe five hours of sleep.
"Denki-kun," my mother said suddenly, pulling me from my thoughts. Her voice was tired but warm. "How are you feeling? Your Quirk hasn't been giving you any trouble, has it?"
I shook my head, putting on my best "innocent five-year-old" smile. "Nope! It feels really cool, Kaa-san! Sometimes it tingles, but it doesn't hurt."
She smiled, reaching across the table to ruffle my blonde hair. "That's good. If you ever feel anything strange, you tell us immediately, okay? Newly awakened Quirks can be unpredictable."
"Okay!"
My father glanced up from his phone, offering me a quick smile. "You're doing great, son. I'm proud of you."
'Yeah, you said that two weeks ago too,' I thought but didn't say. 'Right before you got a phone call and disappeared for three days.'
Don't get me wrong—they did show me affection. In the few moments we actually shared together as a family, they were kind, attentive, even loving. My mother would ruffle my hair and ask about my day. My father would occasionally bring home small gifts—toys, books, candy.
But when it came to their work?
They were gone.
Physically present sometimes, but mentally already out the door, chasing their next case or rescue mission.
If I didn't have my past life memories—if I was just a normal five-year-old—I probably would've thought they didn't love me. That I was some kind of burden they'd rather not deal with.
But I did have those memories, mind of an adult and I could read between the lines.
'They do care,' I acknowledged, watching my mother fight back a yawn. 'They just... have their priorities. Their own ways of showing affection. Their own lives beyond being parents.'
I didn't blame them. Everyone had their own goals, their own dreams, their own responsibilities. In a world like this—where villains could strike at any moment and one wrong move could mean the difference between life and death—I understood why they threw themselves into their work.
Still...
'This situation is actually perfect for me.'
As cold as that sounded, it was true.
Because of my parents' constant absence, I had time. Freedom. Space to experiment with my Quirk without constant supervision. Hours and hours where I could train, plan, and prepare without anyone questioning why a five-year-old was acting weird.
'It's a blessing in disguise,' I thought, taking a bite of my rice. 'Because let me tell you—pretending to be a normal kid 24/7 is exhausting.'
Some people might wonder why I bothered with the act at all. Why not just be myself? Why waste energy pretending to be an innocent, carefree child?
The answer was simple: survival.
Imagine this scenario: a five-year-old kid suddenly changes his entire personality overnight. Starts speaking with adult vocabulary. Shows understanding of complex concepts he shouldn't know. Demonstrates strategic thinking and emotional maturity way beyond his years.
Now imagine one of his parents is a Pro Hero who's seen all the shit life can throw at you—including villains with mind-control Quirks, possession abilities, and personality-altering powers.
'Yeah, that would raise some serious red flags.'
My mother would immediately suspect something was wrong. She'd start asking questions. Maybe bring me to a doctor. Maybe even a hero with a mental Quirk who could scan my brain for abnormalities.
And then what?
Best case scenario: they think I'm some kind of genius prodigy and my life becomes a media circus.
Worst case scenario: they discover I'm somehow not their real son, and things get very complicated very fast.
'No thanks. I'll pass on that headache.'
So I acted. I played the part. I spoke like a child, thought like a child—at least on the surface—and made sure never to slip up in front of my parents or anyone else who might find it suspicious.
Call me paranoid if you want.
But in a world where the main villain could steal and stockpile Quirks, where Nomu existed, where children got kidnapped and experimented on?
Better safe than sorry.
"Denki-kun, don't forget to drink water after breakfast!" my mother called as she stood up, already heading toward the door.
"I won't, Kaa-san!"
She paused in the doorway, glancing back with a soft smile. "Be good for Megumi-san today, okay?"
"I will!"
And just like that, she was gone—off to save the world or file paperwork or whatever Pro Heroes did during the day.
My father followed five minutes later, still on his phone, barely registering my goodbye wave.
The front door clicked shut.
The house fell silent.
It felt weird for the couple to leave a five-year-old alone in the house with no one else around. I didn't question it—or wonder if they'd lost their minds—because it worked in my favor, and because I knew Megumi would be arriving soon.
Still, I couldn't shake how strange it was for them to leave their child like that.
I finished my breakfast alone, cleaned my dishes like a good boy, and then headed upstairs to my room.
The moment I closed the door behind me, I dropped the innocent act like a heavy coat.
'Finally. Some peace and quiet.'
I walked over to my desk—a small wooden thing covered in crayons and coloring books for show—and pulled open the bottom drawer.
Hidden beneath a stack of old drawings was a notebook.
Not just any notebook. My personal future events notebook.
I pulled it out carefully, running my fingers over the plain cover before flipping it open to a random page.
To anyone else, it would look like complete gibberish. A chaotic mess of emojis, symbols, scattered English words, fragments of Japanese, even some Hindi phrases I remembered from a friend in my past life.
But to me?
It was a timeline. A guide and a reference manual for the future.
I'd spent the last two weeks writing down everything I could remember about the plot of My Hero Academia—every major arc, every significant event, every character introduction and death that I could recall.
'Because I have about eleven years before the plot officially kicks off,' I thought, scanning the pages. 'Eleven years before Izuku Midoriya meets All Might. Eleven years before U.A.'s entrance exam.'
And in that time, my memories might fade. Details might blur. I might forget crucial information that could mean the difference between life and death.
So I wrote it all down in a code only I could decipher.
📺🔥👦 = U.S.J. Arc - Villain attack on Class 1-A during rescue training.
💪🔥😡 = Sports Festival - Bakugo wins, Todoroki's backstory revealed.
🗡️🩸🦸 = Stain Arc - Hero Killer attacks Hosu, Iida's revenge.
I'd divided the timeline into sections, each marked with symbols and emoji combinations that represented major plot points.
The Entrance Exam ⚡📝🤖
The Battle Trial 👊💥🏢
The Kamino Incident 🦹♂️😈⚡
The Shie Hassaikai Raid 🎭💊👧
The War Arc ⚔️💀🌊
Under each heading, I'd written as many details as I could remember—character names, outcomes, casualties, turning points.
Some entries were clear. "Midnight - dies during War Arc protecting students"
Others were frustratingly vague. "Something happens with Hawks and Endeavor??? Double agent stuff???"
'I really should've paid more attention during some of these arcs,' I thought with a grimace. 'But at least I've got the major beats down.'
I flipped to a page near the back labeled PEOPLE TO SAVE in code language and stared at the list.
Midnight (War Arc), Star and Stripe (vs Shigaraki), Sir Nighteye (Overhaul fight) and few others.
'I don't know if I can save all of them,' I admitted silently. 'Hell, I don't know if I can save any of them. But I have to try.'
I closed the notebook and carefully hid it back in the drawer, covering it with drawings again.
'Eleven years,' I thought, clenching my small fists. 'Eleven years to get strong enough to make a difference.'
Now, apart from documenting the future, I'd also been spending the last two weeks doing something far more practical: Experimenting with my Quirk.
And by "experimenting," I mean playing with every electronic device I could get my hands on without raising suspicion.
Remote-controlled cars. Battery-powered toys. Megumi's phone when she wasn't looking. The TV remote. My nightlight.
'Sorry, Megumi-nee. Your phone's battery life has been sacrificed for science.'
Through trial and error—and okay, maybe accidentally short-circuiting three toys in the process—I'd learned quite a bit about what I could and couldn't do.
Discovery #1: I have excellent control for a newly awakened Quirk user.
Most kids my age would be sparking randomly, unable to turn their power on or off consistently. But me? I could generate electricity at will, maintain it for extended periods, and stop it cleanly without any lingering discharge.
'Definitely above average,' I noted with satisfaction. 'Either I'm naturally talented, or my adult mind gives me better focus. Probably both.'
Discovery #2: I'm basically a living portable power bank.
After several experiments with rechargeable batteries and electronic toys, I'd figured out how much electricity was needed to charge different devices without frying them.
It had taken practice—and yeah, three sacrificial toys that I may or may not have "accidentally" killed—but now I could reliably charge things without turning them into expensive paperweights.
'Portable Power Bank Denki, at your service,' I thought with amusement.
Discovery #3: I can sense electricity in nearby devices.
This one was interesting. When I focused, I could feel the electrical currents flowing through gadgets near me—like a sixth sense specifically attuned to anything powered by electricity.
I could tell when Megumi's phone was at 47% battery. I knew exactly when the TV was on standby mode versus fully powered down. I could sense the flow of current through the house's wiring.
'It's like having electrical echolocation. Pretty damn useful.'
Discovery #4: I can absorb and manipulate external electricity—but only through direct contact.
This was both exciting and limiting. I could drain a battery completely by touching it, absorbing its stored energy into my body. I could also short-circuit devices by overloading them with electricity.
But I had to be touching them to absorb the electricity.
'So my range is basically zero,' I thought. 'That's... less than ideal. Something to work on.'
Discovery #5: My current output is... average at best.
Yesterday, I'd convinced Megumi-nee—yeah, I'd gotten used to calling her that after she lit up like a Christmas tree the first time I did it—to let me "test my full power" in the backyard.
I'd released everything I had.
And the result?
I generated enough electricity to power the lights in my bedroom for approximately fifteen seconds.
'Fifteen... Seconds.'
I'd done the math based on what I remembered from high school physics. Assuming standard LED bulbs at about 10 watts each, and my room having four of them...
I was outputting roughly 40 watts of electricity at maximum capacity.
For reference? A standard household outlet in Japan provided 1,500 watts continuously.
'Yeah. I'm basically a very inefficient flashlight right now.'
But that was to be expected. I was five years old. My Quirk had awakened literally two weeks ago. Expecting to output megawatts of electricity at this age would be like expecting a toddler to benchpress a car.
Still, it meant I had work to do. A lot of work.
Because I had plans. Big plans. Flashy plans that required way more juice than my current 40-watt output.
I wanted to use Lightning Cloak like the Raikage from Naruto—coating my entire body in electricity to boost speed and power.
I wanted to perform Chidori—channeling concentrated electricity into my hand for devastating piercing attacks.
I wanted to pull off moves like Enel from One Piece—transforming into lightning, moving at insane speeds, reshaping my body.
Hell, if I could manage it, I wanted to do Volt Tackle like Pikachu, or Thunder Breathing techniques like Zenitsu from Demon Slayer, or even recreate Laxus's Lightning Dragon attacks from Fairy Tail.
'But for any of that to work, I need two things: way more storage capacity, and way higher maximum output.'
My body was the limiting factor. A five-year-old's body simply couldn't handle or store large amounts of electrical energy safely.
So I needed to train. Carefully and Smartly. And I needed a plan.
I'd spent the last five days formulating a training regimen that would allow me to grow stronger without accidentally killing myself or drawing unwanted attention.
'Step One: Increase my maximum electrical output.'
The theory was simple, just like how muscles grow when you stress them beyond their normal capacity, my Quirk should strengthen if I regularly pushed it to its limits.
So I needed to constantly release most of my stored electricity—drain the tank, let it refill, drain it again.
'I'll need to be smart about this,' I thought. 'Can't just randomly blast lightning in my backyard without someone noticing. Need a cover story. Need a method that looks like innocent play.'
I had a few ideas, but they'd have to wait until I had more freedom to experiment.
'Step Two: Master Thunder Breathing and Total Concentration.'
This one came straight from Demon Slayer. The concept was brilliant in its simplicity, control your breathing to maximize oxygen intake, boost your physical capabilities, and maintain peak performance for extended periods.
If I could master Total Concentration Breathing—maintaining that enhanced breathing pattern 24/7, even while sleeping—my body would naturally grow stronger, faster, more durable.
'And unlike Quirk training, nobody will think it's weird if a kid practices breathing exercises. I can just say I saw it on TV.'
Which I actually had done three days ago, weaponizing my puppy-dog eyes against Megumi-nee until she let me watch yoga and meditation videos.
'Never underestimate the power of looking adorable,' I thought smugly. 'Works every time.'
I'd spent the last three days practicing the breathing techniques I'd seen—deep inhales through the nose, controlled exhales through the mouth, focusing on expanding my diaphragm.
And shockingly? I was good at it. Like, unnaturally good.
Within three days, I could already regulate my breathing pattern consistently, maintaining the rhythm even while moving around or doing other activities.
'Once again it's either I'm naturally talented at this, or my adult mind gives me better control over my body,' I mused. 'Probably both. I'll take it as a win either way.'
It was a minor advantage—nothing gamebreaking—but every little bit helped.
'Step Three: Use electricity to temper my body and increase my physical capabilities.'
This was the big one. The foundation of everything else.
I was naturally resistant to electricity—came with the Quirk, apparently—but I wasn't immune. If I pumped enough voltage through my body, I could still hurt myself.
But that resistance also meant I could do something most people couldn't, Run electrical currents through my muscles to stimulate them, strengthen them, force them to adapt.
'It's like those electronic muscle stimulators athletes use,' I reasoned, 'but way more intense. And I can do it whenever I want, for free.'
The plan was to constantly circulate low-level electricity through my body—just enough to stimulate my muscles and nerves without causing damage.
Over time, this would Increase my physical strength, Improve my reaction speed, Build up my electrical resistance, Train my body to handle higher voltages.
'Basically, I'm going to turn myself into a speed-type fighter,' I decided. 'Like the Flash, but with actual lightning powers instead of magic speed force bullshit.'
Now, let me be clear, I wasn't obsessed with being the Flash.
But pragmatically speaking, at five years old with a fragile body and limited energy reserves, focusing on speed made the most sense.
I couldn't build muscle mass like All Might—not yet, not at this age.
I couldn't practice complex combat techniques—I was too small and too weak.
But I could work on speed, reaction time and agility.
'Eleven years,' I reminded myself. 'I've got eleven years before U.A.'s entrance exam. Eleven years to build the foundation. First, become a speed-type fighter. Then, once my body matures and my reserves grow, I can branch out into power-type techniques.'
It was a long-term plan. Patient and methodical. But I had time.
"Denki-kun! Come find me!"
Megumi-nee's cheerful voice echoed through the house, snapping me out of my thoughts.
I was currently in the middle of a "game"—hide and seek with my babysitter.
But this wasn't just play. This was training.
'Because everything can be training if you're creative enough,' I thought with a grin.
I closed my eyes, focusing on the sensation running through my body.
Right now, I had a low-level electrical current flowing through my entire nervous system—from my brain down my spine, through every nerve cluster, into my muscles.
It felt weird. Like drinking three energy drinks and then trying to walk normally. My movements were slightly jittery, my muscles twitching randomly as they adjusted to the constant stimulation.
'This is going to take a while to get used to,' I admitted, taking a careful step forward.
But that wasn't the only thing I was practicing.
Megumi-nee had a Quirk called Transparency Field—she could create a field of invisibility around herself and anything she was touching. It only lasted for a short time and could only affect one or two objects at most, but it was still pretty useful.
Right now, she was using it to hide somewhere in the house, completely invisible.
And I was trying to find her using my developing electrical sense.
'The human body generates bioelectricity,' I recalled from my high school biology classes. 'The brain sends electrical impulses through neurons to control movement. The heart generates electrical signals to regulate its beating. Every muscle contraction involves electrical charges.'
If I could learn to sense that bioelectricity—to detect the electrical signals produced by a living person's nervous system—I could potentially develop a radar-like ability.
A way to sense people even through walls or in complete darkness.
'But that's advanced stuff,' I acknowledged. 'Right now, I can barely sense anything beyond electronic devices. Detecting bio-electricity is going to take a long time to develop.'
Still, practice was practice.
I moved through the living room carefully, maintaining my electrical circulation while trying to sense any anomalies in the environment.
Nothing.
I checked the kitchen.
Nothing.
The bathroom?
Still nothing.
"Having trouble, Denki-kun?" Megumi-nee's voice came from behind me.
I spun around—too quickly, my electricity-amped reflexes making me stumble slightly—to find her standing in the hallway with a playful smile.
"Aww, you found me!" I said, pouting like a defeated five-year-old.
She giggled and scooped me up in a hug. "You're getting better! You almost found me that time!"
'No I didn't,' I thought wryly. 'I failed completely. Couldn't sense her at all.'
But I just smiled and hugged her back. "One more game?" I asked hopefully.
"Just one more," she agreed.
.
.
.
**Later That Evening**
"Megumi-neesan, can we watch more yoga videos?" I asked while putting on my best innocent child expression.
She looked up from her phone, slightly confused. "Yoga? Again? Denki-kun, you've been watching those a lot lately."
"They're cool!" I insisted. "The people can bend in funny ways!"
'And they teach breathing techniques and body control that I desperately need,' I added silently.
Megumi-neesan laughed. "Alright, alright. You're such a weird kid sometimes."
'You have no idea,' I thought with an internal smirk.
We settled on the couch, and she pulled up a yoga and meditation video on the TV. I watched intently, mimicking some of the stretches and breathing exercises while electricity subtly flowed through my system.
It was exhausting. Running electricity through my body while moving and maintaining breathing control felt like trying to juggle while riding a unicycle. Everything required intense concentration, and my child body tired quickly.
But I didn't stop.
That was fine.
I'd work with what I had. Push my limits. Break through my ceiling again and again until I became someone who could change this world's future.
.
.
.
Days Turned to Weeks, Weeks Turned to Months
And I fell into a routine—one that probably would've looked insane to any outside observer, but felt perfectly normal to me.
At 6:00 AM daily, I woke up before dawn every day and immediately started exercising.
Push-ups until my arms gave out, Sit-ups until my core screamed, Squats and lunges until my legs shook.
All while maintaining Thunder Breathing and circulating electricity through my body.
'I'm five years old and doing a workout routine that would make a marine cry,' I thought during one particularly brutal session.
But I was careful. I listened to my body. I took rest days when needed.
Because as Master Roshi wisely said: "Work hard, study well, and eat and sleep plenty."
I followed that philosophy religiously.
Rest was just as important as training. Recovery allowed the body to adapt and grow stronger. Overtraining would only break me down.
So I made sure to balance it. Train hard, rest properly, eat nutritious food, and sleep eight to ten hours every night. My body was still developing—I had to take care of it if I wanted it to support my ambitions later.
At 8:00 AM, If my parents were home, I'd eat with them and practice being a normal, cheerful child.
If they weren't—which was most days—I'd eat with Megumi-nee and review my notes.
At 9:00 AM, This was my favorite part of the day.
Megumi-nee would take me to the park several times a week. While other kids played on swings and slides, I'd run laps around the park. To anyone watching, I was just an energetic child burning off excess energy.
In reality?
I was running laps with electricity coursing through my legs, training my muscles to move faster.
I was practicing Thunder Breathing while sprinting, building up my lung capacity.
I was subtly testing my electrical output, seeing how much power I could generate without sparking visibly.
"You have so much energy, Denki-kun!" Megumi-nee would laugh, watching me zoom around.
'If only she knew,' I thought with amusement.
At 12:00 PM, I'd eat, rest, and spend time reading or watching educational content.
Sometimes I'd convince Megumi-nee to let me watch hero fight footage online.
'Gotta study the combat styles of this era's heroes,' I reasoned. 'Know your enemy and all that.'
At 2:00 PM, Afternoon sessions focused on control.
I'd practice generating precise amounts of electricity. Starting and stopping on command. Maintaining output for extended periods.
Sometimes Megumi-nee would play hide-and-seek with me, unknowingly helping me train my sensory abilities.
'She'd probably be horrified if she knew I was turning playtime into a training montage,' I thought guiltily.
But not guilty enough to stop.
At 8:00 PM, If my parents were home, we'd eat together.
If not—again, most days—I'd have dinner with Megumi-nee and then get ready for bed.
At 9:00 PM, After my parents thought I was asleep, I'd quietly practice electricity control in my room.
Generating sparks between my fingers, Circulating current through my body, Pushing my limits bit by bit.
'Can't let a single day go to waste,' I told myself.
.
.
.
Soon, months passed.
My control over electricity improved steadily. I could maintain the flow through my body for longer periods. My storage capacity increased—not dramatically, but noticeably. My physical conditioning advanced faster than a normal child's, though I was careful not to develop in ways that would seem unnatural.
The bioelectrical sensing remained elusive. I could sometimes feel vague presences when people were very close, but nothing concrete. Nothing reliable.
'Long-term project,' I reminded myself. 'Rome wasn't built in a day. Neither are sensory techniques.'
My parents remained busy. I saw them briefly each day, shared meals when our schedules aligned, and received their affection in small doses.
It was enough.
More than enough, actually, because their absence gave me the freedom to train without supervision.
Season changed. Summer heat gave way to autumn cool, then winter cold, then spring warmth.
A full year passed.
One year of training. Of preparation. Of slowly building the foundation for what I would become.
I was six years old now.
Still a child by any measure. Still weak compared to the heroes and villains of this world. Still years away from UA and the events I remembered from canon.
But I was stronger than I'd been. Faster and more controlled.
