Location: Naruhata Ward – Kaito's Apartment
Saturday |
03:00 PM (One and a Half Months Later)
Strum.
The bright, acoustic chord echoed through the living room of Unit 203.
The apartment was packed.
The coffee table was pushed to the side, replaced by empty pizza boxes and cold cans of soda.
Kazuho sat cross-legged on the sofa, her headphones resting around her neck.
She was holding Kaito's digital audio tablet, staring at the mixing tracks for "Peace Sign" with absolute obsession.
"Kaito, I still don't understand it," Kazuho groaned, dragging a hand down her face. "You wear gray suits. You drink black coffee. You calculate supply chain logistics for fun! How do you have the soul of a platinum-selling rockstar?! You're even better than me."
"Yeah, man," Koichi chimed in, grabbing another slice of pepperoni pizza. "The first time you played that track, I legitimately thought you hired an underground-band to record it in secret."
Kaito sat behind a compact electronic drum kit he had purchased the week prior.
He held two wooden drumsticks, his posture perfectly straight.
"Music is simply organized mathematics, Kazuho," Kaito stated, adjusting his glasses. "It relies on predictable time signatures and measured frequencies. It is not fundamentally different from traffic management."
Makoto laughed warmly from the kitchen counter, taking a sip of her tea.
"Haha. Don't try to figure him out, you two. You'll just get a headache," Makoto smiled. "Just appreciate the free backing tracks."
Nom-nom.
Nom-nom.
"Yeah, you're right, Makoto-senpai. He would just tell you that he knows a little bit of everything," Koichi replied while munching on his pizza.
"Ooohhh, I'm so jealous... I tell you, Kaito-san is really hiding something. He knows everything," Kazuho chimed in next.
_-_-_-_-_-_
Sitting on a small stool near the television was Tamao.
She was Iwao's daughter.
She wore a simple yellow sweater, tapping her foot lightly to the rhythm Kaito had just played.
Tamao wasn't a stranger here anymore; over the past half month, she had become a staple in this apartment, completely adopted by the atmosphere.
For years, Tamao had suffered a severe traumatic event that left her practically catatonic.
It was basically a waking nightmare. Tamao was trapped inside her own head.
Forced to watch through her own eyes while a parasite used her hands to hurt her family and someone.
She wasn't totally "gone"; she was still in there. Every time she tried to fight back or scream, the Queen Bee just pushed her back down, using her deepest insecurities as leverage to keep her quiet.
It was less like being asleep and more like being a passenger in a car that's crashing into everything you love, and you can't even reach the brakes.
When Iwao first brought her around, she was incredibly skittish and prone to panic attacks.
But Kaito didn't rely on slow therapy. Whenever Tamao visited, Kaito would look at her.
He would visualize the damaged neural pathways in her brain, the lingering spikes of cortisol, and the chemical imbalances of fear.
Snap.
Kaito would silently edit her biology. Little by little, he smoothed out the trauma. He didn't erase her memories, but he quietly deleted the biological panic attached to them.
Because of Kaito's silent intervention, Tamao was healing faster than any doctor thought possible. She was comfortable here now.
And more importantly, she loved music.
Kaito stood up from the drum kit. He walked over to the guitar stand and picked up his jet-black Fender Stratocaster.
He held it out toward Tamao.
Tamao blinked, looking up at him with a soft, surprised smile.
"You want me to play the electric?" she asked, her voice gentle but no longer trembling.
"Your father mentioned you practiced acoustic guitar all week," Kaito said, his voice level and calm. "The fretboard logic translates directly to an electric model. Hold it."
Tamao reached out, taking the heavy guitar and resting it on her lap.
Her fingers instinctively found the neck, completely familiar with the instrument.
Iwao Oguro leaned against the hallway doorframe.
He crossed his arms, holding his breath as he watched his daughter interact so normally.
"I composed a new track yesterday," Kaito said, walking back to his drum kit. "It is a highly energetic, fast-paced song. I will handle the percussion and the vocals. You will play the lead rhythm."
"I don't know the chords, Kaito-san," Tamao pointed out, though her hands were already in a ready position.
"I will guide you. Put your fingers on the E minor chord," Kaito instructed, picking up his drumsticks.
Tamao pressed her calloused fingertips against the steel strings.
Tap. Tap. Tap. Tap.
Kaito counted off the tempo by hitting his drumsticks together.
Suddenly, Kaito slammed the sticks onto the snare and hi-hat.
CRASH!
A driving, incredibly fast-paced drumbeat exploded into the room.
Kaito's hands moved with blinding speed, setting a hype-filled rhythm.
"Play!" Kaito commanded.
Tamao strummed the chord. The amplifier carried the crisp, heavy, distorted sound perfectly.
"Transition to C! Then D!" Kaito called out over the drums.
Tamao's eyes locked onto the fretboard. Her muscle memory engaged instantly.
She slid her hand down the neck, striking the chords in perfect time with Kaito's relentless beat.
Then, Kaito leaned toward the condenser microphone mounted to his drum rack.
His flat voice vanished, replaced by a soaring, powerful rock tenor.
"Shizukesa ga shimikomu you de... Iki wo tometa gozen goji..."
(As if the silence is soaking in... holding my breath at 5 AM...)
Kazuho's jaw dropped. Koichi stopped chewing his pizza, his eyes wide.
"Hijou kaidan de tsume wo kamu, asu wa docchi da?!"
(Biting my nails on the fire escape, which way is tomorrow?!)
"THE DAY HAS COME!"
It was the iconic opening to "The Day."
Kaito hit the kick-drum heavily, driving the hype higher.
He nodded at Tamao. "Build the tension!"
Tamao strummed faster, a massive, genuine smile breaking across her face.
She leaned into the music, her head bobbing to the relentless rock rhythm.
"Keshite akenai yoru mo... Furishikiru ame mo..."
(The night that never seems to end... The relentlessly falling rain...)
"Shukumei tte yatsu wo moyashite! Boso suru kigou deai koto!"
(Burn up what they call destiny! A runaway sign, encountering it!)
Kaito delivered the chorus with flawless, fiery passion, his drum solo syncing perfectly with Tamao's aggressive guitar sweeps.
He pushed his vocal range higher, completely immersing the living room in a wall of raw, emotional sound.
When the song finally ended, Kaito hit the crash cymbal one last time.
Tssshhhhh.
The room was completely silent for three seconds as the guitar feedback faded out.
Clap.
Clap.
Clap.
Then, Kazuho and Koichi erupted into loud cheering and applause.
Makoto clapped brightly from the kitchen, laughing in sheer amazement.
"That was incredible!" Koichi yelled.
Tamao sat on the stool, breathing heavily. She looked down at the guitar in her hands, and then she looked up at her father.
She beamed, her eyes shining with pure, unburdened happiness. It was the brightest she had looked in years.
Iwao swallowed hard. He rubbed his scarred face, his throat tight with emotion. He looked at his smiling daughter, then stared down at the hardwood floor.
"If only your mother could see you right now," Iwao murmured under his breath, so quietly that no normal person could have heard it. "If she just wakes up... we'll finally be whole again."
Behind the drum kit, Kaito's hands froze.
His senses picked up the whisper perfectly.
Kaito was briefly, genuinely stunned.
In all the months he had known Iwao, Koichi, and Kazuho, none of them had ever mentioned Iwao's wife.
Kaito had assumed she was simply out of the picture.
But it's far from the truth.
[A/n: Tamao had been rescued early in this timeline, meaning her mother hadn't died. She was still alive, trapped in a catatonic coma in some hospital room.]
Kaito blinked, his mind immediately cataloging this new, vital piece of data.
"Good work, Tamao," Kaito said, masking his realization. "You're a natural. Your transitions were slightly delayed..."
"Thank you, Kaito-san!" Tamao replied eagerly, carefully setting the guitar back on its stand.
The apartment was filled with laughter and warmth as Kazuho rushed over to hug Tamao.
Kaito adjusted his glasses, surrounded by his found family, his mind already spinning with a new, quiet objective.

Location: Tokyo – Team Idaten Headquarters
Thursday | 04:30 PM
The dispatch floor of Team Idaten was no longer a chaotic nightmare.
It was a well-oiled machine.
Kaito stood in the center of the room, wearing his beige trench coat and a headset. He stared at the massive digital map on the wall.
A multi-car pileup had completely blocked the Tokyo Bay Bridge.
"Enigma, you are approaching the wreckage from the south," Kaito ordered over the radio, his voice cutting through the silence of the dispatch room. "Do not engage the burning sedan. Focus entirely on structural stabilization of the guardrail."
"Copy that, Manager!" Enigma's voice crackled back instantly.
"Bigshot, deploy your impact-foam on the overturned tanker truck," Kaito commanded.
"Onemu, you have sixty seconds to extract the civilians from the blue minivan before the fuel ignites. Move."
There was no arguing. There was no hesitation.
The sidekicks executed the commands with terrifying efficiency.
Kaito's route mapping ensured that none of the speed-heroes crossed paths or stole each other's momentum.
"Tough Grab," Kaito said, tracking a specific green dot on his monitor. "The bridge cabling is snapping. Intercept."
"I'm on it! Got 'em!" Tough Grab shouted over the comms.
"Watchbird, clear the aerial perimeter for the medical evac choppers," Kaito finished.
Click
He pressed his stopwatch.
"Mission accomplished," the lead dispatcher announced. "Zero civilian casualties. The fire is contained. Highway cleared in four minutes and twelve seconds."
Kaito stopped the watch. He made a single checkmark on his clipboard.
Thirty minutes later, the heavy steel doors of the dispatch floor slid open.
The strike team returned. Enigma, Tough Grab, Bigshot, Onemu, and Watchbird walked in.
They were covered in soot and sweat, but they were grinning from ear to ear.
When Kaito first arrived a month and a half ago, they were terrified of him.
He had brutally demoted twenty-six of their friends.
But as the weeks passed, the fear turned into absolute reverence.
They realized Kaito hadn't ruined their agency; he had made them invincible.
Because of him, they were saving more lives than ever before, and not a single sidekick had been injured on duty.
Tough Grab, a massive hero with heavily armored gauntlets, walked straight up to Kaito's desk.
"Manager Arisaka," Tough Grab said, giving a respectful bow.
"Your intercept trajectory was optimal today, Tough Grab," Kaito stated without looking up from his paperwork. "Your reaction time has improved by twelve percent."
"Thanks to you mapping the blind spots, sir," Tough Grab grinned. He rubbed the back of his neck. "Listen, the team broke our monthly save-record today. We're heading down to the Ginza district for yakiniku to celebrate. We... we wanted to know if you would join us."
The other sidekicks held their breath, waiting for the cold, corporate rejection.
Kaito paused. He looked at the paperwork, then looked up at the team of exhausted, hopeful heroes.
"I prefer beef tongue," Kaito said evenly. "If the establishment serves it, I will attend for exactly one hour."
Bigshot pumped his fist in the air. "Yes! Drinks are on me, Manager!"
Tensei Iida stood near the glass wall of his private office.
He wore his Ingenium armor, watching his sidekicks laugh and joke around Kaito's desk.
Tensei smiled warmly.
Kaito had been right. Running an agency like a charity only hurt people.
By enforcing strict efficiency, Kaito had forged a genuine bond of trust.
Team Idaten was finally a true family, built on competence rather than pity.

Location: Musutafu – Midoriya Household
Friday | 07:00 PM
The rain battered the windows of the small apartment in Musutafu.
Izuku Midoriya sat at the dining table, chewing a piece of fried pork cutlet. He wore a slightly oversized, plain yellow t-shirt.
Inko Midoriya sat across from him, sipping a cup of hot tea.
Lying on the sofa in the living room was Kuro.
The black-and-white cat was stretched out lazily, his tail flicking back and forth as he watched the television screen.
["The Hero Public Safety Commission has issued a formal statement regarding the alarming rise in localized vigilantism," the news anchor reported.]
Footage played on the screen, showing the dark, rain-slicked streets of Musutafu.
["While the HPSC struggles to contain the nationwide outbreak of Trigger-mutated stray animals, an unidentified vigilante duo has been spotted neutralizing threats in the Musutafu district."]
A blurry, grainy cell phone video flashed on the screen.
It showed a massive, two-meter-tall humanoid beast with corded muscles and a cat-like head, standing over a crushed, mutated rat.
Standing right behind the beast was the small silhouette of a kid wearing a dark green hoodie pulled up over his head.
"Oh my goodness," Inko gasped, putting a hand to her cheek. She looked at the television with deep concern. "The world is getting so dangerous lately. Izuku, promise me you will always come straight home after school. Don't linger near the alleyways."
"I promise, Mom," Izuku said, staring down at his bowl of rice to hide his expression.
"Still," Inko sighed softly, looking back at the blurry image of the beast. "I know vigilantism is illegal... but with all these terrible monsters appearing, I can't help but feel grateful. Those selfless people are risking their lives to keep our neighborhood safe. I hope they don't get hurt."
Izuku's heart swelled. He took a bite of his food, a massive, proud smile spreading across his face.
It had been exactly one month since he and Kuro had started patrolling the streets.
They worked in the shadows, using Izuku's tactical mind to hunt down the smaller Trigger-mutated animals before they could hurt any civilians.
Izuku looked over at the sofa.
Kuro met his gaze. The cat didn't meow. He just gave Izuku a slow, intelligent blink of acknowledgment.
"I'm finished, Mom! Thanks for the food!" Izuku said, grabbing his empty plate and setting it in the sink.
He walked over to the sofa, scooped Kuro into his arms, and headed straight for his bedroom.
-----
Click. Thud.
Izuku locked his bedroom door.
He set Kuro down on the center of the rug. The cat sat perfectly still, looking up at him with bright, amber eyes.
Izuku pulled his charred Hero Analysis for the Future notebook from under his mattress.
He flipped past the pages dedicated to All Might, Hero X, and Soot Hero.
He opened the section dedicated entirely to Kuro.
Izuku reviewed the tactical list he had developed over the past month.
[Detective Form: Heightened senses, tracking.]
[Ninja Form: Absolute stealth, wall-crawling, weightless agility.]
[Assassin Form: Lethal speed and blade constructs.]
[Samurai Form: Precision combat and armor.]
[Boxer Form: Hyper-density, unmovable defense.]
[Plus Ultra Form: Absolute brute strength and muscle mass.]
Izuku traced the ink on the page.
The dynamic between him and Kuro was flawless in combat.
Izuku read the battlefield, commanded the specific form, and Kuro executed the physical takedown perfectly.
But as Izuku looked at his own thin, unmuscled arms, a wave of frustration washed over him.
Sigh.
"It isn't enough, Kuro," Izuku whispered, sitting cross-legged on the floor.
Kuro tilted his head, listening intently.
"I don't have a Quirk. I can't change how I was born," Izuku said, gripping his notebook.
"Right now, I'm just hiding in the shadows and giving you orders. If we run into a real villain, and they get past you... I'm dead. If I want to be a true hero, I have to forge my own body. I have to fight alongside you."
Izuku grabbed his pencil.
Scrich-scratch.
He flipped to a blank page.
"Kuro's power isn't just about fighting monsters," Izuku muttered, his mind racing with absolute tactical brilliance.
"Kuro can become any concept I imagine. If I imagine a concept that isn't for combat... but for utility..."
Izuku looked up at the cat.
"Kuro. Let's try something new. I don't want you to fight for me. I want you to teach me," Izuku said.
"Martial Arts Master Form."
Shhh-snap.
The reality around the cat rippled.
Kuro's body elongated, standing up on two legs.
His fur shifted into the shape of a crisp, white martial arts gi tied with a black belt.
He didn't bulk up into a massive beast. He became lean, disciplined, and perfectly balanced.
The new Master Kuro stood in the center of the room.
He raised his paws, dropping into a flawless, traditional defensive stance.
Izuku stood up excitedly. He was a little hesitant, nervous about whether his idea would actually work.
"Wow! You really changed forms!"
He mimicked the stance, raising his own fists. But his posture was a bit crooked.
Master Kuro moved forward.
He gently tapped Izuku's elbow, correcting the angle of his guard.
Then, Kuro swept his leg out, lightly tapping Izuku's ankle to force him to widen his base.
"This is perfect, Kuro," Izuku breathed, his eyes shining with determination. "You can train my body. You can teach me hand-to-hand combat."
"I won't be a liability anymore." Izuku stepped back, lowering his fists.
"But I also need equipment. I need Support Gear to fight Quirk users," Izuku said, his mind moving faster now. "I need someone to teach me engineering and physics, but I can't afford a tutor."
Izuku then stared at Kuro. He formulated the most complex concept he had ever attempted.
"Kuro. Change," Izuku commanded, his voice trembling with excitement. "Academic Scientist Form."
Fwoosh.
The martial arts gi vanished.
Kuro's body shifted again.
He stood upright, slightly taller now. A pristine white lab coat manifested over his fur.
A pair of wire-rimmed reading glasses appeared over his amber eyes. He held a piece of chalk in his paw.
Scientist Kuro adjusted his glasses. He looked at Izuku.
Then, the cat opened his mouth.
"Good evening, Midoriya-kun," Kuro spoke.
His voice was deep, articulate, and carried the refined tone of a university professor.
Izuku dropped his pencil.
His jaw hit the floor.
"You... you can speak?!" Izuku gasped.
"In this conceptual archetype, advanced verbal communication and higher-order academic computation are mandatory," Scientist Kuro explained calmly, pushing his glasses up his snout.
"You require knowledge of mechanical engineering to construct your Support Gear. Where would you like to begin?"
Tears of pure joy pricked the corners of Izuku's eyes.
"Haha! Kuro, you can actually speak! My idea worked!"
He wasn't just a Quirkless kid with a dream anymore. Izuku had a master to train his body. He had a genius to train his mind.
He grabbed a fresh notebook, flipping to a clean page.
"Let's start with kinetic shock absorption," Izuku said, grinning wildly. "I'm going to build myself into a hero, Kuro."
_-_-_-_-_-_
Author's Note:
Hey everyone, hope you enjoyed Chapter 69!
If you are wondering where the inspiration for Izuku and Kuro's unique combat dynamic came from, it is directly based on Xin Ya and Ahu from the donghua To Be Hero X!
Just like in that series, the dynamic relies on a perfect symbiotic partnership. Izuku acts as the ultimate tactician (the brain) who visualizes the concepts, and Kuro acts as the conceptual shapeshifter (the brawn) who physically executes them.
I thought this was the absolute perfect way to give Quirkless Izuku a fighting chance. He doesn't just get a sudden, magical power-up; he has to actually use his biggest strength—his analytical mind and his notebooks—to command Kuro into the exact class or archetype needed for the situation.
Also, just a quick tease for what's brewing in the background: remember that in this timeline, both All Might and All For One are currently operating at their absolute peak. With those two titans playing the board on "Hard Mode," the status quo of the world is changing in a massive way.
