The rest of the day passed in a strange blur for Kaito.
After the breakfast chaos that ended with his father fleeing the dining room and his mother calmly following him with a smile that promised consequences, the house slowly returned to its usual peaceful rhythm. The sounds of the morning faded into quiet domestic normalcy. Birds chirped outside in the garden. Wind rustled through the trees. Somewhere in the distance a lawn mower hummed faintly from a neighboring house.
But inside Kaito's head, things were anything but calm.
He sat on the wooden veranda facing the garden, small legs dangling slightly above the floor while his mind replayed everything that had happened that morning.
Both his parents had quirks.
The realization alone had been enough to shake him.
His mother's quirk, Featherweight, was gentle and subtle. It was the kind of ability that blended quietly into everyday life, something that most people might overlook if they were not paying attention. But his father's quirk was something entirely different.
Solar Capacitor.
Even now the name echoed in his mind.
A biological solar battery that absorbed sunlight and converted it into energy that could be used in multiple ways. Heat blasts. Electrical output. Radiant light emission. Physical reinforcement.
'That's ridiculous.'
The thought surfaced again as he stared at the garden pond where colorful koi fish drifted lazily through the water.
'That quirk is ridiculously powerful.'
Even with the limitations his father had mentioned, the overall capability was still incredible. A power like that should easily place someone among the higher tiers of professional heroes.
Kaito leaned his chin against the wooden railing.
'So why don't I remember him?'
That question had been bothering him all day.
If Daigo Amamiya was a pro hero with such a versatile quirk, then logically he should appear somewhere in the hero rankings he remembered from the anime.
Yet the name Helios Dynamo did not exist in his memory.
That meant one of two things.
Either his father operated under a lower public profile than most heroes, or the world he was living in was already diverging from the version he remembered.
The second possibility made his stomach tighten slightly.
'Butterfly effect...'
The term floated quietly through his thoughts.
His existence alone was already an anomaly.
A reincarnated individual carrying memories from another world.
Even if he tried to live quietly, his decisions, his actions, his very presence could influence events in ways that the original timeline had never accounted for.
That meant the future he thought he knew might not unfold the same way.
Kaito closed his eyes briefly.
A strange mixture of unease and determination settled inside his chest.
Then another thought surfaced.
Safety.
Right now he was safe.
His father was a pro hero.
Even if Daigo was not among the absolute top heroes like All Might, a quirk like Solar Capacitor combined with professional training meant he was likely ranked fairly high.
Top fifty at least.
Maybe even top thirty.
Kaito could not confirm it yet, but his instincts told him that was probably accurate.
Which meant that for the moment, their family was protected.
But how long would that last?
Heroes fought villains.
Villains fought back.
The world of My Hero Academia was not gentle.
Accidents happened.
Battles escalated.
Entire city blocks could be destroyed during major conflicts.
Kaito slowly clenched his small hands.
He trusted his father.
That was not the problem.
The problem was something else entirely.
Helplessness.
Memories of his previous life surfaced again, uninvited but vivid.
The hospital bed.
The constant weakness in his muscles.
The helpless feeling of being trapped inside a body that refused to cooperate.
He remembered watching the world through screens while other people lived their lives freely.
He remembered the frustration of knowing he could not protect himself.
Could not help anyone.
Could not even stand up without assistance on his worst days.
That helplessness had defined his entire existence.
And the thought of returning to that feeling made something deep inside him recoil.
'I refuse.'
The words formed in his mind with quiet intensity.
'I refuse to be that weak again.'
He opened his eyes.
Sunlight glimmered across the surface of the pond.
The world felt peaceful.
But he knew better now.
Peace could disappear in an instant.
His thoughts drifted briefly toward the heroes he remembered from the anime.
All Might.
The Symbol of Peace.
A man who stood at the top of the world like an unshakable pillar.
Kaito had admired him deeply in his previous life.
Still did, to some extent.
But admiration was not the same as reliance.
'All Might won't always be there.'
The truth was obvious.
Even in the anime timeline, All Might's era eventually ended.
And what came after that?
His mind briefly recalled the next generation.
Izuku Midoriya.
The boy who inherited One For All.
Kaito sighed quietly.
'A naive fanboy with a savior complex.'
Midoriya had a good heart, but relying on someone like that to protect the entire world was a dangerous gamble.
Then there was Katsuki Bakugo.
Powerful.
Explosive.
And incredibly unstable during his early years.
'A complete hot head.'
Kaito shook his head slightly.
Depending on people he barely knew was irresponsible.
Even if they eventually became great heroes, that future was uncertain.
And more importantly, their responsibilities would never revolve around protecting his personal life.
His family.
His home.
His happiness.
That responsibility belonged to him.
He had promised himself something the night before.
Nothing would stop him from living a happy and fulfilling life.
Which meant he needed to start taking action.
Waiting passively was not an option.
He glanced down at his tiny hands again.
Three years old.
His quirk had not awakened yet.
Most children in this world developed their quirks around the age of four.
Which meant he might still have to wait months, maybe even a year.
But waiting did not mean doing nothing.
His parents both had quirks.
Genetically speaking, the chances of him inheriting one were extremely high.
When that moment came, he wanted to be ready.
Which meant he needed a head start.
And there was only one person who could realistically help him with that.
His father.
Kaito slowly stood up.
The decision settled firmly in his chest.
He walked through the quiet hallway toward the living room where he knew Daigo usually spent his afternoons when he was not on duty.
As expected, he found his father sitting on the couch reading something on a tablet.
Daigo looked up when he heard the small footsteps.
"Hey, Kaito."
He smiled casually.
"What's up?"
Kaito stopped a few steps away from him.
His expression was serious.
Very serious.
So serious that Daigo blinked in mild surprise.
"What's that face for?" he asked with a small chuckle.
Kaito took a breath.
Then he spoke.
"Dad."
"Yeah?"
"I want you to train me."
Silence.
Daigo stared at him.
Then he blinked.
Then he laughed.
Not in a mocking way.
Just pure confusion mixed with amusement.
"Train you?"
"Yes."
Daigo rubbed the back of his head.
"Kaito... you're three."
"I know."
"You can barely reach the kitchen counter."
"I know."
Daigo tried very hard not to laugh again.
"Training a three year old doesn't make any sense."
Kaito did not move.
Did not smile.
Did not act embarrassed.
He simply stood there with the same serious expression.
"I don't want to be weak."
The words were quiet.
But the tone behind them made Daigo pause.
Something about the way his son said it did not sound like childish excitement.
It sounded like a decision.
Daigo leaned forward slightly.
"What do you mean?"
Kaito hesitated briefly.
Then he spoke carefully.
"I know my quirk hasn't appeared yet."
Daigo's eyebrows lifted slightly.
"But it probably will."
"Most likely," Daigo admitted.
"And when it does... I want to be ready."
His voice remained steady.
"I don't want to wait."
Daigo studied his son silently.
This was not the kind of conversation he expected to have with a toddler.
Yet something about Kaito's eyes made him listen seriously.
Before he could respond, another voice spoke from the doorway.
"Absolutely not."
Akari stood there with her arms crossed.
Her expression was calm.
But firm.
"Kaito is three years old, Daigo."
She walked closer.
"He should be playing with toys, not training like a hero."
Kaito turned toward her.
"I can do both."
Akari's gaze softened slightly, but her concern remained.
"Training can be dangerous."
"I won't do dangerous things."
She looked at Daigo.
"You see what you're doing? You encouraged this."
Daigo raised his hands defensively.
"I didn't say anything yet."
Akari sighed.
"He is a child."
Kaito looked between his parents quietly.
Then he spoke again.
"I remember what it feels like to be weak."
Both adults froze.
The words were simple.
But something about the way he said them felt heavier than they should.
Daigo felt a strange unease in his chest.
He could not explain why.
But his hero instincts were telling him something important.
This was not a childish whim.
This determination was real.
Ignoring it might actually hurt more than helping it.
He exhaled slowly.
Then he looked at Akari.
"I won't push him."
She remained silent.
"I'll design training that's appropriate for his age."
Still silence.
"He won't get hurt."
Akari studied her son's face.
Then she sighed.
"You promise?"
Daigo nodded.
"I promise."
Another long moment passed.
Finally she stepped back slightly.
"Fine."
She pointed at Daigo.
"But if he gets hurt even once..."
"I know."
She turned toward Kaito.
"And you stop the moment you're tired."
Kaito nodded.
"I will."
The tension in the room slowly faded.
Daigo stood up and stretched slightly.
"Alright then."
He smiled down at his son.
"Let's see what you can do."
The training did not start the way Kaito expected.
There were no intense workouts.
No dramatic combat lessons.
Instead Daigo began with something much simpler.
Games.
Balance drills where Kaito had to walk across narrow wooden boards placed on the ground.
Obstacle courses made from pillows, chairs, and cushions scattered around the living room.
Playful sparring sessions using soft padded gloves.
Running games in the park that slowly pushed his stamina.
Breathing exercises where Daigo taught him how to focus and calm his mind.
At first Kaito felt slightly disappointed.
But that feeling vanished quickly.
Because even these simple exercises were exhausting.
His body was healthy.
But it was still the body of a three year old.
His legs tired quickly.
His arms felt heavy after only a few minutes of activity.
Sometimes he stumbled.
Sometimes he fell.
And sometimes frustration bubbled up inside him when his body refused to keep up with his determination.
But he never quit.
Every time he fell, he stood up again.
Every time he grew tired, he pushed a little further.
Daigo watched all of this carefully.
Behind his relaxed smile, his mind was analyzing everything.
Balance.
Coordination.
Reflexes.
Focus.
He was not building strength yet.
He was building a foundation.
The kind of foundation that every hero needed before they could truly grow.
By the time evening arrived, Kaito felt like his entire body had been drained of energy.
Every muscle ached.
His legs felt like jelly.
His arms barely lifted.
But as he slowly walked back toward his room after dinner, something strange filled his chest.
Satisfaction.
This exhaustion was different from the weakness of his previous life.
That exhaustion had been painful.
Hopeless.
This one felt earned.
He climbed onto his bed and collapsed onto the mattress.
His body immediately relaxed into the soft blankets.
His eyes slowly closed.
'This is only the beginning.'
The thought drifted quietly through his mind.
Somewhere deep inside his body, something stirred.
Faint.
Subtle.
Almost unnoticeable.
But real.
A quiet spark waiting for the right moment to ignite.
And as Kaito fell asleep, unaware of the change slowly unfolding within him, the first step of his new journey had already begun.
