Kaito did not remember walking to his room.
One moment he had been sitting in front of the television, staring at the impossible figure of All Might smiling triumphantly through the smoke and chaos.
The next moment he was standing in the middle of his room with the door closed behind him.
His small chest rose and fell rapidly.
The television's distant sound echoed faintly from the living room. Reporters were still talking, voices full of excitement and relief. People were cheering. His mother occasionally reacted with soft amazement at the broadcast.
But Kaito barely heard any of it.
His mind was spiraling.
He slowly sat down on the tatami floor. The room felt different now. Not physically different, nothing about the walls, the sunlight, or the quiet comfort of the house had changed. Yet mentally it felt like everything had shifted.
Before today it had been the room of a child blessed with a miraculous second life, a peaceful place filled with toys, soft blankets, sunlight, and the quiet comfort of loving parents. Now it felt like the center of a storm, a place where reality had finally caught up with him.
He placed his small hands on the floor and stared at them.
Tiny fingers.
Soft skin.
No IV scars.
No trembling.
Healthy.
Alive.
And now possibly in danger.
He inhaled slowly, trying to steady himself, then exhaled.
"Okay..."
His childish voice sounded small in the quiet room. The word echoed faintly against the wooden walls.
He rubbed his face with both hands.
The gesture looked oddly adult on someone who barely reached the height of a small table.
This was bad.
Not bad because something terrible had happened to him. In fact the exact opposite had happened. Something miraculous had happened to him. He had died and then he had been reborn. A second life. A healthy body. Loving parents. A comfortable home.
For days he had simply accepted it.
Enjoyed it.
Celebrated it.
He had run around the house like an excited child discovering the world for the first time. He had played with toys, eaten food that did not taste like hospital meals, and slept in a bed that was not surrounded by machines. He had laughed, genuinely laughed, without the constant weight of sickness hanging over him.
But he had not asked questions.
Not the important ones.
His small fingers curled slightly against the tatami.
"I got complacent..."
The words came out slowly, thoughtful and quiet. His voice carried a strange mixture of innocence and maturity. Not quite the voice of a child, but not fully the voice of the nineteen year old he once was either.
His mind existed somewhere between the two.
The excitement of a child discovering life.
The reasoning of someone who had already lived one.
And now both sides were realizing the same thing.
He had made a mistake.
A big one.
He had accepted his new life as a miracle and stopped thinking about everything else.
Why did this happen?
How did this happen?
Why him?
The questions felt heavier now.
Before seeing All Might on the television they had been distant curiosities. Interesting thoughts that occasionally floated through his mind before drifting away again.
Now they were serious.
Very serious.
He swallowed and looked toward the small desk near his bed. After a moment he stood up and walked over to it, grabbing a small notebook that had originally been meant for childish drawings.
Right now it was going to serve a different purpose.
He sat down again and picked up a crayon.
The act felt almost ridiculous.
A three year old sitting cross legged on the floor, frowning seriously while holding a crayon like a researcher preparing an important report.
Yet it helped him think.
He slowly began drawing a line across the page, marking the beginning of a rough timeline of events.
The first point was simple.
He died.
The crayon paused slightly as memories returned. The hospital room, the constant beeping of machines, the faint smell of antiseptic that had followed him his entire life. His mother's trembling hand holding his, his father's quiet voice trying to stay strong even when the doctors had clearly run out of answers.
And the peaceful darkness that had followed.
His chest tightened for a moment but he quickly blinked the feeling away. That life was over. It had ended quietly and gently.
The next point came easily.
He woke up.
But not in a hospital room, not in a place filled with machines and doctors. He had opened his eyes in the body of a small child.
Three years old.
Kaito Amamiya.
The name looked slightly clumsy written in crayon, yet it still felt real. That was his name now.
His new identity.
The following realization had come soon after.
A new family.
His mother, Akari Amamiya, a warm and gentle woman who always seemed to smile with her eyes. His father, Daigo Amamiya, calm and confident with the quiet patience of someone used to responsibility.
And most importantly he was their only child.
That fact had become obvious quickly. The house had no other children's voices echoing through the halls. No toys scattered around belonging to anyone else. No siblings to argue or play with.
Just him.
And his parents.
A faint smile appeared on his face as he thought about them. They were good parents. Very good parents. His mother was attentive and affectionate, always checking on him, always ready with a warm meal or a gentle hug. His father had a calm presence that made the entire house feel stable.
They loved him.
That much was obvious.
The thought warmed his chest.
But then his mind moved to the next realization.
His body.
Healthy.
That single word still felt unbelievable.
He could run without coughing. Jump without feeling dizzy. Climb furniture, spin in circles, and laugh without the world turning dark around him.
Even breathing deeply felt incredible.
In his previous life every movement had been a careful calculation, every action limited by fragile lungs and failing muscles. Now his body felt like an engine filled with limitless energy.
He looked down at his small arms again and flexed them slightly.
Still amazing.
But that was when his thoughts shifted toward the clues he had ignored.
The first memory appeared clearly.
The neighbor's dog.
He remembered watching the small brown animal playing in the yard when suddenly it had floated slightly above the ground for a few seconds before dropping back down like nothing had happened.
At the time he had blinked in mild surprise.
Then shrugged.
Maybe he had imagined it.
Now the memory felt painfully obvious.
Another clue surfaced.
Conversations.
Neighbors talking casually about quirks.
People mentioning heroes during normal everyday discussions.
Words that should have triggered instant recognition in his mind.
But they had not.
He had been too distracted by the excitement of living again.
Too focused on enjoying simple things like running, eating, and sleeping comfortably.
He sighed quietly.
"Idiot..."
It was not self hatred.
Just frustrated embarrassment.
Then came another memory.
The city name.
Musutafu.
The reporter had mentioned it earlier on the news broadcast.
The moment he heard it his brain had connected the dots immediately.
But thinking back now he realized that he had heard the name before, mentioned casually by his parents during conversations.
And again he had ignored it.
He leaned back slightly against the wall, staring at the notebook resting on his lap.
"So many clues..."
Every realization felt like a missed alarm.
The truth had been right in front of him the entire time and he had been too relaxed to notice.
The realization made his stomach feel slightly heavy.
But another thought followed quickly.
This world was real.
Not an anime.
Not a story.
The world of My Hero Academia existed around him.
But it was also different from the version he had watched.
Anime simplified things.
It focused on heroes and villains, dramatic battles, emotional speeches, and big events.
But real life was more complicated.
There were laws, politics, economics, normal jobs, ordinary civilians trying to live their lives in a world filled with superpowers.
The anime had never shown most of that.
He tapped the crayon lightly against the notebook.
"I don't actually know this world..."
Yes he knew the major story events.
He knew the famous heroes.
He knew the dangerous villains.
He remembered the big battles that shaped the series.
But what about everything else?
How did normal citizens live?
What laws regulated quirks?
How often did villain attacks actually happen?
How did society function on a daily basis?
The questions multiplied rapidly.
He rubbed his temples, which looked slightly strange considering how tiny his body was.
"If I assume the anime is completely accurate..."
He paused.
"...I could die."
The thought settled heavily in his chest.
This world was not safe.
Superpowers existed here.
Which meant destruction existed.
Villains existed.
Cities could be attacked.
People could get caught in the middle of battles they had nothing to do with.
And he was just a child.
A very small child.
The seriousness of the situation finally settled in his mind completely.
Not panic.
But reality.
His expression slowly became more focused.
More determined.
"If I'm going to live here..."
He glanced around the room again, taking in the comfortable surroundings with new awareness.
"...I need information."
Information meant survival.
Understanding meant preparation.
His thoughts shifted toward his family again.
One detail in particular stood out.
His father.
Daigo Amamiya was not home very often during the day.
Sometimes he was gone for long hours.
Occasionally he returned late in the evening looking tired but satisfied.
Kaito had noticed it before but dismissed it as normal work.
Now the observation felt more important.
"What does Dad actually do..."
The realization surprised him slightly.
He did not know.
Not really.
His father sometimes left wearing formal suits, looking like a businessman.
Other times he left wearing casual clothing.
Occasionally he returned with small scratches or bruises, nothing serious but noticeable.
Could he be a hero?
The possibility made Kaito's eyes widen slightly before he shook his head.
No evidence.
Jumping to conclusions would be dangerous.
Still, the question remained.
Another observation followed naturally.
Their wealth.
Kaito slowly looked around his room again.
Tatami floors.
Polished wooden walls.
Sliding paper doors.
Everything was well maintained and carefully designed.
And the house itself was enormous.
When he first woke up he had explored it with childish curiosity.
Now he reconsidered those memories carefully.
Multiple hallways.
Several guest rooms.
A garden large enough to resemble a small park.
Storage areas, study rooms, and quiet corners throughout the building.
He had counted at least ten bedrooms.
Possibly more.
The house could easily hold eight or ten families.
Yet only three people lived here.
Him.
His mother.
His father.
They were clearly wealthy.
Not the kind of wealth that came with massive mansions and private security.
But definitely well off.
The neighborhood itself was quiet and isolated, filled with similar large homes and peaceful streets.
That meant resources.
Opportunities.
Better education.
Better safety.
But it also raised more questions.
How exactly did his father earn enough money to maintain this lifestyle?
Tech industry?
Hero support equipment?
Private business?
Something else entirely?
Too many unknowns.
Kaito leaned back again and stared at the ceiling for a few moments.
His emotions felt complicated.
Excitement.
Fear.
Curiosity.
Determination.
All of them mixing together.
Part of him still felt the childish wonder of a boy who had been reborn in a world filled with heroes and superpowers.
But another part understood the dangers that came with that world.
Heroes fought villains.
Villains destroyed cities.
Innocent people often got caught in the middle.
If he wanted to live a long life here, he could not afford to remain ignorant.
His expression slowly hardened, not in anger but in quiet determination.
He looked down at his tiny hands again.
A three year old.
But carrying the memories of nineteen years.
That gave him an advantage.
Not perfect knowledge.
But experience.
Patience.
Perspective.
He slowly closed the notebook.
"I want to live."
The words were quiet but sincere.
In his previous life he had barely lived at all. Hospitals, pain, and limitations had defined almost everything.
Now he had been given a second chance.
A real chance.
To run.
To laugh.
To grow.
To build friendships.
To experience the world properly.
And he refused to waste it.
His small face slowly became serious, unusually serious for someone his age.
"If this world is dangerous..."
Then he would learn how to navigate it.
If quirks existed, he needed to understand them.
If heroes and villains shaped society, he needed to understand their roles.
If there were risks to ordinary civilians, he needed to know how to avoid them.
Knowledge would be his first weapon.
Then planning.
His determination grew stronger as he thought about his parents again.
His mother's gentle smile.
His father's steady voice.
Warmth spread through his chest.
He already cared about them deeply.
They were his family now.
And he wanted to protect the happiness he had found with them.
"I want to live a good life."
A normal life.
A happy life.
Maybe he would never become a hero.
Maybe he would simply live quietly.
But whatever path his life took, he would fight for it.
His tiny fists slowly clenched.
With a seriousness that did not belong on the face of a three year old.
But also with a quiet hope that did.
"No one..."
he whispered softly.
"Nothing..."
His gaze shifted toward the window where sunlight poured gently into the room.
"...is going to stop me."
He took a slow breath.
The first step was simple.
Learn.
Observe.
Understand.
This world.
Its rules.
Its dangers.
Its opportunities.
Because if he truly existed in a world filled with heroes and villains...
Then surviving here required more than luck.
And Kaito Amamiya intended to survive.
More than that.
He intended to live.
Fully.
Freely.
And happily.
For as long as this second life would allow.
