Tokyo.
Rain slid down the glass like the world itself was dissolving.
Kaiser did not remember when he stopped feeling tired.
It had passed beyond exhaustion.
Beyond pain.
Beyond stress.
There was only numbness.
The clock on the office wall read 2:47 AM.
Again.
The fluorescent lights hummed.
He was the only one left in the department.
Three monitors glowed before him.
Spreadsheets.
Forecast models.
Emails marked "URGENT."
His phone buzzed.
Manager:
"Need revision before 7 AM. Client unhappy."
Kaiser stared at the message.
He had already redone that report five times.
His fingers hovered over the keyboard.
He whispered quietly:
"…I haven't seen the sky in days."
He couldn't remember the last time he spoke to someone without a deadline attached.
No lover.
No friends.
Parents aging back in Osaka.
He sent money.
That was it.
A hollow existence wrapped in responsibility.
His heart thudded strangely.
Once.
Twice.
Then—
Pain exploded in his chest.
His breath caught.
The world tilted.
He tried to stand.
His legs refused.
The desk came rushing toward him.
Darkness swallowed everything.
He died without anyone noticing.
Silence.
Then—
A voice.
Cold. Mechanical. Vast.
"Soul identified."
"Willpower exceeds threshold."
"Desire detected: Freedom. Strength. Authority."
"Reincarnation compatibility confirmed."
Kaiser drifted in nothingness.
"…Reincarnation?"
Fragments of fantasy novels surfaced in his fading mind.
He laughed weakly.
"If there is another life… let me live for myself."
A pause.
Then—
"Request acknowledged."
Light exploded.
Birth Beneath Crimson Skies
Heat.
The scent of earth and trees.
A distant roar of monsters.
Kaiser inhaled sharply.
His body was small.
He felt fabric.
Warm arms cradled him.
A woman's voice trembled with happiness.
"Raizen… he's strong. Look at his eyes."
A deep masculine voice replied.
"Our son… Kaiser."
Kaiser blinked.
His vision was blurry but slowly sharpening.
He saw red skin.
Small horns.
Black hair.
Golden eyes reflected in his father's gaze.
Oni.
He wasn't human.
Memory from novels he once read stirred.
The Forest of Jura.
Monsters.
Magicules.
Demon Lords.
And then—
A translucent blue window appeared before his infant eyes.

His infant heart pounded.
Whitebeard?
Shadow Monarch?
He nearly laughed.
Instead, a tiny squeak escaped his baby throat.
His mother smiled.
"He already has spirit."
Raizen gently placed a large hand over Kaiser's head.
"Grow strong. But grow kind."
The warmth in his father's voice struck him.
This was different.
Not a broken family.
Not cold distance.
Warmth.
He silently vowed:
"I won't waste this life."
Royal Oni Clan
The Royal Oni were not common monsters.
They were a proud, ancient bloodline residing deep within the central Jura forest.
Stronger than ogres.
More disciplined than orcs.
Respected by lizardmen.
Avoided by lesser tribes.
Their village was built into enormous crimson trees.
Bridges of wood and bone connected platforms.
Training grounds lay at the center.
Children learned swordsmanship early.
Unity was their law.
Strength protected family.
Family protected tribe.
And Kaiser was born as the second child of Chief Raizen.
His Siblings
Shiori — his older sister.
Five years older.
Flame affinity.
Short crimson hair.
Sharp eyes.
Protective to a fault.
She was the first to glare at anyone who teased baby Kaiser.
"If you make him cry I'll burn your eyebrows off."
Even at six years old, she meant it.
Daiki — younger brother.
Born two years after Kaiser.
Wind affinity.
Bright smile.
He adored Kaiser.
Followed him everywhere once he learned to walk.
"Big brother is the strongest!"
Kaiser felt something unfamiliar each time Daiki grabbed his hand.
Warmth.
Responsibility.
This was not the lonely life he had before.
This was family.
And he would protect it.
First Tremor
Age: 3
Oni matured faster than humans.
Kaiser stood in the training ground holding a wooden blade.
Shiori crossed arms.
"Don't cry."
He gave her a calm look.
"I won't."
He swung.
Not with childish recklessness.
But precision.
The moment the wooden sword cut through air—
Something inside him answered.
A pulse.
A vibration.
The ground beneath the training field cracked.
A shockwave erupted outward.
Dust rose.
Nearby warriors stumbled.
Birds exploded from trees in panic.
Silence fell.
Raizen's eyes widened.
"That was not elemental magic…"
Kaiser stared at his small hand.
He felt it clearly now.
A pressure beneath the world.
Like reality itself was fragile glass.
Whitebeard's power.
Even at 10%… it shook the forest.
He inhaled slowly.
Good.
He was not weak.
Night Conversation
That evening, Raizen sat beside him outside their home.
Moonlight filtered through massive tree branches.
"You frightened the elders today," his father said calmly.
Kaiser lowered his head slightly.
"…Was it wrong?"
Raizen chuckled.
"Power is never wrong. But how you use it decides everything."
He studied his son carefully.
"You are different from other children."
Kaiser met his gaze.
In those golden eyes was not childish confusion.
But calculation.
Raizen noticed.
And smiled softly.
"If you carry something heavy inside… you can speak to me."
For a moment—
Kaiser almost told him.
About Earth.
About death.
About second chances.
But instead he simply said:
"I want to protect everyone."
Raizen placed a hand on his head.
"Then become strong enough that no one dares threaten us."
That night, Kaiser made his first true decision.
He would not simply survive in this world.
He would rule it.
Not out of greed.
But to ensure his family would never face extinction.
He had read enough stories.
The Royal Oni were fated to be slaughtered in the future.
By orcs.
By politics.
By Demon Lord schemes.
Not in this timeline.
Not while he breathed.
System Notification
Late that night—
[Gacha Ticket – Beginner Tier Available]
Kaiser's eyes sharpened.
Finally.
He activated it silently.
The world around him froze.
A massive wheel of countless anime worlds spun before him.
Naruto.Bleach.Attack on Titan.Fate.Dragon Ball.Hunter x Hunter.
The wheel slowed.
Stopped.
Golden light burst.
[Obtained: Observation Haki – Beginner]
Kaiser's perception exploded outward.
He felt life signatures.
Magicule density.
Emotional fluctuations.
His sister asleep nearby.
His father patrolling.
Predatory beasts miles away.
He exhaled slowly.
This…
This was absurdly broken.
A smile formed.
Jura would change.
The forest would unite.
And one day—
When a certain blue slime reincarnated—
He would not find chaos.
He would find an empire.
