In this world, every human is born with one of five powers:
Fire.Water.Wind.Earth.Or Lightning.
Unless… you carry royal blood.
Those born into royal families often awaken rare and unique abilities—powers far beyond the standard five.
All except one bloodline.
The Yamazaki bloodline.
Isao Yamazaki, grandson of the legendary Yuto Yamazaki, was born with lightning power—just like his mother, Hope Yamazaki, the current leader of Hishe.
In the modern era, powers had evolved. With enough training, abilities could transform into stronger forms.
Lightning could turn blue.Wind could become a whirlwind.Fire could burn hotter than ever before.
And today…
Was the day it all began for Isao.
sao stretched as he stepped out of bed, rubbing his eyes before heading downstairs.
The smell of food hit him first.
He froze.
Isao: "Mom…? You're home?"
Hope stood in the kitchen, smiling softly.
She was rarely ever home, always busy leading the country.
Hope: "Of course. It's your big day, isn't it?"
Isao smiled.
Hope: "The entrance exam… I'll be rooting for you."
Isao: "Thank you, Mom! I can't believe I got invited… I'm going to become a knight. I'll make you proud."
He paused for a moment.
"…It's what Grandpa would've wanted."
Hope's expression softened, but she didn't respond.
She didn't need to.
The Knight Entrance Exam.
Only the strongest children—age twelve or younger—were invited.
They would fight.
And based on their performance… they would be assigned teams and begin their path as knights.
Outside, Isao met up with his best friend.
Tatsuki Jinno.
Or as everyone called him—
TJ.
Isao (grinning): "You ready to show them what we've got?"
TJ: "Of course. We're going to crush this."
They started walking together toward the arena.
Isao: "I wonder how strong everyone else is…"
TJ smirked.
TJ: "You didn't hear? Endou's supposed to be here."
Isao stopped.
Isao: "No way… the guy who can already use whirlwind power?"
Whirlwind power—an advanced form of wind.
Something most people couldn't achieve for years.
TJ: "Yeah. Honestly… I hope I don't have to fight him."
The arena came into view.
Massive.
Intimidating.
Isao: "Woah… this place is huge."
TJ: "Let's go."
Inside, fifteen other kids had already gathered.
Four sections divided the building.
The air was tense.
A voice echoed through the room.
Proctor: "HELLO!"
Everyone turned.
A tall man stood at the front.
Proctor: "My name is Sawatogi. I'll be your proctor today."
He scanned the group.
"You will be split into four sections. Each section will fight in a bracket to determine your ranking."
He pointed.
"You four—come with me."
Isao and TJ were among them.
As they followed the proctor, Isao spoke quietly.
Isao: "We might end up fighting each other…"
His voice dropped.
"…We won't be on the same team."
TJ smiled.
TJ: "Hey, it's fine. We'll both become knights anyway."
He held out a fist.
"Just don't hold back."
They entered the arena.
A massive battle stage stretched out before them.
Proctor: "First match—Jinno vs Yamazaki!"
Isao froze.
Isao: "…You've got to be kidding me."
TJ laughed.
TJ (whispering): "Sorry. I'm not going easy."
Isao: "Wouldn't expect you to."
They stepped onto the battlefield.
Facing each other.
Best friends.
Now opponents.
Proctor: "Begin when ready."
TJ: "I'm ready!"
Isao hesitated.
Isao: "…No hard feelings?"
TJ: "None."
Isao took a breath.
Isao: "Alright… I'm ready."
Proctor: "Begin!"
TJ rushed forward first—throwing a punch.
Isao blocked easily.
The two clashed in hand-to-hand combat.
Blow after blow.
They were evenly matched.
TJ: "Come on, Isao! Show me what you've got!"
He grinned.
"You're the grandson of a legend, right?!"
Isao smiled back…
But his hands trembled.
Living up to the Yamazaki name wasn't easy.
Isao: "…Alright. You asked for it."
"Lightning Power: Quick Flash!"
CRACK!
Isao vanished.
In an instant, he appeared behind TJ—
BAM!
A kick slammed into TJ's ribs, sending him flying.
TJ hit the ground hard.
But he stood back up.
The other kids watched in shock.
TJ: "Fire Power: Fire Bullet!"
A blazing orb shot toward Isao.
Isao dodged—but the heat still hit him.
Isao: "Not bad."
TJ: "Yeah… too bad it didn't work!"
TJ rushed again.
TJ: "Fire Power: High Spinning Kick!"
His leg ignited as he swung toward Isao's head—
Isao caught it.
Isao: "Sorry… you lost."
"Lightning Power: High Volt Shock!"
Electricity surged through TJ's body.
TJ: "AAAAHHH!!"
He collapsed.
But slowly…
He stood again.
Isao's eyes widened.
That determination…
That refusal to quit…
It's what he admired most about TJ.
TJ: "Fire Power: Fire Clap!"
He slammed his hands together.
Flames exploded across the arena, surging toward Isao.
Isao: "I respect your determination…"
He stepped forward.
"…But I won't lose."
"Lightning Power: Lightning Dragon!"
Lightning erupted around him.
A dragon of pure electricity formed and surged forward.
In a flash—
Isao disappeared from the flames.
Proctor (shocked): "That technique…!"
"Is that… the original Yamazaki move?!"
Isao: "Lightning Power: Quick Flash."
He reappeared behind TJ one final time.
BAM!
TJ dropped.
Unconscious.
Silence filled the arena.
Proctor: "…Winner: Yamazaki."
"Medics—take Jinno."
As TJ was carried away, Isao looked down.
He felt…
Guilty.
But also—
Excited.
His first win.
Proctor: "Next match!"
"Ito vs Sasaki!"
