A year and a half ago…
Sugisawa Yuuto had crossed over into the world of pirates.
Relying on the system's beginner gift pack, he obtained Thunder Dragon Slayer Magic.
As the Fairy Tail guild continued to upgrade, Yuuto's Thunder Dragon Slayer Magic also rose to its absolute peak.
During the Sky Island battle, Yuuto managed to consume the power of the Logia-type Thunder Fruit, thanks to Irene's high-tier blessing.
With that, his thunder-based Dragon Slayer abilities fully sublimated—
and the Thunder Dragon King Mode was awakened.
Not long after the Sky Island incident, Yuuto received Fire Dragon Slayer Magic from a guild upgrade reward.
After relentless training, plus the system's boosts, his Fire Dragon Slayer Magic also reached its maximum level.
However…
Although it had peaked, it had not fully sublimated.
Ordinary Fire Dragon Slayer Magic could not fuse with Thunder Dragon King power.
It could only merge with ordinary lightning—
creating the Thunder-Flame Dragon Mode.
The Thunder-Flame Dragon Mode was far stronger than individual Thunder or Fire Dragon Slayer Magic…
yet it still fell short of a true Dragon King Mode.
Ever since discovering this limitation, Sugisawa Yuuto had been waiting—
yearning for the full sublimation of Fire Dragon Slayer Magic.
And then…
A year ago, during the Wano Country incident, the opportunity finally arrived.
To save Wano, Yuuto successfully consumed the Mera-Mera no Mi.
With that, Flame Dragon King Mode awakened.
However…
Even after unlocking the Flame Dragon King, Yuuto never combined both Dragon King Modes.
Because—
he had no worthy opponent.
Even the Four Emperor Kaido of the Beasts was crushed by one Dragon King Mode alone.
Let alone the combined might of both.
A single Dragon King Mode was already enough for Sugisawa Yuuto to defeat any powerhouse in the sea.
But now…
Here, on this battlefield—
facing two of the world's highest authorities, the Five Elders—
for the first time, Sugisawa Yuuto combined the powers of the Thunder Dragon King and the Flame Dragon King.
Not because the Five Elders themselves were strong enough to force it…
but because this was a threat to the entire World Government.
RUMBLE—!
Blazing golden-red flames erupted into the sky.
CRACK—BOOM!!
Black-red lightning tore open the heavens.
WHOOSH—
Massive elemental dragon wings unfurled behind Sugisawa Yuuto.
On his left—
golden-red flames dancing with streaks of black-red lightning.
On his right—
black-red lightning roaring with arcs of golden-red fire.
Fire and thunder—
the world's two most destructive forces—
merged perfectly inside Yuuto's body.
Thunder Flame Dragon King Mode — ACTIVATED!!!
An unprecedented wave of pressure exploded outward, shaking the entire battlefield.
Everyone still standing felt their bodies tremble uncontrollably.
"Hahahahaha! THAT'S the power of our President!"
Rocks the Overlord grinned wildly, mouth stretching wider in excitement.
"Jie-hahahaha! Subarashii! Truly subarashii! This power is divine!!!"
Golden Lion Shiki cackled with madness.
"This era has shifted—far from the future we once foresaw…
but perhaps that's not such a bad thing."
Pirate King Roger flashed a bold smile.
"That man… still had this much power hidden?"
Marine Hero Garp clenched his fists, frustration and awe mixing on his face.
"Damn it… damn it… DAMN IT! How is that brat even possible…?"
Fegaland Garin, leader of the Knights of God, clutched his bleeding waist, face twisted in despair.
"That bastard… he's even stronger than he was a year ago!"
Kaido's pupils contracted sharply.
He, more than anyone, knew the true terror of Sugisawa Yuuto's strength.
A year ago he was defeated—
but at least he fought a fierce, satisfying battle.
Now—
Here and now—
Feeling the overwhelming pressure of Yuuto's Thunder Flame Dragon King Mode,
the indomitable Kaido felt something he almost never experienced—
fear.
Before this Yuuto, Kaido couldn't summon even the slightest will to resist.
"Give it up, Daddy Minotaur! You'll never beat the President!"
Yamato declared proudly.
"Ku la la la la… Give up, Marines! Give up, World Government!
You cannot defeat that man!
He is the TRUE strongest of this era!"
The Four Emperor Whitebeard roared with laughter.
"Scary~"
Admiral Kizaru pouted lazily.
"Ahh… looks like I really can't win this time."
Admiral Aokiji sighed, shaking his head.
"So after all this… that bastard still had more hidden away?"
Admiral Akainu growled, face twisted as though he'd swallowed a hundred dead flies.
But right now—
The people with the deepest, most visceral reaction to the Thunder Flame Dragon King—
were the two Five Elders standing directly in front of Sugisawa Yuuto.
The ones about to face the storm head-on.
