Jinbei, Ahri, Gulleye, Tanjiro, Mangetsu Kenshin, Mingo, and Hachi.
The Warlords (Shichibukai) face off against the Seven Ninja Swordsmen of the Mist.
Amid the chaos of the six-on-six brawl, the fiercest duel was between the user of the Shibuki: Splash, Oniichiro, and the fastest samurai turned pirate, Kenshin,
Oniichiro, brandishing the infamous Shibuki, carved through the battlefield in a storm of detonations.
The weapon was deadly: one edge a normal blade, the other lined with hidden explosive tags that ignited on impact.
Kenshin was on the defensive, weaving through flying rubble and sparks.
He hadn't known about the detonator trick—until Oniichiro slashed, he parried, and the resulting blast nearly tore him in half. Only his swift reflexes saved him.
From there, it became one-sided.
Oniichiro hounded him relentlessly, each strike exploding in a cascade of destruction.
Chasing him down, he laughed. "What's wrong, red-head? Scared to fight me head-on?"
Kenshin's eyes narrowed. "Only amateurs swing for glory. Real samurai... real pirates, don't fear death."
The insult hit a nerve. Oniichiro snarled and lunged for his back—
CLANG!
A whip of chakra steel cracked into his blade, stopping the strike.
"Who the hell—?"
He turned—and there stood Ahri, tails fluttering and a gleam in her golden eyes.
For a moment, Oniichiro was dazed, visions of dancing courtesans in flowing robes filling his sight. Illusion.
Ahri's Genjutsu.
Before he could recover, her twin blades glowed and released gas from their vents.
Chakra surged.
A barrage of light spheres shot from the blades, sizzling through the air.
One sphere whizzed past Ahri, striking the terrain behind Oniichiro.
Yagura's voice boomed from the other end of the battlefield. "Focus, Ahri! Your opponent's me!"
Ahri twirled, smiling seductively. "With a face like this? I'm always forgiven."
Oniichiro shook his head and snapped out of it.
He growled. "Enough! I'm blowing everyone to hell!"
He glanced around.
Kenshin was crouched low, casting a long shadow.
Too late, Oniichiro realized—their shadows were connected.
"Shadow Imitation Jutsu."
Kenshin stood. "Let's end this peacefully—with a bang."
Oniichiro's limbs locked up. "No—wait—what are you doing!?"
He didn't answer.
He was forced to move as she did, sprinting forward.
Straight toward a large figure arguing mid-fight with Hoshigaki Jinbei.
It was the hulking bee-masked flute user, Giantbee.
"Hey! Move!" Oniichiro shouted.
"What the—" Giantbee started.
Too late. Oniichiro dove forward and hugged him.
Giantbee blushed. "Wha—Now's not the time to confess love, man!"
"I lo—" Oniichiro tried to say.
BOOM!
Kenshin had forced him to activate the Shibuki.
A massive explosion rocked the field.
The two of them shot into the air, engulfed in flame.
Mufasa stood watching the flames, arms crossed.
"With a weapon like that, you'd better have an immortal body."
The Mist's numbers dropped from six to four in a flash.
The tide turned. The Warlords quickly overwhelmed the rest of the Swordsmen.
Mufasa raised a hand. "That's enough. No more killing."
He gestured to Mei Terumi's approaching team. "Let her people deal with what's left."
The remaining Swordsmen limped back to their flagship.
Then Obito appeared.
"Whitebeard! You're next!"
Mufasa cocked an eyebrow. "Skipping turns now? You're eager."
Obito sneered. "Screw the rules. Let's finish this war."
"No more games. You're the strongest, right? Then I'm taking you down myself."
Mufasa laughed. "Rules are for the weak. The strong make their own."
Obito nodded, then added, "And yet—you're weak, too."
Mufasa's smile dropped.
"Do you know why I picked you as my opponent?"
Obito said nothing.
"I like arrogant types. The ones with ambition that exceeds their skill. You're the kind I enjoy crushing the most."
That stung.
Obito, the mastermind behind countless conspiracies, clenched his fists.
You're saying I'm all bark, no bite? That my power doesn't match my plans?
"Pompous bastard," he snapped. "I'll break every bone in your body."
Mufasa wiggled a finger. "Such angry words. That makes you sound weak."
Obito froze.
Wait. Aren't you the one acting arrogant right now?
Whatever. He refocused, stepping back to prep a jutsu.
Mufasa mocked him, "Keeping your distance? Afraid I'll vanish if you get too close?"
"There's no need for tactics when there's no match in power. Distance only matters between equals."
He clapped.
"Your defeat was decided the moment you chose to stand before me."
'Hundred Forms: Avalokitesvara!'
Huge chakra surged into the star-shaped ring on Mufasa's hand.
Behind him, an enormous golden chakra-construct began to form—a towering figure with a thousand arms, glowing under the sunlight.
The Hundred-Armed Guardian rose slowly, its radiance stretching across the sea. Even from distant ships, it looked divine.
Terumi Mei stared, stunned.
"What... what the hell is that?!"
Gasps and shouts echoed across the United Navy's ships.
"It's massive!"
"Is that some kind of deity?!"
"A guardian spirit?!"
"Did the gods come down to punish pirates?!"
Mei squinted toward the glowing giant.
No way.
This isn't something the Kazekage could summon casually.
But the sight alone rattled the pirates.
Their cannons fell silent.
The warship guarding the harbor slipped away into the sea.
All signs pointed to the same truth: the pirates were shaken.
From the naval fleet came cheers.
"The gods have answered!"
"This must be divine judgment!"
Some of the younger sailors clapped and cried in joy.
On the island, the pirates, the Three Admirals, and even the Warlords of the Sea stood stunned, staring at the white-bearded titan inside the glowing giant.
Admiration for Whitebeard surged like a tidal wave.
Of course it was their old man.
He stood like a god.
A new world was coming. The era of the Pirate King was upon them.
The pirates screamed in awe and excitement.
From the Land of Water, Daimyo Dōkei nearly fainted.
"That... that thing... that's a monster..."
"Yup. I'd rather choose the guillotine."
"At least it'd be quick."
On Ryugo's flagship, the captured officials and shinobi had fallen into despair.
"We're doomed... the Kingdom of Water is finished."
"This... this is the age of pirates now..."
Nothing they said could change what happened in the sky.
Obito stared at the glowing giant, completely shaken.
But then, he took a breath and calmed himself.
"Tch... So what? You got something big. I got something bigger."
He formed hand seals. "Fire Style: Phoenix Fire Jutsu!"
He exhaled a flurry of small fireballs, like a swarm of fiery birds. They spread in all directions, impossible to dodge entirely. Each ember moved with chakra precision.
It was beautiful and deadly.
Mufasa chuckled.
"You're gonna fight me with this little party trick?"
"Kid, I've trained for decades. You think this impresses me?"
The golden Guardian lifted a single hand.
With a simple sweeping motion, it swatted the flames from the sky.
"Come on. Show me something real. Stop wasting my time with fireworks."
Obito gritted his teeth. His Sharingan flared.
"Fire Style: Gale Flare Tempest!"
He twisted space with Kamui, triggering violent whirlwinds. From his mouth came a spiraling inferno, forming a flaming tornado that shot forward like a dragon.
Wind fed the fire. It roared like a living beast.
Mufasa raised an eyebrow.
"Now that's a little better."
"Hundred-Armed Guardian: First Form!"
One arm lifted high.
It struck down like a falling mountain.
The hand blade collided with the flaming vortex.
In an instant, the fire dragon split down the middle.
The storm scattered.
The flames disappeared.
From the ground below:
"Father is unstoppable!"
"Whitebeard rules!"
The pirates cheered, rallying behind Mufasa.
Obito stared, his jaw clenched.
He could barely believe the power behind that glowing titan.
Mufasa glanced at him. "Come on now. If you don't go harder, this won't even be fun."
Obito: "Fun for who?"
Mufasa scratched his head.
"Well, stepping over an ant without crushing it... takes effort."
"So do me a favor and fight harder. I don't wanna feel bad if I accidentally vaporize you."
BOOM.
A vein popped in Obito's head. Blood rushed upward.
He dared call me an ant?!
Obito snapped.
"No more games."
He roared.
Susanoo: Full Form.
Light surged around him.
A titanic armored warrior emerged—blue as ice, with wings and twin swords.
Obito stood tall atop its crown.
Another mountain-sized giant had entered the fray.
The navy watched in awe.
"Is... is that another god?!"
Terumi Mei whispered, "Who the hell is that?"
Obito's full-body Susanoo stood proud.
From Ryugo's ship, voices rose.
"Luffy! Let's go, brother!"
"Luffy, save the Land of Water!"
The people cheered for their new hope.
To them, Luffy was the spark of a new age.
Among the Shichibukai, concern spread.
Hoshigaki Kisame muttered, "Whitebeard will be fine, right?"
Ganji smirked. "Old man's stronger than he looks."
Mufasa narrowed his eyes, impressed.
"So, the brat had a trump card after all."
Just a little taunt and he went full Susanoo.
Obito stared him down.
"Didn't expect this, huh, old man?"
He pointed both swords down.
"Scared yet?"
Mufasa just grinned.
"What, you think showing up with your fancy armor makes you special?"
Obito twitched.
"You talk too much."
He launched Susanoo forward.
Blades in hand. Slicing through the sky.
Mufasa raised his hands.
"Hundred-Armed Guardian: Third Form!"
Two colossal hands pressed together in prayer.
Clap!
They caught the dual swords mid-swing.
Obito grunted, locking blades.
Mufasa: "You came swinging, now take the consequences."
Fifth Form!
Three of the Guardian's fists reeled back, then rocketed forward.
They slammed into Susanoo.
Obito was sent flying across the sky.
