Now that Bach had been taken out, the remaining Rainbow Fog inside the Iron Paradise had disappeared.
Sin checked one last time to see if there were any survivors, and was relieved to find the island empty.
"Kuma. Go away," he said to the massive man who was sitting on top of the balcony, exhausted, watching Kizaru and Aokiji fighting in the distance with Ragnus. "Go," he said firmly, and the Warlord slammed his right paw on his own chest and disappeared with a pop.
Sin's body swayed as he rested his back against a metallic pillar.
He turned to the side when Garp, leaking blood from his mouth, pushed the rubble away and stood up, panting heavily.
The Marine Hero looked his way and then glanced at Mihawk, who had appeared on top of the roof not far away.
"Can you fight in this state?" The Greatest Swordsman in the World glanced at him, and the Black sighed at his words.
"Rumble..." he whispered, and soon a pillar of lightning fell from the sky, bathing him in it for a minute.
When it ended, there was no longer any lightning in the sky, and rain started pouring heavily on the Iron Paradise.
"Neat," Mihawk smirked when he sensed Sin's improved condition. Not perfect, but improved.
"Thanks," the Black smiled his way and then met Garp's eyes again.
Without a word, the three of them rushed forward, but Ragnus did not want to wait and attacked the Marine Hero, who blocked his sword with his fist, and just when the Warmonger was about to kick him away, having overpowered him, he was forced to change his plan and kick Sin instead.
The Black grunted as he blocked the kick that rattled him, but he did not back down, and the storm that the clash of three Conqueror's Haki brewed split the sky and cleared it in a matter of seconds.
"Galaxy... Divide!!!"
Garp, somehow, managed to punch Ragnus away with his other fist, generating a shockwave that destroyed everything around them and in the Warmonger's trail.
Sin's heart trembled at the display of strength, but there was no time to dwell in fascination.
He rushed forward and pulled the Seven Star Sword from his back, intercepting Ragnus, intending to hack him into two.
To his amazement, the Warmonger managed to react and blocked his sword with the massive sabre he was wielding, and instantly overpowered him.
Just when he was about to be shot away, Sin pulled to the side, leaving Ragnus open to Mihawk's attack, which was splitting the island.
It struck him head-on, and Ragnus was pushed dozens of metres away before he powered through it and rushed at Kuzan, who was preparing for an attack.
Garp blocked the sword with his fist again, but suddenly, a metallic spike, imbued with Armament and infused with Conqueror's Haki, erupted from under his feet.
At the very last moment, Sin kicked the Marine Hero to the side, and the spike only managed to land a cut across his chest instead of piercing him.
The Black, however, was left at the mercy of the sabre that descended on him, which he had to block now.
He stared into the blue eyes of Ragnus, who was madly grinning, and that ring around his pupils made him grit his teeth.
Now he knew why Garp was suffering so much. The old man's Haki was not what it once used to be, and against Ragnus's Future Sight, he was at a disadvantage.
It was still a marvellous feat that he had managed to hold back this monster of a man for so long.
"I want your blood, brat."
Despite the situation, Sin managed to smile at Ragnus's words, and just when it looked like the sabre would get past his sword, a terrifying burst of Conqueror's Haki erupted from his body.
"You see, old man, I don't like losing," he said coldly, and the Seven Star Sword gleamed.
The two Colours of Supreme King's Haki clashed, and even though Sin was unable to push the enemy away, he was not backing down either.
Only Mihawk managed to recover from his shock in time, and he sent out another island-splitting attack at the Warmonger, which forced him back by the sheer momentum of it.
Sin leaned forward, waited for Mihawk's attack to pass by, and then charged forward at a speed that baffled the enemy.
"God's Blade!" He infused the Conqueror's Haki to its limits inside the sword, intending to cut Ragnus into two, and even though his attack was blocked, the residual power split up and landed on his torso.
Kuzan gaped when he saw Ragnus being sent flying, crashing into a metallic cube in the distance.
He narrowed his eyes at the diagonal gash that was left on the Warmonger's torso, which was bleeding, and it was deep enough that he saw the man groaning in pain.
Sin furrowed his brows as he panted, not happy that he had failed to cut the enemy into two.
"Jahahahahahahaha...."
All of their hearts skipped a beat when Ragnus manically started laughing, and then he jumped out of the metallic cube and laughed even louder.
Suddenly, the metallic surface under their feet started turning into liquid, and the Warmonger's body turned shiny silver as well, almost as if he were made out of mercury.
His body started growing larger and larger, and before they knew it, he had turned into a titan of metal.
The entire Iron Paradise suddenly started liquefying, and just when they thought of escaping, Ragnus blocked the sky above them with a metallic wave that soon encompassed the entire island.
"Awakened Logia..." Kizaru had never sounded so solemn in his entire life, and before they knew it, none of them could stand on the ground that tried to trap them.
Within seconds, their entire world had turned dark, and only after Kizaru illuminated his body were they able to see again, and then something terrifying happened.
The massive sphere they were now caged inside started filling up with seawater.
"Oi!" Kizaru shouted at his fellow Admiral, snapping him out of the trance, and Aokiji immediately used his ice powers to freeze the inlets.
However, he noticed that Sin's face was turning more and more grim.
"What's going on?"
"He's sinking us to the bottom of the sea."
"Oi, oi..."
"This is troublesome-ne..."
Sin glanced at Aokiji, his eyes flickering with lightning, and he could see that the Admiral was far too tired to get them out of there.
Seconds later, more inlets appeared in the sphere, even from above, and he gritted his teeth.
"He will go after the others..."
His words turned Garp's eyes very cold.
"So, what are you going to do now?" Mihawk lightly smiled and asked.
"Can you cut the sea?" he asked back, and the Greatest Swordsman in the World smiled, which made him smile too. "Nah, save your strength. You and the old man are on your own."
At his words, the two Admirals curiously looked at him.
"Grab the Iceman and stay in my trail, and be very careful," he warned before his body started shining.
Within seconds, they were all sweating, and their skin started burning.
Transforming into Plasmic Spirit, Sin glanced at Kizaru and nodded his head.
Betting his life on the line, the Lightman grabbed Aokiji, and the moment Sin shot up, he chased, trying to stay in his trail.
They were dismayed at how he pierced through the seawater, which turned into plasma on contact with his body.
However, they felt like they would burn to death, especially Kuzan, and just when even his Haki started failing, they managed to shoot out of the sea.
The Iceman quickly created a small ice platform for himself, and Kizaru created two Light Clones, who immediately grabbed Garp and Mihawk when they jumped out of the sea.
Without wasting any time, they rushed after Ragnus, who had created a metallic road and was about to attack the retreating Marines.
What they and everyone else witnessed next would forever remain preserved in their memories.
A shooting star pierced right through the body of the Metal Titan again and again, at an unreal speed, crumbling it down, stopping it, and then retreated.
Garp and Kizaru managed to intercept Ragnus in time when he was about to attack Sin, who had suddenly returned to his normal form and was dropping on Tsuru's ship.
Mihawk joined them only a moment later and pushed the Warmonger back.
Yamato, who was onboard, jumped up and grabbed Sin, having transformed into her Hybrid Zoan Form, and at the same time, she shot a blast of ice from her mouth, which froze the raining metallic bullets in the sky.
As soon as her feet touched the ship, the shockwaves pushed the vessels away, and she saw how Mihawk and Kizaru had blocked the massive sabre, and how the old Marine Hero smacked a fist across Ragnus's face, sending him shooting into the sky.
Her eyes sparkled at the show of power and the Colours of Supreme Kings that were emanating from the Marine Hero and the Greatest Swordsman in the World.
"Don't think about it."
She pouted when she heard Sin's words, but then worriedly looked at him.
His face was pale, and he seemed out of strength.
"Wake me when you sense that they cannot hold on any longer..." he whispered before falling asleep in her lap, and she solemnly stared at the fighting in the distance that was now taking place on top of the Rainbow Icebergs that Robin had created earlier.
