One piece: Into the new world.

As the cannonballs struck the ground, multiple explosions rang out as the surrounding environment was destroyed, the trees and bushes were destroyed.

Soon a fire was lit and a burning inferno swept the island ablaze.

Having transformed back into his human form earlier, he quickly utilized his Bisento, and slashed all the incoming cannonballs stopping the island from further harm.

*Slash*

With a single swing, dozens of cannonballs in a row were sliced cleanly in half and exploded mid air, blocking the marines view with a smokescreen.

{on the marine ship}

"DAMN IT, WHO IS THAT BRAT."

A man wearing a Vice Admirals coat shouted loudly. Veins popped on his face, as he bit the cigar in his mouth, crushing it.

"KUZAN, DEAL WITH THAT BRAT"

The man in question was laying down on the deck, looking around lazily. 

"huh, what brat."

He then looked off into the distance and saw the person in question slicing cannonballs like butter.

"Oh alright, if you say so. Ill deal with him."

He stood up slowly and walked to the edge of the ship, before walking straight off and falling onto the surface of the water. 

The surface water quickly froze over and was strong enough to hold him.

He walked over slowly to the man cutting cannonballs and stood in front of him.

The marines shooting cannonballs didn't dare shoot as their superior was standing in the direct path.

"Hey brat, what do you think your doing?"

{Back to our Chad}

"Hey brat, what do you think your doing?"

Hearing the man who he would least like to see, he wanted to leave an impression on him and speak the truth.

"I'm protecting innocent people who were sentenced to death."

Although Aokiji remained silent, Kurihana could see the conflict on his face, showing he was still not alright with all the slaughter of these innocent people.

"Step aside, I'll let you go if you swear not to interfere on official Marine business."

"I'm sorry, but I can't do that. Your Marine business is not worthy of being called Justice. It's glorified murder, and you know it. If you still want me to move, you'll have to make me."

Getting into position to fight, he brandished his Bisento ready to clash with the Ice Man.

Aokiji didn't say anything, but he started the fight with a wave of his hand as the air in front of him froze and ice spikes tried to stab him.

He quickly swung his Bisento in a wide arc and destroyed all the ice, as he dashed forward and stabbed Aokiji in the gut.

The blade went a foot in before Kurihana pulled out and started slashing him in all his vital areas.

Aokiji stood there as the blade did nothing to damage him.

Seeing nothing was happening, Kurihana stuck his Bisento into the ground and transformed into his Vermillion Bird form.

Aokiji was shocked to see him transform into a giant flaming bird. From the little information he saw he could instantly assume this was a Mythical Zoan fruit.

Kurihana instantly jumped into the air and dive bombed Aokiji spewing his undying flame, because he was surprised. This attack managed to hit Aokiji. 

Getting hit by the undying flame, naturally Aokiji tried to put it out, but no matter what he did it wouldn't go out.

Seeing it was pointless, Aokiji tried to regrow replace his outer layer of skin with ice and then shed it. But the flame followed him like it was sentient.

While Aokiji was distracted with trying to put out the flame, Kurihana was preparing a powerful attack that would either be useless or end the fight.

The attack was finally ready and as he launched it, flames the shape of an undying phoenix took form and flew in the air before locking onto Aokiji and hitting him directly. Putting even more flame on him.

But he wasn't out of the fight, figuring that it was pointless to fight the flame. He might as well take it's user out and the flame will go away.

He launched up in the air with all his might, speeding towards the big bird. His fists were coated with the thick aura of Armament Haki. 

He reached full altitude and slammed both fists onto the top of the birds head. As the blows landed he realized that almost no damage went through, and when he looked carefully. The damage he did land healed instantly.

Realizing the threat of the being before him, he no longer held back. He launched himself back at the bird with Geppo and began to wail on the bird.

The bird kept trying to dodge the attacks but his unfamiliarity with his form and poor coordination kept him from realizing his amazing speed and agility to dodge the relatively slow attacks.

Soon being overwhelmed he unleashed a fiery aura around him temporarily keeping Aokiji from being able to beat him up.

With the time he gained, he flew up in the air at a very high altitude, and took a deep breath. 

Looking back at the situation, even without Haki, this was extremely winnable with his cards. His unfamiliarity with his fruit the only thing keeping him back. 

Seeing Aokiji mid air trying to rise up to him, he had an idea. Because the fire was constantly burning him, his Logia abilities were somewhat nullified meaning he could be touched as long as he willed.

So he willed himself to dive down and grab Aokiji with his two wings and dive down towards the ground. While speeding downwards at an alarming rate, he spun himself in circles disorientating the Ice man while even further increasing his speed.

he remembered in his past life, and common sense that the faster you hit something the harder your punch will be and the more damage it'll do. So if he body slammed Aokiji into the ground as fast as possible while as a bird and switched into his turtle form last second, carrying all that momentum will possibly kill Aokiji with the weight of the turtle.

So with that plan in mind, he sped as much as physically possible and at the last second just before landing face first. He switched from the majestic Vermillion Firebird, to the Impenetrable Earth Turtle, and slammed Aokiji into the Earth head first, with the weight of an island going Mach 10.
