So this story is OC-centric, specifically my OC of Vice-Admiral Akauma, or Lady Keiko, a violent protege of Akainu. Lots of appearance by canon characters.

All in all I hope we can all have some fun with the world of One Piece. Enjoy, and please review.

Justice.

Only those who had earned the privilege, the right, could wear the coat emblazoned with Kanji that defined the Marines. She had earned it, reluctantly, through brute force and unrelenting ferocity. Pirates, criminals, all were scum to be eradicated. Her mentor had beaten it into a violent young girl who had hated him with every breath. The hatred made it easier for her to acquire something she had long sought after, a weapon capable of bringing down islands. Terror, fear, destruction, death, everything contained within a small, golden snail with a single button.

The buster call. It had only been called upon in extreme circumstances, the ultimate attack by the marines, unstoppable and indifferent. Ten ships commanded by five admirals with no limits, no orders, except one: destroy everything. She had pressed it five hours ago, and now such a fleet converged in the New World, on the last known location of Marshal D. Teach, otherwise known as the Pirate Emperor Blackbeard. Three comrades had come along, two out of duty, and one for the destruction. The fourth, alongside herself, had been specially chosen. Vice-Admiral "Yokokaze" Gina had shown time and time again her strength in battle. "Begin the Buster Call" she ordered, the Den Den Mushi transmitting her orders across the fleet.

-A-

Two hours later.

Only three ships remained, only two Vice-Admirals left, survivors of Blackbeard's retaliation. The pirates had boarded them long ago, ragtag, bloodthirsty men waving weapons and killing all in their path. Gina considered it lucky Blackbeard had not made an appearance. The battle was being led by the 1st Fleet Commander Jesus Burgess. The Emperor was there, however, his presence an oppressive force encouraging the scum under him.

Tall and imposing. two slender katana giving her a long reach, the marine fought in a circle, calm as a lake. It happened as the last pirate fell, the deck exploding in a shower of splinters. A hulking fighter came from below, humungous fist aiming for her face. "Twin Gusts!" yelled the Vice-Admiral, turning on the spot and unleashing two whirlwinds that held its momentum. She jumped back, not wanting to go toe-to-toe with the hulking mass if she could avoid it. Grinning with large teeth, Burgess bent his arm, pointed his elbow at Gina, and let forth a blast of air pressure. The Marine tensed her body. "Tekkai!"

The blast knocked the wind out of the marine, allowing her to stand up for a few minutes before sagging to her knees. "Wi~hahaha!" laughed Burgess triumphantly, tossing a charging marine off the ship. "Can you give me a challenge, girl? Let's fight!" He aimed a punch at her weakened form and she dodged to the side, slashing twice with both swords. Blackened skin deflected the attack, the pirate grabbing her foot and swinging Gina into the deck. "Try again! Maybe those toothpicks will get through my Haki."

Gina picked herself off the floor and spat out a tooth, swords flipped around, her body rising in a lethal spin. Once, twice, three times, each blow just bounced off his hardened skin. "Hado Elbow!" At close range every part of her body was pounded by the sheer pressure. Still laughing, the Commander of the First Fleet picked her up by the neck, looking sadistically at her. "Weak! Is there no one strong to fight?!" he yelled in her face, smashing her into the deck and pulling her back up.

A flying kick knocked him to the other side of the ship. Gina dropped and a slender hang yanked her into a comforting embrace. Even with the blood trickling into her eyes, she recognised the new face. "Keiko…" she whispered, and passed out.

-A-

Her rescuer, and initiator of the Buster Call, stood up and handed the unconscious marine to a lieutenant behind her. "Get her and the men away from here. Regroup, and then mount another attack once I take out Teach."

"But… Vice-Admiral, that's suicide! We have only one ship and a handful of men. We have to retreat, Lady Akauma" he protested, cringing from the fierce glare she responded with.

"You coward. The only reason you still have your teeth is because I need you to save Gina. Now go, unless you want to fight Blackbeard's lackey." He stepped back and then hurried to leave the ship. Hearing the loud footsteps behind, Keiko flipped backwards, landing on Burgess' massive shoulders. "Not going to fight fair? Good. I wasn't going to either" sneered the Marine, bringing down both fists on his head and twisting her legs to flip him into the deck, feeling the strain in her muscles. Keiko somersaulted away from his vicious swipe, vanishing a moment later.

Before he could attack again, her fist slammed into him. It thudded against the muscular black chest, and Burgess looked down with a smirk. "Hell" she muttered an instant before his hand crunched into her face, throwing the marine back across the deck and into the railing. Feeling her broken nose and ignoring the pain, she twisted it back into position, grunting at the sensation.

The scent of her own blood invigorated the Vice-Admiral, and she kicked out, launching a blade of air pressure at her opponent. The elbow destroyed the attack and then Keiko was behind him, her knee rammed into his groin. Burgess went down with a pained grunt, but he wasn't finished, snatching for the Marine who had humiliated him. Appearing above, the Vice-Admiral was well out of reach, and slammed her feet into his face, sending both through the ship. The ocean met them, Burgess hitting the surface with his back. Seeing him still amidst blood and water, unable to fight, she swam back up, feet aching. Not exactly her best fight, with aching bones and a broken nose, all you needed in battle was the ability to destroy everything in your path, regardless of the consequences. That was Absolute Justice.

"Now, for your boss" she muttered, tearing off a sleeve of her suit and using it to stem the bleeding. In the meantime, she let her observation haki sweep across the entire battlefield. Only Gina remained of her Vice-Admirals, and she was currently getting further and further away. "Cowards. I'll take on Blackbeard by myself."

Scanning, she finally found him, guiding the ships with the Quake Quake fruit's powers and keeping them together with the Shadow Shadow Fruit's. She hesitated at the thought of someone wielding two Devil Fruits, an aberration by normal standards.

Then again, the New World was anything but normal.

Swimming quickly through the ocean, her haki guided her straight and true to her opponent. She jumped up like a dolphin, jack-knifing and landing on the flagship.

Short and fat, unshaven, his appearance repulsed the Marine. A culmination of every pirate, every scum beneath a black flag. That was Blackbeard; worse than scum.

"Ze~hahaha. Look what fate has in store for me today! What is your name, girl?"

"I am Vice-Admiral Akauma of Marine Headquarters!"

He took a step back, then grinned. "Akainu's protege? How comical" laughed Blackbeard, clenching his fists and gathering black smoke around his body. "You don't appear to have a devil fruit, but you will still not escape my pull!"

Keiko gasped as she found herself pulled off the deck, flying through the air into the pirate's hand. Blackbeard grinned triumphantly and slammed her down, shockwaves pounding her body over and over from his palm. He let go and stepped back, panting from the exertion.

"That all you got, scum?" she spat out, crimson dotting the ship's deck. Blackbeard just continued smiling, a tornado of smoke rising up from his back and reaching out feelers. Keiko leapt and ducked, flinging herself overboard to swim deep where the Shadow Shadow fruit's power couldn't reach.

The cool water calmed her down, providing release for her aches, but it would have to be brief. Manoeuvring below, she kicked violently, propelled upwards and erupting like a geyser beneath Blackbeard with an uppercut that staggered the Emperor. She disappeared again and punched him in the stomach. He doubled over in pain, and she broke every bone in her hand; it was like hitting a wall.

Cursing, she tried to recuperate but that same wall slammed into Keiko like a tonne of bricks. The Vice-Admiral rolled onto her front, trying to get up. "Damn it. You're dead, fatso" she called out, gasping on the deck, laughing to herself hysterically. She found the red overtaking her now, matching Blackbeard's crazy exuberant expression with her own. The Vice-Admiral was vaguely aware of him taking the same stance from before.

"Ze~hahaha, you have spirit, little girl. Come here!"

Keiko swore and tried to jump away, but a black tendril caught her leg, pulling the Marine into his gathering sphere of shadow. Instead of punching the Vice-Admiral however, Blackbeard continued sucking in more and more of the surrounding environment. A great gravitational force emanated from the Emperor, cracking the deck and pulling in the people around them. Even his own men were caught up, swirling around with Keiko amongst them, vainly struggling to escape.

Slowly they reached the centre and the last thing Keiko saw amidst her rage was Blackbeard's shit-eating grin. "It is not my fate to be defeated here. Black… Star!" he yelled, and the darkness exploded.


I'm mostly curious about whether she's a well written female character. Next, we have the Fleet Admiral himself, and a surprise cameo.
