A/N: This is my second fanfiction. This time it's a crossover between One Piece and Akame Ga Kill. I hope you enjoy!

Akame Ga Kill: Kill the One Piece

"Ow…" Luffy said as he got up. "What just happened?" He as he looked around, checking his surroundings, recalling what happened.


FLASHBACK START

Luffy was currently on the battlefield that was Marineford, running away with his older brother, Portgas D. Ace.

All the while, Admiral Akainu was in hot pursuit of them.

"Fire Fist and Straw Hat! I vow to never let you two escape!" Akainu said charging even faster.

Still focused on running, the two brothers ran for their target even more determined. Seeing this, Akainu switched to a new strategy. But this thought was short-lived after what he just saw.

A purple yin-yang symbol along with a circle pattern, appeared out of nowhere.

"What the hell is that?!" Ace yelled stopping in his tracks.

"Huh?" Luffy said, still running. He never saw it coming. And he just ran straight into the purple circle. The circle immediately disappeared, along with Luffy. Ace frantically looked around, but he didn't see Luffy or the circle.

"LUFFY!" He screamed, making the entire battlefield go silent. Even the admirals couldn't process what just happened.

"Ace-san…" Jinbei said, looking towards him.

FLASHBACK END


Luffy then heard a scream, and looked towards the direction of the sound. There was an extremely bright light being emitted from there.

Luffy ran towards that direction at full speed and was completely enraged at what he saw.

A big demonic dog smiling opening its mouth while holding onto the upper half of a purple haired woman with a giant pair of scissors, a pink haired girl with two long pigtails somewhat battered with blood dripping from her arm, a auburn haired girl with a long ponytail with a malicious grin, and a lot of people wearing armor.

In short, it was a picture of hell.

"SHEELE!" the pink haired girl yelled.

Luffy on the other hand, had his hand gripped in fists. He was beyond pissed off at the sight.

He completely lost it when he heard the auburn haired girl yell gleefully, "KORO! Finish her off!"

With his hair shadowing his eyes, he slowly walked towards the scene.

"Hey, who the hell are you?!" the auburn haired girl shouted.

Luffy said nothing as he walked toward her, seething in rage. Luffy pulled his fist back.

Gomu Gomu no…

"Hey, what're you-"

She had no time to react as Luffy's fist punched her square in the jaw, breaking it.

Pistol!

The auburn haired girl was sent flying, hitting the ground a couple of times before she finally rolled to a stop. The pink haired girl had a look of shock on her face.

"My name is Seryu Ubiquitous" the now identified Seryu started as she held her mouth with a psychotic look in her eyes. "For doing that, I shall exact justice on you!" She yelled.

She earned another punch to the face, only this time, it was much harder.

"I don't give a fuck about you." Luffy said walking toward Koro, who hesitated when it heard Seryu scream after being punched by Luffy.

Koro let go of Sheele and lunged at Luffy, but Luffy quickly dodged it and caught Sheele in a bridal style position. "You okay?" Luffy asked as he returned ran toward the bushes.

"Y-yes. Thank you." Sheele said, blushing. Luffy had his heartwarming grin on, satisfied with her answer. "Hold on, I'll take you to your friend" Luffy said as he ran to the pink haired girl.

"Sheele!" the pink haired girl said as she saw Sheele. "Mine!" Sheele said as she saw Mine. "Hold on a second." Luffy said cracking his neck, even though he's made of rubber.

"What are you going to do?" Sheele asked as he saw Luffy bringing the lower half of Sheele's body. "My friend Chopper showed me how to do this." Luffy said aligning the two halves of Sheele's body together. Then, in a mere 10 seconds, Sheele's body was recovered and back together in One Piece.

"How did you-"Mine started as she saw the speed of Luffy's hands. "Less talking, more action." Luffy said as he walked toward Koro pounding his fists together.

"You guys sit this one out, I'll handle this." Luffy said.

Mine and Sheele looked at each other for a moment, but silently agreed. They began to observe Luffy's actions.

Koro lunged at Luffy again, this time unleashing a barrage of punches.

Gomu Gomu no Gatling!

Luffy countered with his own punches, and they were at a stalemate. Were.

Koro then lunged at Luffy again with his mouth open wide, intending to completely devour him. That was a dumb move on its part.

Luffy then jumped in the air and yelled-

Gomu Gomu no Stamp!

Koro was immediately planted in the ground and couldn't get up.

Gomu Gomu no Missile!

Koro was loosing consciousness at this point, but…

There were footsteps. Luffy looked behind him and saw a group of people surrounding Mine and Sheele. They didn't seem to be enemies, though. They were all talking, it was inaudible. Then they all looked toward him.

Everything was silent until they heard Luffy yell-

Gear Second!

As he pumped his legs two times. Koro slowly looked up at Luffy and he lost his demonic look.

Luffy didn't even flinch. He jumped once more and yelled-

Gomu Gomu no Stamp Gatling!

Koro was showered with an inconceivable amount of stamps, at a blinding speed.

"HOLY SHIT!" the group of people shouted.

Soon he was literally smashed into the ground, with only his core remaining. Luffy walked up to the core and picked it up. He looked at it, then immediately crushed it in his palm as he calmly walked toward Seryu.

Seryu was beyond scared. "Wait! This isn't how it's supposed to end!' She shouted frantically, looking around for her reinforcements, who have all ran away after seeing Koro's ass being kicked by Luffy.

"Justice is supposed to prevail!" She yelled. She clutched her head, kneeling. She looked up only to be sent away flying again.

"Jet Pistol"

Luffy said walking toward the downed Seryu.

The group of people, known as Night Raid, watched intently as Luffy started punching Seryu's face until you could barely recognize it.

"I have one question." Luffy said, grabbing Seryu's neck. Seryu started shedding tears and barely audible, said "Yes?"

"Do you have any final words?" Luffy asked, tightening his grip around her neck. Seryu nodded her head no and Luffy then delivered the final blow, smashing her skull, instantly killing her.

The members of Night Raid all had different reactions.

Akame retained a neutral expression, but her eyes widened a couple of times.

Lubbock was "tending" to Sheele.

Mine stared at Luffy in sheer fascination.

Bulat had a flirtatious/ curious look in eyes.

Sheele looked on with a small blush.

Leone was grinning the whole time, sometimes making punching motions as Luffy beat up Seryu.

Najenda simply stared at him, fully intending on making him join Night Raid.

Tatsumi, well, he was dumbfounded and realized just how weak he really was compared to Luffy.

Luffy walked toward the group with his usual grin. All the girls except Najenda were blushing, and it took all of Leone's willpower not to tackle Luffy with a bear hug.

"So, is your friend okay?" Luffy asked.

"Yes." Mine said. "Thank you so much." Mine started tearing up.

Luffy held her in his arms. "She's okay, isn't she? Why are you crying?" Luffy asked.

"Because, please join Night Raid! We need your kind of power to clean up the filth that is the capital!" Mine pleaded.

"Capital?" Luffy asked.

"Allow me to explain." Najenda started. "The Imperial Capital is a corrupt empire that needs to end. The cause of this corruption is the prime minister manipulating the emperor from the shadows and making him make terrible and unwise political and economic decisions."

Luffy started picking his nose as she talked. Mine looked at him with disgust, but kept her mouth shut.

"We, Night Raid, and the Revolutionary Army plan on cleaning up the Empire and its corrupt ruler, Prime Minister Honest, so that people can live in peace and prosperity." Najenda finished.

"So, that means I can beat up a fat, old guy right? Luffy asked.

Najenda face palmed.

"I'm already starting to like this new kid." Leone thought.

"Will you join Night Raid?" Najenda asked.

"I dunno, I gotta think about it for a sec." Luffy said as he brought out a giant piece of meat from his pocket.

Akame immediately perked up, catching sight of it, looking at Luffy with jealousy and desire. Luffy took note of this and immediately held it close. "You can't have this meat." Luffy said assertively. Akame looked downcast and turned the other way.

"Do I get a lot of food in Night Raid?" Luffy asked with a neutral expression.

"Yes, Akame makes really good food there." Najenda said.

"I'm in." Luffy said without hesitating.

Akame perked up and immediately ran up to Luffy.

"Which means 50% of your meat now belongs to Night Raid." Akame said.

"An extra 40% for me, of course." Akame finished.

It took a moment for Luffy to process what she just said. And when he finally understood…

"WHAT?!" he yelled.

"Mission Complete." Mine said. "Time to return to the base."

All the members of Night Raid rushed through the forest back to the base, with Akame staring at Luffy's meat the whole time they were traveling.

"But wait…What about my Nakama? Luffy thought.
