Hi Guys! This is a plot bunny that has been hopping around my head for a while and I needed to get it out. I have a vague idea of where this might go and it's a bit of a change from the ocean falling into one piece thing, which I really like to write. Speaking of which I have tworry other stories on the go that I haven't posted yet, but I will when I write a few more chapters of each so I'm a bit ahead. But anyways please enjoy this story, I know the first chapter is never much to go on but feel free to let me know what you think!

Luffy's Guardian Angel

Chapter 1

Why? Marine Girl…

Smoked filled her lungs, burning her throat and causing her eyes to sting. Her rifle felt heavy in her hands, like every round she hadn't fired yet weighed tons. She quickly ducked behind a pile of rubble dodging oncoming bullets. Her hands shook and her head was pounding. Why? Why? WHY!? She squeezed her eyes shut with a childish hope that maybe when she opened them… she wouldn't be here. She wouldn't be in the middle of Marineford, fighting for a cause that she was starting to question. They were the marines. It was their job to get rid of pirates. Pirates were bad, marines were good. Why couldn't it be that simple? But it wasn't and it wasn't ever going to be. That's why she was confused.

An explosion went off nearby, almost blowing her ear drum and showering her with ash.

She looked over her shoulder scanning the area. This didn't feel right. She should be worried shouldn't she? Portgas D. Ace had been freed by his brother Monkey D. Luffy. She should be angry. But she wasn't. When she watched Straw Hat reach the execution platform and free his brother she felt… relieved. So completely happy that she almost cheered. But that was wrong. Fire Fist was a pirate. Pirates were bad. But…

What if they weren't? What had Fire Fist done to deserve death? Sail? Not followed every single outrageous rule the government set? If not, then what? Being born? Living? That wasn't a crime justifiable by death!

Was she fighting for the wrong side?

She bit her lip and stood. Running back into the chaos, dodging and maiming but never killing.

These pirates were risking everything for one man. Straw Hat was fighting to the death to get his brother out alive. What was she fighting for? Their goal seemed so clear, so just. Why couldn't hers? She had to know. She had to get to Straw Hat. She had to know how he did it. How he knew what to fight for so clearly that it was as if it was written everywhere he looked. A constant reminder.

She didn't even know what it was that she lived for anymore.

So she ran, never once looking away from the duo of brothers that fought together like a well- oiled machine. Then Akainu showed up. Just when she thought that they'd get away, Ace turned and launched himself towards the admiral in a blind rage that caused her heart to cease. No no no no no no no no! They had been so close! You idiot! She pumped her legs faster running so fast she thought her lungs would burst.

Straw Hat desperately called to his brother, begging for him to run. But… he dropped to his knees his body unable to push any further. Her eyes widened. NO!

Akainu noticed Luffy's sudden weakness and turned on him with a smirk. Ace ran, yelling Luffy's name. Akainu pulled his fist back and Ace was just about to slide in front to take the blow. To protect his family.

But she was faster.

She slammed into Ace's side throwing him a good distance away. He was on his knees in seconds hoping that his brother was okay. Hoping he was still alive. What Ace saw was not what he expected. Silence seemed to fill the battle field, everyone nearby who witnessed what had just happened froze. Pirates and Marines alike.

Ace gaped. This… there… why?

Luffy looked up from his brothers vivre card. Eyes filled with horror and heart completely still. His brain worked too quickly telling his eyes that he should be seeing his brother, impaled through the chest with a fist of lava. But when his senses caught up with him, that wasn't what he was seeing. It wasn't his brother. It was a girl. A young girl with long black hair, and wide pain filled blue eyes that seemed to be staring at nothing.

Akainu raised his brow and scowled, pulling his fist back, sliding it out of the girl's stomach with a disgusting squelching sound that was accompanied by a small hiss. The girl dropped to her knees and slumped forwards into Luffy who was too stunned to move. Her chin came to rest on his shoulder and he subconsciously wrapped an arm around her waist and his hand came to the back of her head, holding her up. He watched silently as his brother ran over to him, but he couldn't hear his yells. All Luffy could hear was the ragged breathing of the dying girl in his arms.

The dying girl that had just saved his and his brother's lives.

Blood dripped down the girl's back, staining her previously white uniform, and coating Luffy's forearm in the warm liquid. The boy tried not to pay attention to that, trying to ignore the urge to wince at the amount of it there was.

Marco snapped out of his shock and growled, launching himself at Akainu as he made to attack the three again. With the help of his crewmates and Jimbei they managed to push Akainu back. That had been way too close.

Luffy turned his head slightly towards the girl. "Why…?" He whispered unable to make his voice go any louder. He felt the girl shake and he tensed before realizing she was laughing. A pained, desperate laugh but a laugh nonetheless. He vaguely heard Ace scream for a doctor.

"I've been following your adventures for a while now… everything you've done…" She coughed and blood splattered on the ground behind him. "Every fight you've been in… was to help someone, right?"

Luffy could only listen, unsure of where this was coming from. He didn't know this person. Why would she give up her life to save him and Ace? He didn't understand, so he asked again a little more firmly. "Why?"

"I've been asking myself that since this battle started." Her voice was growing weaker, Luffy could tell that she didn't have much time left. "Monkey D. Luffy, future pirate king. How do you know what's worth fighting for?" She asked quietly and suddenly she went limp, Luffy tightened his hold on her, now having to support all of her weight.

Ace dropped a hand on his brother's shoulder which caused the younger to look over at him. "We have to go Luffy."

Luffy moved to stand, the girl still clutched in his arms, but he found that he couldn't. His body had been pushed too far past its limits. Ace seeing his struggles pulled the girl from his arms and laid her on the ground, then picked his brother up with ease and carried him on his back. Just as he turned to run Luffy stopped him with a shout. Ace looked at him in confusion and Luffy stared back with an unwavering gaze. "I'm not going to leave her here."

Ace looked over at the girl who saved his life. Her body soaked in blood but her face was at peace, as if she were sleeping. He gave a single nod before scooping her body up in his arms, relying on Luffy to hold on tightly so he wouldn't fall.

Then he ran full tilt back to the whitebeard ship.

Well that's all for now! I know it's short, the first couple chapters will be but depending on reviews they'll get longer:)

Hope you enjoyed!
