song- Left Alone, Sleeping With Sirens

Luffy found himself walking away from the burning building. He stopped and turned around to look at what he'd left behind. There were bodies everywhere, scorched and burned to a crisp. He started shaking, but didn't look back. He didn't want to know if Dark Luffy had killed the prisoners as well.

He knew Dark Luffy had no ounce of mercy. Those prisoners were dead. Even if Dark Luffy told him he'd save multiple people, they were always found dead, like all of the bad guys.

Luffy was only six, but had murdered thousands of people. Not on purpose, but it was his body that was used to kill. He was never conscious while it happened, which he was glad for. He didn't have to witness the carnage Dark Luffy enjoyed.

He was four when he first heard that voice in his head. The first thing Dark Luffy had ever done was to hit a kid in the face with a toy for the snack Luffy had really wanted but couldn't have. All the other kids in his orphanage were afraid of him after that. The fear only grew once Luffy was deemed mentally unstable. Talking to the voice in your head does seem like something is wrong with their brain.

But Luffy knew he wasn't sick in the head. There was a monster in there with him. His wing steadily turned black after that first incident, and every time Dark Luffy came out and killed someone, a new portion of his white wings would turn black. He had over 60 black feathers on his wings, but almost every single one of those feathers were the product of killing dozens, if not hundreds of people.

When Luffy was first admitted to a hospital for his problems, he ended up trapped in a straight jacket, hurting his wings by being so bunched up. Dark Luffy did not like that. The hospital burned to the ground, Luffy the only one left standing, not knowing what had happened. He was five when that happened. He left the scene in tears, crying for someone to help him. Help get the bad thing out of his head. Dark Luffy hadn't had a name back then.

After that, Dark Luffy had disappeared for a while. Luffy thought he'd gone away for good until he fell over the railing of a ship he was riding on to get to the next island, finally out of another hospital that had helped him with his anxiety. He wasn't treated crazy there, and Dark Luffy seemed to be asleep for all the time there.

But when Luffy fell over the edge, he blacked out and when he came to, he was on a completely different island. He didn't remember getting there in the first place, and had heard a few days later about a ship that had exploded. Someone had done it on purpose, since there had been nothing on the ship to blow it up.

Then Luffy remembered that he had smelled sour, and had ash on his hands. He couldn't figure out what the gross smelling liquid on his clothes was. It was oil. And he had somehow gotten from the wrecked ship to the next island. He had no idea how that happened.

Luffy had a violent bodyguard with him at all times. Dark Luffy would convince him that he needed help getting out of sticky situations. Luffy gave in eventually every time. The more stressed he was, the more excited Dark Luffy got, and the longer their conversations became. Dark Luffy was coming out more often, even when Luffy tried to isolate himself away from other people. Dark Luffy would take advantage of Luffy's fears and anxiety, manipulating the little angel with fake promises and reassurance.

And if Luffy ever tried to off himself, well… Dark Luffy was not happy. He may not be Luffy, but he was in Luffy's body. When Luffy had snatched a dagger to try and kill himself, the moment Luffy thought that, he was taken over by rage, and was punished by knowing Dark Luffy had killed people who Luffy had met to enforce to Luffy that he wouldn't be dying any time soon, and not by his own hand.

Luffy didn't know what Dark Luffy looked like, or what weapons he used to inflict his favorite activities. Luffy knew fire was a favorite of the monster inside of him, but Luffy never carried anything flammable, or that could start a fire. Luffy didn't carry anything with him. Anything could be used as weapons. He just had the clothes he was wearing.

Dark Luffy also liked pointy things, which Luffy never carried. He had to wonder if Dark Luffy had any sort of magic powers. It would explain it. But it wouldn't explain where Dark Luffy had come from. Had he always been there, since he was a baby? Or was he cursed by someone… he hoped it was the latter so he could someday break the curse. Someday he'd be free. He wouldn't be shackled in his own body, feeling like a dagger was constantly in front of his throat. He was both haunted and possessed at the same time.

Luffy walked away from the auction house, not a hair out of place. He was very hungry, since Dark Luffy took a lot of energy. It seemed like Luffy was eating for two. He was. To others, he just looked like a little angel with a big appetite. But he was eating for Dark Luffy as well. Well, he was trying to fill up what Dark Luffy left behind.

The angel walked along the ridge, getting further and further away from large populations. He'd just stay out here for awhile. And relax while Dark Luffy laid dormant for awhile. The only upside to all the killing was that Dark Luffy got tired for a while afterwards, and Luffy was in control for a couple weeks, or even months, before his demon poked his head out and spoke to Luffy. But the last couple of times he came out, the time he spent away became shorter.

Luffy sat at the highest part of the island and looked at the ocean below. He kicked his little legs against the air and rocks, staring out at the water below him. He thought it was pretty and leaned further over to watch the otters below playing with each other. He wished he had friends like the little animals below. That he hadn't weirded everyone out so much with his talking to himself and the random bouts of anxiety.

It would be nice to play with them down there… Maybe Dark Luffy would let me play for awhile. Luffy stood up to climb down the ridge and go to the little cove below him. His steps were made carefully as he climbed down the rock face. The wind blowing at him from behind felt nice, and he just closed his eyes for a moment.

The rocks his hands were holding onto split, and Luffy scratched his fingers and palms against the jagged surface, crying out and pulling them away immediately from the pain. But he started to fall down the mountain face. As the milliseconds went by, Luffy called out for Dark Luffy.

"Help me, Dark Luffy!" he screamed, everything going black. But he felt no pain.

"Thanks for letting me out voluntarily. Maybe I'll give you a little break, Luffy..." Luffy heard in his head as he woke up on the sand below where he had fallen. He smiled. A little break… That sounds nice.

It was two weeks after he'd called Dark Luffy for help that Luffy found himself caught again. He sat in a wooden cage, something Dark Luffy could easily destroy, being transported by ship to another island. There were other animals down there with him. They all seemed angry or scared. Creatures hissed and growled at Luffy from their own small cages. It smelled down there.

Luffy was calm, wondering why he was with a bunch of animals. Was he going to another auction hall? Would everything repeat not a month later? And Dark Luffy was saying nothing. It was quiet in Luffy's head. That must mean he wasn't in danger, right? If the monster inside of him was still sleeping, then Luffy wasn't in danger

Luffy had never been injured by anything, for Dark Luffy protected the body he was trapped inside. If Luffy was about to fall, Dark Luffy took over for less than a second, and suddenly Luffy was nowhere near where he'd almost fallen. Luffy had to at least be thankful for that.

Dark Luffy told him that he only protected Luffy because he didn't want his own body damaged. After all, if Luffy was dead or injured, Dark Luffy wouldn't be able to do anything. He can't heal Luffy, so if he's dead, he's dead. Luffy was threatened every time he almost injured himself, even if it was a total accident.

Food was brought down for him and the other animals. It was some sort of suspicious soup. He didn't eat it until he felt a little fuzzy feeling in his head, which meant Dark Luffy rolled over in bed. That he almost was about to wake up. Luffy shoveled the disgusting food into his mouth, and stole the cup from a nearby cat.

"I'm sorry," Luffy said as he ate the cat's share. "You're better off hungry than if I am."

Luffy rested for a few hours, enjoying the sway of the boat. Things were peaceful, even if the storage room he was in started smelling bad from animal waste. But things were quiet and there was no one around Dark Luffy would hurt or even see at the moment if he did wake up.

Luffy was lost in thoughts of freedom from the monster in his head. And Dark Luffy wasn't talking to him, which was nice. Luffy wondered how long the monster would stay quiet. He hoped for a long time.

"Pops, there's a trading ship coming up!" Ace told his father and captain. "We need supplies or Thatch is gonna die," he said darkly. Damn that stupid Teach! Just for a Devil Fruit, he tried to kill his crewmate, someone who was supposed to be a family member!

"We're making a raid. Call some of your men and get over there fast. We don't have time to dawdle," Whitebeard said coldly, though not targeted at Ace.

"Right!" Ace replied, going to tell some of those under him that they were making a raid and to get ready to board the other ship.

Luffy was broken out of his peaceful thoughts when people above started to scream. Luffy felt the tickle in his head. Dark Luffy was attracted to the screams, so Luffy stuck fingers into his ears as ear plugs. He couldn't hear the screams anymore, and the monster went back to sleep.

Some people came running down the stairs and started to take crates, ignoring all of the animals in their cages. Luffy just watched them, didn't say anything to get their attention, though he'd appreciate some more food.

As the crates steadily and quickly disappeared up the stairs, Luffy was more visible from the stairs. The last crate went up and the door almost closed, leaving Luffy with his fellow caged creatures, but then Luffy sneezed. The door creaked fully open again. Luffy slumped down further, wrapping his wings around himself to try and hide.

But now it just looked like a massive bird was sleeping in the cage. Footsteps grew closer, and he finally unfurled his wings and stared into a freckled man's face as he looked down at Luffy in surprise and interest.

"Who are you?" the man with an orange hat asked. Luffy hadn't spoken to anyone in a while besides his conversations with Dark Luffy and crying to be let go.

"I'm Luffy, but I'm fine here," the little angel said. Ace quirked an eyebrow.

"You're fine being in a cage surrounded by rancid animals?" he asked in disbelief. Luffy blushed a little and nodded. "Well that's too bad, because I'm not leaving a little kid here."

"No, no I'm fine! You don't have to take me with you," Luffy said quickly. He didn't feel like being around other people when he could just be by himself with some animals. "I'm fine to stay -"

"I'm hungry, Luffy…" the voice came up in his head. Luffy stopped his protesting at once, seemingly doing a complete 180. "Okay, I'll go with you," Luffy suddenly said, standing up shakily while the man in front of them seemed to burn off the lock and let him out.

"I- I'm hungry. Do you have any food?" Luffy asked quickly. Ace looked at him strangely. Something seemed off with this one. But it could just be because this little boy was… unique looking. Will different colored eyes and wings with dark feathers mixed with the pure white. Plus, Ace had never met an angel before. Or seen one in person. He shook off his suspicion of this boy. After all, he was just a little kid.

"We do, on my ship," Ace replied. Luffy nodded. "What was your name again?"

Luffy bit his lip. He was feeling Dark Luffy wake up. He was trapped now. Now that Dark Luffy was awake, Luffy would either go with these people, or kill everything on this ship and the one that had just raided.

"My name is Luffy."

"Nice to meet you, Luffy. I'm Ace of the Whitebeard Pirates. Were you heading anywhere we can drop you off?" Ace asked kindly.

"Nice to meet you, too. I wasn't really going anywhere. I live by myself, so I go wherever," Luffy told him after seeing the man's warm smile. Luffy was surprised he was talking to this man openly. He could even feel Dark Luffy perk up, wondering the same thing.

"Well, we'll drop you off at the next island if you want," Ace replied. "I'm sure no one would mind. After all, none of us have seen an angel before and it'd be nice to talk to one." Ace was lead to a board across both boats, leading to a massive one. Luffy felt like an ant compared to the thing. He was very small for his age.

"Thank you. I'll leave on the next island," Luffy said. "Interesting…"

Luffy shivered at the voice, but then felt it sinking away, going to sleep or pretending to be asleep. Dark Luffy had done that before. Just pretended that he was gone only to pop up when Luffy least expected. He really was a cruel creature.

Ace looked at him strangely again. He was sure something was off with this boy. He couldn't tell what it was, which was strange, but he knew it was there. Something was there.

Luffy stepped onto the big ship's deck, nervous immediately when he saw the massive man in front of him. He felt even Dark Luffy shiver. He wasn't asleep after all. He was just being sadistic.

This man was terrifying to be in front of. It felt like he was staring right through Luffy. Did he see Dark Luffy?

"Who's the kid?" a man with a bored face asked. Luffy said nothing, just continued to stare at Whitebeard in fear. He couldn't move his legs. Luffy felt one of his legs step backwards. He wasn't the one controlling it. Dark Luffy was terrified. "Get back on this other ship, now, Luffy!" the voice in his head boomed. Luffy stepped back again and turned to run back onto the other ship. But Ace grabbed him around the waist.

"Pops, stop glaring at him! You're scaring him," Ace scolded his father, who's glare disappeared with a smile.

"Sorry about that, squirt!" he laughed a… unique laugh. Luffy felt Dark Luffy bristle. He was offended by the name, and also knowing that he'd been so terrified of someone Luffy had never talked to. "Didn't mean to scare you." Luffy nodded numbly. He was conflicted. If he ran, Dark Luffy would be happy, but if he didnt… The monster in his head had never been afraid of anything, but he was so much of the man in front of him.

"I-it's okay," Luffy said quietly. "My name is Luffy…" he mumbled, uneasy with the embarrassment he could feel Dark Luffy angry about. "Be careful around this man, Luffy. You will leave as soon as possible or I will kill everyone here."

Luffy couldn't help but be confused with Dark Luffy's demand. If he was so afraid of Whitebeard, then why would he try to kill all of his important crew members? Dark Luffy… was terrified. Luffy had an idea pop up in his head. Maybe, if Luffy was liked by this man, Luffy could stay and Dark Luffy wouldn't have the power to kill anyone with the fear of Whitebeard.

But, if the monster in his head was afraid, then he was afraid for Luffy's body. Should Luffy be afraid? Did the monster think that Whitebeard would get to him through Luffy's body? Luffy didn't know what to think.

"My name is Whitebeard. Welcome to the crew, temporarily," the man said with a grin. Luffy nodded meekly, but stayed in that spot. He wanted to get away, but he didn't want to intrude and didn't know where anything was.

"Um… do you have a bathroom?" Luffy asked. When Ace laughed, Luffy's face turned red in embarrassment. Of course they had a bathroom! "Nevermind…" he said sadly. The man with a bored face took pity on the little boy.

"Come with me, and I'll show you the bathroom," he said in a monotone voice. Luffy had his head lowered as he followed the man, who introduced himself as Marco. Luffy was starting to become very uncomfortable with Dark Luffy now warning him of this man as well. The monster seemed to know something about these men.

Luffy needed to ask him what he was so scared of, which is why he wanted to go to the bathroom. He thanked Marco and closed the door behind him, locking it and hurrying to the furthest area from the wooden doorway.

"Why are you scared of them?" Luffy asked in a whisper.

"Because they won't hesitate to kill us if you do anything stupid."

"But… I only do bad things cause you make me. So if you leave me alone, we'll be fine," Luffy reasoned. This made Dark Luffy very angry.

"You are not in control while I am awake! You will do what I tell you to do, or I'll kill everyone!"

"B-b-but we both get killed if we do something wrong. If you don't do anything bad, th...then we'll be okay, right?" Luffy asked his voice shaking along with his whole body. When Dark Luffy was angry, it felt like Luffy was being smashed in on all sides. He just felt smaller and smaller, and more weak.

"You will do what I say!"

"O-okay. Okay," Luffy said hurriedly, close to tears. He bit his wobbly lip, trying not to cry.

"Don't cry!"

"S-sorry!" he said, doing his best to not cry, even though he felt like crying his eyes out and screaming as well. He hated this life. He hated Dark Luffy. And he hated that he couldn't control his own life or actions without having Dark Luffy threaten him into submission. Luffy cared too much about strangers.

Marco frowned when Luffy came out of the bathroom. There was no flush and he hadn't even heard the toilet lid go up, so why was he in the bathroom for so long. When Luffy looked at him, he flinched and looked at the ground, hating the unease that Dark Luffy was feeling. It made Luffy terrified.

But what was so scary about Marco? He didn't look especially strong. He looked like a normal guy, really. He wasn't buff or anything. Ace was bigger, but Dark Luffy wasn't terrified of him. Luffy could understand Whitebeard, but why Marco?

"Are you okay?" the blonde haired man asked with a frown. Luffy acted strange. There was something mentally wrong with this kid, wasn't there? Luffy licked his lips and nodded.

"I'm okay," he replied, trying to keep his voice from shaking. He felt claustrophobic in his own body. Why did it have to be like this?

"Okay, I'll show you where you're going to be staying. It's not much, but it is for guests, which we don't get a lot, so it'll be a bit dusty," Marco said, leading a reluctant Luffy through the halls and to a closed door. When he opened it, and turned on the light, Luffy loved the room. There were so many places to hide. The bed was dusty but had clean sheets, and there were many crates that Luffy could open up and hide in. Hide from everyone else. Hide from everyone he might someday kill. Someday will be made to kill without even remembering it.

"Thank you," Luffy said meekly, as he entered the room and stiffly sat on the bed, looking at his fingers.

"Yeah… well, you know where the bathroom is, so you can just hang out in here if you want," Marco said, feeling pity on the very antisocial child. "I'll come find you when dinner is ready." Then he closed the door, and heard the handle lock from inside. Poor kid.

"N-now what?" Luffy asked the monster. "Stay in this room and keep the door locked."

"Okay," Luffy replied quietly, not moving anymore other than the tears coming down his face. Dark Luffy didn't go back to sleep, and kept Luffy crying with the horrible unease coming from the evil being inside of poor Luffy.
