A few weeks after partng from Whitebeard, she had stopped for some supplies. She was just passing Little Garden when a ship caught her attention. A ship sporting a Jolly Roger with a straw hat. A laugh escaped her throat.

'Luffy, of course you would put your straw hat on your Jolly Roger.'

Directing Calcifer to the island she hopped off him and onto the ship. Setting her bag down she pet Calcifer's head before the Sea King dived back under the water. She noticed no one aboard.

'Must still be dealing with Broque Works. Should I intervene? ...Nah.'

Luna began familiarizing herself with the ship. She noticed the damage that Reverse Mountian inflicted on the ship.

'Man the anime doesn't even cover the damage the Marry sustained.'

She heard movement in the forest next the ship. Luna walked back to the stern of the ship to wait for the crew. She watched as the several familiar figure boarded the ship, including a certain straw hat. She almost gave herself away when the swordsman and cook argued over their kills. Luna was silent as the ship moved through Little Garden. Two familiar giants stood at the edge of the island as they exited. Upon making eye contact with the giants, she gave a wink while holding a finger to her lips. The Island Eater emerged from the sea, scaring most of Luffy's crew, as her baby brother laughed from his place on the figurehead. The two giants yelled for the crew to keep going straight. Luna watched as they entered the Island Eater's mouth just to see the giants preforming their attack. The attack blasted through the Island Eater making a massive hole through the back of the fish. The Marry made it through with little issue and no one took notice of her presence. She decided to have some fun with the Strawhats. She moved to the railing that over looks the lower deck. Laying an arm across the railing while her head rested on her other hand.

"Well that was exciting."

Nami responded, "I could have done without that excitement."

"Sadly Luffy only knows excitement. He would anything if he thought it would be fun."

She watched as navigator froze at her voice. Turning Nami made eye contact with a woman on the upper deck. She had long white hair that hung over her shoulder, ocean blue eyes gave Nami a knowing look. She wave her hand nonchalantly.

"Hello."

Nami screamed loudly catching everyone's attention.

"Who's that? Is she one of Broque Works?" Usopp yelled as he hide behind the mast.

The yelling caught Luffy's attention as well, and upon seeing the woman he let an excited yell. Using his arms he catapulted to the woman. She stood in time for the boy's legs to wrap around her waist as his arms wrapped around her head. Laughing Luffy hugged her tight, a laugh escaped the woman as she stumpled back. Her hand coming to rest on his back to stamble the boy.

"Luffy what's going on how do you know her?"

"Luffy How Dare You Handle A Lady So Violently!"

The woman laughed as she waved her other hand, "he's fine. I'm used to dealing with this."

The crew prepaid for anything as they watched the hand on Luffy's back slide up to the back of his head. They watched as she began scratching the boy's head. Luffy's crew watched in amazement as the rubber boy all but melted under her touch. The boy slide down so that only his arms were wrapped around her waist, she continued scratching his head. Luffy buried his face into her stomach.

"I apologize for frightening everyone, I couldn't stop myself from having some fun. My name is Monkey D. Luna and Luffy is my younger brother."

"BROTHER!?!?!"

She stopped scratching Luffy's head as she stepped back, causing the boy to whine. She walked down to the lower deck with the rest of the crew.

"So you are the crew Luffy has gathered? May I have introductions?"

Sanji wasted no time in greeting the new woman, "ah I my lovely lady am Sanji, I'm the chef of the crew. But you may call me anything Luna-swan."

A soft giggle left her as she nodded at the cook, "pleasure to meet you, I apologize, I know that Luffy's appetite can be stifling."

Zoro stepped forward pushing Sanji away from her, "the name's Zoro. You really Luffy's sister?"

Luna hummed softly with a nod at the swordsman, "yes and it's a pleasure to meet you Roronoa Zoro. Last time I heard you were a bounty hunter."

Zoro scoffed as a blush stained his cheeks, "I never claimed to be a bounty hunter."

Nami walked up to the woman, "I'm Nami the ships navigator." She pointed at Vivi.

"That's Vivi and the duck next to her is Karoo, and the one hiding behind the mast is Usopp."

Luna looked over a the princess, "you're Princess Vivi of Alabasta aren't you? I'm sorry for what's happening in you country."

Vivi looked surprised, "you know of Alabasta?"

Luna nodded, Luffy came to stand behind her.

"I have been traveling the Grand Line for about a year and a half now. I've stopped by Alabasta on my travels."

The crew of the Going Marry looked shocked, "YOU'VE BEEN HERE A YEAR?!"

Luffy was now clinging onto his sister's back. "Oi oi sis have you come back cause your promise?"

Luna laughed at the boy's excitement, "yes Luffy sorry I didn't make it back earlier. I had some errands to run."

Nami noticed Luna's lack of a Log Post, "hey if you've been on the Grand Line for almost two years where's your Log Post?"

Before Luna could respond Luffy yelled out, "Luna doesn't need a Log Post thingie she has cool powers."

A giggle left the woman, "as Luffy has so kindly pointed out my abilities allow me to control and manipulate water. I'm able to change ocean currents, so I never need a Log Post."

Usopp stepped out from behind the mast, "another devil fruit?"

Nami looked shock, "you're able to change currents? Then you're going to be a big help."

Luna just smiled, "I'll do my best, and no Usopp my power does not come from a devil fruit. I still have my ability to swim."

The crew went back to their potions. Luna keep an eye on Nami, remembering she will become ill soon. Luffy had final detangled himself from his sister to take his spot on the figurehead. It wasn't long before Luna noticed Nami's face becoming red. Nami handed Vivi the Log Post and Luna wasted no time in caughting Nami as she fell.

"Nami!"

Luna scooped the navigator up as the others came over. She made her way to the girls' room while the navigator weakly protested.

"Luna I'm fine just tired."

The woman's blue eyes looked down at the girl, "oh is that why your body temperature is up and you had a fainting spell?"

Nami pouted and crossed her arms as the older woman laid her on the bed. Vivi and the boys followed into the room. Luffy stopping behind his sister. Luna turned to look at the crew.

"Nami's temperature is elevated. Luffy, Usopp I'll need clean cold water and a cloth. Sanji until I can identify this only warm liquids."

Nami protested behind the woman again, "I'm fine I don't need all this. Also since when were you a doctor?"

Luna turned back to her, "I never said I was a doctor. In fact I don't fully believe that if this isn't a simple illness that I will be able to do anything. I have little knowledge of crafting medication, though I will be able to decipher if it's viral or bacterial shortly."

Vivi walked forward, "how will you be able to do that?"

Luna turned to look at the Princess, "if anyone else comes down with the symptoms it's viral if not bacterial."

Luffy and Usopp can back with the needed materials. Luna pointed to the table beside Nami's bed. "Place them there, we'll have to take shifts to watch over Nami. I don't want her alone for too long. I'll use my currents to take us to a nearby island, that's known for their doctors. Is that alright captain?"

Luffy nodded with his usual smile, "yep you know more about this stuff."

Luna gave a nod before looking back to Vivi, "Vivi may I ask you to take the first watch? All you have to do is monitor her temperature and keep the cloth damp. Come fetch me if there are any changes; good or bad."

The others watched as Luna made her way on deck. Zoro stepped up next to Luffy, "Luffy you sure she know what she's talking about?"

Luffy just smiled at the swordsman, "Luna's always been smart with this stuff. If she says Nami needs a doctor than she needs a doctor."

Zoro nodded as Sanji came back with some warm broth and tea for Nami.

Hours passed before Luna definitively announced that Nami had in fact a bacterial infection. After a formal look at Nami she deduced that it was caused by a bug bite.

"It must have happened on Little Garden which is even worsening news. That island has ancient bacteria, ones that little to few doctors have studied. The island I'm taking us to luckily has one of those few doctors. But had I not known about this doctor Nami would have most definitely died."

Standing Luna walked over to the desk in Nami's room. Nami was shocked as she pulled the newspaper she hid. Luna handed the paper over to Vivi, "Nami was going to use this to try and bypass her treatment. Vivi she doubts her importance to you, she believes you will choose your people over her health. So Princess who will you choose?"

Vivi stared at the paper in shock, yes the civil war was getting worse, but she wouldn't sacrifice her new friend. Luna told the Nami would most definitely die if not treated and that she only had five days. She looked at the white haired woman, those eyes they knew what she was going to say.

Vivi's face morphed into one of determination, "the faster we get Nami better the faster we can get to Alabasta."

Luna smirked at the girl, "that's what I expected. Nami now you have no leverage. You will be seeing a doctor whether you like it or not."

Luna changed the cloth on Nami's head, her fever has only worsened. She knew soon Wapol would show up that meant they were less than a day away from Drum Island. Knowing Luffy would have no issue handling the moron she put all her force into Nami. Vivi sat diligently next to the two other women to lend her assistance. The ship shook as Wapol boarded without looking behind her Luna's voice rang out.

"Sanji please go assist the others with the visitors, the disturbance will not help Nami."

Sanji nodded as he left the room, Vivi asked the unspoken question, "Luna-san how do you seem to know everything going on?"

Nami listen for the answer, the older woman signed, "do you by chance know what Haki is?"

Vivi shook her head, "well it's the ability to use spiritual energy that everyone has, most just fail to notice it or just never have the chance to unlock it's power. The Haki I utilized is Observation Haki, it allows me the ability to sense others in the vicinity. It's perfect if your enemy is skilled at surprise attacks."

Luna stood, "Vivi please watch over Nami, the visitors have been removed. I shall go to see what I can do about getting to the island faster."

Upon reaching the deck she saw the boys looking over the port.

"Seems you had some fun."

Luffy turned to his sister with a scowl, "just some dumb metal mouth trying to eat our ship."

Luna ruffled the boy's hair before setting his hat back into place.

"Luf I need your promission to try and get us to the island faster."

Luffy's smile came back to his face, "whatever you gotta do sis."

Nodding she moved to the port side by Usopp, "Usopp you might want to back up please."

Before the boy moved she gave a loud whistle. Like with Whitebeard it was quiet for a few moments before Calcifer broke the water's surface. Usopp screamed at the sight of the Sea King. Zoro and Sanji looked at the beast in shock, while Luffy just had stars in his eyes.

"SO COOL!!!"

Chuckling Luna rubbed Calcifer's snout, "hello again Calcifer I hope I didn't interrupt anything?"

The sea dragon shook his head as he nudged her, "would it be alright if I asked for your assistance getting to Drum Island. It is the upmost importance we arrive there quickly."

The Sea King nodded his massive head. Turning back to the boys, "will one of you fetch me a rope? Calcifer agree to give us assistance."

"Hey didn't that metal guy want to get to Drum Island?"

Luna poked Luffy's forehead, "don't worry about that baby brother. That man is nothing but trouble."

Luffy nodded at the woman as Sanji walked over with some rope. Walking to the bow she secured the rope around of the bottom half of the figurehead, tossing the rope to Calcifer. The Sea King dived under the water once he had the rope.

"Hold onto something the beginning is always jarring."

Luffy scurried to the figurehead while the others grabbed onto the railing. Luna just stood at the bow behind Luffy as Calcifer jerked the ship forward before speeding to Drum Island. It took about two or three hours before the island came into view.

"There that's the island we were heading for, Drum Island."
