It's not October yet, but I've wanted to write a Halloween SaNa fic since seeing their outfits both with Tokyo One Piece Tower and the Coca-Cola ad campaign. If you haven't seen them yet, please go check them out. Sanji and Nami match in both. They're so cute! ^^v


Halloween only comes once a year, just like any other day throughout the year, really… But what made Halloween special were the costumes. No, it was the candy. No, it had to be the party. No… All of these added to the fun, of course, but it wasn't just about that. Nami couldn't quite place it. Maybe what made Halloween so special was the fact that she never got to celebrate it as a child after Bell-Mere died. Living under Arlong's webbed thumb didn't exactly allow the opportunity for a "normal" childhood.

Well that wasn't supposed to happen today. The navigator frowned at the depressing thought. Thoughtlessly, her fingers clutched around a light blue headband, threatening to break off the fuzzy halo attached. A knock on the women's cabin door startled her enough to loosen her grip.

"Nami," Robin peeked her head into the room. A pointed, black witch's hat sat perfectly on her head. "Are you ready? Everyone is starting to set up for the party."

"Yeah!" Nami replied, giggling nervously. She refused to allow Halloween to be ruined by being stuck in the past. Bell-Mere would be disappointed in her if she let that happen. Glancing in the mirror, the navigator fixed the band on her head and pulled at the hem of her matching light blue mini dress. The heart-shaped cutout on her chest dipped dangerously low along her cleavage until she adjusted it back into place. None of the guys needed a free show. Grabbing a pair of feathered wings from off the bed, Nami held them up to her cabin mate. "Can you help me get these on, please?"

Robin took a step into the room, not bothering to close the door. Her witch's costume not only consisted of the hat, but also a broom and a fitted, black, long-sleeve dress. The only thing missing was a black cat to complete the look. The archaeologist set aside her broom and gently took the wings. Holding them out like a coat, she waited for Nami to put her arms through. "These are cute! You really made a good choice this year," she commented as she helped straighten the wings.

"Thank you!" Nami returned. "I only wish I could wear black like you. It looks so nice on you!" It wasn't fair. Robin was mature enough to look good in black. Nami always felt like a child playing dress-up if she even attempted the color. Taking another look in the mirror, she nodded her head. "Okay, I'm done." The two women left the cabin to join their crewmates.

Outside, Sanji was carrying various ingredients down the stairs from the kitchen. The sun was setting on the sea, spreading shades of orange and pink across the sky, but he had no time to sit and watch it. As captain of the ship, Luffy had decided that he wanted the Halloween party to be on the beach of an island they came across that morning. The cook never minded grilling outdoors. It was just a pain in the ass getting all of the necessities ashore. Franky had managed to anchor the Sunny off the shore in an alcove with deep enough waters, but it was still a bit of a walk to the beach that Luffy had chosen for their party. The blond sighed. Maybe it was a mistake to wear the red devil hoodie as a costume. It was simple to put on, but it was definitely too warm for running back and forth to the ship. Oh well. It would be cool enough once night came.

Sleeves rolled up and balancing the boxes of ingredients in his arms, Sanji made his way towards the staircase leading to shore… until a bright blue twinkle caught the corner of his eye. He turned to see Robin-chan dressed as a sexy witch, and… "Nami-swa〜n!" In a flurry of hearts, the love cook spun over to the navigator. "Nami-swan! Nami-swa〜n!" he repeated her name. "Nami-swan, my beautiful angel! We match!"

The navigator blinked and observed his costume. The red was a different shade for him. Not bad, of course, but different. A black pitchfork design decorated the front of his shirt. Matching black wings spread out from the back. The detail Nami liked most was the little devil horns attached to the hood. It made her smile before she coughed and put on a pout. Folding her arms, she spoke in a stern voice, "Sanji-kun! Everyone is going to think we did this on purpose! Now I have to change my costume!"

"No!" Sanji immediately put down the boxes and grabbed the navigator's hand. Bending down on one knee, it looked like he was about to offer a marriage proposal. Nami panicked and tried to pull her hand away. Robin giggled at the scene. It was too amusing. Still, the cook refused to move. "Nami-san," he spoke in a deep tone. "I promise to you here, now…"

"Sanji-kun, stop!" the navigator cried. This was so embarrassing.

"… No one will even see my costume," he continued without missing a beat. "They will be too captivated by your wondrous beauty and stunning… outfit…" His eyes began to wander as he said the last word. Nami could tell where he was looking.

"Idiot!" she yelled, smacking him in the forehead with her free hand. "Quit acting like a pervert!" Robin laughed in response and walked away, mentioning something about avoiding a lovers' quarrel.

Sanji grabbed the navigator's other hand and held both as he got to his feet. She still had a pout on her face. "I mean it, Nami-san," he said in earnest. "Please don't change costumes. You look beautiful."

A hint of blush rose in her cheeks despite her angry expression. Uncomfortable with his attention focused on her, Nami shifted her eyes and spotted the boxes the cook had put down. "What are those for?"

Following her gaze, Sanji looked down to the ingredients. "Oh, that's some of the stuff I need for dinner. Luffy wants a barbeque." Reluctantly, he let go of Nami's hands to pick up the containers. "I have to get these to the beach so I can get started. That rubber brain is going to start whining that he's hungry soon."

"Here, let me help you," Nami offered. She moved to take one of the boxes.

Sanji avoided her reach. "Nami-san, I can't ask you to help me. A lady should never need to carry anything."

"Don't be ridiculous!" Nami stretched up again, trying to grab the top box. Her tall, high-heeled boots caught her off-balance and she grabbed the cook's arm to steady herself.

Afraid that she was going to fall, Sanji conceded. "Okay, okay!" He removed a smaller box of spices from the tower and handed it to her. "A spice rack for my spicy angel." He didn't want to make any rack comparisons at the risk of certain death.

"Thank you," Nami replied. It was still ridiculous, but she didn't want to waste time arguing. While stepping off the ship, she noticed a devil tail sticking out of the bottom of the cook's shirt. Chuckling, she playfully grabbed the tail with her right hand and held onto it like a leash. "I really do like your costume, Sanji-kun," she admitted. "I'm glad you picked it."
