Ds Come In Pairs

She slightly trembled under his tattooed fingers as they tenderly brushed against her skin, across her neck, up her face and gripped her hair, with just enough force to make her body tingle with anticipation.

"Will it hurt?" She breathed out.

A seductive smile slipped on his lips. He leaned closer to her, his hair faintly touching her nose, letting her inhale his smell, and whispered in her ear, "Not at all."

She wanted to say more, but he licked her ear, stealing her words. He pinned her body even harder against the wall, and pressed his lips against hers. A light kiss at first; then he added some force and sucked stronger, and stronger, and stronger…

Until nothing was left.

Trafalgar Law felt the young woman's body slumping, and he stepped back, letting it fall to the ground. He wiped his lips with the back of his hand, glancing over the remote alley he managed to lure his victim in. It was empty.

Good.

His hunger was sated, and Law felt energy surging in his body. He was ready for today's patient.

Law put his spotted, soft hat back on his head, hunched into his warm, black coat and quickly walked away. It was such a cold winter day, and he had a lot of work to do. He wasn't known as the Surgeon of Death for doing nothing, after all.

The shopping center was Law's main hunting ground. It was always teeming with people, and he could choose whoever his heart desired at the moment. Just like in the shop.

Law was sitting on the bench inside the shopping center. Today he had one last job in this part of the Grand Line megalopolis before leaving for the next one. Police were already getting restless, and the crime lord who needed to be healed was on his last hours. He actually didn't have time for a long window shop.

The Surgeon gazed around the crowd bustling past him. His sharp eyes fell on a scrawny, black-haired boy in his late teens, wearing a red and white coat and, strangely enough, a straw hat on his head. The boy excitedly moved his hands while grinning widely and chatted with a long nosed teen.

A predatory smirk appeared on Law's face. What a lively one, and a cute one at that. He loved that kind of prey, they always satiated his hunger for longer.

The Surgeon followed both boys out of the shopping center, carefully avoiding all the cameras. The boys parted ways in front of an exit. The straw hatted teen hummed some kind of melody as he rounded the corner and walked into an empty shopping center's inner yard, probably taking a shortcut.

Law couldn't believe his luck. He was almost running late, but this kid made everything so easy for him. It seemed like fate itself pushed him into the Surgeon's hands.

"Hey, wait," Law called out.

The black-haired boy stopped and turned around to look at him. He stared at the stranger for a moment before a wide and happy smile appeared on his face. "Yeah?" he answered.

"Can you come with me for a bit?" Law asked.

"Eh?" The teen shoved a pinky into his nose, plucked out a booger and flicked it away. "Why?"

Law almost tripped over his own feet from surprise, while he walked over to him. He had found an odd one this time, for sure. Normally after such a question, youngsters started to get wary of him, but this kid…

"You know, it's not very polite to pick your nose in front of strangers," Law scolded him, a light smile tugging the edges of his mouth.

"Shishishishi," the teen chuckled. "Sorry, sorry! So, what do you want? Do you have something interesting to show me?"

The heck was wrong with this kid? He was more naïve than Law thought he'd be. "Yeah," Law replied with the friendliest smile he could muster. "Come here."

"Ohhhh!" The teen shouted in glee, eagerly following after the Surgeon of Death into the corner between two walls, hidden behind a truck. "So, what kind of interesting thing you gonna show me?" He asked as they reached their destination.

Law smirked. "This kind." He grabbed the teen by his shoulder, shoving him against the wall and pinning him down with a kiss.

He felt a sudden explosion of energy come into him as soon as his lips touched the youngster's. And it was unusually vibrant. Law definitely hunted a good one this time.

Feeling full, the Surgeon straightened up, licking his lips in a satisfaction. He never felt better before, this was simply amazing.

Suddenly it clicked. There was no body going slump, no thud when it hit the ground.

Law opened his eyes and was instantly frozen by the owlish obsidian eyes, gawking right at him. He stared back, in absolute bafflement. That never happened before. He was certainly full, but his victim was also still very much alive.

"AH!" The teen suddenly exclaimed. He pulled out a phone from his pocket and looked at the clock. "Yikes, Nami will kill me if I'm going to get late!" He touched Law's arm, the one that was still resting on his shoulder, and Law recoiled from him, letting him go. "It was really interesting, but I need to go now. I'm sorry! Next time show me more!" The teen flashed him a sunny grin before waving his hand. "Let's meet again! Bye for now!"

Just like that the straw hatted teen was gone. Law leaned against the wall behind him, rubbing his closed eyes. He was shocked to no end. What the hell happened?

It was a nice, pretty warm day for winter. Law was sitting on a bench on the edge of the park absorbed in thoughts. He absent-mindedly followed every person walking past him.

This one was too young, that one too old. That one looked like a good choice, but his hair wasn't black. The one over there was too tall, and the one next to him too fat. Law perked up when he spied a red and white coat in the crowd. Ah, no. That person didn't have a straw hat.

The Surgeon heaved a heavy sigh in exasperation. What the hell was wrong with him? From the moment when he kissed that straw hatted teen, he wasn't able to think about anything else. He wanted to know how he survived. Was it a fluke? Maybe the teen died later?

Somebody patted him on his shoulder. Law instantly turned his head to yell at the person who dared to interfere his musing.

Before he could say anything, warm hands cupped his face. His mind managed to register only the golden rim of the straw hat and a goofy grin before he was drawn into the kiss. The same vibrant sensation engulfed Law's body, making him feel like he emerged from the darkness and was showered by the warm sunshine for the first time in his life.

Law had to suppress an urge to grab the teen and leech onto his lips for longer when he eventually pulled back, and was now grinning at the Surgeon happily.

"I finally met you again!" The straw hatted boy exclaimed happily.

Law opened his mouth to speak, but nothing came to his mind. This whole situation was too obscure for him. It didn't make any sense! This straw hatted person didn't make any sense! His hat, his obsidian eyes, his small scar under one of them (it made him even cuter), his overflowing sweet and kind life-force… Nothing made sense about him!

"Lu-Luffy! Y-you kissed someone!"

Law tore his gaze from the teen's face and whipped his head to look at the owner of the unfamiliar female voice.

Three people were standing nearby and gawking at them, pure shock etched on their faces: the female who spoke had long orange colored hair, standing next to her was a green-haired bulky man with three earrings in one ear and a blond man with curly eyebrows and one eye hidden under his hair.

"Shishishishi, I guess I did!" Luffy stated proudly.

"But you… He… This…!" The young woman stuttered, unable to form a coherent sentence. Suddenly she flailed her arms and screamed, "This doesn't make any sense!"

Law had to nod, wholeheartedly agreeing with her.

The green-haired man just facepalmed. "Do you have rubber instead of brains, Luffy?" He groaned.

"Yeah, Luffy," the blonde said coolly, while lighting a cigarette, "if you're going to kiss a random person, go and kiss a beautiful lady, not a strange man sitting on the bench in the park."

"That's not the point here, Sanji!" The female screamed as she smacked him over his head.

"Guys, it's alright," the black-haired teen grinned at his friends, "he kissed me first!"

"He WHAT?!" Roared the orange-haired woman. "When?! How?!"

"Week ago when Usopp and I went to the shopping center. He said he had something interesting to show me and lead me into that corner. That's when he kissed me!" Luffy explained joyfully.

That kind of wording made Law look like a total pervert and he instantly was pressed by furious glares from all three of the teen's friends. He stood up from the bench and faced them with a small irritated scowl on his face, ready to defend himself if needed.

Luffy stepped between him and his friends. "Oi, don't be so mean! I liked that kiss!" He announced matter-of-factly.

Frustration radiated from the trio in an almost visible way, while Law couldn't do anything more than just stare at the straw hatted youth (his name was Luffy, his mind supplied) with confusion written all over his face.

"Okay…" the female squeezed out through clenched teeth. "At least introduce us then."

"Oh, right!" Luffy flashed another sunny grin. "This is my friends – Zoro, Nami and Sanji! Guys, this is…" he paused, tilting his head in puzzlement. He looked at Law. "Hey, what's your name?"

"You don't even know his name?!" Nami demanded.

Zoro facepalmed again, and Sanji regarded Law with open suspicion. Law couldn't blame them. Going by what he witnessed so far, dealing with this exuberant teen was an achievement worth of Olympic gold medal.

"Trafalgar Law," he introduced himself. Why he gave his true name, the Surgeon didn't have a clue. It would have been better to just flee from these people, but Law felt like his feet were glued to the ground.

"Right!" Luffy nodded. "So this is Tral– Trafg– Tralgaf–" with every try to pronounce his name, Luffy's eyebrows pulled together in frustration. "This is Traffy!" he finally declared with his dorky grin.

This time it was Law who groaned. "Just call me Law," he suggested.

"Nah, Traffy is fine," the teen replied, brushing of the suggestion. "I'm Monkey D. Luffy. Nice to meet you!"

Law's eyes widened. D? So this goofball was from the same cursed bloodline as him. Was that the reason why he survived not once, but twice?

"For the love of God, I can't take it anymore!" Nami stated, grabbing Luffy by the hand and dragging him away. "I need to tell you a thing or two, Luffy. Come with me!"

The blonde eyed Law one last time before running after the orange-haired woman. "Nami-swaaaan~! I also want to hear a thing or two from you!"

Zoro glared at Law before he also trailed after his friends. "Are you a moron?" He grunted to Sanji.

"EH? What did you say, marimo?!"

"I said you're a moron, curly eyebrow!"

"Want to fight, shitty kendo master?!"

"Bring it on, love café owner!"

Law was left standing alone, rendered speechless. He glanced at Luffy, and the teen caught his gaze. "See you next time, Traffy!" he yelled, grinning and waving his free hand.

Law stared after him till they all crossed the street and entered a café on the corner of it.

Trafalgar D. Water Law was not a stalker. Definitely not. There was no way that infamous Surgeon of Death stooped so low as to stalk someone. He was a hunter, but not a stalker. It just happened that the café where the straw hatted teen liked to hang out had a coffee of his taste. And that was the only reason why Law visited it every day for the past week. He certainly wasn't here for Luffy. It was a pure coincidence that the Surgeon sat at the darkest corner and secretly observed him all day long. He would not allow anyone to think otherwise.

"It's called stalking, you know."

Law's eyebrow twitched when he heard those words. He lifted his head to look at the saucy speaker. It was the blond friend of Luffy (Law barely remembered that his name was Sanji) who worked her as a waiter. Casually chewing on the toothpick and with a glint of insolence in his one visible blue eye, the man stared down at the seated Law.

The Surgeon leaned against his soft seat, not lowering his eyes from Sanji's, showing that he didn't feel threatened. "Do the waiters of this café offend every client? I'm here because I enjoy your coffee. It's hard to find one for my taste in this city," Law said, a confident smirk playing on his lips.

"I'm the owner," Sanji retorted, flicking his toothpick on the other side of his mouth, and glancing at the cup on Law's table. "Coffee you say?"

"Yeah, coffee," Law confirmed. What was this guy's problem? From the day one, he always ordered the same drink. Law also glanced at his cup. He was just a common client, enjoying his coff–

Law blinked once. Twice. Thrice. But the image didn't change.

Black tea was lazily twirling around in the cup before him.

"So, would you like to taste our coffee at least once?" The blond man teased. "Because you always order the black tea."

Law scowled, glaring at the cup. Dammit, he just pulled a rug from under himself. Had he really been ordering the black tea for the past week? In all honesty, he couldn't tell.

Sanji put a hand on the table and leaned towards him. "What's your game, stalker?" He asked in a dangerously low voice. "Luffy may be a naïve idiot, but he has family and friends who will risk their lives to keep him safe."

"I'm not playing any games," Law objected, picking up his cup of tea (which was already cold, he noted) and bringing it up to take a sip.

"Really?" The blond man straightened up and smirked. "So, you truthfully like our Luffy then?"

Law instantly choked on the tea and went into coughing fit. Sanji slapped him several times on the back to help him, with the same mischievous smile across his face. Once Law could breathe again, Sanji placed a hand on his shoulder, leaned closer again and said, "I'll just go and tell Luffy that you're here right now and you can deliver your feelings to him directly." He clapped Law over the shoulder to show his support, and left.

Law jumped up in a flash. He put on his coat and his hat, dropped money for the tea on the table and promptly walked to the exit.

It was embarrassing for Surgeon of Death to run away like that, but he was certainly not a stalker! He didn't care about that straw hatted teen! Not at all! Luffy can disapp–

"Traffy!"

Law froze with his hand on the door handle. As the light steps stopped right behind him, he clenched his teeth in frustration.

"Traffy?"

Law slowly turned around and instantly stiffened in his spot by meeting those owlish obsidian eyes. "Luffy-ya," he acknowledged. Luffy was standing way too close for his comfort.

A happy smile spread across the teen's face. "Sanji said you were looking for me. I didn't know you were here! I would have come to meet you much earlier! Are you leaving already? Why?"

Law glanced around him. It was good that there were not a lot of people in the café at this time of day. His eyes fell on the blonde and another of Luffy's friends (Zori? Zoro?), standing at the sidelines and watching him like hawks watch their prey.

"Come on, Traffy, join us!" The black-haired teen reached for his hand, but Law pulled it away.

"I…" Law mind was empty. He couldn't admit to himself that he was possibly attracted by this black-haired youth, so it was no way he could confess something like that loudly.

"Is it about the kiss?" With a small frown marring his face, Luffy asked, peering right into Surgeon's grey colored eyes with flecks of gold. "Do you need more?"

Law was taken aback. "…What?"

"Energy you take when you kiss. Do you need more?"

Law's eyes widened from shock. He couldn't believe what he just heard. Luffy KNEW? How? Why? What the hell?! And he was even okay with that?! "Why…?" Why are you offering more? Law wanted to ask, but his mouth suddenly dried out and his tongue refused to work. He was a killer, dammit!

"You're a D, right?" A goofy smile appeared on Luffy's face. "Ds come in pairs!" He shouted with glee.

Everyone in the café turned to look at them, and Law wanted nothing more but sink into the floor. He had no clue what the teen was talking about, and he also didn't remember ever telling him that he was actually from the D bloodline too.

A question came from Sanji. "What's that supposed to mean?"

"Oh, didn't I tell you about it, guys?" Luffy looked at the blonde. "My dad told me. Ds come in pairs to negate each other's powers." He faced Surgeon of Death again. "And Traffy is my other half!"

"Are you sure, Luffy?" This time Zoro asked.

"Yeah," the teen nodded firmly, not shifting his gaze from Law. "I understood the moment he kissed me the first time. I have too much energy, and Traffy lacks it. So, we share it!"

It was such a blunt explanation, that Law wanted to facepalm, and then vanish from the face of the Earth.

"Shishishishi. Ace used to set everything on fire quite often," Luffy continued in a light tone like he was speaking about the weather, not an ancient curse, "until he met Sabo, another D with the affinity to water. So, you see, Law, it's fate!"

A silence stretched between them. The words slowly sunk into Law's mind, and he was trying to comprehend them. The fact that Luffy called him by his true name helped him to focus on the importance of it, and how strong Luffy actually believed in what he was saying.

Suddenly Zoro groaned. "I'm out of here," he stated, turned around and walked away.

"Oi, marimo, you don't believe in fate, do you?" Sanji inquired, as he trailed after him, eventually leaving both raven heads alone.

"So, you kissed me because of that?" Law broke the silence, surprising even himself with his weak, insecure voice. He was the Surgeon of Death, dammit! He was a self-confident, arrogant bastard who could scare to death even the most evil criminals! But before those obsidian eyes and that cheeky smile Law was feeling like his whole world got thrown off its axis. "Because of fate?" He added quietly.

Luffy stared at him. "Partially, yeah, but mostly because…" he paused, letting his lips split into the biggest, sunniest grin Law had ever seen. "…I LIKE YOU SO MUCH!" He yelled at the top of his lungs before bursting into mirthful laughter.

As every person in the café started staring at them again, Law felt the warmth of blush creeping onto his cheeks and tips of his ears burning them red. He snuggled into his coat's collar; at the same time tugging his spotted hat down to hide his embarrassment. And just like that his fearsome and intimidating image as the Surgeon of Death puffed out of existence.

"Stop confessing in my place, you shitty lovebirds!" Rang an angry shout from the back of the café.

Luffy just laughed it off. He reached to grab Law's hand again, and flashed his usual sunny grin when the man didn't pull it away this time. "Come, Traffy!"

Law let Luffy drag him wherever he wanted. "Fate, huh?" he mumbled before a blissful smile curled on his lips.
