S'up homies! Hiyarrr- I decided to finally write and upload this story for you- even though Bite Me Sensei is still being written. I thought up the idea for this years ago but decided to change it to a ShizNat story because I just LOVE them and thought they worked with the original idea so well.

Apologies in advance for any confusion that may be encountered. Just as a heads-up Natsuki works as the Perfect assassin by Searrs Foundation under the codename Duran.

Hope you like it- it was a pain in the bum to write and reviews will be greatly appreciated.

Love as always,

Chapter 1: Hungry like the Wolf.

It was eerie. The silence was unbearable as the young agent stealthily made her way through the damp, lush and dense forest. Her emerald eyes scanned the area, her ears were on the alert and every hair on the back of the young girl's neck was stood on end.

Come out, come out wherever you are!

Duran smirked as those childish words rang in her ears- recalling the many times she would chant it during a game of hide-and-seek. No-one could hide from her. Her senses were unparalleled among the minions of the Searrs Foundation... well apart from Miyu and the damn girl wasn't in all fairness Human! Duran smiled as she caught sight of her target which appeared to be an underground bunker with 4 men guarding- armed with Heckler and Koch MG4's.

Found you!

"Agent Duran: What's your status?" The monotonous tone of Miyu's voice didn't even break the agent's concentration. "I'm at the bunker. There are 4 guards with MG4's- this should be interesting." Duran smirked as she silently hoped that maybe this was going to be harder than it looked- the young woman was becoming increasingly restless and frustrated with her employers for handing her missions a level-C agent could do let alone a Level-A as herself. Duran lined up her sights, she reached for the smoke bomb on her belt- flinging it to the left in order to create a diversion whilst in a flash successfully managed to take out two of the four guards.

"2 down. Only 2 more to go." Duran waited as another guard came into sight before she pulled the trigger again and the guard fell to the ground. By now the last remaining guard was getting panicky as he waited for the other guards to return- he had seen the bomb go off and had sent two of them to investigate and when they hadn't returned- he was unsettling. He knew he couldn't abandon his post but he hated the feeling of powerlessness as he waited for whatever entity to show themselves. The hairs on his arms pricked up as he heard the noise of rustling from within the green- he couldn't take the suspense anymore as he automatically opened fire until the very last round was gone- as was the noise.

He timidly jogged over to the bush when out of no-where someone or something jumped on him- wrapping their hands around his throat. The man wriggled as he gasped for breath- each one becoming more laboured and short as the last.

Duran could feel the man gradually losing strength as he desperately tried to claw her hands from his oesophagus. After a minute of struggling, the man's hands fell limp at his side as his eyes closed- slipping into unconsciousness. Duran smiled in satisfaction as she checked the man's belt- spotting the Access card needed to get through the gates. Even with her night vision goggles she couldn't spot anymore guards- and that worried her slightly.

Where the hell are they? They must have noticed something by now?

Duran ran over to control panel- swiping the lackey's key card through the slot- breathing a small smile of relief as the words "ACCESS GRANTED" flashed in amber letters across the screen. Her mind flashed back to the de-briefing before where the plan of the building had been implanted in her memory- literally. Duran frowned as she could still feel the throbbing pain in the back of her head where that damned android had touched her- thus her instructions were embedded in her mind.

Follow the corridor for 300 yards. At the end of the corridor turn right, then turn left into another block identical to the one you have just been through. Turn left again- this will disorientate you so be careful. You will then reach sector B-4- the room with the target is in that sector- we do not know which. Be careful.

Duran followed her instructions to the letter- she even became disorientated after following each corridor and the bunker itself wasn't that big- the poor excuses for guards were easy enough to take out. Each block she went through was as identical as the next- until she reached Sector B-4. Outside the entrance to the block were 3 men playing some sort of card game- laughing like the Jackasses they looked to be. Duran rolled her eyes, leaning against the wall that she was hiding behind she pulled out her trusty pair of Kahr P380's- making sure she was locked and loaded... in case she wanted to use them.

3...2...1...GO! "Hey, can any of you fella's point a girl in the direction of the bathroom?" Duran flicked her hair back with her right hand as she rested her left on her hip- mustering up the sexiest pose she could. She had seen Agent Zhang do it the last time she was forced to work with her on a mission and had been pleasantly surprised to find it made every man turn to putty in her hands. She felt extremely uncomfortable but if Nao could make it work- she sure could. I'm sure Nao's killing herself over this.

"Er... sure gorgeous... please follow me." The blond Jackass winked at his fellow guards as he walked in front of the young woman- and as he held the door open for her- he couldn't resist in sneaking a peak at her behind. Eventually the two reached another door and the blond guard gestured for the strikingly beautiful bluenette to go in "Ladies first."

"As opposed to..." Duran raised an eyebrow- trying desperately hard not to kick the guy's ass then and there. She wanted to have a bit of fun first- she felt entitled to it after all! "Unisex darlin'...it's all the rage here!" he said with a wink. At that moment, Duran dragged the guard into the bathroom by his shirt lapels and pressed him against the door forcibly. "You sure are good at taking hints." Duran took hold of both of his hands and placed them on her hips before whispering close to the guard's ear.

"You like what you feel huh? Tell me do you like this?" Duran smirked as the guard's face went from one of extreme pleasure to one of utter horror as he felt both handguns being pressed into his groin. "You see my trigger fingers have been fairly twitchy lately- you give me what I want and I may just let you keep whatever makes you a man. Got it?" The blond guard nodded his head profusely "You know what I'm after correct?"

"I...I do." The blond guard swallowed, having two guns pointing at his manhood made him tremble with fear "Third door on the right."

Duran shook her head in disbelief- they weren't making it very hard for her. What are they playing at? At least take me seriously goddamn it! "Tell you what why don't we go on a little walk?" Duran pulled the guard roughly out of the bathroom after checking if the coast was clear- clutching the man's arm with one hand whilst the other held a gun to his head.

"Keep moving." She ordered in a deep and menacing voice that proved that she meant business. "When we get to your buddies- greet them as if everything is normal is that understood?" Duran could hear the blond mutter some sort of curse word under his breath, so she took her gun and it met with the man's skull causing the man to falter in his steps. "I said is that understood jackass? Nod vigorously. Good now get moving."

Duran stood behind the taller man who barged his way through the doors where his friends were waiting for him- making perfectly sure that she was hidden behind him. "Ah Tate-kun, have fun?" the dark-haired guard with a cross shaped scar asked without taking his eyes off of his hand of cards. Tate chuckled nervously- tensing up as he felt the gun dig deeper into the back of his neck "H-hey guys!" he gave the two a small smile and a wave.

"Everything ship-shape Tate? Sit your ass down, I'm just about to take all of Kazuya-kun's earnings." The guard named Takeda said with such confidence. "Well? Don't just stand there like a stiff- sit down."

"He would if he could gentlemen." A female voice came from behind Tate as suddenly a leg wrapped around the blonds' left leg causing his knee to buckle and he fell onto the ground.

"YOU?" Both of the remaining guards jumped from their seats, taking their guns out from their holsters and aiming at the blue-haired beauty they had seen leaving with Tate. Duran rolled her eyes, pointing one gun at Tate's head whilst the other was directed at Takeda- "You have something that belongs to me and I want it now. If it's not within my hands within the next 30 seconds my trigger finger's going to be really happy. GO." Duran herded the men into the next corridor where the guard called Kazuya took the set of keys from his utility belt- desperately trying to find the right key. Just as he was about to put the key into the lock the door vanished, as did the entire building- much to their confusion.

What the hell? Suddenly the room went back to bright blue walls- leaving the agent and the three guards utterly bewildered. Suddenly a deep voice rang through the arena as a blond haired man in a suit entered. "What the hell Smith? I was close!" Duran growled as she released Tate and placed her guns back into their holsters.

"Sorry about the intrusion Agent Duran- an issue of grave importance has arisen. Miyu – suspend simulation and get your team in here to take the bodies to the sleeping bay." As soon as he had finished speaking, the light blue-haired robot made her way into the arena- her face as solemn and stoic as ever- and she and her men dragged the sleeping bodies of the guards the Duran had taken out.

"What's going on Miyu?" Duran heard Takeda ask the robot timidly. "The leader of our Tokyo base Kuga Yoshi has been assassinated by the First District along with five other high-ranking officials in that district. Kuga-san! I need you to come with us." Duran felt her heartbeat race as she knew that whatever needed to be discussed was serious- no-one ever called her by her last name unless it was really urgent. The agent nodded as she followed Miyu and Smith out of the arena into a huge soundproofed office. Her mind was racing and her thoughts were scrambled and all over the place.

"I guess you understand why we have called you here Natsuki? There will be no need for silly codenames- this is serious business- I hope you understand the severity of what is to be discussed." Natsuki nodded whilst clenching her jaw. "Your father's assassination has come at a critical time Natsuki- it now gives us the perfect opportunity to completely annihilate the First District bastards. An eye for an eye yes?" Smith raised an eyebrow as he saw the younger girl before him stand a little straighter- he knew exactly what was going through her mind now. After all these years of training, planning and dreaming- the plan was to be put into motion.

"You're asking me to do what exactly?" Natsuki folded her arms across her chest- silently praying to Kami that the next words to come from that idiot Smith were going to be the one's she'd waited for years to hear. Smith couldn't keep the smirk off of his face. "For years Natsuki you have been trained and moulded to be our greatest weapon- the Ultimate Weapon! Your orders are simple: you will infiltrate the ranks of the First District and work your way up in order to gain a position where you will be able to successfully 'bite the head off the snake' so to speak. In addition to that- the leader has two daughters. One of which you are to dispose of and the other is to be captured and brought back to us. When you return after your rec break you will find all necessary documents. You will also have a driver to take you to the airport at 7 for a flight to Japan at 9. I wish you the best of luck Princess." Smith rose to his feet and bowed at the woman in front of him who only gave a small nod. She had always hated the man who had been the father figure in her life whilst her own was across the sea in Japan. Now that man was dead- Natsuki now had everything she had ever dreamed of- the opportunity for exacting her revenge.

Natsuki made her way over to the mess hall where she was instantly pounced on by a short, spiky-haired girl named Mikoto. "Yeah, thanks Mikoto. Where's your owner?" Natsuki brushed the young girl aside as she scanned the room for her red-haired friend Mai- however the girl was nowhere in sight.

"KUGA NATSUKI YOU ARE IN TROUBLE!" A high-pitched yell rang through the room as a busty redhead ran towards the raven-haired agent before tackling her to the ground- well she had attempted to! Natsuki smiled as she successfully managed to dodge Mai's attack which sent the girl flying into the counter. "What have I done now?" Natsuki held out her hand to the girl who readily accepted and was pulled to her feet.

"Ok first of all why did you have to use Nao's seduction technique on MY boyfriend during training? Two- why did Sakumisu and his lackeys break into our apartment when I was in the shower? THREE- why do I get the feeling that- once again- you aren't telling me something? I'm supposed to be your friend Natsuki or am I just a general inconvenience to you?"

Natsuki could tell that the redhead was indeed pissed about something "Are you sure you want me to answer that Mai? And enough of the questions ok- you're doing my head in." Natsuki grabbed a plate and tried to brush past Mai who grabbed on to Natsuki's arm. "Mai- if you know what's best for you I would let go of my arm." Natsuki hissed with so much venom in her malicious voice that the girl had no choice but to comply. There was a reason why Natsuki was known as the Ultimate Weapon, she had been brought up by Searrs who had thrust a gun into her hand from the word 'go'- the girl was lethal and not to be messed with.

"Tell me or don't tell me I don't care anymore Natsuki. I don't get why you insist on driving everyone away- you are a good person Natsuki." Natsuki's eyes widened in disbelief over what she had just heard- how could anyone like me be dubbed a good person? Natsuki seized Mai's arms and pressed her against the counter "How can you call me a good person Mai? I've killed so many people I don't even deserve to be labelled a person- I'm a monster Mai. Anyone who gets remotely close to me always ends up hurt."

Mai trembled at the emotion in Natsuki's voice- it made her feel uncomfortable as it was something that no-one had ever witnessed. Despite the fact that Miyu was completely made of metal thus was an android- void of any emotion- many people within Searrs were utterly convinced that Natsuki was one too. It was a rare occasion when the agent would eventually reveal herself to be human.

"Ok Natsuki. Ok. Then I'm a monster too- we all are. Look I don't know what's going on- I don't know why people are running around the place like headless chickens but... I do know that I care about you alright? You may be a monster but I know that you care when you kill. You don't sleep the night after a mission. You pace up and down and you have nightmares too. That shows that you ARE human Natsuki- not a weapon like you've lived your life to be but a human!" Mai smiled warmly at Natsuki who responded with a small smile and a gentle touch on Mai's shoulder.

"Thanks Mai. You've always been good to me- even when I bit your head off all the time." Mai laughed as Natsuki flashed an apologetic smile. Natsuki cringed as she saw the smile completely disappear from her friend's face before turning into a look of hurt and sadness. Natsuki wasn't the only one who noticed as Mikoto tugged on the older girl's sleeve "Mai? Natsuki what's wrong with Mai?"

"You're saying goodbye aren't you?" Natsuki was taken back the amount of anger and hurt in the girl's voice- yet she hung her head low unable to hide her guilt as she knew Mai was correct. Mai shook her head in disbelief "Another thing you weren't planning on telling me wasn't it? I'm sick of the secrets Natsuki- tell me what's going on."

Natsuki took a deep breath and pondered over whether she should tell Mai about the latest mission... or the fact that the reason why people were so on edge right now was due to her. Natsuki quickly grabbed hold of Mai's wrist and pulled her over to a more secluded area- Searrs always had their spies and most of them had their eyes on their precious Natsuki. "Mai..." She struggled to find the words- she rarely ever opened up to anyone about anything... she remained a complete enigma. "I am leaving, I don't know for how long and I'm pretty sure I'm not supposed to tell you that anyway. The leader of the Tokyo branch was killed earlier today by the First District." Mai's face was one of which under any other circumstance would have been the butt of jokes for weeks to come.

"Natsuki isn't he... wasn't he your father?" Natsuki nodded as she looked down at the ground in front of her. There was nothing interesting down there but Natsuki couldn't bring herself to risk seeing Mai's reaction. "They are sending me over there to get rid of the First's leader and his daughters- some kind of shitty 'eye for an eye' thing Smith said."

"I can't believe you're going back to Japan already- I thought they said you could take some time off before this?" Natsuki raised her head "Mai this is everything I've ever wanted. Every step I have taken, every enemy I have killed, I have killed to bring myself closer to this. I was made for this." Natsuki said it with such conviction that it almost scared the violet eyed Level-B agent- Natsuki always carried out each task with such passion and it was now apparent to Mai what motivated her friend.

"Ok, I get it. Just promise me that you'll take care of yourself out there ok?" Mai smiled as Natsuki nodded- it had always been a bit of an 'inside-joke' that they would promise the other to be safe when they knew there was every chance of one of them coming back in a body-bag. Still- tradition was tradition and they had started it 5 years ago at the tender age of 14 respectively.

"Take care Mai. Tell the others I said goodbye- you know I hate that mushy stuff. Erm...Oh and if Nao bitches about me stealing her technique... tell her it sucks and she can keep it."

Natsuki smiled warmly at her friend- they had known each other going on 10 years yet she still felt awkward at the thought of showing any emotion or vulnerability. Mai knew she couldn't keep it in any longer- after all how long would it be before she would see Natsuki again? She wrapped her arms around Natsuki's shoulders and pulled the girl into a tight embrace. Eventually both girls stepped away from each other and Natsuki turned around to run back to the apartment that they had shared. "See you Tokiha" she yelled over her shoulder.

Almost as a whisper Mai replied- watching her best friend run off into the distance. "See you... Natsuki-chan."

A/N: Right so here's the first chapter done, hope you liked it. Shizuru will be introduced soon I promise but the next chapter will be more focused on Natsuki and her past.

Love love.
