A/N: Hello! This is my first fanfic and is a crossover between Fate stay night by Type-Moon as well as Katekyo Hitman Reborn by Akira Amano. I don't own anything except the words I used to write this story with. Please, this is a story that will contain a lot of cursing as well as bloody fight scenes later on. If you will I would love to have feedback on my work such as spelling and grammar. If you don't like the way I write, such as the story being told or something else I would like it if you keep that part of your thoughts to yourself as that part don't concern me. Oh, and don't expect constant updates, this is just something I posted and while I do work on another chapter I might not poste it for a while. Sorry.

Enjoy!

Chapter 1: A Choice

She stared down at the amber liquid and took a sipe. The burn in her throat made her sight in content as her shoulders relaxed. She should have realised that it would have come to this. Every day it's always something. Either it's property damage, shouting, or trying to play peacemaker between her own and others famiglias. The paperwork and stress were killing her.

Tsunami thought back to the meeting with the Delas famiglia and had to fight back the urge to slam her head into the counter. They were a new up and coming organisation in the British underworld, not quite mafia but they had flames and Vongola could always use a new alliance. Besides, if she could make the organisation just a bit better by making them agree to some of the terms she set, she could feel just a bit better. They were incompetent and a bit on the stereotypical side of thing but at least she made it worth it. It's what made her going nowadays.

She loved her famiglia, she really did. But sometimes she just doesn't know what to do. Somewhere, deep in her mind under the darkest corner, she wondered if it was all real. Did they really see her as a friend? as a family?

She couldn't help but wonder.

What if Gokudera was only her friend because of Reborn? It would have been his big chance at getting into an influent famiglia. And didn't he say something like that before he tried to boob her the first time they meet? Yes, he did...

What if Yamamoto was only her friend because she saved him from committing suicide? Or maybe he felt that he was in debt to her?

Lambo has no one else to go to.

Hibari just wants to fight people, it was the only reason he joined.

Mukuro still has a great hatred for the mafia as a whole and only joined so he could get out of Vindice. Sometimes she catches the dark look in his eyes. And she knows that where Mukuro goes so will Chrome.

As for Sasagawa? Ever since a job had gone wrong his sister has done everything to make him quite. She can see it. How it tears him apart. He might just have been the only one that joined her not the famiglia, not the guilt, or any other motives. If he goes…

She shook her head, letting the brown locks dance in her face. No. No such thoughts.

She couldn't afford to. Yesterday was her 24 birthday. Meaning it's been a little over 10 years since she entered this crazy world. It's already too late. She has been a part of this for far too long. Everyone important already knows her face. If she were to make a run for it now they would drag her back, kicking and screaming. No questions asked. Probably making some kind of speech of her not taking it all seriously, about her responsibilities, about what's expected of her. They did it before.

She chuckled. Funny. Out of everyone in her generation in Vongola, she is probably the only one taking it seriously except the Varia. Xanxus has been a great help, more so than Reborn ever was. Not only did he help her to settle in but also showed her what quality was. He is probably the only one in Vongola she goes to for help and tries to impress. Kind of like a big brother. The kind that watches you from afar and let you do it on your own, only taking a steep in if needed. He does it differently from Sasagawa. Sure he tells her to call him 'Big brother' but had never really acted like it. She let out another sight.

"Rough week?"

"More like life. Can't remember the last time I had more than a week off to do what I want"

"Friends or job?"

"Both. God, I miss middle school. Can't believe it, really, I used to be bullied, a bad case of it too, back then that I always had a bruise or something. At least it was quiet. Back then no one had expectation from me. They actually let me live my life like I wanted. I could live with having a bad school life. It might not have been perfect. Far from it. But I could do what I wanted. I could go to the arcade whenever I wanted after school, read a book after finishing homework, heck even hobbies. Now it's just paperwork this paperwork that. Miss Sawada, you have a meeting this afternoon don't forget it. Miss Sawada, they're at it again. Miss Sawada. Miss SAWADA. I'm beginning to hate my own name to the point that I'm thinking about changing it."

"Damn… It sounds like you need a new job and friends"

"Ha! If it were that easy. I'm the heir to a family business and they'll never let me leave. Already running it."

"You know, everyone has a choice. The question isn't just what that choice is but how to make it happen." Tsunami stopped and stared at him with eyes too tired for someone so young.

"I've tried for 10 whole years not to get into the family business. First was saying no, they didn't listen. The second was running away, they found me two day later. The third was not trying to do anything. My 'tutor' didn't make it easy. He made my life hell on earth until I did as they said. My mother is an air-head that can't get her head out of the clouds, living in her little haven thinking everything is alright so I couldn't go to her. Dad? lost the title years ago when I found out he cheated on mom and had a son he didn't have the balls to say was his own. The kid didn't even know it himself! And they knew about each other! hack he saw more of my sperm donor than I ever will! And then he left our family alone for years with no end to work. Not even sending a card for anniversaries and birthdays on the right day. I did not have a choice in this matter. I had to do it whether I wanted to or not."

"Damn, almost sorry I said it. Sounds like you have tried about everything, sorry I can't help you"

"No worries, if you really want to you would give me the name of the whiskey"

"It's Highland Black, pretty popular even if it's a bit pricey"

Tsunami nodded. It was a good brand, not too strong with a fruity flavour, the English sure knew their stuff. She continued to drink for a bit before she decided to pay and leave.

Her tolerance for alcohol has gone up over the years and now she can drink a surprisingly good amount of it. A few things she picked up Xanxus during their drinking nights, or what he likes to call them ' bitching about work and trash', was to channel sun-flames into the kidney to speed up the process to break down the alcohol in the body. Making it so that she can both heal the damage from her heavy drinking and get sober in a matter of seconds. But it doesn't end there.

She practices it so much that she is almost a pro at it, or at least as much as she is ever going to get because of her mine flame. Something that Reborn forgot to teach her about. She could theoretically use all flames, the more well balanced they are the more she could use them. She got Lussuria to check how much of each flame she had and then asked the Varia for some training. Xanxus was pissed when he found out that no one had trained her properly. That she just kind of had to sink or swim.

Her flames were alright when they got the result;

Sky: 36%

Sun: 17%

Mist: 15%

Lightning: 12%

Rain: 11%

Cloud: 6%

Storm: 3%

Apparently getting one of the elements over 50% would result in getting the stereotypical type, like most of the Vongola Decimo guardians. Sure, their flames might get stronger but it's nearly impossible to use any of the other elements. Her storm and cloud were a so low that she would probably never get the chance to use them unless she literally trains them all day for a century, each. Any flame under 10% is impossible to master unless you dedicate your life to them. She didn't want that and instead chose to train up her other flames. She is practically a master with her sun-flames with how much she uses them to make sure she stays in health and uses them to cheat and not get a hangover. Almost anything except the lethal she could heal to a certain degree, it will still scar but she can live with that as long as she can get to a hospital in time.

The fact that her mist-flames were so high had surprised her. It wasn't something she had used much until Mammon had taken to teach her something. Like changing her appearance. It's damned scary who much she looked like Primo as a blonde and blue-eyed girl. But it was fun. Tsunami used it to experiment with different styles and to escape her famiglia when she needed some time alone. The fact that no one notices an extra maid on one seen before makes her want to strangle them. This is why she makes the Varia clean house at least once every half a year without telling anyone except her guardians. It's a handy ability and one she is abusing the shit out of.

Her rain-flames are surprisingly something she has been using a lot unconscious in order to deal with being a mafia donna. In meetings, she uses it on herself to keep from snapping at her guardians and even during that time of the month. Every time she is irritated or angry she channels a bit of it into her system in order to stay calm. Boy did the Varia freak out when they found out about it. To them, she was practically a ticking bomb just waiting to go off. Suppressing emotions are never a good idea, to keep them bottled up and never releasing them takes a lot out of a person.

They locked her into a steel and concrete bunker full of things to break and wouldn't let her out until the next day. After taking one look at the room the next day an unspoken agreement was made. Never piss off Tsunami. The room was trashed. The walled was cracked with big chunks of it missing and blasting marks were everywhere. What little that was left of the training robot made more than a few turns white and in the middle of all the rubble was a smiling Tsunami looking a lot more relaxed and happy.

Lighting was expected. How many times has she tried to save one of her friends? It wasn't fun to learn that one, even if it makes her dodge and fight better than ever. And take a punch. Seriously, shooting electricity through your hand while punching someone could literally kill a normal human. And isn't that a depressing thought? Can't even be called a normal human now, can she?

The other guardians still can't figure out why all the Varia agents were treating their sky as is she where a hungry tigress waiting to bite their heads off. It was surprisingly amusing to watch. Damn, Xanxus must be rubbing off on her.

Today she doesn't use it like that as it will just end with her bottling up all of her emotions. In fact, she was told by Lussuria to not use it at all in fear of her making the same mistakes twice.

Tsunami let out a sight in the cold air. She missed Japan. She missed her ho… But she didn't have one, did she? Italy will never be home to her. The most she feels at home with are the officers at Varia and even that are just barely. They are great friends, family even in some aspects but… It's just not what she is looking for. Vongola mansion just feels like her workplace where she is slowly digging her own grave trying to ignore the chaos around her. Her own childhood home wasn't much better. How many memories did she have of being bullied? Teased? Of being someone's punching bag? Too many.

A gunshot rang through the air, immediately bringing her out of thought and into combat mode. Her sun-flames already working on breaking down the alcohol. It came from the ally right next to her. There were three people. A woman in a business suit on the grown holding her side, a man on the ground with a gun in his hand and a hole through his chest, and…

"A man wearing blue battle armour?" In all honesty, it looked like spandex but she wasn't going to say that. And She really shouldn't have said that out loud as they both turned to her. The man in blue looking more hostile than the woman.

"Should I call the police, hospital or someone else?" The woman didn't strike her as your typical civilian. She was too calm and it wasn't the shock. She could clearly feel the pain if her face was anything to go by and there was no surprise either. Plus, she had a battle-armoured guy before her and didn't even react to it. That and her intuition told her to ask.

"Don't bother. He hit an artery, I'll be dead before anyone could even arrive." The woman's voice held an Irish accent to it and spoke with such calm Tsunami had to wonder if she were a latent rain.

"Don't say that. Argh! If I had just warned you in time this wouldn't have happened. It's over before it even begins. Damn, I hate my luck." The blue man also had an Irish accent and let his hands up in frustration. Tsunami sat down next to the woman prayed her hands away from the wound.

"Hey! what do you think you're doing!"

"Making it painless. It's the least I can do, it will also give you a few minutes but not much." Tsunami began to channel her sun-flames into the wound. The effect was instant. The woman relaxed and smiled at her while the man seemed to get the idea that she wouldn't hurt her. The woman, not beautiful or cute but rather pretty. With her shoulder length, purple hair and suit gave her a professional look.

"Thanks, but if you don't mind me asking. Why are you doing this?"

Tsunami gave the woman a blank look. Why did she help her? Her caring nature had been broken down some time ago from the harsh life she lives. Not quite sure which is friend and foe. That was something she had to learn fast. She had to adapt. Because while Vongola might have wanted to go away from it's bloodstained past the rest of the mafia did not. There was little she could do about it more than trying to negotiate with the other famiglias. Going to war with one was just screaming for Vindice to come and get them. She had to change who she was in order to not break drown.

"Because I want to" The answer didn't seem to satisfy either of them judging by their faces. Tsunami just ignored them. It's the truth. To save someone life, even like this, knowing that they would parish was enough.

"You know this isn't really going to save your life, only give you a few more moments. You shouldn't waste them" The woman shook her head before catching the blue man eyes. She really needed to get their names.

"Sorry Lancer, and no it's not your fault for me being in this mess. If anything it's mine. I shouldn't have underestimated him and have you back down. I'm a fool and let my pride get the better of me. Besides, it's you that's going to miss out on that wish. I already got to meet my hero, what more could I want?" The woman smiled at Lancer before she began to cough up some blood. "Do me a favour and find a new master, that way you at least get to have some action." Tsunami raised and brow but didn't comment. This wasn't her moment to interrupt with stupid questions.

"Oh? And where do you suppose that I will find a master on such a short notice?" Almost immediately he facepalms. "Don't answer."

The woman chuckled and Tsunami had to resist asking what they were talking about.

"Miss, what's your name?" Tsunami looked into the brown eyes of the woman before her. She looked to be about herown age. Maybe a year younger or older, she couldn't tell.

"Tsunami Sawada, yours?"

"Bazett Fraga McRemitz… Would you mind doing me a favour?" She looked at Bazett, not really knowing what to say.

"Depends, care to tell me?"

"What would you say about participating in a tournament where the winner is granted a wish, doesn't matter what it is, it will do it. If you accept you're going to be facing several opponents in life or death battle together with Lancer here. I won't lie to you, you will probably not survive unscratched. If the competition is brutal enough, death."

Tsunami stared at her. It was a rather blunt way of saying she would be joining in on a battle royal. And a wish. It was not the most outlandish she has ever heard or done. But it was almost too good to be true. She could wish to live a normal life. To make everyone forget about her and start over. To leave this bloody and depressing world. Heck, she could wish to go back in time and relive her life from her time as a five-year-old before her idiota of a sperm donor sealed her. She didn't care if she died. Tsunami was already dying on the inside. Fighting she could do. It's what she has been doing for as long as she can remember. Kill? Something she would like to avoid but had to in several different situations. And that's what killed her. She wasn't made to kill. Their faces hunt her in her dreams. She remembers every last one of them. Her family? wouldn't miss her. What did she get to lose?

"Alright, where do I sign up." Bazett looked a bit surprised, probably not expecting a positive answer.

"With her, as I don't think you want to want to transplant her markings onto your skin we'll have to do it the old-fashioned way." She looked at the blue man taking him in. He was handsome. Sharp face, irritatingly good-looking smirk, and blood red eyes. Damn.

"Well, how do I do it?" He nodded his head to Bazett who took Tsunami's hand from the wound and began to say mumble something. Tsunami cut out the flow of sun-flames and looked at the dying woman. It sounded like a prayer. A sharp pain came on the neck and her flames were pulled in the direction of the blue man and embraced him. The pain was gone as quickly as it came but the flames seemed to linger. There was a barely noticeable drain on them but it was so small she wouldn't have noticed it if she hadn't been looking for it.

"Done" Tsunami took back her hand and put it where she had felt the pain. There wasn't anything there and if there was she didn't feel it. What had she done? "Now all you ...need to.. do is to go to... to Fuyuki in Japan." Bazett's breathing was becoming more irregular. There was nothing Tsunami could do. Before she knew it, Bazett was dead. There was silence. Tsunami closed the woman's eyes before she turned to the man, Lancer.

"Any idea on what to do now? Do you know her family?" Lancer shook his head. He didn't seem pleased with it.

"No, never meet them. But I do know where we can leave her. Her apartment isn't that far, from where I can make a call to them on her phone." He took up the corp and began to move. Fast. Tsunami thought as she followed him, doing her best to jump from roof to roof.

Normally it wouldn't be much of a problem but the way she dressed made it more difficult. Running in stilettos and business suit, with a skirt to just above the knees and not trousers and trainees, was not an easy fate. Damned Reborn. Why did he have to make a makeover on her and burn all her old clothes? She still can't use make-up and even if she could walk in these shoes that don't mean she likes them. The same goes for the suit. When she gets to Japan she's getting some new cloth. Tsunami doesn't care if they aren't trendy or something like that, she likes comfy and hasn't been able to get into a pair of sweatpants for ages. Skirts and dresses just won't do. Besides who cares what she looks like? Isn't practical better than accessories?

And shouldn't Reborn know this? He might be a dress snob but he really? Sure there are some females assassin and hit-women who wear them but… Really!

Finally, they made it to the what she could only guess was Bazett's apartment. It wasn't big and clearly just something she owned to sleep in. It's not her home. There are no pictures and little of what one could call personal belongings. Only the necessity. Some furniture, clothes, kitchen equipment, and random thing. Tsunami walked over to the sink to wash away the blood from her hands and neck Before she took off her shoes. They were killing her. Lancer had found the phone and began to make the call. She looked at Bazett over on the bed. She looked peaceful. Like she wasn't in pain when it happened, and the relief in which she was after she had accepted to play the part of this tournament.

"Maybe I'll finally be able to control my life again"

"What was that?" She hadn't noticed that she spoke it out loud. She locked eyes with him.

"Nothing much, just rambling" He didn't seem to believe her but didn't ask any further. Tsunami began to massage her aching foot, trying to not listen to what was said on the phone. They clearly weren't happy, but who would? After a couple of minutes, Lancer ended the call.

"Well, they are going to get her and while they aren't happy to find out Bazett that died before even entering the tournament officially, they appreciate us giving them her body back and giving her a pain-free death."

"Right, good to hear… So will you tell me more about this tournament while we make it back to my hotel? I am not backing out, mind you, I just want more facts to work with. And what's about this drain?" His smirk was going to get old and fast. At least it's not as annoying as Reborn after he got back to his adult size.

"Sure. It's called the Holy Grail War where seven mages summon a servant each and go battle royal against each other. The servants are people from the past who's legends still lives on until this day and gets put into a class which grants them some form of bost. The classes are, Saber, Archer, Lancer, Rider, Berserker, Assassin and Caster. The classes are pretty self-explaining. The drain? I'm not exactly alive anymore and in order to keep me here for the war, someone needs to supply me with mana. And let me tell you that you have quite some power there, I'm pretty sure that I could use my noble phantasm at least four times before your reserve is going to get low" Tsunami stared at him with wide eyes. He wasn't lying. Her intuition has been improving over the years to the point that she is basically a walking lie detector.

Mages? As in magic? Legends coming back from the dead? She sights. It wouldn't be the weirdest thing to have happened to her. Everything from travelling to the future and creating a paradox, to having a baby tutor her in how to be the future Donna in a mafia that has flames shooting out of their heads. Really, she doesn't do normally.

"Right. Well, I'm guessing you're a lancer then? And if you don't mind me asking, what's your real name" She jumped from roof to roof, getting closer to the hotel she was staying at. It was nothing too grand. She could have that all the time at the mansion. She really missed the simple things in life.

Looking at the basically living legend, she wondered how she was going to get him inside without getting any weird looks. Well, she could turn him invincible it would be too hard, and her flames were not strong enough to keep it going for too long. Jumping down to the ally she turned to Lancer who was no longer there.

"Lancer?" Tsunami turned around to look at where she knew he was but found nothing. What? Taking a few steps forward to where she could feel him she stared at the spot. Suddenly he materialised from nowhere in a blue light looking troubled.

"How did you do that?" She blinked. Did what? Her expression must have said it because he continued. "How did you know where I was? Nobody's supposed to know where I am in spirit form, not even my own master..."

"You mean when you disappeared? Can't say I know why but my guess is that it's because of my intuition." Lancer gave her a look of pure disbelief. "Don't ask me. It was never explained how it works or why it's in my family. All I know about it is that it will warn me about danger and tell me if someone is lying. Or if it feels like I have to do something it will usually turn out good."

"... I hate fishing, am terrified of my mentor, and have the good luck"

"Lie, truth, lie"

The look of pure disbelieve almost made her laugh. Tsunami turned around and walked into the hotel. Knowing she didn't have to worry about Lancer now that she knew he could turn into what was apparently a spirit. When she, or rather they, entered her room and Lancer became visible.

He stared at her some more before flipping down on the sofa. Tsunami didn't know what to do so she took her nightgown and walked into the bathroom. She needed some time to think. Turning on the shower she stripped down and walked into the steaming water. This night was not going as she had expected. After meeting with the Delas famiglia and working out some deals she just wanted a quiet night out and get drunk. None of her guardians was here, they were either back in Italy or out on an assignment. This wasn't something important, she could have just skipped out on it and given it to someone else. But she needed to get out.

And now? She had the perfect opportunity to get away. She could take a month off. Just make a call to her secretary and tell her she was taking a vacation somewhere. Not telling her where to, take her backup card and use her mist-flames and nobody would find her for a while. At least until they called in the Varia to track her down.

She really owed Mammon for teaching her how to create fake identities and bank accounts. And maybe text Xanxus so that he wouldn't rant about it when, if, she came back. Smiling she walked out of the shower and began to take on her night cloth. When she was about to walk out stopped as she walked past the mirror.

There was something on her neck. Creating a hand mirror she turned around and saw a tattoo. Her eyes widened. It was a red tribal tattoo which almost looked like a fire, elegantly following up her neck. It was beautiful.

"Hey! you alright?" Tsunami shook her head and walked out, making the mirror disappear on the way.

"I don't know. There is a tattoo on my neck."

"Huh? Let me see." He rose up and placed a hand on her head, angling it so that he could see. His touch sent a row of electricity down her spine. Damn. When was the last time she got laid? She knew the answer. Nearly two years ago. After Gokudera found out about her 'boyfriend' he almost killed him. He wasn't so much a boyfriend as a one night stand but he got the message out clear. She didn't want to risk it with how they reacted.

"Nothing wrong, this is just the mark which marks you as a master in the war. It's supposed to appear somewhere on the body."

"Is there more to them?"

"They will be able to give you three absolute orders that could even bend the world itself to them. You could order me to defeat an opponent and I would get a power-up for an attack. You could order me to defend you and I would be at your side in an instant even if I were on the other side of the earth. You could order me to do something I don't want to do like force me to commit suicide. Ordering someone using that mark gives you absolute power." In the end, Tsunami looked like a ghost. Was she going to have that much power over someone else? Sure, the mafia might have changed her and broken her moral bits by bits. But this? No. She wasn't going to use it if she didn't have to. She could see that some of the effects could be good... But still...

"What happens when they are all used up?" She was almost afraid to ask.

"It will be over… For me that is. After you use them all up I'll disappear and you're out of the war." She almost hit him for that one.

"Alright, is there something more I should know?"

"Yeah, when we get to the city we need to go to the church. They are to overseers of the war and the one that makes up all the excuses for the damages that's going to take place. And when I'm out, you either go to the church to seek protection until the war is over or try to get the hell away from there as the other will probably try to kill you."

"Right... So it looked like I'm going to need to need the big guns for this I take it?"

Lancer's grin irritated her to no end. She sighed and took out her computer. She had work to do, and for once it wasn't the mind-numbing one. But the fun once that Lussuria taught her for undercover. She began to type.

"Right. So if we are going to be partners for however long this battle royal is going to be, we need to sort things through. First, how strong are you guys? Servants I believed you call it?"

"Yes, and I would say that its varieties. Someone could probably split a mountain depending on their stats."

Tsunami paled. That was some fire armour. Nothing like she had ever experienced. She would only get in the way and be more of a hidden for him if that was the case. So what could she do? Sniper from behind wasn't her style, and she wasn't sure if that would even hurt a servant. Maybe…

"How much would it take to hurt a servant? If we take firepower here, do you know what a bazooka is? And if so could it slow them down?"

Lancer looked at her somewhat surprised before he began to think.

"It might surprise and slow someone down, but I don't know if it will kill us. If so you would need something really big. Why are you asking? And how would you even get something like that? From my knowledge, magi don't use mundane weapons "

"Well, I have my ways" Tsunami smirked at him while she began to type a message to the R&D facility to see if they had any new toys they needed testing. There was a lot she needed to do.

"Right. We are going to make a quick stop in Italy and then we'll head over to Japan after I get some things. Is that alright with you?"

"Sure" Lancer didn't look overly joyed at it but didn't complain. She threw a glance at the clock. 02:34. Her flight was expected to go at 9 o'clock and she could use a few hours of sleep. She put away the computer and set her phone on an alarm.

"I don't know if you need to sleep or even eat. And as there is only one bed here you can join me if you want" When he smiled at her she almost regretted it. Almost.
