Co-Author's Notes: Hello!

..

'You don't have a choice in this matter. Someone re-created the Holy Grail War ritual in this city and all of us are already involved in this!' explained the black-haired girl dressed in red unhappily, glaring at the others who were with her right now. It was obvious that the girl was frustrated.

Who wouldn't be if they found themselves in the middle of a war zone with naïve individuals who thought that their powers, as amazing as it was to normal individuals, would help them stop this bloody war?

'The simple fact is, even if this is happening in Academy City, where magic users like ourselves are hard pressed to use our magic it's still dangerous. No, it simply makes it even more dangerous! If they can't achieve their goals through straight confrontation, they would use more subtle and thus more dangerous methods to attack one another. They have no qualms in taking human lives and if all of you are stupid enough to try and get involved or to even think about solving the problem by apprehending them, you might as well be preparing for your own funeral!'

Tohsaka Rin, the magus girl in question, was about to continue when her companion, disciple and lover, Emiya Shirou placed one hand on her shoulder to get her to stop.

'Stop, Tohsaka.'

It had been a while since Shirou called her by her family name, one that he would only do if he was either upset or serious. Rin paused before looking back at him, and when her blue eyes met with his steely ones, Rin paused and sighed before giving up with a shrug.

'… Please, forgive Rin. She's still frustrated over the lives we were unable to save during the Last Grail War.'

Emiya Shirou spoke softly to the gathered individuals. They were young teenagers at best, who were from a organisation known as Judgement, an official volunteer watch program in Academy City. Where the two of them were currently infiltrating, and depending on the situation, might warrant a need for it to be destroyed for the sake of the world.

..

'Would you please explain yourself further, Emiya-san.' asked a serious Shirai Kuroko, a member of Judgment that had actually succeeded in 'bringing' the two of them in.

Shirou found her current behavior satisfying, from how they had interacted in the past, he expected her to be going on a childish rant of justice in the face of Rin's decision right about now.

Perhaps it was how it was similar to his own twisted ideal that made Shirou like the younger girl but it doesn't matter right now. What DID matter right now was to explain to these teenage girls the Holy Grail War and the danger and lethality that the Heaven's Feel Ritual would bring. It was most likely to shatter the normal lives of every individual living in the City.

But perhaps, with their help, this time there would be no causalities... Shirou could not help but remember the image of the blood stained and lifeless eyes of Ilysaviel as her life was cruelly taken away from her by the King of Heroes.

..

'Only if you're ready to throw your mundane life away.'

Shirou countered as he flashed a small smile with a hint of danger and regret at all of them. His smile was wiped off when another girl, this time one who who has been labelled as one of the most dangerous individuals in the city, slammed her palm onto a table.

'This entire week has been crazy already! Real magic users, how that idiot managed to get an entire organisation after him, secret assassins that turn out to be a real life super heroes... actual vampires and death gods... how would a secret war be any more life shattering!'

Did all of that happen in just one week? If they had gone through all those events, what Shirou was going to tell them really wouldn't be too much of a stretch.

'… Well, how do I begin...'

Shirou raised a hand to stop Rin, who was looking scandalized that he really was going to tell them about everything before going on anyway.

'I guess the first thing you should know is that during each war one would have to be chosen by the Grail War to be a Master...'

..

'Is the noodles done, Tohno!'

An albino haired individual growled, partly an echo to his own grumbling stomach as he waited impatiently at the dinner table with his fellow members of GROUP.

'Don't rush Shiki, Accelerator-yan!~ Anyway, don't you know the saying, the longer one waits, the better the dish!'

Another table mate- the delinquent like individual was Tsuchimikado Motoharu and he too was staring at his cutlery with an eager expression plasted on his face. Unlike the impatient duo, the other two individuals with them were more relaxed as they waited for their long overdue dinner.

The unofficial and yet official group that was named GROUP consisted of these 5 individuals, with their residential cook, Tohno Shiki slaving over the kitchen as he struggled to meet their expectations.

Speaking about the bespectacled boy, Shiki wasn't a very good cook, but compared to the rest of them, he was considered a god of the kitchen. That was why the title of official 'chef' was handed to him on a silver platter with sprinkles sprinkled on top.

Before he joined or when he joined the organisation, he was already aware of their eating habits. Convenient or not, having to lug two whole bags of instant noodle cups outside for disposal was not one would be fond of.

'It's almost done!"

Shiki called back even as he slowly distributed the plates of noodles for everyone to have a fair share.

'I wonder Arcuied would enjoy this...'

Shiki asked himself softly before dismissing that thought away from his mind, she would definitely like this dish. Heck, she will like anything if he was the one preparing it. Thinking about her depresses him but at the same time strengthened his resolve as well. He had to get out of this organisation as soon as he could. If only he could have more leads on the individual that he absolutely has to contact.

Deep Blood... a proven ability to attract and slay vampires without fail... whoever had that ability would be able to even threaten a True Ancestor.

'Oi, Tohno!'

Accelerator shouted at him again for the nth time tonight and it brought him out of his stupor again before he hurried over with the plates of noodles in tow.

'Tuck in everyone!'

..

'Whatever the case, now you are in danger, Kamijou-san. Once they figure out the true extent of your abilities, there is no question that they would want it for themselves.'

The purple haired girl spoke evenly in the apartment even as the other girl in the room scowled at her angrily and perhaps jealously too.

'I know that! I could have told Touma that!'

'And yet you did not, Index. It is unbecoming of you to keep the information of the Holy Grail War from Kamijou-san the moment you were aware of it.'

The Atlas Alchemist, Sion Eltnam Altasia smiled evenly at her rival in information collecting, Index Librorum Prohibitorum. Although in her case, Sion rightfully paled to the smaller sister besides her, who was able to memorize and store all the information of nearly all the grimoires in the entire world into her memory without going insane.

That was a feat that was potentially only achievable for her if she relapsed into her Vampire form, which she was confident of finding a cure if only she was allowed to tap into Index's store of grimoires.

However, that was not her mission here. She was supposed to put an end to something that Shiki should have ended for her. But along the way she discovered the unique ability of the 'Illusion Breaker', a power so radical and powerful that it would even shatter and sever god's blessing with it's bearer.

That said, Sion wasn't totally sure that was the case here... the red thread of fate seemed to be still quite strong and unbreakable for Kamijou Touma.

'Such misfortune... so who's going to be after me again?'

'Likely the entire magus association as well as Atlas would want to study your unique ability... even so, factoring you association with Academy City, together with the grudge that you held with the Church and it's many branches might make it a diplomatic incident... Perhaps it's best if you stay within the confines of Academy City for now... Despite the danger of the Grail War'

Sion looked surprised when Touma said that he has no plans of leaving so soon, not when it's getting dangerous for so many people.

'Can my power... be used to stop the Grail? Destroy it somehow?'

The boy is full of surprises and Sion paused for a moment, doing the calculations in her head before nodding her head easily.

'If your right hand can even destroy the blessing of gods, destroying the grail would be possible with a 99% success rate. Still, I would like to refine my calculations a little due to the lack of information that I have to work with...'

'So you'll help?'

Kamijou Touma sighed in relief while looking at Sion hopefully. He hadn't known Sion for a long time, but he trusted her. She wasn't one to mince words and was trustworthy, unlike a few others.

'I do not see a reason not to. The grail is a dangerous thing and it's presence would cause harm and danger to all individuals in the city... Furthermore, the two of you are targets yourself. You, with the wielder of the Imagine Breaker and Index Librorum Prohibitorum are tempting targets indeed. With either of your powers, reaching the Akashic Records is no longer just a pipe dream.'

..

'You... dare challenge a saint? Pick any fight with me and you'll be shortening your life-span.'

The Saint in front of Kamijou Touma stated coldly to the masked and clocked figure, even as his other opponent looked up at him in shock. The other boy obviously didn't think that he'll lend a hand so easily and he agreed. He himself wouldn't have, if not for his own conviction that old him that he had to do so.

'Go now, Kamijou... you still have a mission to accomplish and people to save.'

The masked individual spoke softly but full of purpose as he stopped Touma from exposing his identity to the world. Donning clothes that he inherited from the Counter-guardian counterpart, Shirou Emiya also had on a red mask and hood that preserved his identity. It was this identity that had became famous in the city and the world at large. Another addition to EMIYA's outfit were the two half-concealed sheathes that were strapped at his belt, it's concealment hiding the secret of his magecraft.

Secrecy and concealment, that was the name of the mercenary's game. He wasn't just that though. He was a hero: his reputation as a hero has spread throughout the world. A nameless guardian of the weak who appears to slay the oppressive and to uphold and champion the right of the free – that's who he was.

Still, it was a tacky and unthankful task as more often than not, Shirou found himself reliving the life of Counter-Guardian, with one notable exception to his values and oath.

'Go, Kamijou!'

Shirou spoke louder this time, and the boy paused before nodding and retreating, leaving Shirou and the saint alone. There were others who wanted to stay and fight together with him but if they did, they would just see how uneven the battle between them would be.

'Meeting me alone is suicide... but I will make an exception to you and give you the chance to leave, as I recognize you and what you stand for.'

The Saint said abruptly, shocking the pseudo Counter-Guardian.

'As a fellow champion of justice, I am appalled at how you have chosen to shield that man. He who might bring the entire world into chaos with his actions and that power of his.'

Was he right saying that Kaimjou can change the world? But it didn't matter, not now. He had made a promise to Rin and that means he can't fall here... besides, there isn't a Hill of Swords right here. So...

'He too shares our ideals... so we are all hypocrites in the end. There is no definite right or wrong, but the intent for our actions are the same'

A short silence passed between the two of them when Shirou finished. They were now simply two foes on different sides of the conflict judging each other before William Orwell sighed again.

'… A pity that I have to end another one who I share ideals with.'

Water started to gather around Orwell, spooling and spiralling into spheres before he reaffirmed Shirou's dedication to fight again.

'Are you certain, fellow knight? It is a pity but I shall end your legend today'

Shirou only had one line for him, as with all his foes, as with all of his battles so far. Only one Aria would carry him through this battle.

'She is the bone of my sword.'

Shirou closed his eyes and waited for it all to begin, after all, being engaged is the only way he knows how to fight.

..

'Y-You're INSANE! You can't defeat him! Don't you know who he is?'

It was her worse nightmare, no- it was everyone's worse nightmare. An insane Accelerator at his full strength attacking innocent civilians with no one to stop him. Who COULD stop him? The most power level 5-esper was without a doubt the strongest individual that the world had ever seen and would ever seen. Even herself, Misaka Mikoto and rank number 3 in the level 5-espers in Academy City would be defeated in 78 moves against that mad beast.

All they could do right now was to evacuate all the civilians that Accelerator might stumble upon: something that was difficult even with Judgement's help and authority, and this boy, probably just a university student said that he was going to stop him?

Accelerator's powers was the manipulation and control of vectors with him himself as the core of his abilities. Prior to his defeat by that idiot, Touma, he had terrorized as well as staked his claim as the strongest in the world with no one as his peer.

Being able to control all movement and being able to deflect anything, any force and any direction in his favor meant that he was unstoppable. No one could touch him or even graze him without having that action returned to him.

He wasn't totally invincible, though - in the face of the Imagine Breaker, the impossible power to negate all mystical, esper-related and magical powers, even Accelerator fell as well.

Still, this boy wasn't Touma (though it seemed that they were both idiotic), and that meant that he'd be killed in seconds.

..

'Oh, I know who he is... but I'm going to stop him.'

The boy sighed as he removed the glasses that he was wearing and smiled at her, despite her best intentions to pull him back.

'You're... YOU'RE CRAZY! Run away! Don't make me hurt you!'

Mikoto recovered from her shock even as she used her own powers to gather electricity around her, small sparks of power surging through her limbs proving that she wasn't kidding around. However, it didn't phase him at all as the boy simply smiled at her.

'Oh, you must be Misaka-san...' said the boy after he saw the sparks flying off her person.

'It is a pleasure to finally meet you, Miss Railgun... I heard plenty about you... I'm just happy to see that you're as energetic as what they make you out to be.'

Mikoto was nonplussed by his words, and she stared at him for a while before asking him who he was.

'Ah... If you really need a name...'

The boy shrugged before his eyes narrowed, focusing on the person in front of them. Mikoto herself whirled around to see Accelerator grinning at them. No, that was not Accelerator. If Tohsaka-san and Emiya-san was right, this was just an illusion, a being created from her own fears... or the Academy City's fears of Accelerator going berserk.

But it doesn't mean it was anything less real, or intimidating or just plain terrifying.

The look of blood lust, eagerness to kill and utter contempt and dismissal for her made her knees weaken. Especially since she knew that retreat was only her option and taking him on was suicide.

'Call me Nanaya.'

The boy answered suddenly as he drawing out and brandishing a small pocket knife beside her.

'W-What are you-!'

Mikoto did not even finish her sentence before 'Nanaya" had dashed towards Accelerator quickly, his footsteps a blur and totally silent as he engaged Accelerator by himself.

'Stop!'

Mikoto did not want to see anyone die like this in front of her but instead of seeing the boy get killed in a bloody mess, the exact opposite happened: Accelerator's arm slid off easily thanks to the clean cut made by the simple switch blade. Blood was flying everywhere even as an expression of shock appeared on Accelerator's face. It was so fast and so surreal that Mikoto couldn't believe what happened. A simple stroke of Nanaya's knife was enough to sever the limb of the strongest esper in Academy City?

'W-What... are y-you?'

The illusion that was Accelerator gasped or just stared in shock before his face paled even more at the expression that the man was showing to him as he grasped his arm – now a short stump – out of panic and pain.

'A death god.'

Mikoto swore she heard him say before the knife was plunged into Accelerator's chest with no mercy at all.

..

Sion Eltnam Altasia simply stared at her savior in shock. Yes, savior was the only word to describe the man who had just lifted the spellwork off her. It was supposedly impossible, - something that even the True Ancestor herself said couldn't be done - but with a single touch of his, the hunger that she felt rumbling in her stomach was gone. It was all gone, together with the superhuman strength and stamina but Sion did not care. She was freed, freed from the curse of Wallachia in front of the Dead Apostle's eyes and that shock caused the both of them to just stare at the human boy in front of her.

Was he truly human at all? Sion was reminded of the time she met another Wild Card like him, the living Death God, Tohno Shiki and her shock then and now was almost comparable.

Almost.

'I-Impossible! To lift the curse of a vampire?! What are you!'

The Dead Apostle stared at the panting human boy in front of him even as he scratched his head and said that he really didn't know too.

'So it's true... you're the one who started it all.'

The boy, Kamijou Touma cracked his knuckles before dispelling yet another bout of supernatural power from the Dead Apostle with ease.

'Now then, Vampire... to save everyone else, I'll shatter your illusion myself!'

The boy started running running towards him, just a mundane human... no, not a mundane human, someone who quite possibly could change all fate like the Wild Card before him.

Touma and his Illusion Breaker and his courage: that was something that Sion believed in as she staggered to her own two feet.
