A/N: Just finished my test questionnaires and I thank all of those people who reviewed my fanfic –bows down in gratitude –. Many thoughts and ideas have been swirling in my mind right now (thanks to playing Yu-Gi-Oh and the suggestions of the reviewers. – evil laugh mode –). By the way I put easter eggs (sort of) in there. For Type – Moon fans, you know where to look. :3

Chapter 5: Let the Grail War Begin

On that day, a war will begin.

A battle of superiority

And a battle of wishes

Of Masters and Servants alike.

Only one pair will remain

To make a wish to the Grail.

These are the events of the Fourth Heaven's Feel War.

The way you've been dressed up, together with your ears and tails, you might as well place neon signs above your head. Kejoro flatly stated mentally while waiting for the train going to Fuyuki City. Caster, thankfully, was in spirit form while she's talking to her.

Look who's talking. Caster snapped back. You're dressed in an elegant "baring – your – assets" kimono. You even coupled it with leather gloves that look like you're going to have a fist – fight.

That's for a good reason. I'm not like some Master who will reveal the identity of themselves as a Master. She stated it like it is common sense.

If you say so. Caster can't form a counter argument for that. But, the kimono still counts.

That's because I can't breathe properly if my kimono's too tight! Veins are popping in her forehead by just trying to reason out why she had clothes like that. And somehow, she must get back at her. What's the reason for not hiding your tail and ears?

Caster did not speak for several seconds. Kejoro knows of her Shapeshift ability being A ranked, but somehow she had hit a nerve on Caster for mentioning it during one of their arguments.

At the same time the train arrived. They waited for several seconds for the train to empty some cars before they come in themselves. As the train started to speed up little by little, the mood between Caster and Kejoro became more and more depressing.

Personal reasons… Thankfully Caster spoke, but with a melancholic voice that ruined the energy of a bubbly lady. Kejoro tried to dissipate the depressing atmosphere by reassuring her.

Things are different now, so whether you like it or not, you have to use it. Otherwise, we'll lose our purpose.

I guess you're right. Sooner or later, I might use my powers. She sadly replied.

Think of it as atonement. Though I think that the ones who are wrong in the first place are the onmyouji. She jokingly stated it mentally, to which Caster laughed and forget their earlier arguments. At first, she hesitated, remembering the traumatic events that took place when she used her powers, especially the one which led to her death. But what Kejoro had said makes sense. If she wants to stop the bloody game that is the Grail War, she must go all out herself. Then, she slowly shifted her shape to remove the tail and ears.

Now you look even more beautiful. Kejoro praised Caster, which Caster brushed it off with an affirming smile and a confident stature.

Of course. She proclaimed with a dramatic flipping of her hair.

With the passing of the bullet train through the boundary of Fuyuki, Caster unknowingly left a shattering brief spike of prana which disrupted the magical boundary for the moment, causing a short alert status for the knowledgeable Masters and the Servants alike, as well as the magi and the priest supervising the event for the Fourth Heaven's Feel. What is seen as inconceivable inevitably happened in front of their eyes.

"Pardon me for interrupting your conversation, but it seems that we have another master and servant." A woman in a skull mask and black clothes notified both priests that were in the church talking about the strategy that they will deploy after Tokiomi sent them a message to let the Assassins serve as onlookers for the duration of the war.

"That's impossible." An elderly priest flatly emphasized. "The Grail only chooses seven masters and seven servants. It's impossible to have an eighth…" he cut his sentence short when he felt a spike of ominous feeling that quickly disappeared.

"Father…"

Turning to his son, he said "Kirei, find out who that pairing was through your Assassins. But make sure they're not seen by other servants, and if they're weak, eliminate them quickly."

"Yes, father." The man called Kirei replied, and gave the command to the Assassin who was playing with 2 Dirks in his hand.

"Sure thing, master. I'll make sure to kill them as quickly as possible." He stopped playing with his Dirks, placed them in the makeshift sheaths in his legs then he disappeared in a black smoke of aura.

"Oho, looks like I'll enjoy this world a little longer than the time that I have set for myself." A blonde man with red slitted eyes smirked as he also felt that brief spike of ominous feeling that entered the boundaries of Fuyuki City. He is dressed in his "casual" clothes, which really are expensive clothing materials of the highest quality.

"Even so, we must be careful, King of Heroes. We don't know who they are, or what their purpose for the Grail war is. Besides, it's not normal for the Grail War to have eight servants." A man in a red suit tried to reason out to his servant.

"You dare lecture me, Tokiomi?" the man called the King of Heroes inquired with great disdain. Tokiomi just gritted his teeth in anger but he did not show it to his servant for fear of losing his trump card in the battle.

"No, my king." He reluctantly replied.

"Good."

Tokiomi resisted the urge to curl up his hands into fists.

"Well then, I shall make preparations for myself. Do not dare to interrupt my battle, or else you'll suffer the consequences. Remember that, Tokiomi." He stated before disappearing in a golden mist of light.

That arrogant bastard of a servant. One day I'll get even with him. He thought as he tried to compose himself after Gilgamesh has disappeared. He hated the fact that he summoned an Archer with a really high Independent Action rank. He expected that event to summon a Saber, but by him being summoned as an Archer gives him an even higher blood pressure just by maintaining his composure in front of the arrogant king.

This is for the reaching of the Root. He reassured himself by that statement.

Aside from the unorthodox methods of using the craft, the number one enemy of Magi is technology. They believe that it only hinders the way to reaching the Root. And the one who only takes advantage of their pride in the so – called craft is the Magus Killer, Emiya Kiritsugu. Many magi have been caught off – guard by his underhanded tactics.

"Kiritsugu…" she tried to inform him but Kiritsugu cut her off. He was assembling a Walther rifle, while Maiya was putting finishing touches to the Calico sub – machine gun when they both felt that brief spike of prana.

"Yes, Maiya, I felt that. An eighth servant. This should be impossible, yet…" He is in deep thought for several seconds after he paused in the middle.

"What shall we do?"

"Just another pairing to eliminate, of course." He concluded with a cold façade, while locking and loading his Walther rifle several times to ensure accuracy and fluidity, which Maiya have taken it that Kiritsugu has recovered after he lamented over the fact that his daughter Illya, although she's eight years old, weighed less than his Walther.

I wonder what Iri was doing right now… He slightly wondered while testing the sharpness of his combat knives. His Thompson contender was in good condition, although the loading time of it is longer than the last time that he had used it. He prepared the Springfield bullets, along with the Origin bullets, and placed those in convenient cases, being careful not to mix the bullets up. Also, high – grade C – 4 explosives, grenades, smoke bombs and flashbangs are in order, some of which being bought from a certain Yakuza boss who was his acquaintance during certain missions.

"Another servant?" What Irisviel thought was impossible, it happened. She felt that ominous aura that dissipated immediately after entering the boundary of Fuyuki. "But it's supposed to only have seven."

"You mean there was a wildcard pairing out loose?" Saber said while walking down the streets of Fuyuki city together with Irisviel.

"I think so. The Grail was supposed to summon only seven servants. But if my information on the Third Grail War is correct, someone summoned two aspects of the same Class, which is Saber."

"Then following that information's logic, it can be possible, am I right?" Saber concluded, more like a statement than a question.

"If you put it like that, then it can be a yes." Iri frowned, but Saber put a reassuring hand at her shoulder and they enjoyed the overlooking scenery of the buildings while they have the time to do so, since it will be only hours before the Grail War will start.

"But as the holder of the Grail, I'll make sure that the one who will get it is my husband, Kiritsugu." She smiled and held Saber's hand. "Let's do this together, Saber."

Saber replied with a nod and looked up at the crimson afternoon sky as the sun begins to set down. It reminded her too much of Camlann's fields, but as long as she gets the Grail, she'll remember those fields no more.

"By the way, before we go to war, I want to show something to you."

"What is it?"

"It's a surprise."

The train stopped by the terminal of Fuyuki City, where many people hustled and bustled as they try to go home in a rush. Kejoro and Caster felt no different, as they try to rush too, only difference is that they are rushing to a perfect location to set – up a base for the war.

Are trains really that jam - packed? Caster tried to inhale the oxygen that she lost during that rush. Kejoro looked at the time on her watch.

I suppose so, considering the time. Kejoro stated as she rummaged for some things and double – checking that she did not lose anything, including a map and a wallet.

You looked like you are only here for the tour. Caster snided, to which Kejoro did not mind.

Better be prepared than nothing at all. She replied with a smirk.

They tread along the path to the so – called base of operations, when they sensed someone was following them. Kejoro felt uncomfortable with the situation so she called mentally to Caster.

Caster…

Yes, I felt that too, Kejoro – san. Let's engage him somewhere else.

They went to a dark alley to avoid any possible witnesses. Caster quickly formed a 3 meter radius boundary field around them, including the assassin in the boundary, as an additional countermeasure to the familiars, cutting off effectively any outside communication, and for the assassin to be trapped. A Dirk flying towards Kejoro is caught by Caster in spirit form. She manifested in casual clothing, with ears and a tail, after catching the Dirk.

"Goshujin – sama, do you have any plans?" She asked as more Dirks appeared but were blocked by her barrier. She didn't realize that Kejoro is gone until she turned her head to where Kejoro was in formerly. Fortunately the barrage of the weapons stopped, but as she let down the barrier she gritted her teeth, before she decided to calm down.

Really, Goshujin – sama. Caster just sighed and decided to catch up with her reckless master.

Meanwhile, Kejoro sped up towards the white – masked man, using the training that she had for one week, which is reinforcement. Maybe it was her, or it's just the adrenaline, but she did not feel exhausted while using it unlike the first four days of crash course where she was spent after just a few seconds of reinforcing. And she's not punching anything yet, not like now.

She reinforced all parts of her body to keep up at least with the bullet speed that the assassin possessed. She blocked every Dirk flung at her by her closed fan, as the man increased his speed to swiftly kill the prey. He aimed at the vital part, to which Kejoro almost evaded with precise timing thanks to her reinforced eyes. Then, finding the back of the assassin, she took a stance and delivered a quick but powerful palm strike using her reinforced hands. Using the Dirk that stuck in her fan, and her hair as a binding device, she somersaulted in mid – air, caught the assassin and landing down with grace, placed the blade of the Dirk on his throat.

"Are you suicidal?" Caster caught up and exasperated when she found out about what Kejoro did to the man. "That white – skull masked man is a Servant! You're fortunate that he's one of the weakest Servants in this war. Besides, the usage of your prana is not perfect yet!"

"I think it's better to test it out in real battle. I want to test myself on what are the limits of my usage of prana as a secondary source of power. Based on my performance, this means that this one's really draining when you distribute it evenly and use it at maximum power at the same time." She explained while exhausted from the battle.

"It can't be helped. One week's really not enough for this, so you do have a point." Caster admitted.

The assassin cannot believe the predicament that he was in. For him, this is rich beyond words. A human capable of defeating a Servant? And with the current speed that he had? That is impossible, unless…

"You're a spirit, like me." He concluded jokingly. A joke can dissipate anger but not hostility.

"What of it?" she quipped while still panting, taking slow deep breaths to remove the excess rushing that she feels right now.

"Only spirits like you can defeat a servant like me. But it's not enough to defeat the Knights, especially with a servant as weak as a Caster – class Servant." He boasted with confidence. But at that point, he wished that he should not have said that.

Letting off a venomous aura, Caster said with hazed golden eyes and a familiar creepy smile while cracking her knuckles in preparation for her special technique. "Suddenly I have the feeling of happiness to twist his arms and legs off and rendering it asunder in flames before pulling off a Castration Fist. Or maybe dissecting his body with his weapons, and then finishing everything off with his weapon overloaded with prana. Goshujin – sama, will you please give me permission to do so?"

Crap, she's more murderous than the other Caster that we heard about. Assassin mentally gulped as he prepared for his death. But at least he disseminated the information to the other assassins before he'll die.

"No." Kejoro flatly replied, to Caster's disappointment. But thinking about it, she might gather some information on the enemy, mainly on Saber. Assassin just smirked on his fortune, preparing a poisoned knife to fling at Kejoro. That smirk did not escape Kejoro's notice.

"But on another note, I think he notified the others, so just give him a quick death." She gave the Dirk to Caster, to which Caster received it with a murderous glee and overloaded it quickly with prana, being careful not to let it explode until it made contact to the body. With the broken Dirk in her hand, Kejoro letting go of the prisoner, and before Assassin could fling the knife, she gave a mighty stab to Assassin while letting the weapon explode to smithereens, blowing off Assassin, and leaving no trace of blood from the additional spell that Caster used.

"That's the second one." Caster quipped after letting the barrier dissipate. She felt alive for the moment after killing Assassin, since he was the first one to underestimate a Caster in battle.

"How many assassins are there?" Kejoro asked while picking up some Dirks to use.

"Based on my estimates, they would be around 100, if I include the one that Archer killed and the one that I killed." Caster replied while magically changing her outfit to a gothic dress and hiding the ears and tail again through Shapeshifting.

"Well, that's life." Kejoro sighed. "The odds are not in our favour, so we must do something to even those odds." She paused for a moment before saying this. "Caster?"

"Yes?"

"Who were the so – called 'Knights' that the one was talking about?"

"Oh, those knights. Those are the classes of Lancer, Archer, and Saber. Those go by the names 'Knight of the Spear', 'Knight of the Bow' and 'Knight of the Sword' respectively." She explained. "Top Class is Saber, second one is Archer, and the last is Lancer."

"Well, Saber is to be expected at the top notch. Let's go to our base, before it will get late."

"It already IS late, Goshujin – sama." Caster replied as they felt a surge of mana coming from the direction of the shipyard.

"And I am hungry too. We should stop by at a fast – food shop first." Kejoro said, feeling the hunger long suppressed in her earlier battle.

"OKAY, but please make it quick!" Caster chided, quickly dissipating into spirit form. Kejoro then rushed to the first shop that she sees, which is a bar and coffee shop named Copenhagen. She bought and ate there before continuing their journey towards the shipyard through a taxi.

A boy was watching the event through the tiny bird that he sensed mid – air.

"Is she really a Servant?"

"I guess so, boy, and I have a feeling that she's the one who let off the ominous aura earlier while passing through the boundary. This could be more fun for me!"

He sighed at the meaning of "fun" for his Servant.

Upon arriving there, she used her Osore to conceal her presence, and Caster deployed a small range boundary field in a secluded area for observing the battle. She gained control over most birds flying aimlessly for a better view of the servants who will participate in the battle. So far, all she sees is a man in dark cyan tights and with two spears in his hands.

Basing on his appearance, he's a Lancer. Kejoro - san, please be careful of him. He's got a charm.

"I can see that" Kejoro tried to shake off the love – at – first – sight feeling that she has for the man right now. Caster decided to let Kejoro wear one of her talismans.

Here. She produced a charm from her cleavage and gave it to Kejoro. It will prevent you from being attracted to the man.

"Thanks. That's a great help." Kejoro thanked Caster before wearing it.

No problem. Caster smiled. Then her ears moved, as if she heard someone. Here they come.

They saw the blonde lady in a suit, accompanied by a lady in white clothes. After a conversation, the lady then changed her suit into armor, and held something akin to a sword.

That wind covers up everything nicely. Good thing, if you want to keep your identity hidden. The Saber class sure is amazing. Caster marveled at the servant in a blue dress.

"But she looks like a fifteen – year old girl. How come she never grew up?" Kejoro wondered loud enough for only Caster to hear.

Who knows? But remember, Saber classes are always the strongest Servants. So even if she's a child, we shall take extra care of ourselves. She warned Kejoro. The battle will start right now, so please stay focused, Goshujin – sama.

As soon as she said it, so begins the clash of weapons. The battle for the Fourth Heaven's Feel starts on this day, where seven pairs of Masters and Servants will be tested of their worthiness for the omnipotent wish – granting device called the Grail.

A/N: I thank everyone for reading my stories, and I apologize for the delays that I caused.

Terms and weapons:

Dirks(maybe mispronounced by some as Darks) – the Assassins' projectile weapons, used for swift kills. If you have read Fate/Stay Night, then you know that the assassins have some of these weapons one way or another. Look up for the Type – Moon wiki for information (and by the way, I'm one of the editors there. XD)

Walther Rifle – a heavy rifle Emiya Kiritsugu uses for recon. This enables him to see Magi through his modified thermal sensors. For more details, refer to the Type – Moon wiki.

Thompson Contender – Can serve as a Mystic Code if paired with Origin Bullets. For more details, go to the wiki that I mentioned above. I also based it from the novel.

Springfield Rifle bullets – serve as replacement bullets for the Thompson Contender.

Independent Action – a skill prominent in Archer classes that enables them to move away from their Master. A high rank in this skill enables them to live even for days without a Master, as long as they have prana reserves.

Broken Phantasm – a weapon overloaded with enough prana to explode on contact. It also converts the weapon from a lower rank to a higher rank. This is one of F/SN Archer's specialties, as his swords Kanshou and Bakuya becomes Overedged versions from the overload of prana.

Osore – Fear. Skill among youkai.
