Chapter 5: Attack on Einzbern

"It is done."

Risei Kotomine was quite pleased with all that transpired. Upon learning that Caster the ones were the one behind the kidnappings and murders that had been happening as of late, he and the Master of Tohsaka devised a plan that would not only eliminates Caster and ensures that Thaumaturgy remains a secret, but also provides the Master of Archer with unique advantage over his rivals.

The first part of said plan was to use his emergency powers as judge of the War and decreed that whosoever slays Caster and his Master would be handsomely rewarded with an extra Command Seal. Though none of the Masters have used theirs yet, having an extra would no doubt tip the scales of balance to their favor.

"Well done, Father Kotomine." Tohsaka Tokiomi praised the priest with a smile as they conversed via magic phonograph "Now all the other Masters will hunt him down like the dog he is."

"Indeed." Risei nodded sagely, standing upright while speaking with his son's mentor "And though alliances may be formed, they will let their greed get the better of them and fight over who gets the honor."

"Aye, but should Caster fall to another, the winning Master would have an advantage."

"Yes, we cannot allow that." The elder Kotomine grinned malevolently under the candlelight "For once Caster has exhausted himself from defending against the other Servants, Archer will be there to finish him."

"Are you sure that's how it'll go, though?"

The old priest nearly had a heart attack, jumping upon hearing that familiar, exaggeratedly saccharine voice that belonged to Assassin, his son's Servant. There she stood, her hands folded in front of her while she wore that jubilant grin on her face.

"Will you stop doing that?!"

"Everything alright there, Father Kotomine?"

"It is nothing. Just another one of Assassin's antics." Risei waved off the concerned tone of the younger man "And what are you doing here? Did my son not tell you to keep watch?"

"Aww, but I am!" She giggled while sticking her tongue out "My clones are watching the other Masters while I'm keeping my guard, but I cannot help but overhear what you guys are talking about..."

"Yes, and what of it, Servant of the Shadows?"

"Weeelll..." The pink-clad Servant made the exaggerated motion of putting a finger on her chin, her expression one of deep thought "I just wanna point out that some of the Masters would see this as an opportunity to pick off the hunters while they chase the poor bunny."

"Are you implying that other Masters may disregard this temporary ceasefire? Preposterous!" Rise scoffed at her notion "The lure of an extra Command Spell is a prize too difficult to ignore!"

"It's what I would do." Assassin shrugged in response "Also, didn't Kirei-kun's intelligence say that there's a certain Magus Killer out there that doesn't follow the traditions of a Magus?"

"She is right." To Tokiomi's surprise, Archer had decided to join this conversation, materializing right beside his Master as he spoke "Saber's Master is indeed a cunning one. If what your student says is true, Master, then Emiya Kiritsugu will take the pragmatic approach and strike just as we chase after Caster, leaving our backs vulnerable to his schemes."

Tokiomi had given the words of both Servants some serious thought, placing his hand on his bearded chin to mull over it. After some contemplation, he nodded to agree with their assessment.

"Very well." He nodded before turning to his Servant "If you have a plan, Archer, then I would love to hear it."

"I have already thought of one." The Son of Sparda answered with a small smirk that matched his Master's "And for it to work, I have need of Assassin and her Master."

"Oh, goodie~!"

"Are my documents in order?"

"Filed and sorted as requested, sir."

"Did you call the OSG?"

"The future Mrs. Evans was the one who answered, surprisingly. A meeting has been set for later today and I'll be making my own way to their headquarters during your flight."

"And my brunch with President Clinton?"

"Already moved to Saturday, next week."

"Well done. As efficient as ever, Miss Valentine." Salem Azal's chuckle was heard from the other end as Scarlette Valentine, a witch-turned secretary to the CEO of the world's leading IT company "I shall be expecting a full report of your meeting with Mr. Silverstein when we meet in Fuyuki. Until then, farewell."

"Farewell, sir." She spoke as she hung up. With that piece of business settled, she turned to the two others present in the basement of Progressio Enterprises. One was a girl clad in what could only be described as a red leotard that showed much of her midriff. Her pink hair was tied into pigtails that flowed freely down her shoulders, and her features could be best described as doll-like; almost expressionless, even. However, her eyes, which perfectly matched her hair, showed a certain softness.

The other was a boy around the girl's age clad in a black blazer over a white polo and black slacks and sneakers and wore a red scarf around his neck. He also showed a certain gentleness in his eyes, something he hid with a usual stoic expression.

"Mr. Ouma, Ms. Yuzuriha, it's time."

"Yes." Both individuals, two souls whose destinies were intertwined, followed Scarlette as she made her way towards the center of the room, where the circle was drawn and the preparations were in place.

"A simple portal spell to the Order's Headquarters?" the blonde smirked as she began the spell "None too difficult for the Witch of Elrit Forest."

"Here's what we know about the opposing Servants so far."

Once Saber had brought Irisviel back from the Ahnenerbe, it was back to business as usual. Maiya had placed a projector on the table, the object illuminating the otherwise dim room. Kiritsugu was up front, pointing to the images projected on the wall while the rest were listening intently.

"First up is Lancer." The images of the female Servant's clash with Saber flickered on the screen "From what intel we already have, her Noble Phantasm is the one we have to be most wary of."

Irisviel nodded in agreement. Having front row seats to the spectacular duel certainly helped form her opinion "In addition to it's inherent dragon-slaying qualities, her spear seems to allow her access to some degree of Magecraft, something not uncommon for many heroes."

"And her Master is quite the formidable magus." Kiritsugu continued as said Master's visage graced the wall "Lord Kayneth Ell-Melloi Archibald. A lecturer in the Watch Tower, an expert in Spiritual Evocation as well as a renowned Magus. He is currently staying at the Fuyuki Hyatt Hotel with Lancer and his wife-to-be, Sola-Ui Nuada-Re Sophia-Ri. Attacking their stronghold now would be suicide due to the defenses he had set up."

"Maybe there might be a way to draw them out into open battle?"

"I have one or two ideas." The Magus Killer stated casually to answer Saber's question. Said ideas involve blowing up the entire hotel to bypass the magical defenses set up, but he didn't mention that aloud "Moving on, next is Rider."

Seconds later, images of the Servant and his Master appeared on-screen "Judging from his attire as well as his craft, we can safely assume that he is not a hero from the past, but from the distant future, one where technology has advanced beyond our wildest dreams."

"Is that even possible?"

"The Throne of Heroes can call forth heroes from the past as well as the future." Irisviel answered "I wouldn't be surprised if that were the case in the previous Grail Wars."

"In any case, his Master, Waver Velvet, is the easiest one to eliminate. But as stated earlier, he is from the future. As such, we don't know what he's capable of. Then there's Assassin."

The next photo was that of the pink-clad lolita, grinning while holding that purple scissor of hers "We don't know how she faked her death, but judging from the video feed from her 'battle' with Archer, it is possible she used a double to engage him back then."

"As one who has encountered her personally," Saber chose to join the discussion "I can say this: do not be fooled by her appearance. Assassin's killing intent is unlike anything I've ever seen."

All looked at the Servant of the Sword, especially her Master who was considering her words since Assassin was his rival Kotomine Kirei's Servant.

"The same can be said for Caster." The next image was that of the nightmarish Servant, his wings extended to give him the look of a creature straight from hell "If anything, he's one of the most formidable in this War. From what we have seen, he has been able to utilize magic that could almost be described as demonic."

"My Magic Resistance should make short work of any sorcery that fiend may have." Saber replied confidently.

"That definitely is true." Her Master nodded "But the fact that he can keep up with Archer's swordplay, which in itself is an oddity, means he should not be underestimated."

"Speaking of Archer," Maiya chose to speak next as the images changed to the blue clad Servant "It should be noted that Tohsaka Tokiomi is his Master. From what we can confirm, those ethereal blades he tosses are his Noble Phantasm, as well as that katana he carries around."

"Sadly, there are no records of such a man in the history books." Irisviel sighed deeply "The same can be said of Berserker."

"Yes, the fact that he is sane despite his Class assignment is intriguing." Kiritsugu nodded as the last blurry image of the red-clad Servant of Madness showed up

"The moment he made his attack, he shouted out 'Belial Edge'. Perhaps it's his Noble Phantasm?"

"If it is, it's a start. We can use it as a clue to discern his identity." The Magus Killer answered in response to Maiya's query, then turned his attention to everyone else in the room "As you know, the Judge has decreed that Caster is to be eliminated and that the reward would be an extra Command Seal. Our plan is as follows: We are to chase after those after Caster, since they will make for easier targets."

"Master..." As she listened, Saber began clenching her fists, her expression that of indignation "Just how despicable can you get?"

"Saber!"

"Just how much to do you intend to mock us Heroic Spirits?! Why won't you let me fight?!" The blonde King of Knights ignored Irisviel and was about to proceed into a full rant about Kiritsugu not trusting her when...

"Nggh!"

All turned to Irisviel, who felt as if a shock coursed through her system "Someone..." she said as she tried to steady her breathing "Someone has broken through the protective field."

Moments later, both Kiritsugu and Maiya armed themselves to the teeth as Iri prepared a crystal ball. With it, she scanned the forests surrounding Einzbern Castle for the intruder until...

"Found him."

Both assassins and Servant gathered behind Iri to see what she had found. Sure enough, a vivid image came into view; it was a figure whose pale skin and silver hair shone in the moonlight, his blue coat billowing in the wind as he casually took a stroll in the forest.

"It's Archer..." Iri was the first to speak.

"It seems that Tohsaka Tokiomi was more daring than we believed, for him to be sending his Servant like that." Maiya watched intently as the Servant of the Bow slowly made his way towards the castle.

"At any rate, we should be wary when dealing with him." Kiritsugu spoke next, his fogged eyes keep an eye on the crystal ball "For all we know, Assassin could be waiting on the wings."

Irisviel nodded before turning to the blonde Servant with determination set onto her features "Saber...I command you to defeat Archer!"

"I shall, milady!"

"They've taken the bait."

Archer smirked as his slow walk came to a stop. From a distance, he could easily discern Saber, clad in her wartime vestments, running towards him with invisible sword drawn.

"So you've responded to my challenge." he spoke calmly as she stopped in her tracks

"I have." Saber nodded as she assumed a battle stance "And why have you come, Servant of the Bow? I did not assume you to be one so brazen to charge into the enemy's stronghold by yourself."

"Perhaps." Archer's shoulders shook slightly as he let out a chuckle "But what if I decided to come here based on an assumption?"

"Oh? And what assumption would that be?"

"That Servant Saber is the best swordsman among the Seven." He smirked as the hem of his coat was pushed back with a gesture of his hand "For you to have been placed at your Class would mean that you must have been the greatest swordsman in your time. Well..."

Before Saber could even blink, Archer had vanished into thin air. She kept her form, looking around warily for any sign of the enemy.

"I would like to prove you wrong."

Her instincts turned up to eleven, Saber overcame her surprise and whipped around to see Archer drawing his katana faster than the eye can perceive. She was barely able to raise Excalibur to avoid getting cut, but the strength behind the blow rattled the King of Knights, forcing her to skid back several steps before coming to a complete stop.

"For your blade to have withstood getting cut by Yamato..." The blue clad Servant nodded in approval "It must be a truly impressive Noble Phantasm."

"You would think so, Archer." Saber stood at ready once more, her expression telling him that she would go down kicking and screaming before she yielded "But that trick will not work a second time!"

The Servant of the Sword wasted no time charging at her foe, swinging her blade in a swift barrage that would prove daunting to defend against. Archer met her blow for blow, Yamato clashing with the invisible blade as sparks cascaded the otherwise dark forest.

Both warriors exhibited different styles of swordplay; Saber, the way of the knight that consisted of bashing and hammering, whilst Archer fought with the tenets of Bushido, which could be described as delicate yet precise. It was on this night that these two sword styles, as different from each other as the East is from the West, clashed in one glorious display.

"Not bad, Saber. Your swordplay is truly impressive." Archer smirked as he deflected a thrust to his side before jumping back "But did you forget why I was assigned as 'Archer'?"

Saber looked up to see several blue swords hovering behind her foe, each of it's edges pointed dangerously at her before Archer sent them at her with a single gesture.

"Damn it!" She grimaced as she opted to face her foe as a king should; charge at him while bobbing and weaving between the swords, swinging her weapon to deflect any she could not avoid. While such a blitzkrieg was proving beneficial, she inevitably didn't escape unscathed; several of Archer's projectiles caused several gashes on her arms and legs.

"Servant Saber is quite spirited, I will give her that." Archer smirked as he quickly drew Yamato to meet Saber's empowered slash "But how long will it take before she realizes that I am just the decoy?"

"It seems that Saber and Archer are equally skilled-ngh!"

Kiritsugu and Maiya gave Irisviel looks of concern, but quickly brushed them off "I am fine...it's just that another Servant as well as a Master had arrived."

"Can you search for them?"

"I can." Wasting little time, Irisviel gazed into her crystal ball, scrying for any signs of an enemy until she locked her gaze unto the castle's front door "There!"

The Magus Killer and his attendant gazed as she did, only to find nothing. There were about to give up when the sight of said door getting sliced into several pieces got their attention.

"Who could..." Maiya immediately hushed herself into silence as she immediately got her answer: a certain pink-clad fashion designer of a Servant skipping out of what used to be the door rather casually with an umbrella in one hand and measuring tape in the other.

"Assassin..."

"Wow~! This place is sooo chic~!" Assassin giggled as she stepped into the foyer "Ragyo-sama would've loved it here-!"

She was cut off the moment the sound of tripping wire was heard, which was followed seconds later by a massive explosion that engulfed the Servant. As soon as the smoke clear, Assassin found herself unharmed. Though being covered with soot did little to improve her mood.

"...Owwie."

"Calm yourself, Assassin." The deep baritone of her Master caused her to immediately turn to acknowledge the arrival of Kotomine Kirei "So far, everything is going according to plan."

"Yeah it is." The Servant found herself agreeing "Though I honestly wanted to fight Saber-chan! I'm sure she'd make a marvelous model for a possible summer collection!"

"Please keep your ramblings to yourself." Kirei found himself shaking his head in dismay.

"Aww~! Don't be so stiff Kirei-kun! Remember what we talked about." The pink Servant giggled as she walked ahead of him "Just have fun! La vie est drole~!"

"La vie est drole...what does that even mean?" The younger Kotomine asked himself as he followed his Servant. Much of what she had said earlier began awakening certain doubts in his mind. Right now, however, was not time to mull over this. "Keep vigil, Assassin. And watch out for-!"

Another loud explosion caught Assassin unawares, causing Kirei to just sigh.

"...Traps."

"This is bad. They have breached the castle, sir."

"I know." Kiritsugu nodded as he loaded his Calico with ammo "Maiya, you are to escort Irisviel while you have the chance, and away from Saber and Archer if you can."

"Kiritsugu?"

"Without Saber, this place is no longer safe to be in." Kiritsugu dutifully explained "Make use of the secret passageways while I hold Assassin and her Master off-"

No sooner had he spoken that the door to their meeting room had been sliced to ribbons.

"Found you~!" Assassin giggled as she stepped out of the rubble with manic glee on her face, a resounding click coming from her setting her measuring tape back in place. She took a good look at Kiristugu, her eye examining him inch by inch before sighing, as if she was disappointed with something "You know...your outfit is sooooo 1940s. Perhaps you can come with me and we'll make some alterations? I was thinking red. Lots of red~!"

"Iri, Maiya, run!" No sooner had she finished her sentence that Kiritsugu trained his Calico at her and opened fire.

"Aww, you think you can fight me? How cute~!" Assassin extended her measuring tape and swung it around like a whip, slicing each and every bullet in half. She was about to strike when she found that all three of her marks had disappeared. She looked around to see signs of a secret tunnel having been opened during the entire time she was speaking to Emiya Kiritsugu.

"Wow, he's a lot smarter than I thought." Assassin giggled as she began to give chase "No wonder Kirei-kun's obsessed with him!"

"This way, hurry!"

Maiya had taken the lead while Kiritsugu brought up the rear, both of them encircling Iri to protect her. Ever since they had escaped Assassin, who was no doubt giving chase, they had been running endlessly through the endless corridors within Einzbern Castle, no sign of any opposition in sight.

Imagine their surprise when Kotomine Kirei emerged from one of the corners like a ghost.

"Madam, look out!" Maiya pushed Irisviel aside and opened fire on the priest. His bulletproof priest robes took the damage, which he took in stride as he brought out his Black Keys. She brought out her dagger and swung at Kirei, who ducked to avoid get killed.

Kiritsugu was about to fire his Calico at Kirei when he saw Assassin from the corner of his eye giggling as she walked towards the three. In response, he quickly pulled out a grenade from his coat and threw it. At this, she just giggled.

"Heehee! Let the carnival begin~!"

Saber quickly whipped at the direction of the castle the moment she heard the explosions.

"Ah...looks like all is going according to plan."

"What do you mean?!" The knight growled at her opponent, her graceful features contorting into a mask of righteous anger, one he noted with a smirk.

"If it were up to my Master, he would have waited until Caster was weakened from fighting the other Masters." Archer explained smugly "But as pointed out by that annoying wench, Emiya Kiritsugu would attack while we were busy with Caster. As such, I proposed this plan; I act as the distraction while Assassin and her Master will zone in on your Master."

"That means..." Saber thought for a moment before a look of horror dawned upon her "Lady Irisviel!" She was about to run back to the castle when several swords dropped right in front of her, acting as a cage to keep her in place.

"Where are you going, Saber?" Archer chuckled as he walked towards her with malevolent intent "We have only just begun!"

"Damn it..." The King of Knights cursed as she placed both hands on her sword. With the developments that have arised, she saw that she no longer had no choice. If she was to break through, she'll have to bring forth Excalibur.

"So be it." She growled as she was about unleash her greatest Noble Phantasm when...

"Phozon Burst!"

A big flash of light forced Archer to jump back lest he be struck. Both he and Saber were quite surprised when a third Servant had joined the fray. The new figure was recognizable to Saber especially; after all, they had both fought the night before.

"As much as I do not wish to interrupt such a clash," Lancer's soft voice echoed as she floated down into the center of the fray "But I wish to let you know that the honor to slay Saber belongs to me!"

OSG Headquarters

"It...It can't be."

The usually cool Edgar Silverstein sat in his desk viewing a crystal ball that showed what was happening at Einzbern forest at that particular moment. Scarlette Valentine, who provided said crystal ball, was sitting opposite of him. She too was watching intently and shared his shock, but was dwarfed by Edgar's own. Indeed, the look on his face said it all.

"Gwendolyn..."
