Fate/Stay Night:

Undead Blade World

Hand 1: The Cards Shuffled

I am Kotaro Shirai, and this is my story of legend and war.

A war depicting the fate of humanity and a war of selfish desire.

And somehow, these two wars collide with each other.

And it all starts with my first ever witness of the fight between the rumored masked riders Kamen Riders and the undying beings known as Undead.

Kotaro Shirai, clad in his climbing gear, was traveling through the forests of Fuyuki until the trail he was following went cold and hit a cliff side at the beach. Anchoring a spike into the rocky surface, he rappelled down to the sandy floor to find a cave in the rock wall.

Unbeknownst to him, a blue silver armored dirt biker was riding along the beach side.

All the while, a red silver armored dual horned figure battled a bat-like creature as they exchanged blows before the bat creature punched the armored warrior into the concrete wall leaving a crater as he fell.

Still a ways away, the blue silvered armored figure rode on before his communicator beeped. "Shirou-san, your mark is twenty kilometers southwest." "Roger!"

In a remote location, the video of the red warrior's struggling fight was monitored by a man and woman, "Hurry Shirou-san," she warned, "Tachibana-san is being pushed back." "If you want to save Tachibana-san, you have to hurry," the man pressured.

The rider didn't say anything and just gunned it.

Back to Kotaro, he reached the mouth of the cave and jumped down. And what he saw he couldn't believe. The most he heard from the news were the gas leaks and mysterious murders, the most exciting news anyone got in the past ten years was what was called the Great Fuyuki Fire that erupted suddenly in the middle of town. It left very few survivors.

Very recently there were rumors of these masked warriors dubbed, Kamen Riders combating these monsters that suddenly showed up out of nowhere. Many doubts surrounded these so called urban legends, and now he found proof that these Kamen Riders exist. And one was fighting these humanoid monsters that have been showing up.

Back to the battle at hand, the red Rider was pushing back the bat creature till it summoned a swarm of bats obscuring the Rider's view. His destruction at the bat's hand was imminent till the wall exploded as the blue Rider flew out of the hole on his bike. Between the two riders, the only main differences were the color of the suits, the crest on the armor on their chest, legs, shoulders, and buckle, and the helmets.

The blue Rider held a spade crest on his chest plate, greaves, and spaulders, whilst the helmet based after a hercules beetle whilst the red rider held the diamond crest on his armor where the helmet was based after the stag beetle.

"Tachibana-san, you all right?" "I'm fine Shirou. Just help me take this thing down."

The bat flew and immediately the two riders followed with the red Rider on his own bike with Kotaro immediately following at a slower pace so they don't see him.

The Riders followed a few ways off further into the tunnels till the red Rider pulled out a gun with a diamond emblem on its sides to shoot it out of the air. Firing off a few shots he missed as the bullets ricocheted off the cave walls. He kept shooting and swerved and turned.

In a straight shot portion of the cave, the red Rider took aim and fired, hitting the underbelly causing it to screech in pain and undulate under the wing beats in pain. The blue rider took his spade crested sword from his waist and flung it.

The sword hits its mark and clips the bat's wing dropping it to the ground as the sword embedded itself into the wall. The blue rider grabs back his sword from the wall as they drive up to the creature.

Disembarking from their bikes, the blue rider flipped his sword downwards and pulled on a notch fanning out a set of cards. Taking out the 4 of spades with a bronze armored boar image, he slides it through the scanner and slid it across the edge.

'TACKLE'

The fan closes as the card glows, the boar image glows blue and flies into the armor. As the bat scrambles to stand, the blue rider takes a stabbing pose cradling the edge of the sword; the armored rider glowed and charged. The effort turned futile as the bat swatted him away.

"Shirou-san, you're no match for it. I'll take it on," said the red Rider as he shot the bat several times before pulling a notch from his gun to fan out his own set of cards. Pulling out two cards he took the 5 of Diamond Drop Whale and the 6 of Diamond Firefly and sliding them through the Rouse scanner in the iron sights.

'DROP'

'FIRE'

Flicking off the two cards into the air, they glowed and turned into two glowing images of a whale and firefly merging into the red Rider's armor. Empowered by the cards, he somersaulted in the air as his feet ignited performing a flaming reverse double axe kick connecting with its chest and its head.

Its body spewed green blood raising a green mist overhead as it thrashed around. The stone belt buckle around the creatures waist opened revealing a runic looking 8.

"Category 8, interesting." Taking another card, he took a different designed card which held its category but instead the image held crisscrossing chains and threw it embedding into the beast's chest causing it to freeze absorbing the green mist and blood before sucking in the physical body. Once the body was fully absorbed, leaving no trace of it, the card flew back to the red Rider's hand revealing the 8 of Diamond Scope Bat.

Kotaro, eyes open in amazement in watching the events climb up to its conclusion, just gaped and eyed the card in the red Rider's hand, 'What… what is that card?'

"Shirou, I thought you were taught not to fight blindly," the red Rider, Sakuya Tachibana said walking back to his bike as he pulled the latched onto his buckle revealing the Ace Diamond Change Stag before pulling it out.

"I know," the blue Rider said, "still getting used to this." "Just be careful," Tachibana warned as a blue aura covered the red Rider revealing a 30 something year old.

The blue Rider watched Tachibana walk off to his bike as he pulled the handle on his buckle revealing the Ace Spade Change Beetle as the same blue aura revealed a 16 year old teen with red hair, Shirou Emiya, "I am, but with Taiga-sensei on my back with all this BOARD stuff, I don't want her to get too involved with all this."

Tachibana said nothing as he rode off leaving Shirou to himself putting his bike helmet on. He was about to turn on the engine till Kotaro decided to show himself, "The entrance was pretty cool, but after that, you kind of fell apart there."

"Who are you?" Shirou demanded. "I'm Shirai Kotarou, nice to meet you. I'm an up and coming science non-fiction writer. And you are my subject," said the writer.

"Eh? Subject?" Shirou blinked.

"Well, I've been researching you guys every since those creature started popping up. Legendary men in armor, fighting violent battles against mysterious life forms. A man who walks the path of a Kamen Rider. Way better than those gas leaks that the news have been picking up lately," this guy was as giddy as a kid in a candy store.

"Look I don't know what you're talking about, but…" "I've heard rumors and here you are. Kind of hard to believe you're still a kid."

"Seriously, I got to go. Not to mention, I don't want to be your subject," Shirou said, really wanting to get away from this character, so he turned his key starting his engine. But Kotaro didn't want him to leave as he reached for the key as well turning it off. Both just fumbled with the key till Shirou was able to push him away and rev the engine to life riding away.

Kotaro left all to his lonesome just pouted seeing his subject riding away.

Finally away from that writer, he arrived to the BOARD HQ on the outskirts of Fuyuki. Moving through the sliding doors he made his way to a potted plant connecting his phone to the fake plant/computer ID lock, up the stars palming at the corner support cap as it scanned his finger prints, and finally to an old foreign painting revealing to be a retinal scanner opening the double doors as he made his way into BOARD's lab section.

Inside BOARD's main office, Tachibana was there with one of the female operators, Shiori Hirose, speaking with the President of BOARD, Kei Karasuma, as she asked, "Just what the hell are these Undead?"

"All you need to do is focus on sealing them," Karasuma answered, "We'll do the investigating."

"Investigate, huh?" said Tachibana, "I understand the Rouse Card System works, but…"

"What is it Tachibana?" "There's something I've been debating on. You had me saved pretty quickly. Even brought Shirou here for an 'emergency'," replied the Rider.

"Think I can't do it." "No," the president replied back, "I know you can. But there is a 1 in 10,000 chance."

Tachibana walked off at his boss's answer, but before he got to the door, Shirou tried to diffuse the situation, "Hey, you were still great out there, even after I got there. I'm mean…" "Shirou, what are you fighting for?" "Eh?" the teenage Rider said, slightly confused with the question.

"Why did you become a Rider?" "To protect others, so that no one would have to go through what I did. A Hero of Justice, like my father wanted to be," Shirou answered. "Don't be so naive," said Tachibana shaking his head. Turning to the director, "This is my one warning." With that, Tachibana walked off with his warning hanging in the air.

"Sorry to keep you from your classes Shirou-san. I'll make sure that your teacher knows you're on your way," apologized the director. "Thank you Karasuma-san," Shirou bowed.

Shirou rode through the streets towards Homurahara High School, 'BOARD, Board Of Archeological Research Department, from what I understand it is why mankind has survived for so many years. Some of their research has gone from stem cell research to creating cure for diseases. But when the Undead attacks came, they started on the Kamen Rider project which they invited me as one of their employees under the guise as an intern, the President's idea. Sure this kind of thing is supposed to be secret but I've always wondered, why me?'

'Is it because of my convictions, my relation with Kiritsugu Emiya, my step-father? Do they know that he was a mage, and immediately figured me to have some magic power in me? Wouldn't be completely false, I am somewhat a mage, but all I can do is Reinforce objects and analyze an object's internal structure.'

'But for whatever reason it was, I'm glad that it happened. I don't wish for fame or glory, I just want to protect others as Kamen Rider Blade with Tachibana-san as Kamen Rider Garren. So others don't have to go through what I did. The Great Fuyuki Fire, an incident that happened 10 years ago whereas I was the only survivor. My parents who I don't even remember were dead and I was adopted by my step-father.'

'Upon current events there have been news of these mysterious deaths and gas leaks, it's got me wondering if there is more going on. Gas leaks causing no recollection of anything in the hours before they've been asleep, and the mysterious deaths caused in their homes. At first I thought these were Undead attacks that were under the radar, but the so called 'gas leaks' that left their victims with short term memory loss didn't fit the Undead M.O. and the descriptions of how some of the victims were killed said they we're stabbed rather than horribly mutilated like the other two Undead attacks. So these questions come to mind, are some of the other Undead smarter than mindless beasts, that wish to be left alone, or is there something else a foot?'

Stepping out of his thoughts, he spots the parking area for his bike as well as Kenichi Hayakawa, one of the teachers of Homurahara High as well as an employee from BOARD. "You're in luck; Homeroom is almost over so you'll be able to make it for first period with Mr. Kuzuki. Though Taiga would probably be giving you an earful once she finds you," said the teacher smirking.

"Blame the President," Shirou snapped, "He called me just when I was about to leave school with Sakura-chan." "Ooh, have a little soft spot for the Matou girl?" Hayakawa teased as they walked towards the halls.

"Shut up, you know we see each other as surrogate siblings. Besides, I think she likes that Hajime Aikawa guy better," That was an understatement of the year. Ever since Hajime Aikawa enrolled to Homurahara High at the beginning of the year, Sakura seemed to have this infatuation with him spending a lot of time with the new guy. But whether its love or something else, no one knows. All the while, her brother Shinji would have this dark look whenever he sees the two together.

At first Shirou ignored it thinking it was nothing considering he knew Shinji from Sakura since grade school. But ever since he got that job as an 'intern' for BOARD and trained for the Rider System, he became more aware of Shinji and didn't like what he saw. Bullying around the first-year archery members, pushing his duties to other students, the more he saw of this side of Shinji, the more he realized what an ass he is.

Even some of the harsh words he said to Sakura almost made him punch his that guy's lights out. Well, if Hajime didn't do the deed himself. Ever since then, Aikawa made No. 1 on Shinji's shit list and then Hajime and Sakura became the school's No.1 power couple of the year, the sweet and innocent house wife Sakura Matou with the strong and mostly silent Hajime Aikawa.

'Still, there's one thing that still bothers me. Where did he come from? He just popped up from out of nowhere and I got this unsettling feeling whenever I'm around him. Then again I feel the same around Shinji, but he's just a creep.'

By the time they reached the classroom they see Taiga exit from. And once she spies Shirou from the corner of her eye, "SHIIIIROUUUU!"

The two wince hearing the shrill voice of Taiga as she grabbed the student by his collar shaking him around like a rag doll pouring out the crocodile tears, "Where have you been?! You were supposed to be in class with Sakura-chan! I was so worried!"

Hayakawa sweat dropped and tried to dissipate the situation, "Ah Fujimura-san, his internship called him for an emergency situation. The President called when Shirou-san left for school. Luckily he didn't miss anything yet."

This seemed to calm her down but still left her with a pout, "Okay, but Shirou-san I want to talk to your boss about this 'internment' deal you have with BOARD." "I'll be sure you talk to them. The president is a personal friend of mine. I'll place your concerns to him. Shirou get to class, I'll handle Fujimura-sensei."

Shirou sighs and shakes his head watching his house guardian's antics. Upon entering the classroom, he spots the stoic and serious looking Mr. Kuzuki having the day duty student call out roll call who stopped when Shirou entered the room. Shirou nearly faltered a bit seeing Kuzuki's intensified glare, "Shirou-san, whilst I'm glad to see you in class, please make sure the next time you're late you would come in from the back entrance quietly so you wouldn't interrupt."

"Ah ha, yeah, I'll make sure, next time," Shirou sweat dropped walking to his seat.

By lunch period, Shirou made his way through the halls till, "Shirou-san!" Turning around he found Sakura towing around Hajime. "Ah Sakura-san," "Where were you? You missed homeroom," Sakura asked worriedly.

"Sorry, my job had me come in for an emergency," Shirou answered scratching the back of his head. "You should be more careful Emiya-san," spoke Hajime in a dangerous tone, "Someone like Sakura shouldn't be left alone like that."

The words dug deep in Shirou as he cringed at Hajime's tone. It reminded him of Tachibana earlier this morning. "Hajime-san, don't heckle Shirou-san like that. To be interning at BOARD must be taxing, plus with Shirou's experience with machines it's understandable for him to be called to work like that," chided Sakura slapping him lightly on the shoulder.

"Sorry, but he should have been more mindful," said Hajime, lightly glaring at Shirou.

"Ne, Shirou-san, have you heard of the urban legend that's been going around lately," Sakura asked changing the subject.

"Hmm, 'urban legend'?" 'Could she be talking about the …?'

"Lately there have been strands of violent murders in public to go along with the recent killings in local households. But instead of a weapon, these people seem to have been murdered by an animal or something. Some people who said they saw the murderer says it's not a person at all, but some kind of two legged animal monster."

'Undead.'

"But as soon as these monsters acted, these armored warriors came into action. I believe they were called Kamen Riders."

"Kamen Riders?" Hajime asked.

Sakura nodded in confirmation, "Heroes who fight for humanity. Like knights in shining armor protecting the people. Almost like King Arthur."

Shirou smiled at the thought, it almost matched his legend, "Kind of sound like him."

The two shared a laugh not noticing Hajime who seemed to look blankly at the floor, 'Kamen Rider…' What are these words? 'Kamen Rider…' Why do they sound…?

His breathing became slightly labored, enough for Sakura and Shirou to notice. "Hajime-san, are you okay?" Hajime stumbled to his knees causing Sakura to cry out in alarm, "Hajime-san!" Her outburst was just loud enough to catch everyone's attention. "I'm alright Sakura-san, just a little dizzy," he answered in attempts to calm her down.

"Let's get you to the nurse's office right now," Sakura insisted. Hajime was about to object but he just couldn't, not to Sakura anyways. "You should listen to her," Shinji piped up, "Once she makes up her mind, you can't make her change it."

Sakura lifted him up to support him onto her shoulder, "I'll see you later Shirou-san." "Yeah, see you later. I got to get to Issei-san anyways," Shirou smiled back making his way to the Student Council room leaving him to his thoughts, 'Looks like me and Tachibana-san are pretty famous, we should watch ourselves if it's like this.'

His thoughts came to a pause thought as he saw another female student, and her red outfit isn't the only reason why he knows her, it was mainly her reputation. 'Rin Tohsaka of class 2-A, nothing really bad about her. Good grades, beautiful, and lots of flattering rumors from the male student body. Nearly every boy in the school is gunning for her. Just a perfectly normal average school girl.'

'To the untrained eye. After working with BOARD, you find normal to be just as bad as the abnormal. Because I've noticed outside of her group assignments and school, she's not the most sociable person. Maybe I'm over thinking it like Hajime-san. Too many hours with BOARD probably made me a bit paranoid, I'm already paranoid with Taiga-sensei. But still, maybe it's just me; it just feels like there's more to Tohsaka-san than meets the eye.'

Hours Later

The Emiya Estate was a fairly rustic looking home you see some of the more traditional rich Japanese families live in. But considering his legal guardian, Fujimura Taiga, is the granddaughter of Raiga Fujimura who was one of Kiritsugu Emiya's acquaintances and land manager.

Luckily, Taiga is usually gone at night and he has the house all to himself until the morning. Taking his bike to his shed he spies an old outdated heater put there by probably one of his friends from the student committee. "Well, better get started on it."

In a small restaurant café, the Jacaranda, Hajime and Sakura helped clean the dishes after closing hour. When Sakura first met Hajime, she liked to know where he stayed. The small restaurant café was owned by Haruka Kurihara and her 8 year-old daughter Amane.

Like Sakura, Amane liked Hajime, and while the girl may be a bit jealous with the older girl, the two hit it off were like sisters. Haruka liked to see these two get along and even asked if Sakura wanted to work at the Jacaranda part time.

But Sakura was slightly reluctant; something Hajime noticed was slightly uncharacteristic of her before realizing it was her brother Shinji. Hajime spoke to Shinji, what it was most definitely spooked the arrogant teen, mostly explaining why he's No. 1 on his shit list, but it allowed Sakura work at the Jacaranda with Hajime.

Currently Haruka's brother Kotaro, an up and coming writer, was sharing his tale of meeting a Kamen Rider. Apparently he heard some rumors about them as well.

Sakura passed a cup of tea to Kotaro as he mentioned his failure to find a publisher. "Aw, sorry to hear that," apologized Sakura. "It's alright, I've already found a new inspiration," Kotaro grinned. "You mean the Kamen Riders?" "Yep, and I've already got the book down," Kotaro bragged.

Unnoticed to the rest, Hajime stumbled again, fortunately he caught himself so he wouldn't bring attention to himself, 'Kamen Rider? Why? Why does that name affect me so much?'

"Hajime-san, are you okay?" Sakura asked concerned. "Yeah," said Hajime shaking head, "just need to rest. I'll be in my room."

Rushing back to his living quarters, he slams the door shut as he gasps for air.

Kamen Rider

What is it?

Kamen Rider

What the hell is it!?

From his person, a card fell from his coat. It's looked like a playing card. An Ace of Hearts, the Change Mantis rouse card the image depicting a mantis encased in a crystal heart. As soon as he laid eyes on it, visions of a red and black armored figure flashed for a split second as he slammed his fist to the oak door struggling against some sort of inner battle within him.

Evening

A dark room surrounded one Rin Tohsaka as she holds a book of old magical origin the circle below glows as she chants the following spell.

"I command thee, thou shalt come to my side. Thy sword shall control my fate. Abiding by the Holy Grail's haven. If thou accedest to this will and reason, then answer me. The oath set forth here. I am the embodiment of good in the eternal world. I am the disposer of evil in the eternal world. Thee the seven heavens that bear the Great Trinity. Come forth the circle of constraint."

And with a drop of blood, it splashes onto the circle causing it to rise and spread.

"O guardian of the balance."

-BOOM-

Shirou suddenly jolts from his sleep, tired spending the rest of his afternoon working on the heater when he hears his phone ringing.

Letting out a yawn, he picks up the phone and brings it to his ear, "Hello?" only to be greeted by frantic cries.

"Shirou-kun! BOARD is under attack! Please hurry!"

"I'll be there soon."

Grabbing his helmet, he heads back to BOARD. Someone or something had attacked HQ; hopefully things aren't as bad as it sounds when he gets there.

Rin runs through her hallway just to find what that explosion was.

Did the spell work? Was it a dud? Hopefully she got something.

Opening the door, she got her answer. A dark skinned man in black body armor and a red coat with snow white hair. He just sat there so casually ignoring the destroyed furniture in the room as he sat with his leg crossed over the other. "My, my," he spoke, "I certainly got picked by a wonderful Master."

She just stared at him with a pout.

Shirou finally got to BOARD hearing its security systems blaring its alarms, spotlights swerving around to find its culprit for its attack. He rushed in with no hesitation finding the whole building filled with grasshopper everywhere. Running through the labs, he found bodies everywhere.

It was horrible, everywhere he looked, dead bodies and destroyed equipment and years of research. Finally he made it to the command center and found it just as destroyed and filled with death as well. Shirou grit his teeth; it was just like the Fire ten years ago. Flashes of the Fire enter his mind, many different bodies surrounding his own near-dead body. He promised himself that something like this would never happen again, the massacre of dozens and hundreds of people.

But when a nearby door banged, the door was stuck behind some debris and someone couldn't get out. Shirou was glad, a survivor.

Pulling onto the door, he found Hirose. Alive, but bleeding, at least the wounds weren't serious. "Hirose-san, are you okay? What happened?" "The Undead. The Undead just attacked us," Prepping herself up to the wall, she kept talking, "Tachibana, I think I saw Tachibana-san controlling it." "Tachibana-san!? Why would he do this?" he couldn't believe it, why would Tachibana attack BOARD. Was it from what he said earlier this morning?

"I heard Tachibana-san and Karasuma-san arguing, and from what Tachibana said, sounded like he was threatening BOARD," "What do you mean? What exactly did he say?"

She opened her mouth, but what she had to say died as the windows shattered open as a swarm of grasshoppers flew out the door. Seeing the enemy, Shirou followed after it ignoring Hirose cries.

The swarm led him outside before they merged together creating a solid body, a humanoid Grasshopper Undead.

"Found you," pulling out the Blay Buckle and Category Ace of Spades, he slipped the card into the buckle. With the card inside, red cards flew out one slot around his waist and into the other end of the buckle. The object chimed and hummed as Shirou placed a hand on the handle, "HENSHIN!" he flipped the buckle revealing a golden spade. The Grasshopper charged ignoring the blue field of the beetle emerging from the buckle getting knocked on its backside as the field collided with the Undead.

With a battle cry, Shirou charged through the field changing into the Blue Rider of Spades, Kamen Rider Blade.

"So you don't know anything about your name save for your servant class?" Rin asked taking a sip of tea her 'guest' had made for her.

"Yes, since the summoning spell you casted had somewhat backfired, I have no recollection of my past life," said her 'guest' indulging in some tea himself. Rin pouted somewhat at the shot at her magecraft, even if it was true. Upon enacting the ritual, she had tried take account all factors before the summoning, more specifically, the moon by which she assumed was a full moon so that her powers would be at its peak.

Unfortunately, her overconfidence in her abilities and her lack of timing cost her Servant's loss of memory and her living room.

But Rin always knew how to make a positive out of a negative, "Okay Archer, while I might not know your true name, neither will the enemy so your weakness or weaknesses are potentially safe."

"I'm sure they won't," Archer smirked taking another sip of tea. "Hmm," stopping mid-sip Archer's attention turned to the nearest window on the right. "Is there something wrong Archer?" asked Rin.

"Someone's fighting," Archer answered. "The Command Seals aren't reacting, so why should it concern us?" Rin asked indignantly. "Because who or whatever is fighting is using a powerful and old mana source," Archer answered.

"Should we be worried?" she asked curiously. "It's not a Servant or a Master, but the mana is coating someone in it," said the Servant.

"Let's go," she ordered grabbing her red coat, "it's the dead of night so nobody should be able to see us. But in any case, be prepared." "You don't even need to ask," he smirked grabbing her waist, "Hang on."

Blade pulled out his Blay Rouser in an underhand hold and slashed at it causing sparks to fly. Holding it in a proper stance, he swung his sword in an overhead swing. The Grasshopper Undead jumped back and dodged. Stepping forward he thrust but the sword was swatted away. A battle cry followed the wide cross swipe.

Rage and sorrow filled his actions. A comrade's betrayal and the slaughtered people he came to know here in BOARD, he knew most of them had loved ones. Whilst the attacks were strong, Blade's swings were wild and uncontrolled. Many close calls towards the Undead, but they kept being blocked and kicked away.

The Undead threw a roundhouse kick breaking through Blade's defense. Blade recovered and retaliated with another roar followed with wide right swing. The Undead caught the sword and booted the Rider with a forward kick launching him several feet away.

Blade flew and tumbled to his back. His breathing slightly ragged, off the corner of his eye he sees Garren just watching the match go by as Blade rolls away to dodge a hard stomp from the Undead avoiding his head from becoming a crater.

"What's going on here?" asked Rin watching the events unfold. Rin and Archer was able to find the disturbance easily from the spotlights and the alarms blaring from the BOARD building, they were able to find a hiding spot in the forest nearby, Rin on a branch hidden behind the bushes of the trees while Archer stayed on a broken lamp post. She couldn't believe it, before her was one of the rumored Kamen Riders she heard from her classmates talk about and these…things.

It was some sort of humanoid grasshopper; she hasn't seen anything like it. And the mana signature, like Archer had said, it was old but powerful. And both were radiating in it, the armored figure more so than the bug. But somewhere, she sensed a third signature. But she couldn't pinpoint where due to the fighting going on. The air smelled grassy like the bug creature and its mana was everywhere in the area.

"Archer, you have an idea what that thing is?" Archer didn't say anything and frowned, something about these things he didn't like. It wasn't a dark magic feeling, but it was still ominous.

"Archer," Rin whispered seeing her Servant just watching the fight. "Archer!" Rin slapped the white haired Archer on his armor catching his attention, "I asked you if you had an idea on those things?"

"No, like I said, the power they hold is old. If I had to guess, the magic is about as old as or older than the First," Archer surmised. "O-older than the First Magic," Rin repeated incredulously. Something like that that was older than the First magic, was creation of life, within God's territory who made the first humans, i.e. Adam and Eve.

Just what are they dealing here?

'Why is he just watching?' Blade thought throwing a right hook at the grasshopper before blocking its swipe with its clawed hands.

'Are you really a traitor?' thoughts clouded his ability to fight when he blocked a punch to receive a kick in the gut and knock him down.

Walking to his side, the Grasshopper Undead reared its leg again and kicked his stomach causing his eyes to bulge under the mask launching him to the tree nearby. If he wasn't in Rider form, this would probably have killed him from his spine breaking. But his mind wasn't on the pain or on the Hopper's foot over his head, but rather on Tachibana, a comrade, a teacher, a friend.

And now he's traitor.

Why?

'Why did you betray us?'

"BLADE!"

The motor of a motorbike rang throughout the area as a black Honda X250 rocketed with N0S flames from the exhaust pipes into the Undead pushing it away from Blade. A gunshot echoed in the area and blew up the bike engulfing it in a ball of flame.

Looking up from his back, he sees a figure in black biker gear with a shining matching biker helmet holding the smoking shotgun in hand.

"Remember your training, mission first, then your personal problems," said the biker pulling the Rider back to his feet. "Hayakawa-san?" The biker scoffed flicking open the visor, "That's 'sensei' to you."

"How did you-?" "I was grading papers at the time when Hirose-san called me. I gunned it as soon as I got the message," Hayakawa explained as Blade retrieved his Blay Rouser.

The clicking hiss of the grasshopper sounded through the crackling fire. "Listen, we don't have time before that thing recovers. Take care of the Undead and I'll get Hirose and any other survivors, if there are any."

"But Tachibana…" "Remember, mission first, personal problems later, got it," Hayakawa said sternly. Blade stared into his eyes and saw the seriousness in them, "Right, take care of Hirose-san." "Good luck."

Hayakawa dart towards the wrecked building when the Grasshopper Undead jumped out hissing angrily. It passed Blade and jetted towards Hayakawa, "Dammit!"

"Archer, help him," Rin commanded. Archer nodded as he summoned a night black bow. Pulling back the bowstring his hand filled with mana as it glowed forming into a-

"TACKLE"

"Wha-?"

Before the Undead could land on Hayakawa Blade bashed into the Grasshopper sending it flying as he glowed in the translucent aura of the 4 of Spades Tackle.

"Go!"

Hayakaya nods in confirmation and bolted into the building. Blade held a kendo stance whilst the Hopper got back on its feet. 'Focus on the mission. Tachibana will be dealt with later.'

The Hopper charged once again and swung with its left claw as Blade parried the offending appendage away. Right claw, same result. Side kick with its left leg and Blade swatted it away with the butt of his weapon sending a round-house kick of his own. It wasn't as powerful but it caused the Undead to stumble back. With his mind clear, his actions were proper and effective.

Recovering from its stumble it hunched over to all fours whilst its legs contorted and turned into actual grasshopper legs. All the while, Blade turned over his Blay Rouser and fanned out his cards again pulling out the Category 2 of Spades Slash Lizard. Off to the side, Garren was gone. He couldn't let his mind wonder, he had to keep it on the battle.

He barely had time to slide the card through the rouser scanner as the Hopper launched itself to Blade.

"SLASH"

The sword he held edged and sharpened as it glowed with the Category 2's power. Blade attacked with an underhand slash at the rocketing Grasshopper as it collided with the Rider and into the nearby wall behind him leaving a web-like cracked crater into the wall.

Blade was damaged with the full force of the attack, but so was the Undead as it fell to the ground with Blade following behind as he plopped to the grassy earth as well.

The Undead was the first to get back on its legs before it succumbed to the Slash card's effect and spewed green blood from the split wound through its torso and head. Heavily damaged from the last attack, Blade was able to bring the strength of one more deed. Pulling out a Seal card he threw it towards the wounded insect as it was absorbed into the card before flying back to Blade.

"BLADE!" Hayakawa called out pulling up in an army green jeep with Hirose on the passenger seat as Blade succumbed to his wounds sustained from the battle falling face first.

"Hirose-san, get his legs and get him inside," Hayakawa instructed as he pulled on the Buckle turning him back into Shirou's civilian form sporting a few bruises and cuts here and there.

Pulling him inside the back seat of the jeep, Hayakawa drove off from BOARD HQ leaving their dead comrades. All the while Archer and Rin fled in the dead of night with Rin contemplating the events that has transpired here and Archer with his own thoughts.

Driving the streets of Miyamachou side of Fuyuki, Hayakawa with his helmet off took a quick glace to the back seeing Shirou trying to be nursed by Hirose, "Hirose-san, how's Shirou?" "He's fine, actually he's amazingly healed about half-way," Hirose replied with surprise in her voice.

"You must be an amazing nurse," Hayakawa smirked. "No, he's half way healed and I didn't even start on him. The bruises are fading and the cuts are stitching themselves together, not even a scratch," Hirose informed him shocking the driver.

"The hell, how is that possible? The wounds he had should have lasted for days. That kind of healing only exists in comics," Hayakawa states pulling up at the Emiya estate. Popping open the passenger side he gets a good look at Shirou, and true enough, all the wounds sustained after the battle were gone.

'Who the hell did Kiritsugu pick up during the Fire?' "Get yourself settled in the guest room Hirose-san, it's in the hall 4 doors down. I'll get Shirou in his room," Hirose nodded and started grabbing her supplies she packed from BOARD.

As Hirose unpacked, Hayakawa picked up Shirou in both arms walking towards the Estate's corridors. 'Hard to believe it's been 5 years, days before the Fire since I've been here.'

*Flashback*

Emiya Estate

"You called me here Emiya?" a young Hayakawa asked.

Kiritsugu in a dark brown kimono slowly nodded, "I needed to speak to you. This might be the last time I may be able to do so."

The mythologist quirked an eyebrow at the response, "What are you talking about?"

"I'm dying and I don't have much time. At most I estimate at least a day or two," Emiya informed him grimly. "Dammit," Hayakawa scowled, "It was the Grail wasn't it?"

"Yes. I knew it after the fourth War had ended that I was on borrowed time. A curse from the Grail when I realized that it has been corrupted," said Kiritsugu taking a sip of tea, placing it on his palm, his friend could easily see him trembling. About as bad as he said it was.

"Tch. I assume you didn't have me come here for a little talk just to tell me you were dying," Hayakawa smirked.

"I had a talk with your boss, Kei Karasuma," Hayakawa's smirked disappeared, "He came by and told me of the incident that happened a few weeks back including those cards you found."

"He did huh? I'm gonna assume he offered you a job to help take care of them."

"Actually he offered me a position as a user for the Rider System BOARD has been developing."

"No doubt you didn't take it due to your current condition?" Hayakawa asked worriedly.

"Actually I considered Shirou for the job in the near future," Kiritsugu said bluntly. "Are you kidding me Emiya? After what that kid went through, he should be having a normal life," Hayakawa argued.

"I've been training Shirou in a few bits of magecraft, much to my disapproval, so he should be ready by the time the system is operational," Emiya countered, "besides, I've made a few enemies in my life. I don't doubt that they would take it out on Shirou."

"Especially those Einsberns, I actually forgot about that," Hayakawa sighed, "What did you train him in?"

"Analysis and Reinforcement."

"You're kidding me. Five years and that's all you've been teaching him," Hayakawa said incredulously.

"I can't do much to teach him except a few fundamentals which doesn't need an example to teach since my magic circuits have been fried. But I made sure he stays safe," the Emiya patriarch says vaguely, "And I want you to keep an eye on him so he doesn't stray from his path."

"'Stray from his path'? What is that supposed to mean?" "I got a good look at some of the cards that were saved and despite my disability I can sense the prana radiating off of them. It's old, real old," Kiritsugu speculated.

"I know, I dated them myself to about 10,000 years. But what is it about these old cards?"

"Old magic is sometimes so powerful that they don't decay and they can't be stopped by normal means, they can only be sealed," Kiritsugu explained, "And that's what those cards are, sealed powerful magic. This sort of power can tempt man.

That's why I want you to promise me to take care of him when I'm gone. Make sure he doesn't give into the temptation of power."

*end flashback*

"Shirou is far from temptation as far as I can see, but dammit Emiya, just what the hell did you do to that kid?"

Tohsaka Manor

While Archer is keeping watch from the outside the Tohsaka Estate, Rin herself was franticly looking through her books. Her father's library was a mess and her hair disheveled she couldn't find anything, "ARGH, DAMMIT! Nothing, hundreds of books in my father's study and nothing about these damn creatures."

"They have to be Homunculi, but who else besides the Einsberns know how to make Homunculi. They specialize in making artificial humans not these humanoid monsters," its 2 hours well past midnight, and Rin's eyes were starting to tire.

"And that armored warrior, at least he looked human when they removed that armor, but who was he and his accomplices. Do they have something to do with it? They must have something to do with those creatures; otherwise they wouldn't have taken the time to seal it in that card. It's hard to believe that an archaeological company has some dabbling with magic," her eyes strained across the bookshelves and revisiting them, tiring eyes landed on her father's old journal on the desk of her father's study.

'This may be what I'm looking for,' *YAWN* "Better go to bed, wouldn't want to mar that perfect student outlook in school now. Archer," Rin called out. Immediately, Archer appeared to her side answering her call, "I'm going to bed now, be sure to watch the place, it may be early, but there may be other servants that have been summoned. Plus with those 'things' out there we can't be sure."

"Of course Master," Archer complied watching his Master walk towards her bedroom.

'That armored warrior was a kid, more than likely it was 'him'. If his armor is powered by those cards he's been using, then every being like it he defeats will make him stronger. Hopefully he can be taken care of before he gets too strong on his path.'

I'm gonna try and not plagiarize the whole of both series and kinda make a new path.

So yeah, I'm gonna do something a little different. Few issues from Blade and FSN will be the same, but the ending may change, hell, I may do multiple endings.

Hayakawa's profile is up on my Profile, just so you can get an idea on what he looks like or ignore it and imagine him yourself.

KR Blade fans will know Tachibana and Hajime as cannon for Garren and Chalice.

But as for Blade and Leangle, Shirou as you see is Blade with a slightly different attitude and lifestyle. I'm gonna try and make him less naive about Shinji cause, really, we hate that impotent prick. Leangle is gonna be a FSN character, guess if you want, but it might be kinda obvious.

Also, I had to do a lot of research since I haven't seen or played the visual novels, just the anime and manga of FSN, Fate/Zero and Unlimited Blade Works(see where I got the name, huh). But if I got anything wrong with my information, PM me or review.

And if anyone is an artist out there, can someone please photoshop or draw something that can combine Blade and Fate/Stay just right. This is purely optional, but I'm a suck ass artist, so if no one takes the challenge, I'll just pick up something from the online search results. Put it up on Deviant Art because I got an account on DA, send a PM with the name of the art piece and your DA name if its different from your Author's Name, if you don't like DA, PM me the site with the other stuff I just mentioned.

Until next time
