Hello everyone. I found an interesting crossover of Touhou and Fate/Stay Night that's 3 years old and only has 2 chapters so far. I asked the creator if he's leaving for adoption and he gave me his permission to use his idea. The Original title is Scarlet Blades made by SuperNova23, so give him credit. Some part of the story will remain the same and the rest will be alter to be my own. Hope you like this Fanfiction
Disclaimer: I do not own Touhou or Fate/Stay Night


Summoning of Scarlet Devil

There was once a time when Earth was abundant with magical engery. All sorts of divine creatures and phantasmal beasts existed alone with humans and the animal we know today. Magic was practiced by many and magicians were plentiful. This was the Age of the Gods, where Magic was time however, technology advanced, replicating feats that once were impossible without Magic. These once-magical arts were reduced to the lesser art of magecraft, and the Age of the Gods began its decline. People began to lose faith in the gods and creatures, and without faith sustaining them, the gods cannot exist. This was the beginning of a New Age. An age where mankind was a god, the Age of just because Earth lost its capacity for magic and unable the hold god does not mean that other places have. For example, a pocket-dimension will have a separated influence away from earth's magic downfall and there is one existing till this day. Within this pocket-dimension protected by the Great Hakurei Barrier, exist a world where the Age of Gods is at its peak. The levels of magical energy have not decrease and magic surpass or unable to be replicated by technology. This is the land of the Eastern Wonderland, the small world known as Gensokyo.

But just because Earth lost its capacity for magic and unable the hold god does not mean that other places have. For example, a pocket-dimension will have a separated influence away from earth's magic downfall and there is one existing till this day. Within this pocket-dimension protected by the Great Hakurei Barrier, exist a world where the Age of Gods is at its peak. The levels of magical energy have not decrease and magic surpass or unable to be replicated by technology. This is the land of the Eastern Wonderland, the small world known as this wonderland, there was a red European-style mansion nestled into the woods by a lake. The gate to this mansion was guarded a Chinese woman, who stood tall, but as the same time was fast asleep. This is the Scarlet Devil Mansion. And the owner of this mansion was the aforementioned Scarlet Devil. Along with her sister, maids, and her librarian friend, who she currently having tea with.

In this wonderland, there was a red European-style mansion nestled into the woods by a lake. The gate to this mansion was guarded a Chinese woman, who stood tall, but as the same time was fast asleep. This is the Scarlet Devil Mansion. And the owner of this mansion was the aforementioned Scarlet Devil. Along with her sister, maids, and her librarian friend, who she currently having tea with.
"So, how has your health been lately Patchy?"The one who spoke was the Mistress of the mansion, Remilia Scarlet. She was short and flat, looking like a girl no older than eleven. She was dressed in pink and had a mop of blue hair on her head. On her back protruded small bat wings.

The person she was speaking to was Patchouli Knowledge, the librarian and one of the best spell casters that existed. She had long purple hair and wore a violet nightgown. She was often very pale and sickly. 'Bet it's because she never takes a step outside this dusty library' Remilia thought as she sipped her tea.
Patchouli coughed as she began to reply. "It's been better lately. If it stays this way, in a few days I might be asking you to a Spellcard duel." Remilia smiled at this. Patchouli, despite all her power, wasn't able to battle often because of her health."Well then, I'd best not impede your rest then. Take care." She set down her empty tea cup. "Sakuya!"

"Well then, I'd best not impede your rest then. Take care." She set down her empty tea cup. "Sakuya!"
The silver haired, who looked like a girl in her late teens, seemingly appeared out of nowhere. "Yes, Ojou-sama?"
"Clean up the tea set and fetch my parasol. I want to go see the Hakurei Shrine Maiden."
"I'm afraid that's impossible," The head maid said, picking up the tea set. "One of the fairy maids saw her heading to the Forest of Magic."
"No doubt to meet with the book thief." Patchouli muttered. Remilia paid her no mind, simply set her face in a pout. While she was a five-hundred year old vampire, she was rather childish. "So there's nothing to do?" She whined.
"If you'd like, I could assist you as soon as I finish the day's work."
Remilia's pout faded. "Thank you Sakuya. I'll be waiting."An hour later, Remilia sat on the balcony watching the courtyard with her parasol next to her. She sighed as she watched the fairy maids go around and take care of the gardens. She was desperate for something to entertain her. As she pondered this, she took her strand of fate. She quickly altered the thread of fate. '

An hour later, Remilia sat on the balcony watching the courtyard with her parasol next to her. She sighed as she watched the fairy maids go around and take care of the gardens. She was desperate for something to entertain her. As she pondered this, she took her strand of fate. She quickly altered the thread of fate. 'Make something interesting happen to Remilia Scarlet'. Something so vague on her thread of fate was dangerous, but she was desperate. As to what would interest her, she let the thread go, letting the powers at be decide who she ended up tied to.
She felt the thread of fate anchor itself on something, and drew her away. As she disappeared, Sakuya was walking out to the balcony. Seeing something as impossible as seeing her mistress simply disappear stunned the perfect elegant maid into dropping her silver tray and just stare.


[Gensokyo, SDM]
Sakuya stepped out into the balcony just as Remilia began to disappear. She froze time watching in total shock, but even in the frozen space, her mistress simply vanished. The Perfectly Elegant Maid stood in the frozen space until she composed herself. Once that was done, she set out for the library. She would do everything in her power to bring her Mistress back safe and sound. The library wasn't the best source, but it was more readily accessible than any other source.


[Emiya's Resisdence]
Shirou spat out the toothpaste in his mouth and wiped his face. He was about to climb into bed when the doorbell rang. The red-haired boy walked to the door and opened it only to find of the strangest and most terrifying sights he had ever seen. On his doorstep was a small hair with red eyes and snow-white hair. She couldn't have been more than eleven. She had on a dark violet blouse and a long white skirt. Behind her stood a massive main with one yellow eye and one glowing red eye. He had a wild and unkempt hair and skin the colour of lead. All he had on was loincloth and both figures radiated an aura of sheer terror.
"Are you Shirou Emiya?" The girl asked, a little too sweetly as she smiled up at him."
"Y-Yes, I am." He replied hesitantly.
"It was a pleasure to meet you." Her face became deathly serious. "Berserker!"
He had already taken running before he heard her next words.
"Kill him."

Shirou didn't stop running. Even then, the monster, (what had she called it, Berserker?) was gaining on him. He heard it crashing through walls, support beams, anything to take the quickest path to Shirou. As he ran through the house, he saw a kendo stick out of the cornor of his eye. He knew he couldn't outrun him, so he dove to the side grabbing the knew a bamboo sword, no matter how it was treated, would be useless against the monster after him. But Emiya Shirou wasn't an ordinary boy. He was a magus, a pretty awful one at that. He held the stick tightly in his hands.

He knew a bamboo sword, no matter how it was treated, would be useless against the monster after him. But Emiya Shirou wasn't an ordinary boy. He was a magus, a pretty awful one at that. He held the stick tightly in his hands."Trace on."

"Trace on."He felt the elements that made up the bamboo

He felt the elements that made up the bamboo stick, and carefully altered it so the bamboo stick was much sturdier, like a steel pipe. It was just then that Berserker burs through the wall, the girl close on his heels. She looked at him as if the idea of him trying to stand up to her beast was just a good joke. "He wants to try and fight? That's cute. Berserker!" She snapped her fingers to call its attention. "You can play with him for a little bit."
If it could express any emotion other than anger, it would have expressed joy at the ability to play with Shirou like a cat with a caught mouse. Except in this case, Shirou was the mouse and Berserker was a cougar. Shirou barely saw it move, but with a single strike, he was sent hurtling through the wall with a broken bamboo stick, through the shed door, and eventually the back wall stopped his momentum. It only took a few seconds before he saw the girl's creepy red eyes in the doorway, her silhouette not made any less creepy by her beast behind her. He tried to move, but every muscle and bone in his side screamed in protest. He spat up a little blood as the girl pouted."Too bad. Looks like our game's done. Berserker!" As it stepped forward, a magic circle under Shirou lit up with a blue light, and beside him appeared a young girl with blue hair and bat wings, dressed in all pink. He cried out in pain and felt a burning sensation as marks burned themselves into the back of his right hand.

"Too bad. Looks like our game's done. Berserker!" As it stepped forward, a magic circle under Shirou lit up with a blue light, and beside him appeared a young girl with blue hair and bat wings, dressed in all pink. He cried out in pain and felt a burning sensation as marks burned themselves into the back of his right girl turned to face him, taking in the new world around her. "I didn't expect the threads of Fate to call me to the Outside World. It's been so long!" She looked down at Shirou. "I am the Servant Lancer. Now answer me, are you my Master?"

The girl turned to face him, taking in the new world around her. "I didn't expect the threads of Fate to call me to the Outside World. It's been so long!" She looked down at Shirou. "I am the Servant Lancer. Now answer me, are you my Master?"


Remilia marveled at the world around her. It's not easy to cross the Great Hakurei Barrier without a certain Gap Youkai's permission to go out to the outside world. How long has it been since she was last here in the outside world? At least a century, if not more. Still, her curiosity could wait. She had been summoned by the Holy Grail to compete in a war for it, and all the necessary information had been forced upon her as she was being summoned. That was quite helpful. She looked down at the red-head next to her. The words she said felt as if she was reading a speech prepared by someone else. "I am Servant Lancer. Now answer me. Are you my Master?"He looked back in confusion, so she just grabbed his hand, seeing the Command Seals, she sighed. "Well, you summoned one of us. And since I doubt you summoned the monster over there, let's say for now you're my Master until you can properly speak."

He looked back in confusion, so she just grabbed his hand, seeing the Command Seals, she sighed. "Well, you summoned one of us. And since I doubt you summoned the monster over there, let's say for now you're my Master until you can properly speak."
Remilia's first priority was to get rid of that monster. It was massive, and the wasn't sure even the Hakurei Shrine Maiden could put a solid dent in it with her Danmaku. So she began weaving a new strand of fate. "Miss, where I come from, it is common courtesy to introduce yourself before trying to kill someone. Could you at least grant me that courtesy?" Not a total lie. Flandre always wanted to know the names of fairy maids sent down to clean her room. She lost so many good maids before Sakuya did it herself….The girl seemed taken aback, but smiled. "Well, then Lancer, if you must know, I'm Illyasviel von Einzbern, and this is Berserker." Perfect. Now she could weave the strands of fate between her Master and her. It was fairly simple, so she had almost finished trying the knot before Berserker charged her.

Now she could weave the strands of fate between her Master and her. It was fairly simple, so she had almost finished trying the knot before Berserker charged her.
In a flash, her blood-red spear was up, held in two hands, her vampire strength barely holding back Berserker's massive sword-axe. She quickly scanned her area. She was in a small room, with no space to dodge left or right. With the roof over her head, she couldn't fly up, and even if she did, Berserker would swat her out of the sky like a fly. Then she saw Illyasviel totally unguarded. She could solve this problem quickly, but she only had one shot. She took a deep breath and removed one hand from her 's weight toppled down on her as she removed her hand and moved aside, making a noticeable dent in the floor as a stream of red bullets came out of Remilia's hands.

Berserker's weight toppled down on her as she removed her hand and moved aside, making a noticeable dent in the floor as a stream of red bullets came out of Remilia's hands. As she fired, she felt the lack on natural magic, and how she was pulling off her own reserves. Using her Spellcards would certainly be harder here than in Gensokyo, she thought as the girl screamed and Berserker ran away to cover her.
Berserker was crouched over the girl, who had a scorch mark on her sleeve, that her danmaku had missed and damaged her sleeve. Her simple pellets harmlessly bounced off Berserker's skin. Seeing Remilia's shock, the girl laughed. "Berserker's not any normal Servant, he's the great Heracles!" Remilia nearly choked right there. She was born in Europe, so she knew the fairy tales and stories of her time, and of course she knew the legend of Hercules, the Roman name given to Heracles. The girl continued, "And as you can see, normal attacks can't hurt him!"
Remilia quickly weighed her options. Berserker's back was turned, so she could impale him. Possible, but if the myths were true, she'd likely only increase danger she was in. She could use her Noble Phantasm, but that would simply just show to other Masters what she could do while questionably killing Berserker. So she went with her third Berserker stood up, she finished tying the threads of fate she made. "Master, what's your name?" She asked the redhead, who had been too shocked to move. He seemed to snap back to reality at her words. "Em-Emiya Shirou!" She slipped he name into the knot and it was complete. She could have used "Master of Lancer" and "Master of Berserker," but real names was much easier to work with and gave better results. She then let the thread go and act itself out.

She could have used "Master of Lancer" and "Master of Berserker," but real names was much easier to work with and gave better results. She then let the thread go and act itself out.

"Illyasviel von Einzbern leaves Emiya Shirou and his Servant, and will wait a week before approaching him with hostile intent."
It would have been much harder to make her stay away forever, since she clearly had a killing intent, so a week was the most time she could put in without this girl trying to challenge the fate. That was the funny thing about fate. If you knew it was in effect, you could challenge it.
It seemed to have worked though, as Illyasviel yawned. "This is borning. Come on Berserker." She said, walking away. Berserker simply disappeared into thin air. Before she walked away, she said, without turning around, "And don't try to shoot those red pellets at me. Try it, and I will have Berserker Kill you right now." 'Right, no Danmaku then.'

As she left, Remilia went to check on her Master. The pain had caught up with him and he had passed out. She picked him up and carried him inside to rest. Normally, as a vampire, she couldn't enter one's home without their permission, but since she had summoned onto the Emiya Property, it counted as being searched high and low for a proper bed, but she couldn't find anything resembling a mattress. "Where does he sleep?" She asked herself, before spying a futon. "This look likes what Reimu uses…" She said, before lying him down. Now Remilia was no doctor, but he wasn't bleeding, so she decided to wing it. He wasn't going to die overnight. Her first order of business was to find some way to fix this place up. Unfortunately, she lacked any maids. As she began to look for material, she sighed. "I miss my fairy maids so much right about now…"

[SDM, Scarlet Library]

Sakuya walked into the library. "Patchouli-sama, we have a problem." The anemic witch just looked up as Sakuya continued, "I'm in need of your knowledge in summoning spells. Do you have any books on the subject?"Patchouli sat up a little straighter, couch a few times, and set her book aside before answering Sakuya. "There should be a few books on the subject. Why the

Patchouli sat up a little straighter, couch a few times, and set her book aside before answering Sakuya. "There should be a few books on the subject. Why the sidden interest thought?""Ojou-

"Ojou-sama simply disappeared in front of my eyes. It has to be some sort of summoning from a differernt world, since even Yakumo-san's gaps are affected by my time manipulation."Patchouli's face became much more concerned as Sakuya spoke. "Well, all I can say that you should get some rest. I'll take care of the research. You should consult the shrines tomorrow. The Moriya Shrine Maiden is said to be able to perform miracles, and Yakumo-san tends to send time over by the Hakurei Shrine." With that, she sent Sakuya to try and calm down her heart in mind. She was worried, but she was in Gensokyo, the Eastern Wonderland, she reminded herself. Everything always sorts itself out somehow.

Since SuperNova23 let Rin summon red Saber, which I think is Nero. We're gonna keep Archer and have no Saber summon in this Holy Grail War. Now after doing bits of research on Remilia, let's look at her stats

*Lancer* (Sub-class Caster)
True Name: Remilia Scarlet
Title: The Eternally Scarlet Young Moon or The Scarlet Devil
Gender: Female
Species: Vampire
Strength: A- (C-)
Endurance: B (C)
Agility: A (B)
Mana: A
Luck: EX
Noble Phantasm: B+ [EX]
(-) When being exposed to sunlight, does not affect her Mana or Luck.

*Class Skill*
Magic Resistance – C

*Personal Skills*
Grazing – A
As a participant of Danmaku battles and skills as a Lancer, she has learned to dodge multiple projectiles with little or necessary movement only.

Scarlet Claws – C
Remilia infuses her mana into her fingernails creating a crimson shadow claw, which is stronger than steel and great at close-quarter combat.

Shapeshift – C
As a vampire, she has the natural ability to change her form to that of a bat as she pleases.

Flight – A
As a vampire with wings, she can naturally fly like the rest of the residents of Gensokyo.

Danmaku Firing – A
Remilia already learned to fire Danmaku, which is a continual stream of magical bullets. She can fire them out in patterns as she pleases. At Rank A, she has full access to her catalogue of Spellcards, though using these is a strain on both her and her Master. The limit she can have one active for is 99 seconds, which leaves both her and her Master exhausted.

Regeneration – C- (E-)
With a vampire body, her natural healing far surpasses a human being. She can recover minor wounds during battle, but major wounds will take much longer in combat than outside side of combat. (Expose to daylight, her regeneration barely surpasses human's healing rate, and will take too long to recover any wounds at this rate)

Charisma - C

Charisma Break - B

Noble Phantasm:

Gungnir: The Declaration of the Elder God (Anti-Unit) - A
Gungnir: The Declaration of the Elder God ( 大神宣言グングニル , Ōkami SengenGunguniru ?), which belongs to Odin in Norse mythology, and Brionac: The Five Roaring Stars ( 轟く五星ブリューナク , Todoroku Go SeiBuryūnaku ?), the lance of the Celt god of light and Cú Chulainn's father, Lugh. Due to the constant exposure to Remilia's energies of Fate, Gungnir has gone under a mutation or evloution of some sort to fit the needs of it's owner. With the energy of Fate, it is fated to hit its target without miss.

Mystic Eyes of Fate ManipulationEX
Remilia is able to see the threads of fate and manipulate the threads of anyone she comes in contact with. However, since fates are not absolute, a Servant with enough Luck can challenge a fate imposed upon them. With Remilia's control over her ability, their Rank needs to be A or higher.

Blood Mist: the Embodiment of the Scarlet Devil (Support, B)
Remilia releases a blood-red mist that covers the area. This mist is thick enough to block out the sun, allowing her to go without the sunlight straining her. Like the Blood Fort Andromeda, it can be disable if the starting point of the mist is destroyed, and it takes one full day to dissipate. The mist must have a fixed origin point and must receive an influx of Prana before it can properly work, and takes 48 hours to encompass the skies over Fyuuki City.


I learn that Vampires have the strength nearly par to an Oni so I gave her a rank A- to withstand Berserker's attack. Strength drops 2 ranks, because vampire a weaker in sunlight, and other will drop a single rank. It's false that sunlight kills vampires, just makes them weaker. The next chapter will have more difference with archer being summon. Orginal Credit goes to SuperNova23, ok. See you next month I hope.
