RWOL here with the first of Fate/Stay Night stories in Project Fate. This came about after reading the first chapter of the story Moonlit Fate by Jaenera Targaryen. Interested in Tsukihime, I went to the Type-Moon wikia site and looked up everything about it. Tsukihime got me interested in seeing how it and Fate/Stay night could be combined into a crossover story. So ladies and gents, here is the crossover story that I hope you'll like.

Here is the story known as Fate Blutmond.

Disclaimer: I own neither Fate/Stay night nor do I own Tsukihime. Both are works of Type-Moon so all rights go to them and Kinoko Nasu.

Prologue 1: Return of Akasha's Serpent

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

The Serpent of Akasha.

Ouroboros.

The Infinite Reincarnator.

Those were the titles he was given, the strongest of all the Dead Apostle Ancestors who was ranked as "Extra" – the unofficial Twenty-Eight Rank because his fellow Ancestors considered him to be a heretic who does not uphold the ideals of regular vampires. But he honestly didn't care for he already had what he desired most; "true" immortality beyond that partial immortality of the Vampires. An immortality that allowed him to return no matter how many times he is "killed". He would exist for eternity, as he desired in his early days.

For he was Michael Roa Valdamjong and he was eternal.

Before becoming the dreaded Serpent of Akasha, he was originally a priest of the Church who quickly rose to the top by utilizing all of his father's inheritance and founded the Church's Burial Agency alongside the first Narbareck. With nothing left of his resources, Roa decided to leave the Church, giving the Agency to Narbareck and betrayed the Church to the Mage's Association. He wished to realize an immortality different from that of vampires, who while biologically immortal still suffered from the gradual degradation of the soul. But, in trying to overcome his limits as a mere human, he reluctantly became a vampire in order to continue his research. When considering a way to become a vampire, he extensively studied both the True Ancestors, the first generation of vampires known as Dead Apostles and the later generations of vampires created by the First Generation and how they turn people into vampires.

He discovered that when a True Ancestor (or another Vampire) creates a new vampire, the power of the soon-to-be vampire in question raises in proportion to the True Ancestor's (or Vampire's) strength. He also theorized that if one's magical potential was great enough, they could go further in terms of power by using magecraft to enhance their power to greater heights. Therefore to become the strongest Dead Apostle, he had to seek out the strongest True Ancestor in existence… Arcueid Brunestud – the White Princess and Heir to Type-Moon. With Arcueid's literal transcendent might combined with his own exceptional magical potential, Roa would be a vampire the likes never seen. Maybe more powerful than the legendary Dark Six.

But when he first laid eyes upon Arcueid, unknown to Roa his heart was snatched away by the True Ancestor. Her beauty was utterly peerless, her grace unmatched, her power unrivaled. She was perfect… too perfect in his imperfect eyes.

Michael Roa Valdamjong had fallen in love with Arcueid Brunestud.

And this was his folly, even if unknowingly. Ever since he was born, he had no interest in anything in particular, feeling more mechanical than human. His first feelings were those of pity rather than anger or despair. He simply thought everything around him was pitiful, and he himself was the most pitiful of all. He could not comprehend these "emotions" he felt for Arcueid because he didn't normally feel anything. He never noticed that he genuinely fell in love with her, but instead started hating her after it caused him to lose his innocence and turn away from his research.

When Arcueid became weak to her vampiric impulse for the first time in her castle, he tricked her into drinking his blood by creeping up behind her, trying to seduce her with sweet words and asked "Are you in pain?" She sucked his blood right there, and he 'died' immediately. After being brought back to life, he became distant from her, not once speaking after that point, and only met later to finish everything. He became a powerful Vampire upon his 'revival' and quickly made a name for himself in the vampire community. He did so by taking the forces of the Dead Apostle Ancestors that had then been sealed by the Church, he quickly rose in power amongst the twenty-seven. He earned himself the scorn of the other Dead Apostles Ancestors as he built up power, and eventually Altrouge Brunestud was left in charge of punishing him. He proved too vastly powerful in battle, reflecting the magnitude of the power gained from Arcueid at her peak and his exceptional quality as a magus, and defeated Altrouge without killing her. The rest of the Ancestors decided to reject him and ignore his existence after that point, and, years later, he was eventually destroyed by Arcueid who had joined forces with the Church. Over the next seven hundred years, he reincarnated fifteen times, and he was endlessly killed by Arcueid each time.

Roa's seventeenth incarnation, Elesia, later known as Ciel, was born in 1976 to a baker's family in a remote village in France one hundred years after his sixteenth incarnation died. The sixteenth was destroyed by Arcueid before he had a chance to find a family bloodline with both wealth and power. He could only fulfill the requirement that his next incarnation would have physical potential, so he was born into a normal family without any social standing. In exchange, Elesia's body instead had extremely high magical potential, which is the closest in power to his original body in all of his incarnations. He began manifesting on her sixteenth birthday, and greatly enjoyed the amount of power the body gave him. Even though he would have to take a long period of time to take over the town without status, he was fine with waiting until later to obtain social standing. He committed various atrocities to the citizens as he used his new powers to slowly take over the town. After the town was completely under his control, he was inevitably hunted down by Arcueid, who managed to find him after two days of searching.

He was killed but like before he would return once more. While inhabiting Elesia's body he sought out a proper vessel for his next incarnation and knew he needed to think outside the box when it came to finding a suitable host. Roa had mainly focused his searches within Europe since nearly all of the magi Houses were congregated in the European continent due to Clock Tower. So he decided to look outside of the Euro nations and found the island nation of Japan. There he found several families that were either magi or demon-blooded House.

Even more advantageous was due to how Orientals are treated by Western magi, nearly all of the Japanese magi Houses were non-affiliated with Clock Tower which would give him a certain level of protection against Arcuied and the Church as they would never think of looking in Japan for him. Now he just had to choose the family which had the proper level of wealth and power. And he found it.

After all, who would ever think that Roa would use a family being backed by the infamous Old Man of the Jewels himself.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

You're doing well. You've made some startling advancements with your Jewelcraft these past few months.

"Hmm." The young child hummed and nodded absently to the voice in her head. Young Tohsaka Rin smiled as she looked over her current project; her very own Mystic Code the Jewel Staff. It was modeled after her father's version, designed to help channel her mysteries without an aria, actualizing her spells in a manner similar to Homunculi who simply needed the knowledge of the spell they want to use and in conjunction with their imagination. Though Rin's staff differed from Tokiomi's in that hers has more than just rubies in it. Tokiomi had an elemental affinity towards fire so his code allowed him to summon various Flame magecraft spells.

Rin on the other hand was an Average One, a magus possessing all five of the Great Elements: Fire, Wind, Earth, Water and Ether. As such Rin needed her Mystic Code to allow her to actualize all five elements in short order like her father does his flames. Proving her prodigal genius, Rin created a jewel matrix system with different jewels as foculi for her elemental magecraft: a diamond in the middle of the of the matrix functioned as both a container for ether and an absorber/converter of mana; absorbing mana from the Greater Source and converting it into her Odic signature (the Lesser Source).

Around the diamond in a pentagon formation were a: ruby, emerald, sphene, sapphire and another diamond. Rubies (and its variants Rubelite and Spinel) were naturally aligned to the fire element. Emeralds were naturally aligned to the wind element. Sphenes were naturally aligned to the earth element. Sapphires were naturally aligned to the water element. Diamonds, the most unique of the precious gems, were neutral allowing them to be naturally aligned to ether, the four classical elements and the non-standard elements such as Light, Darkness, Lightning and Thunder, Wood and Metal.

The staff's body was composed of alchemically treated Lignum Vitae wood for strength and stability and also for close-combat situations she might be forced into.

You are truly a genius my other half. Only seven years old and you have already created your own Mystic Code. Rin's magus-self said with pride. Rin puffed her chest in pride at knowing she once again proved why she is the Tohsaka heiress and it was partly thanks to the voice that she identified as her magus-self. It was during her initial studies that the voice first spoke her. At first she was afraid until the voice explained it was a part of her; the Magus she would become in the future if she kept to this path. Rin had quickly accepted what the voice said as said voice proved that it was indeed her Magus-self since it was always helping her; offering advice when she needed it, warning her if she was about to make a mistake, breaking down her magical theories and pointing her in the right direction, and whatever else she needed in order to advance her craft.

"Now then, time to test you out my little darling." Rin cooed to her Mystic Code before turning to a sectioned off area in the workshop her father gifted her when he began her magecraft training. The section had a mannequin placed there so she could test out her spells on a target in a controlled environment. Channeling her Od into the staff, while also using Structural Analysis on it to see if her Od was moving correctly, seeing that it was absorbed by the diamond, combined with mana the diamond took in and converted said mana into her Odic signature and then evenly distributed it into the other jewels. As they lite up one by one, glowing with her power Rin smiled as she saw her matrix system was working properly.

Focusing her Od into the ruby and causing it to glow brighter, Rin launched one of her father's spell with the chant of "Intensive Einäscherung!" at the mannequin and watched in glee as the spell didn't break down and the flamethrower devastated the mannequin.

Getting her excitement under control, Rin went over to her desk where her note book was and jotted down the effects of her experiment as she was instructed to by her father. She recorded how the diamond in the matrix absorbed the mana in the air, converted it to her Odic signature and distributed it among the other jewels in the matrix. She recorded how her Od was channeled through the staff and into the ruby where it successfully triggered the prana inside the recently stored and converted mana. And she recorded how her spell was successfully actualized.

Rin repeated this several more times for each element: wind, earth, and water. Despite being confident in her Mystic Code, she decided to err on the side of caution and continue testing her code to truly make sure it worked perfectly. Better to find any and all surprises while testing it here in her workshop than find a surprise in the middle of a violent confrontation and get killed.

A wise idea my other self. A few more weeks of testing then we can see how our version of the Jewel Staff compares to our father's.

"Just another step on my journey of becoming the Tohsaka Head." Rin said already envisioning herself leading the Tohsaka to glory. Shaking herself out of her fantasy, Rin noticed the time and decided to call it a night. Tidying up her workshop and placing her Mystic Code onto her experiment table. Locking up and activing her workshop's defenses, Tohsaka Rin headed into her home Tohsaka Manor, headed to her room, did her nighty rituals before heading to bed.

Deep within Rin's soul, Michael Roa Valdamjong (taking the form of a towering serpent with four appendages similar to arms with four clawed fingers along with a cobra-like hood and a rattlesnake's tail, teeth taking on the form of a poisonous snake's fangs, resembling those of a cobra and his massive body being colored purple, a black colored underbelly, vampiric red eyes with unusual pupils in the shape of the infinity symbol) smiled deviously as his choice of choosing House Tohsaka was more beneficial than he thought.

The first benefit was that he had awakened earlier than expected, which meant he had more time to build and consolidate his power before his inevitable confrontation with his dear White Princess and considering how he chosen the Japanese magi-family House Tohsaka, it would probably be years (possibly decades) before Arcuied finally realized he was no longer in Europe and go on a wild goose chase trying to find him. As long as he played his cards right and moved smartly, he could regain enough of his power to rival his original body and finally gain an upper hand against Arcuied.

The second benefit was his current host having great potential; forty inborn natural magic circuits that were A-Rank as well as an above-average sized Od pool for such a youngling. Combined with her natural prodigious genius and her Average One status, this current reincarnation rivaled the potential of his previous incarnation. As long as he kept guiding her down the right path and supplement the Tohsaka's teachings with his own, then Rin would develop far faster than even she and her father would expect.

"Soon…" Roa began with an oily smile on his serpentine face. "Soon my dear Arcueid we'll settle this once and for all and this time, I'll win!" he chuckled vindictively at the thought of seeing Arcueid finally dead at his feet after seventeen constant defeats by her hand. Roa continued to chuckle as he receded into the recesses of Rin's mind, patiently waiting for his eighteenth second coming.

XXXXXXXXXXXXXXXXXXXXXXXXXXX

"I'm so proud of you my daughter." Tohsaka Tokiomi said after looking over his eldest daughter's version of his Jewel Staff. Tokiomi was a fairly tall man in his late twenties-to-early thirties with intense aqua eyes, black hair and a goatee. He wore an immaculate red suit with a navy blue ribbon tie and polished brown dress shoes. Three weeks had passed since Rin had created her own Jewel Staff and after constant tests and double-checks to make sure her staff was working in the correct manner, she had presented it to her father who was honestly shocked she was able to create her version of his Mystic Code.

Though she could have waited after family breakfast to present her project, but since she is still a child he wouldn't fault her for being excited about completing said project.

Anyway, Tokiomi had gone to his workshop (the first basement level of the Tohsaka Mansion) to get his Jewel Staff before asking his daughter to take him to her workshop (the second basement level) and explain how she was able to create her own version of the Jewel Staff. After looking over her notes, which were properly detailed and well-written, along with listening to her explanation, Tokiomi was left utterly dumbfounded at the genius his eldest daughter possessed. After all it's not every day a seven year old magus child successfully creates her version of her father's Mystic Code. Truly he had been blessed to have such a gifted daughter and he knew beyond a shadow of a doubt the Tohsaka was in good hands with Rin as next leader. He moved forward and ruffled his daughter's hair, giving her his congratulations for her creation.

"I'm so proud of you my daughter." Tokiomi said, his aqua eyes shining with pride and smiling widely at his beaming daughter's face. "If you continue at this pace, you'll replace me as Tohsaka Head before you're a teenager." He joked getting his daughter to laugh. As the two continued to have their moment, they were unaware of being watched from the partially open workshop door. Tohsaka Sakura stared at the happy father-daughter scene with sadness, anger and jealously.

She hated it.

She hated it.

She hated being the second-born, the spare in case the first born fails or dies.

She hated being overlooked for Rin.

She hated her father for focusing so much time on Rin and ignoring her. She hated her father for being a father to Rin but a stranger to her.

She hated her mother for just accepting the situation, not even trying to convince her husband to spend time with his second daughter. She hated her mother for being as weak-willed as to not question her husband and just accepting his words like they were law.

She hated her sister Rin for being the first born and thus the next leader of House Tohsaka.

So Sakura decided to take the initiative and teach herself since her father didn't state she couldn't teach herself magecraft. She would make her father acknowledge her, make him see her as something more than the spare heiress, make him smile at her like he does as Rin.

XXXXXXXXXXXXXXXXXXXXXXXXXXX

"That little bitch!" Rin screamed in anger as she slammed the door of her workshop close, causing the walls to rattle a little from the impact. Rin's anger was towards her younger sister Sakura who had dared trample on tradition by teaching herself magecraft. There was only supposed to one magus per each family's generation so as to not cause and even encourage competition. While competition could be seen as helpful, in the world of magi it was detrimental as considering how cutthroat magi are, any and every means will be employed to come out as the victor and this sows chaos and invites ruin to magi families.

The only known family that didn't suffer from such a fate was House Edelfelt (rivals of House Tohsaka due to both being Jewelcraft specialists and due to them being distant relatives thanks to the younger Edelfelt sister marrying into House Tohsaka after the Third Holy Grail War) thanks in part to their Sorcery Trait known as Ore Scales which allowed them to have two successors to their house with twin crests.

House Tohsaka didn't have such an advantage and Rin feared her place as Tohsaka heiress was in jeopardy with Sakura trying to become a magus herself. Why would her father allow Sakura to learn? Even with such a flimsy loophole, Sakura should have been punished for going beyond her station.

So why in the Root of everything did her father allow Sakura to continue her foolish actions?

"Sakura…" Tokiomi began looking at his youngest child. He had taken Sakura with himself, Rin and his apprentice/ally Kotomine Kirei to his workshop as since Rin and Kirei had lessons today, and he could kill two birds with one stone. Sakura fidgeted uncomfortably, even more so after Tokiomi raised a grimoire and a neatly-folded set of notes with it. "You know what these are, are they not?" he asked.

Sakura mustered her courage and stared defiantly at her father. "I'm not sorry for what I've done."

"Oh..." Tokiomi said wondering where this was coming from and actually liking it.

"I'm not sorry for I've done nothing wrong." Sakura said getting Tokiomi to raise an eyebrow while Rin was shocked at the audacity of her younger sister. "While you did say that I cannot be taught, you didn't say that I could not self-teach myself to become a magus on my own." Sakura said revealing the loophole she was taking advantage of. Rin glared at her sister but before she could say anything, she was stopped short by her father's laughter.

"Hahahahaha!" Tokiomi laughed before getting himself under control. "While your persistence to learn the Art, as rebellious as it is, is in its own way commendable and even admirable. With that said…" Tokiomi paused and glanced at his apprentice. "She could not have obtained this material…" he continued. "…without your assistance, Kirei-kun."

Kirei closed his eyes before answering his master in the mystical arts. "As Miss Sakura said, you didn't state she could not study and become a magus on her own. I merely made sure she started off small before trying to learn the more advanced crafts."

"And you made the right decision Kirei-kun." Tokiomi said with nod towards his student. "As for you Sakura, I'm proud of you." he said turning back to his youngest daughter. "You reason like a magus, and have the spirit to be one. As you say, you will not be taught. That is what tradition demands. But there is no reason for you not to study on your own, and I was wrong not to let you do so." Tokiomi said handing Sakura's notes back to her which she accepted with some hesitance. After all she was expecting to be punished, not given the green light to continue her studies.

"Do your best, Sakura." Tokiomi said.

"Yes! I will!"

"Damn you father for letting Sakura get away with this injustice!" Rin raged firing a Gandr shot at the wall.

Calm down and fear not my other half. Rin's Magus-self spoke up and catching Rin's attention. Even with our sister learning magecraft on her own, our position as heiress is not in danger. Why? Because Sakura is alone for she has no one to truly teach her. She can't go to our father or us for help since due to the little loophole she found and exploited, she has to self-teach herself. Without true guidance our sister can't accomplish much on her own so she will fail.

"Still…" Rin said uneasily.

Think of it like this; a test from our father.

"A test?"

Yes a test. You are a prodigy the likes House Tohsaka has never seen yet you can only go so far on your own. That is where our dear sister comes in, for she will prepare you for the day you gain a proper rival. At the rate you're going, you'll easily get into Clock Tower and that is where your greatest test will happen. You will not only have to overcome the racism that western magi give to Oriental ones, but also prove why the infamous Wizard Marshall Zelretch chose House Tohsaka as a possible successor to his craft. During this trying time, you will find that one person who will be your principal rival; the one who will force you to go even further in your craft, who will push you to constantly do your best to surpass them, and who will constantly compete with you until either you or they admit defeat and that the other is superior. That is what our father wants; to prepare you for that time.

Once Rin fully calmed down, she thought over her other self's words and after several moments nodded her head in acceptance of them. It was only a matter of time before she got into Clock Tower and from the few stories her father told her about his times there it wouldn't be a walk in the park. Constantly looked down upon for being Oriental, constant attempts at sabotage, constantly watching his back for attacks and betrayals… Tokiomi had to fight tooth and nail for everything he has now. And Rin would go through the exact same thing once she gets to Clock Tower.

So knowing this, Tokiomi was going to prepare Rin by giving her a taste of what a rivalry would entail by using his other daughter to do so. He was not endangering Rin's position but helping her solidify it; by proving herself ready for one of the major rigors of Clock Tower by defeating Sakura in a practice rivalry.

Rin couldn't help the feral grin that appeared on her face as she thought about her future. By crushing Sakura, she'll establish herself as worthy of being House Tohsaka's heiress and later leader. With Sakura gone and Rin in charge, she'll reform House Tohsaka in her image and take it to heights that not even her ancestor Tohsaka Nagato could have thought possible. She would rise to the top of the Magi food by becoming an Archmagus, hell even a Wizard Marshall was a possibility for her. She would leave behind a legacy her descendants would honor for generations to come.

"Well then little Sakura, you better bring your A-game because only your best will make my victory all the sweeter when I end you with my bare hands." Rin said with a dark smile.

XXXXXXXXXXXXXXXXXXXXXXXXXXX

"And so after careful deliberation I've decided to hand you, Rin, over to the Matou."

Rin couldn't believe what she just heard. She could not accept that what her father had just said to be reality. She tried to reject it but the words her father spoke played through her mind like they were stuck on a repeating loop. Three months had passed since Sakura was allowed to learn magecraft on her own. Rin had taken it upon herself to show her sister the reality of the situation she caused for the two of them only a few days after the decision.

"Nee-san?" Sakura questioned looking up from her notebook when she sensed a presence near her. Said presence was her older sister. They were in the third basement level of the Tohsaka Mansion that was designated as the magical library for House Tohsaka.

"I'm not your 'nee-san'." Rin said coldly getting Sakura to flinch back and widen her eyes in shock at that declaration. Rin gave Sakura a feral smile when saw her reaction. "You and I are no longer sisters Sakura. The moment Otou-san allowed you to learn magic, you became my enemy as I yours."

"What are you talking about nee-san?" Sakura asked pleadingly. Why would Rin say they're no longer family? That they were enemies? This wasn't making sense!

Rin moved, grabbing Sakura by her shirt and pulling her close until their noses were nearly touching. Rin couldn't help but enjoy the fear and shock in Sakura's eyes, licking her lips before she spoke. "Do you think that Otou-san would just let you learn magic like that? Silly little Sakura, Otou-san only let you do that not because you out smarted him but because he finally had a use for a spare like you. You Sakura will be nothing more than a stepping stone on my path of greatness… a mere footnote in House Tohsaka's history when my descendants read about my rise to power." Rin said enjoying the pain Sakura was in as the tears fell. Letting Sakura go and watching her fall flat on her ass, Rin turned on her heel and left the sobbing girl.

Three months of hard work; her blood, sweat and tears in slaving away to prove herself worthy of being a Tohsaka and her father does this! Why?

"Why would you do this Otou-san?" Rin shouted at her father.

Tokiomi steepled his fingers before answering. "A few weeks ago, House Tohsaka's old ally House Matou and its head Matou Zouken approached me asking for aid. He wishes to adopt one of you in order to save their dying bloodline…"

"Then why not just give him Sakura since as the second-born it's her duty to House Tohsaka." Rin counter argued. Tohsaka Aoi lowered her head knowing that her eldest was right as it was Sakura's duty to House Tohsaka. A second-born within a magi family had three specific duties: 1) being a spare should the first-born prove lacking as a magus or he/she is slain before taking their place as the next head of their House; 2) to help breed a specific trait (i.e. unique Sorcery Traits or rare elements) and the children from the breeding program that successfully gained the desired trait will then be introduced into the main bloodline via marriage; and 3) to cement alliances with other magi Houses whether by marrying them off to the heir/heiress of another House or acting as a political hostage. Sakura merely looked betrayed and even more emotionally hurt that Rin would willingly want her to be given away to a bunch of strangers even if they are old allies of House Tohsaka. It was bad enough she claimed they were no longer sisters and only enemies. "At least this way she'll get what she wants in learning magecraft."

Tokiomi nodded. "You are correct my daughter on all accounts but there is more to this decision than just that." Tokiomi sighed before continuing. "You and Sakura are unique because of your immense innate potential but also because of the exceedingly rare sorcery traits you two possess. You Rin possess all five elements while Sakura, though lacking all five, possesses Imaginary Numbers which is both her element and Sorcery Trait, meaning she can pass it along to her children and so forth. Without the backing of a magical family, the daughter that I didn't train would be in danger. So this allows me to save said daughter while still giving her the chance to fulfill her innate potential to become a powerful mage." Tokiomi explained before looking his eldest daughter in the eyes.

"And so after careful deliberation I've decided to hand you, Rin, over to the Matou." Tokiomi said shocking everyone. "Simply put, as an Average One you'll have an easier time learning the Matou craft than Sakura because she lacks the needed water element. House Tohsaka will have a positive gain with Sakura as heiress due to her Imaginary Numbers while you Rin will be neutral gain for us but a positive one for House Matou long-term." Tokiomi said weathering the dark glare that Rin gave him before she stormed out the room.

Unbeknownst to the rest of House Tohsaka, Roa had heard everything was displeased at what was happening.

Looks like I'll have to make my move sooner than I thought.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Rin stood before her former father, mother and sister with her luggage being taken away by one of the ten House Matou henchmen to the limo waiting outside the Tohsaka Mansion gate with Zouken waiting for his newly gained granddaughter inside of said limo. One week had passed since Tokiomi had decided to give Rin away to the Matou. Aoi had tried to spend her final week with Rin but the former Tohsaka heiress refused to let Aoi anywhere near her. Tokiomi had graciously allowed her to take her research and notes with her so she could start right back up where she left off. Sakura had avoided her sister as she always did since the day Rin denounced her as her sister.

Worry not my other half, I'll take care of this problem… if you'll let me.

How? Rin questioned as she ignored her former mother's tearful goodbyes and her former father's attempts of encouragement.

Trust me and I'll show our former family the mistake that they're making.

Do it! Make them pay for this! Rin said vengefully.

Fire ripped through her body at those words, her blood boiling as Rin collapsing to her knees to everyone's concern as she began breathing hard. It was… terrible. Magic was painful, like hot metal being stabbed into you, but this… it was nothing like this. It was like each and every last one of her nerves was being stabbed with white-hot needles, her bones felt like they were being crushed by her muscles as they tightened and contorted against her will…

What are you doing? What's happening to me?! She screamed in her mind. There was no answer, and she barely registered falling to the ground screaming and thrashing, her former mother rushing over and pushing the Matou henchmen away as she tried to calm her down. Through a haze of tears she saw her former mother's terrified face and… and… and…

…thirsty…

She heard and felt blood pumping with every beat of her former mother's heart.

…thirsty…

She could see the faint outline of blood vessels in her former mother's neck, filled with rich, warm, healthy blood.

…thirsty…

She felt warmth with every touch of her former mother's hands as she began to relax, catatonically staring up at her former mother's face. Warm… warm… alive…

…thirsty… I'm so thirsty…

She could see and hear her mother trying to wake her up, a crimson haze blanketing her sight as hunger like nothing she'd felt before filled her. She dimly registered the burning in her body as her fingers contorted into claws, and her canines grew into fangs.

…thirsty… I'm so thirsty… I'M THIRSTY!

Then hell was unleashed. Aoi could not react fast enough as her former daughter latched on her and bit her deeply in the neck. Aoi screamed in pain as Rin drained her of her blood, the scream getting her husband to shake himself out of his stupor and move to help along with the Matou henchmen. Rin reacted to this, tearing out a chunk of Aoi's neck before disappearing in a blur of movement and blood flew as three of the nine Matou henchmen were dead on the ground, torn to pieces and their blood staining the walk way. Tokiomi looked up from his dying wife to see the burning red eyes of his daughter and his blood ran cold.

No. It should be impossible. There was no way for this to happen.

And yet it did and it was staring him down right now.

Somehow… Rin had become a vampire.

Rin looked at the heart in her hands and smiled before bringing it to her mouth and taking a bite out of it, moaning in ecstasy at the flavor she was experiencing. She then crushed it, sending the remaining blood into her mouth before throwing it away. She moved and ripped out the other hearts of her victims and repeated the action, enjoying the taste of rich blood. Her meal was interrupted when one of the Matou henchmen rushed her in blind fury but the girl merely smirked before vanishing with blinding speed and reappearing in front of him, sending a kick to his torso that ruptured his stomach and sent him flying towards the still shocked Sakura. With another burst of speed, Rin vanished and Sakura screamed as the flying Matou henchman exploded into blood and offal, drenching her in said materials.

Rin devoured the heart from the her fourth victim, moaning as the rich fluid known as blood filled her mouth and slid down her throat, not wasting the precious material by licking the blood around her mouth and coating her fingers. And then everything exploded into motion once more, with Rin releasing dark cackles as she charged towards the remaining House Matou henchmen. Said henchmen didn't stand a chance against the newly born vampire as she tore into them; draining their blood while she tore them to pieces.

Kirei finally made his move when he came out of the Tohsaka Mansion to investigate all the screaming he heard. Seeing the situation at hand, the Church Executor rushed towards Rin, his Black Keys flashing in his hands. Grinning maniacally, Rin charged inside of his guard with surprising speed and landing a kick on his stomach. Even with her newfound strength it was barely enough to stagger Kirei… but the shock of lightning that came with it forced him instinctively back. As he fell back, Tokiomi got in on the action by throwing a kick at his daughter's head. She dodged and attacked, fluidly swiping at him with her claws.

Tokiomi dodged the first two swipes, and caught the third on his arms. Reinforced cloth tore like wet paper, Tokiomi falling back and diving low as Rin launched another attack. Stepping behind her he threw another kick at her. She caught it on her arms but it was enough to send her flying a good distance. Rin landed on her feet, snarling as swarms of Matou familiars surrounded her. Claws flashed as she cut hundreds of them down in one blindingly-fast motion, and then she was choking on her blood as Kirei charged in, landing a crushing blow on her chest. The sound of his daughter's ribcage caving in was like a dagger in Tokiomi's heart, and he looked away, his face twisted in agony as he felt hot tears out of his eyes.

Rin flew back, landing on the opposite of the street and lying motionless.

Kirei relaxed and turned towards Tokiomi and seeing the Matou Head Zouken approaching slowly, the latter freezing as Tokiomi turned icily at him.

"Matou-san…" Tokiomi said icily and getting Zouken to sigh, disappointment showing on his face. With Tohsaka Rin now dead the agreement was now broken, which meant Zouken wouldn't get what he wanted. He had originally wanted Sakura since her Imaginary Numbers were suited for his plans, as he had no real intention to train his future 'granddaughter', but instead got Rin due to her Average One status which would allow her to 'learn' the water-element based Matou magecraft. While he did ambiguously state he wanted to adopt one of the Tohsaka sisters, he was hoping that Tokiomi would give him his second born but it was clear that he underestimated Tokiomi since he gave up Rin in Sakura's place.

The old man opened his mouth, hoping to find some way of salvaging the situation but he along with Tokiomi and Kirei turned as a scream rang out. "Sakura…!" Tokiomi shouted as he saw his youngest daughter being assailed by… Aoi herself?! Tokiomi rushed towards the two with Kirei making to follow, but he barely took two steps before the sound of tearing flesh drew him back. He turned just in time to see Rin spitting out blackish ichor.

"You taste disgusting!" she spat at Zouken's twitching corpse, her claws dripping with the old man's fluids. Her next action surprised Kirei when she did the chant for the Baptismal Sacrament at high-speeds (She can do High-speed Incantation?). Zouken could only scream in utter agony as his decaying and rotten soul was purified. In mere seconds, Makiri Zouken, formerly Makiri Zolgen, was no more. The ancient, five hundred year old magus killed by a mere child turned vampire. Smiling at her handiwork, Rin turned back to Kirei and smiled, her fangs showing as she flexed her claws. "You won't kill me that easily, priest!"

Kirei fell into his stance, Black Keys flashing into existence once more. Rin grinned, and then lunged at him with claws flashing with blood and sunlight. Kirei dodged at the last moment, an elbow coming down with a sound of breaking bone as he smashed Rin into the ground. Metal flashed and the vampire screamed and shouted in frustration as Kirei pinned her bodily to the ground with his Black Keys. He considered using the Baptismal Sacrament right then and there, but he hesitated and looked towards his master as he was forced to kill the Dead Aoi in order to save Sakura. His master would probably want to investigate this development, impossible as it was.

Or was it?

Before he could contemplate further, he was slammed harshly by an unknown force, bouncing along the pathway before finally stopping himself. Groaning slightly, he kipped up and saw who had attack him. She was of average height with the classic pale skin and red slitted eyes of Vampirekind. She has short, messy black hair and wore a military-styled outfit: a black jacket with gold-colored edges that is very open, revealing her chest, and has a dark brown belt with the Infinity Cross on the buckle. A black mini skirt with white tights underneath and a pair of black thigh-high heeled boots covered her lower half. The outfit is completed by a pair of white gloves and white collar-styled choker. Kirei saw that the unknown woman had removed the Black Keys from Rin's body and was helping her stand.

"Ah, thank my dear Cradula." Rin said looking at the woman with gratitude.

"My will is to only serve you milord." The woman, Cradula, said bowing her head in a servile manner.

"As you should. Now let's leave this place… also grab the girl's luggage as it contains her research." Rin said as the woman nodded and then snapped her fingers. Kirei found himself surrounded by six figures that his senses told him were vampires. They all wore vampiric versions of the Church Executor uniforms, with the Infinity Cross denoting them as cultists. Kirei's lips twitch upward as he felt like laughing since seeing these vampires make a mockery of the Church was funny to him. The vampires threw themselves at Kirei who defended himself against the onslaught which became more challenging due to the fact that they were clearly well trained in the art of combat.

As this went on, Rin and Cradula made it to the Matou limo, a no-stretch Cadillac Escalade CEO Executive - Bentley Edition, which they promptly hijacked after Cradula lit the other two regular Escalades on fire. As they rapidly sped off, Roa contemplated his course of action. He needed to lay low and continue to build power for his inevitable encounter with Arcueid but also keep House Tohsaka off his back in their attempts to regain Rin. But where could hide from now on until he was ready.

"Where are we headed Cradula?" Roa, currently using Rin's body, questioned his slave.

"Milord," Cradula spoke up turning her head slightly to look at her lord's current incarnation. "We're headed to the local temple which we – the Infinite Serpent – have brought under our control. The residents are under mental compulsions to carry out their daily duties while ignoring us." Cradula started. "During our setting up, we came across a large underground cavern seemingly set up for some kind of formalcraft ritual. There is even a workshop-like area already set up so that is taken care of for you." She said to her lord.

"Hm. Strange. I'll check it out once we get there. But for now I want decoys deployed to send House Tohsaka on a wild goose chase. I'll hide in plain sight while tricking them into believing that I've already fled Fuyuki and Japan as a whole." Roa said with a smirk.

"Of course milord. There is one more thing I need to tell you milord." Cradula spoke softly.

"Yes."

"We may have discovered a way to recreate your original DAA (Dead Apostle Ancestor) body."

The widening of Roa's eyes was all Cradula needed to start explaining this possibility to regain his former glory.

They huddled together in the Tohsaka Mansion living room, holding tight to each other as the events earlier today relentlessly replayed through their minds. "Okaa-san… onee-san…" Sakura whispered still covered in blood as her tears refused to cease even after all this time as she clung desperately to her father. Tokiomi didn't say anything, also still crying in silence as he held his only remaining daughter. Everything he had held dear, everything he had hoped for…

…it was all gone.

Why?

Why did this happen?

How could this have happened?

The answer didn't come to him but he knew of a way to possibly fix this and regain what he lost today.

The Holy Grail.

The prize of the vaunted Holy Grail War, whose fourth iteration would happen with the next six months.

Yes.

The Holy Grail was the key to solving this clusterfuck and with the Heroic Spirit he chose for his Servant House Tohsaka would win this war.

(Mifune City: Garan no Dou)

Garan no Dou (伽藍の堂, Hollow Shrine) is a contract-based agency run by "Boss Lady Mahoyo" where all kinds of jobs are taken, ranging from the mundane to the supernatural. Boss Lady Mahoyo was a beautiful woman standing five-feet and four inches tall with bright reddish hair in a short ponytail and matching colored eyes. She wore a simple button-up dress shirt and calf-length, slim-fit black slacks with the outfit being finished by low-heeled shoes.

Her 'office' (in reality her workshop) was the largest room in the entire building (as she made the entire top floor her workshop) was more of a mundane art studio that also doubled as an 'office'. There were several puppets leaning against the walls where some were either complete or incomplete due to missing either their arms or legs or both or were 'skeletons', numerous puppet parts scattered about on the floor along with tools to help with puppetry construction. Blue prints concerning new and old puppet designs were also scattered about along with several tomes on alchemy, doll-making, golemancy, mystic eyes, runecraft, puppetry and wind magecraft. To add to the mess there were several take-out food containers from Mifune City's best restaurants.

In the lower right hand corner of the room, was a large Bestar Pro-Linea U-Shaped Desk with Hutch. Next to her desk, about ten-feet away, was a vertical Murphy bed designed to look like a filing cabinet. The Boss Lady sat behind her desk, ignoring the usual mess of her workshop/office, focusing on her latest puppet design when her secretary buzzed in on the intercom.

"Yes Azaka." Boss Lady Mahoyo said answering the call.

"We have a client requesting a meeting with you."

"Send them in."

Placing her current work to the side, Boss Lady Mahoyo looked towards her office door as it opened letting her next client in. She wore a simple dress suit and skirt combo with low-heeled shoes that hugged her fairly curvy figure. She was of average height with pale skin and red slitted eyes, and short messy black hair. The woman carried a suitcase in her right hand. The woman walked confidently towards Boss Lady Mahoyo, ignoring the mess on the floor before taking a seat.

"What can I and Garan no Dou do for you today Miss…" Mahoyo started off right to business.

"Cradula. No surname." Cradula spoke as she placed her suitcase on Mahoyo's desk. "And what you can do for me, no my master, Immortal Puppet Master, is to create the greatest work of puppetry you will ever create." Cradula said coolly.

"So… it's one of those jobs." Boss Lady Mahoyo, or actually Aozaki Touko the Sealing Designated Immortal Puppet Master, spoke getting serious. "Your master wants me make him a new body eh?" Touko asked.

"Yes. And money is no issue." Cradula said unlocking the suitcase and turning it around for Touko to see. Touko's eyes bulged open in shock as her glasses slipped off her face. "My master is prepared to pay you 73311000000.00 yen, or $700,000,000 US dollars, in two payments. The first half, 36639925000.00 yen or $350,000,000 US dollars, now should you accept his request and the rest when you complete said request." Cradula said to the silent Touko. It took several moments for Touko to regain her composure from the shock of the amount of money being offered to her for this request.

"Let's talk terms." Touko purred as Cradula smiled victoriously.

And cut! Here is the first chapter of Fate Blutmond. For those who don't know, Blutmond is German for "Blood Moon", a rare astrological event where the moon appears as a blood-red color. It is a fitting name as in some legends, vampires are connected to the blood moon where their powers are enhanced to the maximum degree. As I said before, I was inspired to do this story thanks to Moonlit Fate by Jaenera Targaryen, but this will not be like Moonlit Fate. The first three chapters will be unique, stand-alone prologue chapters that will introduce the main characters of Blutmond: Shirou, Roa, Ciel and Arcueid. Ciel and Arcueid will share the third and final prologue chapter with the fourth chapter being the actual start of Blutmond.

Prologue 1, as you've read, focuses on Roa himself. The first part of this prologue is a brief and quick detail of Roa's life both before and after his rise as a DAA. Which I took directly from his Typemoon wikia page, which frees up my time to get this prologue finished. Then we get to his 18th reincarnation Rin and seeing how Roa is gently guiding her to true potential because the stronger she becomes before he fully takes over, the stronger he'll be when he fully does. We see Rin proving her genius by creating her own version of her father's Mystic Code the Jewel Staff and I hope my explanation was good enough.

As for Rin's character, I'm taking some cues from her prototype character that was originally meant for Fate/Stay Night but was changed and this version would later become Misaya Reiroukan in Fate/Prototype. This Rin is more like her father in her mentality towards being a Magus; being calculative, callous and cruel towards those who get in her way. So you're going to see a more Magus-minded Rin in this story.

We get to see a little bit of Sakura and her feelings towards her family; the anger and resentment. After all anyone in Sakura's place would feel such a way receiving the same treatment. Rin is the first-born and heiress so it is not surprising that Tokiomi will focus mainly on her while neglecting Sakura. Sakura's feelings towards her mother are, to a degree, justifiable as well but Sakura doesn't know that Aoi already knew what was going to happen when she married Tokiomi. Aoi knew what it would mean to marry a magus and thus accepted her role as the 'wife of a magus' since in canon Aoi didn't openly oppose Tokiomi's decision to give Sakura to the Matou. So with everything happening to her, it is no surprise that Sakura would attempt to gain her father's love by trying to become a magus herself.

As for the whole 'House Tohsaka' thing, that is a real life thing that nobles do. When they introduce themselves they say "I am such and such from House Such and such." And seeing how most, if not all of the magi families in the Nasuverse are nobles (with most having ancient lineages), it is something that they would do.

Then we get to Tokiomi choosing Rin to be given to the Matou. It is all about what Rin and Sakura can bring to House Tohsaka. Rin is an Average One while Sakura has Imaginary Numbers (also known as Hollow) and while the former is rare the latter is even rarer (as there is only one other character in Fate having it) and unlike Average One status, Imaginary Numbers is also a Sorcery Trait meaning it can passed down the Tohsaka lineage via Sakura. From this point of view, Sakura brings more to House Tohsaka than Rin. This decision leads to Roa being forced to make his move by taking advantage of Rin's anger towards said decision. Hence Roa's return was heralded by blood.

The Infinite Serpent is, in short, a vampiric cult created by Roa to aid his various reincarnations. The reason I did this is that given that Roa is a prodigy genius, he would have realized that his Reincarnation spell has the negative effect of accelerating his, what I will call, Soul Degradation Rate and thus would need a way to regain any possible lost knowledge since in Nasu-canon everything comes from soul; mainly our memories and what unique abilities we posses in life. The leader of the cult when Roa is not there is Cradula whose physical appearance is based on Monica Argento from Trinity Blood and Virgo (Eclipse) from Fairy Tail. The name Cradula is an anagram for the word Dracula.

As for the Zouken part, it was two-fold: 1) he had to have planned out what he was going to do to Sakura since like the Einzbern, he has the same level of access to the Holy Grail as they do so he had to have known that the Grail was corrupted. In the Heaven's Feel Route of Fate/Stay Night, he was able to summon the True Assassin via Medea's False Assassin by using False Assassin's spiritual core to do so. And it was later revealed that Sakura's Imaginary Numbers has a high affinity towards Angra Mainyu's powers. So Zouken has since been planning on making his own version of Grail for his own goals. 2) It was to set up my version of the fourth Holy Grail War, which I will explain below from the masters, their servants and how the war went.

Fourth Holy Grail War Masters/Servants:

House Archibald/Saber Camp: Kayneth El-Melloi Archibald & Sola-Ui Nuada-Re Sophia-Ri/Saber (Fergus mac Róich)

House Einzbern/Lancer Camp: Kiritsugu Eimya (House Einzbern Champion)/Lancer (King Arthur Alter (aka Artoria Pendragon Alter) the King of Storms)

'House' Velvet/Rider Camp: Waver Velvet/Rider (Iskander (aka Alexander the Great))

Fourth Holy Grail War Synopsis:

After being defeated in three successive wars for the Holy Grail, House Einzbern is determined to win the next one at any cost and elects to hire the notorious Magus Killer, Kiritsugu Emiya, to become their representative in spite of his reputation as an unconventional and ruthless hitman. For the next eight years, he prepares the war in the Einzbern stronghold while unexpectedly forming a family with Irisviel von Einzbern, who is to become the vessel for the Grail, and their daughter, Illyasviel. However, Kiritsugu must contend with six formidable opponents, all participating in the war for their own reasons.

From one of the three founding families, the magus Tokiomi Tohsaka wants the Grail in order to find his eldest daughter Rin and cure her of her vampirism, receiving support from the priest Risei Kotomine and his son, Kirei Kotomine, who is also unexpectedly a master in the war. Unlike Tokiomi, Kirei has no direction in life and soon sets his sights on Kiritsugu as an answer to the frustrating lack of meaning in his life.

With Zouken Matou dead due to the actions of the Roa-possessed Rin, Kariya and his brother Byakuya are the new leaders of the Matou clan. The two brothers leave Fuyuki City before the war can start. However, before leaving Kariya manages to convince Tokiomi to name him as Sakura's legal guardian as a precaution in case Tokiomi is killed during the war.

Without the Matou taking (i.e. refusing) their usual slot in the war, the Grail is forced to find a last minute replacement; in the form of a deranged young woman named Run Ru who, thanks to the Grail, is given the knowledge needed to summon her own servant; the legendary 'vampire' Dracula aka Vlad Tepes III under the Berserker-class.

After learning of the war and taken by arrogance, Clock Tower magus and lecturer Kayneth El-Melloi Archibald decides to join the battle to increase his own prominence within the Mage's Association. However, his dismissive attitude towards the radical theories of his student, Waver Velvet, drives the young man to steal Lord El-Melloi's artifact and participate in the war in order to force the Mage's Association to recognize his genius. This leads Kayneth to gain another artifact to insure his place in the war and to gain revenge on Waver.

The seventh and final master of the war is the spellcaster and single mother Elsa Saijou. While reluctant to compete in the war and risk leaving her only son, Saijou Luca alone, Elsa accepts the Grail's call.

Fourth Holy Grail War – changes between Canon and Blutmond:

As you read in the Masters/Servants list, Elsa is the seventh master, not Ryuunosuke Uryuu as he has role in this story yet. With the Matou bowing out of the Grail War for good, the Grail is forced to find a last minute master which comes in the form of Run Ru (from Fate Extra), a deranged young woman who dresses up as a clown (and who also runs a kid's party business) and who is a cannibal. Her servant is Vlad III (the Fate Extra version) however this Vlad is a Berserker (to differentiate him from Lancer of Black) as this Vlad is an amalgamation of all the versions of the fictional vampire Dracula thanks in part to Abraham "Bram" Stoker using Vlad as the basis for Dracula novel.

Kayneth instead summons Fergus mac Róich under the Saber-class. However, like in the Canon, there are still problems between master and servant, problems that Sola gladly takes advantage of. Kayneth is still crippled by Kiritsugu and Sola takes over as Saber's new master, but Kayneth dies when Sola manages to anticipate Kiritsugu's actions in attacking their new base of operations – the warehouse – tricking Kiritsugu into killing only Kayneth. The Feast of Kings instead becomes the Feast of Heroes where Rider gathers his fellow servants and their Masters to hear their desires for the Grail. Caster, under Command Spell induced orders of Tokiomi, starts an attack at the FOH resulting in Rider retaliating with his Noble Phantasm that shocks everyone due to its nature... a Reality Marble. Caster is revealed to be 'dead' but reappears alive and well later on having used a duplicate body to trick every one.

Instead of Caster (Gilles de Rais in the original Canon) going on a rampage, its Run Ru and Berserker who rampage after Risei calls a temporary ceasefire and orders an alliance between the Masters to stop the two. Risei is the one who discovers that Run Ru and Berserker have been kidnapping the citizens of Fuyuki for Run Ru to devour to fulfill her cannibalistic urges. The alliance succeeds in both stopping and killing the two; Assassin (Charles-Henri Sanson) and Lancer (Artoria Alter) kill Berserker but Assassin takes a fatal blow from Lancer as in her mind the alliance was over the moment Berserker was killed, while Elsa was the one to kill Run Ru as the latter had attempted to kidnap the former's son Luca. The war is then resumed with Rider having a climatic battle with Saber but is interrupted by Caster's Elementals, allowing Caster to get close to Waver and force Rider to take the fatal blow to protect his master, resulting in Waver dropping out of the war. Elsa and Archer confront and manage to defeat Sola and Saber; however their victory is tainted due to Maiya's interference in successfully killing Sola but failing to kill Elsa tanks in part to Archer's abilities.

Archer has a climatic battle with Lancer, once more being forced into using her secondary Noble Phantasm to switch her class to Berserker and puts Lancer on the back foot but the latter is able to overcome the Beast Woman with her own secondary Noble Phantasm. Lancer lets Elsa go preventing her master Kiritsugu from targeting the defeated spellcaster. Tokiomi (who has been gradually going insane since Rin's condition happened) uses his command seals to force Paracelsus' compliance to his plans; killing Maiya when he assaults the Einzbern Castle and kidnaps Iri in his attempts to force the Grail's summoning so he can save his daughter Rin from her condition. (This all happened during the Archer vs Lancer fight) Tokiomi instead replaces Kirei in the anime's fight with Kiritsugu while Lancer fights Caster with the same conclusion as canon; her being forced to destroy the Grail by Kiritsugu (though Lancer is successful in killing Caster beforehand) and the Greatg Fuyuki Fire happens as in canon. Kirei, as ordered by Tokiomi, watches over Sakura alongside Kariya who returns one after the war's ends.

This is the Blutmond version of HGW4 and setup the events of Blutmond to follow.

Well that's all I have to say for now. Be on the lookout for the next prologue chapters; Edge Master and Hunters of Roa. RWOL is out this mutha!
