I want to thanks wfkiwi for been the BETA if this chapter and the support that he give to this story.

Something was wrong and Tatsuya knew it, he could feel it. It had been that way since they finished their attack on the blanche base, the sensation that you had in your stomach when you know something was wrong. But as far as he could see, that attack was a big success. Besides the part where the blanche leader lost his arm when Kirihara destroyed a metal door to get in. The same moment that the cowardly leader tried to use that same door to escape. But Jummonji sempai took care of the situation and now that the authorities had arrived, they could leave the base yet this feeling had only grew.

He and the others were about to get into the car when his phone rang and he knew in that moment that it will not be good news.

A few moments ago, back at First High.

'No this can't be possible' that thought was present inside Rin, Sakura and Illya minds as they recognized the dark cloud that is wrapping the girls, and that shouldn't be possible, not in this world.

''President!''

''Miyuki!''

The shouting of some students that had begun moving to assist the girls jerked them back to reality. They will have time to think about that later, now they had to act.

"STOP RIGHT THERE!" yelled Rin as she stepped in front of the students that were running to help their fellow students.

"But Rin sensei, they are in danger!" said one of the students.

"And you will end just like them if you jump in without thinking and we don't need more victims" scolded Illya.

"But we need to do something!"

"And something will be done by us". Said Sakura and as she looks at Shirou whom like the students, didn't know what was happening yet also wanting to do something to rescue Suzune, Mayumi and Miyuki that were trapped inside that dark cloud. "Don't let them get close to that"

Knowing that they must know what that spell cloud is and with the experience of never winning an argument with them, Shirou just nodded. As he saw how his girlfriends ran to the dark cloud and stopped just in front of it.

"I will take care of it." Stated Rin as she traced a diamond in her hand and launched it into the dark cloud, what happened next was something that none of the crowd present expected as the diamond began to shine and a moment later attracted and absorbed all the darkness, revealing for the first time the bodies of the three girls that were. After that, the diamond that had turned black fell onto the ground only to be picked up by Rin. "This is bad, we need to hurry and take them to a hospital and someone contact their families" ordered Rin after she recognized the black marks that began to form on the hands and necks of the girls.

While all that was happening and some of the students moved to do what Rin has just ordered. Shirou took his phone and selected a number among his contacts, deliberating if he should call and tell Tatsuya what had just happened or wait a little longer. He knew that Tatsuya was facing the leaders of this attack at this moment, but he also knew how strong Tatsuya really was and that he could resolve the whole situation alone if he wanted but that would cause Tatsuya to reveal some of his more special skills. But Shirou also knew that the worst mistake that he could make right next to underestimating the enemy was to get distracted in combat.

Looking at how Rin, Illya and Sakura were helping the girls while he could only look on from where he and the rest of the students were. Shirou could only curse his own limitations, as he knew that unlike Rin, Sakura and Illya that were raised to be magus and became geniuses in their own ways. He didn't had the same level of knowledge as they do and even if his own magic is as powerful as theirs, it was thanks to a combination of unique circumstances and his mysteries were not as diversified as theirs.

He finally made the decision of waiting until the girls were taken to the hospital before he would call Tatsuya, giving him more time to finish his current fight. And as the minutes passed like hours, the first police cars arrived. Probably notified by some student at the beginning of this attack, they made their advance following the tactical team that made sure that everything was under control.

The calls for help soon attracted their attention to the 3 girls in school uniforms with three ladies that appears to be teachers in contrast with the students that were with them.

"These girls have been poisoned and need medical attention immediately" said Illya.

"What happened here!" demanded the leader of the tactical police group.

"The explanations can come later, first we need to help the injured now" retorted Sakura.

"No one will leave this place until we know what just happened" was the reply of the leader.

Seeing that it was more a matter of pride and the fact that that police looks like he doesn't like receiving orders from magicians, Rin decided play a new card.

"Listen you moron, this girl is related to the Ten Master Clans if she died and the word come out that you delayed her medical attention that she needed, what do you think will happen to you? Now stop being an idiot and take us to the hospital, you will get your answers after we have handled the intruders"

Not happy to gets orders from a teacher but liking even less the idea of the consequences that he could face when he recognized that it was Saegusa, the one that that short tempered teacher was talking about, he finally agreed.

In a matter of moments, the girls were taken into the ambulances with Rin, Illya and Sakura going with each one of the girls. Just as they were about to leave was the moment that Shirou was waiting to contact Tatsuya.

"Tatsuya, it is me, something had happened"

Shiba home

"In the end we couldn't find anything useful with Sensei" said Miya as she look at her sister.

"From the beginning we never really expected to get something, knowing how that old man is" added Maya.

"By the way sister, are you sure that it is OK for you to be outside the clan complex" asked Miya.

"It will be fine, to be honest I was expecting a good excuse to leave that place even if it was only for a short while, beside I am no longer that defenseless child anymore" answered Maya.

A small slience prevailed between the two sisters, that discomfited Miya and wanting to keep the conversation moving, she began to think about something else to discuss. Over the past years the distance between the two of them had become closer, not like it was when they were kids, but better from what it used to be until recently. And the current situation with Tatsuya that had attracted her sister's interest was something that she still need time to anaylse if it is good or not.

"I know what you mean, this house feels more like a home than any of the Yotsuba complex" continued Miya.

"If I am not mistaken this house also has an underground lab, one of the best in the private sector" replied Maya.

"That is correct but unfortunately no one here can made good use of it." agreed Miya.

"Not even you?"

"You know that my role in FLT was administrative, while Tatsurou was in charge of the technical part of the job"

"All that idiot did was to drive away our best engineers that were subsequently taken by Avalon tech. Gods the only good thing about him was his Psion level, other than that he was completely useless, just like Kouichi" said Maya.

At those words, Miya chose to remain in silence.

"Had you ever wondered if out there is a man that could made us happy? Outside all this business of the master clans, just as a woman. I tell you that I would be happy to retire from the Yotsuba clan head position and live a normal life if I found one real man that can make me happy" Maya slowly started.

"Do you have someone in mind?" asked Miya

"As long as he is not like that loser Kouichi I would be happy, but you know what they say, everybody wants what they can't have. What about you?" Maya continued.

"I would rather fix all my mistakes than look for a man that may never have existed in the first place." Said Miya.

Before they could continue with their talk, they could hear the phone ringing and how Honami answered the call. The way that she ran to where they were; told both sisters that something had happened.

"Miya-sama, Maya-sama, it is Miyuki-sama. Something happened at the school"

And both sisters felt how the blood in their bodies drained from their faces.

Saegusa Mansion

The same feeling that the Yotsuba sisters were feeling is now shared by Saegusa Kouichi after he was informed about what happened with his daughter.

"No Mayumi, not again" was all that Kouichi could think as he hurried to the hospital.

"Dad!" yelled a duo that he recognized as his twin children Kazumi and Izumi. "Is it true that something has happened to Onee-sama!?"

"We still don't know the details but she is being taken to the hospital as we talk" answered Kouichi as he continued briskly to the entrance way.

"We will go as well!" said the twins.

"NO, we don't know if this is an isolated incident or if this is an attack against the master clans, I'd already given the order to increase the security in the complex and you will remain until I say that it is safe."

"But .."

"No buts, do as I said and remain out of danger" and with that Kouichi left the complex, having no idea that he was about to have a meeting that will recall many bitter memories.

Back at the hospital.

As soon as the ambulances had arrived, the girls were taken to the ICU, where they hoped that they would be able to help them. In fact, the medical staff were sure of that since the discovery and distribution of the elixir from Avalon Tech had a great deal of positive effects on magicians when they get hurt and they were hoping that the girl's injuries would be easily healed the same way.

Unfortunately for the hospital staff, the creators of that same elixir were having their own doubts and that is why Rin broke away from the group, to use her teleportation to go back to the Emiya mansion and their workshop.

Once again, she couldn't help but smile at the benefits of having this link with Shirou and the others. This teleportation would had been considered a true magic back in their old universe and would give them the rank of sorcerers for that alone. That or receive a sealing designation for each one of them. Recovering her focus on the current situation Rin took the diamond that she used to absorb the curse that she knew was the cause of the girls unconsciousness and began to study it, after a few tests it was as she feared. She and the others had recognized that particular curse as something that they had studied back in their old universe and that was the strange thing because the magicians of this universe should not have the knowledge to use that kind of curse. Yet the proof that that idea was wrong was right before her, and while even if the cure was something that she could create especially if she received the assistance of Illya, that wasn't the real problem. The real problem will be to determine how a curse that was meant to destroy the magic circuits of the victim is affecting a group of modern magicians that shouldn't have any magic circuits to be affected in the first place. She would need to get back to the hospital and deliver the news, but more importantly she needed to begin studying the girls to determine what is that curse doing to them. But first she must tell her own family that they are fine, by now they must have heard about the attack and even if they know about Shirou and his girl's true levels of power and skill, their family will always worry about their own no matter what.

Back in the hospital.

Maya and Miya were hurrying as fast as their elegant dresses would allow them in the hospital halls, followed closely behind by Hayama and Honami, each one behind their respective masters. When they turned the corner to where they were told Miyuki's observation ward was. Their steps faltered only to stop at the sight of the person that they all knew too well because of the big impression that she left the last time they saw her.

"You!" Shouted Honami as she saw Sakura waiting outside the door and moved in front of the Yotsuba Twins.

While Hayama also took a guarding position. For him the sight of that girl represented something else. That night, Hayama like all the other members of the Yotsuba clan hurried to help in the defense of the complex but unlike the others. He tried to get information on the intruder before he had to face he or her in battle. What he saw that day in the cameras was something that still worries him, because what he saw shouldn't be possible; a young girl of gentle features was sweeping the floor with the best magicians of the Yotsuba clan, the untouchable guardians, yet to that girl they were like simple toys, one by one he saw how that young lady took down everyone that dared to try to stop her with wind, fire and water magic that he had never saw before. She even made a big earth block arise from the ground in the garden under the feet of some guardians that tried to attack her but ended up getting sent flying over the house. Then when only he and another guardian with a kodachi stood in front of the door that led to where the main family of the clan were. The guardian with the Kodachi tried a frontal attack hoping that the speed from his acceleration spell and his blade will work where everything else had failed. Yet to his and the guardian's surprise, the violet haired girl stopped the Kodachi with a Katana of her own that he never saw from where she took out from. Followed by punching the guardian with enough force to send him flying against one of the walls where he lost consciousness. Making the Katana disappear into the air in tiny blue sparks, the girl focused her attention on him who stood in front of the door. He was expecting a magic attack or that maybe she would again use her sword. Unfortunately what she did was worse, she stopped only a couple steps from him and simply smiled at him. Which should not had been anything strange until he realized that he was feeling very tired and lethargic out of nowhere and keeping himself awake was extremely difficult. He fought against the power that told him that he needs to sleep to no avail and soon lost to it.

It was a couple of hours later when he was awaken by some of the members of the clan that were helping the wounded and for a moment he was worried that the main family was killed. Fortunately he saw that that was not the case and from what he heard, that girl came only to deliver a message. The next day when he heard what happened from Maya and Miya he did not know what to think. But there was something that he needed to tell his masters so he requested a moment alone with the twins, when he informed them that that girl used some kind of mental interference to make him sleep and that he could feel a great deal of power coming from her was something that didn't seem to surprise the twins only worry them more. That girl showed herself to be an incredibly powerful and talented magician, adding that she could use a mental interference magic that was Miya's specialty and was powerful enough to overcome him was something that they didn't expect. That only added to the mystery that surrounds that girl. So far, the only people that know about that last piece of information are himself, Maya and Miya.

"Please lower your voice, this is a hospital," smiled Sakura as she turned to see the new arrivals.

"What are you doing here?" asked Miya with slight worry in her voice.

"As a teacher in the school it was my duty to be by their side until their parents arrive" replied Sakura.

"That still don't answer my question" added Miya.

"I was also a witness of the attack, so it is only natural that I'm worried about them."

"And you just happen to be there? Are you sure you didn't had nothing to do with this?" retorted Maya in an accusatory tone.

"Of course not, we will never .." answered Sakura but was interrupted by a new arrival.

"Mayumi!" said a voice that Maya was hoping to never hear again as she turned and saw Kouichi Saegusa had reached where they were.

"Maya" said Kouichi who paled as if he had just seen a ghost. "What are you doing here?"

"Well if it isn't Kouichi Saegusa, in fact I was about to ask you the same thing, What are you doing here?"

"I was informed that my daughter was admitted in after an incident in First High magic school. Don't tell me that you did something to her? Because if that is true I swear that I .."

"Save your threats to some one that is afraid of you, and to answer your last question I had nothing to do with this. But I want to say that it is good to know that you are this late even for your own child, that means that my case wasn't the only instance when you were late"

The tension could be felt in the air, even for Sakura that was the only one of those present that was ignorant of the past of these two and what happened between them.

Just before any of them could say something else a female doctor came out from the room where the injured girls are been treated followed by Illya who was also wearing a doctor's coat.

Not many people knew this outside their family or better said not many cared; but after Shirou, Rin, Sakura and Illya finished high school they went to the university and got their Magic Degrees, in order to be able to back up their work as the seats of Avalon if they ever needed. They realized that while they had a lot of magical knowledge thanks to their previous world memories and the objects that they had been collecting over the years which none in this universe even know about. Now that they were living in a world where magic and science are combined, they decided to try something that would have been an absurdity in the previous lives; go to a normal university to get modern knowledge to improve their mage craft.

In the case of Rin she got a degree in Mineralogy with an emphasis on jewel and crystalline structures. Sakura on the other hand got a degree on Botany with emphasis on crop efficiency. Shirou got Metallurgy with emphasis on alloys and finally Illya got a Medicine degree. In fact, it was Illya that came to this same hospital to teach them about how the elixir works, no one from the hospital staff minded her age and assumed that as a member of Avalon tech she knew what she was doing, it was for that reason that when she arrived with the girls and asked to be allowed to participate in the girls' treatment; no one said anything because they knew that she was not only a Doctor, she also knew a lot about the elixir and had the back up of Avalon tech.

"What can you tell me about my daughter" Asked Miya doing her best to keep her emotions under control.

To Kouichi it was the first time that he realized that Maya wasn't alone and that her sister was there. He had met her many years ago and as the twin sister of his fiancé he did his best to develop a friendly relationship with her, but that ended with the tragedy that happened to Maya and he hadn't seen her since those days. The fact that she had asked for her daughter could only mean two things, that the Yotsuba have a new heiress and that she was in First High magic high school and she also got hurt by this incident. In a blink of a second, he wondered if this meant that the Yotsuba will again show the world what they are capable in the name of revenge when someone hurt one of them as they did with the KunLunFang Institute, but then he remembered that his own child was also hurt and if something happened to her, he will not only disregard what the Yotsuba will do but he more than surely will join them this time.

"We managed to stabilize their condition for the moment, but unfortunately we still need to identify the poison that was used on them and the elixir isn't working on them for some reason" said the female doctor.

"Poison? My child was poisoned?!" questioned Kouichi.

"It is more like a curse that acts as poison" said Illya.

"Please Illya-san do not say things until we are sure about the cause of all this"

"That is why I said, we need to identify the curse in order to create a cure" answered Illya.

"We have no evidence that supports that claim Illya-san"

"We do now" said a new voice that attracted the attention of all those present. Heads turned to see a black haired girl of the same age as Illya and Sakura walked towards them followed closely by three other adults, two women and a man.

"Rin, did you manage to find something?" asked Illya.

"I am afraid that I did and no one will like what I found from the sample that I took"

"Sample? What are you talking about?" asked the female Doctor.

"I would like to hear about that as well" asked a young men in suit that just arrived followed behind by Shirou and Tatsuya and another man in suit.

It was in that moment for the first time in years that Tatsuya and Miya where in the same room and the fact that both froze when they saw each other and the story behind them created a tension that could be felt for all those present.

For Tatsuya, he was now in the presence of the woman that had marked his existence as useless and thrown him away as a defective product. Even in that exile he had worked very hard to try to prove that he was worthy to be her son, to be accepted by her, loved by her, only to have that illusion destroyed when those men came to kill him. After that his world changed, he changed; for the best he hoped; for years he trained to protect his life and his new family who are possibly the strongest magicians on the planet. He pushed himself to surpass his limits getting ready for a possible confrontation with the Yotsuba, only to find that she didn't care; she never did. Those men that killed his grandfather figure came under another person's order for an internal conflict inside the Yotsuba and that woman didn't even know about that because she never kept in contact, she never cared for him and now she is right before him.

For Miya, it was her first time seeing the face of the child that she had abandoned all those years ago, all those years thinking about him, how he will look, if he was fine and safe. All those times that she wanted to just be there by his side only to swallow those desires, believing that her absence was the best for her son, that her absence will allow him to have a normal life. Even when the new magic system appeared and Kogoro send a message telling her that Tatsuya showed great deal of talent for it, she still refused to made contact fearing the reaction of the clan because they considered that new system as a joke, it is an irony that the new system kept growing stronger each day and she didn't know the real power of her son and that was something that should be normal for a mother. Oh god all that she wanted in that moment was to hug him with all her being, but she could see that he had his guard up, he didn't trust her and she couldn't blame him for that.

"And who are you?" asked the doctor

"I'm inspector Chiba and this is detective Inagaki, we've come here to learn about the details related to the attack at the First High magic school and the condition of the victims" replied Inspector Chiba.

"I am Kiritsugu Emiya, I came because my family was in the school when the attack happened".

"You are the CEO of Avalon tech!" stated Honami in surprise.

"All that is very interesting" said Kouichi losing part of his patience. "But can you go back to the part where you said that my daughter was cursed".

"As I said we have no evidence of that" said the doctor.

"And as I said I am sure of that, I am sure that Rin can confirm that" retorted Illya.

"I can, but I believe it will be better if we move this conversation to a more private location," said Rin.

Soon the large group of people moved to a waiting room close to the observation room. Where Rin dropped a red jewel that created a small boundary field. That surprised everyone other than Honami and the others that had already seen this before.

"This will give us a little more privacy" explained Rin as she looked at the group.

"It is as we feared?" asked Illya.

"I am afraid that that is the case" replied Rin as she showed them the black diamond. "This diamond had the curse that affected the girls sealed inside it, don't worry it is safe now that it is sealed inside the crystal, but I am afraid it is the nature of the curse that is causing the problem to deal with it." Said Rin as she gave the diamond to the doctor.

"What do you mean?" asked a worried Miya.

"Also with what right did you have to take away an evidence of the crime scene, that is a very serious offence" added detective Inagaki.

"I took the sample to the seats of Avalon in person and asked them to analyze the sample, I am sorry to say this but even if the best lab technicians of the police and this hospital work on this sample first they would need months to even begin to understand this curse while the seats of Avalon already identified it, sorry but that is the truth"

"And what about the suspects that you killed?" asked again the detective.

"They opened fire against my students and it was my responsibility to do all that was in our power to defend them"

"But even them.."

"Listen detective, do you want to know what will happen? If you raise charges against us the full investigation will show that this attack is related with that group Blanche that had been under the radar of the 10 master clans and the Self Defense Force, for some time and when the investigation show that the weapons that they used are military grade and as you know no military weapon can be obtained by persons or institutions in Japan. That will indicate that a foreign power participated in this attack, you will expend many hours following that clue and when you are one step to finding something important the defense ministry will take over the case, thanking you for your hard work and the case will be closed and our participation will be declared as self-defense and you would have wasted lots of time for nothing" interrupted Illya.

"We don't have time to waste, did you say that you know what is happening to my child" continued Kouichi.

"You are right" said Rin. "I am afraid that Suzune, Mayumi and Miyuki are in a very unique situation, because the curse that is affecting them wasn't meant for them in the first place" When Rin saw the confused looks in the parents' face she continued. "This is a curse that was meant to spread through the magic circuits of the victim."

"But how is that possible, Miyuki and the others are modern magicians, they do not have magic circuits" added Miya with concern.

"No, but they do have a field of magic calculation area" said Sakura as she and the others began to understand where this was heading and they did not like it.

"As you may know, the magic calculation area exist in all modern magicians brains, this allow them to manipulate the Psion particles in order to use their magic, the Magic Calculation Area's transforms the imagined reality into data and produces a Magic Sequence for the desired spell. Generally speaking, target coordinates, interference strength and ending requirements are all set as variables to be executed by the Magic Calculation Area; all other essentials are incorporated into the Activation Sequence, which is then sent to the Magic Calculation Area and translated into a Magic Sequence. In short, the target and power of the spell are determined by the Magician's mind whereas the nature of the spell is determined by the Activation Sequence." Said Rin. "While the magic circuits are a pseudo-nervous system that spreads itself through the human body and what qualifies a person to be a magus. Their normal functions are to act as paths that convert Life Force into magical energy, but humans learned how to control it and use it to perform mysteries. They are the bridge which connects the material world to the astral plane, and are within the magus's soul, and what is found on the body is just a physical expression of them that stretches itself throughout the body in a fashion similar to the nervous system"

"What that have to do with anything?" asked Kouichi with worry.

"That means that they never were the intended target for the curse, it was the Thaumaturgy users" answered Illya.

"But if that was the case why were they affected" asked Maya.

"After we finished dealing with the attackers, Mayumi, Suzune and Miyuki came to where we were, it looks like the enemy attack was focused on the second course facilities and they were worried, it was in that moment that they saw someone coming towards them wearing the school uniform, he walked in a strange way and when he fell to the ground, the girls that were closer to the unknown hurried to help and it was in that moment that the curse was released."

"But that means that person should have an antidote in case he was infected, if we take a blood sample we could replicate more" stated the doctor only to see Rin shaking her head.

"That person didn't received the curse because he was already dead when he walked towards the girls" said Rin.

"I hope that you aren't saying what I'm thinking" frowned Inspector Chiba.

"He was a walking dead been controlled by a necromancer" answered Rin.

"Damn!" sweared Chiba, he like all the present knew that the magic to control the dead was a forbidden magic that was also illegal in many countries, yet there was a group of Taoist magicians that still practice that dark art, and they were in the Great Asian Alliance, he didn't like where this case is heading.

"But you can do something Right? You found the curse" asked Honami.

"And that is the current problem, this curse is the Basilisk curse and it works by affecting and moving through the magic circuits until it arrive to the soul of the victim, then it will petrify it and when that happens it will be the end because with the soul petrified the body can no longer survive. But in this case for some reason it is affecting their magic calculation area and to be honest I have no idea about what could happen in this case" explained Illya.

"But the elixir should be able to cure them" said Miya remembering her own experience.

"The elixir works by helping to restore the physical body of the living things by stimulating cell regeneration, the magic circuits and magic calculation area despite been linked to living persons they exist in a metaphysical way and even if the user get hurt by over using its power; the elixir help the physical body but can't interact with the metaphysical plane, and for that the elixir can't reach them"

"Then what option do we have?" asked Maya.

It was for a moment but Shirou, Illya, Rin, Sakura and Tatsuya looked at each other's eyes for a second.

"We plan to ask the seats of Avalon to stop all that they are doing and focus in finding a cure before it is too late" said Rin.

"What do you mean with too late" asked Miya with worry.

From the corner of his eye Tatsuya could see how his, no, how Miyuki's mother worry about her and he couldn't help but feel confused. For many years he wondered what would happen if he ever had to face her in battle, but after what Sakura told him that night he didn't know how to react, what to think, but now he realize that he didn't feel anything, no connection, no sympathy, nothing. And while he was worried about Miyuki and the others, he also knew that Shirou and his big sisters will resolve the situation by doing something impossible, just as they always do.

"The Basilisk curse is lethal in five days, but in this case we can't be sure, we could have more time or less, for that reason we can't waste more time" said Sakura.

"All this is too much to take in. How do we know that we can trust you? That you can save our children?" asked Kouichi

"We can't make any promise because this is a situation that no one have seen before, the only thing that we can promise you is that we will do our best" replied Sakura.

"And we should believe you?" asked Miya

"I do not mean to be disrespectful but neither of you have any other choice" said Illya.

"We can take them to our personal doctors, some of the best in Japan" answered Honami.

"You don't seem to understand that this is not a disease that was created in a laboratory, this curse existed and was lost around 2000 years ago, no modern medic and magician would be able to understand it in time to do something" added Rin.

"Still.." began Kouichi again.

"Listen we do not have too much time, if you are going to made the decision that will save those girls lifes, it have to be NOW!" stated Illya forcefully.

It was in that moment that the three members of the master clans look at each other. In the last few minutes they had received so much shocking information and revelations that they didn't know what to think but they know one thing, they were vulnerable and completely dependent of the persons in front of them, and they weren't used to that feeling, yet for the sake of their girls they have to believe in them once.

"Ok, but we will be close to our children and we will talk with the seats of Avalon" agreed Maya.

"I don't think that that will be necesary" said Kiritsugu, speaking up for the first time. He was well aware of who were the people that were in front of him and he had his guard up in all ways in order to protect his family but now he did not want where this talk is heading.

"That is the only way we will agree to something like this" added Kouichi

"It is ok, Otto-san, I am sure that under this circumstances the seats of Avalon will agree to meet them in person" said Illya.

"Then I will begin to prepare a special room so they can work here with the hospital staff" said the doctor.

"That won't be necessary because we will be taking them to Avalon Tech. The equipment that they have there is far beyond that of any the government or this hospital have" replied Rin.

The doctor was about to say something but she knew when she saw the faces of the parents of the girls that it would be a lost cause and went to give the orders to get ready some of the Ambulances to take the girls.

"What about Suzume? Have her parents arrived yet?" asked Shirou.

"She lost her parents when she was little and had been emancipated for some time now" answered Tatsuya remembering the talk that she had with him.

"Why don't you go ahead and get ready everything, Aoi and I will deal with arrangements here and will follow you later" said Irisviel that until that moment had remained in silence, studying the situation.

With no other word, everybody began to move.

1 hour later, Avalon Tech.

The main complex of Avalon Tech was on the borders of the city, close to the mountain where the mansion that the Emiya family lives. This allows them a great deal of privacy, especially considering that the Emiya family had acquired a great portion of the forest and land around their mansion and company with the reason of preserving the nature.

In any other day the usually quiet place will have the staff working as usual, but today it was different and everybody were in a hurry, trying to get ready for the arrival of all the personels that were coming.

"We don't have time to waste, this is an emergency and lives are in danger so hurry up" ordered Ushiyama, the operations director of Avalon tech.

It was a few minutes after and the ambulances arrived, followed by the cars transporting the parents of the girls. Shirou, Tatsuya and the girls had arrived an hour early in order to get everything ready and inform the staff about the current situation. So when the injured arrived they were taken to the special room that had been prepared for them. On the way while following her daughter Miya could see many familiar faces, while she didn't remember their names she knew that at one time they worked at her company but her late husband pushed them away. The only person that she knew by name was Ushiyama. And now the same people that her idiot husband rejected are working in the company that replaced them as the number one company in magic tech in Japan and are now helping to save her child.

With great care, Miyuki, Mayumi and Suzune were taken inside an enhanced laboratory room with many unknown instruments where Shirou's group were waiting for them, followed by their parents.

"Well we are here now. Where are the seats of Avalon, we agreed to this because we were told that they will handle this case in person and I need to see the kind of people that will hold my daughter's life in their hands" demanded Kouichi.

"As much as I hate to agree with Kouichi-san here, I would also like to have some words with them" added Maya.

"I believe that that won't be necessary," said Illya.

"What do you mean with that, we agreed to this under that condition" said Honami.

"I believe what my daughter is trying to say is that the seats of Avalon were present in the hospital and heard everything that you said" Interrupted Irisviel.

All the people that were outsiders to the secret remain in silence for a moment processing what they just heard.

"You? One of the seats of Avalon? And which one of you is the Lady of the lake?" said Honami incredulously.

"In fact that would be me" replied Rin proudly, as the members of the master clans keep looking at her, like they were expecting that this will be a joke.

"The Fairy of Avalon?" asked Kouichi. Only to see how Sakura rise her hand a little.

"The Blacksmith of Avalon?" It was Miya's turn to ask, when she saw how it was Shirou the one that this time rise his hand a little.

Looking at all those present she could tell that they were serious, looking at the last young lady of the group she just asked "The Apple of Avalon?"

Illya just nodded with her head. But then Miya realized something very important. Some one that was missing. "But who is Silver?"

It was in that moment that Tatsuya took just one small step forwards, but that was enough to made them understand who he is. But to Miya it was something else, because it was the first time that Tatsuya recognized her words and reacted to them. But more important is that she had confirmed that her son was having success in his life and that he already was someone very important. The part of her being that was his mother felt very proud of him, but when she recognized that he achieved it without her, with the support of a new family it made her feel very down.

"Listen we understand your feelings but now the time is of the essence" stated Shirou attracting the attention of everyone.

"We need to request that all of you remain here, I know that you want to be close to them but to be realistic you will jump at anything we do and that will make us waste time that we don't have" added Rin.

"There is a waiting room in the next hall, you can wait there and we will keep you informed" said Aoi.

Both groups, the Yotsuba and the Saegusa didn't like it but knew that it was their best option.

Taking the girls inside, Shirou, Tatsuya and the girls closed the doors. "Well lets get started"

Time skip, 3 days later

It had been three days since the group arrived to Avalon tech and things haven't changed since the first day. The seats of Avalon had not come out of the special room in all that time, while the parents waited outside; refusing to leave their children. It was when Irisviel offered their mansion that was just a few minutes distance away so they can take turns and rest while the others remain here with the promise of calling them if there is any news, even then the parents only rested outside for not more than a couple of hours and then return to the waiting room.

It was at the end of the third day that the door was finally opened and the seats of Avalon came out, they all looked tired and worn out.

"We have some news for you" said Illya tiredly.

"Did you managed to cure our children?" asked Kouichi.

"We are almost there" said Sakura

"What do you mean with almost" said Maya.

"For the last 3 days we had worked to stop the advance of the curse, and now we have a theory about what we can do to purge the curse from the girls, but it will be dangerous and we will need your permission," said Illya.

"Why" added Miya.

"Because the only thing that we believe can save the girls will require a never used before procedure and we don't know if there will be secondary effects" said Rin

"What do you mean by that!? What had you been doing for the last 3 days?" asked Kouichi.

Tatsuya that in all this event had only talked when it was necessary due to his own emotions began to remember what he had learned in the last few days.

Flashback

They had just closed the door of the lab where the girls remained unconscious as they moved to their beds.

"Do you have any idea about who could do something like this?" asked Tatsuya.

"No but in this moment that is not important, we need to save these girls and time is against us" said Shirou while looking at Rin and the others. "I think it will be for the best if we don't waste time and use our best card in this matter" Rin and the others just nodded.

"Lets do this," said Illya and she stood by the head of Miyuki's bed.

"The sooner the better" said Sakura as she stood at the same position in Mayumi's bed.

"You better get ready Shirou" said Rin as she did the same with Suzune.

"What are you talking about? What are you going to do?" asked Tatsuya.

"We are about to show you something unique" said Shirou as he stood in the middle of the room. "This will take a lot out of me".

What Tatsuya saw was something that he had never seen before, yes he had seen Shirou use his trace magic before, in fact that is how he got the idea behind the anti-gravity magic that allow the magicians; modern or Thaumaturgy user to fly, but those were normal swords. There was a time in the Okinawa incident all those years ago, the weapons that Shirou used to destroy the enemy fleet were like nothing he had ever seen before and their powers were amazing but the more important part was during that event with his elemental sight he was unable to analyse them, to him they were an unknown and that fascinates him, he had asked Shirou what were those swords and the only reply he got was "They are for special situations".

But what he was looking at now was something beyond amazing, it was a mystery beyond anything that his siblings had ever shown him, those projections weren't swords, they look more like scabbards, three golden and radiant scabbards that released a mysterious energy that he had never seen before, and like the special swords of Shirou his elemental sight was useless to determinate what it was.

Once the three mysterious scabbards were ready over Mayumi, Suzune and Miyuki; they become responsive to his big sisters' orders as they moved according to their hands movements while Shirou looks like he was exerting a large effort.

"Keep it like that Shirou, just a little more and when are done we can have some rest" said Rin.

"What is that thing?" asked Tatsuya.

"That thing is Avalon" said Shirou.

"As in the name of our company?" asked Tatsuya.

"No, as the name of the scabbard of King Arthur's Excalibur. That Avalon, the Everlasting Utopia" Answered Rin.

"What?!"

"We had told you that we had been collecting many ancient magic artifacts from the world that no one else knew existed, we even shown you the Dead Sea's scrolls and Merlin's books" said Rin.

"But that is completely different from this, I can't even began to understand what that scabbard is made of, not even with my elemental sight, so I want to know why you didn't tell me about that?"

"We told you about all the other artifacts and relics that we had found, but Avalon is special because it is related to someone that was very close to us and is no longer in this world" said Sakura.

"So you named the company Avalon for that person?"

"Actually, My mom saw one of those old movies about knights and magic from a long time ago and she liked the name and because the money to create the company came from her Family she ended up deciding the name. Whether that was a coincidence or divine intervention, we don't know" replied Illya.

"Could we leave the explanations for another time, because keeping these three projections is not an easy job" gritted Shirou.

With their attention back on the mission ahead of them Rin, Illya and Sakura took control of the projections while Shirou kept them in existence. They began the process to conceptualize them inside the body of the girls. In fact the plan was something simple, conceptualize copies of Avalon so they could cure them from the curse and because Miyuki and the others aren't linked to Shirou with the golden chains the copies would banish in an hour and by them their problem should be fixed.

"Something is wrong," said Shirou with a worried voice.

Or that was what they believed.

"It isn't working, I feel the projections and they are sending their power to the girls but I don't feel any progress on them" informed Shirou.

"That can't be" said Illya as she use her structural analysis on Miyuki, Rin and Sakura did the same. "What is happening? This isn't right"

"We need to find out what is happening and why" said Rin.

That is how what they expected would be the simple solution to their problems became a non stop research for the last three days to determine what is happening and how to fix the problem to save the lives of the girls.

Tatsuya stood there watching how his sisters worked, medicine isn't his strong point, that is Illya's and Rin's strong point and all that he, Shirou and Sakura could do was support them. He took the opportunity to learn more about the real Avalon and its powers and it was in that moment that he learned something new, Noble Phantasms, when they told him about the true nature of Avalon and how there were at a time more of them, Tatsuya didn't know what to think, a crystallized miracle superior to all magic no matter the system, that was something incredible and from what he remembered when he used his elemental sight on Avalon he was unable to even read it. As is Natural in a born researcher, he wanted to know more about them and asked Shirou if he could show him more and if there is more out there. The answer that he got was not what he expected.

"While Rin, Sakura and Illya had weapons made based on noble phantasms, in this world I am the only one that had a real noble phantasm. If the day arrive when you see someone with a noble phantasm walking towards you, you either escape with all your strength or fight like your life depends on it, no holding back because even with your regeneration and all your power I can't guarantee that you will survive a fight with someone that has a noble phantasm" Said Shirou with a seriousness that he had never seen before with a look of loss in his eyes, as if he was remembering something. Whatever that thing may be he chose to leave the matter in peace, It was in that moment that Illya and Rin walked towards them.

"We believe that we have found a solution, but it won't be easy and will need sacrifice and commitment" said Illya.

"We already decided that we would do everything in our power to save those girls" said Shirou.

"Not we, just one of us, in specific it has to be you Tatsuya-kun" said Rin.

All of them turned to look at Tatusy and the only thing that he could say after he saw the looks on their faces especially that little evil smile on Illya was "What?"

End Flash back

"For the last three days we had been working on a cure and we managed to find it, the problem is that it can only be applied in a standard way" said a tired Rin.

"What do you mean?" asked Kouichi.

"We already had a method that was able to cure that curse, and if the girls had been Thaumaturgy users they would have been fine a couple hours after we arrived, but unfortunately that is not the case and while we had managed to confirm that our method can cure them because it stopped the advance of the curse through their bodies, we still need to find a way to apply it in the affected area and while we have managed to find a way it won't be easy and it could have some risks" answered Illya.

"And what would that method be?" asked a worried Miya.

Looking at each other for one last confirmation Rin answered.

"We plan to implant a set of magic circuits on each one of them, to use them as a base to deliver the cure".

"You what?" asked Kouichi

Seeing that all the presents will need a better explanation Rin walked to the small table that was in the waiting room and took a magazine and a flower vase that were on it.

"As we explained before, the curse was located in the magic calculation area, fortunately it has not moved to a critical area, but at the same time that is also what makes it harder to reach"

"How is that possible?" asked Maya

"Conceptualization" answered Rin when she saw the look on the faces of the parents. She continued "The conceptualization is the idea behind the CSD or Conceptual Store Device, that is a magic tool that only Thaumaturgy users can use, it works by taking a catalyst to store objects" as she said that she took the flower vase, as she put some mana and proceed to integrate it into the magazine right in front of all the presents. "As you can see I just 'store' the flower vase by reducing it to its basic concept and include it into the magazine concept, while they still are a part from each other they reside in the same space time just that in another dimension that many call the Astral plane. In this state the time flow have stop for the flower vase and when you restore it will be in the same state as the moment that you place it in, but on the other hand if something happened to the magazine the flower vase will also be lost" said Rin as she took the flower vase from the magazine.

"Under normal circumstances a Thaumaturgy user would need a magic tool to do this but it will be limited by the capacities of the tools, but if the magician is a master of this spell he or she could turn any object into a catalyst and store almost anything that he or she wanted into it" added Sakura.

"But what does this have to do with our children" asked Miya.

"Whoever made that curse is a true master of this spell" said Illya

"But that means" said Irisviel who was also present and understood the meaning behind the words of her daughter.

"That somewhere out there is a master of Thaumaturgy that is not any of us." Confirmed Illya. "But we will deal with that problem later"

"At first we believe that if we conceptualized the object that could cure them inside the girls that would had been all that was needed and the curse would had been eliminated," said Rin. "Unfortunately that wasn't the case, because even if the magic circuits and magic calculation area exist in a metaphysical way inside the body, they are located in different layers" continued Rin.

"But why can't you just do that?" asked Miya.

"Because the magic calculation area of the girls already had the curse in it, under normal circumstances you can only conceptualize one object at the time inside another. It was only thanks to the incorporation of the modern technology that we could add an index in the CSD that allows the user to store many objects in the tool, but that was something that magus behind this curse didn't use. For that reason the magic calculation area of the girls can only store the cure at the moment, that leaves us with the only option of the magic circuits" explained Illya.

"But is it even possible? Having both systems in their bodies even for a little while, so you can use the cure?" asked Kouichi.

"It won't be for only the timeframe of the treatment, once given the magic circuits will remain with them forever, any attempt to remove them will be fatal" warned Illya.

"But what will happen with their future? Is it even possible to use modern magic and be a Thaumaturgy user at the same time? How do we know that there will not be secondary effects" asked Kouichi.

This was the moment that they knew will come and that they had hoped they could avoid, especially because it involves their little brother, but they had talked to Tatsuya and he had agreed to this. With a final nod, he confirmed his decision to the others.

"Because there is already a precedent, a boy that can use both systems" said Sakura.

That attracted the attention of all in attendence, especially two twin sisters's attention when Tatsuya walked to the center of the room.

"I was born as an irregularity, a magician that can't use his magic, that caused a great deal of stress with my blood related magician family so they sent me away so they could focus their effort in the other young family magicians that could control their magic." He took a little deal of pleasure when he saw his mother lower her head at his words, but he continued. "In those times the magic circuits and the Thaumaturgy system were still unknown, anyway after some special circumstances I came under the care of the Emiya family, it was later that they found that for some reason I had both systems fighting inside my body for dominance, that is why I had the capacity to use both systems but neither at the same time. But thanks to my big brother and sisters that found a way to create a stabilizer between the two systems and use it on me, thanks to that I could overcome all the past problems. If you are wondering how this will affect the girls, so far we believe that the modern magic system will be the predominant and the Thaumaturgy the secondary because that is the one that the girls had been using for years now"

"Stabilizer?" asked Miya. After hearing that last part she needed to know, what she missed that could have made the difference in her family and her relationship with her son.

"A relic" answered Tatsuya.

"Relic!?" Miya, Maya and Kouichi were surprised to hear that. A relic is considered a great treasure that many would be willing to kill in order to get their hands on it, not only that but they were sure that the Great Asian Alliance would be willing to do anything, even declare war if that means that they could get their hands on even one of them. To know that they not only managed to get one is incredible but the fact that they used it to help Tatsuya was mind blowing.

"Are you trying to tell us that you used a relic to help a kid that just recently got under your care? Just like that" asked Kouichi , not knowing the full story of Tatsuya's past.

"It was the right thing to do, so why are you so surprised?" asked Shirou in a matter of fact tone, as if what he just said was normal in the world. That left those outside the Emiya Family even more surprised.

"Wait a minute, did that mean that you have more relics here and you will use them to help Miyuki and the others" asked Maya, while she was worried about Miyuki, as the leader of the Yotsuba she still needed to get as much information as she could about the relics that the Emiya appears to have.

"No, finding a single relic was already a lucky strike that even today we are still trying to find more" said Rin.

"Then how?" asked Miya

"We will use the copies that we made based on the one that we used with Tatsuya-kun" answered Sakura.

With those words, a silence settled across the room, as those present were trying to come to terms with the words that the violet haired girl had just said, replicating a relic, that was one of the most sought after if not the most sought after mysteries of the magic world, and this young woman had just said that they managed to do it, as if that was something normal.

"How is that even possible?" breathed Maya.

"You will have to ask Shirou-kun here, because he was the one responsible for identifying and reproducing the materials as well as the internal structure and the manufacturing process" said Rin proudly, pointing at her boyfriend.

Something that was easy with Shirou's level of structural analysis.

"Even then, they are just like any other object until the magic script with the sequences are added, and you girls are the only ones on the planet that could do something like that" continued Shirou.

"But if you could do something like that, then why haven't you made it public? You could be at the top of the magic world not only in Japan but in all the other countries as well" asked Maya disbelievably.

"We haven't found a way to create security measures to prevent them to be used in the wrong way, this world already have too many weapons and it is changing too fast, we may not be able to control other countries making war with each other or if in the future someone else discovers a way to do the same as us, but until that happens we will try to develop our magic and tech to help the planet, not destroy it" answered Shirou calmly.

While Kouichi was trying to understand these young people that were right before him, Miya and Maya where remembering that interesting night when they had met this Sakura girl, could it be possible that she was saying the truth about her ideals and reasons to help Tatsuya? Did all this people share her ideals and point of view?

"What is your answer?" asked Illya

"The situation hadn't change isn't it? So what other choice do we have? Do what you must but save my child" Said Kouichi, with the Yotsuba twins nodding in agreement.

"We will need time to prepare and rest because this procedure will require a lot from us, we will began in 10 hours" said Rin.

And with that the young people, they had just learnt are the seats of Avalon, left the room.

"I suggest that you rest before you join them, we can take you to our home if you want." Said Aoi.

"Thanks, I will also call my twin girls, I had been keeping them informed of the situation of their sister and it is time for today's call" said Kouichi.

"Wait a minute. Did you said that you had informed your home about all that had happened?" asked Kiritsugu with worry.

"Don't worry, I just told them that the seats of Avalon are taking personal care of Mayumi, I didn't mention their identities" answered Kouichi who understood the reason of that question.

"We also did the same in case you are worried" added Maya.

"Thanks, but I am afraid that you may not understand the real implication of what will happen. All of you are about to see a miracle happen, not only a real relic that is inside our son will be used, but three new relics will be created, these artificial relics will also be integrated within these three young girls, if word gets out you can imagine the kind of danger that they will be in. So I ask you that you keep this information a secret" he proceeded to leave the room, leaving the Miya's group to comprehend the scenario that he had just planted in their minds.

Time skip

The time mentioned to get everything ready had passed and we now see our heroes getting ready to put an end to this event.

"Are you sure that this is the only way?" asked Tatsuya.

"Unfortunately it is, do you have any problem in doing this?" questioned Illya

"No, I mean I want to help them but this will change their lives, this will made her like .."

"Like you?" asked Sakura, Tatsuya only nod.

"We had this talk before Tatsuya, about how special you are, but in this moment this isn't about you or about any of us, it is about how someone tried to kill these girls and take away their future, we need to do this or it will be too late." Reasoned Rin

Reaffirming his decision Tatsuya just laid on the bed that was in front of the beds that had the girls. At one side of his bed, we can see the metal grey copies of the three relics resting on a table. Getting ready for what is about to happen Rin, Illya and Sakura surrounded Tatsuya as Shirou began extracting the original relic from Tatsuya's body. Because the first time that they conceptualized the relic and place it inside Tatsuya body, they did it in the core of his magic's circuits they knew that if they completely remove it they would be damaging Tatsuya beyond the capacity of his restoration spell. So they didn't completely remove it, only to the extend with some of his magic circuits still connected to the relic. It was in that moment that Rin, Illya and Sakura placed their hands over the relics, one for each of them, the copies began to levitate and were guided closer by the girls' hands to the original relic. Then they proceeded to send some of their mana to the copies that each one had, for a moment it seems that nothing is happening but soon the copies begin to glow covered in the girls' mana. But they weren't done with that as the copies that were covered in mana began to have that mana moving towards the original relic and have their energy making contact. The density of the mana that is been used on this connection was amazing but so were the girls that were using their own mana to make it possible. Soon the minutes begin to accumulate and nothing seem to be different, but as more minutes passed the copies of the relics began to glow even more, soon the glow began to take its own color, one was yellow, another was green and the final blue.

"Lets move to the final part." Said Rin as each of them moved to be in front of their patients as Shirou returned the original relic inside Tatsuya's body. As this happened each of the girls began the process to conceptualized the copies and put them inside the body of Mayumi and the others, a few moments later they were done.

In that moment Miyuki, Suzune and Mayumi began to violently convulse and scream, but another thing was happening at the same time and that was what the Seats of Avalon were waiting for, the dark marks on their bodies began to disperse, once all the marks disappeared the girls stopped thrashing and begin to breathe normally.

"It looks like we succeeded" cheered Sakura.

"Now what?" asked Shirou.

"Now we tell their families so they can stop worrying and then we go and get some rest" answered Sakura.

"Lets just hope that there will be no more surprises for a while now."

Little do they know that the surprises that were awaiting in the future were only beginning and that soon a ghost from their past will pit them again in the frontlines of a war that not even the magicians of this era could imagine.

Hello. It had been some time.

First of all I want to apologize for the delay of this chapter.

Second, I want to reveal some key parts of the next stage of the story, beginning with the identity of the servants.

Gilgamesh- Archer

Morgana - Caster

Shielfrid -Saber

Spartacus - Berserker

Hector - Lancer

Attila the Hun - Rider.

Semirami - Assassin

Note: I choose these servants before I saw the last anime fate stay night apocrypha and the only one that I change was Semirami to include her.

Finally, as you just saw I made that Rin, Illya and Sakura use their energy to help Mayumi, Suzune and Miyuki but I never mentioned who was help by who. The idea behind this is that because they had to use their own energy to activate the copy of the relic and that affect the process. Therefore, that leads me to two option.

The number one is that nothing happen and beside the fact that they will had to learn how to use some of the basic spells in thaumaturgy, nothing changes in their lives.

The number two is that the relic that now is part of them was affected by the magic of the girl that activate the relic and for that reason Mayumi, Miyuki and Suzune develop an affinity to the magic of the fate stay night that activate the relic that now is inside them, and for that they will need a mentor, the question is who will be the mentor of each of them.

Could it be that Suzune become the apprentice of Rin or maybe Illya?

How about Miyuki leaning from Sakura or how about Illya and she will be teaching her more than just magic (couch*seduceherbrother* couch)

And Mayumi, who could be her mentor, Illya? Sakura? Or Rin?

So what do you think? Should it be the option one where nothing happen? Or the two when Mayumi, Miyuki and Suzune get each a mentor and if that is the case who should be the mentor of who? You can vote for whoever you want.

I will take in account the reviews with yours opinions to determinate that part of the next stage.

Until the next time.
