Chapter 1: 4th Holy Grail War

In Germany, more specifically Einzbern Castle. A woman can be seen running in the hallways going to another room, she opened it and saw a man with black hair and black clothes. This man is none other than Kiritsugu Emiya.

Woman: "Master Kiritsugu!"

He looks up to the woman.

Woman: "Your child has been born!"

He then went to the room to see his child and wife. It was a master bedroom with a lot of windows, to say the least. Kiritsugu can be seen looking at the snowstorm from the window. The woman looks at her baby and this woman is Irisviel Einzbern.

Irisviel: "She's so cute, she's adorable and so small and so very delicate... Look Kiritsugu, she has your eyes too." *pant* *pant* "She's beautiful... I'm so happy to give birth to her."

As she looks at her daughter, Kiritsugu started talking in a grim manner.

Kiritsugu: "Iri... I will be the cause of your death..."

She gasped for a bit but she smiled and looks at their unnamed daughter.

Irisviel: "I know. The Einzbern family has been dreaming of this day. It is the very reason why I exist. When I came to know your ideal, I made your wish my own. You made me who I am today. You have guided me to my path. You offered me a better life than a simple puppet..."

Kiritsugu contemplates the whole thing as the love of his life, Irisviel. He doesn't want to kill her but sadly the fates are cruel.

In another location... Torino, Italy. In one of the buildings, there were three men inside as they discuss something about the war in three years' time.

???: "A command seal?"

Tokiomi: "Yes, the mark identifies you as a participant of the Holy Grail War. A stigmata that allows you to have the power to control a Servant."

Tokiomi showed his own command seal to Kirei located at his right hand.

Tokiomi: "This one, Kirei Kotamine."

~~

Kirei: "The Holy Grail War..."

He looks at his hand and there it was, a command seal similar to Tokiomi.

Kirei: 'The battle to perform ancient miracles. But why me?"

Tokiomi: "Normally, those chosen by the grail are masters to their servants are experienced and talented mages. It is highly unusual for someone like you who doesn't have connections to magic to be chosen to participate."

Kirei: "Heroic Servants... I still find it weird to summon and command a hero of the past to fight for me. "

Tokiomi: "Of course, I know all this is hard to believe but every hero from every age or nation will come back to life in the modern world killing each other to vie for supremacy... That is the Holy Grail War."

???: "Also there is also an unspoken agreement to keep this all a secret. To ensure this rule is kept, someone from the holy church will be sent as an observer."

Tokiomi: "Yes, that was the rules but for the time being. In this Holy Grail War... Someone else will take your role as the Overseer, Risei."

Risei: "What do you mean?"

Then the door opened up to see a man in his late 20s to early 30s and his butler. This man is known as Regis Trevelyan, head of the Trevelyan family of mages. When Risei saw him he and Tokiomi bowed down.

Tokiomi: "It is nice to see you again, old friend."

Regis: "Old, huh? Good to see you again Tokiomi."

Risei: "Sir Regis. It is an honor to meet you."

Regis: "And you must be Risei Kotamine, I have heard about you being the supervisor of the 3rd Holy Grail War. You don't mind me if I take the role of Overseer in this."

Risei: "Of course not. After all, what you and your family had done to the church and the mages, it is the least I can do to repay your efforts."

Regis: "Well, I thank you for that. And this is?"

He shows at Kirei.

Kirei: "It is a pleasure to meet you. My name is Kirei Kotamine and I will be one of the mages participating in the coming 4th Holy Grail War."

Regis: "I see. Please, continue with your conversation. Tokiomi, I can wait."

Tokiomi: "Of course."

After that, they continued to explain to Kirei about the whole Holy Grail War and such. Later on, Kirei Kotamine consented to it and is now walking away from the building while Tokiomi, Risei, and Regis were at the balcony seeing the young Kirei walking.

Tokiomi: "I didn't expect for Kirei to consent to this."

Risei: "My son would jump through fire if the Holy Church will say so."

Tokiomi: "To be honest with you I am quite shocked. From his perceptive he is being drawn to a war he has nothing to do with it."

Regis: "It wouldn't be strange for some bloke to one day manage to get their hands on one of the stigmata."

Tokiomi: "Using your time magic again, I see. Tell me, Regis. Who is going to win in this war?"

Regis: "Now why would I do that to spoil in the fun? To be honest I didn't use my magic to see through time, even though it has been only three years since we last saw each other, I'm still not in full control with this magic."

Tokiomi: "Shame."

The three of them went down from the balcony and both Tokiomi and Regis are alone in the office talking to each other. Regis' butler named Alfred served them tea.

Regis: "Is there some sort of other businesses that you want to discuss aside from me being assigned as the Overseer?"

Tokiomi: "You have heard the Matou's inhuman arts, haven't you?"

Regis: "Yes, Kariya himself told me that himself when he was last seen back in Manchester."

Tokiomi: "...Sakura...My other daughter."

Regis: "What about her?"

Tokiomi: "Both of my daughters possess exceeding rare sorcery traits. Rin possessed all five elements while Sakura, though lacking all five, possessed Imaginary Numbers."

Regis: "I see."

Tokiomi: "I want Sakura to be a powerful mage and I don't want to hand her over to the Mage's Association. So I'm planning to hand her over to the Matou family."

Regis: "Are you insane?"

Tokiomi: "I would have given her to you but I didn't think you would respond."

Regis: "True, as our family never wants to do anything involving with the Mage's Association's business and the other families. But you could have sent me a letter."

Tokiomi: "Yes, I should have. I am going to hand her over to that insufferable old man when I return. Will you at least give her one of your miracles so she can survive?"

Regis: "You're asking a lot in this Tokiomi."

Tokiomi: "I know, and I am sorry but..."

Regis: "Very well then. Let's go back to Japan."

Tokiomi: "Thank you, old friend."

The three of them left Italy and went to Japan. The three of them arrived at the Tohsaka manor, there. Tokiomi was greeted by his two daughters.

Rin: "Papa! Welcome back!"

Sakura: "Welcome back, Papa."

Tokiomi: "Sakura, Rin! There you two are! Come to Papa."

Both of them ran towards Tokiomi while he knelt down to hug them. As the two sisters hug their father. When Rin notices Regis she holds her dad's hand tight.

Rin: "Papa, who is this?"

Tokiomi: "Ah, this is Regis Trevelyan. An old friend of mine."

Rin: "Does that mean he's a mage too?"

Tokiomi: "Yes, he is just here to visit Japan for a few days."

Sakura: "Hello, Mr. Regis."

Regis gives Sakura a head-pat.

Regis: "Hello to you too, Little one."

Sakura smiled and that made Regis feel guilty just leaving her in the hands of the Matou, After that. Regis left the manor from time to time to look around Fuyuki with Tokiomi and the rest of the family. Currently, they are in a park around the neighborhood.

Regis: "Well, Japan has been a lovely country."

Rin: "Uncle Regis, where do you live?"

Regis: "Oh? I live in the U.K."

Sakura: "Wow... I want to go there."

Rin: "Don't worry Sakura! We're going there one day!"

Sakura: "Right!"

Regis laughed and the two sisters looks at him confused.

Regis: "Both of you are like my sons."

Tokiomi: "Oh? So Zack already has a brother?"

Regis: "Well, he did have for a while now. I think he's the same age as Rin's."

Aoi: "What's his name?"

Regis: "My youngest son, Roy Trevelyan, and my older is Zack."

Tokiomi: "I see. Why don't we arrange for the two of them to marry each other?"

Sakura: "M-marriage...?"

Rin: "No! I don't want to marry! I'm going to become a strong mage!"

Both Regis and Tokiomi laughed at the sisters' antics. After a few days, it was already time to hand Sakura to the Matou family. But thanks to Regis' interference, Zouken didn't manage to throw Sakura into the worm pit, since each and every one of the worms all died on contact. Of course, Zouken was mad at this but he still doesn't want to let his secrets go, but while in his time of confusion he saw that Sakura was a perfect candidate for the next Holy Grail War without even using the crest worms.

Though he still throws her to the worms, some of them manage to go through her body but after seconds it died.

Zouken: "Interesting... Is this the power of the miracle that I heard about from the Trevelyan family?"

Regis flew back to the U.K to go home, when he arrived at the Trevelyan manor, he heard shouting. Regis went to the backyard and saw both of his sons, Zack and Roy.

Zack is ten years old and Roy is seven at this time. Both brothers were playing, when they heard their father's voice, they immediately stopped playing and went to hug their dad.

Roy: "Father!"

Zack: "Dad!"

Regis kneels down to hug his sons. Then a voice from inside the manor calls out Regis' name. He looks back to see his wife.

Regis: "Mercedes!"

Mercedes: "Regis!"

Both of them hug each other and both Zack and Roy went back to playing outside the manor. Regis explained about his visit to Japan and Mercedes understood why he did that. Then Roy entered the room where the two of them are.

Roy: "Father, do you have anything from overseas?"

Regis: "Hmm... Let me think..."

Roy: "Oh come on!"

Mercedes: "Roy, please don't shout."

Then Zack entered.

Zack: "I told you that dad doesn't have anything for us. Now pay up."

Roy: *pouts* "Fine..."

Regis: "Actually, I have something. For the two of you."

Roy: "Really?!"

Zack: "Wait, what?"

Regis gave them some stuff from both Japan and Italy and they were thankful for it. After that, Regis went out to go to the Clock Tower.

~~

In a church area of the mansion, Kiritsugu and Irisviel look at the item that the Mage's Association gave them. It was none other than the scabbard that was once used to sheathe the mighty Excalibur.

Kiritusgu: "I can't believe they managed to find the legendary Excalibur's scabbard and not a scratch on it. Is this thing really 15 hundred years old?"

Irisviel: "The object itself is a conceptual weapon, it doesn't last or degrade as any other objects do. Just like the legends surrounding its existence. It heals the owner's wounds and stops the aging process. Of course, it is only used for the original owner's mana."

Kiritsugu: "In other words, the master can use it in tandem with the user. To protect himself in the course of battle."

Irisviel: "That's just like you. What you're saying a tool is just a tool."

Kiritsugu: "That's right, I am. That goes for the Servant too."

Kiritsugu walks down from the altar as he speaks to Irisviel."

Kiritsugu: "No matter how famous the heroic spirit. When summoned as a Servant it is nothing but a tool for its Master. Anyone lets their fantasies get the better of them will never have the will to win this battle."

Irisviel: "And just the way you are that's why my grandfather decided for the scabbard to be perfect for you."

Kiritsugu: "What do you think?"

Irisviel: "Does his gift not satisfy you?"

Kiritsugu: "Of course it does. Jubstacheit did a good job. None of the other Masters has this kind of power."

Irisviel: "What's wrong with it then?"

Kiritsugu continues to explain to Irisviel about all these and that. Back in the U.K. Regis was called by the Mage's Association and the Church. He made his way towards the Clock Tower and then they gave him a helmet.

Regis: "What is this?"

Zeltrech: "This, Master Trevelyan is a helmet that was used by King Arthur himself."

Regis: "So, this is who my Servant is, huh? King Arthur."

Zeltrech: "Yes it is. Listen, boy. Even though you are only an Overseer. It doesn't restrict you to the church only. The Servant will be there for you and it will be of use to you IF for whatever reason one Master steps out the boundary."

Regis: "Then it is my job to quell it."

Zeltrech: "Yes. Before you leave, I have another thing to ask of."

Regis: "And that is?"

Zeltrech: "I'm going to need to transfer one of your sons to America."

Regis: "And I suppose you have a good reason for this?"

Zeltrech: "Of course. It is just fate."

Regis: "Fate, huh? We're talking about one of my sons, do you think that they'll be happy going to America split off from the other?"

Zeltrech: "Yes and sadly I couldn't do much. Both of your sons are dangerous when they get serious with the whole magic thing. I'd like to move one of them to America in another branch."

Regis: "Fine then. What about the other one?"

Zeltrech: "Take one with you to Japan. Let him see what the Holy Grail War is and maybe just maybe be a part of it."

Regis: "I don't like exposing my son to danger, but fine."

Regis went back to his home and explained a lot of things to his family. Of course, Zack didn't like the idea of going to America alone and then Mercedes then tells him that she will go with him while Roy is going with Regis to Japan.

The two brothers shared one last hug before they can play and fight again.

Zack: "Don't be a crybaby when you can't see me again, huh? Little bro?"

Roy: "Oh shut up! I'm going to surpass you one day Zack!"

Zack: "Nah! You'll never surpass me!"

Roy: "Watch me! Right Father?"

Regis: "If you work hard then one day you will."

The family said their last goodbyes for the time being and both Zack and Mercedes went to America while Regis and Roy went to Japan.

It took them three to five hours to go to Japan, after that. Both Regis and Roy went to the church in Fuyuki. When they arrived, they already saw the priest there with the magic circles and such ready for the summoning.

Priest: "Sir Trevelyan, the summoning is now ready."

Regis: "I see."

Regis then placed the helmet in the middle of the magic circle and it started glowing, Roy looks from behind the pews not knowing what the heck is going on.

Regis: "Oh hear me! The Servant I call upon you..."

The whole church started shaking after Regis poured some of his magic into the magic circle. Then the lights started glowing much brighter.

Regis: "Hear me, Oh great King of ages past! I call upon you now. Hear my summons!"

The light brightens up and then it died down, then in the magic circle was none other than the Lancer servant, the armor made out of the finest materials during that time, and not to mention that the thing the Servant wields was none other than the lance, Rhongomyniad.

Lancer: "I have answered your calls, I am the Lancer Servant. My name is Artoria Pendragon."

Regis: "Huh? Hmm... Are in ways related to King Arthur?"

Artoria: "I am King Arthur."

Regis/Priest: "N-No way!"

Roy: "Wow... so cool!"

Roy literally started checking out Artoria's armor which made the King of Knights a bit embarrassed but is happy that someone still admires her.

Roy: "Father, is this the Servant? She looks like some kind of King."

Regis: *ahem* "Sorry about my son."

Artoria: "It is quite alright."

Regis: "Roy, this is my Servant but don't treat her like some kind of servant."

Roy: "Huh? Father, I don't understand."

Regis chuckled and just gives Roy a head-pat.

Regis: "Don't worry about it. Just treat her with respect."

Roy: "Father, why is your Servant beautiful?"

When Artoria heard that, she blushed a bit but she calmed down to look at her Master and his son, though there was a bit of jealousy in their relationship.

Regis: "If you don't mind me calling you by the same class name as before. Even though we're not fully part of the Holy Grail War."

Artoria: "Yes, I was informed from the throne of heroes and the Holy Grail. We will not fight the other Servants in the war but to keep order. Though I have to wonder why the Holy Grail didn't summon a Ruler class instead."

Regis: "There are things in the Holy Grail we still don't understand much, but regardless. Let's go."

Artoria: "To where Master?"

Regis: *yawn* "To the hotel we're staying. It was a long ride coming here."

Roy: "I'm not tired! I can still wake up."

Regis: "Make sure to say that without you trying to keep your eyes open."

Roy then fell asleep and Regis just laughed it off, he lifts Roy up and went to the limo where Alfred was there waiting for them.

Alfred: "I assume that you already finished the things you did there, Master Regis?"

Regis: "Yes, this is my Servant, Lancer."

Alfred: "It is a pleasure, Ms. Lancer. My name is Alfred."

Artoria: "It is a pleasure to you too, Alfred."

Regis: "Hmm... Lancer, would it be difficult to change your clothing? I don't think it's wise to wear armor to a public place."

Artoria: "I see, what will I wear then?"

Alfred then hands her a uniform and Artoria just accepted it and went back inside to change, after a few minutes, she came back out wearing a black suit.

Roy: "Whoa... She looks like James Bond..."

Regis: "I hope that the suit doesn't hinder your breathing."

Artoria: "I am quite alright."

The next day marks the start of the Holy Grail War. Regis himself oversees the whole campaign. They still didn't make any moves yet even still, Regis kept his vigilance. As for Roy, he and Artoria were having a spar, using wooden swords.

Artoria: "Young Master, please concentrate, you can't surpass your family if you are distracted so easily."

Roy: "Y-yeah!"

Both of them swing their stick swords at each other, Artoria had grace in her swings while Roy's were just wildly hitting her while being parried. As the Regis was waiting, he was informed that there was already one who sought refuge in the church.

Regis: "I see..." *looks at Lancer* "Lancer, I will be going to the church to meet up with the Master who is now under refuge in the church."

Artoria: "Then I will accompany you."

Regis: "That won't be necessary. Keep watch on my son for the time being."

Artoria: "Very well."

Regis: "Roy, I hope that you will listen to Ms. Lancer."

Roy: "Yeah... I will..."

Regis: "Good."

Regis left with Alfred being the driver again, he went to the church and saw that the person was none other than Kirei Kotamine.

At the airport, Irisiviel can be seen going outside the plane and behind her was Artoria (Saber) wearing the same style of suit same as Artoria (Lancer).

Irisviel: "Oh my, so this is where Kiritsugu was born? Wow, Saber. How did you enjoy your adventures in the sky?"

Saber: "It was really nothing to speak of. It was far simpler than I anticipated.'

Irisviel: "Well, I suppose flying is nothing special to a hero, right?"

Saber: "No, that's not it."

Saber explained to Irisviel about the materialization of Servants, them being given knowledge about the whole thing in the modern world. She, Irisviel, and a homunculus being behind them following her mistress. Lots of people were staring at them especially at the other homunculi.

They later arrived at the location and Saber went out of the car first and went to Irisviel's door to and offered her hand to her.

Saber: "It is a knight's duty to serve his escort. I shall do my very best. Come with me."

She took her black glove and Irisviel accepted it and the two of them went out.

In another location, Kiritsugu knocked at the door 703 and then someone opened the door but it was still locked to see it was Kiritsugu so Maiya Hisau full opened the door and looked around to see if there was someone looking at them

Maiya: "The equipment you requested arrived a little while ago Madam Irisviel and Saber have just arrived in Fuyuki as well. All the other Masters will assume that she is Saber's master and act accordingly."

Kiritsugu: "Understood."

Maiya: "There was an incident at the Tohsaka estate. I recorded this footage."

She showed Kiritsugu about the whole thing, it was a Servant being under attack by another Servant from the sky or something similar.

Kiritsugu: "What's your analysis on this?"

Maiya: "It seems too good to be true. There seems to be very little time for Assassin's infiltration and Tohsaka's Servant attack. Assassin has a skill that masks his presence making it improbably that he was detected in advance. It is my opinion that Tohsaka was expecting an intruder."

Kiritsugu: "In a battle among Servants learning their identities is quite critical. Why would Tohsaka expose his Servant like he did?"

Maiya: "He must have a good reason. I suppose he had to."

Kiritsugu nods as his response and looks at his weapons.

Kiritsugu: "Tell me, what became of Assassin's Master?"

Maiya: "He took refuge at the church last night. The Overseer declared him that he is under his protection. Assassin's Master is Kirei Kotamine."

Kiritsugu: "Maiya, send a familiar to watch at the Fuyuki church."

Maiya: "Are you certain of that? Masters are forbidden to take action in the neutral zone. That's been established around the church. "

Kiritsugu: "Place it just far enough away as the priest won't be able to spy it."

Maiya: "There is a slight problem in that regard."

Kiritsugu: "What do you mean?"

Maiya: "The Overseer was not a priest but the Head of the Trevelyan family."

Kiritsugu: "You're serious?"

Maiya: "Yes."

Kiritsugu was a bit worried but he still went on his plan and checked with his guns and Maiya kissing him.

While that happens, both Saber and Irisviel were looking over the nighttime sea. the cold air kisses Irisviel's skin and her hair dance at the wind's tune.

Irisviel: "It's wonderful. Almost looks like a mirror that reflects the night sky."

After that, Irisviel was already playing at the water while Saber just looks at her, guarding her like some kind of bodyguard.

Irisviel: "It's fine to walk around a strange and wondrous new town while accompanied by a gallant gentleman."

Saber: "Did I really make a true gentlemen escort?"

Irisviel: "You were absolutely perfect, Saber. You really are the most wonderful knight a girl could ever hope for."

Saber: "You honor me."

She then bows down.

Saber: "Your highness."

It was quiet until Irisviel spoke again.

Irisviel: "Saber, do you like the sea?"

Saber: "I suppose. I don't really know. In my country and way back my time the sea was a battlefield from barbarians from the mainland."

As Saber told Irisviel about the times when she was alive both of them had a heart-to-heart talk then out of nowhere, Saber sensed a Servant nearby.

Irisviel: "What's wrong, Saber?"

Saber: "A Servant."
