Just a disclaimer, this story will break multiple things that are canon, and has multiple head canons, In the fate series, as this goes from a Grail war like the one in Zero, into the events of Grand Order, so during the Grail war the master will get multiple servants. Also, the Masters and some servants in the war will either be OCs or characters taken from other sources, and if they are taken from other sources I will state where they are from. Lastly, this will be a harem, with plans for a minimum of 5 servants planned as of now, but possibility of a sixth, so if you don't like harems then just don't read this, simple as that. Anyways, here's the chapter.

"So Shiro, you have the catalyst right?" Iris, my sister, asked me.

"Yeah, we should get to the castle soon, and if it truly is part of his armor, than this Grail is as good as ours." I said while looking down at the rugged spiral on the back of my right hand.

"Lets just hope we're not wrong in this, I don't like the air in this place."

"What, don't like having fresh air for once, it's Better than being cooped up in Osaka."

"No, it's not that. It's just quiet, there's not much magical residue here."

"Mhm." We reached the wall next to the castle that was rumored to be the legendary Camelot. "here." I boosted my sister over the wall, then jumped after.

"Right. Shiro, get the catalyst, I'll set up the circle." She turned and started creating the circle.

I started summoning my mana into my hand, and reached into the empty pocket of space that I stored the catalyst in. Pulling my arm away, I held what should have been a piece of armor from one of the knights of the round table, the strongest heroic spirits in Britain's history. "Shiro, it's ready."

I walked over to where my sister was and placed the chunk of metal in the middle. "Silver and Iron to the origin. Gem and the archduke of contracts to the cornerstone. The ancestor is my great master Shirayuki. The alighted wind becomes a wall. The gates in the four directions close, coming from the crown, the three-forked road that leads to the kingdom circulate." I paused to take a breath. "Heed my words. My will creates your body, and your sword creates my destiny. If you heed the grail's call, and obey my will and reason, Then answer my summoning! I hereby swear that I shall be all the good in the world, that I shall defeat all the evil in the world. Seventh clad heaven and the great words of power, come forth from the circles of binding, guardian of the scales!"

When I finished those words, the circle started glowing and the wind started billowing faster around us. A bolt of red lightning struck the metal in the middle of the circle and a dust cloud appeared. When the dust started to clear, I could see someone in a suit of armor in the dust, with red lightning crackling around them. Then stepped out of the dust and stood proudly holding their sword, looking in my direction.

"Who are you, heroic spirit?"

They stabbed their sword in the ground, and their helmet moved away, revealing a woman with green eyes and blond hair pulled back in a ponytail. "I am Mordred, the one and true heir of Altria Pendragon." She grinned and focused her eyes on me. "So now I ask of you, are you my master."

"Yes, I am, although I was not aware that the knight of treachery was female."

Her eyes narrowed, and she appeared with her sword inches away from my throat. "Call me a woman again, and even those command seals of your can't save your life." There was anger prominent in her voice.

"Very well." I pushed the tip of her sword away from me. "So, I assume that you are saber?"

"Of course I am." Mordred gestured to Iris, "Who's that?"

"My sister, Iris. And I would prefer it if you were to call me Shiro over master."

"Hm. Alright then Shiro, I don't suppose you have a way for us to get to Japan."

"Yes. We will be taking a plane, although we will need to get you a suit."

Her expression went from on of excitement to confusion. "why do i need a suit, this should be fine, right?" her armor disappeared and she was left with red under armor.

"Because, that is the only way we will be allowed on the plane, if you want when we arrive back in Japan we can buy you a new set of clothes."

"Very well then Shiro, lead the way."

Timeskip. Next day in Osaka.

"Hey Master, Seconds!" Mordred raised her bowl up towards me.

"Go grab your own, you have working legs don't you." I remarked as I took another bite of the curry.

"Fine, fine." She stood and started filling her fourth bowl. "So where's your sister at?"

"Practicing magic probably. It's not my business what happens to her. Anyways, we should address this Mordred." I looked into her eyes when she took her seat. "What is it you seek from the grail."

She adopted a grin on her face, "When we win the grail, I'm going to go and pull that damned sword before father even gets a chance."

"So, you seek to pull the sword of selection. An interesting wish, though it is reasonable."

"What about you master. Why do you want the grail?"

"I don't have any wish, I just want to be the one who wins this war."

"Huh? You don't have a wish? What kind of bullshit is that, everyone has their desires."

"Not everyone, some people are just bored and want something to keep them entertained."

"I guess that ma-" She cut of as her head flicked to her right. "There's an enemy servant nearby, but it seems they are in the house."

I stood, and Mordred followed. "Lead the way, and be ready for a fight." She nodded and summoned her armor and her sword. We headed through the house and stopped at the basement. "They're down here." Mordred ripped the door open and continued. We reached the bottom of the basement, and saw Iris holding her stomach with a woman with short pale hair and golden eyes standing over here.

"Iris, the hell did you just do."

She gave me a bloody grin, "I did it, I summoned a servant. I can finally become a better mage than you."

"Iris, give me control over your servant. You're not fit to have one, you'll die within hours." I said, faking concern.

"No." Her hand started glowing, "By my command se-" I pulled a knife out of my pocket of space and stabbed her in the stomach.

"I wasn't asking. Either give me your servant, or I will take her from you by force. If you hurry I could keep you alive, make your choice." I pulled my hand away but left the knife in her. "Besides, it seems your servant could care less about you."

I saw her look up to me with hatred in her eyes. "By my three command seals. I order you to form a pact with my brother." I felt a wave of energy go off around me.

"Good." I took the knife out of her stomach. "Well, I guess I get to let you live now."

She was still glaring daggers at me, "Just kill me you bastard, I thought I could trust you."

I chuckled at that, "Really, haven't you learned anything, you can't trust anyone in this filthy world." I dragged the knife across her throat, killing her.

I stood and turned to the two servants behind me. "So then, you're supposed to be my new master."

I look to the one with pale hair. "Yes, I am." I held my right hand out, "So, you are to be my new servant, correct? Call me Shiro."

She smirked and grabbed my hand as my command seals glowed, and three more appeared next to the others. She let go of my arm when the command seals were formed. "I am Jeanne D'arc. The dragon witch, unholy maiden of Orleans. Avenger class."

"So, that class isn't just a rumor. Now, let's return upstairs, we we're in the middle of a meal before this… interruption." I started walking up the stairs of the basement and returning to the dining table, with Mordred going back to eating and Jeanne standing watching.

"So, Jeanne, what is your motivation for this war, what is it you wish for."

"Huh? What I want? Revenge. Revenge on that damned city and the bastard the burned me, after everything I did and dying for them, I'll make them all burn. I want to show them that their "God" doesn't care about them." She said with a snarl.

"So, you want revenge for being treated as a witch, reasonable."

She looked at me, "What about you, what do you want from this?"

"Something to pass the time, it does get boring around here, and this war will be quite the thrill."

"So you don't even have a reason to fight." She sneered at me, "Well, you need to prove yourself that you're willing to see this through to the end if you want my help."

"So, killing my sister to steal her servant wasn't enough proof?"

"Have your saber kill another servant, then I may help." She glared dangerously, "And if you even attempt to use a command seal, I won't hesitate to burn you, understand." Jeanne growled out the last bit.

"Of course. However, I assume you will be in spirit form until then?"

She got an angry look, "No, the one who summoned me was incompetent. I was not summoned to my full potential."

"Great, I knew she would screw everything up. Mordred, I assume you would prefer being in physical form, correct?"

She looked up room her empty bowl. "Yeah, I need to have my feet on the ground, otherwise i cant stay calm."

I sighed and stood, "Right, come with me, it's still early enough we can go get you two clothes today." I started walking upstairs and the two of them followed me as we headed into my sister's room. "Just, find some clothes that fit, there should be some. I'll be down stairs when you two are done." I turned and went back downstairs, and about five minutes later they both showed arrived downstairs, with Jeanne wearing a black tank-top with black shorts and Mordred wearing a White shirt with white shorts.

"Alright Master, where are we going exactly." Mordred asked while walking to the door.

"Mordred, I told you quit calling me Master, and for where were going, there's a clothes store close by." I opened the door and started walking, with them following. "So when we get there, just find what you want and I'll buy it. We will take the train to fuyuki tomorrow and talk to the one overseeing this Grail war." We walked in silence until reaching the clothing store, where I handed Mordred a wad of yen and let them go in alone.

I looked down at the seals on my hand which started to form the shape of a dragon. 'This could be because of Jeanne' I continued musing until I heard Mordred's voice behind me. "Yo, we're done." I turned to see Mordred with a white tube top, denim shorts with a belt, and a red jacket, along with a pair of black hiking boots. Jeanne on the other hand was wearing a short body hugging black dress with a zipper in the middle, and a dark blue jacket with black fur by her neck and at the end of her sleeves, paired with knee high leather boots.

"Well, now that that's taken care of, we should start heading towards fuyuki. Come, this way." I started leading them towards the train station, with Mordred's walking by my side and Jeanne following behind.
