Prologue

AN:Fate Series/Naruto/and later High School DxD Crossover Story

"Such bugs fighting for a bigger piece that is so fun to watch… but playtime is over," A voice ringed through Church like temple from the Hanging Gardens of Babylon.

This caused all the Servants and two Rulers to look around to who talk to them all the sudden. Red Faction and most of the Black Faction of Servants looked or scene anything Servants or Mages leaking in the shadows, but soon found a man coming out of the shadows before them.

He was a young man with shadow like hair that moves with the air and deep dark blue eyes that shin with pure blood lust and death. He wore a black shirt, jacket, pants, combat boots and had silver chins running down his pants. His smirk showed lust, power, and darkness.

"Now you are all here it makes it easy for me to what's to come next," The Shadow man said as he reached for something in his jacket.

"What are you?" Ruler or Jeanne D'Arc asked, grabbing her flag spear and narrowed her eyes at the new comer.

He wasn't a Servant but for some reason he felt like one and others could read him. Shirou Kotomine, the Red Faction Ruler or by his real name, Amakusa Shirou Tokisada, couldn't scene the unknow man and show that was human with some ranks for some odd reason. The Servants in the room felt something dark within the man and a shadow was coming to where they were at for some reason. All the Servants' thoughts change about the man in front when he pulled something out and used.

The Shadow pulled a strange looking card to drop in front of him and said, "Authoritarian Personalism: Faceless Jet-black Sovereign."

As the man chatted, his card to work and it activated a powerful Magecraft onto Rulers and Servants all the sudden. A black void fills the room up and covered every inch of the place to start the magic. All the Servants and Rulers were affected by a powerful gravitational force that plunges down to the ground before man that started laughing like manic. The Servants and Ruler tried to fight back but failed and only incase the powerful onto them. It wasn't a physical in nature, but an attack of conceptual interference that is able to easily break through their defenses.

"What is this?" Rider of Red or Achilles asked as he felt weaker by the second as the gravity took affect on him.

"T-this is a strange Magecraft that effects Mages and evening Servants," Caster of Black or Avicebron answered through his breath and was getting more weaker like the other Servants.

Soon enough Authoritarian Personalism started to go off but the Rulers and Servants were still weak and had little mana within them to fight back or return to Spirit Form. The Shadow man walks towards the laid down Jeanne and smirked at her weak state.

"Ruler that holds the Command Spells that I need… fits perfect to my plans," The Shadow man said as he reached forwards with his left hand to grab all the Command Spells off from Jeanne's back.

The Command Spells appeared, shining blight red as the man was getting close and Ruler had no way to fight back to stop this man. The Servants and other Ruler could see what was going on and had no energy to fight but felt some of their mana returning to them slowly.

Then all the sudden and out of nowhere, a blue energy line comes out of nowhere and towards the Shadow man's left arm, causing him to jump out of the way and got everyone to look at who swung a power sword towards the unknown man to find another stranger.

The new comer was a tall young man with dull silver short hair and aura blue sited eyes like a dragon. He wore a black armor with silver armor that bears that look close to a dragon and had a face guard that looks like a dragon as well. A broadsword on his back that look closely to what Saber of Black wielded, a golden hilt sword on his left hip in a black sheath and carried a duel wielding sword with one end longer than other one and was covered in blue mana.

What was evening a bigger surprise when the Servants read dragon knight to only find that he has a ranking like a servant but was human and mage. It should be impossible but if one remembered right that Sieg, transformed into Saber of Black to battle against Saber of Red. But this was different and many wonders who this man was.

Jeanne and Shirou looked at the new comer and saw his rank, class, and what Heroic Spirit he was. The young man shared all the ranks and class of two Saber Class Servant but was more surprising that he was a Saber with Siegfried and Sigurd in him.

"You again!" The Shadow man shouted in pure rage and glared.

"Yes, and go back to the shadows, Menma," The Dragon Knight responded with his eyes narrowed and pointed his blade at the black-haired man.

The Shadow man or Menma glowed at the knight in front of him and soon show that the Servants and Rulers were getting their full strength back, meaning he was out of time. He can't fight all of them at once and the showing of his hated enemy made it worse for him. He can wait and needs to make a quick escape.

"Another time…failure," Menma said with his eyes narrowed and started to transform into a pure black shadow, disappearing before everyone.

The Dragon Knight sighed as he placed his dual bladed sword on his back and walked towards the card on the floor. He placed his right hand on it before activating his mana into his hand and destroyed the card before him, leaving behind ashes and shook his hand clean off.

Soon the Servants and Rulers got up on their feet as their mana was restore and wonder what this new unknow Servant before. The Dragon Knight looked at the group and titled his head to the side in question.

"Is something on my face?" The Knight asked, pointing at his face with his right pointer finger.

"Really?" Everyone thoughts were and most of them shook their heads in no which caused the knight to sigh in relief.

Before anyone of the Servants or Rulers could ask any question, a beep noise was heard, and it came from the right wrist on the knight's. The silver haired man raised his wrist up and saw blue light blinking before him, causing to hum very quietly and press the button to open the channel. Soon a blue hologram of man appeared before and to everyone could tell it was a long commutation by magecraft.

"Doctor Romani I have arrived but Menma has beat me here first again and he to use one his self-made Noble Phantoms on the Red Faction, Black Faction, and Rulers, but I took care of that and destroyed the card for one least card to worry about. My Servants and I will follow him after a meeting with them," The Knight informed the hologram of Romani.

"Hmm, I see. Keep an eye out for Menma and be careful, Alex. We still don't know how he can teleport to one era to another or the power he has. If you fight him again, don't do it alone," Ramani said after thinking some thoughts over.

"I might have to fight him alone when the time comes but I will keep it in mind, Doctor Romani," The Knight or Alex replied, ending the commutation and looked back to the group.

Alex could that the group wanted some answers as what was going and understands that but not now.

"Ruler that watches over the Great Holy Grail War and Ruler of the Red Faction, I ask for a ceasefire and the Grail War to be put on hold. I have some things that consensus everyone and the Greater Grail's safety. I will be happy to answer to what is going and a meeting should be held tomorrow at any locations you wish to pick out," Alex said in a calm tone of voice.

Servants of Red and Black could see no signs or harm what so ever but spoke and his eyes had honest within them. Evening he was new and helped them, they have this feeling that they can trust him for some odd reason. Jeanne and Shirou could feeling the trust and honest like the other Servants. They can agree on a ceasefire and have a meeting to what was going on. It won't anyone to stop the Grail War for a little meeting.

Jeanne nodded her head in answered and said, "Very well, I agree with the ceasefire and have the Greater Holy Grail War put on hold for the time being. A meeting will be held in the fields by the Black Faction location. Do you agree Amakusa Shirou Tokisada?"

"I agree with putting the Grail War on hold and the ceasefire. That should give me time to explain to the Red Faction of a few things," Shirou agreed with a nod and wanted to talk to his new Servants of the new deployments of him being their new master.

The Red Servants seem to agree with it, but Lancer, Rider and Archer were more focus on getting answers on what happen to their old master first. The would like some answers about the masters and what was going on.

Archer and Caster of Black were quiet for a moment, talking to their masters through spirit thought about what happen and do they agree with the ceasefire. Soon enough one of them spoke.

"My master agrees with the ceasefire. She will allow the Red Faction to be there at the meeting," Archer or Chiron responded as he put his bow away from now.

Avicebron nodded his head in agreement before going into spirit form and Chiron followed behind for both them to return to their masters. Alex looked back at Jeanne, Shirou and the Red Servants before nodding his head and started to teleport within a blue magic circle, leaving for the night Ruler left the Gardens with no one harm come to her and made her towards the Black Faction castle to talk about the new appearances and put the Grail War on hold.

Time Skip

After a day went by, the sun was shining down the battle field that held the first battle and will held more upcoming battles that is to come. The Black Faction agreed with the ceasefire and have the meeting set up in the fields. Fiore Forvedge Yggdmillennia had agreed to meet with the new comer name Alex with her Archer Servant by her side. The others are watching from golem bird view that shows a mana screen at their side.

AN: Berserker of Black is still alive by the way. Just throwing that out.

Jeanne agreed on meeting with knight and wonder many things about him. Like she didn't show any vison of the Shadow man, Menma, and the Dragon Knight, Alex. It makes more questions, but she has a feeling that all of them will be answered soon enough.

The Red Faction have fixed the new master problem out, being fine with the ceasefire and meeting with the knight. They also allowed Saber of Red and her master to be part on what was going on. Shirou and his Assassin Class Servant, Semiramis, were going to the meeting while the others waited at the Gardens and watched from mana screen for the time being.

Soon enough they made towards the middle of the field to see the Dragon Knight in normal cloths, watching the sun rise with a calm and warm smile on his face. He wore grey shirt, black fingerless gloves, a blue scarf wrap around his neck, black jeans, shoes, and a grey coat with black strips on the sides of it.

Alex then started to notice the guest were here and turn his attention towards them.

"Welcome everyone to the met that I will explain everything to you all," Alex greeted with his smile still on his face.

Jeanne and Shirou could tell now that he was human and could only guest one thing on how he become a Heroic Spirit but will hold that thought for now. Semiramis and Chiron scene no threat from the knight and could relax for the time being for their master's sake.

"I believe introductions are in order before I explain everything. I will start first, my name is Alexander von Einzbern, but please call me Alex," Alex introduced himself with a smile on his face and took a small bow.

Now this surprised the group in the met and are watching it on what his name was. The Einzbern had all died out during the Third Holy Grail Way and haven't been heard since then. Jeanne hasn't met Einzbern, but with Grail information has helped her once more. She knows that the Einzbern family and two others helped created the Holy Grail War and wonders about the man in front of her. Shirou was taken back on meeting another Einzbern in front of him. He hasn't seen one since the Grail War he fought in, but he shook his head and put their past thoughts aside of him. He could tell that Alex was indeed Einzbern, half from the looks of it.

Alex smiled at them and said, "I expected that reaction. I was blood adopted by the Einzbern family and I will explain that part soon enough, but first I like to know your names first."

"Of course, my name is Fiore Forvedge Yggdmillennia, head to the Yggdmillennia clan and Master of Archer, who you already met," Fiore greeted with a smile as she used her right hand to point at her Servant behind her.

Chiron nodded his head with a smile on his face in respond.

"My name is Amakusa Shirou Tokisada, Ruler of the Red Faction and this is one my servants, Assassin," Shirou greeted himself and his Servant with kind smile on his face and eyes close.

"Hello, Alex was it?" Semiramis said with a teasing smirk on her face.

Alex just smirked back and said, "Yes and are you Empress by any chance?"

"Maybe what get it away?" Semiramis asked as she placed her right hand on her chin and still had her smile on.

Alex shrugged his shoulders before smiling and said, "I have a Servant that is well known through the Babylonia period and your beautiful Gardens reminds me so much of Babylon. I have to say you done a great time on building the Hanging Gardens of Babylon."

Semiramis smiled at the comment and was little taken back of knight's not looking at her in any lustful matter but looking at her a good way that shows kindness and respect.

"Thank you for the comment, but I believe we are getting off topic," Semiramis said, making a good point.

"Good point," Alex added with small node and turn his attention to Ruler that was waiting for her turn.

"My name is Jeanne D'Arc, Ruler of the Greater Holy Grail Way. Its nice to met you Alex," Jeanne greeted with kind smile on her face and was welcome back when Alex smiled back at her.

"Jeanne, hmm, nice to met you all. Now it's time I explain what happen last night and where do I come from," Alex said, getting himself ready to explain everything.

Once the group in front was ready for him, Alex got himself and soon started from the begin.

"From another world and another time line that in voids the Third Holy Grail. Within that Grail War has two different outcomes that affect the whole Grail Wars which was caused by the Einzbern family. The Einzberns in this world summons the Ruler Class Servant in hops on topping up the other masters and their servants, but that failed and Darnic over power the whole Grail War with an army at his side. That is your world and now my world had a different outcome that lead to me on being here.

Within the Third Holy Grail War, the Einzbern family summons the Avenger Class Servant which was weak and first to die in the Grail. However, something happened that lead to the creation of a great evil gaining more power," Alex explained the first part and took a break to gather his thoughts and allow the group to gain the information or ask any questions.

"What great evil?" Fiore asked.

Alex stood quiet for a second, not wanting to say it but spoked, "All the World's Evil, Angra Mainyu."

The Rulers and Servants eyes widened in pure tremor and shock on what the Einzberns were thinking in Alex's world.

"What happen when the Avenger was killed?" Shirou asked with his eyes narrowed a little, having the feeling that he was not going to like the answered.

"He was trapped in the wish-granting spiritual Holy Grail and his influence tainted the Grail system, because he was turn into a real daemon who would be the source of All the World's Evil and he caused the changes to summon Servants within the next two Grail Wars, the Fourth and Fifth Holy Grail War. My parents fought in the Fourth with a Saber Class Servant by their sides and found out about the All the World's Evil during the mid-end of the Grail War," Alex answered and informed more to the group.

"I'm guessing when they found out about Angra's tainting the Grail. They used a Command Spell to destroy the Grail," Shirou said, having an idea on what come and what he will do if met this Avenger Class Servant.

"Could that be possible?" Fiore asked, not seeing who a Servant could destroyed the Grail from what she saw.

"It could but it's a long shot. Only a powerful Noble Phantom can destroy something powerful that contains evil within, but the outcome will come out if that happens," Jeanne replied.

"Quite right, but that would be hard to do since Mages and Servants will be blinded by their own wish to see the truth," Shirou agreed and make a good point out.

Alex nodded his head and said, "True, most will be blind by their own wish, but my parents went the All the World's Evil and that creature of darkness wanted to unleash his vison of the Third True Magic, Heaven's Feel onto the world but father stopped it which he failed to destroy the Grail and gain a deadly curse because of that. It took years later before he become to his own death but was happy that he had family and died with no regrets."

Jeanne, Chiron, Shirou, and Semiramis could see sadness in Alex's eyes but he changed with a smile and not be sad for his old man's sake. Fiore saw it as well and was happy for the silver haired man to change it quickly for his father sake to not get sad for his death and be happy with his life. That cause another question, how much has he gone through?

"After the Fourth Holy War and next Fifth started ten years later with my brother and I joining into Grail War to end all Grail Wars once and for all. He summoned a Saber Class Servant and I saved a Caster to become my Servant by her chose. I won't go in depth with the war I been through, a story for another time, but I will tell what happen afterwards and it voids with me being here.

Once the Grail War was destroyed and Angra Mainyu was no more. I joined the Clock Tower in London and become one of the top students of my classes. It bought the attention of a group that was training young minds to help history events and fix time eras. Within a few months later, a massive change happens to many time eras and caused the whole world to go dark before are very eyes. It was then I found out that a Black Shadow was the embodiment of All the World's Evil and was changing every era to gain more power. On that day, the Grand Order was born, and we fixed many and different time eras to this very day," Alex informed.

Jeanne, Shirou, and the Servants that were watching or in the meeting could understand two things that Alex was sent here. To fix the time lines from Menma, the Black Shadow that holds All the World's Evil within him and make sure the Greater Grail is safe to avoid another Grail hosting any dark creatures. To some it might be crazy to think about other worlds, but a center old troll prove has one of the True Magics that helps him travel to different world and troll people to his enjoyment.

Fiore and the Masters of Black might think it was crazy to think about other worlds, but the head Mage can tell that Alex was telling the truth and could trust him. She hopes that her brother and other masters could trust the silver haired man.

"What do you have in mind on stopping Menma from gaining the Greater Grail?" Shirou asked.

"Simple, the Red Faction and Black Faction must agree on an alliance to stop Menma and his Shadow Faction from gaining the Grail. My own Faction of Servants and myself will help against the Black Shadow," Alex replied, offering his hand out to Ruler in friendship and alliance.

Jeanne thought careful on the offer for two Factions of Servants to work as one and have another group of Servants joining the battle against the Black Shadow. She could understand the safety for the Grail and for some reason trust Alex very much. She wonders what the two Faction will think of the allying with each other and another Faction.

Shirou placed his right hand on his chin, thinking deeply and the idea of allying with two other Factions of Servants. His wish was still in his mind and thought deeply of what Alex told him. He wants to fulfil his wish for humanity sake, but with the threat of All the World's Evil and what damaged it can cause to the Grail made him think of the alliance. If he wanted to help humanity, then he must stop the evil that will harm humanity and his mind was now made up.

Fiore had made her mind up on the alliance and it's seem the best way to stop the Black Shadow for good. Having three Factions backing each other could be the way to tip the war into their favor and could make it harder for Menma to get the Greater Grail. After all it is the safes places now and who in their right will go into places that has a Faction on guard.

Chiron and Semiramis waited for their master and the Ruler to give Alex their answered, but they didn't have to wait for long when one took his hand.

Jeanne had finally taken Alex's hand and said, "I agree with the alliance and that this Grail War will have three Factions against one until the very end and the Greater Grail is safe, Alex."

Alex smiled with a nod to his head and looked at Shirou and Fiore for their answered.

"I'm willing to work along side the Red Faction and yours, Alex, as long that Shirou agrees to the alliance and keep the Greater Grail in the Hanging Gardens," Fiore replied, looking at the priest for his response.

"I'm agree with the alliance and to keep the Greater Grail in the Gardens," Shirou replied as he took his hand out to shake Alex's for sign of trust and agreeing with the alliance.

Alex smiled happily and shook the priest's hand. After he was done, the young man know that this was the first step and had many more steps to come with battles against the Black Shadow, Menma and his Shadow Faction.

"I will get my Servants to meet you all in the Black Faction for introductions and later met the Red Faction for the same thing. See you all very soon," Alex said with smile and bow before teleporting with a blue magic circle to the location he kept his Servants at for the time being.

As the group watched Alex take his leave and they thought about what Servants he had with him. If they are someone from their own Faction Servant's past, being bad could have a bad outcome and a good could lead to something great. They can't say for sure but will wait for the silver haired man's return with his Faction of Servants for the introduction. They have a feeling that the Great Holy Grail War is about to get even more bigger from what's to come ahead of them.
