The Holy Grail War had been going on for around 200 years, spanning over three wars before reaching its fourth. During the third war, the Einzberns, one of the oldest mage families and one of three families that had created the Holy Grail, not the actual one but a good copy, for this war, were frustrated. They had lost the previous two Holy Grail Wars. They were not going to lose this one. So they tried to manipulate the system to produce a servant that was unstoppable.

Angra Mainyu. What should have been the god of all evil in persian mythology. The Einzberns cheated their way into creating his new class: Avenger. They were so sure that he would give them victory. None could stop them. However, he was not what they were hoping for. For in life, the servant they summoned was just an ordinary man. An ordinary man tortured and forced to bear all the evils of the world because of a tribe's religious reasonings. For years, he was tortured until he came to accept his hatred and that of the evil of humanity.

Angra Mainyu, the Avenger class of the third war, was the first to die because of his weak nature. What they didn't know would happen is that the Grail became tainted from all the curses and woes forced onto Angra Mainyu. The Grail, corrupted by all of this, tried to make Angra Mainyu's existence and wish true. It tried to grant his wish of becoming the god of evil, but the third war didn't allow for that to happen.

So Angra Mainyu waited. He waited sixty years for the next war so that he could finally be granted his wish. All he needed was to wait for the servants to kill each other so he could gain their energy. It was so simple. The mages wanted to reach the Root of the world. To gain ultimate knowledge and power. Some others, more interesting others, came with wishes. He'd be sure that those wishes were granted, if not in the ways that they wanted. He was an evil god.

Yet he wasn't happy. Not now. He felt something was wrong. Someone had messed with the Grail. It couldn't be one of the mages. They weren't powerful enough to do that. No, it was something else. If he could, Angra would scowl. It was a god. One of the gods had messed with the Grail. He could feel it and that made him all the more angry. It was the gods and their insipid followers that had created him. Had tortured him and now they saw fit to ruin his chance at rebirth? At revenge? No, he would not allow it.

He needed someone of this Earth to preside over this war. Ruler would do. Rulers were a class onto themselves. They were powerful and born from heroes that had no wish for themselves. They would not want the Grail and would have command seal in place that could make any other servant do what they wanted. They watched over the wars in order to keep them going as planned and that the war didn't spill out and reveal magecraft to the world.

Angra didn't care about that last part, but a Ruler would do well here. He just needed to find one soon and he had a few candidates.

Avenger was used to cramped and rushed places. Sitting here in a civilian airplane filled with heavily armed personal was not something that was surprising. As a leader of an underground resistance, they had to go to many lengths in order to hide and strike at the enemy.

What was surprising was this whole situation. He had only been to Russia a few times as a child for diplomatic reasons. He never cared much for the country. Too cold and he didn't care for the nobility there. Well, he didn't care for any nobility rather. He didn't care about these Russians or their mission to revive an old regime. Communism, he had learned it had ruled under. He almost laughed. That had never taken off in his world and apparently it had failed here but on a spectacular level.

Still, he needed his wish. He wasn't going to let anyone get in his way.

After being summoned, he had done his best to learn about this world. Oh yes, the Holy Grail had put all that information inside his head. He didn't have to read, such as he was doing now. Yet that information wasn't acquired by himself and it was general information. Nothing overall specific. He may be a spirit but he wasn't a robot or library.

"Comfortable, Avenger?" His master spoke. He looked over to see Irina Spalko stare at him with a contented if not devious smile of her own as she sat on the opposite side of the plane. He idly looked at her Command Seals. Command Seals he had learned were a lot like his Geass but whereas he needed to look into someone's eyes to activate it, she could do it anywhere and she had three of them while he could only use it once on a specific person. It rankled him that someone had that much control over him but it was hypocritical to think so given his own powers. Didn't stop him however from thinking it.

"As comfortable as I can be," Avenger simply stated.

"If I may ask, how are you taking all of this?" Irina asked. "Being here in the flesh. Well, as much flesh as a servant can have really."

Avenger quirked an eyebrow, "It's… interesting. I feel much stronger than I ever was in my actual life. I also feel like I have access to abilities I didn't have before. It's daunting, but I will learn to cope. I always have."

Irina nodded, "I wouldn't expect anything less from my servant." There was a moment of silence between them, "So who are you exactly? I can already tell you aren't from the ancient era because of that pistol of yours. Seems rather modern."

Avenger smirked, which clearly unsettled a few nearby Russians. Not Irina however, "I am quite modern, Irina. As for who I really am, must you continue this foray? Does it really matter who I am?"

"I must know who my allies and enemies are," Irina spoke. "If I don't, how am I supposed to act in this upcoming conflict? I'd be charging in blind."

Avenger nodded, "True, but I am not of this world. Simply reading the history books can tell me that."

Irina blinked in surprise, "But the Grail only chooses those of history and legend. Those of this world."

"This war is apparently different," Avenger stated. "I was known as a prince of Britannia, or Emperor before my death. Britannia isn't a country here. At least, not as it was in my world."

"Emperor? Britannia?" Irina sighed. "Well it would seem that I have indeed summoned an unusual servant. I had hoped to bring in someone akin to a national Russian hero but alas that is not to be."

Avenger chuckled, "So it would seem. You will see my abilities soon enough, Irina. I can assure you, that they are more than enough to win this war."

"I will hold you to that, Avenger."

Joseph Field sighed as he looked down at his wallet idly. His grandfather had told him a lot about the Holy Grail War. Well, some of it. One of those was that it was going to take place in Japan so he had to head there. Which had cost a number of pretty pennies to get two tickets to Japan on a cruise liner. That also didn't account for all the apples and alcohol.

He idly looked at the Beast servant he had summoned. She was eating another apple with a bottle of alcohol between her legs. She was humming happily as she took it all in, "Ah yes, I can safely say that these apples are fit for a goddess. I thank you for bringing them to me."

"You're welcome," Joseph sighed. "You do know that at this rate, I'll be broke right?"

Beast smirked, "At this rate you'll have your wish and all will be right in the world." Her tail swished behind her happily, "Isn't that what this whole silly war is about? A wish?"

Joseph nodded and scratched his head, "I guess so. I mean, you are one of the seven-"

"I'm not," Beast cut him off. She narrowed his eyes at his confused expression. "Do you not know the seven classes?"

"My grandfather didn't get to explain a lot before he died," Joseph shrugged. "Why? Is it important to know?"

Beast just gaped at him, "Of course it is. The humans who designed this war, if you still want to call it that, created seven classes: Saber, Berserker, Archer, Assassin, Rider, Lancer, and Caster. I myself am outside of those classes and I suspect that there might be more. At least one another. Call it a hunch or whatever else that insipid Grail put in my head." She huffed, "To think it would have the gall to force a goddess to participate."

"So the war's broken?" Joseph asked.

Beast shrugged, "Who can tell? It wouldn't be surprising. This is an 'all knowing, wish granting' cup made by power hungry humans. Why wouldn't it fail?"

"Yet you still want it?"

"Absolutely," Beast nodded. "Only a goddess such as myself can get it to work correctly."

Joseph sighed and rubbed his forehead, "This whole thing is confusing and it hasn't even started yet."

"Do not worry about that, 'Master'." She chuckled at the title. "Your faithful goddess shall illuminate you on the situation when the need arises. I do so hope you keep up."

'This is going to be a long war,' Joseph inwardly sighed.

Tokiomi Tohsaka, head of the Tohsaka family. One of the oldest mage families and one of the three families that had started the war. He had spent his whole life preparing for the war. Preparing his spells, catalyst, and everything else. Nothing was left to chance and everything was supposed to go along perfectly.

Yet right then and there, as he stared at Servant Assassin, he couldn't help but feel anxious. "So you're telling me the truth? That is Assassin?"

Kirei nodded his head, "As far as I can tell. The ritual was performed as your instructions but it would seem that the Grail found for us a new and… unique servant."

Tokiomi hummed in thought, "This changes our plans considerably. I don't think we can employ the same tricks I had wished to do in the upcoming war." He idly stared at the bipedal fox, thinking about what he was supposed to do with her. He then felt something tap his shoulder and suppressed the urge to jump as he turned around, facing the fox. He looked back to where the fox was a moment ago to see the image disappear.

"I can assure you," Assassin spoke with a feminine voice. "I can do all you wish and more."

"Illusion magic?" Tokiomi rubbed his chin. "Now that could be useful. Perhaps all is not lost then. How intricate are these illusions?"

"I could mimic three legendary creatures perfectly," Zoroark stated. "None were the wiser."

"Legendary creatures?" Tokiomi quirked an eyebrow. "If that is the case, then Assassin. It is an honor to have you with us."

Assassin bowed her head, "As long as you don't try and shove me into a cage, I will do my best to fight with you humans."

It was at that moment another priest walked into the room. He was much older then the others, with long gray hair and a large cross around his neck. He was Risei Kotomine, father to Kirei and overseer of the fourth Holy Grail War. "I have important and unsettling news. The servants Avenger and Beast have been summoned."

Kirei and Tokiomi both stared at him in utter disbelief.

"How is that possible?" Tokiomi asked. "They aren't part of the seven. Has someone tried to cheat the system again?"

"It would appear so," Risei sighed. "I had wished to avoid seeing the bloodshed and destruction like the previous war, but with ten servants-"

"Ten?!" Tokiomi's eyes widened. "How do you know it to be ten? Maybe they were simply interchanged with two of the other classes."

"I would have thought so until Ruler told me otherwise," Risei stepped aside.

In stepped another older gentleman. He had a white beard and mustache yet seemed both younger and older then he looked. He was smooth skinned and caucasian, appearing to be in his mid-years yet his eyes spoke of an older and battle hardened fellow. He wore an American Confederate General uniform and had a saber on his hip. Ruler bowed, "I am the one that is known as Ruler. I was brought forth to oversee this rather strange war."

"It is great to see you, Ruler." Tokiomi sighed and took a seat. He was feeling a headache come its way to his head and he was sure it wouldn't be the last. "I take it your arrival really sets the stage for a cumbersome war ahead."

Ruler nodded, "Indeed. I can already sense that most of the servants of this war, as you see here, will not be of this world."

"Not of this world?" Kirei spoke up. "What are you talking about? Surely she is some sort of kitsune spirit."

"I am a pokemon," Assassin huffed. "Not this… kitsune you speak of." She almost seemed offended by the remark.

"My apologies, Assassin." Kirei bowed his head. "So does that apply to you as well or are you truly one of the Confederate Generals of the past?"

"I am indeed based on my Virginian counterpart," Ruler smiled. "I can also sense another spirit awaiting her summon that is also another of this world but I cannot say. The Grail only imparts some level of knowledge on the other servants and their summons."

"I take it you will, alongside Father Risei, make sure this war stays between us Masters, correct?" Tokiomi asked.

Ruler nodded, "I will do everything in my power to keep this war hidden and the innocent safe. That much I promise."

"Good," Tokiomi smiled. "Then let us wait for the rest of the pieces to fall into place before making our move."

So Assassin, Beast, Avenger, and Ruler have all shown their hands and made their appearances. Don't worry everyone. The next chapter will show the other summons. Artoria will still be staying the same since, well, she's one of the more iconic characters of this show and I don't think I could adequately change her. So we'll see what interesting adventures she'll get up to now.

I hope you all enjoyed this chapter and please leave a comment. They are very much appreciated and really do help me improve and know what you enjoyed. Until next time, have a good day.
