3rd Person Pov

The Holy Grail War, a contest, found by the Einzbern, Matou, and Tohsaka families centuries ago, in which seven mages summon seven Heroic Spirits to compete and obtain the power of the "Holy Grail", which grants a wish to each member of the winning duo. However, after the disaster in Fuyuki, there was a change in history. An 8th master rose up, he had more mana than everyone else, but this master was able to summon not one, but multiple servants due to his hight reserve of mana. Now, this master was said to be gone forever. Until now that is. In England, a 15 Year old boy was invited to a school of mage craft. His name wasn't known by many but one, Sieg or what his servants call him, Y/N

You: This place is so big, how am I supposed to find anything in this place?

Y/N sees a boy, not too much of his age carrying many books as he tries to talk to him

You: Excuse me?

???: Hm?

You: Could you help me find this room?

The boy looks at the place where Y/N needed to go and tells him that he was going there too

Flat: To think that Lord El-Melloi II would ask a foreign student from Japan to come here. Oh right, I forgot to introduce myself, I am Flat Escardos, and you?

You: Y/N Emiya Von Einzbern

Flat: Emiya?! And Einzbern too?! You're a child of both founding families of the Holy Grail War?! This is so exciting!! Come on, he's waiting for you!

Flat opens the door and let's Y/N inside

???: I've been expecting you, Y/N.

You: Wait... Waver Velvet?

Waver: It's no surprise you'd recognise me, even after a few years have passed after the war in Fuyuki and my appearance had changed, Y/N. However, I now go by the name of Lord El Melloi II

Flat: You both know each other?

You: Yeah, we both fought in the same Holy Grail War.

Flat: Amazing!

Y/N and Flat sits down as Waver tells about the War in Fuyuki. Apparently, the war system was proliferated and became universal and now, it's done all over the world.

Flat: I wanna participate-

Flat was flicked away with Waver's finger

Waver: Even if you cry, I won't allow you to participate

Flat: I know! So is Shishigou and Y/N here to join a subspecific Holy Grail War too?

Waver: No, you're incorrect. We're not having them participate in a subspecific holy grail war. Y/N is here to investigate one of my students

You: She goes by Gray, you know them?

Flat: Nope, not at all.

Waver: According to news, the Greater Grail has been declared recently, the Yggdmillenia family of mages, in charge of Romania, has declared ownership of the grail itself, so Y/N is here to take care of that as well

Flat: Amazing! Just like in the movies!

Waver: Unlike most families, this family doesn't pass their mage craft to just one child, but has a peculiar disposition to seek comrades shallow and wide. Quantity over quality, their concept on family is different from mages who try to pass on as many Magical Circuits as possible to strengthen the crests. If they mobilise, mages out there will try to join them.

Flat: Why would they do such a thing?

You: An association, they want their fireworks to be grand, to put it. The are second rated at best with some being able to become First rated mages like Darnic. There are even some in the clock tower as of now.

Waver: I expected that too. They have probably summoned their first servant too.

You: In other words, you sent me to help in this war, most likely because of my subsequent amount of mana, correct?

Waver: You're correct.

You: I see, then I won't stand down without a fight.

Waver: However, this won't be any normal war, we are on the Red while the Yggdmillenia are the Black, meaning a 7v7 brawl.

Flat: One... two... 14 in total?!

Waver: Yes.

Flat: Wait, then Y/N's role? It's because we have 7 members already

Waver: The 8th member. Unlike most master who can only summon one servant, Y/N here is capable of using more than one servant

Flat: Amazing!! How many??

You: No comment. Oh yeah, who's the director?

Waver: A preist named Shirou Kotomine

You: (Kotomine?!?!) I-I see... Is this all?

Waver: Yes, please follow me. Flat, go back home

Flat: Hai!

You: So that's Gray?

Waver: Yes, Gray comes from the Blackmore Cemetery in Wales, America. The clan of the village there aimed to create a being capable of handling the Holy Lance that had been passed down for generations. In other words, their purpose was to revive King Arthur, in flesh and spirit. However, their attempts had thus far been continuous failures, and the ritual had been relegated to folktales and tradition.

You: Rhongomyniad?

Waver: Correct. Gray was to be the flesh of King Arthur. When she was born, her facial features vaguely resembled those of King Arthur, but ten years ago her body suddenly changed to that of King Arthur's. Losing her true face, she could no longer differentiate her own existence from that of King Arthur.

You: Such expectations already put on a child...

Waver: ... Gray, come here

Gray heard her name as she walks over to Waver as she covers her face with her cloak

Waver: This man will be taking care of you and the one who will be teaching you magecraft from now on, Y/N Emiya Von Einzbern, a friend of mine

Gray: I-I'm the Grave Keeper, Gray. I-I might trouble you in some aspects but please take care of me...!

You: Hey, how old are you?

Gray: ...15...

You: The same age as me huh? Alright then, I hope that we can be good friends, Gray.

Gray: T-Thank you...

Gray shakes Y/N's hand as they thank Waver before leaving for Y/N's temporary home

Jeanne: Welcome home, Y/N!

You: Hey, Jeanne. This Gray, the girl that Waver was talking about

Jeanne: Nice to meet you.

Gray: N-Nice to meet you...

Jeanne: Hm? Why not show your face? Everyone here in Y/N's place is friendly.

Gray: No, I'll keep it like this... I don't want anyone to see my face

Jeanne: I see. Oh well, I won't force you. Oh yeah, Y/N, Mordred says that soon, someone will summon her

You: I see. Well, we'll see who will be the one to wield the Round Table. I'm also expecting a second Mordred, hehe, that'll be funny

Mordred: Hah! In your dreams!

You: We'll see! If I guess correctly of a second Mordred, you're not eating for the next week!

Mordred: That's unfair!

You: Too bad, glutton, you're just like your father

Mordred: Come here!

Mordred chases Y/N around as Gray was stunned a little as Jeanne laughs a little

Jeanne: Expect to dee this everyday, Gray. Y/N may look scary at first... but, he's the sweetest boy I've ever met.

Gray: I see...

Time skip

It was night time as Y/N went outside to summon his next servant for the war

Musashi: I wonder who will be the next servant, I bet it'll be another female~

Tamamo: Fufu~ Of course, most of us are that gender so it's obvious what kind of gender he'll get

You: Oh come on! Heed my words. My words create your body, and your sword creates my destiny. If you Heed the Grail's call and obey my will and answer, then answer my summoning! I hereby swear that I'll be all the good in the world, that I shall defeat... all the evil in this world! Then let thine eyes be clouded with the fog of turmoil and chaos, thou who art trapped in a cage of madness, and I, the summoner, who holds thy chains. Seven Heaven Clad and the great words of power, come forth from the circle of bindings, Guardian of Scales!

Y/N declared the chant as the circle lit up, showing the newest servant

Ushiwakamaru: I have been called upon, Ushiwakamaru, Rider Class. Honoring the full devotion as a Samurai, I will do my utmost best!

Musashi: Ah! Ushi-Chan!

Ushiwakamaru: Musashi! Tamamo too?! You girls have been summoned by the same master?!

Tamamo: Of course. This is Y/N, our master

Ushiwakamaru: I see! Nice to meet you, my Lord!

You: My... Lord?

Musashi: We usually call our master, lord. Now if you'd excuse us, you and Ushi-Chan will talk!

You: Eh?! Okay then...

Ushiwakamaru: Alright then. So, what do you wanna talk about?

You: Let's see... ah, your legend! The Legend of Ushiwakamaru!

Ushiwakamaru: You know about me?

You: Of course, it's as popular as Gojyo Great Bridge, a nursery rhyme

Ushiwakamaru: Stories... about me, I didn't think people would familiarise themselves about me! I had been fighting for my whole life, it was a feeling that I wanted to help others, to be someone's assistance. However, such logic can't be understood by anyone

You: Your will has resonated in many people's hearts. I mean, your story was used multiple times over thousands of years! And I can see why you're fighting too

Ushiwakamaru: Eh?

You: I don't want anyone else than myself to cry. If possible, I want to stop those tears

Ushiwakamaru: Yes.. yes that's it! That's precisely it, Lord Y/N! I'm so touched! You really are an amazing fellow, no wonder Tamamo and Musashi chose you! You understand me! The first to understand me other than my brother...

Ushiwakamaru walks in front of Y/N and bows

Ushiwakamaru: Lord Y/N Emiya Von Einzbern, I will swear here and now upon you. As a warrior, I will protect you, wherever you go

You: And I, vow to you, Ushiwakamaru, that I will be a master fitting for you

Ushiwakamaru: Hai!

You: Hehe... ah!

Y/N holds his head as Ushiwakamaru gives him a hand to stand up.

Ushiwakamaru: What's wrong Milord?!

You: Siegfried... has been summoned.
