3rd Person Pov

Astolfo: So, what should we do with that fat bum there?

You: I will take care of him. Jeanne?

Jeanne: Go ahead

You: The flame is the soul's breath, The black smoke is the soul's release, ashes thou wert and art l, may thy soul... return to the great flame Látom

Y/N stabs the man with his spear before he disappeared. Jeanne does a check on Y/N and the boy as they were both okay. However, just as the coast was clear, the entire black faction arrived

You: Shit...

Astolfo: Oh boy... jeez. So they are here

Darnic: Rider, what happened here and who is that servant?

Astolfo: Uh...

Jeanne: I am the adjudicator of this Great Holy War, Jeanne D'Arc, Ruler Class

Vlad: What happened to Saber?

Astolfo; He chose to die by his own hands, I guess?

Caster: Then what exactly is that homunculus, the older one, who holds Saber's heart?

You: (They are on to me!) Alright, alright, I give up. I am Y/N Emiya Von Einzbern, son of Kiritsugu Emiya and Irisviel Von Einzbern. Me and Siegfried are one, heart and soul! As for your pathetic master here, he's dead, by me.

Astolfo: Do you have a death wish?!?!

Jeanne: If Y/N talks like that, then that means he has a plan involved here. (To black faction) I will not have this man become your puppet. He is no servant and he is your enemy, but there are still rules here. The boy here also isn't part of this either.

Caster: But still, I still want that boy back. He has no persona, he was built to fight and was counted as death fodder.

You: Even so, he isn't part of this war. As if he had a choice to begin with. Besides, if Siegfried unleashed his noble phantasm, Frankenstein would have been dead a long time ago

Vlad: Still, you tried to save this Homunculus along with the fact that you keep Saber's heart and killed his master

You: Hmph. You better watch your step. Because multiple servants are above you (Thank you, Skadi)

Frankenstein growls again as she senses more than one enemy servant in the area. With that bring said, Astolfo was brought back as Sieg, Y/N, and Jeanne to a place where Sieg could live his life to the fullest. Sieg takes the sword given to him as they leave.

Sieg; Breathing became easier

You: Good for you. As a homunculus myself, I commend you for denying death

Sieg: You're one too?

You: Yup, we're the same after all. Except that I was born by a family. Now, I will give you what you want as well

Sieg; I see. Your name was Y/N... Emiya Von something right?

You: Just call me Y/N

Sieg: I see. Then I'll call you, Ruler, is that alright with you?

Jeanne: That is fine with me.

Sieg's stomach rumbled a bit as Y/N laughs before he gives him a small biscuit

You: An Army runs on their stomachs, they say. Just like normal humans, we homunculus need to eat

Sieg: I see... nom... Delicious

You: I'm glad you like it. Most servants don't need food, they eat if they want, but Jeanne and her sister, Jalter, wasn't summoned for the war, they were summoned to watch over the war and how it'll play out.

Sieg: That answers my question on why she needed to eat

You: Yeah, her body belongs to someone else. However, after the Grail War in Fuyuki, she and the person inside became one.

Sieg: This war feels different. Siegfried mentioned how he was missing something, I am too, but I don't know what it is

You: Right now, you have freedom and do, you can do whatever you want.

Sieg: I know... but about the master you killed, he was just fatally injured, he's still alive

You: To think that little prick would live Diarmuid's spear. We'll worry about him later, come on. Right now, we need to rest up and head to Sighisora

Jeanne: What for?

You: Jack the Ripper, famous killer of Great Britain has awoken. News has spread that his previous master was killed and is now taken in by an outsider.

Jeanne: Then we must go. Huh? Where's Skadi?

You: She went home to rest, but she and the others will be here shortly. For now, let's rest up

Sieg/Jeanne: Hai.

Y/N brought Jeanne and Sieg to a cottage nearby as they ask for Sieg to stay nearby.

Sieg: Will I ever see you both again?

You: Time will tell, Sieg. Right now, it may not look like it but... we'll see

Jeanne: Goodbye, Sieg

Sieg walks away as Jeanne looks down. Y/N holds her hand as she was taken a back.

You: You didn't want him to fight, right?

Jeanne: Yes, but it also felt I said goodbye to you. You both looked the same so I expected it to be you

You: I see... well. I got message from Waver Velvet, he says that all the victims of Jack were all spies and his own master, were all killed too.

Jeanne: If it's Jack the Ripper, he's most likely an Assassin.

You; Yeah, I'll call in Serenity. If anyone can match an assassin's speed, its Serenity. If not, Scathach. Usually, an assassin's speed is higher than most servants but with their own class and Lancers, they are equal if not higher in speed

Time skip

When Y/N and Jeanne arrived, Jack had already left as Y/N sees a Noble Phantasm in the sky.

You: Follow it!

Jeanne: On it!

Y/N and Jeanne follows the flying ship until night fall where they were ambushed by golems and skeleton warriors

Jeanne: Y/N, I need to meet with him, Shirou Kotomine!

You: Alright! I'll distract them! Ushiwakamaru, Musashi, Ishtar, and Tamamo, come to me!

Ishtar: What do you need of us, Master?

You: Ishtar, protect Jeanne and go with her inside the castle Garden of Babylon. Musashi, Tamamo, Ushiwakamaru, you three will help me distract the undead and golems while Jeanne and Ishtar make a run for it.

Musashi/Tamamo/Ushiwakamaru: Understood, Lord Y/N

You: Now! Run for it, Jeanne, Ishtar! Gae Bolg Alternative!

Y/N kicks Diarmuid's spear as it turns into multiple spears, clearing a path for

Tamamo: Scatter and perish before the Higanbana Sesshouseki! Yin Concentrated shot!

Musashi: O gods of Izumo! Let this be the proof of your purity, as this mirror becomes your sacred treasure- Eightfold Blessing of Amaterasu!

A spirit of a samurai appears before Musashi as she slashed downwards and so did the samurai spirit.

You: Is this an Anti-Fortress Noble Phantasm?

Musashi: You can say that!

Ushiwakamaru: My lord, don't get too cocky, behind you!

Ushiwakamaru blocks a nearby golem's attack as it shattered into pieces

You: Thank you, Ushiwakamaru! Those rocks... huh?!?!

Y/N looks up as he sees a rain of arrows coming towards them, a Anti-Army type of noble phantasm

You: Brace yourselves!

???: Wall of Camelot!

Someone came in between the noble phantasm as Y/N saw a shield, one that represented the hopes of everyone as it manifested into a wall until the Noble Phantasm died down

???: Are you alright, Senpai?!

You: Y-Yeah. Who are you?

Mashu: I am Mashu Kyrielight, the first Shield Class Servant. Senpai- No, master, what are your orders?

You: A shield? That's new. Wait, that shield, then that means you're Galahad's Reincarnation?

Mashu: No, I only do what Galahad does, but to put it simply, yes, I am somewhat like Galahad.

You: I see. Then for now, we must distract these monsters from getting to Jeanne D'Arc and Ishtar

Mashu: Understood, Sen- Master!

You: (She really sees me as a senior.)

Y/N then sees a vision of where Frankenstein was battling someone familiar

You: Shakes Spear? He's a hero?! Musashi, I need to be somewhere else.

Musashi: Got it, just don't run from a battle

You: I'm running away from one already!!

Caren: (Y/N)

You: Caren?

Caren: I've joined this battle too. Right now, I am following Shriou, you take care of his servant

You: Got it.

As Y/N arrived, he saw Shakes Spear walk away while he saw everything that Frankenstein had went through, how she was neglected by everyone, even her own master

You: Caules Forvedge Yggdmillennia, you can hear me, right?

Caules: That voice, the Homunculus with Saber's heart??

You: Yes. Don't use a command spell, let me handle your servant. No worries, I won't kill her

Caules: ... Fine!

Y/N watched as Frankenstein destroy a doll which looked exactly like her master

You: Based upon the artificial life created by Victor Frankenstein in Mary Shelley's novel "Frankenstein: or the Modern Prometheus". Victor sought to recreate the original couple described in the bible -- Adam and Eve. Due to the limitations of man, he first built Eve, intending for her to give birth to the counterpart.What started as a patchwork of lifeless flesh was given life by the energy harnessed from lightning.Unfortunately, what awoke was not the ideal woman that Victor envisioned, but an abomination with the mind of an infant. Having no developed capacity for expression, her sense of morality was completely absent. After presenting the entrails of a slain dog as a gift for the master, she was branded a failure and disassembled, before being abandoned completely.

Frankenstein looks towards Y/N but didn't do anything as the boy hugs the monster

You: Calm down, you just wanted to be noticed, to be loved by someone.

Frankenstein: Hm... hm...

You: You wanted to be treated normally. Here.

Y/N picks up a flower and gives it to Frankenstein

You: You feeling better now?

Frankenstein nods

You: Good, now go back to your master

As Y/N was about to leave, Frankenstein stops him

Frankenstein: Th...ank... you...
