(As the group proceeds further into the cave, Morgan feels a faint energy.)

Morgan: The Greater Grail is back here. It's a little far back, so don't get lost.

Mash: This place looks like a natural cave... did this actually exist in Fuyuki City?

Y/N: Fuyuki City? That's how this place is named?

(Gudako and her servants nod in agreement.)

Francis: This cave is half-natural, half-man mande. It's the underground workshop expanded by mages over a number of years.

(Y/N then turns to Morgan.)

Y/N: Uh... Morgan... what is this Saber's true name? It looks like you fought for years.

Morgan: Well, anyone who gets hit by her Noble Phantasm will find out that bastard's true name. The other servants were all defeated because Saber's Noble Phantasm was extremely powerful.

Y/N: A powerful Noble Phantasm? What is it like?

Morgan: The sister sword of the sword in the stone. It's the most famous sacred sword in this time period. It's name is...

????: The Sword of Promised Victory, Excalibur. Wielded by King Arthur, the noble King of Knights.

(Everyone turns to see a Shadow Servant.)

Gudako: Is that... Archer?

Morgan: Ah, speask of the devil. Or should I say, the faithful follower. As always, I see that you're still the loyal knight.

????: Hmph, I don't remember becoming the servant of anybody. I'm here to chase away unwanted visitors.

Morgan: (stern) In other words, you're the gatekeeper. I don't know why you're protecting Saber, but let's end this here. Isn't a game that never ends boring? For better or worse, we need to move the pieces forward.

????: From the way you talk, I think you understand the circumstances. Yet you are still absorbed by your own desires... You still haven't changed. In that case, I will knock some senses into you.

Morgan: Ha! Big talk for a mere Archer. Let's go!

(The Shadow Archer summons three Dragon Tooth Warriors, and Y/N fights one of them, easily overpowering him as Salter and Jalter fight the second Dragon Tooth Warrior. As Y/N defeats the first Dragon Tooth Warrior, the second one is holding his own against Salter and Jalter but Y/N slashes it, defeating it.)

Salter: Come on, we had him.

(Gilgamesh is seen easily defeating the third Dragon Tooth Warrior.)

Gilgamesh: Stop whining, mongrel, and let's deal with this Fake Archer.

????: HOW DARE YOU?

(Two more Dragon Tooth Warriors are summoned as they try to slash Y/N, who blocks their attacks while Shadow Archer shoots an arrow which almost blasts Y/N away, but he quickly dodges the attack with his empowered Petal Burst. Salter easily destroys one of the Dragon Tooth Warriors with several slashes. Shadow Archer charges at Y/N and their weapons clash as Baobhan and Barghest slash and easily destroy the second Dragon Tooth Warrior.)

Y/N: Just you and me, Archer!

????: ONORE...

(Y/N blocks and dodges the Shadow Archer's attacks before trying to slash him, but Shadow Archer evades as well and throws his two swords at Y/N, who blocks the weapons as he manages to block his other attacks.)

Y/N: THIS ENDS HERE!

(Y/N then slashes the Shadow Archer continuously before shooting him, and then he performs his final slash as the symbol of a shattered moon appears. The Shadow Archer is brought down as he coughs blood.)

????: Well done, Rose Huntsman! Who knew you could defeat me without needing to use the Crimson Dragon Emperor Sacred Gear.

(Then the Shadow Archer dissipates.)

Morgan: It's past time he took a hike. We shall take down that sacred sword.

Y/N: (to Morgan) I'm glad you trust us, but do you think there is a way to guard against that sword?

Mash: Hmm... I've heard about the Sword of King Arthur. My fingers are trembling, it seems too much for me...

Morgan: You just need to overcome it with your courage. Look at that cutie pie. He seems to be perfect for the job as his spirit never shatters. Your spirit will only shatter if you lose it. Don't think about the sword itself. Your focus is to protect your master. That's right up your alley, no? Anyway, leave it to me to finish off Saber, and just do what you need to do.

Mash: ...Right.

Y/N: That advice will be of great help.

(They proceed for the Greater Grail as the screen fades out.)
