Special thanks to /u/kannazuki for reminding me of Arthuria's lines and /u/taiboo for correcting me!!

Upon summoning: I am Saber. A servant that will protect you and the world.

General 1: A mission? Then, I will accompany you.

General 2: Master, your growth is impressive.

General 3: Although Servants are beings that obey their Masters, it is also good to have trust between each other.

If you have Merlin: Is Merlin here? Oh my, this universe’s Merlin is a guy, huh. So things like that exist too.

If you have Arthuria: I heard a voice just now. Is Merlin here? …eh, Arthuria? So, it wasn’t Merlin. It was a very similar voice, hence…

If you have Mordred: This universe’s Mordred is cute. Besides… No, it’s okay. I just remembered something from a long time ago.

If you have KotR members: The Knights of the Round Table exists in this universe too. Then surely, the ‘me’ of this universe does as well. I’d like to meet (them) someday.

If you have other Prototype servants: I see. Those guys are here too.

If you have (Arash?): Archer… you have not changed.

If you have Henry Jekyll & Hyde: That guy, is he Berserker? …I see.

Likes: The things I like? I’m sorry, I don’t think about that much.

Dislikes: The things I dislike too, I wonder if it’ll come up eventually… I’m sorry.

(basically he’s apologizing for not being able to tell you his dislikes because he doesn’t think about it either)

Holy Grail: The search of the Holy Grail? How nostalgic. It is not something the current me needs. If it is something evil, until it is made just…

(thank you /u/taiboo!!)

Event: There is a festive gathering of some sort. What to do, Master?

Level up: Once more, I became stronger.

Ascension 1: You ascended me, huh! This is nice.

Ascension 2: Amazing! Is this your power?!

Ascension 3: I wonder if I can answer to your expectations. This figure, with this power, I will fight from now on.

Ascension 4: Well then, let’s go, Master! The world is waiting for you!

Bond 1: Have you ever met a Saber other than me? That’s uncommon… yes, a Holy Sword-wielding Pendragon that’s not me, right?

Bond 2: I took on my mission and came to this world. Of course, I will also lend my powers to help you and your battle of saving the world.

Bond 3: I am pursuing an evil being. That is, Beast. Coming from the other side – a being which devours everything.

Bond 4: Once when I participated in the Holy Grail War, I was lost. I wondered what I should do… But my current self is no longer lost.

Bond 5: You are warm, just like a certain woman who saved me. If this sword could become some small amount of strength... then that strength is unreservedly yours, Master.

(thank you again /u/taiboo!)

Birthday: Happy birthday, Master! I wish you a wonderful day.
