Let's start from Zero to a new Order! (Fate/Grand Order x male reader)

Chapter 39 Fate/Stay Night Arc 16

3rd Person Pov

Upon arriving at the church, Y/N and Rin were given treatment from Kirei. Even though Y/N didn't want that, Kirei insisted.

You: Kotomine... how is Rin?

Kirei: She was weakened pretty badly. She will regain consciousness soon

You: Good, then I'll be going to save Illya and Sakura.

Kirei: Sakura has switched sides, correct? Come with me, boy.

Kirei explains that Zouken's real objective was to get Sakura as an empty shell to gain the grail. Upon reaching a garage, Kirei agrees
to work with Y/N.

You; ... What about Medusa?

Kirei: Better not, even though she sees you as her actual master now, she plans on saving Sakura, isn't that right?

You: Fine...

Y/N looks up to see Medusa up on the roof of the church before Y/N gets into Kirei's car as they drove towards the castle of Illya

Kirei: Your father severed human emotions for the sake of his justice, correct?

You: Wrong. Even though he looked as if he was a lifeless corpse, my father had good ambitions for this world, something you can't understand.

Kirei continues to ask the boy about his father as Y/N answers them to a limited amount.

Time skip

After a while, the arrived nearby the castle as Y/N packs weapons needed. He was becoming like his father if not better than him.

The two then walked into the forest towards the castle as they stop to see it.

You: The last time I was here... Bad memories... Heracles, Artoria...

Y/N and Kirei then scan the area as Y/N uses Trace On to scan the area.

You: Third floor, left most room. 

Once done, Kirei asks if he was okay with Mountain Climbing. Of course not, so Kirei picked up Y/N, and threw him towards the window where he was from

You: That's what I get for trusting a priest!

Kirei; Good thing you were light, so using one arm was enough for us

Illya: Y/N, why did you come? Go home, there's nothing left for you, leave Sakura to me.  My duty after all is mine alone

You: What an idiot you are. I don't care about your duty! You can't fool me, I know you the best, I've stayed by your side, heck, I even went across the world just to find a way to get you back! You're just trying to act tough!

Illya: What do you mean trying to act tough?! You and I are part of the grail! If one of us is sacrificed, the other is-

You: You are still acting tough you idiot! Don't sacrifice yourself for others!!

Illya: Look who's talking... ever since we were kids, you were the one who'd go with dad to fight for me and mom... and when you returned and told me everything... I just want to give it all back to you for everything...

You: Illya, please.

Illya: ...

Kirei then picks up Illya as Y/N jumps out the building.

You: I always wanted to do that! Worth it!

Illya: Archer is drawing you over.

You: Interesting... what about those two?
