The Holy Grail War is Over, But Is It Really the Dragon Clan?

[On the first day of my journey, wearing an Adidas battle suit and sporting dark red hair, I am actually Shirou Emiya?]

[By the third day, I confirmed it: this is not the UBW route, and without the Red Archer experience pack, I have to rely on myself to master Unlimited Blade Works.]

[By the twentieth day, I have mastered reinforcement magic and started practicing projection. During this time, I encountered an alchemist who asked me where I got so much regenerated metal to make alchemical weapons.]

Regenerated metal? What the heck?

[By the ninetieth day, I finally succeeded in projecting my first Noble Phantasm. They exclaimed that this is an outstanding achievement of alchemy, the 'Seven Great Kingdoms.']

Huh? I don’t really understand you alchemists.

......

[By the xxxth day, yay, I finally mastered Unlimited Blade Works! Their expressions were priceless as they asked where this Nibelungen came from.]

How do they not even know about the Reality Marble? Isn’t this... the Type-Moon universe!?
