Tips for reading the article: the main perspective will be [Captain] + [Kiana] + [Civilization in the first half] + [Daily life after the collapse in the second half]

Not a title scam!!

The pace was very fast, and it collapsed after about 80 chapters!!!

In the previous era, he was the [Night Watchman] of the beginning, and in the present era, he is the [Lamp Bearer] of the end. The boy who was born because of the concept of [Captain] once cut off his [past], [present], and [future].

If the life of K423 was a stage set by Otto, then the existence of the boy seemed to have been arranged by fate.

Finally, please allow me to once again state the significance of my appearance in this world...

[Day 1 of the time travel: Wearing Adi King's battle suit and dark red hair, is Emiya Shirou actually me?]

[Day 3: Confirmed, this isn't the UBW questline, no Red A experience packs, so I'll have to rely on myself to master Unlimited Bladework.]

What the hell is recycled metal?

[Day 90: Finally mastered my first Noble Phantasm, Projection. They exclaimed, "This is the Seven Kingdoms," an outstanding achievement in alchemy."]

Huh? I don't really understand you alchemists.

...

[Day xxx: Huh, I finally mastered Unlimited Bladework! Their expressions were fascinating, and they asked where the Nibelungen was.]

How come you don't even know about the inherent barrier? Isn't this... Type-Moon!?
