This feels like a rip-off of the other story here. Interesting...

shirou wank that's fun to watch

There are so much ...'s in the story it kinda makes me wonder if you don't know what commas are.

hmm, from what route again this shirou? is it altered Heavens feel?

This is just really interesting and I can't wait to see what happens next. Please continue

He could just say that many cities have been wiped out and erased from all data base entirely to keep the secret that she is seeking...

Can’t wait to see Shirou in the Grail war how will he hover come Cater, Lancer and Assassin. Can’t wait to know and will another a Master also be in the iS Academy?!

Good story and it is a fun mix of IS and Fate.

Man what's EXAMINATOR ?

Cool work! Add other servants for shirou's harem! Hope update soon! Great job!

Yep, it's Saber, Nero and Okita Souji.

Hmm. Altria, Nero and Okita Souji?

Hm, interesting. I do find it funny how he summoned three Saberfaces of the Saber class. Curious to know what will happen next.

Erm, um, I'll have to say -possibly rub it in your face- that A vaccine is used to prevent sh*t from touching you. Besides, you'll need medication to actually make sh*t go away -or go away faster-. Your pacing is not regular and thus, it's considered as terribly paced. You made the characters too OOOC -that is, Originalized from an Originalized from an Original Character-... It makes Unlimited God Slaying Works Shirou look normal compared to this. Meh, that's all. Have a nice day, and hope you look back on your mistakes. I hope ya do.

Shirou was still sore, but he found that his magecraft has further increased, he was now able to draw from Aka no Kishi's IS core, apparently IS power was a good replacement for magecraft.
Since he said she could empower a Servant for 3 years I do not see why he is surprised. If it can do that why can it only power an A rank NP once? The former takes far more power than the later, especially without the Grail.

Aka no Kishi
The name means Red Knight doesn’t it?

Does that mean they have met Caren as well? Did the pseudo war happen as well (with Ahriman pretending to be Shirou)?

That Café was the interdimensional one isn’t it?

only person to being able to use a Noble Phantasm, the Fragarach
Technically Shirou can use it as well…although it isn’t the real Fragarach; the abilities of hers is very different from the myth, although hers is created due to the blessing of a god on her family line (Sorcery Trait). The ones she uses is not the ones her ancestors used although it is the same.

well he had a conceptual weapon that could make clean up relatively easy.
Which one?
