Shirou means White or Professional, and Emiya literally means Guardian. It's kinda funny on how Archer EMIYA is a Counter Guardian.

Interesting. This Shirou Emiya is 20 Years Old, base on what he stated, making him closer to the age of the OG Minato Sahashi. Yet, at the same Age, the Year is supposed to be 2020, with Shirou being 15 turning 16 at 2004, meaning that he's supposed to be 32 at the Moment, and born at 1988, unlike Minato who's turning 20, born at 2000.

I know this comment isn't truly needed, but Imagine the Dates being accurate. Making Shirou 13 Years Older than Yukari, who's 18, possibly turning 19.

While I'm looking for the Exact date on when the Sekirei Plan Starts, aka when Minato meets Musubi, I found the words "1999, 21 Years before the start of the Series" states that it started at the year 2020. which is Funny if you remember that the Corona Virus occured during December 2019, making 2020 to be the Lock Down Year, and the end of Fate/Grand Order, story wise. Making Shirou, who's born around 1988 to be 32 at 2020.

Minato Sahashi on the other hand, is stated to be 19 Years Old, turning 20 at the 15th of September, meaning he's born at the year 2000, with his sister Yukari a Year Younger than him.

Takami Sahashi is with Minaka during 1999, making her to be over 21 Years Old, with graduating College around the age of 21 to 25, and with this Information and believing that she's working at least 5 Years on her Job, she should be around 45 to 50 Years of Age.

If we go with this, the fact that Shirou should be 32 Years of Age, Takami would be around 13 to 18 Years old to have him. Between after High School to before College.

It fits when you consider her having White Hair already. Since it's around mid 20s when a person would start having gray hair and around the age of 50 when they could have their hair to go fully white.

I have a Suggestion that I'm sure nobody, but me (I hope), ever thought of, Shirou Emiya is Harry Potter!

I understand that in Most Cases Shirou's born around 1988 while Harry is born at 1980, but that can easily be ignore for I'm asking for a Fanfic.

Anyways, the idea steam from the fact that Shirou has no Canonical Birth Date. The major difference would be Kiritsugu Emiya does know both the Wizarding and Moonlit World, as well as friends with Lily Joan Evans, now Lily Potter, before her death, so after Shirou used Accidental Magic on him that Cured him from his Curse when said kid turns 9, he decided to dig deeper of who Shirou is, especially when Kiritsugu finally noticed on how similar looking Shirou is to Lily.

In short, this Shirou would be thought both Wizardcraft and Magecraft Properly, with the help of Waver, who view Shirou's inability to learn other Magecraft due to being an Incarnation, as a Challenge to become a better Professor and a Magus, even after Shirou got Blood Adopted by Kiritsugu Emiya Legally.

I also suggest Shirou finishing Hogwarts at his 4th Year, which he actually killed Voldemort in the end and the rest of his Horcruxes were destroyed early and obtaining all 3 Deathly Hallows, just in time with the 5th Holy Grail War the next Year at February, hell, you could even add Apocrypha, which was stated to have Occurred around September till November at the same Year.

For the Fun of it, since nothing Much would occur, add another Anime or 2 into the Mix that confuse the hell out of all 4 Parties, like To Love-Ru being Scientific Alien themed Anime, and High School DxD a Mythology Themed Anime, with all 4, aka the Wizarding and Moonlit World view of things. With 1 Major difference, Shirou wanted a Normal School life after the Idiocy that is the Wizarding World.

Hufflepuff Shirou who always says "I'm not Harry Potter."

This is definitely one of the best works I've read. It’s the same with a harem. You managed to make the interaction of the characters in the harem really interesting, no one faded into the background, this is a real talent! I had never watched Sekirei, and therefore immersing myself in this world together with Shiro was incredibly exciting. Thank you so much, it was incredible!

So Archer was there! Kinda. And Shirou really might have made it nearly to the root. The conscious mind can't process that though, so the experience ends up being a persistent, reoccurring dream.
I enjoyed the ten year later view of how things have changed!

Woah! What a fight! I really enjoyed Shirou attempting to scare off the other Ashikabi, getting some allies, taking out (and then Winging) Karasuba (which I totally didn't see coming!), and then storming MBI! How nice that the mere existence of the Jinki let Shirou bullshit his way into covering magecraft as simply alien manipulation lol!
Unlimited Blade Works! He got the Marble overlaid on the world! All thanks to the boost from his Sekirei and how they've helped him grow as a person. The power of love, just like Musubi said! Kuu and Akitsu were practically euphoric inside, surrounded by swords. Karasuba seemed to have fun too. She really jumped straight into the deepend and swam.
Minaka is (probably) dead and Yukari tried to stop it. I wonder how this will impact their relationship, and Shirou's relationship with Takami too.

Unwittingly agent of the Counter Force or not, Shirou is giving his all to shut down whatever Minaka's last Mystery is. Wouldn't it be funny if Archer pulled another last minute assist by popping up in the distance like he did in the Shirou v Gilgamesh match? But I know it'd detract from Shirou's first successful usage of Excalibur, so highly unlikely. Still, Archer getting spotted in the distance by Shirou might be cool to demonstrate just how close the world was to the Nuclear Option(tm).

Minaka is a magus! Damn, I should have thought of that. He's certainly over the top enough for it all to just be a public persona. And having the whole city as his workshop? *low whistle* also, lol on him being both a Kiritsugu fan boy and annoyed at Shirou claiming him as his sole father. Oh Shirou, the surprises aren't over! Leaving Minaka as simply a scientist who has uncovered aliens and magic would have been just as compelling but I'm eager to see how this goes!
Tomorrow huh? Can't wait to see who shows up outside MBI and how that might help and hinder Shirou's plans to keep Minaka from doing anything dangerous enough for Counter Guardians to show up. Shirou is really jumping to the worst case scenarios, but he certainly has reason to! Archer's memories in his head don't help with that.

I wasn't expecting the fight between Shirou, Rin, and Saber to take that turn, but I loved it anyway! And poor Shirou, feeling Emotions about it and recognizing that they are Emotions. Rin was right that the Sekirei are helping him.
I've greatly enjoyed the meeting of old and new loves and can't wait to see what (if anything) Karasuba does with her new knowledge.
Lmao, that moment when you run off with a broom instead of an arm because it'll annoy 01!

DAMN, What an amazing story I'd give it a 9.5 out of ten it would've been a straight ten if miya was winged by shirou! I mean it's completely possible by your fic's logic, shiro was a helluva lot strong than takehito canon minato and he sure as hell connected more with her than even karasuba!
Also what happened to everyone else like seo and the twins, uzume and chiho, and all the deactivated sekirei?!
Still a solid 9.5

HOLY FUCKIN SHIIIIIIIIT! EPIC, LEGENDARY, EXTRAORDINARY!

Daaaaaaaaaaayyyyyyyaaaaammmm! DraMAAAAAAAAAAAAAAAAAAaaaaaaaaaaaaaaaaaaaa!

Bummer man, I was hopeful the the two could've somehow joined!

OHHHHHHHH FUUUUUUUUUUUUCK! WELP So much for being a hero, he's about to die horribly! In the famous words of shorty from scary movies"RUN BITCH RUUUUJUUUN!"

WOOOOOOOOOOOHHHHHHHHHOOOOOOOOOOOOOOO! Though I would've liked the bastards sliced up and bloody! I wonder if shirou will EVER tell takami and yukari the full story!
