This Shirou is my own creation.
This Emiya shirou is based on the assumption that the archer card is similar to archers arm from the heavens feel route. Meaning without the card Shirou lacks the connection to EMIYA and so does not have access to EMIYA experiences, arsenal and his reality marble.
Where it differs from the manga and anime is that this shirou is half invaded but since he had finally became real, he became fundamentally different from EMIYA, which stopped the invasion and in turned purged EMIYA from himself, becoming Shirou but at the cost of EMIYA's abilities and experiences only leaving behind his origin, element, and some blueprints. Since this takes place on more of a soul level, Shirou's body still retains parts of a servants power.
This shirou looks like normal shirou except with black hair instead of red, due to his origin and reality marble.
This Shirou has two types of mentalities, his normal self and his villainous self. In terms of his mentality he is still distorted but in a different manner to the fate Shirou. He has no qualms about dooming a world for his sister Miyu and there lies his distortion. He will eliminate anything for her and he doesn't care about the methods, after all he was raised as Kiritsugu assistant. He has killed before personally and a lot more indirectly when he was a child.
Normal Shirou is just like a normal person, he will be selfish, he has his own goals that he truly believes in. He does not believe he is a sword so this would cause issues when he tries to perfectly emulate EMIYA's abilities at projection magic. He has his own path to walk and so he is not a faker who copies other's.
His background story would be tweaked a bit to fit my needs. Think of him as a proper magus version of Shirou, he doesn't mind being nice and helping others if it's small favours, eg buying a train/bus ticket for someone who forget his wallet. But he wouldn't go the extra mile anymore.
Both are Shirou but if one was to say which is the one that is real it would be the villain as it reflects his reality marble
In terms of Origin I'm aware that you can't have 2 origins (never stated but implied.) But this is fanfiction which allows me some leeway. So basically im combining the two into one to make darkness and sword.
Shirou Emiya – Human/master (nasuverse servants stats.)

Personal skills
Eye of the mind (true) D-
An insight attained by years of training, discipline and experience.
If you encounter this story on Amazon, note that it's taken without permission from the author. Report it.
A combat logic that allows for calm analysis of the situation and the enemy's ability in spite of danger, and consideration of all possible actions in a particular situation.
Since Shirou lacks the necessary combat experience this skill is weakened.
Magecraft B
Having being properly trained by Kiritsugu he is well versed in being a magus, however due to him inheriting EMIYA origin and element, his skills aside from his specialities (reinforcement, projection etc.) has weakened massively however in exchange the former is strengthened.
Projection magic D (A+)
Inheriting EMIYA's core abilities has allowed Shirou to use Tracing a unique variation of gradation air. However due to the lack of training, the projections take far longer to create effectively making it worthless in close combat.
Knowledge of the occult B
When Shirou was raised by Kiritsugu, he assisted his foster father with his journey of being a hero of justice. Sifting through various different fields they searched tirelessly to find a method to save humanity, eventually their search led to Miyu.
Knowledge of modern technology and weaponry D- ©
Raised as Kiritsugu assistant Shirou knows how to use modern technology and weaponry, including the construction of explosives and the strategies employed by Kiritsugu against magi. However his knowledge has dulled over the years of inactivity.
Hawkeye B+
By reinforcing his eyes to the limit it allows for him to see much further than humanly possible.
Cooking C+
From a young age Shirou was forced to learn how to cook for himself, since his foster father Kiritsugu had no talent in household work. At first it was a chore but eventually he started to love cooking, especially since it helped him empty his mind from disturbing thoughts as well as bonding with his little sister.
Affections of the true holy grail – EX (Unlike Illya and Sakura whom are lesser grails, Miyu is a true holy grail as she is considered to be a child of god. Rather then being created for the holy grail war like the former, the holy grail war was created for Miyu.)
This is a skill for one who is deeply loved by a Holy grail, in some time and place. One could call it the greatest curse in the world.
This skill boosts the rank of the recipient luck to exceptional heights, even to the point it allows the recipient to break out of abilities that would normally be impossible to escape from. However this good fortune comes at the expense of other's happiness. Once the recipient is aware of the skill, it allows him to sense the location of the holy grail by following the connection as well as hearing whispers from the holy grail.
If Miyu/holy grail exists in the same world as the recipient, a magical connection is created between Miyu/holy grail and the recipient. (when the holy grail is Miyu gives EX mana, otherwise gives A+.)
Archery C
Shirou could be said to be an absolute genius in archery, having never missing a shot at a target with the only one missing being intentional. However since he lacks practical experience of shooting a moving target this skill is weakened.
Older brother's will EX
This skill symbolises Shirous determination to save his sister Miyu at all costs, he is willing to choose her over the world and would annihilate anything standing in his path.
The effects of this skill negates any form of mental interference when Shirou is in this mindset, over wise it gives a buff to his mental fortitude.
Noble phantasms
Known blueprints inherited by the archer card. Rho Aias, Kanshou and Bakuya, Caladbolg II, Gae bolg , Excalibur , Hrunting , Archer's bow.
Known blueprints he discovered, some of Gilgamesh's arsenal, Sul-Sagana, Ig- Alima.
Hidden weapon Erebus (this would be locked for a long time since he came from another miracle. If you want more details about it check out a warm share of happiness.)
(tentative name haven't thought of it yet.) Reality marble - left blank on purpose, until I reveal the abilities in the story.
I am the darkness that shrouds all
Steel is my body and darkness my heart
I have made many mistakes
Always searching for the ever distant stars
Not realising the stars beside me
Yet not all is lost
So I will be the dark night separating the stars
Granting despair to all that seeks the hidden stars.
