Shirou Emiya (Prisma)

Much like his counterpart, Shirou dresses in a white and blue sleeved shirt and slim blue jeans, albeit both of which are introduced shown in ragged condition due to his imprisonment. The most notable difference lies in a small streak of white within his otherwise auburn hair as well as several tanned streaks of skin throughout his body, the changes of which most likely came about due to the extensive use of EMIYA's influence slowly growing within him in this timeline

Shirou is always taking care of Miyu be it buying her a library of books since she can't leave the house, doing her hair, or buying her stuffed animal pajamas. Shirou was very uncomfortable with Miyu's Magical Sapphire Attire feeling he needed to scold someone.

Shirou was also extremely close to Sakura. He cared deeply for her, but it was unknown if he possessed any romantic feelings for her. He is deeply hurt when he finds out she was a mage, and a competitor. When she asked him to leave with her, he felt he would be happy as long as she was by his side but felt he could not truly abandon everything the most important, Miyu. Lastly when she was killed, he felt great sadness, rage, and was horrified, but her death gave him the resolve to gain all of the class cards and save Miyu. He is deeply shocked when he discovers that Sakura has been turned into a doll. Shirou also seems to be a bit more sarcastic and laid back initially than when compared to his alternate selves, often teasing Julian when they were in high school together. However, this part of him disappeared as the war progressed, mixed with guilt, regret, desperation and biting despair at the loss of his loved ones and at that time also Miyu. Overall, his personality seems closer to EMIYA than to the other Shirou Emiya's. Yet, he incorporates EMIYA's dark and ruthless sides more than his lighter teasing sides.

His sword skills are also worth noting, as he seems to employ a fighting style similar to that of Archer's; a dual wielding style that allows him to fight against far stronger and faster opponents by usage of various tactics and exploiting every detail about his opponent's abilities. When Sakura attacks the Emiya's residence, he is seen using a long bow and using projection arrows to attack from the shed, demonstrating great archery skills.

This iteration of Shirou is also capable of evoking a variant of Unlimited Blade Works, one that is covered in snow. He keeps a tape measurer on hand that he reinforces into a makeshift sword at any time. When he tried to get into the Ainsworth residence, he purchased several Black Keys from Kotomine hoping that their affects would cut through the barrier to no affect, it is unknown if he still possesses a few in storage. 

Shirou Emiya is also proficient in using modern weaponry in this world, as he utilizes Kiritsugu's Calico M950 to fire bullets at Sakura as well as tossing grenades. He also has set land mines around his house in order to disorient Sakura as most likely she cannot utilize Knight of Honor against explosions and bullets already fired. He also appears to be in possession of Kiritsugu's Thompson Contender and Origin Bullet's and has granted one bullet to Kuro for the upcoming fight though he has not been seen utilizing them

Shirou Emiya wields unmatched swordsmanship, his abilities honed through relentless training. His keen instincts and strategic mind make him a formidable warrior. Shirou was the user of the Archer Class Card before it came into the hands of Illya, and he displays control over it to the degree of reaching a Complete Install. He is shown to have greater experience than an actual user of it, such as Kuro, as she's stated to learn how to best use the card's powers after watching Shirou fight. Just like the Heaven's Feel iteration of Shirou, this Shirou is heavily affected by the Archer Class Card. As a result, the more he uses his projection powers which "don't belong to him", the more he gets consumed by the powers, which causes physical changes as he slowly turns into a younger version of Archer. Due to having the EMIYA Heroic Spirit possess him, he shows many times he has acquired somewhat superhuman attributes such as immense strength and agility, as well as an abnormal degree of healing, though it is limited to cuts and broken limbs. Shirou uses Projection with great efficiency. He is able to run through a field of Heroic Spirits that leaves the members of Illya's group easily pushed back, attacking and defending as he moves. He is able to project a Divine Construct, Ig-Alima, for which even Gilgamesh praises him despite it being a hollow knockoff of the real weapon. It appears that this is due to Miyu's blessing fueling him with magical energy. In this world, Kiritsugu also trained him properly and he can reinforce objects perfectly. His sword skills are also worth noting, as he seems to employ a fighting style similar to that of Archer's; a dual wielding style that allows him to fight against far stronger and faster opponents by usage of various tactics and exploiting every detail about his opponent's abilities. When Sakura attacks the Emiya's residence, he is seen using a long bow and using projection arrows to attack from the shed, demonstrating great archery

Beneath his calm exterior, Shirou Emiya hides a relentless drive, forged by loss and duty. Few see the storm within.
