Shirou Emiya (衛宮 士郎, Emiya Shirō?) is the main protagonist of Fate/stay night who acts as the Master of Saber during the Fifth Holy Grail War. He is the adopted son of Kiritsugu Emiya, the adopted brother of Illyasviel Von Einzbern and the younger self of EMIYA.



  • Shirou wounded after the fire
  • Shirou being rescued by Kiritsugu
  • Shirou hugged by Kiritsugu
  • Kiritsugu's last moments with Shirou

Ten years before the start of Fate/stay night, Shirou was an ordinary boy living with his parents in Shinto. The great fire caused by the contents of the Holy Grail spilling out at the end of the Fourth Holy Grail War killed both his parents and left him mortally wounded within the blaze. He was rescued by Kiritsugu Emiya, who was dejected after indirectly causing the fire and, wishing to actually "save" someone for the first time in his life, rescued Shirou by embedding Avalon in his body. He then later asked the recovering Shirou if he would like to become his adopted son, fully disclosing his identity as a magus. Shirou agreed and spent the next two years persistently asking Kiritsugu to teach him Magecraft. Kiritsugu eventually complied, and though he disapproved of Shirou's desire to learn his craft, he advised applying it in secret, where it could only benefit people and not attract confusion or suspicion. The knowledge he imparted to Shirou was very basic and incomplete, leading him down a dangerous path with little results. Furthermore, and perhaps inadvertently, Kiritsugu passed on his philosophy of wishing to be a Hero of Justice capable of saving anyone to Shirou.

Five years prior to the fifth Holy Grail War, weakening every day due the effect of black mud from the Holy Grail, Kiritsugu dies, leaving Shirou frustrated, depressed, and alone. He was subsequently watched over by Taiga Fujimura, Shirou's longtime neighbor and his English teacher, and his living expenses were managed by her grandfather, Raiga Fujimura. He later went to a middle school where he encountered Matou Shinji around October of his second year when he had to remake the signboard of the culture festival according to the design of third year students in a single evening. Shinji, who oversaw that throughout the evening, said “Hmm… you’re an idiot but you actually do a pretty good job.” and started to laugh.

After starting in Homurahara High School, he met Issei Ryuudou and became known as someone who would readily do anything to help others, such as fixing the school equipment. He later joined the Archery Club, which led to an estranged relationship with Shinji. He missed the target only once during the period that he was enrolled, but even then he said that he saw that “it will miss” before even shooting it. He withdrew during the summer of his first year due to a bone fracture in his right shoulder he received during his part-time job, which left a burn mark over the skin. The wound itself was nothing major, but Shinji pointed out that it was unsightly for someone with a burn mark to do a formal shooting, so he left the club as it was also a period when he was busy with his part-time job. Their relationship eventually stabilized, but some tension still remained, especially in regard to Shinji's abuse of Sakura Matou. Shirou also got closer to Sakura as she started to visit his household frequently during the period while he was injured in order to help him cook and clean up the house. Even after he was healed, she continued to come as a member of his surrogate family.

In the events of Fifth Holy Grail War, Shirou is a teenager with auburn hair and golden-brown coloured eyes. He is often seen wearing his casual clothing, consisting of a blue and white long sleeve baseball jersey T-shirt and a blue slim straight jeans. During school, he wears his Homurahara Academy uniform but underneath his jacket uniform, he wears the same long sleeve baseball jersey T-shirt.

In Heaven's Feel scenario, Shirou gains a new body designed by Touko Aozaki. His puppet body is noted to match his original body closely. He wears a long sleeve shirt with black trousers.

In Ufotable adaptation of Fate/stay night [Unlimited Blade Works], Shirou has a lot more variety of clothing. For instance, Shirou wears a black and white jersey zip jacket along with his casual clothing. He wears a charcoal coloured thomson tartan lambswool scarf along with his school uniform. Other than his casual clothing, he is seen wearing a long sleeve white shirt and a black hooded coat. He also wears a black long sleeve shirt.


Due to the trauma he suffered during the great fire, Shirou has a constant emptiness in his personality and suffers from tremendous survivor's guilt. He feels that, as the only survivor, it is unfair to the deceased to prioritize his own needs before those of others. He has a distorted sense of values where he only finds self-worth from helping people without any compensation, feeling that the very act “helping people” is its own reward. He believes it is highly unfair that some people survive and others do not. When it comes down to receiving an injury or even giving up his life to help someone, he will do it without a second thought. The people who see this side of him are often very worried and attempt to correct his behavior, though they are unable to change his opinions. Kiritsugu often talked about how he used strive to protect the innocent from the world's many perils, even at the cost of his own humanity, and how he was saddened by the reality that whenever he was able to spare one life, another person was fated to die. Although Kiritsugu was tormented by his inability to save everyone, Shirou always admired his efforts. Right before Kiritsugu's death, Shirou pledged to be a Hero of Justice in Kiritsugu's place and strive to protect everyone at the cost of his own life. Everything that he is thus far is the result of that very pledge. He has made it his dream to become a "Hero of justice" who will save everyone regardless of what happens to his own life.

Shirou pushes his ideals to their limit during the Fate scenario, where he constantly attempts to protect Saber from harm and keep her from fighting other Servants, despite the fact that she is many times more powerful than he and that even his odds of mere survival, not winning, are hopelessly low against those he personally fights. This is because he cannot stand the idea of someone else being harmed for his sake. He never gives up his ideals during the route and injures himself numerous times to uphold it. During the Unlimited Blade Works route, Shirou, through constant arguing with Archer, begins to see the hypocrisy in his ideals. Though he refuses to give them up entirely, he works his way towards a middle ground where he will strive towards fulfilling ideals, despite knowing they are impossible to achieve. He faces his largest dilemma during Heaven's Feel, where he is forced to choose between maintaining his ideals and protecting the life of Sakura. He eventually forsakes them, with the exception of the "Superhero" ending, where he becomes as resolute as Kiritsugu in his prime, allowing Sakura to be executed for the greater good. He strives only to protect Sakura, though he is presented with conflict a number of times.

Shirou is extremely stubborn once he sets out to accomplish something, such as spending hours attempting to perform a high jump that is nearly impossible for him. This action, as watched by Rin and Sakura, is one of the initial factors that causes them both to develop feelings for Shirou. He will stubbornly defend his own viewpoints, no matter how wrong they may seem to others, even to the point of causing them great mental anguish. Though he does his best to help others, if he feels that a person brought about their own ruin, he will simply watch instead of helping. He can range from being sarcastic to blunt very easily and his poor convey of body language can make it difficult for others to recognize when he is which, even leading some to think he is being dense or ignorant. Nasu has stated that Shirou and Shiki Tohno would not get along.


Shirou's love interests varies from Saber, Rin and Sakura depending on the routes. However, he has shown to be initially attracted to Saber, having a crush on her, from the moment he saw her after she's summoned, regardless of the route. In Fate, Shirou eventually fully accepts his feelings for Saber, and even desires to be with her, despite her being unable to exist in the mortal world, but they eventually reunite in Avalon. In Unlimited Blade Works, Shirou develops feelings towards Rin during their alliance and eventually becomes her boyfriend in True End, sometime teasing her in retaliation to her own. However if he also keeps pursuing his crush on Saber, then all three eventually have a mutual relationship and continue living together in Good End. In Heaven's Feel, his feelings for Sakura become major plot point, when he realizes her growing beauty and develops feelings for her even before the beginning of the Grail Wars, which drastically alters all of the following events and eventually leads him to forsake his long held ideals of becoming a Hero of Justice in order to save her.

Shirou quickly develops a rivalry with Archer after their first meeting, and is shown to be jealous of Archer's relationship with Rin in the Unlimited Blade Works route. Shirou also grudgingly believes Archer is cooler than him. Shirou can be critical of Taiga Fujimura, often berating and teasing her over her antics, although she seems to be aware its mostly playful and will try to get under his skin. In truth, Shirou greatly loves and values her for being there after the death of his father. Shirou is initially fearful of Illya but can become fiercely protective of her when they're not acting as enemies. This is even before he discovers they are step-siblings. In addition to Saber, Rin and Sakura, Shirou is also attracted to Rider.


Shirou possesses an extraordinary talent for housework. Despite having Taiga as his caretaker, he generally cooks all of her meals and does almost all of the housework while she generally does nothing. Home cooking is his forte, and he especially prides himself in Japanese cuisine. He is not a cheapskate when it comes to ingredients to make a delicious meal, and he will spend a great deal of time in order to make something extravagant. He teaches Sakura how to cook and as she improves, they eventually start to compete over the quality of their meals. Shirou equally enjoys Japanese tea, black tea, and coffee, but he prefers Japanese tea and dislikes plum kelp tea. There are times when he receives liquor from Copenhagen, but he merely tastes it as he is not good with alcohol. Among the characters of Fate, he is one of the heaviest eaters, losing only to Saber, Berserker, and Lancer. According to him: “one who does not have the stomach to digest breakfast is a failure as a martial artist.” Despite having his household finances taken care of by Taiga, Shirou does not wish to feel like a freeloader, so he has been taking up part-time jobs since middle school in order to pay for his own expenses. He earns 950 yen per hour at Copenhagen, and he receives spending money from accompanying Raiga Fujimura when he participates in his hobbies, which include sumo wrestling and hunting.[4][5]

Shirou does not feel comfortable in the atmosphere of a Game Center. He is weak against blind dates, even though he likes them. He has never gone to the dentist. His English language skills are poor and his intended major is initially in the field of law and politics. He likes repairing electronics to help practice his Magecraft, and he can become immersed for hours at a time while fixing appliances. Due to the fact that he almost never denies requests to repair appliances or work, such as cleaning the school's swimming pool before its opening, he has many nicknames such as “fake school janitor”, “in charge of mending”, “vacuum cleaner of the Archery Club” and “Homurahara’s brownie”. He likes to meditate within the dojo in his household, often to relax before or after practicing Magecraft.

While at school, he aims to be the greatest at the “who will give up first” type of contest. He once participated in sepak takraw along with Ryuudou Issei and Matou Shinji during a school festival. They advanced to the finals, but when they competed with the team formed by Kane Himuro, Ayaka Sajyou and Ayako Mitsuzuri, Issei caused a quarrel after being harassed with concentrated attacks and caused both teams to be disqualified.



  • Shirou moving into the Emiya residence.
  • Kiritsugu final moments with Shirou

Shirou appears near the end of the story. He lost his family to the great fire caused by the Grail, as he laid on the floor trying to reach out to someone. Kiritsugu found him and thanked him. Shirou was envious of Kiritsugu when he saw him happily cried in tears as if he was saved.

After being rescued by Kiritsugu from the inferno, he is adopted as Kiritsugu's son. Shirou felt more comfortable calling Kiritsugu "old-man" (爺さん, jii-san?) than "father" or "dad". In the anime adaptation, he is seen settling into the Emiya residence.

In the Drama CD, Shirou kept experiencing nightmares. Shirou would take the medicine that Kiritsugu made with magecraft. Shirou asks Kiritsugu about teaching him magecraft but Kiritsugu was completely against it.

Five years later, while gazing at the stars in the Emiya estate, Kiritsugu tells Shirou of his dream to be a Hero of Justice and how he failed. Shirou, in admiration, states that he will achieve Kiritsugu's ideal and this allows Kiritsugu to die peacefully.

Fate/stay nightEdit

See Main Route Articles for Shirou's role during the scenarios: Fate, Unlimited Blade Works and Heaven's Feel

Shirou is a student of Year 2 Class C of Homurahara School during Fate/stay night. He has no interest in the Holy Grail and instead despises its use. However, he is determined to win the Holy Grail War with Saber for he hopes his efforts will ensure that another disaster like the Fuyuki conflagration will never occur again.

At the End of the Fate scenario, he continues to pursue his dreams of being a "Hero of Justice" and hope to unite with Saber all while leading a regular life. After the True End of Unlimited Blade Works route, he is working part-time at the mansion of Rin's rival Luviagelita Edelfelt.[6]

Shirou does not end up as his alternative future self at the end of the three scenarios.[7]


The manga adaptation of the visual novel follows the Fate route with a mixture of events from Unlimited Blade Works. It follows the events of Fate normally until the defeat of Rider. Instead of Shirou being immediately kidnapped by Illya while Saber is weakened, Saber manages to recover somewhat from her use of Excalibur before the Emiya household is assaulted by Caster. Using Taiga as a hostage, Caster successfully uses Rule Breaker on Saber and takes her as her Servant after Shirou was unable to make a quick decision. When Rin tells Shirou that he is no longer a master and should not be involved any further, Shirou becomes depressed and becomes confused with what to do (noted: Shirou's feelings for Saber continue to develop).

Feeling depressed over his loss and worried over Saber, Shirou goes to the Church for shelter. At the Church, Kotomine tells Shirou that his decision to sacrifice Saber was the right choice. Enraged, hearing such a thing Shirou counters Kotomine, saying that that (sacrifice Saber) was wrong and that he never truly gave her up. Kotomine then counters Shirou saying that not accepting what he did was the real betrayal. Kotomine then reveals to Shirou that his father Emiya Kiritsugu was also a Master in the Holy Grail Wars and that he was the victor. Shirou was both shocked and horrified even further after being told the truth. Kotomine tells Shirou that Kiritsugu was the man who kill all the other masters and caused Kotomine's first death in order to attain the Grail, and making Shirou believe that Kiritsugu was the one responsible for the huge fire that killed so many people ten years ago (although this is only half true, as Kotomine was the one who made the wish to make everyone in the area disappear). Following this, Shirou begins to have visions of Saber thanks to his mental link with her. Shirou then decides to come out of hiding and rescue Saber. Kotomine then acknowledges Shirou as Kiritsugu's son and secretly swears to end Shirou's life personally.

Shirou tracks down Caster and Kuzuki only to be beaten by Rin and Archer. During the battle while Rin attempts to reach Kuzuki, and Caster overwhelms Archer until she temporarily retreats upon Archer starting to unleash Unlimited Blade Works. Kuzuki bringing a defeated Rin stops the battle, and Archer is forced to also become Caster's Servant in exchange for Rin's safety. Caster reneges on the promise by ordering Saber to slay Rin, but Shirou saves Rin and takes her to safety just in time.

After the loss of Archer, Shirou and Rin are approached by Lancer, who has come to offer some help. They attack Caster and Kuzuki who have taken over the Church. While initially overwhelmed, Archer, having been waiting for his chance to kill Caster, assassinates both her and Kuzuki before turning his attention to Shirou. Shirou who has become disgusted with Archer, engages Archer demanding why Archer hates him so much, The two are stopped by Rin who manages to convince Archer from killing Shirou by talking it out. Rather than Rin forming a contract with Saber, Shirou manages to become her Master again, while Rin becomes Archer's Master again. It continues to follow the Fate route afterward, Shirou's feelings for Saber continue to develop and her for him as well.

Fate/hollow ataraxiaEdit

Shirou, as Saber's master, is the winner of the Fifth Holy Grail War, having opted to destroy the Grail. Half a year later, he continues to live a peaceful life with the other Servants and Masters in Fuyuki. However, the peace is broken when Heaven's Feel is unexpectedly restarted, despite the destruction of the Grail. Shirou then decides to patrol the town with Saber to investigate the dangers of the restarted war. Shirou soon discovers though that everyone is trapped within a loop of four days, thus resolving to put an end to the loop. In the meantime, He finds himself repeatedly encountering a mysterious silver-haired girl when going out alone at night. However, he is unable to properly interact with her as he is quickly killed by a horde of beast-like shadows, resetting the loop back to the first day. Additionally, Shirou and Saber encounter a new Master and Servant: Bazett Fraga McRemitz and the mysterious Avenger, who are participating in a war unrecognized by the others. Unfortunately, Shirou and Saber are both killed in this encounter, resetting the loop once again.

Shirou learns from Rin, after returning from London, that both the loop and the restarted war may possibly be the result of the Holy Grail granting someone's wish. Later, Shirou encounters the silver-haired girl once again who reveals her name as Caren Hortensia, and that she already knows who Shirou is. However, like the times before, a horde of beast-like shadows attacks, only this time though they are beaten by Shirou and Caren. After defeating the horde, Caren tells Shirou to meet her at the Church to further discuss the situation occurring in Fuyuki. Meeting Caren at the Church, she begins to relay information regarding the loop and the restarted war. Caren reveals that the events occurring within the loop are artificial, though she says the people themselves are real except for one. She also reveals that she was sent to investigate the Holy Grail and the nature of the restarted Heaven's Feel. Furthermore, she tells Shirou that as the winner of the Fifth Holy Grail War only he can end this new war, as it is a reenactment of the fifth so it must end with his victory. Shirou then leaves the church after being told by Caren to ask Rin about London.

Shirou questions Rin about London, to which she eventually reveals the existence of twin manors built during the third war to be used as separate hideouts for the Edelfelt sisters. She further recounts that one of the manors was where she discovered the murder scene of Lancer's original Master. Prompted by this information, Shirou goes to one of the manors to ascertain it as Bazett's hideout. However, he finds the place to be empty, though he does discover one of Lancer's earrings. Taking the earring with him, Shirou goes to the harbor to get Lancer's assistance against Bazett, using the earring to convince him. Agreeing to kill Bazett, Shirou and Lancer meet up at the church courtyard before midnight, where they encounter Bazett and Avenger. Lancer and Bazett confront each other brieflly, which ends with them giving each other fatal wounds with their Noble Phantasms. With Bazett's death Shirou believes that both the loop and the restarted war will now end, though he is surprised that Avenger still exists despite his master being dead. The horde of shades then appears, yet their focus is only on Avenger. Avenger then begins to turn into one of the shades, but he manages to tell Shirou to speak with the Heaven's Cup, imploring Shirou to destroy real him, before his transformation is complete.

Realizing what Avenger may mean, Shirou visits Illya to get answers. She reveals that the Holy Grail that reproduced the war is a true wish granter compared to the Holy Grail of the Einzberns. She further reveals that the Grail is actually Avenger, which is located at the moon. It is also discovered that Shirou is actually Avenger taking his form. Now knowing his true identity, Shirou returns to being Avenger, and with Caren, goes up to the Grail to end the loop. Outside the loop, the real Shirou is tricked into letting Bazett stay at his house.

Carnival PhantasmEdit


Shirou in Carnival Phantasm.

Shirou has a large role in Carnival Phantasm due to being the main character of Fate/stay night. He often interacts with his love interests, and a large plot deals with him attempting to date them simultaneously in order to make all of them happy. It is also shown that, despite what Nasu has stated, he and Shiki Tohno are very good friends and often collude with each other to keep the girls happy.

Today's Menu for Emiya FamilyEdit

  • Young Shirou
  • Shirou's obscured face.

Shirou is the main character of Today's Menu for Emiya Family, which features mostly Shirou (and occasionally, other characters) cooking various Japanese and/or Chinese dishes while explaining how they're made. A young Shirou also makes an appearance in Episode 6.

Shirou's face becomes obscured in episodes that center around Archer, as demonstrated in Episode 11.

Capsule ServantEdit

  • Shirou and G-Sakura ending.
  • Shirou and Celebloomers ending.
  • Shirou and Bazett ending.
  • Shirou and Joan ending.
  • Shirou and TOHSAKA ending.
  • True ending.

In Capsule Servant, he appears in his younger appearance as a playable character. He along with Rin are the two main protagonists that the player can choose. A young Shirou journeys throughout the game encountering and defeating several masters and their arsenals of Capsule Servants.

In one route he battles Jeanne d'Arc, assuming her to be King Arthur, which infuriates her. At the end of that route he summons her instead of Saber 10 years later. She wants to become a cash cow like Saber, which both Shirou and Lancer react by constantly telling her to wait. Another route has him battling Bazett Fraga McRemitz who appears as an apparent temp Heroic Spirit. After Shirou defeats her he promises her that in the next Holy Grail War he'll summon her, which 10 years later keeps his promise with her appearing as "Boxer". In the last route Shirou and Rin both face off against a baby Caren who appears to be the source of all the conflicts. After Shirou and Rin defeat her and take away her powers, Caren decides to fade away which Shirou disagrees with. He informs her to come live with him, stating that he would raise her until she'd grow up stating he'd figure something out with Taiga. She is later adopted by Taiga and raised as Caren Fujimura alongside Shirou.

Other appearancesEdit

In the Fate/Apocrypha universe, the Fourth Holy Grail War didn't occur, Shirou is still living in Fuyuki with his original surname unchanged. His personality is a lot closer to his Capsule Servant counterpart. Still having an honest and upright personality, and likely going through days with a love comedy-like tone, along with a twin-tail magic-fist user and her cheerful little sister who laughs like a high-class young lady.[8]

In the Fate/kaleid liner PRISMA☆ILLYA series, Shirou has two alternate versions of himself: Miyu's brother and Illya's brother.

Shirou makes an appearance in Fate/Grand Order as a Craft Essence card. He appears as the illustration cover for Projection Magecraft (投影魔術, Tōei Majutsu?) and Limited/Zero Over (リミテッド/ゼロオーバー, Rimiteddo Zero Ōbā?). This design is later on used for Sengo Muramasa when he is summoned in Shirou's body.

In Fate/strange fake, Shirou is briefly mentioned when False Caster tells his Master Orlando Reeve that he heard stories of a magus with a talent for Tracing copies of Noble Phantasms. False Caster suggests contacting him to assist them in their future battle with Gilgamesh. Reeve vetoes that suggestion, saying since Shirou's Traced weapons are weaker than the originals, he would not stand a chance against Gate of Babylon.


Shirou is a magus trained by Kiritsugu Emiya. Differing from a formal magus, Shirou can instead be called a Spellcaster who does not follow the normal ways of magi. As he was adopted into the Emiya family, he has no way of inheriting Kiritsugu's Magic Crest, and he lacks the innate talent produced through generations of magi striving to develop the best Magic Circuits. His training was informal, as Kiritsugu had no desire to teach him originally, and aside from sparse knowledge, Kiritsugu taught him nothing of magecraft. He has an Origin of "Sword" and Elemental Affinity of "Sword" as well due to having had Avalon inside him for many years. This leaves him unable to use magic of the five great elements with precision due to lacking any as an alignment, but it does allow for the manifestation of Unlimited Blade Works and the derivative skills in Reinforcement and Projection Magecraft.

Despite any more training, even when following Rin to the Mage's Association, he will never leave the level of a magus apprentice. Should Rin be given a ranking ranging from seventy to one hundred as a magus, Shirou would only rank as a ten. Ranked within the classification as a specialist spellcaster, he would be received as someone on par with Kiritsugu’s evaluation as a "Magus Killer" with a rank of forty.[9]



Structural Grasp Magecraft.

He is an unorthodox magus who makes use of a very specialized version of Projection magecraft. Shirou is initially completely inept as a magus, only able to use Reinforcement and Projection Magecraft with a low level of success. Reinforcement allows him to analyze the structural composition of an object, and increase its effectiveness, such as making it more durable or its shape more practical, or return it to its original state. He can also use it to improve upon the physical capabilities of his own body, such as his eyesight, allowing him to see as far as four kilometers away. Shirou is also very skilled in Structural Grasp Magecraft, which allows him to understand the structure and design of objects as if he were viewing a blueprint. Projection, while a high level skill, is generally considered useless compared to Reinforcement due to the higher magical energy cost, and anything that Shirou initially projects is useless and hollow. Though the objects merely imitate the shape, there are only a few who can identify them as fakes in a first glance. Any practitioner that analyzes composition wouldn't be able to see through them, and even one that works through spiritual mediums would only notice a sense of incongruence. Since only objects with history ever go into the Department of Spiritual Invocation of Clock Tower, there is a low probability of them being discovered. Shirou's structural analysis is not a type of Mystic Eyes.[10]

Shirou is later capable of using Tracing, a higher level version of Projection that completely copies everything regarding the creation and existence of the object. During the Fate scenario, he slowly learns of it on his own by training with Rin and following Archer's advice: "If you can't defeat it, then imagine what can", while in the Unlimited Blade Works scenario, he learns of it through extensive contact with Archer. He is only effectively able to reproduce swords, other weapons, and armor, but this specialty allows him to faithfully reproduce even legendary weapons. However these weapons always suffer some degradation, as Humans cannot conceptualize an object's existence with a single sense. He is capable of reproducing any sword that he has seen, though Noble Phantasms are always one rank below their original strength and armor costs three times the amount of magical energy, and he is capable of employing its entire history, allowing him to wield any weapon with the same proficiency of its original owner. He has to see the weapons as how their form as final product actually are with his own eyes to reproduce them, as even the blueprint of Zelretch is not enough to reproduce it, but by seeing it and Caliburn through shared memories of Justeaze Lizrich von Einzbern and Saber, he becomes able to fully trace them afterward. If the weapon is not made of materials that exist in the world, such as Ea, he cannot analyze or reproduce it, though he can tell its basic nature. He is also quite capable of creating his own original kinds of weapons, should he put his mind to it.


Rin forming a contract with Shirou in Realta Nua

It is later identified that these abilities and Shirou's affinity with swords are concepts of Shirou's Reality Marble, Unlimited Blade Works. Rather than simply creating his projections in the real world, he actually reproduces them within the Reality Marble, as if he were loading a gun, and then projects them into the real world as if he were firing it. This allows him to prepare dozens of swords at a time for later use. Shirou is unable to properly deploy or maintain Unlimited Blade Works due to a shortage of magical energy, but with a proper contract with a magus with a suitable level of magical energy, such as Rin, he is capable of using it. If he were to learn about it normally, unlike the situation in Unlimited Blade Works where he learns of it firsthand from Archer, it would take ten years of training to set the foundations for the ability and another ten years to reach to the point of being able to use it.[11] While actually using Unlimited Blade Works, the cost for creating the weapons is greatly diminished and the speed at which they can be created is also increased, allowing him to easily overwhelm Gilgamesh and his Gate of Babylon.

If Shirou were to fight Shiki Tohno, there would be a high probability of a mutual defeat where Shirou would have his projected Noble Phantasms one-sidedly killed, while Shiki would overuse his Mystic Eyes of Death Perception to the point were he would overload and self-destruct after the battle. Circumstances would change if Shirou were capable of an Excalibur-like magical energy discharge. During a fight with Bazett Fraga McRemitz, a professional that specializes in anti-magus combat, he would likely be overwhelmed by her techniques, experience, and tactics, and he would also constantly have the disadvantage that using any of his high level techniques would leave him susceptible to Fragarach's instant kill ability.[12]


Shirou's basic training in Magecraft was extremely lacking, so he was left with the idea that he needs to create a new Magic Circuit with each use of Magecraft. He goes through extremely dangerous training, which he describes as the feeling of inserting a hot iron rod into his spine, where he constantly faces the risk of death in order to develop a new Circuit. Though his body has twenty-seven natural Magic Circuits, they had been abandoned for his nerves, which he made into makeshift Magic Circuits due to his wrong method of training. Once his real Circuits are awakened, he goes through extreme pain and suffering as his nervous system gets used to the new intake of energy. His newly opened Magic Circuits can barely handle ten units of magical energy each.

Shirou has Avalon implanted within his body, which saved his life during the great fire. This gives him an extremely potent regenerative ability while Saber is summoned due to Excalibur, though it does seem to sustain him even without it as he was able to temporarily survive a fatal blow dealt by Lancer. This allows him to survive numerous fatal wounds though it works against him in bad endings where he is able to be tortured and mutilated without succumbing to his injuries for a long duration of time. Unlimited Blade Works also seems to protect Shirou by creating blades within his body to reinforce it. He is able to survive a blow to the chest from Rider's dagger, which is repelled as if it is hitting metal, a kick that would have gouged his stomach only knocks him away, and he manages to keep from having his entire body destroyed from an attack by Gilgamesh. The ability seems to go out of control during a bad ending where numerous swords sprout from his dying body, and while his body is fully breaking down in the Heaven's Feel scenario, they are constantly being created and protruding from his skin. This allows him to damage Kotomine whenever Kotomine hits him even though his "body of swords" still cannot defend against the Bajiquan attacks of Kirei. He practices basic sword fighting with Saber, though it amounts to little in actual offensive capabilities. While she teaches him, he cannot use her fighting style as a model. He cannot see exactly how she is attacking and their different physiques makes her impossible to copy.


During Fate, Shirou only learns the basics of his abilities, leading him to only trace Caliburn and Avalon.


Shirou's Bow

He temporarily utilizes a bow during the second battle with Berserker, having imitated Archer's Bow. Shirou’s Bow (士郎の弓, Shirō no Yumi?) is formed by utilizing strengthening magecraft on a tree branch he had found, and he creates arrows for it in the same manner. It utilizes the same design for the most part, but the arrow rest and grip are amateurish and simple compared to those of Archer's bow. Shirou personally thinks it is ugly and crooked, but it functions properly as a bow. It is also slightly less curved due to Shirou's preference in the Japanese method of shooting. He is only a practitioner of Japanese archery compared to Archer's Western method, so he subconsciously altered the bow into his preferred shape without realizing it.[13]

Unlimited Blade WorksEdit


Shirou and Archer's connection is a large part of his development in the Unlimited Blade Works scenario. The contradiction of Shirou Emiya and the Heroic Spirit EMIYA existing at once is much like magecraft that allows one to acquire skills from the past by possessing themselves with a previous self. The more they come into contact, the more of his knowledge and techniques flow into him. The abilities suit him perfectly, as they are Shirou Emiya's optimal technique, perfected over many years of training.

It is first noticed after several training sessions with Saber, when he makes a drastic improvement over the previous day. Copying Archer's technique, he begins to make fewer unnecessary movements, allowing him to desperately avoid her counter-attacks rather than become instantly knocked out, and as his body is already fit, just the knowledge of proper techniques can improve his fighting quickly.

He is captivated by Kanshou and Bakuya, and uses it as a basis for a two-sword fighting style. He does not have a basic style, so it is immediately evident that he is copying Archer. The flow of it is so unconscious that he believes that Saber is going easier on him, and his sword is able to automatically parry her strikes even though his body cannot react to them.

The effect greatly magnifies after they recognize each other's identities, causing extreme pain as it flows into him. His body begins to break every time they touch, as he has learned too much of his future self while trying to match him in skill. He even begins to obtain Archer's memories, such as the reason behind his hatred for their shared ideals. He is hardly capable of competing with Archer even with their connection strengthening him and only once he has passed his limits is he able to take on Archer on what could be called nearly equal grounds, with Archer being perplexed at how the gap between their skills was quickly closed, and even eventually defeat him with his "passion-infused strike", unperceivable even to Archer's Eye of Mind.


Once he learns the true use of Projection, he lacks proper training so even the most basic projections cause him pain and the majority of the swords generated shatter upon impact due to their low quality. He projects both Archer's sword technique and his reproduction ability, but it is flawed because he does not understand that they originate from his Reality Marble. Unlimited Blade Works cannot be utilized without that realization, and even after coming to that conclusion, he does not have the necessary energy to utilize it on his own.

He forms a contract with Rin to have her provide the necessary magical energy to form his Reality Marble. This grants him the ability to finally make use of Projection in battle, allowing him to quickly trace the weapons from the Gate of Babylon while fighting Gilgamesh to duplicate them well enough to counter his barrage of weapons, which Gilgamesh praised him somewhat for. Upon actually utilizing Unlimited Blade Works, Shirou used the fact that although Gilgamesh wields countless weapons, he has not mastered them all and his greatly increased reproduction speed and constantly ready weapons while in his Reality Marble to completely overwhelm and defeat him. However, he stated that he would not stand a chance against other Servants who had mastered their weapons to their utmost limit, the ability being only slightly challenging for the likes of them.

Heaven's FeelEdit

Archer's armEdit

Shirou does not develop his abilities as he does in the other routes during Heaven's Feel. He uses his basic Reinforcement magecraft on a stick and wooden sword during the early part of the war without grasping onto Projection. During the first conflict in the Einzbern Forest, he loses his arm while protecting Illya from the Shadow's explosion. The wound is critical, so Archer, having also suffered a critical wound, tells them to transplant his left arm onto Shirou. Attaching a spiritual body to a normal human body requires a spiritual doctor like Kotomine because the process it more akin to healing the soul rather than the body.

Kotomine manages to attach Archer's arm (アーチャーの腕, Āchā no Ude?) to replace Shirou's lost arm. It is a "foreign substance" that should not be there, attached by opposing the natural Providence, and joining two separate spiritual bodies is forbidden magic that cannot normally succeed. The formation of spiritual bodies deals with resurrection and restoration of souls, divine mysteries that cannot be handled with magecraft, so it would normally be that the recipient would die of shock even if the operation was a success in shape. Kotomine expected the completion of the surgery to result in his death, but Archer and Shirou being the same person makes them an exception to the normal rejection. Not knowing of their exact connection, he states that they are suited for each other and not even two twins would be as similar.

While the arm would have disappeared had Archer faded away while the surgery was in progress, it is now anchored to Shirou and can be called his own limb. Due to being transplanted while Archer was still in the world, it is part of a Heroic Spirit that has been connected to his Magic Circuits, and stays in the world using his own magical energy. While unconscious, the arm grants him knowledge on Archer, the basis of Projection magecraft, battle experience, and battle information. The sensation feels like his body is burning while countless ants enter the hole in his shoulder that is now sealed with flesh that is not his own. While the sensation tells him to manage these skills, the level of information and power required feel impossible to him. Even if it becomes familiar with his body, he neither has the skills to handle it or the power to use it without destroying his body.

While they are the same person with compatible Magic Circuits, the power of the arm of a Heroic Spirit is not something a human can handle. No matter how suited he is to the arm, he cannot use its abilities without it eventually swallowing him due to his body being spiritually far inferior to the arm. It can be considered a weapon more than an arm, and it is referred to as an Artificial Phantasm: Man-made illusions (アーティフィシャル・ファンタズム
, Ātifisharu Fantazumu
Jinkōtekina Gensō
?) in the scene's title. It passively flows Archer's battle experience and physical abilities into Shirou even while inactive. It acts like an overdose of strength-enhancing drugs, letting him demonstrate abilities beyond his limits.

He becomes able to easily leap out of the third story window of the Einzbern Castle, compared to around eight stories for a normal building, with only temporary numbness and pain upon landing. Unable to strengthen his body, he does bring a large amount of magical energy to his feet to lessen the impact and believes that landing on asphalt instead of grass would have broken his legs. Illya mentions that Archer is influencing both his mind and body, making him think that he can easily handle the drop like Archer and toughening his body enough to survive. He can also run fifty kilometers per hour through the uneven terrain of the Einzbern Forest.

Shroud of MartinEdit


Shroud of Martin

In order to counteract the effects of the arm, Shirou is given a Holy Shroud, the Shroud of Martin (マルティーンの聖骸布, Marutin no Seigaifu?), by Kotomine, as a seal which keeps Archer's circuits from connecting to his body because it has the ability to seal a certain event or return it to normal.[14] It completely wraps around his arm with the exception of his fingers, and while it is initially completely numb, it eventually regains enough functionality after familiarizing with his body to allow him to lead an ordinary life. It would be possible to cut it off, but that would remove his only possible weapon in defeating Zouken.

The arm is treated as a different object even if he uses magecraft, but magical energy still constantly flows through the body even if magecraft is not being used. Despite the Shroud cutting off the Magic Circuits, he will feel a great deal of pain if he does not concentrate to form a "barrier" to keep the "foreign substance" out of his unstable body when the arm reacts to the energy and tries to activate. It is easy to do once he figures out where the pain is coming from, and he is able to control it to an extent. Living with it is not quite as easy as Kotomine suggests because the arm randomly flows magical energy into his body. It constantly becomes hotter each time he moves it, and when it overheats, it sends the excess to the rest of his body.

While it first feels like he is being burned, he realizes it is more like he is being cut and stabbed by his own body. Simply undoing part of the binding for even a brief moment causes him to completely lose himself as his nerves and senses are overwhelmed by extreme pain and the feeling of impending death. He rambles on in his mind about how he is feeling more pain than ever before, "sitting on a mountain of swords", and that he can see all of his cells crumbling apart. He regains his senses a few seconds afterward, and he cannot remember the exact happenings during that period. Although he can manage at times, he still suffers a great deal of pain in intervals to the point of wishing to simply cut it off, or even risk removing the shroud to stop the pain. Its existence brings him true fear of an unavoidable death and utter obliteration, making it the first he has felt such since the fire ten years before. His ability to suppress the infringement from the arm even with the Shroud is limited to a certain extent, with Kotomine noting that the arm will consume him within ten years, but the Shroud is still able to hold it long enough to make it not an imminent threat and give Shirou time to train himself to become a magus worthy of matching the arm to seal it without the Shroud to allow him to live to an old age.

Rin also shares part of her Magic Crest with him as a Warding Sign. She is able to transplant a small part of her Crest by placing her left hand on his body, comprehending it, and sharing her warding crest. While she was planning on giving him the capability to use a "switch" for his Magic Circuit, being able to turn it on and off is too dangerous in his current state. She instead performs it to suppress the magical energy by placing needles in his left shoulder, belly button, and throat so that the arm won't be connected to him unless he wishes for it. It also grants a resistance to magical energy, so that something that passively absorbs energy like the Shadow will have less of an effect on him. Her crest cannot familiarize itself with someone not from the Tohsaka family, so it is a makeshift that won't even last a week.


Shirou is currently observing Archer's magecraft rather than his own magecraft, so he cannot use Projection in his current state without invoking the abilities of the arm. Illya states that he will eventually obtain his own usage of Projection magecraft, but it is still only a possibility at his current level. His own Projection is still at the level where it will fail constantly due to his misunderstandings, but drawing on Archer's knowledge without invoking the arm can force him to "level up" quickly. He can loosen the Shroud slightly in order to practice retrieving Archer's knowledge without breaking the seal and only getting a small reaction.

With help from Rin's Magic Crest to increase his Magic Resistance and Illya to protect his consciousness, he can experience Archer's Projection by interacting with the arm like opening a Magic Circuit safely. The knowledge is like poison, but the arm will continuously flow its experience into him. It is similar to pouring one hundred units of fuel into a container that can only hold ten, and he will likely only gain from less than a tenth of the agony he will endure. The knowledge disrupts his memories and leaves him with a large blank space after replacing the Shroud.

Projecting directly with Archer's abilities requires the removal of the Shroud, and although potentially able to recall the activation spell gained from Archer's knowledge, his body would be destroyed if he tried using it. It can easily be removed at any time for instant access to the full extent of Archer's power. It is not something that lessens his life with each use, but the activation of a time bomb that will ultimately lead to his death the second he removes the Shroud. Archer's Magic Circuits will be activated if he uses the arm even once, and while he may last while using its abilities, his body will break down due to being unable to withstand Archer's magic. He will eventually be consumed, or more correctly "blown away", by the arm after the first activation.

Once it is removed, Shirou instantly gains access to Archer's Magic Circuits, battle experience, and techniques, making him capable of matching and potentially even defeating Servants in direct combat, but he cannot deploy Unlimited Blade Works because Archer's inner world is different from his. While claiming he can only reproduce what he himself has learned and the Noble Phantasms that he has personally recorded, he is revealed to be quite capable of using Archer's records to project weapons he had never personally witnessed before, as he was able to project Caladbolg II and Rho Aias. He is able to trace "Nine Lives" to kill Black Berserker nine times with a single maneuver called "Nine Lives Blade Works" and later defeat Saber Alter with the Overedge technique of Kanshou and Bakuya at the cost of his mind during a bad ending. Using these abilities comes with a heavy penalty as Archer's circuits overload Shirou's body leading to his mind slowly eroding, the decay of his memories, and eventual death as his body and soul break down from being invaded by Archer's Unlimited Blade Works.

Puppet bodyEdit

Due to Archer's arm and his overuse of Projection, his Magic Circuit is broken into pieces, and his death is one that even the Holy Grail could not reverse. He is resurrected by Illya's imperfect usage of the Third Magic, reviving his soul and giving him a body free of wounds by preserving his soul and inserting it into a container. It would normally be that giving the soul a container or body would allow it to take perfect form by utilizing the "genes of the soul" rather than those of the body. His body is reconstructed from a portion of Illya's body, which she mentions is a bit cheap as a container, so it is nowhere near his original form in terms of size. Its shape afterward is not that of a human, but as he mentions reaching his hands out and grasping onto Rin's pendant, it is at least vaguely humanoid. He is able to be found due to Rider using the pendant as a landmark to locate him, and while his exact form is left unknown, it is small enough to be "plucked" from the river by Rider.[15]

He is not a true product of the Third Magic, a high-dimensional planar being, but it instead re-anchored his soul to a vessel. They decide to experiment with various ideas for a proper body during the first six months, as he cannot simply grow in his current state. They do not have the resources to make a homunculus body, so they instead sell the books of the Matou household to obtain a puppet body left by Touko Aozaki. He is perfectly human even in this state, but Rin notes his soul is actually remotely controlling the body. He can receive surgery at hospitals, drink cold medicines, be killed, and eventually grow old and die of old age. The soul is fixed to the body, so he can be likened to a Servant that can operate without a Master.

He has some issues because the body is used, but even other good puppet makers cannot match up to it. Rin wishes to find and consult Touko about it, but her Sealing Designation makes that a hard prospect. The magical energy does not flow well, but Shirou is fine with it because all other aspects are better than his original body. The soul will overwrite the body no matter its quality, so there will likely always be places that won't function properly. Sakura supplements his very weak Magic Circuit with her own overflowing amount in order to keep him from returning to his prior state. Despite the setbacks, Rin believes that he should be able to utilize Unlimited Blade Works with training, and that his being a successful example of the Third Magic is an extraordinary trait in itself.


Creation and ConceptionEdit

Kinoko Nasu's original story of Fate, Saber and Shirou were opposite gender to now. Ayaka Sajyou was the original main protagonist until Takashi Takeuchi convinced to Nasu to change the setting but the essential theme had not been changed, it's the story about legendary heroes and "a boy meets a girl."

Nasu describes his writing of Shirou is based on novels written after the 90s, where the main character suffers from trying to come to terms with his problems in their own narrow perspectives.[16]

Potential RoutesEdit

In the original concept there were three additional routes that were meant to be implemented for Shirou each with different heroines, but were never implemented due to time constraints on the title release. A Rider route (though this could be considered to have been followed by Fate/Hollow Ataraxia), a Caster route, and the implementation of a new character a Tachie route (Tachie was an original character that was from Shirou's past, and a prototype to Mashu Kyrieliete from Fate/Grand Order. She was an attempted inclusion in the 2006 Anime and the 2010 Movie as well but was never fully implemented.) 


Gen Urobuchi believes Saber's relationship with Shirou doesn't seem like a realistic relationship between a male and a female, but a complicated relationship with a boy who became a girl. He further explains that it is not a relationship fueled by instinct like the relationship between a man and a woman, but a romance of logic between two people who need each other from the heart. He thinks the Fate route could have been told as a story through the ancient Greek views on love. Urobuchi, thinks the true heroine of Fate/stay night is Rin Tohsaka. He asserted that Shirou's relationship with Rin was the more realistic relationship. In the "Unlimited Blade Works" route, an equal relationship with a woman who's become stronger than men is depicted. Rin and Shirou mend each other's weaknesses with their own unique strength. Also, Sakura's romance expresses the dark sides that women have, but Shirou's actions show that men can accept that and love them regardless.[16]

Takeuchi has stated that Fate/Grand Order's main protagonist Ritsuka Fujimaru is based on genderbent versions of Shriou Emiya and Rin Tohsaka.
