Antecedentes

Diez años antes del comienzo de Fate/stay night, Shirou era un chico ordinario viviendo con sus padres en Shinto. El gran incendio causado por el deseo de Kotomine al final de la cuarta Guerra del Santo Grial mató a ambos de sus padres y lo dejó mortalmente herido dentro del fuego. Fué encontrado por Emiya Kiritsugu, quien estaba descorazonado luego de los eventos de la guerra, y deseando compensar de alguna manera sus acciones, salvó la vida de Shirou al incrustar Avalon en su cuerpo. Mas adelante le preguntó a Shirou, que aún estaba recuperandose, si querria ser su hijo adoptivo, revelando por completo su identidad como un mago. Shirou aceptó y ocupó los siguientes 2 años pidiéndole persistentemente a Kiritsugu que le enseñara su magia. Kiritsugu finalmente aceptó, y a pesar que no aprovaba el deseo de Shirou de aprender su arte, le aconsejó aplicarlo en secreto, donde podria beneficiar a la gente sin atraer confusión o sospecha. El conocimiento que le transimitió a Shirou fué muy básico e incompleto, guiándole por una senda pelicrosa con resultados pobres. Además, y posiblemente sin darse cuenta, Kiritsugu le heredó a Shirou su filosofia de desear ser un "heroe de la justicia" capaz de salvar a quien sea.

Several years before the fifth Holy Grail War, Kiritsugu suddenly died, leaving Shirou frustrated, depressed, and alone. He was subsequently watched over by Fujimura Taiga, Shirou's longtime neighbour and his English teacher, and his living expenses were managed by her grandfather, Fujimura Raiga. 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 accordingly 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 actually does a pretty good job.” and started to laugh.

After starting in Homurabara School, he met Ryuudou Issei and became known as someone who would do anything to help others, such as fixing the school equipment. He later joined the Archery Club, which led him to becoming estranged 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 smoothed out, but some tension remained, especially in regard with Shinji's treatment of Sakura. Shirou also became closer to Sakura, as she started to frequently visit his household during the period while he was injured in order to help him cook and clean, and even after he was healed, she continued to come as a member of his makeshift family.


Hobbies

Shirou possesses an extraordinary talent for housework. Despite having Taiga as his caretaker, he generally provides all of her meals and does 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 is better with Japanese tea, and he he 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 among 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 fiances taken care of by Raiga, Shirou doesn't wish to feel like a freeloader, so he has been working part time jobs during since middle school in order to pay for his own expenses.

Shirou does not feel good 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 is poor and his intended major is initially in the field of laws and politics. He has a small collection of pornography acquired through his part-time job that he hides behind an album of photos set by Matou Shinji, which were not intended to serve as camouflage. He likes fixing up 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 “Homurabara’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 Himuro Kane, Sajyou Ayaka and Mitsuzuri Ayako, Issei caused a quarrel after being harassed with concentrated attacks and made both teams be disqualified.


Personality

Due to the trauma suffered during the great fire, Shirou has a constant emptiness in his personality. He feels that as the only survivor that it is unfair to the deceased to prioritize his own needs before those of others. He has a distorted sense of values where he finds selfworth from helping people without any compensation, as he feels that the very act “helping people” is his reward.[1] 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 viewpoints. 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.

Shirou takes his ideals to the 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 multiple times more powerful than him. He cannot see her as anything but a woman who needs protection, much to her own annoyance. 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 sticking to his ideals and saving the life of Sakura, who he loves. He eventually gives them up, with the exception of the "Mind of Steel" ending, where he becomes as resolute as Kiritsugu in his prime, allowing Sakura to die. 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 wills simply watch instead of helping. Nasu has stated that Shirou and Tohno Shiki would definitely get along badly.


Rol


Fate/stay night

Shirou 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 fire will never occur again.

In Heaven's Feel, Shirou body was completely dead to the point that even the Holy Grail could not restore it, but Illyasviel von Einzbern resurrected his soul with an imperfect Third Magic and revived him by giving him nothing else but a basic body. This is not like pouring a spiritual body and consciousness into the brain of another to manipulate it, but a materialized soul that possess human functions which was given a body by the Third Magic. By giving a body to the soul, the flesh is perfectly reproduced after the shape of the soul. However, because Illyasviel Third Magic was imperfect it took half a year was of continuous trial and error, but in the end a basic body made by Aozaki Touko was purchased with the money from selling the books of the Matou family to the Mage’s Association and things were settled for the time being.

But even in this state where the soul operates the body by remote control while remaining inviolable in the other world, it still does not mean that he is immortal, as he can grow old, still has a lifespan and will die if killed. But the soul cannot remain in this world without the body, because instead of the soul reproducing the body that is dwelling in, it is being fixed by that body. In short is a like the state of a dead Servant that can take action without a Master and is living in the same way as a human being.

However, because Aozaki Tohko had less Magic Circuits than Shirou, the transference of prana is bad. It seems that in this state, the strong point about Shirou’s basic body is that because it was repainted by the soul the original one became ordinary, but the flaws of the original were retained as they were.


Fate/hollow ataraxia

The Shirou present in the game turns out to be a facet of the illusion created by Avenger to satisfy Bazett's wish to keep on living. Avenger takes on Shirou's persona during the daytime of the four-day temporal loop, where he has no knowledge of his existence as Avenger. He explains it as Avenger himself equaling "zero", and no matter how much "zero" is added to "one", it still only equals "one." As Shirou, he comes to care for other people, especially the mysterious Caren Ortensia. Eventually, Shirou realizes the existence of the temporal loop, which leads to him attempt to resolve it. The main problem is that Avenger enjoys his daily life as Shirou so much that he doesn't wish for it to end. Caren, who Shirou never meets due to dying whenever they come across each other, reveals to Shirou and Avenger that they are one and the same, and that he is the cause of the loop. Much to Bazett's sorrow, Avenger decides to put an end to the loop and returns to the void of the Grail.


Abilidades


Combate

Shirou is initially completely inept as a magus, only able to use Reinforcement and Projection Magecraft with a low level of success. Reinforment 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 prana 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 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. 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 prana, 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 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 Lizleihi Justica 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.

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 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 prana, but with a proper contract with a magus with a suitable level of prana, 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 reach to reach the the point of being able to use it. 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 Tohno Shiki, 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 prana 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.


Conocimientos

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 have been abandoned for his nerves, which have become makeshift Magic Circuits due to his 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. This leaves him with weak Circuits that can barely handle ten units of prana each. Shirou will never leave the level of a magus apprentice, compared to Rin classified as an "100", Shirou would be a "10", but as a specialist spellcaster, he would be received as someone on par with Kiritsugu’s evaluation as a “Magus Killer”, where he would be classified as a "40" compared to Rin's "100."

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 to due 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.

During Fate, Shirou only learns the basics of his abilities, leading him to only trace Caliburn and Avalon. He practices basic swordfighting with Saber, though it amounts to little in actual offensive capabilities. He gains a much greater understanding in Unlimited Blade Works, as extensive contact with Archer, who is essentially the same person, allows for Archer's combat and Magecraft techniques flow into Shirou. He develops an affinity for using Kanshou & Bakuya and Archer's fighting style, which Saber notes while they are training. 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 forms a contract with Rin to have her provide the necessary prana to form his Reality Marble, and he manages to project a number of weapons from the Gate of Babylon in order to defeat Gilgamesh.

Shirou loses his arm during in the Einzbern forest in Heaven's Feel, and as he requires a transplant to survive, he is granted Archer's arm. Normally when attaching a part of a spiritual body to a person, referred to as an "Artificial Phantasm", results in death after the completion of the surgery. Shirou manages to survive only because he is the same person as Archer, but it would still be impossible for him to handle Archer's power without killing himself. He is given the "Shroud of Martin" by Kotomine, which keeps Archer's circuits from connecting to his body. This is only temporary, and the protection offered by the shroud would eventually wear away after ten years. Once it is removed, Shirou instantly gains access to Archer's Magic Circuits, battle experience, and techniques, though he cannot deploy Unlimited Blade Works due to the drastic change in his own inner world by giving up on his ideal of being a hero of justice. He becomes able to easily leap out of a three story building and run fifty kilometers per hour through a forest. He is also 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 an Overedge technique of Kanshou & Bakuya at the cost of his mind during a bad ending. Using these abilities comes with a great cost, 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.

Historia

Fate/Stay Night, realta el periodo de dos semanas en la vida de Shirou Emiya, un mecánico novato que atiende a la escuela Homurabara Gakuen en Ciudad Fuyuki. Hace 10 años, Shirou fué atrapado en un incendio massivo que incineró a sus padres y consumió una gran porción de la ciudad, mientras estaba muriendo, un hombre enigmático lo descubre y lo cura. Este hombre, Kiritsugu Emiya, decide adoptarlo, a pesar de que los dos mantienen una relación distante debido a  los frecuentes viajes de Kiritsugu fuera de Ciudad Fuyuki. Una noche iluminada por la luna, Kiritsugu y Shirou tienen una conversación afuera de su casa, y Shirou descubre el hecho de que su padre adoptivo era en realidad un mago.

A lo largo de la conversación, Shirou aprende que la ambición fallida de su padre adoptivo es la de convertirse en un "Heroe de la Justicia" (正義の味方, Seigi no Mikata?), un guardian de la humanidad que es capaz de proteger al débil y al inocente. Conmovido por la convicción de Kiritsugu, Shirou le afirma a su padre adoptivo que el pretende comprometer su vida a lograr el distante ideal, muy a pesar del desagrado de Kiritsugu. Para hacer esto, Shirou le implora a un inconforme Kiritsugu el enseñarle hechiceria (魔術, Majutsu?); pero habiendo nacido sin las capacidades de un mago, Shirou prueba no tener talento en casi todas las disciplinas fundamentales de la hechiceria.

Kiritsugu le advierte a su hijo que la vida de un hechicero es una que lleva a la destrucción, pero que si realmente esta decidido a beneficiar a la gente, he deberia aplicar su conocimiento en secreto y pulir su habilidad en privado. Luego de que Kiritsugu muere, Shirou se frustra con su progreso, sintiendose inadecuado acerca de sus buenas acciones a través de la hechiceria y se vuelve inseguro de cómo orientar su futuro a contribuir más.

Sin que Shirou lo sepa, Ciudad Fuyuki es el escenario para una secreta y violenta guerra entre los magos participantes. Por los dos siglos pasados, siete hechiceros se han reunido y encontrado en un gran combate, cada uno apostando su propia vida para obtener el Santo Grial, un cáliz legendario capaz de conceder deseos. Las cuatro guerras pasadas, han ocurrido típicamente cada sesenta años, con la mas reciente concluyendo hace una década, pero la quinta ha iniciado prematuramente.

Cada uno de los hechiceros, mejor conocidos como "Masters", es ayudado por uno de los siete espíritus familiares conocidos como "Servants", que son la reencarnación de almas legendarias a lo largo del tiempo. Estos Espíritus Épicos (英霊, Eirei?) resucitados, poseen características superhumanas y empuñan poderosos artefactos o habilidades conocidas como "Noble Phantasm"(宝具, Hōgu?). La habilidad escondida de un Noble Phantasm puede ser liberada convocando su verdadero nombre, pero el uso inadecuado de un Noble Phantasm es mejor evitado, pues Noble Phantasm simbólicos por lo general revelan la identidad de un Servant, disminuyendo la ventaja competitiva de dicho Servant. Leyendas específicas pueden ser convocadas con la ayuda de catalizadores, los cuales son artefactos, ideas, o experiencias similares o de valor para el Servant deseado. Sólo puede ser convocado un Servant de cada una de las 7 clases en cada guerra: Saber, Archer, Lancer, Berserker, Rider, Assassin y Caster.

Como sólo las emtidades astrales (ejemplo: los Servants) son físicamente capaces de conseguir el Santo Grial, el Master y Servant son forzados a cooperar. Los Masters controlan a los Servants con 3 "Hechizos de Mando" (令呪, Reiju?), los cuales son milagros cristalizados emitidos por el Santo Grial que se manifiesta en el cuerpo de un Master. Al activarse, los Hechizos de Mando le permiten a un Servant acompletar una hazaña increible, o alternativamente proveen a los Masters con la autoridad para expedir una orden irrevocable y absoluta al Servant. Cuando los 3 Hechizos de Mando son usados, los Servants no permanecen obligados a servir a sus Masters, y como tal, pueden elegir libremente rebelarse a su ex-compañero. En el evento del fin de un Master, un Servant puede escojer atarse a si mismo/a a otro Master ; si el Servant es eliminado, un Master puede aliarse con un Servant independiente o buscar santuario con el supervisor imparcial de la Guerra del Santo Grial, el cual es tradicionalmente un delegado de la Iglesia Católica Romana.

El Santo Grial se materializa por completo, sólo cuando queda un único Servant en pie; por lo tanto no es necesario eliminar a los Masters para ganar la guerra. Sin embargo, como muchos Servants poseen poderosos Noble Phantasms y son difíciles de derrotar, muchos participantes han elegido eliminar a los Masters en su lugar, los cuales son responsables de mantener la presencia de un Servant a través de la provisión de Mana.

Luego de limpiar el dojo de arqueria de su escuela hasta tarde una noche, Shirou tropieza con dos Servants, Archer y Lancer, combatiendo en el patio de la escuela. Para evitar comprometer el secretismo de la guerra, Lancer persigue y perfora a Shirou en el corazón con su lanza. Shirou es entonces descubierto al borde de la muerte por Rin Tohsaka y ella usa una reliquia familiar llena con magia concentrada, Mana (魔力, Maryoku?), para restaurar su corazón dañado y se va antes de que el despierte. Sacudido y aturdido, Shirou toma la reliquia y regresa a casa solo para ser asaltado una segunda vez por Lancer. Shirou se defiende débilmente de Lancer usando posters que convierte en metal con magia de refuerzo, pero es rápidamente abrumado por el poder del ataque del Servant, y es lanzado hasta su cobertizo. Arrinconado, Shirou se prepara para lo peor; pero antes de que Lancer pueda infligir otra herida mortal, una marca mágica empieza a brillar en la mano de Shirou y un círculo de convocación usado previamente por su padre adoptivo dentro del cobertizo empieza a brillar. Una joven mujer vestida en armadura con una espada invisible es convocada y bloquea el ataque de Lancer.
Después de repeler a Lancer lejos de Shirou, ella se presenta a sí misma como "Servant Saber".

Terminologia

Como algunos sabrán, los términos usados en el Nasuverso(tal y como se le conoce al universo creado por Kinoko Nasu, creador de nuestra amada serie), son algo difíciles de traducir a nuestro idioma por lo que algunos términos se dejarán tal y como los dice el creador y algunos otros se traducirán de la manera que creamos mejor posible(Existe mucha controversia en cuanto a las traducciones de muchos de los términos, pero aquí pondremos los que tengan mayor aceptación).

Antes de pasar a los términos principales, cabe hacer énfasis en dos términos similares que tienen diferente uso en el Nasuverso:

Magia: (魔術, Majutsu): El arte de usar magia. Todo aprendiz se le considera magos(Magi en ingles) e incluso algunos de los mas avanzados siguen siendo considerados como magos. La magia son acciones que desafian la lógica pero son cosas que se pueden lograr con el tiempo y entrenamiento adecuados.

Hechiceria: Un nivel mucho mayor de magia. Son muy pocos los magos capaces de llegar a usar la hechiceria (siendo denominados entonces como hechiceros, en ocasiones se les da incluso un sobrenombre), al grado de considerarse milagros en lugar de magia(un Reality Marble entra dentro de este rango) ya que desafian la realidad y no se pueden lograr con tiempo y entrenamiento.

La siguiente parte es tomada de wikipedia:

Master: Son los siete magos escogidos para la Guerra del Santo Grial. Ellos poseen una cantidad determinada de poder mágico o maná (魔力, Maryoku?), que debe de usarse para abastecer de energía a su Servant. Los Servants pueden ser controlados por medio de tres Hechizos de mando (令呪, Reiju?) que el Grial reparte entre los Masters, y que se manifiestan como símbolos tatuados en la mano del mago. Cada reiju permite, cuando se activa, dar una orden irrevocable (y que el Servant no puede negarse a obedecer) o realizar una hazaña increíble. Si el Master gastara todos sus reiju o simplemente muriera, su Servant puede elegir entre aliarse con otro Master o buscar refugio con el supervisor imparcial de la lucha, que tradicionalmente es un delegado de la Iglesia.

Servant: Reencarnaciones de almas legendarias (héroes, semidioses, etc) que pueden provenir de cualquier línea de tiempo. Esta clase de seres, además de sus extraordinarias habilidades, son los portadores de los Noble Phantasms, que es aquel poder característico del Servant y su arma más letal. Ellos participan en la lucha con el único objetivo de cumplir un deseo de su anterior vida, por tanto, si gana, el Grial le pertenecerá a él y a su Master. Sólo un Servant de cada raza puede ser invocado en la lucha; éstas son: Saber, Archer, Lancer, Berserker, Rider, Assassin y Caster.

Santo Grial (聖杯, Seihai?): Es una reliquia sagrada que concede cualquier deseo a los que logren llegar hasta ella. Los únicos capaces de tocarla son los Servants, pero éstos no pueden usar sus poderes sin un Master, y es debido a esa restricción que Master y Servant se verán obligados a pelear codo con codo. Pasado un tiempo del inicio de la lucha, el Grial aparece por sí solo, independientemente del número de participantes que queden. Sin embargo, el Grial aceptará como sus dueños a quienes él crea merecedores; puede darse el caso que un equipo gane la guerra haciendo trampas y esquivando combates, y el Grial no los reconozca como los verdaderos campeones.

Noble Phantasms (宝具, Hōgu?): Son reliquias o habilidades con un increíble potencial mágico. El poder interno de un Noble Phantasm puede ser invocado al pronunciar su verdadero nombre, no obstante, los Noble Phantasms famosos usualmente delatan la verdadera identidad del Servant, disminuyendo la ventaja en combate que supone que el enemigo desconozca la identidad de su adversario.

Reality Marble (固有結界, Koyuu Kekkai?): Habilidad extremadamente poderosa que muy pocos Servant pueden llegar a ejecutar. Permite al usuario generar una realidad o dimensión con nuevas reglas y leyes que se utiliza como campo de batalla, de forma que le dé ventajas sobre su oponente; el ejemplo más claro es el "Unlimited Blade Works" de Archer.

De aquí en adelante, la terminología va por nuestra cuenta:
