Kiritsugu Emiya

Kiritsugu Emiya is the father of Illyasviel von Einzbern and Shirou Emiya. He has a minor role in Fate/stay night and is the protagonist of the novel prequel Fate/Zero. He was a freelancer and infamously known as the Magus Killer.

Early years
Born November 11th, 1965 in Fuyuki City, Kiritsugu was raised on Alimango Island, where he lived with his father Emiya Noritaka, fourth family head of the Emiya family and a magus who received a Sealing Designation. He became friends with - and had a crush on - Noritaka's assistant, a local girl called Shirley who was four years older than him. However, disaster struck when Shirley became a vampire after she drank a potion, intending for it to prove that Noritaka's research would save the world, and pled for Kiritsugu to kill her but he refused and fled. Their village is overrun by Executors from the Church and Enforcers from the Association, both groups having arrived when they heard rumors of a magus researching into vampirism. Kiritsugu was the only survivor of the 'cleansing', saved by Natalia Kaminski, a freelancer and part-time Enforcer who wanted information on the magus responsible.

Returning to the hidden Emiya residence, Kiritsugu confronted his father on his research and Shirley's death. Noritaka explained that he wanted to become a Dead Apostle to continue with his research on Magecraft longer. In the Fate/Zero novel version, just as Noritaka was planning their escape, Kiritsugu shot him in the back with a pistol, but in the animated version Noritaka was first stabbed by the dagger Kiritsugu received from Shirley and then shot to death with a pistol Kiritsugu found in Noritaka's drawer. To this end, Natalia figured that the only person who could prevent Noritaka from escaping and ensure his death was his own son and she wound up taking Kiritsugu with her.

Magus Killer
Realizing that the tragedies he saw in his childhood were common occurrences in the world, the teenage Kiritsugu became a freelancer like Natalia to hunt down heretical magi around the world. Natalia trained him not only in Magecraft, but in tracking, assassination, and all types of weaponry.

One of the mission they went was to hunt down the last Zepter head Heinrich Zepter. Heinrich Zepter was a magus who mastered in the revival of dead flesh. They've tracked Heinrich Zepter down in America, in a village called "Present Mountain" with two thousand people in the community. Kiritsugu and Natalia found out that that the whole community were part of Heinrich Zepter body and they destroyed him with a hand grenade by destroying his core.

During one mission on an Airbus A300 jumbo jet, they were following a magus known as the “Demonic Bee User”, Od Volsack. Natalia was in the plane during the flight while Kiritsugu waited at the destination. It was said that this magus successfully created Dead Apostles and could manipulate the Demonic Ghoul Bees under his control to use poisonous stings to increase the amount of Ghouls under his power. And those Bees caused a fatal disturbance in the plane after the death of Volsack. The Ghoul Bees raided towards the passengers one by one, and as every single passenger had become a Ghoul, were the situation deemed too risky and Kiritsugu shot the plane down before it could land, sacrificing Natalia in the process. In their last conversation via radio, he admitted that she was like a mother to him.

It was then that he became disillusioned with his ideal of becoming a 'hero of justice', as it was impossible to save one person without losing another. However, he continued to fight for this dream, to ensure that everything he had given up would not be in vain. He was eventually branded as the Magus Killer by the Association.

Before Fourth Grail War
Around eleven years before the fourth Holy Grail War, he took on a younger soldier as his apprentice, who he eventually named Maiya Hisau, training her in much the same way Natalia trained him. She became his assistant in the field and also his 'lover', in a purely sexual context.

Two years later, Kiritsugu was hired by the Einzbern family to be their representative in the coming conflict. He entrusted all his equipments including his Thompson Contender to Maiya before leaving. Believing that the Holy Grail could grant his wish for world peace, he left behind his work as a 'hero of justice'.

He first met Irisviel von Einzbern in a tank when Justacheit von Einzbern made her. The Drama CD expands on how they met and their intial reaction. Kiritsugu questioned Acht as Kiritsugu viewed Irisviel useless with no survival skills or defense skills.

Acht took this personally and threw away Irisviel in the disposal yard during in the blizzard to test her durability. Kiritsugu disgusted, rushed to save Irisviel and took her back to the old von Einzbern castle. When she recovered, Kiritsugu decided to educate Irisviel about the current world with movies, pictures and music. Gradually Irisviel became more eloquent and expressive, and she became interested in Kiritsugu himself. Despite Kiritsugu's initial hesitation, they eventually fell in love. However, Kiritsugu knew that a love between the two would be fruitless, as he was aware that he would sacrifice her for the Holy Grail. For Kiritsugu's sake, Irisviel wanted to conceive a child so he would have hope after the Fourth Grail War. Using his sperm, Irisviel artificially conceived a child, named Ilyasviel, who was born one year later.

Personality
Kiritsugu wishes to be a "hero of justice" that protects the weak. Kiritsugu's goal was initially to make his actions on the day of killing his father by his own hands meaningful and worthy. Only by hunting and assassinating all heretic magi like his father could he truly prevent such tragedies from occurring again. He lost all traces of youthful innocence after having spent his life going through countless battles while trying to obtain a utopia that could never be fulfilled. After finding out about the existence of the Grail, he wishes to use it to obtain that utopia. He feels no emotion from personal victories over his targets, seeing them as nothing more than successful taunts with calculated conclusions.

He attempts to kill off most of his emotions, acting as the "machine that is Emiya Kiritsugu", in pursuit of his goal. He has managed to become completely devoted to any duty without showing any emotional wavering, though he is prone to fall into moments of extreme emotion and despair occasionally. He admits that he is afraid and terrified of Kirei Kotomine, partly because of Kirei's bizarre personality and also because of the fact that he fears that Kirei might be the one and only person who can kill him. When examining the Contender, he begins to wonder if he will remember the touch of his wife and daughter after the Grail War ends, and falls into self-derision upon realizing the eight year old Ilya weighs less than a rifle. He dislikes such emotions interfering with his work, believing that his interactions with his family have made him more susceptible to sentimentalism in viewing the figures of his own wife and daughter in a passing mother holding her crying child.

He tries to hold to the belief that there is no differentiation in sacrifice, that all life is equal and choosing the path leading to a smaller sacrifice is for the best. With a target that must be eliminated in order to save the world by obtaining the Grail, killing one thousand people to save at least five billion more should be easy for him. He finds himself unable to do so when planning to destroy the Hyatt hotel. He hates the idea of fatal romanticism like the hope that the innocent tenants will be able to escape the hotel in time impeding his abilities. Such ideas and sentiment would kill him on the battlefield, so he feels that he must rid him self of them as much as possible.

He has a close connection to Maiya that is older than than the one with Irisviel, sharing a blood-stained existence not even his wife has ever seen. She acts to help balance his emotions, as she is often even more emotionless than him. Despite being close and having had a sexual relationship for a long duration of time, he shares no romantic feelings for her and attempts to simply regard her as a tool that will eventually die to serve her purpose. Because allowing his wife to sacrifice herself to complete the Grail is a betrayal towards her love, no matter what others say, it is necessary that he does not hesitate in this betrayal. Kiritsugu sees his sexual relationship with Maiya as a rehearsal before this betrayal, a form of self-abuse to steel his nerves while walking down this path. It is probably the sorriest excuse to have an affair, and it is essentially a negative spiral downward without an end.

During the last moments of Maiya's life, he attempts to calmly tell her that she has nothing to worry about because her tasks are complete, and simply state "you will die here." He finds himself unable to speak, and instead he almost finds himself crying for her. She eventually reminds him of his purpose and tells him to save his tears for Irisviel, allowing him to say "Maiya, your task is complete."

He stopped smoking while with the Einsbern family, but takes it up again during the Grail War. Partly because he couldn’t find his favorite brand, but mostly out of consideration for his wife and child. He instantly buys a pack out of habit and once again begins smoking as if hadn’t been ten years. Being a Japanese native, he feels better while in the country despite being used to travel.

Fate/Zero
Despite being the true Master of the Einzbern, Kiritsugu operated mostly in the background during the conflict, ambushing other Masters when they were otherwise occupied, while Saber, who was summoned using Excalibur's lost sheath as a catalyst, was partnered with Irisviel and made to act out in the open. This was to avoid conflict between Kiritsugu and Saber, as the methodologies of the two conflicted with each other too much. Saber and Irisviel traveled from Einzbern's castle in northern Europe to Japan by plane, while Kiritsugu took a different route, entering Fuyuki by ship and meeting with Maiya.

In the climax of the war, Kiritsugu fought the last Master, Kirei Kotomine to a standstill, both being consumed by the black 'mud' flowing out from the Holy Grail. There, Kiritsugu met 'Irisviel' again, now completely merged with the Grail. In his mind,

he was forced to confront the fact that his methods will eventually lead to him becoming the ultimate enemy of humanity, equal to Angra Mainyu itself - and, 'Irisviel' proclaimed, this path is correct. Kiritsugu, now realizing that the Grail is corrupted, rejected 'Irisiviel', who placed a curse on him - to never be free of regret until his painful death. Kirei, having went through the same experience, asked Kiritsugu why he rejected the Grail; Kiritsugu killed him after a vague response.

Kiritsugu appeared during the final battle between Archer and Saber and used all his remaining command seals to force Saber to destroy the Grail with Excalibur, causing her to fade away. However, Kiritsugu realized immediately after that this was a mistake - without a vessel to contain it, the 'mud' spilled from its core onto the streets below, causing a fire that eventually destroyed a large part of Shinto.

With the war's end, Kiritsugu discarded his merciless facade and sought to atone for his gruesome deeds. When he stumbled upon a dying Shirou, seemingly the only survivor after the fire, he was overjoyed at the opportunity to save a life. In order to revive him, Kiritsugu implanted Avalon into Shirou's body. Kiritsugu later adopted him as a son, settling in the new Emiya residence that he bought during the war.

He met Taiga Fujimura sometime after, and due to her resemblence to his first love, Shirley, he doted on her a great deal.

Once Shirou was old enough, Kiritsugu left Fuyuki several times, traveling back to the old von Einzbern castle, trying to save his daughter. However, he never managed to find his way past the bounded fields, having lost most of his magecraft abilities. After his betrayal, rather than seeking to punish him, Justacheit von Einzbern never again allows Kiritsugu into their Bounded Field and keeps him away from his daughter. Kiritsugu believes that he either wishes to exile him to carry the the shameful title of traitor for the rest of his life, or to impose the most severe punishment that can be inflicted by never allowing him to see his daughter again.

To ensure the destruction of the Great Grail, Kiritsugu used explosives to create a 'bump' in the nearby leyline, which would ensure a earthquake in thirty to forty years' time. By doing so he hoped to prevent a fifth war, but did not realize that the incomplete ending of the fourth war would cause the next war to occur in just ten years.

Angra Mainyu's curse eventually cost his life, as his limbs were lame, his sight failed, and most of his circuits became useless. His last moments were with Shirou, watching the moon outside his garden. It would be his happiest memory, during which he reminisced on his life, noting that it was full of regrets especially his inability to save his daughter. Revealing his childhood dream to Shirou about becoming an 'hero of Justice', Kiritsugu admitted that the dream was impossible to accomplish as he became an adult. Shirou, who looked up to Kiritsugu, hated the way he spoke of his weakness and reassured Kiritsugu that he can accomplish it as he is still a child in Kiritsugu's place.

Though Kiritsugu felt it was a fruitless dream, he did not tell Shirou what truly thought after seeing how enthusiastic Shirou was about it. He dies peacefully as he vaguely stared at the moon and commented how beautiful it is. He died at the age of thirty-four, five years after the end of the War, passing onto Shirou his ideal of a 'hero of justice'. In his last thoughts, he recalled when Shirley asked what kind of adult he wants to become and he had said: "I’ll never forget what I felt today. I want to be a hero of justice!"

Fate/Stay Night
Although he died before Fate/Stay Night, he is referenced by many characters. He is buried in the graveyard behind Ryuudouji, though Shirou rarely visits. His death left Shirou frustrated, depressed, and alone.

Shirou frequently recalls how Kiritsugu saved him and how Kiritsugu had offered to adopt him, along with revealing that he was a magus. When Shirou expressed interest in learning Magecraft, Kiritsugu disapproved and initially refused until Shirou's persistence wore him down. Advising that Magecraft should only be used in secret and to the benefit of others, without attracting suspicion or confusion, he taught Shirou very basic and incomplete knowledge of sorcery. However, this knowledge would lead Shirou down a dangerous path with little results.

Before dying, Kiritsugu had revealed to Shirou how he once strove to become a "Hero of Justice" - a person who could save everyone - but gave up once he realized it was impossible, citing it was a dream that could not be achieved by an adult. However, Shirou took the ideal as his own, promising to accomplish it in Kiritsugu's stead. Archer generally disapproves of the ideal; in Unlimited Blade Works, it revealed that Archer is a possible future incarnation of Shirou who he regretted the path he took. Archer's memories are incomplete, but he remembers certain events, one of the important events he remembered was when Kiritsugu saved his life after the fire. He understood Kiritsugu last words and experienced the same suffering that Kiritsugu had. In his duel against Shirou, he claims that his ideals are borrowed and he simply admired Kiritsugu when he saved him.

During the Fifth Holy Grail War, Saber revealed to Shirou that Kiritsugu was her Master in the Fourth Grail War. Furthermore, she is stunned into disbelief when she sees how Kiritsugu was an entirely different person in Shirou's memories. In the Fate scenario, she wants to know why Kiritsugu betrayed her until Kirei Kotomine reveals that the Grail was tainted. Finally understanding why Kiritsugu destroyed the Grail, she eventually accepts and agrees with her former Master's actions. Saber also expresses gratitude toward Kiritsugu for implanted Avalon in Shirou which saved his life many times, first when Berserker attacked Shirou and when Kotomine heavily injured him.

Upon her entry into the war, Illyaviel von Einzbern specifically targets Shirou because of his connection to Kiritsugu. Believing that Shirou had stolen her father away and that Kiritsugu had left her mother to die in the Fourth Grail War, she attempts to fulfill the Einzbern's desire to achieve the Third Magic and avenge their loss after Kiritsugu's betrayal. In the Heaven's Feel scenario, after being abducted by Dark Sakura and informed about Avenger and the corruption of the Holy Grail, she admits that her father was correct in his choice to destroy the Grail.

When Kotomine first meets Shirou, his interest is piqued because Shirou shares the same surname as Kiritsugu. In the Fate and Heaven's Feel routes, he revealed everything about his deeds during the Fourth Grail War. In the former scenario, Kotomine used the power of Angra Mainyu to curse Shirou just like Kiritsugu.

Fate/hollow ataraxia
Kiritsugu makes no appearances in Fate/hollow ataraxia, though it is common knowledge that Illyaviel is Kiritsugu's daughter. Taiga often asks Shirou to take her to visit Kiritsugu's grave.

Abilities
Kiritsugu is only average as a magus, and instead specializes as a "Magus Killer." He has a number of specialties that would not make him very notable within the Mage's Association, but instead make him useful for higher-ups when they need an assassin to kill other heretical magi. Compared to someone like Rin Tohsaka, who would have a high numerical value as a magus, Kiritsugu would have a low value as a magus, but a much higher evaluation as a specialist. His relationship with the Association is much like how the Church treats its Executors. His abilities are great enough that even the Church considers him to be "an individual that requires surveillance." He is noted for many cases of missing persons and accidents believed to be magi he has killed, and many tragedies of the past reported as major acts of terrorism are in reality criminal acts committed for the sake of killing one magus. While there is no actual evidence, events such as planting a bomb in public and striking down an airplane with many passengers on board are believed to be caused by him.

After becoming cursed by Angra Mainyu, he is slowly killed over a number of years as his flesh keeps growing weaker, his limbs become atrophied, and he completely loses the ability to use magecraft. He becomes unable to even find the starting point of a Bounded Field the “Magus Killer” would be able to forcibly break through, and he is left to wander in a blizzard without any hope of finding it. Once he fully succumbs to the curse, he dies peacefully.

Combat tactics
Kiritsugu is a very unconventional magus, known as a Spellcaster, that treats magecraft as a mere tool in which he has acquired knowledge rather than the object of his lifelong goals, and he freely supplements it with the use of modern technology to gain an advantage over enemies. Compared to someone like Tokiomi Tohsaka, who refuses to use phones and the like despite their convenience, he freely uses anything at his disposal in order to accomplish his goals. He learned most of his skills from studying Natalia's abilities while also refining his own as her assistant in his pursuit to become a "hunter" that stops other heretical magi like his father. Much of his ability comes from the fact that he can act cold and ruthless to complete his objectives. After having spent time in retirement with his wife and daughter, he believes he has degraded a great deal compared to the Emiya Kiritsugu from nine years before. He is no longer as willing or capable of being as ruthless as he once was due to his interactions with them, which he believes he needs to change. He wishes to restore his cold manner of judgement as fast as possible in order to be able to obtain the Grail.

He developed his skills working as a Sealing Designation Enforcer for a number of years, learning methods of tracking, assassination, the usage of various weapons, and other skills needed to be able to catch up to his prey under all situations and conditions and bring it down. He sought to have his body master the skill of "killing people" that humans have spent an endless amount of time and intelligence to research. He is very skilled with using numerous blasting techniques from the past to the present, and he feels a certain appreciation for the certain art of destruction. He uses C4 combined with a precision blasting demolition technique used primarily to demolish tall buildings, allowing him to destroy the Hyatt hotel with a minimum amount of explosives. With the blueprints and planning, it only takes him an hour execute the entire plan. Targeting the load-bearing walls and key support structures, it collapses downward and inward on its own weight without any debris spreading onto the surrounding streets.

He is very familiar with the workings of Magic Circuits and the related temperature changes in the body of the practitioner. Having trained and studied the correlation, he is able to read the current status of the Magic Circuits through the heat distribution of the practitioner when viewed on the thermal output of a heat detecting scope. He is able to tell the difference between an ordinary person and a magus, allowing him to seize an opportunity to shoot upon the release of prana. Compared to magecraft, which can see through the dark better and detect the position of an enemy magus, it can be said guns fall behind. Its advantage is that it takes no prana to use firearms, leaving a magus unsuited to the battle conditions of a soldier trapped in the dark and unable to detect any prana.

He is extremely skilled in penetrating Bounded Fields, allowing him to break through the Tohsaka residence's strong bounded field in three hours. It is an almost miraculous method allowing him to overcome a first-rate security system specifically guarding against magi that wouldn't be broken even if attacked continuously for a whole year by magecraft. Due to it being created with magi in mind, he was able to overcome it precisely because he is someone who does not seek results by way of magecraft and from his experience in fighting against magi by perceiving traps wrought through magecraft. He supplements familiars with miniature CCD camera tied on the abdomen as a measure of recording the true nature of the area. There are often illusions and camouflaged bounded fields based on using suggestions on an observer, but most magi would never develop countermeasures for electronic-based threats. Even though it slows the the familiar's speed, it is also useful to have video records to rewatch events at a later time or show them to others.

Anti-magi tactics
He has the mindset of skilled assassin, and rather than facing another magus in a direct duel of abilities, such as in a battle between their Mystic Codes, he makes use of various plans, traps, and schemes that utilize both magecraft and modern weaponry in order to take out his targets. He preys on the weak point of magi, their negligence from arrogance, which makes them believe that the only threat to them cannot be anything other than a similar magus. He relies on the fact that a self-conscious magus, having stepped into a world of mysteries beyond human intellect, is unable to relate to the stereotypes of a narrower world, such as the conditions of a battlefield or scenarios a regular soldier may face. He follows the methodology that the attack the enemy doesn't expect is a shortcut for all battles, and preys on the fact that they constantly stay on alert to the slightest trace of magecraft.

Magi generally only hone their skills and counter measures towards thaumaturgical threats, ignoring any attack that is purely physical and void of magecraft. They view the sharpest knives and strongest bullets as secondary menaces they have no need to fear. Before such an attack actually pierces their flesh, they are confident in their illusions, paralysis methods, and defensive bounded fields being able to completely negate any such attacks. They despise technology and underestimate what a human without magecraft can accomplish, which makes them weak to non-magical attacks from Kiritsugu's experience. Though most magi would take the idea of entering the lair of another magus as a challenge worth taking, Kiritsugu takes an opposite approach. When faced with the Hyatt hotel, Kayneth's stronghold, which has been fortified with magical furnaces, spirits and apparitions, and a large Bounded Field, Kiritsugu decides to destroy the entire building. With as much pride Kayneth has as a magus, he is willing to stay inside, believing with all certainty that Kiritsugu will invade rather than giving any thought that his entire castle will be destroyed instead.

While Kiritsugu is able to fight most magi with modern weaponry, there are some special cases he calls "formidable enemies." Following the methodology that technology is a blind spot to most magi, he finds that most them can be defeated by night vision and a heat sensor scope. Though most magi won't deviate from that generality, there exist those that cannot be measured with rules and experience. Against those who Kiritsugu's normal strategies will not prevail against, he must act as a magus and use his Mystic Code, which is his most powerful weapon. Even facing such an opponent, he is extremely adept at forming strategies and analyzing enemy movements and magecraft. Within just one encounter with Kayneth's Mystic Code, he is able to find three weaknesses, form a countermeasure against it, and plan for his final assault.

Partners
Kiritsugu is able to work in tandem with multiple parties, but he regards those people simply as "tools" to further his goals. His relationship with Hisau Maiya is that of a pupil and a teacher, but due to viewing magecraft as a tool, there isn’t a single sense of master and pupil between them. He has only taught her a “way to fight” so that he may also freely use her as a “tool.” She acts as a vanguard scout, and due to years of working together, they are very in sync with each other's actions. She is a "supporting machine" whose actions are even more akin to a machine than those of the machine called Emiya Kiritsugu, and an " indispensable final weapon" to help him win the battle. Out of all of his teachings, she is most skilled with using bat familiars supplemented with cameras, and she makes use of a Steyr AUG assault rifle with a replaced night vision scope while still remaining under five kilograms. She is more of a solider than a direct combatant, so he generally trusts her with reconnaissance and scouting due to her skills with familiars, and he allows her to procure all of his equipment. They have exchanged strands of hair between them, which Kiritsugu used as the basis for a spell in order to act as a measure indicating the worst-case scenario in which it has become impossible to use a wireless network or familiar to convey information. The enchanted strands were embedded in the subcutaneous tissue of their pinky fingers with the purpose of sensing if the Magic Circuits of one of them entered a state of extreme stagnation, the stage at which one's life force was weak on the verge of impasse with death. If the hair embedded in either one of their fingers starts to burn, it is a warning to notify them of the existence of danger, and it really essentially acts only as a signal to inform that "it is already too late."

He follows the methodology that Servants are the tools of their Masters, and that no matter how famous the hero, they will be nothing more than that as long as they are summoned as a Servant. Despite Saber being one of the most powerful Servants of the Saber class, he finds that Assassin or Caster would suit his style of combat more appropriately. Due to Saber's chivalrous preference for direct confrontations and fair battles, it is hard for him to coordinate with her. He instead has Irisviel pretend to act as Saber's Master, while he acts from the shadows. They only speak a few times in total, and are unable to ever agree with each others methodology.

Equipment
Kiritsugu lacks the various ritualistic catalysts used by normal magi like a dagger, cup, talisman, elixir, or spiritual container. He instead uses all state of the art weaponry that are unable to store any prana, which is the "heresy" that earned him his title. He utilizes a large number of different firearms and weapons to kill his targets. He also makes use of personal hand grenades, stun grenades, smoke grenades, C2 plastic explosives, and landmines, and he is skilled in incorporating them into traps with trip wires, hidden fuses, and a detonation system using a cellphone to trigger them through modified communication loops. He has number of Claymores, which simultaneously release around seven hundred steel balls with diameters of only one or two millimeters. They radiate outward in all directions in a fan formation with enough power to destroy an infantry unit in one strike. He is also familiar with setting up surveillance systems, allowing him to use a number of concealed CCD cameras throughout the Einzbern castle. He also has specialized magical equipment, such as an eye drop bottle filled with a liquid made from refining the body fluids of a succubus. It is sensitive to the blood of men and aged things, allowing it to immediately identify such substances. It is capable of comparing substances and distinguish differences accurately, allowing him to compare left over residue from shaving to a bloodstain to identify both as being left by Tokiomi.

Avalon
Avalon, Saber's Noble Phantasm, is placed in his possession by Acht in order to be used a summoning catalyst. Rather than allowing Saber to have it, he hides its existence from her and keeps it for his own use. Normally, it would be used as the trump card of Kiritsugu as Saber's Master, but he isn't present on the direct battlefield. It is a useless tool to him due to that Saber would not be able to provide it with prana since he is working so far apart from her. He leaves it for Irisviel's protection due to her acting as the front line substitute Master for most of the Grail War. Once returned to him, he seals it inside himself as a Conceptual Weapon and makes use of the contract with Saber to provide the full effects of its immortality. It revives him after his heart and lungs are completely destroyed by completely healing him seconds before his blood-deprived brain is about to die due to lack of oxygen. Even he is surprised with its potency, and decides to work it into his battle strategy to counter the negative effects of Innate Time Control. While it can heal both injures caused by enemies and damage dealt to himself, it only nullifies the damage without taking away his pain. Calico M950Edit

The Calico M950 is a submachine gun used by Kiritsugu and Maiya as a reserve side arm. It has a compact size similar to a large handgun with a reinforced plastic that makes it look more like a toy when compared to the Walther. It has a unique helical magazine that allows for fifty Parabellum rounds fired at a rate of seven hundred shots per minute. It is also equipped with a sound suppressor, laser sight, and foregrip.

Thompson Contender
The Thompson Contender, also called the Thompson/Center Arms Contender Custom, is a special piece of equipment compared to his other weapons, which are armaments for the Magus Killer that can simply be bought and replaced at any time. It is something that cannot be bought with money that represents Kiritsugu as a magus, a Mystic Code with which he can use magecraft during battle against another magus. It is a one of a kind weapon only for his use that he has favored on many battlefields. It is used in conjunction with Origin Bullets, which are special Conceptual Weapons that utilize his Kiritsugu's Origin to its fullest extent by actualizing it within a target. The bullets were created from his first and second ribs on both sides being cut off, extracted from his body, ground into dust, condensed with a craft to preserve his soul, and sealed within sixty-six bullets as their core. The gun and bullets are stored within a rosewood case, which was left with in the care of Maiya during his nine years of retirement. It is 444mm and 1700g, with his modifications bringing the total weight to 2060g.

The Contender was developed in 1967 by American company Thompson/Center Arms. It is a break-open single-shot pistol meant for sport shooting. Simple yet powerful, the weapon can, with little modification, be used to shoot various ammunition ranging from .22 LR to rifle bullets. While it is not suited for real combat, it was chosen as his Mystic Code due to it being able to deal the maximum physical damage possible. Its grip and forearm are carved in walnut, making it reminiscent of a dagger in its scabbard. The only visible mechanical parts are the trigger and the hammer, with neither a cylinder nor a slide on the simple exterior, making it similar to the percussion pistols used in the last hours of the Middle Ages. The lack of complex parts between the barrel and trigger allows for high accuracy. Kiritsugu's is customized with a fourteen inch rifled barrel made for hunting specifications and fitted for .30-06 Springfield bullets. The cartridge of the bullet has a bottleneck structure, and its size and power level on an entirely different level from a handgun bullet. The .30-06 is 10% stronger than the .308 Winchester rifle bullet, and even surpasses the hand cannon class of a Magnum bullet.

While it is a powerful weapon with especially powerful bullets displaying destructive power capable of easily puncturing bulletproof vests and killing large animals in a single shot when discharged from a handgun, its true use lies in the specialized firing pin and additional magical modifications for firing the Origin Bullets. Origin Bullets, containing part of Kiritsugu's soul, actualize his Origin of "Severing and Binding" upon contact with the target, which can cripple living creatures that are fired upon. There are no wounds or bleeding, but the area or body part where the target is hit appears to be suffering from necrosis. While it seems to have healed properly on the surface, the nerves and capillaries will never regenerate properly and the original function will be forever lost. While it would be bad for a living being to be hit by it, as a Conceptual Weapon, this bullet poses an even graver threat to magi in particular. Out of the sixty-six Bullets, thirty-seven bullets have been used, and not a single one was wasted after completely destroying thirty-seven magi. During the Grail War, he has access to twelve bullets, and Keyneth becomes the victim of the thirty-eighth bullet. The only person to render it ineffective is Kotomine due to the fact that he doesn't fight like an orthodox magus.

Origin Bullets will immediately affect magi upon coming in contact with their magecraft. The only practical way for magi to defend against one is to discard all magecraft and defend purely by physical means, but he uses a particularly malicious method forcing the use of magecraft by making it impossible to physically block it. The bullets excel in penetration, and there is little outside of magecraft capable of blocking the specialized hunting rifle unless they are protected by the military-grade armor of an armored vehicle. Being forced to defend with magecraft, the impact of the Origin within the bullet affects everything all the way down to the Magic Circuits of the practitioner. If a magus' Circuits are a high-voltage power cable, then the impact of the bullet is comparatively a drop of water attaching itself to a thickly-placed electrical circuit. Once a conductive liquid becomes attached, the short-circuiting current will destroy the circuit itself, resulting in permanent damage. The more intense the pressure used to gather densely-packed prana for defense, the more active Magic Circuits will be functioning upon the moment of contact, and the more severe the destructive power of the bullet becomes. The "Severing" aspect will cause prana stored within the Circuits to ignore the paths within the body, flowing chaotically and destroying it in the process. Afterward, the circuits will be bound together again with the "Binding" aspect, rendering them permanently inoperable and destroying the target's magecraft abilities. If used against a magus not actively using their Magic Circuits, such as Kotomine supplementing his own abilities with Command Spells instead of his own undeveloped Magic Circuits, it will target the source of the abilities instead. Targeting the one-use seal, it simply dissipates after being struck by the bullet without affecting Kotomine.

Kiritsugu initially uses normal .30-06 Springfield bullets in order provoke the enemy into believing that those are his strongest weapons. Utilizing the bullets that have an initial velocity 2.5 times higher than 9mm bullets used by his Calico and seven times the destructive power, they become focused upon making sure that they can consciously defend against such an attack and focus most of their prana towards that task. When someone is provoked into using their utmost amount of prana, the damage is completely fatal. It causes excruciating pain within the body as the nervous system spasms while being broken down. Their internal organs are almost destroyed, and numerous muscles and nerves are damaged. If they do not die instantly, the wounds will quickly prove fatal, and even if healed by a magus, it would be impossible to recover enough to even stand again. Once Keyneth is struck, it takes a great deal of money and an expert puppet master to simply get his hands working enough to move a wheelchair.

Walther WA2000
The Walther WA2000 is a super heavyweight, semi-automatic sniper rifle of the highest class and performance that is the pinnacle of the latest electronic techniques. It costs $12,000 due to only being one of the 154 units produced. It is a rifle with a compact size measuring a little over ninety centimeters in length with the bullpup structure of the gunbarrel with a gas-operated magazine measuring at a length of 65 centimeters. It uses a .300 Winchester Magnum shell that has an effective range of one thousand meters. It doesn’t have the standard Smith & Bender sighting device, but rather he installed a pair of extra-large optic devices as a special scope mount fixed in parallel above the barrel and on the left flank.

The unit on the main side is the AN/PVS04, the latest night vision scope used by the US armed forces that has been banned from being exported to prevent the leaking of technology to other countries. It uses a super sensitive video camera that acts as a light electrical amplifier with a lens, raising and displaying a perfect brightness. Acting as an electronic "owl eye", it multiplies the range of vision by 3.6, allowing it to view up to six hundred yards under the moonlight or four hundred yards in starlight. The second unit is a specter IR heat detector scope installed as sideways support. It is also electronically equipped for night vision, but displays the subject's heat pattern on the image display rather than acting as an intensity amplifier. It can perceive temperature variations from -5 to 60°C up to two hundred meters with an 1.8 magnification.

The scopes are large and bulky, being the size of a plastic bottle and giving the compact gun an air of unbalance, which brings the total weight of the gun to over ten kilos. Even with the steady progress of miniaturization, they are still large even compared to standard optic devices. It is a weapon more suited to a support fire squad more than a sniping weapon, and its practical use is hindered. Despite the challenge, it was within his calculations in best managing to make use of the weapon. The joint use of both scopes allows him not only the ability to fight in darkness, but they have also been configured to allow him to face off against a magus. Sensing the Magic Circuits within the dark, it can fire upon them from hundreds of meters away without them being able to detect him at all.

Magecraft
The Emiya Thaumaturgical Crest is carved on Kiritsugu's back, but he was unable to inherit it properly from his father as a normal magus. Due to the Sealing Designation, Noritaka's body was retained by the Association, and all the important parts of the Crest were confiscated. Through Natalia's negotiations, Kiritsugu was allowed to inherit part of the Crest, but it was only a "fragment" that contained less than half of the original amount. It was enough that he was able to use his abilities as a magus, but he had little interest in continuing the research in the first place. His only interest was whether it would prove practical as a tool in combat situations. While he relies on modern technology, he is still capable of using various different spells and techniques in his work. He is capable of using night sight by focusing prana to his eyes, allowing him to instantly see with impeccable clarity in the dark. He is proficient in using familiars, and he has taught Maiya how to use them as well. He can use basic hypnotic suggestions on those with no natural resistance to magecraft by making the target focus on his eyes.

Kiritsugu's Elemental Affinity is the dual attributes of Fire and Earth, and as composite attributes, they are linked to his dual Origins, Severing and Binding. The previous generation of the Emiya family was at a loss upon finding the nature of his Origin, and named him Kiritsugu due to the strange results. Severing and Binding is different from the idea of "destruction and rebirth." There is no chance of "recovery" in the case of binding, such as a string being cut and connected back together by tying the two pieces. While it is once again whole, there is forever an irreversible "corruption" in the form of a change in thickness where the knot it tied. It takes form in his everyday life when doing hands-on work, which caused him to become particularly aware of his Origin. While he can fix normal contraptions, he is not very skilled in working with delicate machinery. His unskilled hands suddenly cause everything to become the opposite, and the more he wants to fix something, the worse the damage becomes for the machine. He can use handcraft to piece together a snapped metal wire while still restoring the original function, but fixing a delicate electric circuit using the same principles will have fatal results. It is not something that will work as long as everything is connected, and if the connections are out of order, the circuit will lose its function. Rather than being caused by his personality or temperament, it is the true essence of the root deep within his soul.

Innate Time Control
Innate Time Control is Kiritsugu's personal application of the Emiya family's magecraft. They spent generations researching and seeking the magecraft that controls time, eventually reaching "Time Manipulation", which is the ability to separate the passage of time inside a designated space from the "flow of time" in the outside world. It is classified as High-Thaumaturgy in the form of a Bounded Field that can be regarded as a type of Reality Marble in a way, but still not something extraordinarily difficult to utilize like other time related magecraft or something on the level of the True Magic that is unable to be replicated. It allows for "time adjustment" that can only stagnate the time which has passed and accelerate time in the future rather than something more advanced like "time modification", which has the ability to reverse cause and effect and change the past. The major problem is that the practitioner needs to consider the size of the Bounded Field and the scope of time that needs to be modified. It requires a large amount of prana and similar rituals in the same magnitude of High-Thaumaturgy to activate it. It would normally be applied to a wide area and a long period of time, taking longer to set up and more prana to utilize it as the Bounded Field becomes larger and the deviation in time becomes longer.

It is not an ability that can be used on the battlefield where strategies must be quickly made in order to survive, as it must be prepared beforehand and used strategically even after the preparations. The Magic Crest of the Emiya family contains generations of inherited research, but that is unimportant to Kiritsugu. It was a useless inheritance until he found a way to use it to its maximum potential in a combat situation. He worked around the issue of size and prana consumption by creating a flexible method of utilizing it on a small scale that only applies to himself. This allows for the establishment of the Reality Marble at any given time without the need of extended rituals. It is impossible to completely isolate the flesh from the outside world, but the ability can minimize the effect the outside world has on the body. Keeping the scope of the spell to a minimal bounded field within his own body, it doesn't allow for the world to be affected, but rather allows for Kiritsugu to "adjust" a few seconds of time within his own body. He uses the chant Time alter, followed by the degree of speed he wishes to use. The chant accel allows him to speed up, while stagnate slows him down. He can use Release alter to stop it an any point.

Time alter - double accel is his most used version, allowing him to move faster than the human eye can see. It speeds up his blood flow, hemoglobin metabolism, and muscle movement all at the same time. Using this brief burst of speed, he can use his own physical skills and reaction speed at a level far above human limitations. It allows for split second evasion in front of an enemy, and its power of mobility can make for one of his greatest defenses. Normally double accel is enough to push his body past its limits with brief use, but with Avalon providing regeneration, he is capable of using Time alter - triple accel and the quadruple-accelerated time of Time alter - square accel for an extended period of time. Using stagnate, he can slow his biological processes, and using Time alter - triple stagnate reduces them to one third of their normal speed, slowing his heart beat to the point where he can barely feel it himself, slowing his breathing so it lags, and reducing his metabolism to the point where body temperature cools quickly enough to almost match room temperature. The sound of his presence is reduced enough that Volumen Hydragyrum is unable to make out his breathing and heart beat from the other noises in the natural world, and it is unable to recognize him by using the standards of a human. While there aren't any changes within the actual world, his optic nerves and ear drums register what he sees and hears from within the bounded field. His cornea receive three times the light a person's eyes normally receive, which makes his field of view extremely bright, and his hearing is dulled.

Even with his minimalistic approach, it is still High-Thaumaturgy far above the level of basic physical enchantment that causes inconsistencies between the flow of time inside and outside the field. Once the movement is complete and the field is removed, natural forces, the "world’s own adjustment", will forcefully adjust the "incorrect time." This places a large burden on Kiritsugu with each use, as the bounded field where the "errors have occurred" is within his own physical body. In order to get back in sync with the normal time flow, adjustments occurring within his flesh greatly damage him. Even brief use has him accompanying death, and continuous activation is nothing less than suicide, making it his riskiest technique. When returning to normal from stagnating, he suffer from the blood flow speeding up back to original speed, which causes burst capillaries and internal bleeding. Without the use of Avalon, double accel is his limit when speeding up, and even a few seconds of it is enough to rupture numerous blood vessels and cause fractures in the bones of his limbs due to the burden. Provided with constant regeneration from Avalon, he makes use of the ability's purpose as a strategic weapon to its full potential by utilizing higher levels while enduring his body breaking down and healing at an extremely high rate. He still feels the torn tendons and snapping bones tormenting his nerves while shedding mists of blood with every movement, but the regeneration allows him to keep fighting with accelerated speed for a much longer duration of time.
