A Mystic Code: Magic Formal Wear (魔術礼装, Majutsu Reisō?), or simply Formal Wear (礼装, Reisō?), is a tool that magi use to support their execution of Magecraft. Top tier Mystic Codes are said to have the equivalent power to a missile. Others have pseudo-personalities, essentially acting like loyal robots that carried out their users’ orders, but many are capable of more adaptive autonomous thought than modern AI.
There are many different types of functions and shapes to Mystic Codes, but these are generally broken up into two types. The first are those that supplement the magic energy of a magus when he uses magic. The second are those where the Mystic Code itself has a predetermined set effect and a function that activates that effect when used.
- Auxiliary Mystic Code (補助礼装, Hojo Reisō?)
- An Auxiliary-type one can be used for magical energy amplification or storage, prepared to strengthen a spell. They are orthodox Mystic Codes for support. Some jewels and Azoth Swords are of this type.
- Specialised Mystic Code (限定礼装, Gentei Reisō?)
- A Specialised-type one performs Magecrafts contained within it automatically when supplied magical energy by its user. While their usage is limited, they can be tremendously efficient in what they do. Many of the Noble Phantasms, some jewels, the Jeweled Sword Zelretch and the Dress of Heaven are of this type. A regular Mystic Code would not be much of a weapon against Dark Sakura, but the Jewel Sword is kind of a foul play as it can start up the Second Magic.
- Supreme Mystic Code (至上礼装, Shijō Reisō?)
- A Mystic Code given this title is worthy of symbolizing any one of families to which the Twelve Lords of the Clock Tower and people in the next highest posts belong. The El-Melloi family's Supreme Mystic Code is Volumen Hydrargyrum.
Amongst Mystic Codes there are several which are unique enough even amongst Magi to warrant interest. Examples of which are as follows.
- Kiritsugu Emiya's Mystic Code, the Thompson Contender, is unique by virtue of being a pistol, a tool normally despised by Magus. Combining bullets made from his own rib bones and the high stopping power of the weapon itself, it is this one of a kind tool that made him a terrifying Magus Killer.
- Tohsaka Jewel Magic, whilst the jewels themselves can count as Mystic Codes, users of this type of Magecraft can make more specialised tools to act as their personal Mystic Code. Tokiomi Tohsaka created a staff topped with a jewel that allowed him to cast powerful spells quickly and was not used up after a single use, unlike many of Rin's attacks. Similarly, he gifted Kirei Kotomine with a Azoth Sword that was designed in much the same manner.

Magical Formal Wear: Mystic Code
Magic formal wear are tools that magi use to support their execution of magics and are also called "Mystic Codes" or "Formal Wear". There are many different types of functions and shapes to Mystic Codes, but these are generally broken up into two types. The first are those that supplement the magic energy of a magus when he uses magic. The second are those where the Mystic Code itself has a predetermined set effect and a function that activates that effect when used.
Similar to Mystic Codes, there are also "Conceptual Arms". These are weapons where meaning is imparted to items via accumulated history, lore, rituals and the sort, and made so as to affect souls and spiritual bodies.
In Fate/stay night, the "Dress of Heaven" and "Jewel Sword Zelretch" are Mystic Codes, while the "Black Keys" are "Conceptual Arms".
•Support Formal Wear: Support Code
Mystic Codes that function as aids to the use of magic are called Support Codes. Specifically, many Mystic Codes function to amplify or enhance a magus’ power. By using a Support Code, one can power magic with less energy, or utilize great quantities of energy beyond one’s personal limits. For this reason, it is common for any magus to maintain at least one Mystic Code as an energy reserve.
For portability and ease of deployment, form factors that can easily be carried in the hand are favored. The items that magi favor include daggers, short canes, books, jewels, and so forth.
One of Tohsaka Rin’s Support Codes. It is a typical Mystic Code, given as a gift to commemorate one’s coming of age.
In contrast to the auxiliary function of Support Codes, the capability of Mystic Codes to actualize phenomena on their own is called a Limited Function. A complicated procedure is not required to use a Limited Function; instead, one can just flow energy into the Mystic Code.
Mystic Codes that have Limited Functions cannot be used by just any magus, unlike Support Codes. In addition to allowing one to achieve effects that cannot be achieved with one’s own magic, they are highly practical because they can easily be used without performing a complex ritual.
Although Noble Phantasms are paired with Heroic Spirits from legend, and so incomparably powerful as to be considered in a league of their own, most Noble Phantasms that Heroic Spirits possess are Mystic Codes with Limited Functions.
Dress of Heaven
A Mystic Code passed down through the Einzbern lineage. It is the final stage of the Holy Grail War, functioning to control the Greater Grail. Illya, who was designed as a Holy Grail, is in her completed form when she wears the dress.
Jewel Sword Zelretch
This Mystic Code, possessed by the Wizard Marshal Zelretch, has the Limited Function to use the Second Magic. It is among the apex of Mystic Codes, able to tap and use the mana sources of infinite parallel worlds.

 Fate/stay night - Weapon Menu: Azoth Sword [T]
An item of ceremonial magical equipment that Rin treasures.
This object is not a weapon as it amplifies the magical energy of the owner, and it is instead used as a staff to support and amplify magic usage.
It is a popular item in the Magic Association, and a common commemorative gift given by masters and parents when entering adulthood.
The original is said to be a dagger favored by the man who established the foundations of present day alchemy.
 Fate/side material - Encyclopedia: Tohsaka Rin [Person's name], p.067-068 [T]
Rin Tohsaka [Person's name]
Current head of the distinguished Tohsaka family, and one of the main heroines of Fate/stay night. As a Master, she spent just as much time quarreling with Shirou as she did cooperating with him.
Her manner of speech is often hostile and dismissive of other people, but deep down she has a caring, big-sisterly disposition.
Her tendency of making trivial mistakes at the worst possible moment is a hereditary curse.
Though she really is a lot nicer than she seems, in the end she always makes her decisions based on cold, rational logic. In her own words, it's "not a very cute personality".
There are even times when she thinks she might lack any sort of "girlishness" at all, and it's starting to become something of a complex for her.
In fact, her choice in personal clothes is probably an overreaction to that. Still, showing that much leg… a pure and wholesome boy won't know where to look. Please, try to bear with it, Shirou.
Her hobbies are admiring jewels and bullying Shirou.
She's a mischievous girl at heart, so she loves teasing serious people. Please, try to bear with it, Shirou.
As far as sorcery goes, she specializes in the flow and conversion of magical energy.
Since it's not a sorcery trait well-suited for combat, she stores away magical energy in jewels ahead of time, and uses them as disposable, limited-function mystic codes.
Aside from that, she also practices pseudo-karate as a form of self-defense.
Her instructor in martial arts is Kotomine. That fake priest was responsible for the sequence of moves she used to corner Caster.
By the way, she had the most screen time out of every character in Fate/stay night.
 Fate/stay night - Weapon Menu: Gem Sword Zelretch [T]
Gem Sword Zelretch
A limited magic item that possesses the abilities of the sorcery.
While it cannot open doors to parallel worlds, it allows a degree of intervention through looking between them, and it even allows for sharing of magical energy present in the air.
The gem part of the name comes from the kaleidoscopic appearance of its polyhedral structure.
There's no need to explain why Kaleidoscope is Zelretch's nickname.
 Lord El-Melloi II Case Files material - Encyclopedia: Volumen Hydrargyrum [Mystic Code], p.099
Moon Spirit’s Spinal Fluid [Mystic Code]
Supreme Mystic Code of the El-Melloi family.
The term Supreme Mystic Code refers to a Mystic Code sufficient to be called symbolic of a family of similar level to one of the Twelve Lords of the Clock Tower. In Volumen Hydrargyrum’s case, it was created by Lord Kayneth in his early twenties, a clear demonstration of the once-Lord’s exceptional talent.
Ever changing in form, it is a Mystic Code capable of performing both offensively and defensively without showing any openings. Its true nature however is that of a remote processor.
Upon inheriting it, Reines followed the advice of El-Melloi II and created a familiar out of it, endowing it with an elementary kind of artificial intelligence. It was the best advice for Reines who, rather than having the exceptional Magic Circuits of her predecessor, instead boasted a talent for precise control.
By forcing it to remember Reines’ precise control, the artificial intelligence is able to imitate it perfectly. The newly christened Trimmau being capable of taking so many various forms is primarily a result of this advice she received.
In addition, because of Trimmau’s nature, it has also learned a great many things from Flat’s magical hacking. Though that has included a large amount of unnecessary wit and famous sayings, Reines has thus far turned a blind eye to it for the sake of the other merits it brings.
 Lord El-Melloi II Case Files material - Encyclopedia: Add [Mystic Code/Other], p.097
Add [Mystic Code/Other]
The Mystic Code sealing the Noble Phantasm Rhongomyniad, possessed by Gray.
Created by the Witch Morgan, she based the artificial personality within it on the knight with the least adoration for King Arthur from the Round Table. Thinking about the Atlas Contract Incident, that trick seemed more like a plot to “prevent the return of King Arthur” at that time. It was like a strange trick to say “I’ll help with your revival, but I don’t want it to succeed.”
Before being created, its true form was that of the Logos React Replica. Using the extreme calculative ability inherited from the Seven Superweapons of the Atlas Institute, it continues to seal Rhongomyniad within it. In its released form, it can of course take the shape of a scythe, but also that of a hammer, shield, hook spear, or even a boomerang. It is also able to use its immense calculative ability to display a portion of the power of Rhongomyniad itself. The appearance of the knight in “The Atlas Contract” occurred due to the same theoretical principle. Their personality was a result of a complex merger of that original knight’s and the present day Add’s, so strictly speaking it belonged to neither of them. That was likely why it was able to finally deploy the Pseudo Phantasm.
For Gray, Add was her only friend for a long time.
The name Add comes both from the word “addition” and from the tail end of the word “Rhongomyniad.”

Originally, the effect of this Noble Phantasm was to amplify・supplement・strengthen his magecraft, but - by performing ritual magecraft by means of the magical power of the blade, and employing the five elements as catalyst - a temporary pseudo-composition of True Ether from the Age of Gods is also possible.
He then smashes the surroundings with the fearsome destructive power of this True Ether (fake).
The wish he once had for the Holy Grail was "to reach the Root".
Furthermore, he also wanted to ascertain the authenticity of his personal opinion regarding how the light of the star (like that of a holy sword) is indeed a light shining from the Root-- or so it was.
But it may be that he is currently seeking for atonement instead.

Barrel Replica [Weapon name]
The mystic code possessed by Sion. A replica of the Black Barrel, one of the seven superweapons on display at the Atlas Institute. It is a conceptual armament of "natural lifespan", which demonstrates a toxin (attack power) in proportion to the predestined span of the target's life.
Sion uses this Barrel Replica in her Arc Drive, but it seems that she isn't utilizing its original function.
Also, though she discharges the energy horizontally in her Last Arc, Barrel Replica Obelisk, she is able to avoid being blown back by the recoil by anchoring her body to the ground with Etherlite.
 Fate/Apocrypha material - Encyclopedia: Coupled Reinforcement Mystic Codes [Others], p.183 [T]
Coupled Reinforcement Mystic Codes [Others]
Bronze-Link Manipulators. A Mystic Code that Fiore designed herself. It takes over the role of her paralyzed legs. It consists of four prosthetic arms equipped to her back. It was forged using a special alloy that easily conducts prana and is possessed by four animal (dog) spirits, so while Fiore can move them according to her will, the arms also move automatically to protect their master.
Unlike the Volumen Hydrargyrum that Kayneth El-Melloi designed, its movement pattern memories are kept to a minimum. When too many movement patterns are recorded into it, it exceeds the thought process limit of the animal spirits. In other words, it is slightly inferior to Volumen Hydrargyrum in terms of attack power. In exchange, its defense—its function to protect its master fully uses the reflex speed of the animals, so it can’t be broken through with a normal Mystic Code.
When she controls it herself, the prana burden is quite large, but when it’s switched to auto-mode, the prana burden is lessened. It is best described as a Mystic Code whose defensive aspect is more strongly ironed out than its offense.
Incidentally, this is a secret to everyone besides Caules, but Fiore gave each arm the pet names Aster, Blanca, Comet and Wolf respectively.
 MOONLIGHT/LOSTROOM material - Encyclopedia: Chaldeas [Other]
The infinitesimal global environment model. A Mystic code that imitates the soul of the earth.
A hypothesis that the Animusphere family of “Astrology,” one of the Clock Tower’s 12 departments, continued to pursue.
It assumes that the planet possesses a “soul,” and copies that soul, as the “data of another Earth” from a 100 years ahead that is operated as a virtual simulation.
It was launched by Marisbury Animusphere, and since then, Chaldea has guaranteed the future where “civilization still exists even after 100 years” by observing this global model.
It is a mass of information dense enough to have mass, and it is said to be impossible to touch by matter due to their difference of phase.
Animusphere thought that it was impossible to create an “existence that identical to the Earth" from scratch, but it would be possible to copy the soul in its entirety, and he put this in practice. Of course, the content of the “file” cannot be analyzed even if the copy is successful, however, what’s important is the surface of the “copied file.”
There is no need to analyze the content if the goal is to just keep it running. Animusphere activated the duplicated soul of the Earth without any intention of opening its contents, treating it as a simulation tool to observe 100 years into the future. As a result, it is said that once stopped, it will be impossible to restart. After all, nobody knows the structure of its contents.
Since it can be used as an unwavering map of human history, it can also be used as a support system for the Pseudo-Spiritron conversion and transference, Rayshift.
At the start of FGO part two, this treasure of humanity was frozen and sealed by the hands of Lostbelt Servant Anastasia.

Penetrating Blade of Gold [Mystic Code]
A Mystic Code in the form of a dagger, passed down in Gray’s hometown.
According to legend, it was handed down to them by the Black Madonna, to be kept until the time of King Arthur’s return. The blade itself possesses the ability to separate the mind and soul from the flesh. It was intended to separate Gray’s mind and soul from her body, allowing the spirit of King Arthur to inhabit her body in the final stages of the ritual.

 Fate/Apocrypha material - Encyclopedia: Shisigou Kairi [Person's name], p.170-171 [T]
Kairi Sisigou [Person's name]
One of the Masters of the Red Camp. However, he chose to act independently with his Servant without joining Shirou Kotomine’s group. His Servant is Saber of Red, Mordred. His fiendish appearance is just like that of an American outlaw. He isn’t a magus, but rather a magecraft user. Though he can’t match magi in terms of knowledge, he ranks equally in terms of battle experience with Darnic who has survived for a hundred years.
He normally wanders from battlefield to battlefield recovering the corpses of magi and plundering their Magic Crests. Fundamentally, he intentionally acts so as not to increase the number of casualties. This is because causalities are always appearing somewhere in the world every day and night even without him doing anything.
He habitually uses a sawed-off (meaning with a shortened barrel) shotgun as a Mystic Code, but he only uses it as medium for the Gandr spell and doesn’t use it in its original purpose as a gun. Also, he fundamentally uses things like hand grenades made out of hearts, animal eyeballs and monkey hands as part of his necromancy, so the majority of his Mystic Codes are in extreme bad taste.
He chose to participate in the Great Holy Grail War after receiving a request from the Association of Magi. Originally, he had planned to fight alongside the other Red Servants, but he chose to take independent action due to not being able to trust Shirou Kotomine and his Servant Semiramis. He and Saber engaged in skirmishes with the Black Servants and won against Berserker of Black, but then they noticed the scheme of the Red Master Shirou Kotomine and decided to put the war on hold.
However, they still fought to obtain the Holy Grail right till the very end, but they dropped out of the Great Holy Grail War when Mordred and Semiramis dealt mutually fatal strikes against each other. The actions that Shishigou took to save Mordred also backfired on him and caused him to die.
The sole thing decided about the two of them from the initial plotting stages was that they would “rampage around as they like without regretting anything and fight and fight until they die while smiling” as “this story’s Bonnie and Clyde”. Well, Bonnie and Clyde didn’t die while smiling, though.
In the past, Shishigou’s talent as a magus was first-rate, but is now second-rate. As a magecraft user, he is first-rate. As a Master, well, I suppose he gets a passing mark for having well managed Mo-san, who is quite tricky and difficult to deal with, without once antagonizing her.
He seems to have poured a lot of affection towards his stepdaughter whose name was never revealed in the story, and if you search the back pockets of his jacket, you can fight an old photo of the two of them together there. However, his appearance became fiendish after he began going out to battlefields, so his face in the photo is very much that of a serious scholar.
If Mordred ever saw that photo, she would first laugh for a while, but then she would understand the unpleasant truth about it and turn silent. In other words, she would realize his unbelievable despair of having chosen a wound-filled life that made the man into that photo turn into the person in front of her.
The wish that Shishigou had for the Holy Grail was actually something truly acute. Somewhere in his heart, he thought that the wish that he publicly spoke of wasn’t true, but that his real wish was simply to undo the death of his stepdaughter.
The moment he realized and accepted that, everything about Shishigou’s life as a magus reached its end.
Furthermore, in the initial plot, Shishigou Kairi was descended from the family that Darnic chased out. However, it created a contradiction chronologically and the plot wasn’t that entwined with Yggdmillennia in the first place, so it was easily discarded.

Thompson Center Arms Contender Custom [Armament]
The customized firearm that Emiya Kiritsugu uses as a mystic code. It is a single-shot pistol originally developed for use in hunting and competitions. The barrel can be easily switched out, allowing it to be used with a large variety of bullet calibers. By fitting it with a handmade barrel forged using magical processes, and using special bullets that contain his own powdered ribs, Kiritsugu has transformed it into a deadly anti-magus weapon. Well, that's the short version; for a significantly more long winded explanation please refer to volume 2.
Incidentally, this gun was actually what made me want to write a story like Fate/Zero in the first place. In a way, you could say it was the start of everything. Or more specifically, it was Lance Henriksen's performance in Hard Target. I guess what I'm trying to say is, thank you so much, Mr. John Woo. Stranglehold was really fun. Will there be flying doves in Red Wall, too?
 Lord El-Melloi II Case Files material - Encyclopedia: Melvin Weins [Person], p.110
Melvin Weins [Person]
The Tuner of Garbage. Or, the garbage Tuner.
The second word to come out of his mouth is always “Mama.” The third is “women.” The fourth is “Money,” but before he can get to his fifth, he’ll start vomiting blood. Truly, from the bottom of his heart, a useless magus.
At present, he is the only one remaining who refers to El-Melloi II by the name of Waver.
Though his skill as a Tuner of Magic Crests is legendary, it was never something he wanted. His persistent habit of vomiting blood isn’t a gag at all. Without his magical hematopoietic medicine, it would be an ordeal to survive even a single day with his body.
As a result, the proper use of his Magic Circuits was rather difficult, so even though he had the talent to reach the rank of Brand, he retired from the competitive life of a magus early. After that many people, including his own father, deserted him.
But as a result, perhaps as some strange coincidence, he learned of his extraordinary talent for manipulating the Magical Circuits and thus Magic Crests of others. The father that deserted him returned with nothing but smiles, and many times more people than left him flocked to his side.
But, after going out to meet the returning crowd, Melvin had changed a little.
“This isn’t because of my environment or anything. I was a monster like this right from the beginning.”
So he says, but there was no doubt he began to test those around him more after that incident. This happened around the same time he lent Waver the money to visit the Far East after he bragged about turning the Clock Tower upside down.
His mother is a powerful woman, who even that Magdanel acknowledges. Even when Melvin’s father abandoned him, his mother stayed by his side. The tools he uses for his Tuning work that he carries around everywhere were all put together by his mother. The strangely high price for them on the Rail Zeppelin stems from the fact they are a Mystic Code of the Renaissance era, and possess a level of precision difficult to reproduce in the current age.
Though his first appearance was at the end of Volume 4, he existed in the proposal document written up a year prior to the release of Volume 1, acting together with Gray as the deciding factors for the direction Case Files would take. If Gray is a character symbolizing the present day El-Melloi II, then Melvin is the character that symbolizes his past.

An imitation created by Flat at the behest of El-Melloi II after he analyzed the spell and Mystic Code used by Atram. As a result, Caules was able to awaken his own talent for Electricity Magecraft, which he was most compatible with.
Because there was no patent for the batteries, there was no problem between them and the Faculty of Law, but Reines’ concern shown by her complaint of “don’t come crying to me when they murder you over it” was perhaps natural.

 Fate/Zero material - Encyclopedia: Volumen Hydrargyrum [Magecraft], p.092
Volumen Hydrargyrum [Magecraft]
One of the mystic codes employed by Lord El-Melloi. Essentially, it is a mass of magically-infused mercury that has been filled with a large variety of movement patterns and programmed to respond appropriately depending on the situation. I guess you could call it a kind of battle golem? Out of all of Kayneth's armaments, it has the greatest capacity for physical destruction. He had prepared many other mystic codes designed for battles with curses and conjurations, but the vast majority of them were lost when his hotel was blown up by Kiritsugu.
Though it wouldn't be wrong to call it an almighty weapon due to its versatility, in the end it is still just an automaton, and once you see through its movement patterns it's fairly easy to handle. Also, since the magical energy required to operate it is directly proportional to the complexity of its shape, it is necessary to keep it in its basic form as much as possible – switching to a more complex form drastically reduces its reaction speed and power. The final "sea urchin" transformation used in the battle against Kiritsugu was a form that combined both raw defensive ability and cunning, but accordingly the drain on Kayneth's magical energy was immense.
By the way, after the war ended Lord El-Melloi II may or may not have reprogrammed this mystic code and employed it as a multi-purpose maid golem. Though it has enough intellectual capacity to perform simple household chores, it seems there's a troublesome bug that pops up every now and then that causes it to rampage around insisting that it's a killer robot from the future. Maybe it was shown a detrimental movie just when it was on the verge of completing its education in good taste…?
 Lord El-Melloi II Case Files material - Encyclopedia: Cigars [Mystic Code], p.106
Cigars [Mystic Code]
One of the few Mystic Codes carried by El-Melloi II. The tobacco inside was specially put together by El-Melloi II himself. There are many varieties, from those used for defence, for setting up Bounded Fields, for stabilizing the mind, and for activating Magic Circuits.
As to why he decided on cigars, after being forced into the position of El-Melloi II, a panicked Waver Velvet was searching for some way to make himself look more Lord-like, to which some drunk magus mentioned that “A cigar and a suit are a man’s weapons.” Or something like that.
