Mystic Eyes

are a form of supernatural power concentrated in the eyes, granting the power to interfere with the outer world through sight alone. 
The Mystic Eyes are the oldest magecraft known to humans, deriving from neither ritual nor study.Lord El-Melloi II Case Files Volume 4: case. Mystic Eyes collection train (Upper) - Chapter 3 Part 1
There exists at least one similar form of ability called , possessed by Diarmuid Ua Duibhne.Fate/Zero Volume 2: The Mad Feast of Kings - Act 8 Part 1 -122:18:42
==Characteristics==
Mystic Eyes usually work like Single Action spells and are activated through the use of magical energy. They are the proof of a first-class magus since it grants great power while being easy to conceal. Since they have their own Magic Circuits, Mystic Eyes are able to produce magical energy and cast spells all on their own.
The mystical significance of Mystic Eyes is old. Sight is considered the first magecraft in human history,Lord El-Melloi II Case Files Volume 4: case. Mystic Eyes collection train (Upper) - Chapter 1 Part 2 because it is the one out of the five senses that provides the most information. As such, many cultures across the world came to fear the , and many mysteries of the natural world were explained through the symbolism of eyes. For example, the Sun and the Moon being often described as the eyes of Heaven. The from Egyptian mythology is a particularly famous example, with the God Horus' right eye being the Sun and his left the Moon. In Christianity, the eyes of the omnipotent God became connected to his providence over all things, becoming the .
Other natural phenomena described using eyes include storms, with things like the "" and the clouds surrounding it called the Eyewall, thus making the storm itself a single eye. From there, the association of wind and storms with divinity creates a connection to the eye as well: the archetypical examples being storm deities Balor of the Evil Eye, king of the Fomorians in Celtic myth, and one-eyed Odin from Norse mythology, with the former having a single eye whose gaze could annihilate entire armies, and the latter who gave up one of his eyes in exchange for omniscient knowledge of all things.
The earth itself has "eyes", like the mouth of volcano, the image of a bright red eye piercing through the darkness of night strongly connected to the image of the evil eye. Though not as numerous as gods of the storm, there are cases where these symbols were granted to Godesses of the Earth: a famous example of this would be the Gorgon Medusa, from Greek mythology. Even in modern times this continues, with the black holes discovered by modern science which could also be said to be eyes born of natural phenomena. There is a conceptual similarity between them and , a manifestation of Shiva in Hindu mythology, to the point black holes could be said to symbolize the magical eye aspect of Shiva on a macro level.
Acquisition of Mystic Eyes happens when there is some sort of natural mutation in the Magic Circuits located in the area around one's eyes. While inborn Mystic Eyes occurring naturally are rare, they are the most powerful types, said to be powerful enough to intervene in destiny itself. Fujino Asagami is a special case since her Mystic Eyes were the result of her family's Psychic ability evolving to a point that it is on par with magecraft. Otherwise, natural Mystic Eyes are considered a powerful type of Psychic ability. So, whether it's a magus or a normal person, though extraordinarily rare, sometimes Mystic Eyes just spontaneously develop in them.Lord El-Melloi II Case Files Volume 4: case. Mystic Eyes collection train (Upper) - Chapter 2 Part 3 
Mutations like those can also be done artificially through some kind of augmentation effect for the eyes using Spiritual Surgery,Kara no Kyoukai Volume 4: Void Shrine (「　　」) - /4 a process similar to forging a Magic Crest, and their creators fetch a high price for their work. Some magi even replace their eyes with chrysobel jewels. However, only artificial Mystic Eyes of charm or suggestion, the Charm and Whisper types, can be produced through these methods, and it's not like their success rate is a hundred percent. 
Therefore, if one wants to gain true Mystic Eyes, there is no option to acquire a transplant except the Rail Zeppelin, the Mystic Eye Collection Train that runs through the forests of Europe, collecting any and all Mystic Eyes. Mystic Eyes are something developed and rooted within one's own body, so even removing them is incredibly difficult. But the Rail Zeppelin is an exception to that, ignoring all problems of physical rejection and the like, and not just extracting them, but capable of transplanting Mystic Eyes directly into a new host without risk of failure.
For those who lack the ability to control their own Mystic Eyes, the Rail Zeppelin is like a savior, since Mystic Eyes are such a complicated organ that using them effectively is beyond the skill of most magi.Lord El-Melloi II Case Files Volume 4: case. Mystic Eyes collection train (Upper) - Chapter 1 Part 3 Indeed, there's no guarantee Mystic Eyes come balanced in terms of magical energy output, or the spells they produce. In the worst case, they can activate all on their own, forcefully drawing the Od from the magus' Magic Circuits against their will. The Rail Zeppelin also invites possessors of strong Mystic Eyes to come sell their eyes, under threat of being killed and having their Mystic Eyes ripped out if they do not comply. 
Another disadvantage of Mystic Eyes is that humans are creatures that depend on information to live, yet are bound by that information until they die. Since vision is the sense that acquires the greatest amount of information, possessing Mystic Eyes means accepting being bound by them. For example, having Mystic Eyes of Precognition means absorbing and never forgetting all the information obtained by sight, leading to information overload.Kara no Kyoukai Future Gospel: recalled out summer - Möbius ring /2 It also means being prisoner of the future perceived.Kara no Kyoukai Future Gospel: recalled out summer - \Gospel of the Future (False)Lord El-Melloi II Case Files Volume 4: case.

Since they are the oldest form of magecraft known to mankind, Mystic Eyes are extremely primitive when thought of as a form of magecraft, as, although they are a powerful Mystery, a number of counter-measures against them have been developed around the world.Lord El-Melloi II Case Files Volume 5: case. Mystic Eyes collection train (Lower) - Chapter 4 Part 3 It is possible to suppress the power of Mystic Eyes with a Mystic Code called . They are commonly made into glasses because Mystic Eyes are a power derived from the oculus. They are able to block more unique ones like Death Perception and Petrification, allowing someone to live a normal life without affecting themselves and those around them with the abilities of their eyes. Those of Shiki Tohno (Remake) prove to be not enough for his Mystic Eyes on occasion, causing him to see death even when wearing them. Mystic Eyes Killers can also protect their wearer from others' Mystic Eyes if their power relies on eye contact, such as Lord El-Melloi II wearing some to defend himself from Faker's Mystic Eyes of Compulsion.Lord El-Melloi II Case Files Volume 4: case. Mystic Eyes collection train (Upper) - Chapter 3 Part 3 
There are also ways to divert Mystic Eyes by use of certain objects like Trisha Fellows' pendant (a ), such methods being called . It uses the "power to be seen", which is inferior in terms of the simple defensive effect compared to directly blocking Mystic Eyes. However, the power to be seen is still the natural enemy of Mystic Eyes, as it can be used to trap them with suggestion.Lord El-Melloi II Case Files Volume 5: case. Mystic Eyes collection train (Lower) - Chapter 4 Part 3 In the case of effects like Petrification, recognition of the nature of the Mystic Eyes weakens the effect they have on targets. It is not enough to render them ineffective, but surprise attacks are not as effective, making the rate at which the effect progresses slower. The target still has to be on their guard, else the effect will be magnified.Fate/stay night - Heaven's Feel route - Day 10: darkwood,sleepingbeauty - Future plans
Both the Lehrman family and Touko Aozaki are shown to be craftsmen unrestricted by the traditional limits in forging Mystic Eyes. The Lehrmans' magecraft allows them to use a specific cut of gemstones to create artificial Mystic Eyes for their own use, even reproduce Noble Colored Mystic Eyes to a degree. Implanting a foreign object into the human body trigger rejection, so there are generations of bodily and brain modification in order to allow Yvette L. Lehrman to handle it.Lord El-Melloi II Case Files Volume 4: case.

Within the Clock Tower, Mystic Eyes have their own system of ranking called . Normal Mystic Eyes shine red or green, strong ones glow a luminous Gold, and Mystic Eyes that fall in the realm of Gods glimmer with multiple colors, like Jewels' or Rainbows.
"A Noble Color is like the movement of the stars compared to normal Magic Circuits" is a common saying in the World of Magecraft. Mystic Eyes that directly intervene with the fates of others are classified as being of a Noble Color, and include Compulsion, Contract, Flame, Illusion, Jinx, Petrification, among others.
Above them, Mystic Eyes ranked Gold or higher often held great magecrafts that had long since been lost to the modern era. Gold-ranked Mystic Eyes can earn a Sealing Designation with one wrong step, and are possessed by the highest class of Dead Apostles.
For Jewel and Rainbow ranks, they are so rare that their very existence is hypothetical and can't even be verified. It is assumed that they don't just possess powerful magecraft, but instead could actualize Mysteries that were otherwise entirely impossible to replicate in any era. They could even be said to be an exercise of the Authority of the Divine. Medusa's Mystic Eyes of Petrification fall under the classification of Jewel, and it is rumored that one of the Lords at the top of their faction may be hiding some Jewel-ranked Mystic Eyes away.
;The Noble Colors (and Mystic Eyes categorized as such) are:
* :
**Crimson Moon's unnamed Mystic Eyes.
**Mystic Eyes of Death Perception.
**Balor's unnamed Mystic Eyes.

;
:Mystic Eyes that allow the user to see visions of the future. When it comes to precognition based only on the Mystic Eyes, they are divided into two categories: Predictive Precognition (Prediction) and Determinative Precognition (Calculation). 
:The great majority possess Predictive Precognition. The person having it has a tremendous ability to remember and calculate everything in the environment using information procession, mixing it together in a coordinated fashion to see a possible future. In other words, it uses as much data as possible from the past and present to predict what is possible in the future. But because that process would be greatly hindered by the personality of the person using it, it mostly happens entirely unconsciously. Shizune Seo, Akira Seo, and Trisha Fellows have this form of Precognition. 
:By contrast, Determinative Precognition is much stranger. The same kind of memory and calculative power is required, but while Predictive Precognition is a passive, defensive process, Determinative Precognition is an assertive, offensive one. Instead of reading a future, it builds one.Kara no Kyoukai Future Gospel: recalled out summer - 3 It seeks to determine which of those possible futures will occur, or even is used to decide which one will come to pass. The user acts themself to determine which future would come about, calculating how one would do so.Kara no Kyoukai Future Gospel: recalled out summer - \Gospel of the Future (False) Determinative Precognition is thus many times more accurate than Predictive Precognition. Once it's been seen, that future is completely fixed. Mitsuru Kamekura possesses such Mystic Eyes.

;
:Mystic Eyes that allow one to see the past. It is the same as Precognition, coming in two forms, Predictive and Determinative, but since the past is already fixed, the distinction between Predictive and Determinative is basically irrelevant. Whether predicting the past based on the results evident in the present, or calculating it based on one's own current perspective, the process is more or less the same.

==Pure Eyes==
, also called Eyes of Purity, are the Psychic ability to see that which normally cannot be seen. They are similar to Mystic Eyes in that both are inheritable, however while Mystic Eyes are traits of the body, something like inheriting the traits of a parent's body, Pure Eyes are like inheriting fate and destiny, the offspring continuing the parent's will and quest. 
Pure Eyes are a more common occurrence than Mystic Eyes and can only be inherited by humans with high spiritual power. They can be said to reflect the parent's karma in the offspring, and they are an ability Saints may often possess.
The Nanaya were able to consistently acquire Pure Eyes by having incestuous relationships. Kiri Nanaya displays the ability to read intentions and emotions through color, and Shiki Tohno (Remake) can see that which is not supposed to be seen, such as Akiha Tohno's Origami. Both his and Shiki Ryougi's Mystic Eyes of Death Perception can be called a hybrid power, combining both Pure Eyes and Mystic Eyes.
===Colors===
As seen by Kiri Nanaya's Pure Eyes, various colors are associated with certain beings.
*Blue - Color of those under Shinto. Judging by Kiri Nanaya's Pure Eyes, there are those in the Demon Hunter Organization who follow its beliefs. Pure Eyes also have this color.
*Silver - Color of those under Shinto. They have yet to appear in any kind of form, but according to Kiri Nanaya there are a few of them in the Demon Hunter Organization.
*Gold - Color representative of the demonic. Arcueid Brunestud (Remake)'s Mystic Eyes turns into this color. Also, Nrvnqsr Chaos's Mystic Eyes were depicted as golden.
*Red - Color representative of the demonic. Judging by Kiri Nanaya's Pure Eyes, those who fall under the classification of 'demon' will likely be inclined towards this color. Similar beings are also likely to possess this color.
