Mystic Eyes

Mystic Eyes (魔眼) grants the power to interfere with the outer world. Acquisition of Mystic Eyes happens when there is some sort of mutation in the Magic Circuits located in the area around one’s eyes. Mutations like that can be done artificially through a process similar to forging a Thaumaturgical Crest. Mystic Eyes usually work like Single Action spells and are activated through the use of prana. The proof of a first-class magus since it grants great power while being easy to conceal.

Known common types of Mystic Eyes

 * Binding (束縛): The most common Mystic Eyes, casts a suggestion spell that cripples the target upon eye contact. Weakness is that user becomes vulnerable to similar eye contact-based effects during the moment of casting. Effects can be negated by running prana through the Magic Circuits. Illyasviel von Einzbern has these eyes.
 * Charm (魅惑): casting of a spell that distorts the target's perception so that he sees the caster as someone of great sex appeal; seemingly it only works with members of the opposite sex. Diarmuid Ua Duibhne's Mystic Face skill worked under similar concepts as these Mystic Eyes.
 * Compulsion (強制)
 * Contract (契約)
 * Distortion (歪曲): Creates an axis of revolution in a certain area of space. A variation of it, Refraction, allows one to change the trajectory of flying objects, even those with great supernatural power such as Black Keys and the hair of Tohno Akiha. The eyes of Asagami Fujino.
 * Enchantment (魅了): The eyes possessed by most vampires, capable of high-level hypnosis. Classified as Gold under the Noble Colors system. Well demonstrated in Tsukihime: Dark Kiss Mark. (Satsuki Bad End). Satsuki, despite being a newborn vampire, is capable of hypnotizing Shiki to ignore the dead bodies of his entire class.
 * Flame (炎焼):
 * Illusion (幻覚)
 * Jinx (凶運)
 * Whisper (暗示): Allows for simple hypnotic suggestions.

As stated before, it is possible to artificially manufacture Mystic Eyes by altering the Magic Circuits located in one’s eyes. However, only Mystic Eyes of the Binding, Charm and Whisper types can be produced like this. On the other hand, while inborn Mystic Eyes are rare, there are known cases of it happening and they are said to be powerful enough to intervene in destiny itself.

Ciel possess an unspecified Mystic Eye, thanks to either her abilities as a mage or as one who was once Roa. Its powers resembles that of Whisper or Enchantment-types and allows her to hypnotize people into believing what she says to an extent. She is not capable of implanting memories directly, but rather merely causes someone to rationalize memories to fit the scenario she states. Unfortunately, the spell has flaws that make possible for it to be rejected. For instance, if Ciel were to reference something that her target knows to be false, it would cause the hypnosis to be broken. Furthermore, she is either incapable of or unwilling to erase Shiki's memories of herself.

Asagami Fujino is a special case since her Mystic Eyes were the result of her family’s psychic ability evolving to a point that it is in par with Magecraft. Still, this raises the possibility that other Mystic Eyes are also just a powerful type of psychic ability.

Special Mystic Eyes
Besides the ones mentioned above, there are cases of Mystic Eyes truly unique in power. Among them include:


 * The unnamed eyes possessed by Balor, the ancient Celtic god of darkness and great-grandfather of Cú Chulainn. It is the predecessor of Shiki Tohno’s Eyes of Death Perception. It could actualize the death of the target by just glaring at him.
 * The (unnamed) supreme Mystic Eyes that Brunestud of the Crimson Moon had. They were designated as Rainbow under the Noble Colors system.
 * The unnamed eyes possessed by Roa. Similar to Mystic Eyes of Death Perception (see below), and originally falsely considered as ones, they are fundamentally different in effect. Though Roa believed they were a result of his numerous contacts with death due to his reincarnation ability, they in fact originated from his host, SHIKI Tohno. They allowed Roa to see and destroy the life of other living beings.

Cybele
The Mystic Eyes of Petrification (石化の魔眼), possesed by Medusa.

Petrification sorcery is no strange thing for modern Thaumaturgy, even if its users are rare and few in numbers. However, Mystic Eyes capable of petrifying others are something that nobody, human or not, has in the present era. Designated as Jewel under the Noble Colors system, they surpass the Gold-ranked Eyes of the Dead Apostles and are exclusively possessed by Holy Spirits and Demonic Beasts from the Age of Gods. It affects all targets within the owner’s field of vision, regardless of whether said targets are looking at the Eyes or not. Those who possess Rank C or lower in Mana will be immediately petrified, while those with Rank B may or may not be affected depending of the conditions. Those with Rank A or higher won’t be petrified, but will sustain "pressure" from the Eyes and receive a one rank-down to all parameters.

Pure Eyes
淨眼 - Jougan

Known also as Eyes of Purity, they are the ability to see that which normally cannot be seen. A somewhat weaker form of Mystic Eyes, but among those who are born with special eyes these are a more common occurrence and are something that saints would possess. Strictly speaking, Tohno Shiki’s eyes should fall on the Pure Eyes category, but because they give the power to interfere with death and not just see it they are considered true Mystic Eyes.

Pure Eyes by characters:


 * Nanaya Kiri – To perceive people’s thoughts in the form of waves. Granted him limited psycho-empathy and detection capabilities. Also allowed him to identify inhuman beings through the color of their waves as normal humans had colorless waves.
 * Nanaya Shiki - To see the things that are not supposed to be seen. Allowed Shiki to perceive Tohno Akiha's Origami, when Akiha herself could not see it for herself. Its unique characteristic eventually allowed Shiki to acquire Mystic Eyes of Death Perception after a near-death experience.

Mystic Face
