A Psychic (超能力者, Chō Nōryokusha?) refers to one who has a mutation, an Abnormal Ability (異能, Inō?) gained as a result of the brain being able to comprehend a "channel" (common sense, or perception of reality) not native to humans. It is a different type of Mystery than Magecraft, although similar in nature.
Psychic Power (超能力, Chō Nōryoku?), also referred to as Extrasensory Perception (ESP), is a catch-all term to refer to the circuits that cause supernatural phenomena to occur. It is a form of nature interference that to the psychic comes as naturally as breathing. Unlike Magecraft, which can be taught and practiced, inherent ability is an absolute necessity. Psychic powers are the ultimate ability of humans, who have become an existence independent of nature. However, these powers are generally incomparable to the great abilities possessed by Demons or Mixed-Bloods. In the end, they are only human.
Psychic powers only appear by chance, they can be the result of an accident causing a permanent change in the brain, and are limited to one generation, although families such as the Nanaya or Ryougi have discovered ways to keep them perpetuated throughout the generations. Generally, a psychic possesses both a "normal" perception (channel) that allows one to function in society using society's own common sense, as well as an "abnormal" psychic perception (extra channel). However, there rarely exist those who only possess the latter who cannot live within society's rules of common sense, eventually degenerating into what normal people would call murderers. These are known as Unfit Existences (存在不適合者, Sonzai Futekigōsha?) - for example, Fujino Asagami. In order to cure an Unfit Existence so they are able to fully adapt to society, one must remove his or her only channel and take away their ESP; however, doing so permanently is impossible with current technology without destroying the brain entirely. To imitate this purpose of removing their ESP, measures such as removing their sense of pain or Mystic Eye Killers exist.
Mystic Eyes are well-known examples of psychic powers on the level of magecraft; there are methods to artificially induce their formation such as magecraft or vampiric influence, even if the user has no innate ability, though the result will be weaker than an inborn power. The members of the Demon Hunter Organization are also known psychics - refer to that page for specifics.
Note that Touko actually described 'extra senses' as a regression. Modern societies are so complex and contain so much information that normal humans would disregard anything not necessary for them. Those who can see beyond normal perception, on the other hand, will irrevocably record everything in their memories - an information overload.
Clairvoyance (透視能力, Tōshinōryoku?) is the ability to flawlessly perceive and observe the world around them; objects, people, locations, events, with one's mind, with no mistakes and 100% accuracy. Achieved by Fujino Asagami. Possibly related to the Servant skill of the same name.
Masochistic Pneumatic Automatism DiathesisEdit
Masochistic Pneumatic Automatism Diathesis (被虐霊媒体質, Higyaku Reibai Taishitsu?), is the genetic condition of Caren Hortensia, if there is a person nearby who has been possessed by a daemon, her body will mimic the end effects that the daemon possession will eventually have on the possessed human. This ability can't be gained from training since it's purely genetic, which is why people born with these traits are valued by the Church as daemon detectors.
Pure Eyes (淨眼, Jō gan?), also called Eyes of Purity, are the ability to see that which normally cannot be seen. They are similar to Mystic Eyes, and, while both are inheritable, Pure Eyes differ from them.
Precognition (未来視, Miraishi?) is the ability to perceive the future. There are two main types, Future Prediction (未来予測, Mirai Yosoku?) and Future Calculation (未来測定, Mirai Sokutei?), with the majority of users being able to Predict instead of Calculate. There also exists a rare third type known as Divination (予言, Yogen?) that does not require information processing and is considered "true" precognition.
Prediction is the ability to unconsciously gather information and automatically absorbs data about one's surroundings, and comparing it to past events and experiences, to use it to flawlessly predict future events and their outcomes. Touko Aozaki describes it as being the "more human" kind of Precognition.
Calculation, on the other hand, is the ability to purge possibilities from occurring by watching the location of the possible futures, thereby bringing to fruition the events one desires. It can thus be described as forging the path to achieve a desired future, enabling its user to flawlessly calculate and define the future with perfect accuracy. In Mitsuru Kamekura case, his 'Calculation' is limited by his requirement of directly observing the targeted area. It also makes the normally formless and ever-shifting concept of "the future" tangible, making it vulnerable to be killed by Shiki Ryougi's Mystic Eyes of Death Perception.
- Shizune Seo - She is able to "predict" the future of those around her randomly and without prior notice. While she is initially hesitant to use this ability, she eventually accepts it with the help of Mikiya.
- Akira Seo - She is able to "predict" the future based on the past of those she meets.
- Mitsuru Kamekura - His Right Eye was capable of seeing the future he desired, while his Left Eye could see "the path" to achieve that future. This allowed him to actually "calculate" and define the future with a 100% accuracy. As it is a future backed by calculation, gathering the evidence of actions, he had to physically see the target to see the future. A power that exceeds simple prediction; however, it is a contradiction as a future that becomes certain cannot be defined as 'the future', which is by nature uncertain. Shiki remarks that he "can't actually see anything" due to this. When Shiki Ryougi killed the future he envisioned, his abilities were killed as well.
- The "Mother of Mifune" - Unlike others who rely on information processing for seeing the future, the Mother of Mifune is a "real" prophetess who can see the future using "Divination." She generally sees tragedies, and she gives advice on how to avoid those tragedies. Thus, she notes that she is not making accurate predictions, as they can be changed. However, if her advice is not followed, then the tragedy will definitely occur with no exceptions. By the year 2010, she has lost her precognitive ability in her old age.
- Ryougi Shiki under the influence of her self-suggestion - Based on Shizune Seo's remarks, she is assumed to use "divination."
It is said that Servants with a high rank of Clairvoyance are capable of a sort of precognition. Powerful instinct, both naturally and as a Servant skill is also a form of subconscious precognition. Characters who possess such skills are:
- All Servants with the skill Instinct
- Tohno Shiki under pressure of imminent death.
Retrocognition (過去視, Kakoshi?) is the ability to perceive the past.
- Fake Shiki (Plus-Disc) - The ability to see the records (memories) of one's life upon meeting. Also capable of sharing perceptions to an extent.
- Shiki Tohno has displayed a similar ability, having been able to see the past of the original SHIKI Tohno, implied to be due to a telepathic connection established since childhood. This ability mainly took the form of seeing his "death" by SHIKI's hands through his eyes in his memories.
Synchronization (感応能力, Kan'nō Nōryoku?), is the ability of Hisui and Kohaku to transfer energy. This transference of energy is performed by the exchange of bodily fluids, such as another drinking their blood, but it is strongest in the act of intercourse.

Psychic Power [Others]
Abnormal powers. Functions that normal humans do not possess. A kind of circuitry that leads to what are commonly called paranormal activities.
Different from magecraft, inborn talents are absolutely necessary for ESP. Those possessing ESP circuits can induce paranormal phenomenons as naturally as breathing. The ESPers themselves take ESP for granted, and treat it as something they simply "can do". They only realise that they are abnormal after others (who can only comprehend "normal") have pointed it out.
In this story, Asagami Fujino is an ESPer, but since she was tampered with somewhat, her ability falls between ESP and magecraft.
ESP is normally an incidental occurrence, a sudden mutation limited to one generation.
 Kara no Kyoukai Special Pamphlet - Encyclopedia: Spontaneous Combustion [Others], p.037 [T]
Spontaneous Combustion [Others]
The so-called unexplained phenomenon of human combustion.
It was the spell that Kokutou Azaka favoured. However, it was closer to ESP than magecraft. In terms of ESP, it would be called Pyrokinesis.
Spontaneous Combustion is a method of attack that causes the target to self-combust, rather than immolating the target directly.
There are many theories which explain Spontaneous Combustion, Azaka's Spontaneous Combustion can be explained by an amalgamation of the Charged Corpus Theory and the Electromagnetism Theory. The Charged Corpus Theory suggests that the human body produces electrical current during states of psychological arousal which causes Spontaneous Combustion, while the Electromagnetism Theory suggests that Spontaneous Combustion is a result of an increased release of electrons in the atmosphere.
All incantations used to activate Spontaneous Combustion were musical notes, since Azaka comprehended magecraft and combat through music.

Synchronization [Unusual talent]
The ability to sympathize with other people. Putting it simply, it's giving one's own physical strength to somebody else. (Synchronizing with somebody else would be empathy.)
As Kohaku and Hisui are particularly talented sympaths, they don't just give their own physical strength, but also strengthen and support the mental and physical strength of their target.
Also, because this is sympathy and not empathy, even if the target is injured there won't be any feedback for the sympath. In game terms, it's like turning off collision detection.
The method of sympathizing varies depending on the practitioner. For some, it is possible to sympathize regardless of the target's will, while for others some sort of ritual is necessary.
The ritual is a switch on the spiritual plane passed down within a family, to control heretical abilities. It is a mental block implanted in the subconscious that prevents the ability from activating unless certain conditions are met.
…In other words, Hisui's family must have been a bunch of perverts, huh?
