Psychic

A Psychic (超能力者) refers to one who was born with a mutation, an abnormal ability (異能) gained as a result of the brain being able to comprehend a 'channel' (common sense) not native to humans.

Psychic Power
超能力 chounouryoku

Also refered to as extrasensory perception, this is a catch-all term to refer to the mutated circuits that cause supernatural phenomena to occur. A form of nature interference that to the psychic comes as easily as breathing. Unlike magecraft, inherent ability is an absolute neccessity. Psychic powers are the ultimate ability to humans, who have become independent of nature. However, this power is still incomparable to the abilities possessed by Demons or hybrids with mixed blood. In the end, they are only human.

Psychic powers only appear by chance as mutations limited to one generation. Generally, one is born with both a 'normal' perception that can allow one to function in society, as well as an 'abnormal' perception; those who only possess the latter are known as an unfit existence (存在不適合者) - for example, Asagami Fujino.

Known Powers
Mystic Eyes are well-known examples of psychic powers on the level of magecraft; only abilities which are not or have not been directly noted to be Mystic Eyes should be placed here. 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 toushi nouryoku

Ability to perceive beyond what is physically possible. Possibly related to the Servant skill of the same name.

Plunder
略奪 ryakudatsu


 * See main article: Origami

The mixed-blood ability of Tohno Akiha to steal the life-force of all living beings within her sight through a cursed field of 'plundering'.

Precognition
未来視 miraishi

Ability to perceive the future.


 * Kuramitsu Merca - His right eye was capable of seeing the 'irrefutable conclusion', actually calculating and defining the future itself. As it is a future backed by calculation, gathering the evidence of actions, he must physically see the target to see the future. A power that exceeds simple precognition; however, it is a contraction 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.
 * "The Mother of Mifune" (Mirai Fukuin) - A simple prophet who neither 'predicts' nor 'calculates', but simply sees the future without any relevant information about the subject. She generally sees tragedies, and gives advice on how to avoid those tragedies. Thus, she notes that she is not making accurate predictions, as it can be changed. However, if her advice is not followed, then the tragedy will definitely occur with no exceptions.
 * Seo Akira - Technically, she is extending her retrocognition to make accurate predictions based on information from the past and present. Thus, seeing a possibility. Seo Shizune possesses a similar ability.

It is said that Servants with a high rank of Clairvoyance are capable of precognition. Powerful instinct, both naturally and as a Servant skill (as exhibited by Ryougi Shiki and Saber, respectively) is also a form of subconscious precognition.

Retrocognition
過去視 kakoshi

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.

Spontaneous Combustion

Kokutou Azaka's magecraft talent, though in her case it is an innate pyrokinetic ability, directly causing the target to combust.
