Elements (元素, Genso?) are the basic substances that shape the World and play an important role in Magecraft.


Depending on the teachings of Magecraft schools, one could classify everything of reality into different sets of Elements. The four classical elements (Fire, Water, Earth and Wind) are said to came from Arche in ancient Greece. The Mage's Association adds in Void (Ether) and some other elements to make their classification more practical. Besides, there are the Five Elements in oriental philosophies (Water, Fire, Earth, Wood and Metal) and Twelve Constellations.[1] In the Mage's Association, they call Fire normal and Wind noble.[2]

Elemental AffinityEdit

A Magus normally has the capacity to manipulate at least one of the Elements. However, there are cases of those who can manipulate Elements that are completely different from any of the ones specified above. Within the Mage’s Association, individuals like these tend to either very selective houses or not be part of the Association at all. Cases of a magus who possesses more than one Elemental Affinity, and even affinity to Compound Elements, are also known. Usually said individuals try to master spells that make use of more than one Element at the same time (ex: “liquid manipulation” through the use of Water and Wind Elements). Those capable of manipulating all the five Elements receive the title of Average One and are highly valued by the Mage’s Association. Methods to change one’s Elemental Affinity exist, but they are very painful and dangerous.[3]

Known ElementsEdit

Five Great ElementsEdit


Fire (火, Hi?) – One of the Five Great Elements (五大元素, Go Dai Genso?).[3] Spells of the Fire element are related to consumption, heat, entropy, fuels, energy transfer and thermodynamics. This Element has Warm and Dry features. Paracelsus assigned a red color to it following Tattva.[9]


Earth (地, Chi?) – One of the Five Great Elements.[3] Earth element spells relate to grounding, cultivation of energy and energy embedding. This Element has Cold and Dry features. Paracelsus assigned a yellow color to it following Tattva.[9]


Water (水, Mizu?) – One of the Five Great Elements.[3] Related to flows, forms, cycles, combinations and manipulations. This Element has Cold and Wet features. Paracelsus assigned a silver color to it following Tattva.[9]


Wind (風, Kaze?) – One of the Five Great Elements.[3] Deals with air, kinetic forces, static energy, free energy and directed movement. This Element has Warm and Wet features. Paracelsus assigned a blue color to it following Tattva.[9]


Ether (エーテル, Ēteru?) or Void (空, ?) is one of the Five Great Elements,[3] and also the Fifth Imaginary Factor (第五架空要素, Daigo Kakū Yōso?) according to the teachings of the Mage’s Association. It combines itself with any of the other four Elements in order to actualize the mysteries of Thaumaturgy.[10] It is artificial magical energy that forms the basis of modern magecraft, although it did not exist during the Age of Gods. Although amorphous and incapable of materializing by its own power, it is what allows shapeless bodies to take a material form. Paracelsus assigned a black-purple color to it following Tattva.[9]

Ether ClumpEdit

Ether Clump (エーテル塊, Ēteru Kai?, Liquid Clay) is a failed materialization attempt of Ether through the combination with one of other Elements.[10] Under normal circumstances Ether can only be materialized after combining itself with one of the other Elements. In some cases however, mainly when there is some sort of failure on the part of the Magus, it will take the physical shape of a clay-like substance. Other than serving as a conductor of magical energy, it is completely useless. Whatever the shape it is given by a magus, if left inactive for long enough (i.e. without magical energy running through it) it will eventually return to its original clay-like form. Known uses include True Assassin’s Zabaniya, the first suitcase puppet of Touko Aozaki, Cornelius Alba’s slime familiars and the main component forming Leysritt’s body. Somewhat related to the First Magic.[10]

Imaginary ElementsEdit

There are two so-called Imaginary Elements (架空元素, Kakū Genso?).[3]


Hollow (虚, Kyo?), also called Imaginary Numbers (虚数, Kyosū?) is an Imaginary Element that lets those who wield it as their Affinity the power to use Imaginary Number Space. Lainur used it as a time capsule and Trisha put her head into it when killed to keep her killer from using her Mystic Eyes. As a Sorcery Trait, it is a power highly effective against spiritual beings, but not so potent against those whose body is not made out of Ether.[11] When the Matou clan restraining spells are used along with this, it is possible to imprison and skewer the target into a separate dimension composed entirely of shadows. Furthermore, when Angra Mainyu's power is imbued on Sakura Matou, she is able to use this ability even against normal humans.


Nothingness (無, Mu?) is the second Imaginary Element. ​​​​​​In magery, it is defined as that "which is not possible, but materializes", contrasting Hollow which is defined as that "which is possible but not in the physical plane". It has a different meaning than the "nothing" of physics and math.[3]

Known FactorsEdit

Human's FactorsEdit

Factors of human beings are Body, Mind and Soul. Alchemists of Atlas can set all three Factors of theirs as an arithmetic unit to accelerate themselves.


The Fifth Imaginary Factor (第五架空要素, Daigo Kakū Yōso?). See the above section 'Ether'.

True EtherEdit

True Ether (真エーテル, Shin Ēteru?), otherwise known as the Fifth True Theoretical Factor (第五真説要素, Daigo Shin Setsu Yōso?), is magical energy from the Age of Gods. It is also described to form the nine heavenly bodies that gave birth to the planet. Although it does not exist in modern times, True Ether, which was of a far higher quality than ether, permeated the Earth in ancient times. Gods, as well as nature itself, were formed out of True Ether. The natural enemy of the Fifth Imaginary Factor (Ether), bullets of Black Barrel are composed of this substance.


Grain (ジン, Jin?, Gin), or Space Dust (宇宙塵, Uchūjin?). The general term given to the toxic particles overflowing in the Earth of Over Count 1999, after the world lost its capacities to sustain life. Also called “ether” because even though poisonous, it promoted the surface of mutated life forms: the A-Rays, Liners and the Ether Liners.

The rate of energy transfer within the Grain-rich atmosphere is astonishing. A factor that resulted into the arise of a new method of combat that would not be possible in the old world. In a battle between A-Rays capable of absorbing Grain and Ether Liners wielding Knight Arms made of crystallized Grain, the power of conventional weapons is rendered useless.

Supposedly, Grain is the base component of all heavenly bodies. Therefore, the closer is the connection between a life form and its mother planet the greater will be the amount of Ether in their bodies. The greatest example of this would be the Ultimate One, the supreme existence of each respective’s planets and true avatars of their will.

Its antithesis is the True Ether or Black Barrel, which destroys Grain and anything containing Grain on contact.


The Sixth Imaginary Factor (第六架空要素, Dairoku Kakū Yōso?) , also known as Daemon[12], is a force that reacts to the desires of humans and births Daemons out of their wishes. It needs a form, invented by humans, similarly to how it happens to higher-level spirits, in order to materialize itself, as a passive existence. This passive existence is an individual daemon and not a true daemon[13].

But regardless of the result, as a rule, daemons are gentle. They are the Imaginary Factor that understands one's pain and attempts to remove it. Depending on perspective, one can say that they are allies of humanity. They use Reality Marbles[14] as their Alien Common Sense.

Medusa's Mystic Eyes are made from the Sixth Imaginary Factor.
