Witch

A Witch (魔女) is a term used to describe certain magic users, usually female, who have been active and often persecuted throughout history.

Principles
Witches are part of the cause why the anti-magical culture of England has developed unnaturally and thus the reason why Necessarius was created. From their persecution, it could be inferred that some of their magic practices defy the teachings of the church, even though it has been stated that their magic doesn't come from unnatural rituals such as cooking unbaptized babies nor something along those lines.

There are certain traditions and beliefs that have been carried by witches or held concerning them in the past. An example would be the belief of the devil residing in women's hair. A group of witches might be described as a Kavun (カヴン).

It has been noted that contrary to fictional depictions, witches tend not to use wands, apparently because like staffs or clubs, they are symbols of patriarchal power. Although witches are generally female, they are apparently some male witches.

Magic
Much of witchcraft is based on the use of natural chemicals, with potions and ointments created from plant and mineral extracts. The ingredients of a witch's potion (魔女の薬) are not necessarily obscure and at times fairly mundane. The use of medicinal herbs and other plants in their craft has given witches considerable expertise in the field, with it also being noted that they were able to figure out and  on their own.

Witchcraft based on natural potions has been noted to be capable of various feats including healing, divination, cursing, flight etc. A common job for witches has been noted to be controlling nature to help crop growth, with repelling insects being part of it. An ointment derived from bear grease has been noted to be used for insulating skin from cold.

Aside from ointments, there are spells for divination involving fire and water, and wind spells using rope knots. Witches also have their own variant of the curse involving piercing a wax doll with some blood, a fingernail or another part of their target mixed in.

Another common trait associated with witches alongside the brewing of potions is the use of broomsticks to fly. The former is actually responsible for the latter, as a magic potion is applied to the broom in order to grant it the power of flight, and the same ointment can also be applied to other tools or the body to endow the same effect. As with most forms of magical flight in the present day, they are susceptible to common anti-flight spells, so witches in the present have often been shown to fly low when using them to mitigate the danger from a fall should they be brought down.

Besides broomsticks and magic potions for flight typical of witches,  the unit of Anglican witches stationed on the Mobile Fortress Coven Compass possessed spiritual items that allow them to communicate via thought at high speed, spells that have a fire-like light at the tip of their broomsticks shoot a ray of light, and an ocean control spell. How much of this, as well as the Coven Compass itself (which possessed countermeasures against anti-flight spells, a large-scale flash spell, and long-range bombardment),  is based on witchcraft is not known.

Wicca
Wicca is a system of witchcraft which emerged in the 20th century. It was officially announced in 1954, its texts created by, a magical researcher who was said to have dug up pieces of an ancient mythology or religion predating Christianity which ancient witches were said to be priestesses of, from before it was twisted by Christianity, and carefully reproduced the texts from before witches were considered villains, releasing his own collection of self-taught knowledge, doubling as a report on the 'truth' of witches. However, skeptics and others have pointed out that Gardner had a few biases when creating a supposedly 'perfect reproduction' of ancient witches, such as the inclusion of inauthentic sexual ceremonies. It has also been claimed that though witchcraft, its spells, not based on a specific mythology or religion like Greek or Celtic, are something newer, more like superstition, created new by mixing bits of thoroughly Christianized culture instead of digging up ancient techniques.

Central to Wicca is Aradia, or the Gospel of the Witches (アラディア、あるいは魔女の福音). According to this grimoire, all witches' sabbaths are used to worship the goddess Aradia, the supposed daughter of  and, the goddess of all witches, who supposedly took a physical body and descended to the human world to save the poor from the rich, with rituals meant to teach people how to resist oppression from the wealthy and the church. The book is presented as a report on the legend, supposedly conveyed to the author by an Italian witch, however as no mythology has a goddess of that name and given the supposed lineage given in the story, many considered likely that the witch made it up on the spot to match what the author wanted to hear, though Gardner believed it and incorporated the legend of Aradia into Wicca's spells at such a deep level that they could not be removed. In that sense, Aradia is the goddess of all witches - those who practice Wicca can be said to be receiving the blessing of Aradia-born theories and using her techniques.

Wicca has a number of taboos and rules which its modern witches (reproductions of a later era rather than the originals) are bound by, the most prominent being the Sanbai no Hōsoku (三倍の法則) which states that the effects of any magic used by a witch, for a good deed or a bad one, would be returned to them threefold (e.g. if one uses magic to steal money, they would lose thrice as much, and if they use magic to kill, they would receive a wound thrice as lethal). These witches are given a stack of blank paper when they start down their path and write down the knowledge they obtain in it until their death, creating their personal grimoire (though it would be highly unusual for one to reach the level of an original-class grimoire), called the Book of Shadows (影の書). By following the instructions in the Book of Shadows written by each witch, one can use their magic, that of Aradia.

Another deity figure within Wicca is the.

Background
In the past, witches were persecuted by the church, who also spread misinformation to slander them and justify its actions. The witch hunts eventually declined due to criticism.

At the time of the Golden Dawn, there were old witch lodges around who felt their place in the world had been taken by the cabal.

During World War II, witches apparently danced in midwinter forests until they froze to death in an attempt to delay the Third Reich's invasion.

In the present day, there are numerous witches working with the Anglican Church and Necessarius.

Toaru Majutsu no Index Movie: Miracle of Endymion
Witches Marie Spearhead, Mallybath Blackball, and Jane Elves, under the command of Stiyl Magnus, go on a mission to retrieve Meigo Arisa and does battle against Shutaura Sequenzia and her Black Crow Unit. By the climax of the movie, they align themselves with Kamijou Touma's intentions and help prevent the Endymion space elevator from crashing down to earth by releasing its explosive bolts. They later hear the Miracle of Endymion caused by the singing of Arisa and Shutaura as they merge back together. Stiyl carries all three witches as the elevator begins moving.

They later visit and scold Stiyl for the danger he puts himself in as he recovers back in England.

British Royal Family Arc
A unit of Anglican witches stationed on the Mobile Fortress Coven Compass were one of the groups that the Knights of England tried to hunt during Carissa's coup d'état. In the ensuing Battle of Islay, they quickly dispatched 100 witches to repel their attacker.

After fighting off the knights, Kanzaki Kaori mentioned on how Necessarius contacted the Coven Compass, requesting the witches' assistance in weakening the Curtana Original. The witches complied and after the joint operation, Carissa lost half of the power that the Curtana gave her and the Knights of England pretty much lost their Telesma boost.

Not long after damaging the Curtana's power, the witches used the Coven Compass to launch a remote attack on the Buckingham Palace, authorized and made with the consent of third princess Villian, from just outside the UK's national boundaries. The target was at 500 kilometers and the actual estimated "effective" range of the Coven Compass was of approximately 330 km; yet regardless of that difference the attack was successful. The attack was meant to provide enough distraction, as to hamper Carissa's possibilities of doing an open counterattack on the rebel forces that would try to sneak into the palace.

Coronzon Arc
During the invasion of the United Kingdom by the Crowley's Hazards, witches were among the groups stationed on the frontline, attempting to stop the enemies crossing the Strait of Dover from landing.

Christmas Day Arc
During the battle on Christmas Day, St. Germain referred to witches among the groups who had set Anna Sprengel as their goal in the past, along with the Golden Dawn and the.

Los Angeles Arc
Following the events in Los Angeles on December 26th, Anna Sprengel spoke with Aradia, whose name was noted as that of the goddess from a famous witchcraft grimoire and described as a witch of the moon and light.

New Year's Eve Arc
On December 31st, Aradia made extensive use of the Rule of Three, Wiccan magic and other witchcraft during her attempt to kill Kamijou Touma in Shibuya, in the name of resolving the situation surrounding Alice Anotherbible and achieving her goal of saving witches. In the latter part of the day, Aradia's manipulation and proselytizing had converted many people in Shibuya into a new coven of witches, who as well as going after her target were pitted against others induced into a witch hunt by the Bologna Succubus.
