A Magic Circle (魔方陣 Mahōjin?) is a design or arrangement constructed to facilitate the use of Magic.


There are various elements which can be used within a magic circle and various forms which they can take - the simplest and first form being that of a lone circle. As the amount of information given to a magic circle has a direct relation with its power, magical symbols like the pentagram, the hexagram, the Star of David, or Seal of Solomon are drawn within the circle for additional effects. Other things and words are written along the circumference of the circle to draw power from what they represent via Idol Theory, like the name of the angel whom the power is borrowed from, the type of element, the amount and quality of Telesma needed and how it's going to be used, etc.[1]

However, as a result, the more complicated a circle is, the more difficult it is to control it. If there's a difference between what the caster intended and what is interpreted incorrectly on the magic circle, the spell will go out of control.[1]

Magic circles can be created through various means, from drawing designs and arranging certain objects,[2] to using the positions of the stars themselves.[3] Although magic circles are often constructed on two-dimensional surfaces, they can also be constructed in three-dimensional space.[4][5]

During the British Halloween, the Anglicans made use of the special railway car on the underground line below Buckingham Palace, with a magic circle specifically designed as a safety device to stabilize the Curtana in the event of the sword's power going out of control, in conjunction with a flash spell from the Coven Compass to cause Carissa's Curtana Original to overload.[11][12][13][14]

While heading for London on horseback during the coup, Elizard thought about the magic circles in the roads which could have boosted her horse's power and shortened her journey, but being under the jurisdiction of the British government would have alerted Carissa and the Knights to her location if she used them.[15] Later, during the Battle of Buckingham Palace, the captive Bayloupe used a marker pen to draw a communication magic circle to contact the other members of New Light.[16]

Numerous magic circles, with elements of both Western Kabbalah and Eastern Taoism, were seen through uses of Rosenthal-style magic during the events surrounding DA, the Hishigata siblings, the Coffins and the Rosenthal Family.[19][20][21][22][23][24][25]



  • One particular magic circle is featured prominently in the anime and manga adaptations of Toaru Majutsu no Index, as well as their promotional materials and related media. It consists of a circle containing a pentagram, with a smaller circle circumscribed by the center of the pentagram. Several sets of letters are arranged around the perimeter of the circle, with crosses separating them. In some versions, two larger concentric circles surrounding the base circle and letters. The sequence of letters is as follows (clockwise); "ISCATC+HFIMMMP+MNIP+MNIA+ICY+ISWS".
