The Dragon of Saint George as depicted in a painting of the legend.

This article refers to the reiterating term. For the entity and organization, see Aiwass.

Dragon is a recurring term that appears in several instances in Toaru Majutsu no Index. Most notably, it is the name that Aiwass uses to refer to himself[1], and the organization that is formed around his presence.[2]


The dragon is fantastical creature of legend and is said to have guarded treasures or brought about massacre, and represents respectively, the dragon serving God's angels or the devil. St. George was said to have slain a dragon.

Other legendsEdit

Other legends related to the dragon are seen several times in the novels:

  • St. Martha is said to have subdued a dragon using a prayer full of compassion and love.[3]
  • St. Matthew is said to have defeated two dragons using just a cross and prayer.[4]
  • One of Biagio Busoni's cross-related magic is the expansion of a cross, based on the legend of St. Margaret who was said to have been swallowed by a dragon and expanded the cross to stab the dragon from the inside.[5]


Toaru Majutsu no IndexEdit

Index ArcEdit

Main article: Index Arc

The first instance of dragons being referenced is during Kamijou Touma's first fight with Stiyl Magnus, the word that was used to describe Touma negating Stiyl's flame sword is tornado, which literally means "winding dragon" in Japanese.[6]

Later, during Index's rampage after getting her John's Pen Mode activated to attack Touma. Here, Index uses St. George's Sanctuary named after St. George to distort the space between her and Touma. She later uses Dragon's Breath against Touma, which according to the possessed Index is the most suitable spell against Touma's Imagine Breaker. Indeed, Touma could not fully dispel the attack and required the help of Stiyl Magnus and Kanzaki Kaori to defeat John's Pen Mode Index.[7]

The Dragon King's head that appears on Touma's right arm.

One of the most notable reference to the dragon in the series is the transparent Dragon King's head that appeared in place of Touma's right arm after being severed by Aureolus Izzard. According to Stiyl Magnus, the Dragon King may have been what Aureolus Izzard imagined in the eleventh hour after Touma used fear to disrupt his Ars Magna. Touma's right arm is later reattached by Heaven Canceler. After a talk with Stiyl, Touma wondered if the Dragon King's head was really created by what Aureolus thought or if it was unrelated to the Ars Magna, but he immediately discarded this option thinking it was impossible.[8]

The 7th Index Light Novel Volume, has Tatemiya Saiji reference a dragon that Kanzaki Kaori defeated on her own in order to fulfill a child's wish, and is referred to being able to swallow an entire mountain.[4] In all adaptations of the story arc the depictions are different. In the second season of the animated series, the dragon takes the form of multi-tentacled monster or perhaps a multi-headed serpent similar to the Yamata no Orochi. In the manga adaptation, it takes the form a single-headed giant serpent. Regardless, Kaori defeats the dragon, but at the great cost of having her comrades decimated in the battle. This is one of the reasons why she left the Amakusa-Style Remix of Church.[4]

The arrival of Saint George prepared to defeat the Dragon as depicted in a painting of the legend.

The word Dragon is referenced several times during the arc in the form of the retelling of the legend of St. George. During William Orwell's confrontation against the Knight Leader the latter declares himself as someone who symbolizes a dragon, the Knight Leader quietly noticed that in the values of the Christian Church, the dragon was the symbol of more than one thing. For example, it represented pagans and foreign invading forces, but it also represented a fallen angel stained with evil. [9]

Daihasei Festival ArcEdit

Main article: Daihasei Festival Arc (Railgun)

Eight dragons emerge from Kamijou Touma's severed right arm to end the experiment and save both Misaka Mikoto and Academy City.

In an attempt of stopping Misaka Mikoto while her powers were rising to Level 6 from firing a giant black sphere, Touma, as Sogiita Gunha was holding her back, tried to negate it with his Imagine Breaker, but his right arm was ripped by the great resistance opposed by the sphere. Immediately afterward, a Dragon King's head, the same that appeared in the fight against Aureolus Izzard from Touma's severed arm, came out from the wound, this time showing a long neck. Thereupon, seven other dragons each different in its own appearance accompanied it to stop the power from being unleashed by destroying the black sphere of destruction and releasing Mikoto from the effects of Mental Out connecting her to the Misaka Network. Touma's right arm later reattached or regrew by itself. As both Mikoto and Gunha saw the dragons, this proves that the Dragon King's head wasn't merely imagined by Aureolus.[10]

Other appearancesEdit
