Kamijou no Touma

The One who Purifies God and Slays Demons, better known as Kamijou no Touma, is a major antagonist in the A Certain Magical Index franchise. He is a malicious entity who is the physical emanation of Touma Kamijou's power, emerging as a result of the damage from the conflict with Coronzon as well as his own regrets and subconscious wishes. Taking most of the Imagine Breaker and his other powers with it, as well as possessing memories which he had lost, the individual attempted to usurp Touma's identity and assert himself as the “real” Touma Kamijou, becoming his arch-nemesis.
