Toma Kamijo (Japanese: 上条 当麻, Hepburn: Kamijō Tōma) is a fictional character created by Kazuma Kamachi and first illustrated by Kiyotaka Haimura.

A high school student living in Academy City, Toma possesses a rare ability in his right arm dubbed the Imagine Breaker which allows certain types of power to be nullified at the cost of his luck.

Upon coming into contact with a mysterious nun named Index, Toma is caught in a crossfire between various factions of espers and sorcerers whose goals are deeply rooted on uncovering the City's secrets, and the duo.

The character has been praised by both fans and critics alike for his personality, role in the series' plot, and the way he uses the Imagine Breaker ability.

Despite the fact that he is a level zero (powerless), his right hand has an ability called Imagine Breaker (幻想殺し, Imajin Bureikā, "Illusion/Fantasy Killer"), which allows him to cancel out any other power by touching it.

His memory loss is kept a secret and known only to himself and a few others, including his doctor Heaven Canceller, Terra of the Left, Mikoto Misaka, Fiamma of the Right, Index, Seria Kumokawa, and Misaki Shokuhō.
