Touma Kamijou is an ordinary high-school student living in Academy City, a state-of-the-art city dedicated to the scientific study of humans with Psychic Powers. Every single student is given an "Esper Rank" to indicate their power and Touma is the lowest of the low: a Level 0 with no psychic talent whatsoever. The only thing he has going for him is his right hand: the Imagine Breaker, which has the ability to dispel any and all supernatural phenomena but also negates his own luck.
