Chapter Navigation N/A Prologue Chapter 1


On the eve of July 19, after a series of normal events, a boy named Kamijou Touma finds himself running for his life as a group of thugs chase him for a few kilometers into the streets of Academy City. What became a gentlemanly gesture towards a seemingly helpless middle-school girl ends up with him getting rescued by said girl, named Misaka Mikoto, a Level 5 esper with the ability to control electricity.

Touma's accidentally mocking words force an encounter between a "worthless" Level 0 and one of the few Level 5 espers in Academy City. However, due to a power that resides in his right hand, the Imagine Breaker, he was able to withstand Mikoto's abilities.

Despite this, however, he considers himself truly unlucky.
