"Imagine Breaker Boy" (幻想殺し (イマジンブレイカー) の少年 Imajin Bureikā no Shōnen?) is the first chapter of Toaru Majutsu no Index manga, released on April 12, 2007.


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.

A widespread blackout shut down most of Touma's appliances, causing most of his food in the fridge to go rancid overnight. To make things worse, Touma is reminded of his constant streak of misfortune — breaking his air conditioner and needing to do supplementary lessons. As he tries to sort things out for the day, he decides to dry out his futon when a foreign-looking nun with a vicious appetite appears hanging on his balcony.
