The base story is in a world where ESP exist through drugs and science and magic as used by the churrch.
One day our 'hero', Touma, finds this girl on his balcony. She introduced herself as 'Index' and it seems that her memory has been wiped, and replaced with 103000 volumes of magic.
That aside, Touma can't use any esp himself, because his right hand, Imagine breaker, nullifies anything supernatural.
