The main character in "A Certain Magical Index" Touma is a level 0 esper with a mysterious power known as "Imaginary Breaker" that can cancel out magical or esper attacks if he uses his right hand.
Due to Imaginary Breaker, his luck is canceled which means he has a string of bad luck. Despite that, he seems to attract most of the girls/women of the series to most of the guys' chagrin.
Touma is a good street fighter due to reasons which are explained in the series.
Lore: He will be in Shin/Neo Tokyo where his bad luck plays a factor in stories that will be untold. When magic and science come together, a story is born.
