Toma Kamijo

The main protagonist of Toaru Majutsu no Index and a supporting character in Toaru Kagaku no Railgun. He has the lowest psychic rank possible at Level 0—largely because the people testing psychic abilities cannot detect or classify his abilities. His power is Imagine Breaker, a power which negates all magic, psychic, or divine powers but also his own good luck. Due to the nature of his power, the founder of Academy City considers him neither a Psychic nor a Magician but rather a normal person with a unique ability. He tends to stay away from trouble but possesses a strong sense of justice, albeit somewhat shallow and dogmatic. He is a smart student and knowledgeable about certain subjects yet is a failure in his esper studies. While he is an idealist for the hopes of other people, ironically he is cynical about himself possibly because of his powers.
