Career Kazuma Kamachi has stated that ever since he was a child, he had always wanted to become a novelist, spending his student days in trying to achieve this dream. However, his intention was never to become a popular writer. From the time he was in junior high school, bit-by-bit he started writing, but it was not until he graduated from high school that he ever completed any of his work. Despite this, his work caught the attention of editor-in-charge of the award, Kazuma Miki, who offered him a chance to write another work. and made his debut with A Certain Magical Index in April 2004 after 6 or 7 revisions. The initial volume was written as a complete story in case that it would not sell;

He states that many of his pre-debut works, including the prototypes he sent to Miki, remain stored away at his house.
