Kamachi Kazuma

Kamachi Kazuma (鎌池和馬) is a Japanese light novel author and the original creator of the Toaru Majutsu no Index light novel series and its spin-off manga series, Toaru Kagaku no Railgun, Toaru Kagaku no Accelerator, and Astral Buddy. He also actively works on the manga and anime adaptations of Index, Railgun, and Accelerator and has worked on other related media such the original plot of the PSP games.

As he uses a pen name, his real name and identity is as of yet unknown.

Career
Before becoming the famous writer of the Index light novel series, Kamachi wrote a story titled Schrödinger's City (シュレディンガーの街) as an entry in the 9th Dengeki Game Novel Prize in 2002. Unfortunately, his submission failed to pass the third selection stage. However, his story caught the attention of the editor-in-chief of Dengeki, and Kamachi later became in-charge of writing the book Want to Try Writing (書いてみないか？), which later became his debut as a professional writer.

Background
Kamachi's identity has been shrouded in mystery. He has little to no media exposure, and like many novelists uses an avatar — a face created from simple shapes like circles or oblongs — as a picture in his publications, often describing himself as: "a new author hoping to take the most unmotivated author picture in the world"; which was his self-introduction in his debut work. Haimura Kiyotaka, the illustrator of the Toaru Majutsu no Index light novels has once described him as "delicately sports-minded", while the author of the Toradora! light novels,, upon meeting the author personally was surprised to discover him as "younger than expected".

Kamachi began writing novels while he was still studying as a junior high school student. However, his works were not finished until he graduated from high school.

Work
Kamachi considers writing novels as his pastime, and he takes joy in doing so. In fact, he is noted for his very quick pace of writing. This exemplified by volume 2 of the Index novels which was written at the behest of his editor, and was forced to complete it in 17 days. He is also extremely prolific, apparently managing to write for two of his light novel series on schedule, and at the same time writing for other side projects. Indeed, even Miki Kazuma, editor of the Toaru Majutsu no Index novels has noted the amount of output he has in his autobiography.

On holidays, he plans on the progress of the plot and prepares manuscripts. Kamachi also takes some time to research on materials for the light novels.

Trivia

 * Kamachi once used a picture of an orange with a face on it, all made using circles or other shapes, as an avatar during the first five volumes of the Toaru Majutsu no Index light novels. Since Volume 06, he has switched to a much simpler avatar: various faces created from circles and/or rectangles.
 * As of New Testament, Kamachi began using various photos as an avatar instead of simple shapes.
 * His real life identity is still unknown.
 * According to the Heavy Object A manga series, Kamachi voiced one of two unnamed soldiers in episode 16 of the Heavy Object anime.
