DDD

A mystery novel written by Nasu with illustations by Koyama Hirokazu that was first published in Kodansha's Faust (released three times a year) in 2004, stories included "J the E." and "HandS."

The novel was later re-published by Kodansha under the Kodansha Box imprint in 2007. After the release of DDD volume 2 in August 2007, fans have been eagerly waiting for volume 3, which seems to be nowhere near finished at the moment.
