Kinoko Nasu, the mastermind behind the story of Tsukihime and Fate/stay night, is also the author of the novel Kara no Kyoukai (of which a featured film was recently announced [1]). However, Kara no Kyoukai was not Nasu's only novel. On January 9th, Kodansha released volume 1 [2] of Nasu's other novel, DDD [3], under its Kodansha BOX imprint [4].
The story of DDD was originally published in the magazine Faust. DDD volume 1 includes "J the E" (Faust September issue 2004), "HandS. (R)" (Faust November issue 2005) and "HandS. (L)" (Faust December issue 2005), and a new story titled "formaal hunt." The release of the novel was highly anticipated by Type-Moon fans, even Kodansha BOX's Editor-in-Chief praised the novel [5] by saying: "This person (Nasu), is a genius!" More English information on DDD can be found here [6].
