Monster (manga)
Written and illustrated by Naoki Urasawa, "Monster" was published in "Big Comic Original" from December 1994 to December 2001. The 162 chapters were periodically collected into 18 "tankōbon" volumes published by Shogakukan, the first on 30 June 1995 and the last on 28 February 2002. While writing "Monster", Urasawa began the series "20th Century Boys" in 1999, which would continue after "Monster" had finished. "Monster" received a nine-volume "kanzenban" re-release between 30 January and 29 August 2008.
Monster erotica
Scholars have identified erotic elements in horror novels featuring monstrous characters as far back as "Carmilla" (1872) by Sheridan Le Fanu and "Dracula" (1897) by Bram Stoker. Science fiction films sometimes dealt with monsters and sexuality, as in "I Married a Monster From Outer Space"(1958). As a distinct genre, however, monster erotica is a more recent development that found its audience on the internet after 2010. Most erotic monster novels are self-published. In 2013, none of the publishers contacted by "Business Insider" for an article about the genre responded when asked if they had been offered such works.
