Sister Princess
is a Japanese magazine published by ASCII Media Works (formerly MediaWorks) and sold monthly on the thirtieth that primarily contains information on bishōjo games, but also includes an entire section on anime based on bishōjo games, and serializes manga and light novels based on such games. The "G's" in the title stands for "Gals" and "Games". The magazine is known for hosting reader participation games whose outcome is directly influenced by the people who read the magazine; such games include "Sister Princess", and "Strawberry Panic!". "Dengeki G's Magazine" first went on sale on 26 December 1992 with the February 1993 issue under the title "Dengeki PC Engine", which changed to the current title in 2002. A special edition spin-off version called "Dengeki G's Festival!" is published in irregular intervals and each issue focuses on a specific bishōjo game. Four other special edition versions under the "Festival!" name are "Dengeki G's Festival! Comic", "Dengeki G's Festival! Deluxe", "Dengeki G's Festival! Anime", and "Dengeki Festival! Heaven". "Dengeki G's Magazine"'s sister magazine is "Dengeki Girl's Style", which publishes information on otome games, targeted towards females.
