Company: Gekkan Dengeki Comic Gao! x3w6o

Gekkan Dengeki Comic Gao! was a Japanese shounen manga magazine that primarily contained manga and information about series featuring bishoujo characters. It was published from December 1992 to February 2008 by Dengeki Bunko label. The magazine was sold every month on the twenty-seventh.

When Dengeki Comic Gao! was first published, many of the manga that ran in the magazine had transferred from Dengeki Daiou was much more popular, and in response, Dengeki Comic Gao! was reformatted starting with the February 2007 issue on December 27, 2006. This was also when the Gao as printed on the magazine cover was changed from being spelled in katakana to being spelled in English stylised as gao. On December 9, 2006, the first issue of a special edition version of Dengeki Comic Gao! called Comic Sylph was published, and is sold quarterly; starting with volume six, Comic Sylph became a special edition version of Dengeki Daiou on March 21, 2008.

The last issue, nicknamed Gao! The Final!!, was sold on February 27, 2008 with most of the currently serialised titles reaching their final chapters, while some others will continue publication in MediaWorks' similarly themed magazine Dengeki Daiou.
