Monochrome Factor is a Japanese manga series written and illustrated by Kaili Sorano. It was first serialized in Mag Garden's bi-monthly manga magazine Comic Blade Masamune in May 2004. However, when the magazine ceased publication, the manga began serialization in the new and revamped magazine, Comic Blade Avarus, in September 2007. The manga is licensed for distribution in North America by Tokyopop, and has so far released four volumes, with the latest having been released on December 2, 2008. An anime adaptation produced by GENCO, and animated by A.C.G.T, premiered on Japan's terrestrial television network TV Tokyo on April 7, 2008. It also aired on other networks such as AT-X and TV Osaka, though the episodes aired on TV Tokyo first. The anime has shōnen-ai themes which are almost completely absent from the manga.
