Eternal Fighter Zero is a dojin fighting games for Microsoft Windows produced by Twilight Frontier, including characters from the visual novels Moon., One: Kagayaku Kisetsu e, Kanon, and Air. Although the all female cast originates from visual novels, many of the special abilities and the game's system itself draw heavily on many different prominent fighting games such as Street Fighter, King of Fighters and Guilty Gear. The characters' play-styles are tributes not only to the character herself, but also to popular fighting game characters. The plethora of references is due perhaps to the fact that EFZ is a dojin game—a game made by fans for fans.
