Eternal Fighter Zero: Memorial

In Eternal Fighter ZERO, there is no overlying storyline or reason for fighting; it is simply a dream battle between Key's most beloved female characters. The backgrounds are faithful renditions of important locations within the original games, and the entire soundtrack is based on remixed BGMs from the original games. As much as EFZ is based off characters from visual novels, many of the characters' moves and abilities are parodies from other fighting games, like Guilty Gear, Street Fighter, and The King of Fighters.
