This game is actually closer to a graphic novel, as the plot revolves around a demon, and your only real choiceis what victim he is to attack at the moment. Like many AIL games, this one was also made into a hentai anime, in this case,one that was called "Maniax." That particular anime contains the same characters as this game, but the rather extreme scenes in the anime are not in the game itself, which contains pretty standard hentai content.
