"Pretty Warrior Sailor Moon" consists of five separate seasons: "Sailor Moon", "Sailor Moon R", "Sailor Moon S", "Sailor Moon SuperS", and "Sailor Moon: Sailor Stars". The seasons each roughly correspond to one of the five major story arcs of the manga, following the same general storyline and including most of the same characters. Toei also developed five special animated shorts. The anime series was sold as 20 volumes in Japan. By the end of 1995, each volume had sold approximately 300,000 copies.
