Written and illustrated by Naoko Takeuchi, "Sailor Moon" was serialized in the monthly manga anthology "Nakayoshi" from December 28, 1991 to February 3, 1997. The side-stories were serialized simultaneously in "RunRun"—another of Kodansha's manga magazines. The 52 individual chapters were published in 18 "tankōbon" volumes by Kodansha from July 6, 1992, to April 4, 1997. In 2003, the chapters were re-released in a collection of 12 "shinzōban" volumes to coincide with the release of the live-action series. The manga was retitled "Pretty Guardian Sailor Moon" and included new cover art, and revised dialogue and illustrations. The ten individual short stories were also released in two volumes. In 2013, the chapters were once again re-released in 10 "kanzenban" volumes to commemorate the manga's 20th anniversary, which includes digitally remastered artwork, new covers and color artwork from its "Nakayoshi" run. The books have been enlarged from the typical Japanese manga size to A5. The short stories were republished in two volumes, with the order of the stories shuffled. "Codename: Sailor V" was also included in the third edition.
