In December 1991 "Nakayoshi" began serializing "Sailor Moon", which became an instant hit. The success encouraged Takeuchi to work on both "Sailor Moon" and "Sailor V" from 1991 to 1997. However, "RunRun" was canceled with the November 1997 issue, and the planned "Sailor V" anime adaptation was canceled with it. During that 6-year period, she produced 52 chapters that were collected in 18 volumes. The success of the manga led to a 200-episode anime adaptation, three animated films, numerous video games, and wide-ranging merchandising.
