On May 1, 2000, an issue of the manga was released as an original video animation through VHS. Produced by Maxell e-cube and distributed by Art Port, the release format was called "manga video", which consists of the original manga images with sound effects and dubbing added. It was followed by an anime television series produced by Magic Bus and broadcast by AT-X in 2002. Most voice actors of the "manga video" were replaced for the anime, except for Susumu Chiba who played the role of Ryo Utsugi. As the manga was still unfinished, Nagai allowed the anime staff to create its own end. Nagai also commented the thirty-year gap between the manga publication and an anime adaptation was because the audience was not prepared for it.
