A 12-episode anime series was released by TV Tokyo in 1997 and was written and directed by Koichi Mashimo and animated by Studio Deen. The series featured music by Yuki Kajiura and was the first time Kajiura and Mashimo worked together and would work together for several more projects over the next several years. The series was very loosely based on the manga featuring Bolt Crank, voiced by Masashi Ebara, as the main character and keeping the fictional currency of Lido. The following year a second 12-episode series, "Eat Man '98" was released, once again animated by Studio Deen and with Ebara reprising his role as Bolt Crank, but under new direction by Toshifumi Kawase.
