Battle Angel, known in Japan as Gunnm(銃夢Ganmu), is an original video animation based on the Battle Angel Alita manga by Yukito Kishiro. The OVA comprises two episodes, Rusty Angel and Tears Sign, that serve as a compressed preview for the manga. They correspond respectively to volumes 1 and 2 of the manga, with some differences. According to Kishiro, only two episodes were originally planned. At the time, he was too busy with the manga "to review the plan cooly", nor was he serious about an anime adaptation. There are no plans to revive the anime.
