Karas is a Japanese six-part original video animation series. Tatsunoko Productions produced it to commemorate its 40th anniversary of anime production. Each Karas episode was first televised in Japan as a pay-per-view program from March 25, 2005, to August 3, 2007, before being released onto DVDs. Manga Entertainment compiled and released these episodes as two feature length, direct-to-DVD films for the English market.
