Harlock Saga is a six-part OVA sequel / remake of the 1978 television series Space Pirate Captain Harlock. It is primarily based on Das Rheingold, the first part of the 1869 German opera Der Ring des Nibelungen by Richard Wagner and makes frequent use of music scores from the opera performed by the Moscow Philharmonic Orchestra. It is the fourth anime adaptation of the Harlock franchise and is the first entry in the series to use CGI.
The following weapons were used in the OVA Harlock Saga:
Alberich uses a Luger P08.
Cosmo Dragoon (custom Cosmo Percussion M78)
Harlock and Tochiro's preferred handgun is the Cosmo Dragoon, a custom variant of the fictional Cosmo Percussion M78 laser pistol modeled after the Colt Dragoon (hence the name). The weapon is one of four or five (the number varies from series to series) unique high-powered pistols built by Tochiro.
Harlock's primary weapon is an laser rifle known as the Gravity Sabre, which doubles as both a stockless laser rifle and a sword. Despite its name, the Gravity Sabre's size and cup hilt cause it to bear a closer resemblance to an 18th century Italian rapier than to a sabre. This is one of the few series where Harlock does not use the Gravity Sabre, and instead leaves it in its holster.
Howa Type 64
Tochiro carries a Howa Type 64 rifle while on the surface of Valhalla.
