Juusenki L-Gaim I: Pentagona Window + Lady Gablae

A recap OVA that portrays the second half of the series Heavy Metal L-Gaim. After the credits, there is a short clip animated for the OVA entitled "Pentagona Doors", which is intended to be comic relief.

In the Pentagona System, a young man by the name of Daba Myroad leads a rebellion against Pentagona's leader, Oldna Poseidal. Daba's not alone however, meeting a large number of allies along his journey and having in his possession the powerful L-Gaim, a white Heavy Metal left to him by his father.

A side story taking place somewhere before the second half of the series, prior to Daba acquiring the L-Gaim Mk-II. Daba's comrade Leccee is captured by Poseidal's forces, and Daba and his rebels attempt to save her.

Ken, Joe, and Akira, three high school students, must combine their three mecha into Gekiganger III to defeat the evil Prince Akara and Emperor Hyperion. The OAV is a compilation of the scenes from Nadesico, a new "movie", and is a parody of many mecha series from the 80s.
