Tekkaman Blade 2 Story Info

From my understanding, the 3 Tekkaman Blade 2 movies, are the 6 OAV episodes that were released after the original series. Each movie, which can be purchased from Urban Vision, are comprised of two episodes each.

STAGE 1: The New Generation
Ten years have passed since the original series (known as the US TV series Teknoman) as a new breed of Tekaman face off against their powerful enemy - Radham.
