25 Episode Mechanime from 1984, directed by Ryosuke Takahashi of Dougram, VOTOMS and SPT Blue Comet Layzner fame.

This is probably the only anime opening that can be classified as belonging to the genre of New Wave, most other contemporaries relying more on contemporary idol-kayo or J-Rock.

The song is "Galient World" by Eurox - the band was involved in the production of Akina Nakamori's Fushigi, which is an excellent, unique and atmospheric 80s J-Pop album, and indeed one of my favorites among Japanese music.
