Golgo 13
ゴルゴ13
Overview
The "graphic drama" (as described by Saito Productions) which initially premiered in 1971 was produced in the wake of Golgo 13's initial groundswell in popularity from its initial publication in 1968. The anime employed a "scale animation" style whereby the action effects were added onto still and scale images of manga panels prior to filming episodes with sound effects, giving a rough look similar to gekiga manga. In contemporary terms, it's closer to a motion comic with voice acting than a conventional animated work.

Golgo 13 is not his real name. Then again, neither is Duke Togo, Tadashi Togo, or any number of the aliases he goes by. A man of mystery, not even the world’s most prominent intelligence agencies can determine who Golgo really is, or just where he came from. But all agree that his skills are nothing short of legendary. Armed with a custom M16, Golgo is willing to take any job for any agency, from the FBI to the KGB. He has completed every contract he has ever taken and will work for anyone who can meet his price. He is both the greatest weapon and the greatest threat to any nation; no one is safe once they are in Golgo’s sights.

As the pair travel from town to town, defeating youma along the way, more about Clare's organization and her fellow warriors comes to light.
