Tochiro Oyama

Tochiro Oyama is one of the survivors of Samurai Creek, a town of Japanese immigrants of Gun Frontier who were mysteriously all slaughtered, with only a few exceptions.

Tochiro is also former EDF engineer who wanders bars and the streets of Earth pretending to be a beggar after the Earth has been conquered. During a brawl at a bar he reunites another veteran Captain Harlock.

Tochiro is Harlock's best friend and designer/builder of the space battleship Arcadia. What he lacks in height-which is considerable-he makes up for in brains and sheer tenacity. Despite his general awkwardness around women (which is more or less matched by his enthusiasm for them,) he succeeds in winning the love of fellow space pirate Emeraldas. The two have a child, Mayu, though the pair are in love they are damned to spend their lives apart.
