Professor Tsuyoshi Daiba. (Professor Drake in English) . Tadashi Daiba's father, an astronomer and scientist.

Tadashi, affected by his father's murder, joined the Arcadia crew to seek his revenge.

. (Alexander Kamerov in English) . The leader of Earth's defense forces, he is Harlock's sworn enemy and will stop at nothing to try to eliminate him. Earlier in his life, Kiruta suffered the loss of his father, a government secret agent, during an ill-fated mission, followed by his mother and his younger sister Tami. Blaming the government for his family's death, he rose through the military ranks in order to effect change for the better and, like Professor Daiba before him, tried in vain to warn the Earth government of the Mazone invasion. Kiruda eventually puts his grudge with Harlock aside and sacrifices himself defending the Arcadia's main computer against Mazone troopers. Throughout the Series, he is constantly concerned with the welfare of Mayu, even going as far as to take a Scorpion sting for her
