CosmoWarrior Zero

At the end of the 30th century, humanity has spread to Andromeda — but the mechanized beings it created have revolted and enslaved their creators. Zero is a commander in the independent Fleet, what remains of Earth's armed forces. The war with the humanoids has cost him his family, and fighting them is all he has left. Then he receives orders to hunt down Captain Harlock — the space pirate said to be allied with the machines. The problem: Harlock was Zero's mentor, and he only attacks mechanical-men ships. Determined to find the truth, Zero accepts the mission anyway. He navigates constant friction between the human and machine members of his crew, develops feelings for his first officer Marina Oki, and gradually comes to understand that Harlock and the situation around him are considerably more complicated than the orders he was given.
