Captain Harlock

It is the 30th century, humankind has already successfully established various space colonies across the universe. Technology has advanced to a point where various necessary job roles have been abolished. The vast majority of humans have since engaged at entertainment activities instead of doing something work productive. All seems well until a mysterious alien force known as the Mazon invade Earth, and very few humans react to this threat all except for a teenage boy named Tadashi Daiba. When Tadashi failed to find any help from the military forces, he turns his attention to an outlaw space pirate crew known as the Arcadia Pirates led by the courageous Captain Harlock. This makeshift crew of renegades are the only chance that the Earth has in defeating the Mazon.
