Captain Harlock Season 3 Episode 3 Arcadia: The Secret Story of Its Construction (English Subtitled)

"We're all as one, together on the Arcadia."The Arcadia is rapidly being repaired on a Pirate Island while Lafresia continues her bloodthirsty hunt for it. While this is happening, Harlock tells Tadashi the secret story behind the Arcadia's origins. As fate would have it, Commander Kiruta captured and enlisted the services of a brilliant scientist named Tochiro to build a battleship to help capture Captain Harlock. However, Harlock saves Tochiro after he is in a pinch on Heavy Meldar, a planet which was being cultivated and they escape on the newly built Arcadia. Though it was a close call, they escape, but Tochiro (is hit with a bullet and) dies right after. Emeralda, wishing to remain with Tochiro, entrusts their daughter, Mayu, to Harlock. She then follows Tochiro out into space in a burial at space sea.
