S1·E28 The Ulysses Nebula

The human race started with two."In order to rescue Mayu, Harlock allows the will of the ship to choose its own course. It then sets course for the Human Planet within the seven planets of the Ulysses Nebula. Dr. Ain and thirty humans escaped to there. It's almost like a tropical paradise. Harlock and the crew are there to take respite but when they hear that many UFO's have been spotted overhead recently, they go off to investigate. But, the Mazone have reached there as well and Harlock and the crew are attacked. Miyu, who pretended to be one of them but is really a Mazone, threatens Dr. Ain and make him use his weather control device to create a massive storm. Because of this, the only people who are left in the village are the two young children Vena and Ikaru.
