Falchion is an ace pilot in the Space Defense Force, and the pilot of a space ship known as Divine. On his way back to his home planet, daydreaming about girls, Divine's computer picks up a transmission from a nearby planet. Answering the transmission, it turns out to be a distress call from a beautiful woman on the Water Planet. "Save me..." she pleads, "and I will lend you my power." Falchion, lonely bachelor in space that he is, can't say no to a pretty face, and flies off towards the Water Planet.
