The story takes place in old Tokyo, the Tokyo of August-September 1923 (Showa 12). At this moment in time, the city is a mixture of extremes... past and present, rich and poor, good and bad. This is a city where we see both horsecarts and motorcars, swords and pistols, lords and businessmen. A wealthy woman from an upper-class family finds herself attracted to a handsome young man, Taka. He and his younger brother seem to be allied, perhaps not entirely willingly, with some of the city's criminal underground (Yakuza). The lady's lovely young maidservant, Sara, meets him too, and a conflict ensues which can only lead to tragedy, passion, and dishonor. But, as events move on, and the days pass, the viewer sees a terrible date coming closer... that unforgettable day of September 1, 1923, at 11:58, when the Great Kanto Earthquake and tidal wave struck Tokyo, causing the death of almost 100,000 people, one of the greatest disasters in human history.

Despite being a refugee from an extinct planet, having an alcoholic as a father and an airhead for a mother, Maris' biggest problem is that she's a Thanatosian. Considering that Thanatosians are six times stronger than the average Earthling it shouldn't be such a curse, especially in a galaxy where violence is rife. But the accidental destruction she wreaks on everything she touches —even with the exotic alloy restraints she wears— means she's constantly in debt. Every mission she's assigned to by the Inter-Galactic Space Patrol becomes a cash-drain when all the damages are docked from her wage. But when she's selected to rescue the rich and sexy Kogane Maru it's like a dream come true. After setting him free from the terror of his ruthless kidnapper his eternal gratitude will surely guarantee marriage —and an end to all her financial headaches.

After coming across an advertisement about how anyone can lead an invasion force, young Don decides to establish a ragtag squad of his own to conquer the cosmos. Working alongside him are the aloof Pepu and the gaming-obsessed Chiku, though the value of their membership remains somewhat questionable. With his two henchmen by his side, the crew's inexperienced leader sets his sights on their first target: Earth. According to the manuals, Earth should be a simple enough target, but the situation spirals out of control right from the start. As it turns out, convincing over seven billion humans to simply roll over and accept their new overlord is no easy feat. Having been blown off by the entire human species, Don and his squadron touch down on Earth and begin their search for a way to subjugate humanity. However, with their unexpected failure, they face more pressing issues—namely, finding food and paying rent—so their plans for galactic domination will have to be put on hold for a little longer.
