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.

The OVA anime release Marriage consists of two 30-minute pieces by Miki Kasamatsu on the topics of love and looking for that special someone. The first deals with a group of young women who, after being out of school for a few years, are beginning to think about settling down. However, there is one member of the group who has no prospects, and Shizuka's friends are worried that her shyness will keep Mr. Right from noticing her beauty and character. They persuade her to join a dating service called The Wedding Club, but when her first match seems to be quite a dud, Shizuka wonders if a trip down the isle just isn't in her future. The second episode is about five sisters, only one of whom isn't married. What's more, the cool Kiyomi seems to have no interest whatsoever in finding a husband. Her sisters have other ideas, though, and when a co-worker asks her out on a date, the women convince the suitor to propose marriage that very night.This is easier said than done, however, as Kiyomi's attitude can be quite intimidating. The young man may not end up following through with the plan, but even if he does there is no guarantee that the headstrong lady in question will say yes.

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.
