Ever since they encountered aliens on the moon, humanity's technology has developed by leaps and bounds. Half a century later, even though most have it easy, Robby Yaji and Hacchi Kita cannot seem to catch a break in this advanced society. Robby—a man perpetually struck by misfortune—owes large sums of money to debt collectors due to his poor investments in shady get-rich-quick schemes, and Hacchi finds it difficult to get over the boredom of his mundane life. The two end up on an adventure of a lifetime when loan shark boss Yang sends Hacchi to collect the money Robby owes. Rather than pay up, Robby blasts off into space and heads to Isekandar, a planet that supposedly brings happiness to anyone who visits. Seeing a chance for some much needed excitement, Hacchi tags along with Robby on this journey filled with alien encounters, giant robot battles, and all sorts of troublemaking—all the while avoiding Yang and his cronies who are desperately combing the universe to find them.

Iwaki Tomonori is an average 15-year-old boy who likes older women. He happens to have a crush on his teacher, but soon thereafter, learns she has become engaged. He heads home brokenhearted, only to find a 12-year-old girl named Rizel at his home, who he learns the Japanese government has married him to against his will. Furthermore, he learns Rizel is no ordinary girl; she is a biochemically engineered human, and her creators (her "papa"s, as they are often referred to) promise to waive multiple bills of Iwaki's parents in exchange to be allowed to stay at their house, and thus Iwaki's life with Rizel begins.
