From the introduction: Welcome to planet Earth, Jumper. Or a very different version of it, where dinosaurs and animal-men walk side by side with ordinary humans without much fuss or explanation. There are many strange and wonderful things here, from a Red Ribbon Army seeking to take over the world, to a powerful demon from another world sealed within a rice cooker somewhere in the ocean. Beyond all of that are the seven Dragon Balls, which when gathered, will grant the user one wish before being scattered across the world once again. The year is Age 749, and one week after your arrival, young Bulma Briefs will meet a strange boy with a monkey tail named Son Goku, starting a journey to search for the Dragon Balls and a legacy that will carry on through the ages. You will be staying until Age 759, two years after the birth of Goku’s son, Gohan, if you do not change history.
