Hoshi, daughter of Vegeta and Bulma and Goshe, Daughter of Goku and Chichi are teenagers and best friends. They adore martial arts, much like their fathers and are pretty strong for their age, Though they have a bad habit of getting themselves into trouble. But this time they managed to get themselves into even bigger trouble then they could imagine when they accidently press a button while they are messing around in Bulma's time machine that takes them back in time to before Planet Vegeta was destroyed. Now it's up to the Z fighters to bring the girls back home before the girls get hurt or mess up the time line while the girls are forced to try to get used to life on Frieza's spaceship where almost anything can happen, while trying their best not to mess up the timeline. I'm not really good at summeries but its better than it sounds. In this story GT never occured and Ubb doesnt exist.
