~Prologue~

After the Buu Saga, the Z-fighters settled down. Though they kept up their training and trained as hard as they could, there was no immediate threat to the earth. The z-fighters were glad that there was no present danger. They had time to live their lives and win tournaments. But not every thing was the way it was before. Goku and Vegeta kept sensing a strong power in the sky, as if there was a portal that was going to open. After a few months of keeping tabs on this new feeling, they felt it getting stronger one day. Both Goku and Vegeta were very busy so they sent up Piccolo to check it out and to make sure that nothing bad was going to happen. Piccolo, also feeling this strong power, agreed to check it out. So he flew up to the spot where the power came from and studied it. He flew as if he were sitting on something and just stared at the spot. A couple hours later, he saw something in the sky in front of him. Piccolo came to a standing position in the air and went to his battle stance expecting the unexpected. There was a portal growing bigger and bigger as he stared at it. About 10 minutes later it was just as big as he was. Then he felt the ki of two beings. Just then he saw one thing jump out of the portal...it was falling in the air and he flew down after it and caught it. He looked back up and noticed another thing fall out of the portal. He grabbed that also. He then looked in his hands to find two of the most beautiful women he has ever seen. Piccolo then hurried to Gokus house to show him and Vegeta what fell out of the portal.
