Chapter 1:Prologue
It has been one year since the Z-fighters defeated Buu. Peace has spread throughout the universe. Everybody has grown older and developed new ways of life. Everybody lived peacefully . However peace will not be kept for long. Goku is the only one to know this.
He has learned about this secret when he left after the Cell Games, when he went to see Grand Kai. During the 7 years that Goku was away, he learned that he had another brother. Goku was shocked at the news. According to the Kai he was supposedly as strong as Goku in strength and speed. Goku got excited as per usual, but he learned a terrible twist to the reunion.
His brother was actually traveling the universe on his way to destroy him. Goku couldn't believe that his own brother was on his way to kill him. It was not like he was shocked because it already happened do to the Radditz situation. However, Goku knew that this would be the ultimate battle.
The good news to all this is the fact that his brother would not be there for quite sometime, so Goku had awhile to go before his brother would show up.
Now it is one year after the battle with Buu.

He has ravaged the universe hopeing that he found the reason why he was there. To find his brother was his only mission in life. His name is Sirus.
