Goten came back from school, tired but determined to train because the new world tournament was coming up. He came up to his dad Goku and asked him "Dad, can you train me?" he asked innocently Goku finishing up his 8th bowl of rice looked up and said "Sure, I was looking for a good partner"
10 minutes later the fight starts, Goku lands the first punch and a quick ki blast, Goten dodges the blast and goes for a barrage of kicks and punches making Goku himself a run for his money. "Wow, you've been training Goten" A couple of weeks back Goten found more confidence in himself and trained hard with Piccolo, he also learned new tricks "Special Beam Cannon!" Goten yelled out of his lungs and shot at Goku. Meanwhile Goku wide eyed dodged and went super saiyan, he then quickly used solar flare and used that time effectively to charge a kamehameha. Goten was blinded bu went super and charged up his own kamehameha for a clash.
Feeling outnumbered, Goten screamed "Kaioken x3", then Goku lots balance, not because of his power but because of the fact that he knows the technuiqe
"wow Goten you sure got strong but not a lot"
"dad I have an idea"
"Huh?"
"I want to leave the juniors division"
"so you mean you want to use the time chamber?"
"Yes"
And so they travelled to kami's lookout.
