Goten was staying at Capsule Corporation before he left so when he came back he continued to stay there.
And the reason is very simple. Bulma has tons of resources that he can use. Whether it is books and equipment for studying or ideal training tools and rooms for fighting.
"Knock. Knock."
He heard a knocking on the door.
He opened the door to see Trunks and Mai.
"Want to grab a bite." Trunks said to Goten.
Goten went out with Marron and Bra yesterday so he does not want to go out but he decided that he should spend some time with his so-called best friend outside of fighting.
"Fine but your treat," Goten said to Trunks.
------------------------------
At the restaurant.
"Orange juice! Again? It seems like you didn't change during these four years." Trunks said.
"Something like a favourite drink doesn't change just because I was unable to drink it for a while." Goten refuted.
"But sometimes your taste changes because of your age. I mean I was unable to drink coffee when I was 8 but now I am addicted to it." Trunks said.
"Don't say stupid things. I know you." Goten said.
"Huh. What do you mean by that?" Mai asked Goten as she widened her eyes to figure out more about Trunks.
Goten knows that Trunks only started to drink coffee to appear more mature and impress Mai.
And Goten still knew that Trunks didn't like drinking coffee just from looking at his expression.
Goten then picked up a Strawberry Daifuku that was in front of him and put it into his mouth.
--------------------------
At Night Goten has to prepare for his studies.
He went away for four years so there are tons of schoolwork that he has to catch up to.
He would have ignored all of those if he could but he didn't want to make his mom sad.
He has no plans to slack off from his training but he knows that he has to focus on his studies for a while.
---------------------------
A few months after Goten fought Beerus.
"You have improved a lot," Goten said as he spared with Gohan while Trunks watched the fight on the sidelines while holding a little black hair girl in his arms.
It was Pan. The daughter of Gohan and Videl.
Both Goten and Gohan are using their God forms.
The two were almost evenly matched in their God forms with Goten having an advantage over Gohan.
But Goten was not going all out.
He could stack Ultimate on top of Super Saiyan God if he wanted which would widen the gap between him and Gohan.
If Goten used his Ultimate Super Saiyan 4 with God ki the gap between them would be even wider but the motive of the spar was not to beat Gohan up.
It's to fight on an equal field and try to draw out the power that lies even beyond that of Super Saiyan God.
Goten realized that Gohan using Super Saiyan God is strong.
If Gohan fought Beerus he would have done almost as well as him when he was using Super Saiyan God. Goten concluded.
Then suddenly both Goten and Gohan saw a glimpse of the power that was beyond that of the Super Saiyan God as their fist clashed.
The two stopped sparring for a moment to figure out what just happened.
But the colour that they saw was not blue. And not only that both of them saw different colors from one another.
"Another form?" Trunks said as he looked at the sky where Goten and Gohan were at. Pan clapped her hands as she also saw what happened.
With his Super Saiyan Rage, he thought he had caught up to Super Saiyan God Goten and Gohan but it appears that there is still a power gap that he still couldn't close.
But this time he was not sad anymore. He has to keep fighting and keep training.
He is hopeful. And his willpower is stronger than it ever was.
---------------------------
On the unknown planet where Beerus lived.
Goku and Vegeta were trying to land a hit on Whis who was effortlessly dodging both of their attacks with the use of a power called ultra instinct.
The two of them have grown stronger by leaps and bounds compared to a few months ago under the guise of Whis.
They were now able to wield God Ki and were even able to use the power of Super Saiyan God.
Just like Goten and Gohan, Goku and Vegeta are also searching for the next step after the God form.
Beerus looked at the two from afar.
He was not impressed as Goten was still stronger than both of them when he used his full power.
--------------------------
However, the earth warriors are not the only ones that are training as in a spaceship that is wandering in the middle of the universe an enemy of Goku was already planning his return.
"Lord Frieza." A short blue alien called Sorbet called out to the Space Tyrant Fireza who once threatened the entire universe before his defeat at the hands of Son Goku.
"What.... Can't you see that I am still training?" Frieza said.
"It's an emergency. We have received communication from the lord Cooler. Your elder brother." Sorbet said to Frieza.
"Cooler. Isn't he supposed to be on the other side of the universe just like my useless son?" Frieza said.
"You have a son lord Fireza," Sorbet asked.
"Don't mention about him. He is a disappointment." Frieza said.
"What did my brother want?" Frieza asked.
"He said that he heard about your defeat and wanted to see how strong the person that killed his little brother was," Sorbet reported.
"Hmm. Tell him that I will personally meet him. Using his army to invade the earth would increase my chances of Victory if the Buu rumour turned out to be true." Frieza said.
Unknown to everyone on Earth Fireza was planning his move and his army was bigger than ever accompanied by two of the most powerful beings in the universe.
