Jin spent the next few months training with Beerus and Whis. During the day he would spar with them making lots of progress very quickly, which startled them a lot
When it was night time, he would teleport back home and have dinner with Bulma and her family, or sometimes just with Bulma
He also introduced Bulma to 21 who got on great together, considering the fact that they were both geniuses, and would often talk about their work and Jin.... not that he knew about the last one
One year later
Jin was sparring with Beerus who could tell that Jin's strength was constantly increasing, in every moment that they collided. Beerus had never been this excited before as he had heard about the Super Saiyan God, a while ago, and was sure that at one point Jin would be that god and could challenge him
Jin placed right hand up into the air and created thousands of balls of ki, and then brought it down, which sent all of the ki blasts straight towards Beerus who would dodge of punch them out of the way
Although he wouldn't admit it, he found the balls of ki quite hard to deflect. All throughout the time that Jin was fighting against Beerus and Whis, he refused to enter Super Saiyan and would be hell bent on increasing his strength in his base form, and after a year of fighting against Beerus and Whis, and learning their techniques, he managed to take his base form up to 800 million
Whis: That will be enough for today's training
Jin: Okay Uncle Whis
Jin floated down towards the ground, along with Beerus who looked quite content after today's spar, and was looking forward towards Jin's food
Everyday Jin would cook for Beerus and Whis, which over a year, had improved Beerus's attitude, as he wasn't as grumpy as in the anime, and thanks to Jin's people skills, he had improved his standing within Beerus's mind, who didn't think of him as just a chef, but as a student, and a godson
Jin's skill in cooking had massively increased, even though he thought it to be already at its peak. He would be able top cook quicker and would make better tasting food
Beerus: Jin is... amazing
Whis: Yes, yes he is. Although I can tell that he's been hiding his true strength, for some reason he refuses to bring it out
Beerus: Knowing him he probably has a good reason. He's very smart for his age, especially for a Saiyan, he wouldn't hold back for no reason
Whis: My my, I've never heard you give anyone praise like that
Beerus: Well why wouldn't I, he's my star student
Whis: He's your only student....
Whis deadpanned, causing Beerus to just grumble. Whis however knew that Beerus spoke the truth as Jin proved himself time and time again. In both strength and intelligence, which is rare for people. He was glad that he got to train someone like Jin, who would understand all of his teachings and would actually listen to his instructions
A few months ago Whis was truly shocked as he found out that Jin had mastered Ki control, and wouldn't leak out even a drop of it. This caused him to be very curious as to how strong Jin was, and what techniques he had, resulting in them constantly sparring
As they were both speaking to each other outside they were interrupted by a very delicious smell, causing them to quickly head towards their dining room, and eagerly awaited to be served by Jin
Jin: Here you go
Jin placed their chicken parmesan down on the table and took off his apron and headed to him room. Seeing this they couldn't help but feel a bit sad, as they wouldn't see Jin for a while, well at least Beerus wouldn't, Whis planned on going with him on his trip, after he got permission from Beerus of course
Jin walked to his room and got changed, before heading back to Beerus and Whis, and told them that he'd be heading home, and would be back in the morning for the trip
Beerus said his goodbyes to Jin and said he'd be waiting for him to get stronger and fight him again... and also eat more of his cooking later on
When Jin teleported back Beerus had a solemn look on his face and stared straight into his meal. Whis seeing this only sighed, as he knew what he was thinking about. After getting used to having Jin around for so long, they began to dote on him, and even became his god parents
A few months ago when Jin was training with them, they asked him what had happened to his parents, and he told them that they were killed by Frieza. Beerus, not caring about other Saiyans, couldn't help but feel very guilty at Jin's parents death, as he was the one to order Frieza to destroy the planet
Whis: Sigh... Your gonna have to tell him someday
Beerus: ... I know...
Meanwhile at the Briefs home, Jin returned and found that 21 was helping to set up dinner in the house. This was nothing unusual as she would stop by often for dinner, asfter making a good impression on the Briefs, and especially with Panchy, who was Jin's only mother figure
During dinner
Panchy: So 21, how's your work going?
21: Its going very well Mrs Briefs, although Dr Gero has been acting quite odd recently
Jin: How so?
21: He's been speaking about creating androids to help the world, however it seems as though there's an ulterior motive hidden behind his words
Mr Briefs: Well I'm sure he's just stressed from all the work, and could do with a good rest
21: I guess your right...
Bulma: So Jin, how's everything going with your training with Beerus and Whis
Jin: It's going quite well, I've gotten much stronger than before, much stronger than Frieza
Tights: Well that's amazing, now there's nothing to be afraid about, and we can rest easy
Jin: I would love to share that enthusiasm you have Tights, it's just that there are stronger beings than Frieza, like his brother and father, and then there are other being that are hidden on other planets, and I have no doubt that they'll arrive here one day. As much as I'd love a peaceful life with the people I care about, I need to keep getting stronger
Mr Briefs: And we are all very grateful for that Jin
Bulma/21: Yep/Yes
Jin: I uhhh I also have something that I'd like to speak to you all about
Bulma: What is it?
Jin: Sigh... I plan on leaving.... this universe tomorrow
Everything went as quiet as the grave the moment he said those words. Bulma looked at him and began to have tears in her eyes, as did 21
Bulma/21: I'll come with you!
They both said at the same time causing Jin to chuckle slightly, before he spoke again
Jin: You don't have to worry, I plan on coming back of course, this is my home, I'm only going for a few weeks, just to check out a few things
