Capsule Corporation Building

Goten and Trunks were currently sparring in the large backyard as Piccolo watched them exchange blows, sitting down with his usual serious facial expression

Goten: I've gotten stronger, Trunks!!

Trunks: We'll see about that, Goten!!

The two leaped back and skidded across the ground before dashing towards each other with their fists reeled back

Piccolo: Keep it up you two!

The two were about to clash when suddenly a bunch of tiny particles of green energy began to gather up in the sky, eventually The Grand Priest along with 64 unconscious students and a couple of teachers appeared in the sky and fell to the ground, catching Trunks, Goten and Piccolo by surprise

Tokoyami: Ugh...Perfect Landing...

Piccolo: G-G-GRAND PRIEST?!?!

Goten: Look at all those people...!

Trunks: I see tails on a couple of them...are they Saiyans...?!

Piccolo: Wait...I know these kids...these are the kids who were always with Y/N...!

Grand Priest: Please allow me to explain...

After The Grand Priest explained everything to Piccolo, he had a pretty good grasp on the situation, most of the others had woken up as well

Piccolo: So your little school had been blown up by a powerful new threat...and you had nowhere else to go...did I get everything...?

Grand Priest: Yes, Y/N instructed me to bring everyone here since he knew you'd all be here.

Yang: Okay now that we're safe, CAN SOMEBODY PLEASE EXPLAIN?!?!?!

Everyone turned towards Yang as Piccolo was about to speak up, suddenly a small portal opened beside The Grand Priest as you came flying out of it

Y/N: What the hell?! I could've sworn I had my landings down pact...

Everyone: Y/N!!

Y/N: Yeah it's me, you guys thought I died or something?

You were about to explain a few things when the back door of the Capsule Corp Building suddenly opened, revealing Bulma who walked outside

Bulma: What's with all that yelling?! My baby daughter is trying to—Eeek!

She stopped her sentence when she noticed just how many people were outside, she almost immediately recognized you as she ran over to you

Bulma: Y/N! What brings you here?! Is something bad going on?!

Y/N: As a matter of fact Bulma, there is...is Vegeta home...?

Bulma: Hmph! Of course not! He's out with Goku training again! Those Saiyans are really getting on my last nerve!!

Y/N: Alright, I should be able to track them down in a snap, Grand Priest, can you summon the Gods and Angels here?

Grand Priest: Yes, but what's your goal from brining them here...?

Y/N: I have a plan, and they're all essential for it to work...

Grand Priest: I see, I'll summon them here at once...

Y/N: And Bulma, You're haven't waste all your money yet, Right?

Bulma: Of Course not!

Y/N: Good, can you let my classmates stay here for the time being? There has to be a big room in there somewhere.

Bulma: Well...Yeah! Our largest room is free right now!

Y/N: Good, Thanks Bulma! You're a life saver!

You suddenly turned around and began to walk away, This caught Yang's attention as she shouted to you

Yang: Hey! Where are you going?!

Y/N: I'm going to gather some people who can help us! Bulma will guide you to where you'll be staying for now! I'll be back I promise!

With that you leaped into the air and flew off, off to find Goku and Vegeta

Meanwhile

Goku and Vegeta were out in the wild plains, training in an intense sparring match just like Goten and Trunks were when everyone arrived

Vegeta: I won't lose this time, Kakarot!!

Goku: I'm getting excited, Vegeta!!

The two continued to spar as you were approaching the area, the two Saiyans in your sight as you disappeared and reappeared closer to them

Y/N: Well Well, Training as usual I see...

The two Saiyans suddenly turned around to see you floating there and watching them, both going wide eyed and quickly flying to you

Goku: Y/N! You're back in our world!

Vegeta: I'm assuming you graduated from
That weird academy...?

Y/N: To Goku's Question, Yes, for Vegeta's Question, No, The academy was blown up by a dangerous new threat, it's the reason that we came here...

Vegeta: "We"...?

Y/N: I don't have time to explain, I need you guys to do me a favor, gather up all the Z Fighters and tell them to go to Capsule Corporation, I have a plan, but we're gonna need help, and lots of it...

Goku: Right! This has to be a real serious threat if you had to come back here...c'mon Vegeta!

With that the two of them flew off to find the rest of the Z Fighters, you decided to head back to Capsule Corporation and check to see how everyone else is doing

Time Skip

You we're just arriving at The Capsule Corporation Building as you spotted the Kai's, Gods of Destruction, and Angels for each Universe out at the front of the building

Y/N: Good, he managed to gather the gods around...

You descended back to the ground as you landed on your feet and walked towards the gods

Grand Priest: Just in time, did you find Goku and Vegeta?

Y/N: Yes, they're gonna gather the strongest warriors on this planet to help out...

Beerus: Y/N, what's going on here? If this is some new threat then you should learn to handle yourself, not rely on the gods...

Y/N: You'll just have to trust me in this one...please come with me everyone, I have a LOT of people to explain this to...

With that the Gods and Angels followed you into the building as you eventually reached the biggest room in the structure, which was a large dome with grass and trees, everyone had woken up at this point and were quite confused

Y/N: We have robots to make you some food to your liking, along with some beverages, please help yourself while you're waiting...

You then turned around and looked at the ceiling, a drop of sweat running down your face

Y/N: Now, once the Z Fighters get here I can explain just what's going on...
