How did dragon ball characters ended up in YOUR UNIVERSE

Sora, Goofy, Donald, and you were chilling in Traverse town trying to relax before going up to your new adventure, as you waited outside as Sora stocked up on potions, ethers, etc, etc and getting weapons for Donald and Goofy.

While you waited outside you stared at the night sky seeing the stars that shimmered in the sky, they looked like diamonds but out of reach. The stars are the silent witnesses of eternity, their light a testament to the patience of the universe.

As you thought about the stars you were suddenly snapped out of your thoughts by a loud thuds and sounds of boxes breaking in the small but short alleyway, you went to investigate only to find dragon ball characters

You would stare at them in silence as they stared back at you, crap you have dragon ball characters that you need to look after for, not only that their God of destruction, Beerus along with attendant angel attendant Whis were here! Now you know this is gonna be the longest day of your whole life.
