The Other U7 Supreme Kais as Refugees

[Almighty Majin]

With the reveal of multiple universes existing, we saw how each of those universes had their own gods just like Universe 7. What was odd however, was the fact that Universe 7 had so many Supreme Kais at once at some point compared to the other universes. Why was this the case? Of course, out of universe it is likely that the other Kais were simply not taken into account (until Daikaioshin returned in the Moro arc). In universe, this still does not make as much sense.

What we do know however, is that there were 6 other universes that existed and they were erased by Zeno. What if the other Kais (North, West, and South) were simply refugees from the erased universes? This does not account for the other 3, but it could make sense. The Old Kai was sealed away by Beerus, millions of years pass and Nahare is selected to replace him. Universes 13-18 are erased by Zeno as well, leaving their gods effectively homeless. Daikaioshin sees this as a perfect opportunity to train Nahare and temporarily house these Kaioshin, it is a win-win situation. Unfortunately, beings like Moro and Bibidi (with Buu) would compromise this situation leading to what we have now, but it seems like perhaps the Daikaioshin may have had a plan.

As for the other unaccounted Kaioshin, the missing Gods of Destruction, and their Angels? Honestly who knows. Maybe the Grand Priest got involved in dealing with that once word got to him that the Daikaioshin was gone forever after being consumed by Buu and sealed away. This is a piece of lore that has not really been expanded upon and probably never will, but it is nice to at least give it some proper meaning within the world of DB.
