I like Daima so far. It brings a new story and adventure. I do like that the demon realm is outside of the 12 universes. That is, each universe doesn't have its own demon realm but that it is distinct and exists in its own plane of existence. In Super, when we found out that Jiren's master was killed by an unknown demon and that is what motivated Jiren to become stronger - I wasn't sure if Universe 11 had its own demon realm since that demon would have to be even stronger than Majin Buu and Dabura to be able to kill Jiren's master.
Now we know that the demon realm is divided into 3 sub-realms, each with its own king. Dabura was at most Perfect Cell's level and his father, Abura, while unknown, doesn't seem that strong but maybe with the third eye, he could be. The necklace around Abura in the ending credits could be that third eye.
Also, while this opens the possibility of other demon realms, I wonder if Mechikabura and Towa still have a role. Towa was Dabura's sister and she was originally designed by Toriyama. Perhaps it can be explained that Towa has her own agenda and is busy making Mira and doing her time travel shenanigans at this time. Mechikabura could have been the original demon king as "abura" is part of his name. Before you say anything. Yes, I know you will say that it's not canon but Toriyama did in fact design the characters in Dragon Ball Online which ended up becoming Xenoverse. DB Heroes based the stories off that.

I can translate the Japanese version of Toriyama's message at least:
Hey all you Korean DragonBall fans, it’s been a long time. It’s me, Akira Toriyama.
This new DragonBall story that we're delivering to you this time begins in a world 250 years after the manga.
There, Earthlings, Saiyans, Namekians, Majins, and others all live together, but it seems that something is wrong.
What occurred in those 250 years, and what’s happening now? Please enjoy this new DragonBall world as you resolve this.
Everyone on the excellent staff really drew a lot of new characters and machines for me. Of course, I supervise them all. There are also a lot of designs in there that I drew myself.
When I actually got to see the pictures in motion, I was truly impressed by their high quality!
It’ll make me happy if you fully enjoy this new world of adventure, this time online!
Akira Toriyama
It's also interesting to note that if the origin of the Namekians is the Demon realm and that Neva is able to exert so much power over another set of Dragon Balls, gathering them in their inactivated and even reactivating them, shows that he is from the Dragon Clan of Namekians. We also know that Zalama is the creator of the Super Dragon Balls and he has to be alive given that the Super Dragon Balls exist. Perhaps, this gives us clues to the origin of not just the Namekian species but also Zalama's origins and where he/she/other could be.
