Six fallen angels have returned from the Realm of Nothingness; Absolut, Bonbour, Brandi, Morgan, Rosé, and Bambay. Absolut is their leader and the most powerful; a dark teacher twisted by the fate of Universe 13 who wishes to kill Delphinia and re-claim his post atop his own father, Daishinkan. Bonbour, Brandi and Morgan were angels of Universes 14, 15, and 16 respectively and wish to re-claim the universes of their twin sisters, Cus, Vados and Marcarita, angels of universes 10, 6, and 11. Rosé is the mother of Delphinia and former angel of Universe 17. Bambay is the former angel of Universe 18. In order to defeat the children of one of the most powerful beings in the universe, Goku, Broly, and Vegeta must unlock and master a power not even Gods of Destruction have mastered; Ultra Instinct, or else be exterminated by these returning vengeful masters of power.
Delphinia's father was a mortal who fell in love with Rosé, making Delphinia the first being of her kind. As such, Delphinia possesses all of the strengths of an angel and a mortal, as well as all the weaknesses.
Primella is even further away than her mother is from ever being a pure bred angel, but her power may be one of the biggest inspirations her father-in-law needs to attain the power necessary to fight off three of the most powerful adversaries he has ever faced.
