It’s just why does she need to voice Son family and not just get one or two voice actors for them. If she passes away I will riot if they retire the franchise.
Not likely to happen - the guy who created it tried to kill it and it is still going strong...
At least the "legend" is that, when the manga were really taking off and the second DragonBall series was in production the guy who created it asked for a month off. The studio said: "Give us enough material to cover two months and we'll give you one off."
He then produced at least three, possibly more, issues that were nothing but characters powering up during a fight, and maybe a page or two with other characters either on side stories or reacting to the power-ups.
The studio accepted this and gave him his time off.
Then the shows caught up to those issues of the Manga and they said: "We need you to write us a few scripts." "I already did. If you need more than that, get someone else to do it."
And thus they filmed a few episodes that were also nothing but characters powering up because that's what he had written!
If the franchise can survive tomfoolery like that it will survive just about anything.
