and

"She can easily supercede any event god has designated to occur ont the ground level. This power violates the realm of god."

You can't really upgrade an ability like that unless it becomes pure time reversal.
Maybe her upgrade wouldn't necessarily be something like Chad's or Ichigo's upgrades. It could be something like being able to do a better job with her current powers. For instance, maybe she can completely heal someone in two seconds or something. Or her shield could reject even a Cero attack at close range. And Tsubaki could actually do something. That little bastard can't seem to do anything.
