One thing I will say is that I think the whole thing with Azure-Project is supposed to be viewed as an all-or nothing affair. I'm not sure they did the greatest job at selling the player on the idea that it necessarily has to be that way, but I think it's supposed to be that once the project starts it somehow flips a switch in the nature/scope of KeA's powers which needs to be undone for reasons people have already said, and then once the SSS puts a stop to that she loses all of her powers.
I'm not sure if there's any clear reason in the rules of how the Trails universe works why KeA's powers couldn't be used in a smaller scale in ways that are obviously good and don't end up self-destructive for KeA, but I think the Azure-Zero Project is not that solution ---
I didn't do guru this year but azuarc can be in my sig anyways.
