If BZ was kaguya's will all along wouldn't it make sense for it to be connected to her in ways more than just her will to 'exist'? It looks as if she's completely aloof to what's been going on. If madara realized that naruto and sasuka got powers from hago then BZ would have known too. In short...
lets say you were some sort of co writer or something and you discussed ideas with kishi. what would you change? what would you suggest? what would have been different?
I'd like to read some interesting stuff.
