^ Well Tsunade just got the Dan-loves-you-plot-shield
Though it is questionable how long that will hold considering right now she is the only one who can fight him for a brief time considering she got her chakra back and the other Kages are pretty much empty. - So it might be her trying to protect the Kages till either Naruto or Sasuske arrive?
I dunno, somehow this little seal trick has a smell of shallowness, Madara haxing himself ok, was to be expected I guess, but did it have to be another asspull? Rinnegan would have been more believable ?
