Kage fighting was certainly a refreshing change back to something other than Kabuto and genjutsu. Though I fail to see the significance of Perfect Susano at this point. If anything, it is a plot device to foreshadow Sasuke getting it (which would be crazy OP but then again when is uchiha not...). Though, it seems probable that it will be how Madara kills Onoki before being released from Edo Tensei by Itachi... that is if Kishi doesn't troll and have Kabuto miraculously break Izanami. Anyway, we all know that there is going to be more talk between Sasuke and Itachi - he promised to spill the beans about something way back in beginning of Kabuto fight.
Awesome chapter. Much to discuss.
