Yay, so great to see the 5 kage again! And they kicked ass too. Oonoki is such a beast; just goes to show how important experience is. A bit disappointed that we seem to have missed half the battle, but it was probably just as boring as the last, repetitive part of the Uchiha bros vs. Kabuto fight anyway.
The kage seem to be in quite a pickle though. Oonoki said they don't have much chakra left, and now Madara's released the perfect Susano'o. Damn. That is however an opportunity to finally have a major character death in the war. Don't get me wrong, I like all of the kage, but someone seriously should have died by now. It's been a long time coming.
Those Susano'o.. clone... things are really creepy. They actually kind of look like the spirits from Spirited Away. *shudders*
Naruto must've really made an impact on Itachi, to make him belive he can convince Sasuke that what he's doing is wrong. I'm quite disappointed that we probably won't get a discussion about the subject or at least some kind of semi-casual conversation between the two brothers - I had really been looking forward to that. I agree with Itachi's priorities here though; help the shinobi world or try to knock some sense into Sasuke? Save the world. Hell yeah.
But if he cancels the damn Edo Tensei without Madara going out with a bang, beaten/sealed by the kage or having defeated at least one of them, I'll be seriously pissed off. I know I'm not the only one, and I hope Kishimoto realizes this. His priorities in the war so far have been... off, so it's a possibility he'll troll us once more. He better not!
Also.. Mei, darling, next time you go to war don't put on a dress. They're quite impractical, and obviously break rather easily. Noob wardrobe malfunction. xd
All in all good chapter!
