Wow, what an amazing chapter. <3
I'm totally in awe. Where should I start? Well, first off, Rinne Tensei no Jutsu being meant to be used for Madara was stated in this chapter. So there's definitely a connection between Madara, Tobi and Nagato. Though that theory was pretty obvious, this chapter completely confirmed it.
Madara's power.. well, I was once more surprised. Not just that his ocular powers allow him to tell the difference between Kage Bunshin and the real one, something that was said/thought so be impossible and couldn't even be achieved by Neji's Byakugan, but his fan, Uchiha Gaeshi, allows him to deflect a mini Bijuu Dama. That Chakra shield he used to block the stakes was pretty impressive, too.
The Kage.. well, I'm happy that Madara finally stopped messing around with them. They're totally screwed, especially Tsunade. Being torn apart by a trunk is really cruel. The more I'm impressed that she still has the power to probably safe the other; and the more I'm disappointed in Madara, being so reckless with her, despite being aware of her extraordinary medical skills. I'm pretty sure that Tsunade will die a heroic death soon, though I wonder what she meant when she said 'Take the Kage to where I am'. We'll see when ***********'s translation is out. As for Kishimoto skipping the end of the fight; that was absoulutely no mistake, so stop complaining. It helped building up the suspense on what has become of the Kage; their total defeat was perfectly revealed in this chapter. It wouldn't have helped anything if we saw how he actually defeated them. He already displayed his clear superiority; showing him slaughtering them with the very same powers we already saw would've been pointless and a waste of a chapter.
Now for the most interesting part: The flashback that's introduced at the chapter's very end. So it's confirmed that Madara lived a very long life and, in the end, died as an old man. With that being shown, it's also clear what Kabuto meant with reviving him beyond what he was in his prime; he 'merely' summoned him in a younger state, with all his powers he achieved up to his death. I'm very excited about the next chapter; this flashback will most likely solve most of the mysterys surrounding Tobi and maybe even Zetsu. This is what we all waited for so long.
This chapter absoulutely deserves five stars.
