This chapter was epic; we even got to read it earlier than usual!
It's pretty much confirmed that Orochimaru is a master of immortality. Despite being sealed by Totsuka Blade, he had planned for his death in advanced with Curse Marks and even through Kabuto. Perhaps he'd be even more powerful if he absorbed his chakra from all his test subjects?
Also, since Orochimaru absorbed his own chakra from Kabuto, does that mean Kabuto is back to normal? It seems that he might not be able to use Sage Mode again, since he's reverted to human form.
Did anyone notice that Anko no longer has the Curse Mark? Tbh, I kinda happy about that, since she's always been suffering because of it. Now she's totally free from Orochimaru (as long as they don't encounter each other xd). I wonder what they'll do with her?
Can't wait to see which duo Sasuke plans to meet. Is it his parents, Hashirama and Hiruzen (could the scroll contains a way to bypass the restrictions of Edo Tensei? :shrug

, maybe it's Madara and Tobi? Or maybe even Madara and Izuna?
The manga is really heating up, and it's awesome to see Orochimaru back in action. Hopefully he'll show us more of his power, which we barely got to see last time he was around. I hope he's more sly and calculated, after learning from his last mistake, in his attempt to steal Sasuke's body this time around. xd
5 stars out of 5!
