For anyone wondering the scanlated release is out.
Nice chapter. I want to know what the final secret is. I am wondering if it's immortality? That would further add to why Oro wanted Sasuke's body, and explain why Madara is still alive, or it could be something as simple (and already stated) as you can control the nine-tails (and whatever other bijjuu or whatever they're called). That could also explain how he caught that one water one (was it the four tails? I cannot remember) when it looked like he was loosing. He could had just started controlling it.
I guess this also means; if Madara controlled the nine-tails "like a pet" he was the one who let it loose on the village when the fourth sealed it.
