Mangastream always has the chapters up on Wednesdays in English. I looked up the technique last night and after a little bit of thinking I grasped that you don't need the actual bodies. Does anyone remember what "that" Jutsu is? Is it the fox cloak?
Not the fox cloak. "That" jutsu has never been explained. It's probably some jutsu that the Fourth Hokage wanted Naruto to complete kind of like the Rasengan.
Naruto has already kinda done the whole fox cloak, albeit not under his direct control most of the time.
