Naruto is assumed to have learned "that jutsu" from Ero-Sennin. Maybe he will use his cloak to sprout chain from the entire alliance..? I don't know. I've always thought "that jutsu" had something to do with Kurama..so who knows. It makes sense in a way..."damn you uzumaki's, ruining my plan again"...Creating an opening for TNJ to be applied as well because Madara is just lonely. (lol)
