Anyway I thought it was spiritual arms, because that justsu steals the soul of the person, putting it in a vessel and the maker and the one who receives will battle eternally...

Where we mighty discover sometime from now that Naruto is with the 4th and nine tails within, or that naruto is the 4th and has to battle kyuubi forever, or whatever...

For this kind of justsu I thought it was the spiritual arm that was broken, thus he needed a healer, because if it is not that, so there is no point in looking for tsunade, just take anyone body asap...
