my one question is; wasn't the 3 tailed beast ROAMING FREE (the one deidara and tobi caught) without a host? and arent there supposed to be a total of 9 tailed beasts. with this, only 8 jinchuuriki, yet the picture shows 9. seems like a bit of inconsistency with the author but at this point with all the other crap he's pulled out of his ass it seems to pale in comparison.
Maybe one of them managed to break free from its host or some dumb shit like that...
