Just a thread for theorizing about what the rings that every Akatsuki member wear does.
Facts about them are as follow, they're obviously very important, since without them a new member cannot be inducted into Akatsuki, they also seem to be irreplaceable since there is still only nine members years after Orochimaru had left the organization. They are also placed on finger that the particular member belongs to on the statue. The kanji on each ring are unique and they often represent constellations or other mythological entities and concepts, the specific character and their meanings can be found here.
Inferences that I've made are as follows:
They seem tied to a specific person's body, when Sasori switched bodies, all articles of clothing were left on the previous puppet, though his face, eyes and heart talisman were transported, the only visible non-organic item that was also transported was the ring.
They may be used for communication, this is seen when the AL speaks to Hidan and Kakuzu. If he can target this at everyone, it would be safe to assume that he already has god-like powers, anyone can be driven insane by his voice in their head, no matter where they are.
They may be used in the sealing ceremony and other gatherings, this follows the same logic as the for communication via the rings, each ring is tied to a finger on the statue, and without a ring an applicant cannot become a member, it also follows that not everyone will be capable of learning what seems to be a rather complex jutsu in a very short period of time (Tobi was sealing biju just days after becoming a member and Hidan still didn't know what Akatsuki's goals were).
They may act as a form of duress for the lower members, this can be seen by the fact that Deidara was more concerned with recovering his ring than with recovering his arm, and Hidan suddenly stopped arguing with the AL despite the fact that he hadn't completed his ceremony. This argument isn't very strong, but there has to be a reason that everyone obeys the AL without him showing any outwards signs of aggression. This assumes that after putting the ring on, going without it for long periods of time will result in death or incapacitation in some other manner.
Any other thoughts about this?
Not necessarily death, or any sort of curse, otherwise Orochimaru would have died. Besides, if they carried a curse, or something of the sort, Sasori, or Hidan wouldn't have acted in a defiant manner, in front of the leader, I think.
I think that the rings connects them with Anima, I mean, the statue; as you already pointed out, each one of them wears a different ring, in a different finger; the finger in which they wear the ring, is the finger that they occupy in the statue's hand (I guess). I also think that it is not necessary for all the rings to be there, just that when all the rings are in use, the extraction may be easier. That may be the reason why the leader said that it was easier to do, when Orochimaru was around.
It being a medium for communication is also a good idea, yet, I think that it may be an ability or technique of the leader. Still, it is a big possibility that it works that way.
^ I know, that's why I said that the last inference was the weakest one, still, both Orochimaru and Sasori were not tied to one particular body (and I still think that Sasori isn't necessarily dead).
I also have some thoughts about why the rings are irreplaceable and why Akatsuki is operating on a timetable, but that isn't exactly relevant to this.
As I said before, maybe the rings have some sort of control over the bijuu. Each member has control over one bijuu and the leader has control over all of them.
If it were that way wouldn't they be more concerned about getting Orochimaru's ring?
Does make sense though, the biju are bound to the statue and the statue is linked to the rings.
If they are part of the ritual, they ARE important. They may be able to lose one, or two, but if they lose a certain amount, they, most likely, will not be able of performing the ritual.
This theory might not even work but I feel like I should put it out there.......what if the rings are the things used to summon the biju, I was thinking that they might be somthin like the sumoning justsu areement with the biju,kinda like the one naruto has with the frogs.......if it is retarded, try not to flame me too much.....
Well it is retarted, given that bijuus arent summoned, but rather take over you.
^ That's not what the AL said they were for.
He has some manner of controlling them (unless he just plans on a catch and release and re-catch policy).
As for the rings summoning them, that is a bit too specific right now, though if it related to the astral projection ability that they all use (which the rings are not necessarily related to, I just think it is based on what we've seen so far), it should be able to transport other forms of chakra, though it's unclear whether it matters that these conglomerations of chakra are the size of small mountains.
my guess is that the rings are related to biju some how, whether a specific one or not i have no idea.
Originally i thought that maybe the rings weaken in some way the biju when around them.
