In Naruto, every member of the Xiao Organization is a renegade ninja from all over the ninja world, and after they join the Xiao Organization, they will do the same three things, the first thing is to draw a knife on the forehead, the second thing is to dye nails, and the third thing is to wear the ring exclusive to the Xiao Organization, in addition, the red cloud coat has also become a sign of joining the Xiao Organization.

After the Xiao Organization was officially taken over by Nagato, the number of members of the Xiao Organization also began to decrease significantly, and the most stable time was that there were only ten people, and these ten people would also be arranged and distributed by the Xiao Organization, and the text on each ring was different, and the location of the Xiao Organization members wearing this ring was also completely different, why?
For example, the ring of the Uchiha Ferret, the text on the ring is "Zhu", representing the Suzaku, the Uchiha Ferret wears it on the ring finger of the right hand, in the battle, this ring does not seem to have much effect, it seems to be just an ornament, but when the Xiao Organization began to seal the tailed beast, these rings also played their role.
The Xiao Organization usually acts in groups of two, but no matter which group catches the tailed beast, everyone in the Xiao Organization must participate in the sealing process together, but the members of the Xiao Organization are relatively scattered, and they will not spend a long time returning to the gathering place in order to seal the tailed beast, so there are these ten rings, and the Xiao Organization can gather together through these rings.
When the Xiao Organization sealed the tail beast, ten words would appear on the hands of the Outer Path Golem, and these ten words corresponded to the words on the ring of the members of the Xiao Organization, and each member corresponded to one finger of the Outer Path Golem, and the finger that did not light up meant that the member was either dead or had not yet found a new member to join.
So for the Xiao Organization, this ring is a very important prop, after the death of the Red Sand Scorpion, Uchiha took the soil to find the ring of the Red Sand Scorpion, although nominally to become a member of the Xiao Organization, but for a ring to return to that place, which is enough to see the importance of this ring, Deidara broke his arm, but he also cared about the ring.
In the author's setting, each ring also corresponds to a different meaning, so each person's corresponding text is also different, these words also represent the personality and wishes of these people, and the members of the Xiao Organization can stand on the hands of the Outer Path Golem through these rings, which can also be speculated that the raw materials for the production of these rings are part of the Outer Road Golem.
Among these rings, there is one ring that is the most special, that is, the ring with the word "empty", except for this ring, the rest of the rings are all in the hands of the Xiao Organization, and this ring is in the hands of the Great Snake Pill, so every time the Xiao Organization gathers to seal the tail beast, the fingers corresponding to the "empty" of the Outer Path Golem are always empty, because this represents the Great Snake Pill.
So it can also be understood why after the Great Snake Pill left the Xiao Organization, the Xiao Organization still had to keep hunting down and killing the Great Snake Pill, in fact, killing the Great Snake Pill was not the purpose, the most important purpose was to find the ring that the Great Snake Pill took away, after all, only by holding this ring could you participate in the seal of the tailed beast, so it was meaningful to join the Xiao Organization.
In your opinion, why do members of the Xiao Organization wear rings?
