Diamond Wolves

The Diamond Wolves is a giant pack of wolves. There's one leader, a Successor, and the rest are normal wolves with Agents, which help them through.

The leader must have the pack howl the Acceptance Howl to become leader. If they don't, he is rejected and the wolves must choose someone else.

The Successor is the next wolf to lead after the leader is killed or died. They are chosen as soon as the other Successor is made leader.

The normal wolves just train in fighting and hunting and live together. There is no structure of Alphas, Betas, or Omegas, so any wolf can have a mate with anyone.

The Agents are helpers of the normal wolves, protecting and saving them with their lives if they must. They are trained since they are pups in their duty.

SPOILERS BELOW

The audience is probably wondering what happens to the Diamond Wolves after Story 8 because they are left without a leader and we never seen Stone name a Successor. The pack also ends--they have no order and are soon fighting amongst each other for food and rule. Eventually, there are only a few survivors, and these survivors either run away or are wiped out with disease.
