It was said that thousands of years ago wolves who could take the shape of a human form once ruled the world.

Thousands of years later, the world is conrtolled by either a government or a dictator.

However, some legends say that today, in the forests, those same lineage of wolves still rule there, each having their own pack, and each having it's own human backbone to help provide for them when needed, but most of all, to help keep their secret hidden. The wolves mark their mate, they mark their territory, and they mark their enemy. Some believe these legends, others think of it as a joke... but it is true.

One pack of wolves, consisting of eleven members and different from others, one human, her sibling, and their enemy... there's bound to be trouble.
