This is kinda like an Alternate Ending of Wolf's Rain.

~The original pack of wolves has lived defeating Darcia and Jagura. Time has passed and the original wolves have not seemed to age. More wolves have arrived and are trying to find the originals and learn from them. Many though do not wish to learn and instead try to disrupt the teaching. Packs are formed sometimes, and loners are common. They live anywhere and in anyway they can. Some live the lives of pampered pets, others mangy scoundrels lurking for a bite of food, others still live as the wealthiest people in the area and others are mere beggars roving from town to town trying to survive.

The original wolves are and who they're play be already, if it says unknown they haven't been created yet:
Kiba (Kiba)
Tsume (Cheza)
Toboe (Kiba)
Hige (Unknown)
Cheza (Cheza)
Blue (Unknown)
