The Great Wolf Conglomerate is a chain of corporations that secretly houses and masks the interests of a clan of Good Shinobi. The conglomerate considered the Phoenix Conglomerate to be it's number one competitor.
Rivalry with the Phoenix Conglomerate
When Ikaruga was adopted into the Phoenix Conglomerate, the head of the Great Wolf Conglomerate decided they also needed to adopt a daughter to represent them in retaliation. This ultimately ended up being Murakumo. Because of this, Murakumo resented Ikaruga, as she sees her as the cause of being separated from her adopted family.
