While Michael was busy dealing with all of the business in the Grafted Cluster, the Shadows of Reborn was busy dealing with all the behind-the-scenes stuff that was happening all around the Reborn territories.
Their job was to spread eyes on all the corners that the Reborn company had its hands on. They used their unique clone and shadow skills to have surveillance over every single thing that was happening in their visible world, whether they be insignificant gossip from neighbors or large bandit conspiracies that threatened to disrupt commerce on a large scale—they heard it all.
The Orcanine Orcs, with their specialties in offense, were given the more aggressive tasks during ninja missions. This included infiltrating foreign territories, surveilling persons of interests, etc.
The Orcupine Orcs, on the other hand, were tasked with protecting Rebornians and their assets from ne'er-do-wells with bad intentions.
