Neither of these two requires any agreements. The regular yoma are like beasts or like a plague. You just set it free in secret and a little later appear as a savior to help people with the cure. All the better if your own tools (Claymores) get killed every so often: It makes it look even less suspicious that you had anything to do with it in the first place.Originally Posted by shinta|hikari
The problem with the Awakened beings is that no matter what else, the fact remains the organization makes a living out of hunting all yoma, including Awakened beings (it matters little to the ordinary people asking for help what manner of a beast it is that keeps eating them). And Awakened beings themselves seem to delight in killing Claymores. So, any trust there would be highly transient. It seems far more likely to me the male Awakened being just happened to have a personality that made him spend his time in that one place. There are people like that. The organization at some point took notice and started to use it as a waste disposal site.
