Judging by the current situation, the outcome of the battle between the Contractors of both sides is hard to predict.
Although the Contractors of Reincarnation Paradise are all exceptionally ruthless, faced with the harsh survival environment of Reincarnation Paradise, the Contractors either go solo or form adventure groups, making it impossible to establish a super large organization.
Moreover, most adventure groups are not large in number; a small adventure group might have only a few or a dozen people, and even a large adventure group rarely exceeds three hundred members.
This is related to the character of the Contractors in Reincarnation Paradise, where the strong survive and the weak perish. Although powerful Contractors emerge one after another, the number of casualties is also high. In such survival conditions, the chances of conflict among Contractors are greater, making the formation of large groups even less likely.
