Contrat

The Contrat (契約 (クントラット), Kuntoratto; French and Japanese for "Contract") are a certain group of individuals who, regardless of origin, have either invoked the great power of the beyond or inherited said power from their ancestors.

The world of both mortals and spiritual beings are a host to a particular group of individuals who, despite not having the ability to earn it, covet greater things than whatever they could ever hope for; these individuals are those who have become prey to their own ambition, a deep wanting for health and wealth, a deep-rooted fear of mortality, thus conjuring a desire deep within their psyche that they deserve to earn these things above anything else. While most simply shrug them off, accepting the fact that they will never achieve such ambitions as a belief they call fate, a certain few who are willing to go the distance will go to such lengths, even as far as invoking the power of the 'gods' to achieve them and in turn, return something of equal or greater value.

While many mortals place their faith in such 'gods' that whatever they desire to possess shall be satisfied, spiritual warriors like the Shinigami know well that such 'gods' do not exist, and in their place stand a band of spiritual beings far stronger than they are whose existence play a much more major role in the cycle of life instead. However, shaken by the thoughts of having an army of their own or whatever the mortals offer them, a small percentage of these beings, despite their position, accept their offering, and in return, allow a fraction of their powers to be borrowed by the mortals in order to achieve their petty goals and desires. These individuals are dubbed the Contrat.

Due to the nature of their origin, the Contrat, regardless of physical or spiritual matter, possess a wide variety of supernatural powers, quite akin to that of a Shinigami, or simply the ability to resist whatever curse that hampers the progress of their life force in a similar fashion to the relationship between Jūshirō Ukitake and Mimihagi, granted by the 'gods' they deeply adore and worship. In a similar fashion, the descendants of these original contractees may or may not inherit the remnants of such powers and abilities, becoming quite like their ancestors.
