Relic Eaters are the strongest weapons held by the Inquisition's members and serve to assist them in combat against magic-users. Relic Eaters are contracted exclusively to the members of the Dullahans, the highest-ranking Witch Hunters. These weapons have their own unique identities by choosing owners that best fit their abilities and specifications. They were created by Sougetsu Ootori who is able to discern the status of each Relic Eater that he gave to his Inquisitors and order them remotely.
Relic Eaters primarily take the form of weapons while others choose to stay in human form. The characteristic of transforming into different types of weapons to fit its user's needs is a common feature among Relic Eaters. An exception to the below list would be Lapis as her origins do not lie within the Inquisition-made Relic Eaters, and her proper categorization belongs in the classification as a Magical Heritage.
