~ Shikigami Contract ~
An exorcist can make an Ayakashi their partner. This is only possible with mutual consent. A contract is formed through a special ritual. Once a Shikigami, the Ayakashi fights and supports their partner, bound by a deep bond. The contract cannot be undone, and an exorcist can only contract one Ayakashi in their lifetime.
