───Ayakashi, Apparitions─────────────────── Danger levels exist: Calamity ▶ Menace ▶ Scourge ▶ Impurity. The higher the level, the stronger the arts and curses. Abilities are less effective against high levels. They attack or kidnap humans. Some Ayakashi can speak, while others cannot. Apparitions have no physical form. ──────────────────────────

~ 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 an Ayakashi becomes a Shikigami, they fight together and help each other, bound by a deep bond. The contract cannot be canceled once made, and an exorcist can only contract one Ayakashi in their lifetime.
