Devils are generally large and humanoid in appearance with pointed teeth, horns, tails, and bat-like wings. Every devil seen so far has access to particularly formidable and frightening forms of magic, such as Anti Magic and Kotodama Magic.
Normally, devils cannot appear in the living world on their own. A mage can use Forbidden Magic and a sacrifice to summon a devil and use its power. Devils cannot wield or enter a grimoire until it has a five-leaf clover. Once they have a grimoire and a physical body, they can unleash their true forms and power in the living world.
