Demon's Eye (悪魔の眼 Akuma no Me) is a Caster-Type Eye Magic.
This Magic is based on the use of one of the caster's eyes, which is usually covered by an eye patch. This Magic has to be "awakened" in order to activate its as-of-yet unknown effects. When Hades used it, it made his hair, beard, mustache and eyebrows jut out, and a vast amount of Magic Power was released. Hades claimed that it was used to show opponents the depths of Magic, which is a realm that surpasses their imagination. It is also stated to be a way for the caster to reach The One Magic world with Zeref's awakening. This Magic can be deactivated by simply closing the eye using the Magic.
Black Arts (黒魔法 Kuro Mahō): Through the activation of Demon's Eye, the user is able to perform one of Zeref's infamous Black Arts.
- Living Magic (生活魔法 Seikatsu Mahō): Through the activation of Demon's Eye, the caster is capable of using Living Magic: a form of Magic that brings life to creations.
