Devil's Eye (鬼人の眼, Kijin no Me) is magic based around the use of Hades' right eye, which is usually covered by an eyepatch, this Magic has to be "awakened" in order to activate its yet unknown effects. Its use prompts Hades' hair, beard, moustache and eyebrows to jut out, and releases a vast amount of Magical power around him. Through the use of it, he claims to show his opponents the "Abyss of Magic".
