World Fool Eye(魂を映す鏡ワールド・フール・アイ, Wārudo fūru ai), also known as Mirror that reflects the soul, is the Sacred Gear of Mira Kagami, the bishop from Lucrezia Andras's peerage in the DxD: Haremonogatari continuity. A Sacred Gear that works on meta-physical levels, it allows the user to manifest physical manifestations of its victim's self-awareness.
