Innocence (イノセンス, Inosensu), also known as Anti-Akuma Weapon (対アクマ武器 , Tai Akuma Buki, Literally meaning "Versus Akuma Weapon") when invoked by an Accommodator and as the Crystal of God (神の結晶 , Kami no Kesshō) by those who first used it seven thousand years ago, is a mysterious material and the power source that drives the Black Order. Innocence is also the weapon that Exorcists (エクソシスト, Ekusoshisuto) use to defeat and purify Akuma.
