A boy cursed with the power to petrify everything and anything he sees. Eventually he petrifies Kainé and years later he requests for Nier to help him find a cure for reversing the effects in a laboratory in his mansion. While in the laboratory, Emil remembers that he was experimented upon in the search to create an "ultimate weapon". His sister, labelled Number 6, became the ultimate weapon while he was known as Number 7 and kept in reserve. Their mission below the mansion is successful and Emil gains the power to use other magic spells and reverse the effects of petrification, but pays the price: he transforms into his sister's "weaponised" body, a skeleton-like creature that hovers above the ground, wearing a robe and wielding an enchanted staff.
