Apparently an ancient, long forgotten form of Magic that brings things to life under the caster's control. Some creations of Zeref, mostly gigantic and powerful demons, have minds of their own, and continue his unknown evil quest. In "The Book of Zeref" it's written how to obtain and use this Magic. Maeloc however did inherit and learn it from Zeref itself as Maeloc is now able to make an different subspecies of Demon.
 * Hunter (狩人 Yaegers): Yaegers are the unique subspecies created through Living Magic by Maeloc. The monster subcategory are creatures of a highly toxic nature and have been categorized on the "Dangerous". Each Yaeger is classified under numerous different categories. The Great Scale measures water displacement, toxicity and ambient radiation levels given off by their bodies . The fluid of a Yaeger is ammonia-based. Should they be killed in battle, their bodies are triggered to self-destruct immediately. Maeloc didn't create the humanoid subcategory of them however.
