Living Magic (生活魔法 Seikatsu Mahō) is a form of Black Arts utilized by Zeref. Like the rest of the Black Arts, "The Book of Zeref" is written how to obtain and use this magic.
Apparently a very 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.
- Lullaby (ララバイ, Rarabai 呪歌, Cursed Song) is one of Zeref's evil creations and a Living Magic spell. In flute form it can't speak or move and its size is nearly 50 centimeters in length. It is probably made of wood and it has a skull with three eyes on one end. There is an oval-like cutout in the skull's brow. On the other end there are root-like cutouts. The flute can transform into a giant demon. In the full form the flute is nearly at 60–65 meters high. It has three eyes, two legs, two arms and one head. There are many cutouts in its body. The flute was once just a tool for "murder by curse" at first, which means that it curses the target and causes it to die. After getting into dark Mage Zeref's hands, he further developed it into a Magical flute, called "mass-curse murder magic" that is capable of putting a death curse on everyone who hears its melody except for the Caster. Whoever hears Lullaby’s song (aside from the Caster) will die
