Lullaby  

Living Magic, ゼレフ書の悪魔

The lullaby has two forms and therefore appears differently in each form. Its initial and default Flute Form is characterized by being unable to speak or move, having a size of nearly 50 centimeters in length, featuring a skull with three eyes on one end, an oval-like cutout in the skull's brow, and root-like cutouts on the other end. When it transforms into its Etherious Form, it becomes a tall beast that has three eyes, two legs, two arms, and one head, with many cutouts throughout its body. Initially, the lullaby was used as a tool for "murder by curse," which meant it cursed the target and caused them to die. After being in Dark Mage Zerefs possession, he further developed it into a magical flute called Mass Murder Curse Magic that could put a death curse on everyone who heard its melody except for the caster.
