Ushi no Koku Mairi

&nbsp Ushi no Koku Mairi is a Lost Magic utilized by Grimoire Heart member, Kain Hikaru. The magic is involved with Kain's voodoo doll, Mr. Cursey. First, Kain places the hair of either himself or of someone else into the doll. After that, if someone manipulates the doll, the "victim" is manipulated in the same manner. This was demonstrated against himself when he placed his own hair into the doll and handed it to Lucy, who proceeded to slam the doll into the ground, which led to him doing the same. However, a second aspect of this magic is that Kain can magically alter the doll's properties, allowing him to change his own properties in the sammer. For example, by turning his doll into iron, Kain can do the same with his own body.
