Crystallized Beads

These crystallized beads are in no meaning regular. It was a common attire to possess two of these beads in Yūki's temple as a high priest. But for a reason the temple offered Yūki an unique bracelet that had twelve of these attached on it. In the matter of uncovering, Yūki managed to understand that the beads would return to him, if he called out to them and often is seen to be using it as shields to deflect incoming physical attacks. However, their true ambition lies to seal away the powerful, unique spirits that Yūki created, and summon them upon his command. These souls as well are noted to be undying as long as their life span deems so, which depends onto the fuel that lowers every time the spirit heals itself with fatal wounds, and can only be fueled with other souls. These souls/spirits are also referred as Shikigami.
