Spheres of Power

The Spheres of Power were small, colored spheres which granted the four demons of the Shitōshin their power. They were sealed by a priestess named Kanade on Hōraijima into a small comb box and hidden inside the Cauldron of Resonance. The Shitōshin were able to recover their powers eventually, but in the meantime had to sacrifice live half-demons into the Cauldron to sustain themselves.
