Kogure, Saya

小暮沙耶

Saya is a mysterious woman who is, at times, hidden from the view of most people. She is the Tachibanas' next-door neighbor and works in the fashion industry.
However, this is merely an illusion—she secretly manipulates circumstances in Ichika's life to compel her to use the power of the Djinns. She can move anywhere at will, transform her scarf into a deadly scythe and other objects, and keeps a watchful eye on Ichika throughout the series. She strictly enforces rules regarding the activation of the stones: the current bearer must remain completely unaware of their true nature and purpose, and no one may interfere with the bearer's decision on whether to use the power.
