Ian's aunt bears a striking resemblance to her sister Kureha, so much so that even their father could confuse them. Her true name is Lucifera, and similar to Kureha, she belongs to the Leannan-sidhe. Unlike Kureha, Lucifera was once a customer at Kaito's shop, and now no one—not even Ian—can discern her fairy origins.
Her demeanor is notably more unruly compared to her sister; she has no qualms about breaking into houses or disabling security systems. Lucifera swiftly detects Ainsel's power and inquires of Kaito whether he intends to destroy the world. It is suggested that she harbors feelings for Hasumi, though nothing ever materializes from this.
